Intel is firing back at AMD CEO Lisa Su's Computex claims that the company's upcoming 7nm EPYC Rome data center processors are twice as fast as Intel's Xeon Scalable 8280 processors in a popular benchmark. But Intel says that AMD didn't configure its Intel test system correctly, and also didn't use the most relevant processors for comparison testing. Now Team Blue has released benchmarks to back its claims.
But Intel doesn't want to just be more competitive. It wants to prove that it will continue to lead even after AMD's 7nm Rome processors come to market. To that effect, Intel also included test results with its Xeon Platinum 9000-series (Cascade Lake-AP) that come armed with as many as 56 cores, 112 threads, and 12 memory channels crammed into a package that dissipates up to 400W. These new behemoths, which are essentially two Skylake-SP CPUs in a single socket, only come in OEM servers, so they aren't available on their own like AMD's Rome chips will be.
AMD did use a different compiler for its EPYC setup than it did for the Intel system, but that's expected. Intel's tuning did expose greater performance from its chips than AMD did, but that appears to be because AMD didn't use the optimizations. Intel's optimizations are available publicly on its website, meaning that AMD either wasn't aware of the optimizations or chose not to use them. Aside from the lack of optimizing the competitors' platform, which may be unintentional, it doesn't appear that AMD went out of the way to skew its test results.
