I think the IPC gap will become an interesting battle in the near future, especially as gains that came from aggressive speculation have proven to introduce security holes (take your pick of Meltdown, Spectre variant n,...).
- tpetry 8y agoAre there any good post-Meltdown benchmarks conparing Intel and AMD?
- std_throwaway 8y agoAnandtech did a benchmark but that had a flaw in the way they measured the time. Many other benchmarks are with unpatched OS versions to keep comparability. It's not easy to judge when they don't explicitly investigate that effect.
- zelos 8y agoAnandtech updated the benchmarks eventually: the massive performance drop that they attributed to meltdown/spectre patches vanished. https://www.anandtech.com/show/12625/amd-second-generation-ryzen-7-2700x-2700-ryzen-5-2600x-2600/13 https://www.anandtech.com/show/12625/amd-second-generation-r...
- kuzko_topia 8y agoPhoronix is my go to for those in depth benchmarks with security patches
- std_throwaway 8y agoTrue, they compared a lot - but exclusively under Linux.
- protomyth 8y agoThey have added various BSDs to their benchmarking.
- baldfat 8y agoWhich is the main OS that will us CPUs when you count servers. Granted that isn't the consumer CPUs we care about but the work on servers actually trickles down. It isn't some minor group and AMD and Intel are very much concerned about how their CPUs run under Linux.
- kuzko_topia 8y agoTo be fair it's only recently that released the windows version of the openbanchmarking software, so this linux only side of things will change for sure. But yes
- mozumder 8y agoJust use Geekbench. It's great for core performance comparisons, based on actual micro-workloads. BTW We're looking at ~4200 for Ryzen, ~4800 Ryzen 2, and ~5800 for i7 Coffee Lake.
