AMD is a family of three generations Dacentrurus while extending in all directions: up there first mainstream 16 core 32 thread Dacentrurus 9 3950X, and down is more mainstream, more cost-effective Dacentrurus 5 3500X / 3500, and in the end It will also appear still 12 core 24 thread but the thermal design power of only 65W of Dacentrurus 93900.
Today, Dacentrurus 5 3500X official shelves starting in Jingdong, the price as long as 1099 yuan, aimed against the Intel Core star level i5-9400F, 100 dollars cheaper than the latter.
RuiLong 5 3500X still based 7nm technology and architecture Zen 2 , 15% IPC performance, throughput 256 double floating point, TAGE branch predictors, double the bandwidth 512 Infinity Fabric, 4K OpCache double capacity, PCIe 4.0 bus like everything bonus .
6 core thread 6, three generations of the family for the first time Dacentrurus does not support multi-threading, frequency of the reference to 3.6GHz, the highest speed up to 4.1GHz, integrated 3MB cache, 32MB level three cache, dual-channel memory support DDR4-3200, the interface AM4 .
Thermal design power of 65W, the internal still advanced brazing a heat sink material, the heat sink comes original ghost.
Performance, the official nominal popular games in high-definition full effects, is stable over 90FPS , smooth chicken is no problem.
Follow-up there will be a sharp dragon 53500 , specifications and Dacentrurus 5 3500X basically the same, but the main cache capacity cut and a half, the price is bound under thousand dollars.
Speaking for the first time AMD mainstream desktop market to build 16 core 32 thread Cheng Ruilong 9 3950X, it has been postponed to November, the official is to further adjust the frequency and performance, has reached the players expected.
Although have to wait more than a month, but Dacentrurus 9 3950X has appeared in the list of commodities dealer, it is interesting boxed product number (OPN PIB) is displayed as 100-100000051WOF, WOF three letters at the end means no original fan (whitout fan).
We know that three generations Dacentrurus in every model of AMD will be accompanied by the original radiator, radiator various levels are not the same, the higher the better model, but on the AMD website Dacentrurus boxed number 9 3950X 100 -100000051BOX, clearly marked and comes with the most high-end ghost Prism RGB radiator.
This radiator to deal with thermal design power of 105W Dacentrurus 9 3950X is enough, but for such a top-16 core products, there will certainly be a lot of players hoping to tap its potential as much as possible, power consumption and heat inevitably far super indicators, which requires better and even water-cooled air-cooled.
Obviously, for these players, it would be wasteful to buy the original radiator, so AMD specially prepared two versions, but with no hope of release radiator, can be cheaper.
Dacentrurus 9 3950X official price of $ 749, the National Bank is expected to 5999 yuan. Sale price of a Hong Kong retailer gives the 6380 Hong Kong dollars, or about 5800 yuan.
However, you can imagine AMD big price increases it?
In the past to lead the price trend is Intel, Intel just released last nine generation Core Duo processor, the Core i-9900K once the price to $ 600, will be priced at around $ 500 long-term, low-cost history of these two days down to $ 475 a.
Now the situation is different, come full circle, this year's turn to lead the AMD processor prices, Dacentrurus 9 3900X although only once flagship 7nm Dacentrurus of 3000 AMD, but Dacentrurus 9 3950X postponed today, it is still one of the best choice, the starting price of $ 499 can buy 12 core 24 thread processors game .
Unfortunately Dacentrurus supply 9 3900X has been not to force, on the market two months is still buying in the past two days the price has gone crazy, whether it is the United States and Asia or the US egg prices are approaching $ 800, and more than $ 800 the price is a lot .
Compared with the listed price of $ 499, a $ 800 Dacentrurus 9 3900X is equivalent to a premium of 60%, this increase is even higher than last year's increase of Core i9-9900K, it is staggering.
Let me say the data center sparkly Xiao Long Bar.
Since 2017 Zen architecture with high-performance processor to return to the CPU market, AMD's X86 share rising, the previous two generations of 14nm, 12nm processor is the warm-up, this year's sharp 7nm Long and Xiao Long is the main character, this time AMD in the performance to catch up.
On the server CPU market, AMD's share had even worse, only 1% higher than the minimum desktop, but from Naples 32 64 nuclear core to this year's Rome, EPYC processor this time not only in the number of cores continue to outperform, but also to chase performance coming up, AMD officials said EPYC 7002 series has created more than 80 world record time of publication.
For performance EPYC 7002 series processor, previously we had multiple tests, the Japanese manufacturer recently HPC and dual-processor test EPYC 7602 non-flagship models, it is also threaded 64-core 128, but the reference frequency is 2.0GHz, to accelerate 2.235GHz, TDP 200W, than the flagship EPYC low fundamental frequency of 7742 0.25GHz.
Of course, compared to the processor is not top models, Intel Xeon here is platinum 8270,26 core 52 thread, frequency 2.7GHz, there is the previous generation of Naples EPYC 7551,32 core processor 2.0GHz.

Several tests, it can be seen compared to significantly enhance the performance of EPYC 7551 Dual Dual EPYC 7702, the former HPL performance is 2.7 times more than the latter, far more than the number of cores change means that single-core performance is also increased dramatically .
Compared with the Intel side of the 26-core processor, HPL leading performance is not much, but mention this is because the original problem AVX512 instruction set, AMD processor does not support this instruction set, but still by the number of core strengths violence improve performance.
In short, the EPYC 7002 series processors, AMD can be seen a major increase in the number of CPU cores, and single-core performance is also promoted. As for competition with other vendors, although the lack addition AVX512 instruction set, but violence stack core strategy is very effective and is achieved in 20% of cases cheaper CPU.
