[Zz] hd7970ge vs gtx770

AMD/nV beacon smoke again! Hd7970ge vs. gtx770

Bubble net video card channel in July 8, the high-end market shoulder the strength of the display manufacturers, set up the brand image of the task, has always been a battle for soldiers. From gtx680 vs hd7970, hd7970ge vs gtx680 and then to gtx770 vs hd7970ge, A/n's two companies are able to face each other in this position!

In terms of naming rules, AMD is a kind of good. When hd7970 is added to boost technology, the basic frequency also increases from MHz to 1 GHz at a Glance. It just adds GE to the original name to show the difference, while NVIDIA also upgrades gtx680, the name is gtx770.

NVIDIA's computation in this way not only makes it easy to fool the white, but also saves more effort in channel shipment. It is a high-end suppression flagship, and it is no shame to lose it.

The overlap between Tahiti and gk104 positioning has led to a long and unfinished war. With the launch of gtx770, this has started a new chapter for the family ......

 

Large competition of hd7970ge and gtx770 specifications

First, let's take a look at NVIDIA's public version. As NVIDIA's current next-high-end model, gtx770 is not a strikethrough version of gtx780 in terms of hardware configuration, but is equipped with the gk104 display Core Used by GTX 680, in addition to the high frequency, the memory size is similar to that of gtx680. This gtx770 looks like an "Upgrade" of gtx680 ".

NVIDIA geforce GTX 770 GPU-Z

Gtx770 adopts the same gk104 core as GTX 680 with 1536 Cuda cores. The core frequency is increased to 1046 MHz, and the equivalent memory frequency is increased to 7012 MHz! With 2 GB gddr5 memory, the bandwidth is 256bit.

● Amd radeon hd7970 Ge

As the name suggests, GHz is the version with the GPU core frequency exceeding 1 GHz, but this video card is not as simple as converting the hd7970 overclock to 1 GHz. The Default Frequency of the previous hd7970 public edition is 925/5500 MHz, while that of the hd7970 GHz edition is increased to 1000-1050/6000 MHz, that is to say, the core frequency of the hd7970 GHz version will be dynamically adjusted between-based on the actual load.

AMD's automatic overclocking technology is named powertune, which is similar to Intel's turbo boost (turbo boost) and NVIDIA's GPU boost technology by detecting GPU loads, dynamically adjusts the GPU power and frequency, and controls the GPU power within the set range.

 

Although the Default Frequency of hd7970 GHz edition is improved, its TDP power consumption is not prompted and is still controlled at 240 W, this is because amd significantly reduced the GPU core voltage from 1.175v to 1.020 v.

Hd7970 GHz edition GPU-Z

AMD officially said that the powertune Technology ensures that each video card has a certain degree of Frequency improvement, so that everyone can get the same performance, rather than the "special selection" evaluation sample.

The following is a detailed parameter comparison of high-end graphics cards:

In terms of specifications, the hd7970ge stream processor, the number of transistors, the memory size and memory width are higher than that of gtx770, while the latter has a slight advantage in the core and memory frequency.

Test Description and platform Introduction

The video card used in this test is mainly positioned as the high-end flagship. During the test, all the special effects are enabled in all the games, including 4x anti-tooth (AA) and 16x heterosexual filtering (AF ). Although many games provide higher accuracy of AA, they are not tested because of their low practical value and no comparable performance.

Currently, some of the displays are (1920x1200). In this resolution, the performance of the game is similar to that of the 1920x1080, And the FPS is slightly lower, friends who use this type of display can still refer to our test results.

With the sandforce controller, ocz also upgraded the vertex series to the new sf1200 solution. Currently, the sata3.0 6 Gbit/s interface is widely used. ocz has launched the vertex 3 SSD Based on the sf2200 series master chip, covering a capacity range of 60-GB.

Latest 3D performance benchmark: 3 dmark

Since the platform is different, the test project is also far from each other. In addition to the ultimate performance of PCs, laptops and tablets are limited by the battery and mobile factors, and the performance is not very high. Therefore, although there are three optional versions of 3dmark11, still cannot accurately measure the real performance of mobile devices.

3dmark Main Interface

This futuremark has customized a proprietary Test Solution for the mobile platform. The precision of the three new-generation 3dmark scenes and the configuration requirements are almost different.

Fire strike, Cloud Gate, and ice storm correspond to the three most popular types of computers-desktop, notebook, and tablet.

The latest 3dmark software provides two test modes. hd7970ge delivers excellent performance and gtx770 is inferior.

 

Dx11 benchmark: 3dmark11

 

The focus of 3dmark11 testing is to use the dx11 API to update and render the complex game world in real time, and get a comprehensive score through six different test links, so as to judge the benchmark performance level of a PC system.

● 3 dmark 11 features and highlights:

1. native support for DirectX 11: Based on the native dx11 engine, all new features of the dx11 API are fully used, including surface subdivision, computing coloring, and multithreading.

2. 64-bit native support and 32-bit reserved:Native 64-bit Compiling Program, independent 32-bit and 64-bit executable files, and supports compatibility mode.

3. New test scenario: a total of six test scenarios, including four graphic tests (in fact, two scenarios), one physical test, and one integrated test, fully measuring GPU and CPU performance.

4. Abandon physx and use the bullet physical engine: abandon the closed NVIDIA physx and switch to the open-source bullet professional physical library. It supports collision detection, rigid body, and software, and is free to use according to the zlib authorization protocol.

3dmark11 creates a large number of special effects to make hd7970ge and gtx770 fail to run it smoothly. In this test, the extreme mode is enabled for video cards. This test item is the opposite of the latest 3dmark software test result. N cards play a significant advantage in 3dmark11, and GTX 770 is better than hd7970ge.

Dx11 games: island crisis 3

Island Crisis 3 supports a large number of high-end graphics options and high-resolution materials. In the game, PC players will be able to see a series of options, including game effects, item details, particle system, post processing, shadow, shadow, water body, heterosexual filtering, material resolution, dynamic blur, and natural light. Marco corbetta, the technical director, said that "island crisis 2" does not contain so many options because the development team of the motherboard is too slow.

● Real-time volumetric cloud shadows)

Real-time volumetric cloud shadows is a technology that combines the volume cloud, smoke, and particle shadow effects. Compared with other similar technologies, the Real-Time Volume Shadow technology allows dynamically generated smoke to possess volume and affect the light, interacting with texture rendering of other objects.

● Pixel accurate displacement Mapping)

Pixel accurate displacement mapping allows the cryengine 3 engine to render a large number of polygon without obvious edges at a time without using the dx11 Subdivision Surface technology. Previously, crytek revealed that it was considering using a host to implement a subdivided surface effect similar to that on a PC that requires dx11 hardware, the new displacement Paster technology is used to simulate the effects of subdivided surfaces. Although the implementation principle is completely different, the effect does not seem inferior.

Tessellated vegetation)

● Real-time area lights)

Real-time area lights evolved from pure simulated point light illumination and projection to regional illumination, and variable semi-shadow (that is, the blurred Effect of projection occurs with the extension of distance), more accurately simulate the illumination characteristics of the real environment.

● Integrated cloth & vegetation Simulation)

Integrated cloth & vegetation simulation is a good physical effect in the first generation of the solitary islands crisis, however, crytek has enhanced its performance in this aspect. In addition, it has added a physical simulation of the fabric material. In this regard, only NVIDIA physx has done a better job.

● Dynamic volume Water Reflection (Dynamic Water Volume caustics)

Dynamic Water Volume caustics (Dynamic Water Volume caustics) solitary island crisis 1 and 2 are basically concentrated in the performance of water, with few lakes and similar scenarios of Large Area pools, this time, crytek realized the dynamic reflection of the water surface with an ultra-distant view. Dynamic volume water reflection is an extension of local real-time reflection in the island crisis 2. It is a new water surface reflection technology that combines static environment sampling and dynamic effects.

The Treasure of the secret subdivision is amazing, and it can be completely fake!

As the benchmark for the quality of the next generation of dx11 games, the Gudao Crisis 3 has higher requirements on graphics cards than the previous generation. In this game, which represents the most advanced picture quality, gtx770 is better than hd7970ge!

Dx11 games: Tomb shadows 9

Over the years, we have seen many different forms of Laura, from the action game leader of breast fat buttocks to the wise nobles who like to explore Atlantis civilization. But we have never seen such Laura. Crystal Dynamics's tomb shadows 9 showed us a young Laura who participated in her first adventure. She was trapped on a small island with knives and guns, you must raise your own vision and desire to survive to the limit.

Story Introduction: from the young days of Laura, the "cool" called by Laura seems to have been called by fate. in the Sea of Japan, the devil's sea encountered a typhoon, unfortunately stranded. Laura was also forced to start her own survival experience on the island.

Compared with the previous generation, the game screen of tomb-Art 9 has increased a lot, and the gaming requirements have also increased a lot.

This is a comparison of games with different image quality. We can see that the quality of "high" special effects is already very good.

The Optimization of the card is very well done by tomb Photo 9. Although the N card driver is also optimized later, the game performance has been greatly improved, but it still does not surpass the performance of the card. GTX 770 is weak, especially in benchmark tests with high resolution.

Dx11 games: Battlefield 3

Battlefield 3, developed by EA dice studio, uses the latest "Frost 2" engine. It perfectly supports DirectX 11 and has powerful physical effects. The biggest highlight is the lighting system, the rendering scene is almost messy, and the visual effect is superb. The game also supports the real-time day-and-night system to create a real environment for players to visit the site.

The biggest feature of the Frost 2 engine is its support for large-scale damage. Considering the video performance and development costs of the game, dice gave up the Windows XP operating system that only supports DX9. In addition, because the engine is developed based on dx11 and is backward compatible with dx10, the game can only run on Windows Vista and later operating systems.

In Battlefield 3, the damage system built in "Frost Engine 2" has been upgraded to version 3.0. For some high-rise buildings in this project, the damage system of the new version will play the catastrophic effect of the movie 2012, and the sudden collapse of the building will shake the eyes of every player.

Battlefield 3 uses the ant engine to create the movements of characters. Prior to this, the ant engine had been applied in EA Sports's FIFA and other games, but it was the first time it was used in FPS games. Compared with physical engines such as Havok, ant engine can be used to produce realistic results with less effort. For example, when a warrior is squatting, he will bow his head and put down his muzzle, instead of moving his head, body, and gun like a puppet at the same time. In addition, the ant engine can make computer AI more reasonable. However, this masterpiece is not compatible with 120hz3d and red/blue 3D.

Frost Engine 2 is a big battle ground 3. It is one of the few pictures that can challenge crysis's game masterpiece, and its core and video memory requirements have exceeded crysis! The more abnormal the game, the more favorite the flagship graphics card. In this game, GTX 770 and hd7970ge are almost identical!

Dx11 games: Metro 2033

Game Introduction: Metro 2033 is a new work developed by the Russian studio 4A games and a new member of the dx11 game. The core engine of the game is a self-developed 4A engine that supports almost all image quality technologies today, such as high-resolution textures, GPU physx physical acceleration, hardware surface subdivision, and morphological anti-sawtooth (MLAA) parallel Computing of depth of field, screen environment light shielding (ssao), sub-surface scattering, Parallax textures, Object Dynamic blur, and so on.

Enable depth of field to simulate the image head

Screen setting: Although Metro 2033 supports physx, it also supports CPU Software Acceleration. Therefore, using the card to play games won't drag down the performance due to physx effect. This game has a lot of cutting-edge technologies that make it very BT, so we do not dare to enable anti-aliasing for testing, just to bring the game's built-in effects to the highest. The game comes with benchmark, which is not very ambitious in combat scenarios, but has overwhelmed the high-end graphics card.

Test Description: If crysis launched the video card crisis in the dx10 era, Metro 2033 is undoubtedly the graphics card killer in the dx11 era! Metro 2033 supports almost all of the new technologies that can be used at that time. It is like crysis in the face of the feelings of video cards. However, thanks to the accumulation of special effects and good optimization, crysis's amazing screen opened the gap with the dx9c game, and eventually earned enough attention; while the subway was not so lucky, although the picture is not bad, there are many bugs, attracting a lot of criticism.

Subway 2033, a poor sales, games forgotten but well-known, dx11 game of the wonderful. This game is a card advantage project, hd7970ge wins gtx770.

Dx11 games

Aliens. predator logs on to PC, x360, and PS3 at the same time. The PC version supports the subdivided surface (tessellation) and high-definition environment light shielding (hdao) in dx11) computing coloring machine post-processing, real shadow, and other technologies have received much attention and are one of the games vigorously promoted by AMD. However, such theme will inevitably make this work a lot of discord, violent and bloody scenes are inevitable! In November 2009, the publisher Sega once Mingzhi said that he would not give up the responsibility of e-entertainment product publishers to pass the review, because the game must maintain the core topic of the "Special-shaped war of tietong warriors, the screen, gameplay, and story line cannot be deviated.

 

The original AVP version does not support AA, but after the version is upgraded to Version 1.1, the msaa option appears in the dx11 enhancement effect. Of course, it also supports signs such as tessellation, hdao, and directcompute. This game does not require too much, so the author directly adjusts the special effects to the highest level for testing.

Test method: The game carries benchmark, in which the test screen is quite representative, it is a good embodiment of tessellation shaped body and hdao and other advanced effects, hope these effects can make the system play all its potential.

As an advantage project of the card, hd7970ge once again defeated gtx770 In the AVP test phase. After all, GTX 770 only uses the gk104 core.

 

Dx11 games: sniper List 2

Sniper elites is a sniper game product launched by reblion in 2005 against the background of World War II. Once released, it won the "best PC/host game" Award from the British Independent Game Developers Association, the "Sniper elite V2" is the continuation of this work. According to game developers, it continues to adhere to the style of game sneak sniper attacks. Compared with the first generation, it pays more attention to the post-shooting realism, "We promise that new games will be the most authentic sniper games during World War II. Not only in the weapons trajectory, but also in the tense atmosphere before shooting, will be very real ." Said Jason Kingsley, CEO of rebellion.

The overall picture of the game is quite good. Both the overall texture and the smoothness of the screen have reached a very high level, and the light source processing is also in place. At the same time, the game continues the design philosophy of the scenario of the first generation of excellence, for example, the broken walls, black smoke, and mysterious missile bases in the map of the city street battles left a deep impression on the author.

This game supports super sampling AA. After the special effects are fully enabled, the video card requirements have reached an astonishing level, and even surpassed the subway 2033, known as the graphics card killer, so we didn't enable super sampling in this test. We only started 4 xmsaa. Obviously, this game is still a card advantage project.

 

Hd7970ge and gtx770 who are more suitable for playing games?

The combat evaluation of radeon HD 7970ge and geforce GTX 770 graphics cards has come to an end since then, And the radeon HD 7970ge hero remains unchanged. Although new models and new faces are constantly on the market, the architecture technology belongs to the same generation of products. Hd7970 Ge is based on hd7970 through process optimization and firmware upgrade. In the face of these "elders", there is still no color available.

From the test results of the existing game, hd7970ge is proud of its 384bit bit width, which gives it a certain leading advantage in high quality and high resolution, if a high-end video card is not qualified for the severe challenge of high-resolution and high-effect effects, then its lifecycle and purchase value will be greatly reduced.

Looking forward to the future development of the game, among the three new hosts, Nintendo Wii U uses amd GPU, while Microsoft Xbox One and Sony PS4 use a brand new unified addressing Apu, why did NVIDIA achieve full dominance on the home gaming platform? You must know that they were once passionate about hosts. This time there was no trace of strength, or why?

Recently, NVIDIA finally broke its silence and explained why it was missing a new host. In an interview with media, Tony tamasi, senior vice president of NVIDIA content and technology, said: "I can ensure that, (Sony and NVIDIA) have been negotiating. Our final conclusion is that we don't want to make the purchase at the price that those guys are willing to pay ." "In the end, you have so many engineers who are capable of developing chips for Sony or Microsoft. If you want to develop chips for Sony or Microsoft, you may not be able to do the chips needed by other businesses. At least for Sony and NVIDIA, I mean PS4, AMD is involved, NVIDIA is not. I think we must look at it from the perspective of performance. This is obviously not related to technology ."

After talking so much, there is also a bit of truth, but this speech at this moment always gives people a feeling of being sour. After all, in addition to the interests of the current orders, it is even more important to optimize the support for future games. To put it back, is it so hard to pull a group of people to develop a new chip on nvidia scale?

Recently, NVIDIA's promotion and cooperation on PC games have been put on the limelight by AMD, especially the ghost movie 9. In the end, I'm afraid NVIDIA has not paid as much attention to the host game market or even the consumer video card market as AMD, but has switched more energy to tegra and mobile games. The importance of the three new game hosts to game developers is self-evident. From this perspective, I am afraid that the new cross-platform masterpiece amd graphics card will be optimized faster and more timely in the future. ■
