AMD EPYC 7002, even in a single-socket configuration, can handle 24x NVMe SSDs with 96x PCIe Gen3 lanes at full speed (theoretically even only using x48 PCIe Gen4 lanes with appropriate PCIe switches.) It still can place one or two PCIe Gen3 NICs in a Gen3-only system which is only a 3:1 oversubscription, half of Intel’s
This is the important part to remember: performance per watt. Intel absolutely hammered AMD on this in previous generations of server and client products. Now, the tables have turned, especially at the high-end. AVX-512 is a particular feature that absolutely pushes Intel Xeon power consumption. It seems AMD’s decision to omit AVX-512 in this generation means that it is more power-efficient. In every dual-socket test, we are seeing the AMD EPYC 7742 out-perform the dual Intel Xeon Platinum 8280 configuration sometimes by ~2x, and yet the maximum power is lower.
Frankly, this completely breaks corporate IT purchasing cycles. Consolidating 6-8 sockets into 1 has an immense VMware licensing impact. Further, we are using about one-quarter of the power even with some of the efficiencies we gained by going 2U 4-node.
The TDP of the AMD EPYC 7702P is higher than the Intel Xeon E5-2630 V4’s, but when you are replacing 6-8 sockets to 1 socket, the power savings are absolutely immense. We have not seen 6:1 consolidation ratios in under 2.5 years of technology advancement happen in the industry.
This bit is important:
"Customers need to adopt AMD EPYC. To our readers, it is important when you get a quote to at minimum quote an AMD EPYC alternative on every order. More important, follow through and buy ones where Intel is not competitive
. If AMD EPYC 7002, with a massive core count, memory bandwidth, PCIe generation and lane count, power consumption, and pricing advantage cannot take significant share, we are basically done. If AMD does not gain enormous share with this much of a lead
, and easy compatibility, Intel officially has a monopoly on the market and companies like Ampere and Marvell should shut down their Arm projects. If AMD does not gain significant share, there is no merit to having a wholistically better product than Intel."
