AMD and Server CPUs

Glenn Berry has an interesting post on why he’s seriously considering recommending AMD CPUs to people:

AMD claims a 15% Instructions Per Clock (IPC) increase between the desktop Zen+ and Zen 2 generations, and we are likely to see a similar increase between the previous AMD EPYC 7001 “Naples” and the AMD EPYC 7002 series processors.

So far, we don’t know the official base and turbo clock speeds, but there was a recent leak of partial specifications and pricing by a European retailer that listed max boost clock speeds of up to 3.4 GHz. We won’t know the actual single-threaded performance of these processors until they have been released and benchmarked by neutral third-party testers. I am optimistic that they will have higher single-threaded CPU performance than Intel Cascade Lake-SP processors.

I’ve always had a soft spot in my heart for AMD, so I’d love to see them come through with a serious competitor to Intel in the server space, for nostalgic reasons but also to make price more competitive and to make Intel get back on its game.

AMD vs Intel CPUs For Data Processing Jobs

Hariharan Iyer and Abhishek Srivastava run some tests against AWS’s new AMD-powered EC2 instances: Our summary findings from TPCDS benchmarks are as follows:– TPCDS queries are not as sensitive to local disk performance (and hence to EBS volume sizes)– r5 (Intel) instances are consistently faster than r5a (AMD) instances. However, the speedup depends on the […]
