Info 64MB V-Cache on 5XXX Zen3 Average +15% in Games

[Kedas]

Well we know now how they will bridge the long wait to Zen4 on AM5 Q4 2022.
Production start for V-cache is end this year so too early for Zen4 so this is certainly coming to AM4.
+15% Lisa said is "like an entire architectural generation"

...the Beta Bios I was running for a similar MSI board already kicked the CPU in pants when I mistakenly enabled the CPU boost option in the firmware, but this was not stable.

Which BIOS you using for your Tomahawk? I am still on 1.2.0.6c for the B550 Tomahawk since I keep fTPM disabled and found a reliable way for the X3D single core boost to work. I just checked the X570 Tomahawk page and we have same BIOS releases unsurprisingly.

Looks like Tomahawk owners are kinda left in the dust when it comes to newer beta BIOS' from MSI, but it isn't a big deal unless a real 5800X3D unlock arrives (doubtful).

If the board has the game mode option in the UEFI you should try it. Tomahawk B450 set my 5600G to 4.7GHZ all core, but all power saving features were still active. Max voltage was lower than OOB PBO.

I've been googling it and people said it was bad, with voltages still too high. I doubt enabling it on the X3D will do anything but increase voltages, but I am curious.

Enabling PBO in BIOS with scalar of 2x does increase core clocks by a little bit, effectively overclocking the X3D by a miniscule amount. With my BCLK OC, enabling PBO scalar 2x creates boot instability which I find kinda interesting. Maybe I need a bit more voltage, which I can increase with MSI's tools.

We can even turn on Game Boost with Dragon Center. Not brave enough to enable it right now.

My mistake. I derped on the 5800X in his sig.

Oh I assumed you meant 5800X cause game mode should definitely overclock it! I am willing to be a guinea pig for the X3D game mode soon though, haha.

For science.

As someone who had to send back my x3d, I am glad that mine boosts well, runs memory at 3600 flawlessly, and stays well below 80c. (gaming 60c, benching 75c)

So, embarrassingly, I was using the stock bios still. I had done several builds lately - including a 5800X3D on a x570s MSI board and somehow I thought I had already updated it. Nope. So, on the earlier (earliest listed on the downloads page) bios releases it just ran at 3.4 ghz, no boost, etc.

I had been so pleased with the temps and lack of noise from my PC Turns out that was all a mistake on my part.

Ok, so got that firmware updated to the 7/17/22 drop but boost was just not happening. Actually, it was worse. Taking forever to spin up during benchmarks, Novabench being my go to for a 2 minute sanity check bench. Dropped 20% performance from my B450 board. WHAT IS HAPPENING???

Check the power plan, somehow it is at power saving? What the crap? Change that. Bother to activate windows. Enable Above 4G decoding, etc.

So now I am at the latest (non-beta now! woo!) bios with official X3D support. Performance is up across the board and I am *done* tuning my main rig for the foreseeable future.

With a Frost Commander (enormous) cooler, I am only getting boost to ~4.4 ghz or so, but temps are OK. It's fine, I am not going to fight it at this point. It does run memory at 3600 with zero issue and generally after getting it to run like it's supposed to and seeing solid gains over my previous B450 setup I am going to wait a bit now.

FWIW, enabling the Game Mode on a different MSI board (x570S Edge Max Wifi running the beta bios for x3d released in May) and X3D CPU by mistake (I must have clicked it, but in "basic" UEFI mode all it does is glow a little if it is on?) and it ran the CPU at ~4.7 ghz all core but it wasn't stable and temps were leading me to believe there was way too much juice. @Schmide having lost one, I immediately powered off and checked that setting - confirmed it was on - and turned it off.

I am guilty of spending way more time tweaking builds I am selling and then with my own PC I just put it together and expect it to work. I am not sure why that is ¯\_(ツ)_/¯

If you screw up someone else's build then at least you aren't stuck with it, maybe? Though one would hope you'd fix problems/replace smoked components before selling the units to customers.

You take my meaning wrong.

I don’t mess or experiment with builds I sell, I test and tune them. Updating firmware, disabling stupid performance settings, setting power limits relative to the cooling capacity of the whole system, setting fan curves, ensuring performance is good with benchmarks, overnight stress testing, etc.

I get a lot of positive feedback for building quiet and stable computers and I’d like to keep that way.

And then for me I stuff it in a case in the minimum time and call it good. Twice I can recall spending the same time as I spent on client PCs for myself and those were long held builds.

 

[DrMrLordX]

I test and tune them.

This is the part I was getting at. Tuning doesn't always work out, especially if you are overclocking.

 

[blckgrffn]

I am not, especially by Intels definition.

If anything, I tune them to run more within the specifications and not the other way around.

For the folks I build for, they are either happy to pay for the parts that are supposed to run faster or are going to be completely oblivious to single percentage performance gains relative to “stock” performance. Modern overclocking is not anything like it was when you could get massive gains by flipping a FSB or get an extra all core ghz by changing a multiplier and never even adjusting the voltage. It’s not worth my time, but understand why some bother anyway.

I am seeing single core boost happen more often using the AMD Ryzen™ Balanced LowPower plan on overclock.net:

CPUDoc now features a custom dynamic power plan with ultra low power in standby: https://github.com/mann1x/CPUDoc/releases/latest These are the custom power plans I've made for my 5950x. I have tested them as well on a 3800X and 5600G (not very thoroughly). They should not interfere with PBO...

I highly recommend downloading PBO2 Tuner and configuring -30mv per core and limiting PPT/TDC/EDC with Task Scheduler so the settings apply on Windows login:

Scroll Down For Gaming Results If Not Interested In Details TLDR: 5800X3D is a monster at gaming, is easily OCd, and runs hot and beats even a tuned 5950x in most games; for general computing the 5800x, and more importantly now, the 5700x trounce it when OCd as well but cannot match it in...

This provided a big drop in voltage, temps and near zero performance loss.

I'm on a 1080p 60Hz monitor and have a Ryzen 5800X.

with a 60Hz display any fps improvements would be engine related for whichever games you play

Imagine Zen 4 with Vcache that has an all core boost ~5.3Ghz in games. It should easily score above 150 on that scale. I don't see how Raptor Lake can be faster in games, unless it somehow brings 40% higher fps than Alder Lake...

ZEN4D vs RPL looks like murder more than anything else.
Curious to see how it will really be.

Four years brings us to 100fps on average for all major desktop cpu models and a 3090ti at 1080p. Although at least it is with RTX on and "very high" graphics settings for that game. Better than a PS4 or 5 I guess. More proof that for gaming anything more than a $200 cpu is pointless except for some edge cases.

Eh, something to think about, Spider-Man is keeping the 8 e-cores busy while the game is running by using them to compile shaders in real time. RPL will have twice as many e-cores at several levels while running them faster. It'll be interesting to see how that helps. On console, it uses precompiled shaders.

Several PC games precompile shaders. All the Call of Duty PC ports do this.

 

[LightningZ71]

Yes, but, in particular, the port of Spider-Man does not use precompiled shaders on PC. Over in the Alder Lake thread, someone posted a snippet from one of the Devs pointing this out.

 

[Joe NYC]

Interesting pricing info from my local Micro Center. Price of 5800x3d > 5900x. Quite unexpected.

 

[Ranulf]

Eh, its been that way for months. 5900X has been at $400 since maybe April? The big price drops were in June/July with sales down to $330 on Prime Day and a few other places in $320-40.

 

[Markfw]

Yup, supply and demand. The 5800X3D in many cases (especially gaming) is superior to the 5900x. If they want more cores, they go for the 5950x.

 

[LightningZ71]

While the 5800x3d may be better for gaming, I can't help but think that the 5900x will have greater longevity due to the extra cores. I conceed that the Broadwell high cache processors stayed relevant for a very long time, but, the comparable quad cores had substantially less cache than what the 5900x has.

 

[DrMrLordX]

5900X is about to be replaced by the 7900X, so gotta clear supply out of the channels quick!

 

[UsandThem]

When / if I see the 5900X below $300, I'm in for one.
