AMD reveals Epyc 9004: approximately 96 cores for around $12,000

In context: AMD took the audience on a roller rollercoaster trip as it revealed the 4th generation of Epyc information center processors at a live occasion recently. The speakers tossed number after number at the audience the entire method through, so buckle up as we break them down.

We ought to begin with the name of the series: 9004, following on from 7003, 7002, and7001 Why the 9? Unsure, however the routing 4 is a referral to both the generation and the architecture, Zen 4. The codename for the series is/was Genoa, continuing AMD’s custom of calling Epyc series after Italian cities, which in the past has actually consisted of Milan, Rome, and Naples

AMD has actually likewise established an affinity for the number 5. 8 channels of DDR4 have actually ended up being twelve channels of DDR5-4800(for approximately 6 TB per socket), and 128 lanes of PCIe 4.0 have actually paved the way to 128 lanes of PCIe 5.0 and 64 lanes of CXL 1.1+. The series likewise changes from TSMC 7nm to 5nm and embraces a brand-new socket, called SP5 (LGA 6096). And last but not least, AMD lastly signs up with Intel with assistance for the AVX-512 direction set.

All costs are for orders of 1000 systems.

AMD revealed 18 designs in overall (arranged above and listed below). They cover from 16 cores to 96 and have suffixes that signify their type: F, for quick and ineffective; P, for single-socket just; and no suffix, for typical and dual-socket. AMD shared much more comprehensive specifications than we might fit here, things like cache capabilities and configurable TDPs, so if you’re interested, begin with AMD’s information sheet and after that have a look at their paperwork page for Genoa.

AMD is declaring that Zen 4 has a ~14% IPC benefit over Zen 3 in server circumstances. It states the uplift is attributable to a doubling of the L2 cache capability to 1 MB and enhancements in the front end, branch forecast, load/store, and the execution engine. Genoa likewise more than doubles the theoretical memory bandwidth of each socket from 205 GB/s to 461 GB/s.

Added with the somewhat greater clock speed and the significantly increased core count of the 9654, the brand-new flagship is 1.9 x faster than the previous one, according to AMD, which utilized the Java-based SPECjbb 2015 tool as a standard. Obviously, the 9654 costs $11,805, and the 64- core 7763 costs a 3rd less at $7,890, however the Genoa part is still much better worth.

If you’re not offered on AMD’s cherry-picked numbers, Phoronix has a detailed launch day evaluation of the 9654 and the9554 It’s worth a read, however the bottom line states that the brand-new Epyc parts triumph in every multi-core criteria and land in the middle of the Intel Xeon parts in light single-threaded work. Genoa’s flagships simply “more” in every method: more efficiency, more power usage, and more pricey. They’re so quick that they’re still more effective and much better worth than the competitors.
