Yes give it a go let us know what happens. :cool:

True, but in fairness they did do the more relevant test already against the previous gaming king (45 game comparison against the 7800X3D).

They could have just as easily made a video of the 9800x3d getting absolutely destroyed by the 285k in everything but gaming. I just feel the 285k competitor is the 9950x not the 9800x3d it's not even Intel's fastest gaming chip.

after updating to latest MSI BIOS (AGESA 1.2.0.2b), I've got something that this might be, I'll toggle it and see if multi threading is disabled

Yep, SMT disabled:

Are you then locked into that until you go back to BIOS and disable the option again or can you toggle it in Windows somehow? I thought we already had an option to disable SMT in BIOS. :confused:

9950x3d Vs 285k that will be best from both , problem is AMD have all bases covered

Yes that is a big problem for Intel. :cry:

Yeah there's been an option to disable SMT in BIOS for all amd64 architecture platforms for as long as I can remember. I don't see any way to toggle this in any of the provided MSI Center tools, nor would I expect to since it's always been a BIOS toggle in the past.

Not sure I see the point of this really, anything you can suggest I can do some cursory testing with to see if it makes even a small difference?

I mean maybe Counterstrike :cry:

. I guess some people will use it for maximum benchmark scores but I don't see it being useful for normal usage. It really seems quite a useless option, and quite a dangerous one because people will enable it with X3d chips thinking they are getting performance increases. At best it might be marginal few percent in some games but huge losses in everything else. No one really recommended disabling SMT on AMD before.

Did you ever try CPUDoc it allows control within windows and seems better solution. https://github.com/mann1x/CPUDoc (Edit- not sure if that was ever updated for Zen 5 though.)

looks sort of like a more convenient "process lasso" with more features I guess, not tried it and tbh don't fancy installing all of visual studio and all the deps to build this

I do wonder though, have all the scheduler and windows improvements with core parking made fiddling with process lasso and this tool mostly redundant?

Yes, but up until this release the top end K SKU of the latest generation was also the best gaming chip! I agree it wasn't worth making a video of, but some will find it useful/love rubbing salt into Intel's wounds!

Seems a decent jump up from my 7800X3D (although not sure how well Time Spy relates to everyday gaming use?)
Same settings for both (-25 all core)..

Hmm my 9800X3D seems hot at stock, idles at 60 then very quickly boosts into the 80s.

Does that sound a little toasty? Running a Noctua DH15 Gen 2 (admittedly at low RPM in the 400s).

Going to repaste the CPU… I did admittedly have a bit of a fail when seating it (initially didn’t remove plastic cover… derp) which took off a little paste but I’d be surprised if that did much.

I suppose doing the curve optimiser offset will help.

Mine idles at 43 and the hottest it’s got is 71 (playing FC6), H150 Elite AIO, -25 all core and using MX6 paste.

Yeah I've found mine gets super toasty under full load, and gets there pretty quickly.
This is with a 420mm AIO.

Not that I expect this will change the view of some, but they make the differentiation between a CPU review and an upgrade guide. The former informs the latter of course, but the point is clear.

Stock: 35-38c here at Idle, after a few hours gaming drops to 40c, 50-62c gaming (CoD, so not very hard on CPU), 80-85c with OCCT CPU stress
OC: -40 All core curve, +200 boost, 85-91c with OCCT CPU stress

Arctic iii 280, replaced stock fans with 4x P14 Max in push/pull, Thermalright TF8 paste.

Cenuij · Sunday at 11:13

Few rounds of Nuketown in CoD with -40 all core, + 200 boost, but CoD BO6 doesn't really push the CPU at all tbh

I can't go higher on the CPU without ECLK right?

Sideeffect · Sunday at 11:29

No I don't think so.

Did you see this awesome guide?

Cenuij · Sunday at 11:29

151w, 89c - decent draw in the silicon lottery?

I did, right after I slapped -40, +200 straight in and pulled the trigger on a cpu stress hehe
