Again in September AMD rounded out their Zen 4 server product line-up with the EPYC 8004 “Siena” processors which can be optimized for delivering glorious vitality effectivity with main performance-per-Watt and maximizing worth each for preliminary server prices and finally the TCO. These single-socket server chips are fairly fascinating for a variety of workloads kind the sting to networking and extra. In at present’s article are benchmarks of the top-end AMD EPYC 8534P and EPYC 8534PN 64-core server processors and exhibiting how they will tackle Intel Xeon Platinum “Sapphire Rapids” in uncooked efficiency and blow the competitors out of the water in the case of the unimaginable performance-per-Watt and worth.
The AMD EPYC 8534P is the top-end Siena OPN with 64 cores / 128 threads, 2.3GHz base clock, 3.1GHz increase clock, and a default TDP of 200 Watts. The EPYC 8634P additionally helps an adjustable TDP from 155 Watts to 225 Watts. The EPYC 8534PN because the NEBS-compliant providing is 64-cores too however with a 2.0GHz base clock whereas protecting to a 3.1GHz increase clock, which in flip permits it to have a default TDP of 175 Watts. The EPYC 8534P has an inventory value of $4950 USD and the EPYC 8534PN has an inventory value of $5450. Since launch I’ve discovered these EPYC 8004 sequence processors in-stock at just a few Web retailers for related costs.
As a reminder from the unique Siena launch article in addition to my EPYC 8324P(N) Linux benchmarks, the Siena processors make use of Zen 4C cores with all the Zen 4 frequent ISA options being supported like AVX-512, six channels of DDR5-4800 reminiscence, 96 lanes of PCI Categorical 5.0, and lots of the different components in frequent with Genoa and Bergamo.
For getting a really feel for the AMD EPYC 8534P(N) efficiency, I benchmarked these processors on AMD’s Cinnabar reference server in opposition to the Xeon Platinum 8468 because the closest Sapphire Rapids processor out there. The Xeon Platinum 8468 has 48 cores / 96 threads, as much as 8 channels of DDR5-4800 reminiscence, 2.1GHz base clock, 3.8GHz turbo frequency, and a 350 Watt TDP whereas carrying a price ticket of $7214 USD.
All of this benchmarking was carried out on Ubuntu 23.10 with the Linux 6.5 kernel and GCC 13.2 default compiler for offering a modern have a look at the Linux server efficiency with these contemporary packages forward of Ubuntu 24.04 LTS within the spring.
The AMD EPYC 8534P was examined at its default TDP and within the default efficiency determinism mode, at 155 Watts for its lowest cTDP in efficiency determinism mode, at its default TDP in energy determinism mode, and for top-power potential on the 225 Watts cTDP in energy determinism mode. The AMD EPYC 8534PN was examined at its default in efficiency determinism after which energy determinism modes. The PN processors would not have a configurable TDP.
The Intel Xeon Platinum 8468 in the meantime was examined at its default and utilizing eight channels of DDR5-4800 reminiscence after which re-tested when utilizing simply six channels of DDR5-4800 to match the reminiscence configuration of the AMD EPYC 8004 sequence.
The CPU energy consumption was monitored on a per-test foundation utilizing the PowerCap/RAPL Linux interfaces. The performance-per-dollar was additionally calculated primarily based upon the CPU listing pricing after which additionally including within the DDR5-4800 32GB RDIMMs at a value of $150 per DIMM, for serving to to issue within the influence of the six versus eight channel reminiscence testing. Because of AMD offering the EPYC 8534P and 8534PN evaluation samples for the Linux benchmarking on Phoronix.
