You will do elaborate power efficiency tests of Ryzen won't you

TechReport was the only site with fancy power efficiency tests, performance per watt etc. Lately you don't do such tests anymore :( Hopefully you're going to perform them on Ryzen?

Yup I'm hoping the same....
Main machine: Core I7 -2600K @ 4.0Ghz / 16 gig ram / Radeon RX 580 8gb / 500gb toshiba ssd / 5tb hd
Old machine: Core 2 quad Q6600 @ 3ghz / 8 gig ram / Radeon 7870 / 240 gb PNY ssd / 1tb HD

I think everyone wants the full suite for this one.

This. I always found the task energy test quite interesting.

Would be really great. Actually I am looking forward to it now!

I like Hexus' measurements the most. No one reports lower figures than they do. I'm just not sure what kind of watts they use - their 6600K system consumes 23 W on idle while mine consumes 40 W. The components are comparable, the main difference is Windows version (3 less here).

I'm likely the only person who's interested in this, but I'd love to see how Ryzen performs when trying to run virtualization, like KVM, Xen, VMware, etc... IF Ryzen ends up being a good CPU (the 8c/16t setup is important for the workloads I do), and doesn't flip out when trying to run Workstation Pro, or KVM/Qemu in Linux, I can see myself splurging a little for a 1TB Samsung 960 Pro, and dual-booting between Win10 and Linux.

I'm also hoping that Naples ends up being both performance and price competitive with Intel's Xeon lineup. I've been looking at a lot of servers (dual and quad socket servers, mainly), since I really need a lot of threads, but dropping at least $4K per-CPU isn't really something I'm looking forward to... If the Linux ecosystem were more mature for OpenPower (and the prices not crazy), even a single socket Power8 (8c/64t) would be perfect.

Getting a proper accounting of the actual performance and task energy for a processor is absolutely vital to getting a real accounting of how efficient the chip is.

Case in point is that many sites use Prime95 to measure power consumption and then just stop there and assume that power consumption == chip efficiency, which is flat wrong.
They fail to factor in that Prime95, if run correctly, is also a benchmark that can produce performance data to quantify how much work is actually being done while burning a given amount of power. Without that information, the power consumption number in isolation is pretty meaningless.
4770K @ 4.7 GHz; 32GB DDR3-2133; Officially RX-560... that's right AMD you shills!; 512GB 840 Pro (2x); Fractal Define XL-R2; NZXT Kraken-X60
--Many thanks to the TR Forum for advice in getting it built.

http://www.tomshardware.com/reviews/amd ... 987-8.html

So power consumption seems to be really good even accounting for performance. The results are suprising. Am I reading these results wrong? 1800x has Less power consumption than a 7700k? And why is gaming performance much better at 1080p than previous reviews? Ultra settings making gpu limiting factor? Also why does ryzen put in the best frame times when gpu becomes the limiting factor? What changes?

This is why I need techreport. Need power consumption results and more in depth framd time analysis.
