Benchmark Results for AMD Ryzen 9 7950X Processor System using STAC-N1
This article analyzes the Strategic Technology Analysis Center (STAC) and the STAC-N1 benchmark, explains why AMD Ryzen 9 CPUs in servers are perfect for crucial financial workloads, and then goes on to detail the systems that were evaluated and their findings.
Concerning STAC and the STAC-N1 Standard
Leading financial institutions and technology providers form the STAC Benchmark Council, which STAC sponsors and which establishes standards for evaluating financial technology. To assess how network stacks function in a simulated market data environment, the STAC Benchmark Council developed the STAC-N1 benchmarks.
The STAC-N1 benchmark does not need additional applications like middleware or exchange feed handlers since it leverages standard financial services workloads across many network APIs in a vendor-neutral way.
The low-latency capabilities of a system are shown by the STAC-N1 findings. The Financial Services Industry (FSI), which depends on high-frequency trading applications where even milliseconds of delay may affect earnings, finds this especially important. The STAC-N1 benchmark yields comprehensive latency analysis, throughput, CPU, and memory information, and offers a degree of automated testing and analysis.
Processors from AMD Ryzen TM 9 7950X Are Perfect for the Financial Services Sector
Because of capabilities like these, AMD Ryzen 9 7950X processors, which are based on the “Zen 4” architecture, provide record performance for demanding applications.
- Each CPU may have up to 16 physical cores and 32 threads.
- CPU boost clock maximum of 5.7 GHz
- Support for DDR5-5200 MT/s DRAM up to 128GB
- A pair of PCIe 5.0 x16 (FHHL) slots (16/NA or 8/8).
The capabilities provide the high performance that makes AMD Ryzen 9 7950X processors perfect for the HFT use-case, where a few microseconds of extra speed may result in millions of dollars in profit, as well as for the FSI industry.
Examination Setup
The following setup was examined by STAC, and the findings were released in the STAC Report (SUT ID AMD231005) for STAC-N1:
Two 1P Supermicro Mainstream A+ Server AS -2015A-TR platforms are used.
CPU: 4.5GHz (5.7GHz boost) 16-core AMD Ryzen 7950X with 64MiB L3 cache(Source: )
Memory: 2 × 4800 MT/s 32GiB DDR5 DIMMs
Networking: AMD Xilinx Open Onload 8.1.1.17 is used with AMD Xilinx Xtreme Scale X2522-25G-PLUS25 GbE adapters.
Interconnect: A single switchless, point-to-point 25GbE cross-connect cable linked the two servers, disabling Forward Error Correction (FEC).
Red Hat Enterprise Linux 9.2 is the OS.
AMD Ryzen 9 Processors Keep Accumulating
Comparing the setup mentioned above to all publicly released STAC-N1 results that have used UDP so far, the configuration showed superior UDP performance with the following characteristics:
For the base rate of 100k messages per second, the lowest mean, median, 99 percentile, and highest latency (STAC.N1.β1.PINGPONG.LAT1)
A maximum throughput of 1.6 million messages per second was the greatest that was tested (STAC.N1.β1.PINGPONG.TPUT1).
At the highest measured rate (STAC.N1.β1.PINGPONG.LAT2), the lowest mean (1.8µs), median, 99 percentile, and maximum (7µs) SupplyToReceive latency were recorded.
At the highest rate tested, the lowest mean, median, 99 percentile, and maximum Send To Receive latency were found (STAC.N1.β1.PINGPONG.LAT3)
On October 19, 2023, these findings were presented at the STAC Summit in New York. The results summary is available for viewing here. More information on these outstanding outcomes is available to Premium STAC members.
Less than half of an AMD Ryzen 7950X processor’s cores are needed for the STAC-N1 test, freeing up the other cores for the simultaneous execution of another program in a production setting.
