so i got a laptop cooling pad for my A15 and tried this again and this is what i got -

Asus Tuf A15
Ryzen 4800h

FFS... lol, that's a good chunk faster than my 3600 desktop chip.

Thought i would give some mild overclocking a go, +100Mhz to 4.3Ghz, wont run MT, this is a really early really poor quality silicon chip.

MT remains at about 3800, ST 490, a very slight improvement.

I'll up date later, got to go out...

Objection!

LTMatts Single thread score of 544 should be in position 17 not 15.

Your rules which you applied to my entry of 544 are that if you dont beat a score already posted you go below previous entries not above!

Consistency when applying rules is important, well unless it was a made up on the spot rule that you have since forgotten!

I have to say that I am very disappointed......




That the Beer above is not in my hand!

:D

On a more serious note it seems 544 is currently the limit for single thread with Ryzens.
We have a 3600 - 3900X and 3950X all achieving the same score.

Well unless the XT's can better it.

I did say that didn't i? sorry, i forgot about that...

@humbug Could you update my single core score please? Thought I'd say hi to the Intel boys...

uc

Procedure:
1. Set cpu multi and voltages to stock, pbo disabled, SMT disabled, CPPC enabled and CPPC Preferred cores enabled. Run Cinebench R20 single core with hwinfo open - check CPPC is working as expected and make a note of the voltage your speedy core runs at (1.326v in my case) then reboot to bios.
2. Set your cpu voltage to fixed, do some fooling around in windows to make sure the droop under load hits and holds the same voltage you noted above. In my case this is LLC high with 1.375v manual to give 1.326v sustained under load. Once thats dialled in reboot to bios again...
3. Set cpu ratio to per ccd mode, then set your ccx's at or close to your normal 24/7 overclock. Boot to windows.
4. Run Cinebench R20 single core to do a final confirm that your voltage is correct and make sure you're looking at the right one - SVI2 TFN for CPU core in hwinfo.
5. Open Ryzen master, make sure only multiplier adjustment is included and start upping the multiplier on your best ccx only running cinebench each time. Dont run multi by mistake though ;). I went in .25x increments not expecting to get much but it went up 250mhz over my stable all core oc. You'll get a black screen reboot most likely when you get to the limit, so take your screenshot each time it passes.

Ryzen master screenshot below included for my settings on my highest stable run:

I hope that gets some more Ryzen's up there with the Intel boys, its almost a 30 point gain for me. Obviously you can't run this 24/7 as anything more than single core load will crash it, but then I highly suspect the same goes for the rest of the scores in the top 10. This was done with no cores disabled though, so no hotspot risks and due to SMT being off the core doesn't work nearly as hard so current draw is nowhere near as high. I saw a peak wattage of around 18.5w - sure that's high but with PBO enabled I hit 18.9w on a single core running the same single core R20 test so... Still, no special cooling needed, just make use of core parking and cppc (and Ryzens natural programming to avoid sending more work to a ccx under high single thread load) so that you can run the other cores in your CCX beyond stable limits as no load will ever go there.

Good gains in membench with SMT off too...

Good Grief.... nice, that's spit the Intel CPU's up a bit, if you could get that to 5Ghz you would probably end up second or third.

Updated :)
