Someone's Ryzen 1700 study, interesting.
Click!

Alright, so I've spent the past few days trying to plot out the frequency/voltage/power consumption curve for my R7 1700. Basically what I did was set the speeds to 100 MHz intervals, and then adjusted the voltage until I managed to get it Prime stable for at least 2 hours*. Once I got the stable settings locked in, I ran at each speed for 2 minutes and recorded the actual voltage and CPU package power reported by HWInfo (average over the two minute period). I also got the total system power consumption by using a Kill-A-Watt and taking the number that was displayed most often (the total power fluctuated slightly, but this should be accurate within a few watts).

*3950 MHz may not be completely stable. Based on the power/heat being produced I didn't want to run P95 for many hours at this setting when it was obvious that I wasn't going to run at this speed.

Results:






Conclusions

  • At least with this chip, going to 3.5 GHz on all cores is "free" from an energy efficiency standpoint. After that point the amount of power required for each additional 100 MHz starts to ramp up.
  • I'd say 3.7 GHz is basically a "no brainer". There's a slight loss of efficiency compared to stock, but it's pretty small. The chip still runs cool and this preserves your single threaded boost level.
  • 3.8 GHz is borderline: energy efficiency is worse and overall power consumption is higher, but they're still not unreasonable. Whether it's worth it depends on whether you favor efficiency or performance.
  • At 3.9 GHz you see a pretty large jump in power consumption and heat produced. It takes 40 watts more and pretty high voltage for a rather marginal increase in frequency.
  • After 3.9 GHz the chip starts to "go critical" and it's not even remotely worth it to push further.


Obviously there will be difference in other chips, with some running faster or slower at a given voltage, but assuming this general voltage curve is accurate for the architecture, I feel like going beyond about 1.3 volts isn't worth it unless you don't care about power consumption at all. The increase in performance you get is too small compared to the extra power and heat required.

I hope some of you may find this of interest. I ordered a couple of 1800X when B&H Photo had them on sale, so I may try to plot the voltage scaling for them next to see how they stack up.

A fair summary of Ryzen present state of affairs, very new, lots of tweaking and undergoing gradual maturing... like his essential hwinfo64 utility.
Click

I have just released HWiNFO v5.47-3115 Beta and pulled the earlier builds.
Another note about the new CPU current/power measurement for C6H and PRIME X370 under ASUS EC sensor. It seems that neither this value is accurate, as it covers the Vcore rail of the CPU only (VDDCR_SoC is not measured/included). Moreover due to the nature of implementation (HW/firmware), under frequent Vcore fluctuations the final power value might not be accurate.
I will try to find with ASUS a better way how to measure CPU power using on-board circuits, but don't know if that will be realized..
So don't expect to just throw down the money, grab the hardware, jump in and start overclocking to the max.

After binning some dozen X1700X i have to share that about 15% of cpu's did not do 3200 divider and 10% would get stuck at 55 over 110 bclk,each cpu was tested after clear cmos with saved profile,same componentes,everything same.Also,most of x1700x did 4000-4050 cinebench,good pieces 4070-4100,best is 4150@ 1.42 llc2 R15 on ambient water.

also , Malay or China it did not make a difference in oc ability.

DIY 3D Print Corsair AM4 bracket?
Spent half an hour and drew a Corsair AM4 bracket.

I haven't printed or tested it yet, but it should be a perfect fit.

It's made a lot thicker than metal brackets to overcome plastics's lower strength. It should match the strength of 1mm steel brackets.

File can be opened in solidworks 2014 and up once you remove the txt extension.

Loads of raw power to spare.



hwbot x265 Bench
Done at 1080p. Good time to note the low fan speeds and load temps too, totally silent running for now till the gaming card arrives, I guess. lol




HEVC Decoding Bench
Very impressive to say the least...




...
hi mac, i tried these 2 benches on 6700k but results quite similar abt 38fps & 1000+ pts
any idea what factors matter for these 2 tests?

will read, thx
wat i meant was, i saw some x264 fps results for ryzen - fps is wayyy beyond wat 6700k could ever reach, when the task is highly parallel/threaded
so i tot it would be the same for x265 if task was similar, but i was surprised the results are close to 6700k oc'd...

If you are comparing Ryzen@stock vs 6700k oc'd... maybe see Ryzen vs 6700K stock 1st. The difference isn't that much even at 6700K stock.
http://www.anandtech.com/show/11170/...0x-and-1700/20

Think results also depend on how the tests are set up and if it uses the CPU or the iGPU cos Ryzen lacks any iGPU vs 6700K. If the test is optimised to use purely all CPU cores/threads, Ryzen should likely be favoured.

Do you have the full detailed setup for the x264 test you mentioned?

oh, it's ocn's x264 Stability Test v2.06 - u can also get it from here or here inside the "stress testing" section

it should be purely all cpu cores/threads, no gpu
skylake/kaby i think at most abt 5.2fps (at 5.2ghz oc), so it can't reach the 5.8 fps for ryzen 1700 i saw in this post

Ah, never tried that particular bench before so maybe got to wait for others to comment too.

Nope it's already out 3 days ago end march....now you can save user profile and the cpu core voltage is limited to 1.55 max.

Was referring to the mobo, not the BIOS actually.

You meant the boards lol I assume it's the bios since the boards was actually out the same time as my killer sli. The only problem is availability which is poor for all the ryzen boards compared to the cpu.
