Intel Xeon 6766E/6780E Sierra Forest vs. Ampere Altra Performance & Power Efficiency
With the launch day review of the Intel Xeon 6766E and Xeon 6780E 'Sierra Forest' processors the focus was on looking at the performance and power efficiency compared to prior Intel Xeon generations as well as the AMD EPYC competition.
Ampere Altra supports eight channels of DDR4-3200 ECC memory, 1MB of L2 cache per core, 128 lanes of PCIe Gen4, and the processor is manufactured on a TSMC 7nm FinFET process. The Xeon 6780E/6766E have 16 more cores (+12.5%) than the Ampere Altra Max M128 but also with a much higher TDP and much faster DDR5-6400 memory support... With AmpereOne is DDR5 and PCIe Gen 5 albeit no hardware for testing. Besides the Ampere Altra Max M128-30 vs. Intel Xeon 6780E/6766E benchmarks, the AMD EPYC single socket results are also shown in this article for reference.
