AMD Bergamo & Genoa-X EPYC Server CPUs Crush The Competition With Sheer Performance & Efficiency Dominance
wccftech.com
AMD's EPYC Bergamo and Genoa-X CPUs have been praised for their exceptional performance and efficiency. The Genoa-X chips offer up to 96 cores and 1.1 GB of L3 cache, while Bergamo boasts up to 128 Zen 4C cores. Both CPUs outperform Intel's Sapphire Rapids Xeon CPU and offer significant power efficiency improvements. AMD's dominance in the server market is expected to continue with the upcoming Sierra Forrest and Siena lineup.
Running The AMD EPYC 9754 CPUs With A 320W cTDP To Enhance Power Efficiency Review
www.phoronix.com
The AMD EPYC 9754 CPUs can be run with a 320W cTDP to enhance power efficiency. Lowering the TDP to 320W delivers similar performance across workloads while reducing CPU power consumption. The EPYC 9754 2P at 320W runs at around 99% the performance of the default 360W configuration, with up to 5% lower power consumption. This option is beneficial for maximizing power efficiency in server environments. Additionally, switching to a 400W TDP increases performance by about 6% with a 10% power increase. AMD's cTDP options allow for fine-tuning servers for maximum performance or squeezing out the most possible performance.
AMD Bergamo And Genoa-X Performance Review: EPYC Chips For Big Iron Workloads - Page 2

The review compares the performance of AMD's Bergamo and Genoa-X EPYC chips for big iron workloads. The tests were conducted using Ubuntu Server 22.04 with the 5.15.0-76-generic Linux kernel. The AMD EPYC 9754 performed well in Coremark, 7-Zip decompression, and Blender 3D rendering. The EPYC 9684X excelled in 7-Zip compression and Linux kernel compilation. In terms of video encoding, the EPYC 9654 performed best in 4K x264 encoding, while the EPYC 9754 lagged behind. For database processing, the Bergamo and Genoa-X chips outperformed Intel's offerings in both read-only and read-write workloads. However, in web server benchmarks, Intel's chips performed better, particularly in NGINX. Intel's accelerators also provided an advantage in hashing algorithms.
