prefetching design, point-to-point topology, and 100nm below the production process, such as the latest technology, then DDR3 and DDR2 in the end have those different places? What are the performance improvements compared to DDR2 enthusiasts and players?
More flexible burst length
Because of the DDR3 8bit, the burst transmission cycle
provide 2Gbps (256mb/s) bandwidth, ddr4-3200 that is 51.2gb/s, higher than the ddr3-1866 of more than 70%. In the process of DDR development, it has always been to increase the data prefetch value as the main performance improvement means. But in the DDR4 era, the increase in data prefetching became more difficult, so the bank group design was introduced.
Wh
for DDR4 and DDR3 memory, a lot of computer players want to know the DDR4 and DDR3 which is good? Which is worth buying? The following is a test of DDR3 2400MHz memory and DDR4 2400MHz memory, their performance gap
productivity, more contacts to ensure the stability of signal transmission, but also to ensure that it and the motherboard card groove friction.
Capacity, the current mainstream DDR3 single capacity of about 8GB, and the use of 3DS stacking packaging technology DDR4 has the ability to upgrade capacity to 64GB, 8 times times the former. If your motherboard supports 4 channels, that 4*8GB memory is set enou
". So, can you say that Apple must be better than IBM? You can't. You have to see what type of processor it contains, how many cores it has, how much it is, how many L1 cache,l2 cache ..., how much memory and hard drives, how big the display resolution, what GPU, Nic speed, etc. "Configuration". Sometimes you have to look at the compatibility between the various
applications, but it can achieve good results in most applications. And with the development of hardware technology, the effect of dual-channel memory technology also began to highlight.
Three-channel memory technology, in fact, can be seen as the follow-up technology development of dual-channel memory technology. The Core i7 processor's three-channel memory technology, the highest support for ddr3-1600 m
separate 256KB L2 cache, and all cores can share the L3 cache of the highest 32MB.
New processor cache design;
Instruction Set
AVX2 instruction Set (or Haswell new instruction set, including vector aggregation scattering, bit processing, and support for FMA3)
Improve the operation performance of aes-in instruction;
Output input bus, processor socket, memory interface, chipset
Processors still use the QPI bus, one-way data transfer performance of 4.8gt/s, 5.2gt/s, 6.4gt/s and even 8.0gt/s
field "backward" pronoun, first of all brands in the flagship product launched 4K model, and then the 4K model to popularize to mainstream products and even entry level products, Of course, there are also a variety of "4K is more than Full HD" good publicity, a time consumers see dazzling, some do not know how to feel.
In fact, a lot of consumers will choose to buy 4K TV, simply because the store salesman told him that "4K TV
What's the difference between core i3 and i5 and i7? First, let's focus on the difference between i3 and i5:
Core Core i3 i5 i7 pin Difference
What is the difference between the core i3 and i5, the core i3 and i5 which is good?
The core i3 can be viewed as a further compact version of the Core i5, which will have a 32nm process version (R/D Clarkdale, based
recently there are plans to assemble a computer friend, asked a small series of such a question: DIY assembly computer What brand good? In fact, DIY computer machine does not have any brand problems, unless the brand desktop computer. However, think about it, DIY computer contains the CPU, graphics, motherboards, memory, hard disk, chassis, power supply and monitor hardware, each individual DIY hardware is
to tell you about the hard drive with the internal and the difference, in the computer play the role of what is respectively.
Hard disk and memory differences
When it comes to memory, many people easily confuse the memory of the computer with the memory card, in fact, the memory inside the computer and mobile phone running memory is the same, they
What is the meaning of Intel's launch of the DPDK development Kit? http://www.zhihu.com/question/27413080?sort=createdIntel DPDK-based packet processor, compared to the core network protocol stack based packet processor, where is the advantage and value?Based on the DPDK packet processing performance, whether it will be higher than the kernel-based protocol stack
What is the difference between the core i3 i5 i7?
Notebook PC Mobile Core I3i5i7 difference:
I3 dual core analog quad cores (ie four threads) without core frequency;
i5 Dual core simulation of the four cores (ie four threads) except the core frequency technology other technical specifications and i3 the same;
I7 Four nuclear simulation of the eight core (that is
What is the difference in the power consumption of mainstream graphics? more and more players are starting to focus on the power design of the graphics card. To this end, we have the current AMD and Nvidia mainstream graphics products have been tested to see the different products in the whole card power consumption, PCI-E slot to take electricity, video card external access to some of the different.

Focus on DIY hardware friends, AMD's newest a10-7890k flagship APU should not be unfamiliar, before the script house has brought many sets of a10-7890k related computer configuration recommended. And recently, a netizen asked small make up such a question: a10-7890k video card equivalent to what is the performance of the graphics card? For this problem, small compilation teaches everybody a small skill.
Before buying a computer, we must understand the relevant configuration of the computer, memory, graphics, frequency, etc., but you know what the working frequency of computer memory? The following look at the small series to introduce you to the introduction bar.
Memory frequency is the same as CPU frequency, is used to represent the speed of memory, it represe
I have been chatting with several people recently and everyone has their own views on being active. In addition, many people who are unfamiliar with terms of analysis due to some standard issues have mixed up a lot of information such as being active and retaining. later I found that this is a very real problem. In my opinion, none of the problems have become problems. Therefore, I would like to talk about active things here to help more developers wh
