I have Ryzen 7 1700 from about an hour's worth of testing, I am going to suggest anyone wanting to get maximum performance use the performance governor. The on-demand governor sucks and will not allow the CPU to clock as high as it should.

Thanks for a great, informative review. Seems like Ryzen will provide the development workstation upgrade I'm looking for.
The conclusion point out three benchmarks that are problematic for Ryzen; however, only one of those (Himeno) shows Ryzen losing to the closest 8-core Intel part (5960X). In general the "challenging" benchmarks for Ryzen are ones that seem single-thread heavy and clock-speed dependent, as it's still able to outperform Intel parts costing twice as much. Outside of Himeno none of the results show particularly negative results for Ryzen. Every time it loses to the 7700K, Intel's more expensive 6 and 8 core parts lose to Ryzen, so that seems to match expectations. Similar IPC. More cores for less. Still can't overcome giant clock speed disadvantages. Fair trade off in my book, but wanted to point out you seem to be dinging Ryzen for poor performance against the "cheaper" Intel part and not acknowledging it trouncing the more expensive Intel parts (6800K + 5960X) in the same tests.

This CPU is really amazing for professional applications. I am very interested how it will perform with games.

AMD has confirmed that Ryzen has ECC enabled. Some motherboard manufacturers like ASRock also have ECC capable boards. Is there any chance you could test the ECC capability - perhaps with ecc_enable_override=1? I haven't read of anyone who got ECC actually working yet.

Can you expand on this, please? What is the performance governor and the on-demand governor and how can I switch between these? Obviously they control clock speed but it's not clear if you are referring to BIOS facilities, kernel facilities, or some userland utility. I pre-ordered the same CPU and want to be as prepared as possible.
On most distros you can configure which one is used from userspace using the cpufreq-set program from the command line. Or a graphical utility as well (usually a tray pluging etc..)

Looking in the more detailed specs, most mainboard manufacturers make this clear, so it's highly unlikely that the current desktop Ryzen platform will have ECC support at any point.
We'll likely have to wait for "Pro"-CPUs or boards - or even Opterons.
Edit: It might be different after all, according to AMDs tech marketing people: https://www.reddit.com/r/Amd/comment...other/def6vs2/
I guess we'll have to find out if the boards indeed do support it.Last edited by tg--; 02 March 2017, 06:42 PM.

Thanks for the info cb88. I will try to learn more about the cpufreq kernel drivers.

I expected this sort of review across the board. This is a completely new architecture, and I expect that a lot of performance issues will probably get ironed out over the next 6 months to a year. Anyways I was looking at the review and have two questions about the review.
Question 1: I know that the review is using 16GB of memory for the Ryzen system, but this tells me nothing. What ram kit is being used on the system, and what are the ram settings?
Question 2: I noticed that this review, and other reviews of it's kind do not mention how sensitive the processor is to ram timings. Is there any chance to run some further testing on ram speeds and timings. I created a list of timings that should be easily obtained with a ram kit...- 14-14-14 Cas latency test speeds: DDR4-2133, DDR4-2400, DDR4-2666, DDR4-2800, DDR4-3000, and DDR4-3200.
- 15-15-15 Cas latency test speeds: DDR4-2133, DDR4-2400, DDR4-2666, DDR4-2800, DDR4-3000, and DDR4-3200.
- 16-16-16 Cas latency test speeds: DDR4-2133, DDR4-2400, DDR4-2666, DDR4-2800, DDR4-3000, and DDR4-3200.
- 17-17-17 Cas latency test speeds: DDR4-2133, DDR4-2400, DDR4-2666, DDR4-2800, DDR4-3000, and DDR4-3200.
Note: In I would expect performance differences where the higher the timings, the worst the performance, but The real question is how much performance is really lost.
Question 3: Any Chance to repeat the tests from Question 2 on a DDR4 enabled intel system?
