[bug]

Regarding the core parking Bug you can use CPMinCores from Microsoft to prevent that problem until there is an official fix.

CPMinCores

CPMinCores specifies the minimum percentage of logical processors (in terms of all logical processors that are enabled on the system within each NUMA node) that can be placed in the un-parked state at any given time.

learn.microsoft.com

Toms Hardware used that Tool as well because they had trouble even after a fresh install. My bet is a Board/agesa based bug in combination with the driver.

That would make more sense than the driver alone screwing things up like that.

As workaround for an end user that might work, but publishing a review based on such data? I don't know. Several reviewers that I talked to could fix the problem by a reinstall

Frametime Chart

Ah .. we had frametime charts .. people didn't understand them and wanted simpler answers, which I've now provided with the 2023 test suite update

FFXIV Endwalker, my all time favorite game.

Is the integrated benchmark even a representation of the actual game?

That would make more sense than the driver alone screwing things up like that.

Adjusting that setting works, I've tried it, but it no longer runs at default settings, especially power will be affected

 

[msoltyspl]

OF course .. I removed it with pnputil after running the AMD uninstaller, which doesn't remove the INFs

Hmmm, that's really peculiar then (if it was gone from device manager, not reported via sc.exe as started and so on).

I'm just guesstimating as I don't have 7950x3d so can't really check firsthand, but:

- did you try maybe powercfg.exe /listprofiles if there wasn't something weird left / changed / added by that driver ?
- any suspicious scheme overlays ? (powercfg /aliasesh should list those, among everything else), though scheme overlays should be N/A in this case
- was high performance profile also bugged (core parking should be off there) ? (bitsum's parkcontrol should show that in a readable human friendly fashion)
- if the driver was gone and power settings were a mess, transplanting the whole Control/Power registry subtree with via reg / regedit should(?) have fixed it as well. But yea, I can see why wasting time with tinkering wasn't exactly a priority for a day-1 review =)

Good review btw, now I have big dilemma whether to go for 7950x3d or 7800x3d. Probably the latter as my current gpu completely obsoleted the need for streaming relying on cpu - and that was the primary excuse for my slowly aging 3900x. Unless I change this gpu to amd card in the future ...

That's exactly what I did (among other things). Couldn't find any changes, transplating didn't make any difference

Btw I really liked the power profile features of QuickCPU

 

[TheinsanegamerN]

Funny thing he is using medium settings no RT which is very light on the CPU. I don't dare to imagine frametimes at ultra +RT on the 3d. 8 cores are not enough for todays heaviest of games sadly

It's not a matter of 8 cores, its a matter of the game being poorly programmed and poorly optimized. CP2077 on ultra is just an absolute chore to run properly.

Nah, not really. Runs super well on CPUs with lots of cores.. It even takes advantage of ecores.

Honestly, it's just for fun that I like to see GamersNexus test it, I don't actually want anyone to go out of their way to test it regardless. I mean, my 5600 non-x + 6800 XT gives me at 1440p 165 fps, 165hz Ultra maxed out with no drops in frames...

So I mean... yeah lol

I know not many people review Starcraft 2 anymore, but that game LOVES x3d cache. My ryzen 5600 will drop 70 frames or more when big battles break out... but reviews show x3d cache handling it like a champ and then some.


Anyways, great review!

Good to know. I was (and still am) trying to understand the issue.

 

[cowcatwithahat]

Great review, thank you!

 

[BoboOOZ]

Yeah, between CPUs, mobos and video cards I have only upgraded like a dozen times. Using both Linux and Windows and never performing a clean install (except when I switched Linux distro).
But you go ahead and count that as "one example" if that gives you a warm feeling.

Believe me, it doesn't warm me up at all, I need to reinstall windows 11 just for swapping 3600 cl16 DDR 4 with cheaper 3200 cl16 the other day. The machine boots fine, but effing win 11 won't start with the XMP profile enabled.

Some overclocking:

At the beginning of the article, I said it’s ironic that the Ryzen 7 7800X3D is the most tunable of all 7000X3D CPUs. I stand by that observation, given how locked down the 5800X3D was. But this is a good kind of irony, and I must give credit and thank the folks at AMD who decided to loosen the overclocking restrictions for the Ryzen 7000X3D processors.

Overclocking the 7800X3D was one of the most enjoyable Ryzen 7000 tuning experiences. There are plenty of overclocking strategies to choose from, and it definitely feels like the deeper down the rabbit hole you go, the more extra frequency you can find.

But I must emphasize that voltage is the most significant danger for 7800X3D overclocking. I do not recommend using a manual voltage of over 1.15V because any load will push the CPU to TjMax or beyond.

How about ParkControl?

Super weird then. Even the driver's uninstall section in its readme.txt just says to remove it via device manager from the System subtree and that it should suffice.

 

[Xuper]

Well, I guess what he means is a Frametime Chart to display frametime consistency and expose frametime spikes. 0.1% or 0.01% lows are just "average lows" and do not expose micro stutter.

GamersNexus included it in his review and f.e. the frametimes in Cyberpunk 2077 are way smoother on the Intel 13700K than on the 7800X3D. Not really a noticable difference "in game" (if spikes aren't too crazy), but a measurable.

someone explains CP does have issue with this SMT.

But that rarely works 100% as intended, the reality is the more software you install & the more changes you make to the hardware you'll have major/minor issues with drivers/registry settings & even windows updates. I used to install windows "beta" versions for fun stretching anywhere between once a week to maybe at least once every six months from the days of win7 & the one thing I can say for certain is that just like no two (hardware) systems can ever be identical ~ the same goes for Windows or OS in general, even on the same exact machine they can behave differently.

The recent versions also support overlays.

And for 7900/7950x3d users process lasso (formally not free though) is godsent.

 

[FeelinFroggy]

I think the 4k numbers are good. I'm starting to think that I might see a difference if I move out of my 8700k.

 

[Bensam123]

I don't understand why the OS reinstall issue is being talked about so much. If I understand correctly, it really only affects people who are moving from the 7950/7900X3D to the 7800X3D which are a pretty small subset of people because they already knew what the 7800X3D would perform like and the cost as well but went with the higher X3D parts anyway.

Because it's a weird niche issue they HAPPENED to find, and that means there might be others out there. Furthermore, it seems to be adjusting parts of the OS that can't be fixed without a completely clean install - something that should never happen. It makes you wonder what other sort of bugs in their duct tape Thread Director are still there. For instance I have the below happen to me.

I have a 7950X3D and I'm having problems with all 8 of my cache cores being utilized in OW2. My 13900k prior would utilize all 8p cores in W11 and my 5900X would utilize 8 of the assigned cores in W10, however it refuses to use that 8th core. It's the slowest of the 8 cache cores and I assume this is a CPPC problem, but there is no way of shutting off CPPC to verify this, at least on my motherboard, they removed the option to disable it.

For me however none of the cores are parked as I have core parking off, but it refuses to use 1 of my 8 cores for OW2. 13900K had utilization spread across all 8, my 5900X also did.

 

[Taisho]

It comes down to your budget. I see 150 € for 32 GB CL30 and 75 € for 32 GB CL36, so twice the price, but on the other hand only the price of one AAA game

I wonder where these prices come from. In Germany, 2x16GB 6000 MT/s costs: CL36 - 116€, CL32 - 128€ , CL30 - 135€. Source: geizhals.eu. Similarly, though slightly more expensive in Poland. There is no reason to go CL30 with Intel, unless someone simply likes the idea of RAM OC as me, but for AM5 this 20€ doesn't look like much, seeing the performance differences that Hardware Unboxed reported.

 

[mb194dc]

I don't buy that a normal use case for 4090 and 7800x3d is anything less than using 4k or higher screen. System cost is at least 3k?

If you're using anything less than 4090 the difference in FPS is going to be smaller.

This is an extreme niche product. If you have unlimited budget. Most would be better off with 5800xd and spending on a better graphics card and screen?

 

[Xuper]

So which one did you do to solve Core packing fail ?

1) Reset windows

2) Format SSD/NVME then Install windows ?

I generally say, any modern CPU is good enough for 99% of use cases in terms of gaming. Benchmarks and comparisons look jaw-dropping, but all the differences we see are way above monitor refresh rates.

the X670E CARBON has it

 

[wheresmycar]

Out of stock.. and others showing "pre-orders". I'm glad i'm not on the to-buy agenda or i'd be pulling me hair out... actually not, got used to all the hype and then to hit a dead-end for 1st 10-min stock clearance.

I am wandering though, how many units do UK retailers get? Is there a fixed quota or does it vary across the board.

I actually checked geizhals too, maybe I failed looking up the prices

I formatted and installed a fresh Windows .. I'm too old to even try those fancy new "reset" methods and waste more time if they don't work properly t.t
