#AMD #EPYC Turin 128 Core Comparison: #EPYC9755 "#Zen5" and the #EPYC9745 "#Zen5C" at 400W and 320W TDP
Overall the AMD EPYC 9745 offered good performance relative to the EPYC 9755 with its full Zen 5 cores and higher TDP while offering quite a nice lead in performance-per-Watt across the many workloads tested. The EPYC 9745 is great choice for those concerned about maximizing the power efficiency of your EPYC 9005 series server build and/or limited to a maximum 400W TDP

AMD EPYC Turin 128 Core Comparison: EPYC 9745 "Zen 5C" vs. EPYC 9755 "Zen 5" Review

The AMD EPYC 9755 128-core Zen 5 server processor has been benchmarked a lot at Phoronix since the EPYC 9005 'Turin' launch as their top-end Zen 5 server processor with 'full fat' cores compared to the denser Zen 5C cores that extend up to the EPYC 9965 at 192 cores.

#Intel #Xeon #6980P vs. #AMD #EPYC9755 128-Core Showdown With The Latest #Linux Software For EOY2025 Review
As #2025 comes to an end, today's article is a fresh look at these latest-generation Intel Xeon and AMD #EPYC processors while using an up-to-date Linux software stack compared to the prior launch day testing last year.
A lot of dominating results by the AMD EPYC 9755 compared to the #Xeon6980P flagship at the same 128 core / 256 thread count per socket.

Intel Xeon 6980P vs. AMD EPYC 9755 128-Core Showdown With The Latest Linux Software For EOY2025 Review

Since receiving the Gigabyte R284-A92-AAL1 a while back as a Xeon 6900 series 2U server platform to replace the failed Intel AvenueCity reference server, I have been getting caught-up in fresh Xeon 6980P Granite Rapids benchmarks with the latest software updates over the past year.

#AMD 128-core #Zen5-based #EPYC9755 'Turin' tested: 2X faster than 128-core predecessor compared to the #Zen4c #EPYC 9654 'Bergamo' in #7Zip
Considering microarchitectural improvements of Zen 5 over Zen 4, higher clocks, and a larger cache, the EPYC 9755 can indeed be two times faster than the EPYC 9654 in many workloads, especially because being Zen 5-based, it is aimed at workloads sensitive to single-thread performance, unlike the Zen 4c-based CPU.

New #Zen5 128-core #EPYC #CPU weilds 512MB of #L3 cache
The highest capacity to date for non-3D V-Cache parts.
The #EPYC9755 sports 128 cores, 256 threads, and a peak turbo clock of 4.1GHz.
If these new specs are not fabricated, it suggests that AMD will increase L3 cache sizes for its Zen 5-based EPYC processors. Compared to its predecessors, the EPYC 9755 has 33% more L3 cache than the 96-core EPYC 9654, which has 384MB of L3 cache spread across 12 CCDs.
