After four consecutive generations of evolution and iteration, AMD EPYC processors have become more powerful and luxuriant, and the Zen 4 family has been divided into four different sub-series.
The first product is the EPYC 9004 series standard version (codenamed Genoa), which is suitable for general computing, Zen 4 architecture, and up to 96 cores and 192 threads.
Then there is the EPYC 9004X series (codenamed Genoa-X) supported by 3D V-Cache stacked cache. For ultra-high-performance computing, the native 384MB plus stacked 768MB has a total cache capacity of up to 1152MB.
There is also the EPYC 9X74 series code-named Bergamo that continues the high-energy-efficiency Zen 4c core, which is specially optimized for cloud-native applications, with up to 128 cores and 256 threads.
Now, the Zen 4 EPYC family has finally completed the last piece of the puzzle: the Siena EPYC 8004 series is here!
The EPYC 8004 series is mainly targeted at intelligent edge applications such as retail, manufacturing, and telecommunications, as well as data center applications such as cloud services and storage, and can help customers create differentiated platforms with high energy efficiency.
The EPYC 8004 series and the EPYC 9X74 series both useSpecially designed energy-efficient Zen 4c architectureperformance and energy efficiency are more balanced, and system design also has considerable flexibility.
Using the same 5nm process, the area of the Zen 4 core plus the L2 cache is 3.84 square millimeters. After the Zen 4c core is streamlined, the area plus the L2 cache is only 2.48 square millimeters.Shrunk by a full 35%.
However, the Zen 4c core retains the exact same ISA instruction set, IPC performance, exactly the same technical characteristics, and there is no difference in the first and second level cache (64KB/1MB per core).It’s just that the level 3 cache is reduced (32MB per CCD)so for system and software applications, Zen 4 and Zen 4c are equivalent and no special adaptation is required.
The reason why the EPYC 8004 series uses completely different numbers is because its specifications and characteristics are quite different from the EPYC 9004/9004X/9X74 series:
The packaging interface is changed from SP5 to SP6 (the only interface of the fourth generation EPYC is different), single and dual channels are changed to only support single channel, the number of cores is reduced from 16-128 to 8-64 (up to 4 sets of CCD), DDR5 memory channel It has been halved from 12 to 6 (the frequency is still 4800MHz) and 3DS RDIMM is no longer supported. PCIe 5.0 lanes have been reduced from 128 to 96, and CXL 1.1+ link lanes have been reduced from 64 to 48.
The thermal design power consumption range has also been greatly reduced from 200-400W to 70-225W.
The AVX-512 instruction set, SMT multi-threading technology, Infinity Fabric cross-channel, Infinity Guard security protection, etc. are all retained intact.
Although the absolute performance is not as good as the EPYC 9004 series, the EPYC 8004 series also has its own strengths, that isUltra-high energy efficiency ratio, especially extremely high energy efficiency per unit cost.
There are many models in the EPYC 8004 series, 12 models in total, so it is necessary to understand the numbering rules:
The first digit represents the sequence, which is uniformly 8;
The second digit represents the number of cores, just like the EPYC 9004 series:0 8 cores, 1 16 cores, 2 24 cores, 3 32 cores, 4 48 cores, 5 64 cores;
The third digit represents the performance level, 1-8 is getting higher and higher (9 is reserved);
The fourth digit represents the generation, unified as 4.
There may also be one or two letter suffixes, whereP stands for single path, so all systems have it.
N stands for optimization for NEBSthe frequency and power consumption are lower, and the operating temperature range is wider, but the TDP is not adjustable.
The flagship model is EPYC 8534P, 64 cores and 128 threads, main frequency 2.3-3.1GHz, L3 cache 128MB, default TDP 200W, adjustable range 155-225W, temperature range 0℃ to 75℃.
EPYC 8534PNThe frequency is reduced to 2.0-3.1GHz, the default TDP is 175W, and the temperature range is -5℃ to 85℃.
besidesTwo models with 48 cores, two models with 32 cores, two models with 24 cores, two models with 16 cores, and two models with 8 coresI won’t introduce them one by one, the highest frequency is 3.0/3.1GHz.
AMD has extensive and in-depth product cooperation and ecological adaptation in the field of intelligent edge. Many OEM manufacturers and partners have released a number of unique systems and solutions that fully utilize the advantages of the EPYC 8004 series processors.It can meet customer library requirements over a wide range of power and temperature operating ranges and can be deployed in harsh physical environments such as dense data centers, urban telecom buildings, and factory floors.
for exampleDell PowerEdge C6615under the efficient form factor design, not only has higher performance, but also lower TCO (total cost of ownership), suitable for extended workloads such as containers and microservices.
Lenovo ThinkEdge SE455 V3with higher energy efficiency, can support next-generation AI applications at the edge, provide more powerful performance, higher storage and scalability, which is very important for supporting large-scale, high-demand edge AI workloads.
Ericsson’s Cloud RAN computing acceleration solutioncan easily manage huge traffic growth and use mobile networks in a more efficient and high-performance manner. The ultra-high core density and AVX-512 instruction set can also handle high-load site traffic with FDD and TDD frequency bands.
Supermicro also launched a new edge platform based on AMD EPYC 8004 series processorsbased on its H13 series of WIO servers, optimized to provide powerful performance and ultra-high energy efficiency for edge and telecom data centers.
The release of the Seina EPYC 8004 series finally completes the lineup of fourth-generation AMD EPYC processors. This is the first time in the history of EPYC that there is such a complete product line.
From general computing to ultra-high performance computing, from cloud services to edge computing, AMD EPYC now has targeted optimization solutions for various segments. Whether you need extreme performance or extreme energy efficiency, you can find the most suitable one. platform, and each series has far superior performance than its opponents.
With the release of the EPYC 8004 series, AMD can provide customers with excellent energy efficiency on single-socket systems to meet infrastructure needs with limited space and power consumption, further consolidating and expanding its leading position.
Intel Xeon is also accelerating, and will be divided into two groups for the first time next year, adding pure small-core designs, naturally in order to cope with the all-round layout of AMD EPYC.
But it is obvious that AMD EPYC has taken the lead, and its layout has become more comprehensive and in-depth. Moreover, the next generation “Turin” based on the Zen 5 architecture is also being prepared. It continues to have a rich segmented product line and does not give its opponents any A sense of opportunity.
