AMD Rome Second Generation EPYC Review: 2x 64-core Benchmarked

From the conclusion:

Due to bad luck and timing issues we have not been able to test the latest Intel and AMD servers CPU in our most demanding workloads. However, the metrics we were able to perform shows that AMD is offering a product that pushes out Intel for performance and steals the show for performance-per-dollar.

For those with little time: at the high end with socketed x86 CPUs, AMD offers you up to 50 to 100% higher performance while offering at a 40% lower price. Unless you go for the low end server CPUs, there is no contest: AMD offers much better performance for a much lower price than Intel, with more memory channels and over 2x the number of PCIe lanes. These are also PCIe 4.0 lanes. What if you want to [have] more than 2 TB of RAM in your dual socket server? The discount in favor of AMD just became 50%.

[...] So has AMD done the unthinkable? Beaten Intel by such a large margin that there is no contest? For now, based on our preliminary testing, that is the case. The launch of AMD's second generation EPYC processors is nothing short of historic, beating the competition by a large margin in almost every metric: performance, performance per watt and performance per dollar.

Analysts in the industry have stated that AMD expects to double their share in the server market by Q2 2020, and there is every reason to believe that AMD will succeed. The AMD EPYC is an extremely attractive server platform with an unbeatable performance per dollar ratio.

Intel's most likely immediate defense will be lowering their prices for a select number of important customers, which won't be made public. The company is also likely to showcase its 56-core Xeon Platinum 9200 series processors, which aren't socketed and only available from a limited number of vendors, and are listed without pricing so there's no firm determination on the value of those processors. Ultimately, if Intel wanted a core-for-core comparison here, we would have expected them to reach out and offer a Xeon 9200 system to test. That didn't happen. But keep an eye out on Intel's messaging in the next few months.

    Looks to me like AMD has done the impossible. More cores, more memory, more PCIe lanes compared to Intel and all that at nearly half the price. And without Intel's abundant security issues.

    For the first time in a long time I'm actually impressed by a new cpu generation.

    AMD 64-core @ $6,450 - $6,950. Or $4,425 for single socket. If these numbers are right.

    The Intel Xeons do not compare well.

    Even if Intel retaliates with price cuts and new chips in mid-2020, AMD is going to cut into that market share this time.
