CPU four generation and three generations difference contrast

Intel launched its four-generation Haswell processor in the second half of this year, with high, medium and low-end products listed today, as the new generation of Haswell processors cost more than the three-generation Ivy Bridge processors, and the Haswell platform needs to match the All-new 8-series motherboards. The price is also more expensive. Therefore, recently found a lot of DIY installed users entangled in the CPU four generations and three generations do not know which to choose?

The four-generation CPU used a new Haswell architecture, based on the updated 22nm process (the same is the 22nm process of the three generations of CPU, but only four generations for further optimization, so it can be said to be better), while the CPU also uses a new LGA1150 interface, need to carry a brand-new 8 series motherboard.

Four-generation Haswell processor belongs to Ivy Bridge upgrade, first of all, in performance, the four-generation Haswell processor is certainly better than the three-generation Ivy Bridge processor, the current four generations compared to the three generations of the same level of CPU price difference about how about hundred yuan, Another 8 series motherboard than the 7 series motherboard expensive about is about hundred yuan, so the most tangled is the price, if not care about so expensive one or two yuan, directly select the latest four-generation CPU can. We are more than a lot of spending one hundred or two hundred yuan is worth it, the following we have four generations of CPU and three-generation performance comparison to see.

　　One or four generation vs. three-generation CPU performance Comparison

With our previous four generations and three-generation CPU performance evaluations, it is known that the quad-generation Haswell architecture processor does not improve CPU performance compared to the three-generation Ivy Bridge architecture processors, in general, around 7%-10%, This is mainly relying on the Haswell architecture to significantly optimize the results of cache performance, because the three-generation Ivy Bridge processor has been very mature in the day-to-day use and game has been very good, so in the CPU performance Fang min, four generations and three generations of CPU in the daily use, we basically do not feel the gap, Only through some professional software testing can be known.

Also worth mentioning is the four generation Haswell processor new AVX2 instruction set, floating-point performance doubled, the video codec should have a relatively large acceleration, the current relevant software applications are relatively few, need to wait for a while to let software developers to do the corresponding optimization, this is a little difference.

　　Performance comparison between two or four generations and three-generation CPU core Graphics

The biggest bright spot of the quad-generation Haswell processor is that it dramatically improves the performance of the core graphics card, which is certainly a huge advantage for an integrated installed user who does not intend to buy a stand-alone video card. Through our previous four generations and the three-generation CPU comparison evaluation can be seen, Haswell desktop model integration GT2 level core graphics, such as the four-generation CPU built-in HD Graphics 4600 core graphics performance compared to the three-generation HD Graphics 4000 core graphics upgrade of about 30%. Three generations of IVB processors can barely play some of the medium and small mainstream games before consolidating their computers, while the four-generation Haswell processor integration computer has been able to play most mainstream games.

So it's easy to get a conclusion here, if the computer performance requirements are not very high, just play CF, World of Warcraft, Hero League and other popular games, then the four-generation CPU built-in core graphics can meet the needs, without the purchase of independent graphics, for this part of the user, the four-generation CPU is undoubtedly the first choice.

Many other mainstream installed users will choose a separate video card, after all, you have to play all kinds of games, play more open, with a mainstream independent graphics is indispensable for the users with independent graphics, three or four generation of CPU in the performance gap is very small, if pay attention to cost-effective, the current three generations of CPU is a good choice.

　　Three or four generation vs. three-generation CPU power consumption comparison

The Daicouri of the TDP appears to have been elevated from 77W to 84W in the previous generation, but because Haswell integrated full voltage controller, the relatively aggressive energy-saving scheme (which is significantly reduced standby power consumption) can be used, and the actual platform power consumption is not high. So in terms of power consumption, the difference between the two is small, users need not tangle.

　　Four or four generation and three-generation CPU motherboard selection

Four-generation CPU needs to carry 8 series motherboard, mainly has the entry-level H81, the low-end mainstream B85, the high-end H87 as well as the high-end overclocking motherboard Z87;

And the three-generation CPU is carrying 7 series, mainly have entry-level H61, middle and low-end mainstream B75, high-end H77 and high-end overclocking motherboard Z77;

The 8 Series motherboard and the 7 Series motherboard are mainly the number difference of the expansion interface, overall, the 8 Series motherboard expansion interface to enrich some, while the 7 series motherboard, although less, but the use of fully enough, the two are basically no difference in performance, the price of 8 series of new motherboards compared to 7 series expensive 50-100 yuan.

Through the above CPU four generation and three generations of differences in contrast, we can see that the four-generation CPU and three generations of CPUs are mainly in the core graphics card has the biggest difference, for the integration of installed users, in spite of your hundred yuan, but the four-generation CPU by upgrading 30% of the core graphics performance, it And for a single user, you can be based on cost-effective or new platform to consider, in theory, a difference of one hundred or two hundred yuan, the gap is not large, we generally recommend the election of the old, but if it is to pay attention to cost-effective and based on the difference between the two dominant, then three generations of CPU is also a good choice, how to choose It depends on the views of the people.
