At the same time, a large number of them have been added.The serverData center, cloud and other related features, interconnection, memory, security, power supply and so on have been strengthened accordingly.
The second generation Xiaolong also uses chiplet chip design. The basic unit is CCX. Each CCX contains four cores (eight threads). Then two CCX make up a CCD, that is, a CPU Die, which contains eight cores (16 threads). Then each processor contains more than one CPU Die, and up to eight make up 64 cores (128 threads).
Detailed specifications are different. Refer to the top article on the home page, we can see how the performance of the second generation Xiaolong processors is. Phoronix has just published the performance tests of EPYC 7742 processors on single, double and EPYC 7502. The specifications of the two processors are as follows:
EPYC 7742 ≤ 64 core 128 threads, reference frequency 2.25GHz, acceleration frequency 3.4GHz, TDP 225W, 256MB L 3 cache, 1000 wholesale price $6950.
EPYC 750232 core 64 threads, reference frequency 2.50GHz, acceleration frequency 3.3GHz, TDP 180W, 128MB L3 cache, 1000 wholesale price $2600.
Contrast processors exceptAMDIn addition to the first generation EPYC Xiaolong 32 core processor, there are Xeon Platinum 8280 and Xeon Gold 6138, two products of friends, the specifications are as follows:
Xeon Gold 6138 × 20 core 40 threads, benchmark frequency 2.0GHz, acceleration frequency 3.7GHz, TDP 125W, 27.5MB L 3 cache, 1000 wholesale price $2612 to $2618.
Xeon Platinum 8280 ≤ 28 core 56 threads, reference frequency 2.7 GHz, acceleration frequency 4 GHz, TDP 205W, 38.5 MB L 3 cache, 1000 wholesale price $10009.
The following performance tests are all for servers and data centers. They are different from the common desktop X86 processors. There is no comparability. They are not explained one by one. What we are interested in is comparing AMD with other desktop X86 processors.IntelThe results of both sides, pay attention to some of the lower the better.
In summary, AMD has been able to roll Intel processors in performance for 50 years. Although this performance roll is largely achieved by 64 cores vs. 28 cores, AMD is a big leader in performance, advanced technology support and expansion when the price is less than 70% and the number of cores is more than double. Better than their rivals, what are the unsatisfactory buyers in the data center market?
