It's funny to me how much range there is in these tests. Some of these are seemingly backwards with better CPUs ranking so much worse and some look completely random. But wow, the performance on these new TR chips is just insane. Never would've guessed that AMD would be this competitive a few years ago, especially not on the CPU front. Looking forward to the upcoming 7nm launch, can't wait to see what's in store.
- iClaudiusX 8y agoIndeed, as noted in the conclusion there is very little middle ground as performance with this particular NUMA structure is bimodal depending on memory access patterns and power consumption of all the supporting hardware. I suppose it makes the most sense to frame this as an iteration of the original Threadripper with all the design compromises that entails to provide backward compatibility with existing motherboards. I'm definitely more excited for the next generation HEDT chips that hopefully have a more balanced layout like Epyc. AMD have certainly come out of the Bulldozer era swinging, and we all benefit from their aggressive pricing.
- bluescarni 8y agoThe test results on Phoronix paint a rather different picture (i.e., the 2990WX being consistently and markedly faster than any other tested processor). My initial gut feeling reading the results on Anandtech is that Window's scheduler may not be able yet to exploit the processor's architecture effectively.
- fooker 8y agoYeah, I remember AMD's bulldozer architecture coming out much worse on Windows based benchmarks.
- Tuna-Fish 8y ago2990WX has a very complex NUMA architecture that costs it a lot of performance if the scheduler doesn't get things right. Linux has been running on and has been heavily optimized for even more complex NUMA systems.
- 131012 8y agoI'm eager to see the AIDA64-fpu or any other scientific calculation benchmark on linux, as it is the area where the i9 seems to dominate the TR. Sadly, the few benchmarks I've found were on win10.
- nv-vn 8y agoWow, I didn't even realize how big an impact it makes. It literally outperforms everything else on a large margin except for one test, and gets like 117% more performance in ebizzy than the 7980xe.
