The current differences between INTEL and AMD CPUs

The current differences between INTEL and AMD CPUs, as well as the differences in performance and efficiency caused by the differences, are as follows, for reference only:

1. From the perspective of monocrystalline silicon process: INTEL: 0.09 (lower cost, increase the number of transistors), AMD: 0.13 (cost higher than 0.09), so after both reducing the price by the same proportion, INTEL is still Make money, and at least AMD will not make too much money, and it may still make money (loss), although the market share has increased, which has led to the recent AMD lawsuit

2. From the assembly line: INTEL: Level 31 (can be upgraded to a higher frequency, but will bring greater heat generation: for example, P4-670 exceeds 7.4G, but liquid nitrogen is used to dissipate heat, and it is easy to cause instruction execution The efficiency is low, so hyper-threading is used to make up for it); AMD: level 20 (the efficiency of instruction execution is better than level 31, but the frequency increase is limited and the heat generation is relatively low. Efficiency and frequency are two different development directions. Mainly It depends on the user’s choice)

3. Cache: INTEL: Level 1 16K, Level 2 1M-2M (integer operation and game performance are not as fast as AMD (there is another main reason at play, which will be discussed later), but for network and multimedia (floating point operations) applications Better than opponents

AMD: Level 1: 128K, Level 2: 512K (fast integer operations, good game performance, but slightly inferior to multimedia applications)

4. The memory management rack is sufficient. : INTEL's memory management rack is still managed by the traditional north-south bridge method on the motherboard (which causes a large data transmission delay between the CPU and the memory, and the game execution effect is not as good as AMD's, but it will reduce the cost of future upgrades. Reduced) AMD is an integrated memory controller inside the CPU (which reduces the delay in data transmission between the CPU and memory), (which plays a considerable role in improving game performance, which is also the main reason mentioned earlier, and also makes up for the fact that level 2 only has 512K It is insufficient for multimedia applications, but it increases the cost of future upgrades: if you want to upgrade, you have to replace the CPU, memory and motherboard)

5.

Instruction set INTEL: MMX, SSE, SSE2, SSE3, EM64T

(Most games and software are based on INTEL instructions and are optimized for INTEL, but 64-bit instructions are compatible with the new 64-bit system shortcomings, so recently it has to be compatible with AMD's X86-64 instructions, and the CPU step value has also changed from E0 to G1) AMD: 3DNOW, MMX, SSE, SSE2, SSE3, There are 2 instructions missing, but this is not a big problem, because those 2 instructions are specifically for INTEL Hyper-Threading Technology. It doesn’t matter if they are not available. AMD does not support Hyper-Threading Technology anyway, because AMD’s 64-bit technology is derived from DEC’s Alpha technology. (one of the 64-bit technologies), coupled with AMD's own two developments, led to the rapid emergence of 64-bit technology in the civilian market, and Microsoft's 64-bit system had to be developed based on AMD's X86-64 bit (who is called AMD First launch 64-bit for civilian use). In order to eliminate the problem of 64-bit WINDOWS compatibility as soon as possible, INTEL was also forced to become compatible with AMD's 64-bit instructions (it is not that INTEL does not have the technology to develop 64-bit, but it is due to its market strategy that its They were very passive and missed the best opportunity to launch 64-bit, which gave AMD the upper hand in terms of 64-bit. Who said these two companies would have to look at Microsoft's face in the end? From this point of view, they have not yet fully reached the goal. The status of market monopoly---hardware manufacturers still have to look at the faces of software giants. How sad! Determined by the scope of application), not simply by price. I don’t agree with the so-called poor people who use AMD (my buddy’s current personal assets are more than 5 million, which is considered a bit rich, right?! But The computer he installed uses AMD 3000. Why? Because he is not a computer enthusiast and does not know much about computers. He personally thinks that it is enough, but he must also keep up with the trend. If he is an enthusiast It’s hard to say whether to buy INTEL’s XEON or AMD’s Opteron CPU. Because INTEL felt the pressure from AMD, the company made major changes in its development strategy (from blindly pursuing frequency to pursuing performance, it also had to Abandoning the myth of Moore's Law created by INTEL itself, and turning to the improvement of CPU performance, the CPU has come to a small end at the frequency of 3.8G, making the goal of 10G come to nothing; more reliable news: INTEL's future CPU racks will be based on current mobile CPU technology, and have proposed the concept of cost-effectiveness (rather than cost-effectiveness) and have recently successfully developed a sample, which will be three times that of the current P4 in terms of performance - 5 times, and the power consumption ranges from 5W of notebook CPU to 35W of desktop CPU to 65W of server CPU. The core will be dual core or 4 core. The front side bus is: 533MHZ, 667MHZ, 800MHZ, 1066MHZ; there is no more super Threading technology (because it is no longer necessary. The emergence of hyper-threading technology is mainly to make up for the inefficiency caused by too long pipelines. The new INTEL CPU will no longer use a 31-level pipeline, and may only have less than 20 levels or even lower) , the frequency will not exceed the existing frequency (this means that 3.8G will be the highest frequency of INTEL now and even in the future). In the upcoming big competition in 2007 (INTEL and AMD), there will be a showdown, who will win then? It will be clear who loses, who is good and who is bad, and whose price/performance ratio is higher. To be honest, I am a little worried about AMD (AMD has recently stated that it will not change the existing CPU frame), but it is more for us Chinese. Godson is anxious! I still believe that sentence: time will tell everything! Which product will consumers look forward to most? I believe it will appear in the near future!
