9950X, what the reviews don't tell you - because the reviewers don't know

Here’s a hypothetical, you have a buddy who is choosing between getting a 7950X or a 9950X for production workloads, and after listening to the reviews you finally want some objective info to help him (or her) make an informed choice.

Don’t worry, I will get to telling you why I think the reviewers are in dire need of a proctologist, because their heads are so far up their own backsides, that they can see daylight, but first the facts.

I did something that nobody else thought of doing (probably because they don’t know how) and that is a direct comparison when I lower the performance of my 9950X to match the maximum performance of my 7950X in CineBench R23.

The way I do the test is to first run CineBench in a standard configuration with no monitor software running, so that I get a clean result. After that, I do another 10 min run and then screenshot the monitoring software (in my case Ryzen Master) when the CPU has reached its maximum temp and power draw.

Of course, I am running on Windows 10 and not WinTel 11.

As far as cooling is concerned, I use an Arctic Liquid Freezer III 360 with three Phanteks T30 fans, and the paste I use is Thermal Grizzly Kryonaut Extreme. My ambient room temp is around 30 degrees Celsius because I have had two spine operations and have spinal arthritis.

My motherboard is just a bog-standard X670 Gigabyte AORUS Elite AX. I don’t need an expensive X670E to get the best out of my CPU.

First off, here is the maximum result I achieved with my 7950X at the maximum safe voltage for TSMC 5 nm which is 1.2 Volts running CineBench R23 for 10 minutes - FYI this result is after having run my 7950X for about 20 months 24/7 only rebooting for driver updates, hardware upgrades or when the OS plaque, as I like to call it, started making itself noticeable (thanks Micro$haft):

The result is not the highest I can get from my 7950X, the thing is though, I benchmark to configure, I don’t configure to benchmark, so this is running my 24/7 safe clocks and voltages.

Here are the stats for that run after my system had reached homeostasis. My system was running at the maximum safe set voltage of 1.2 Volts - what you see under “CPU Telemetry Voltage” is the get voltage (after the voltage droop for all core workloads):

“Not bad”, you might be thinking. My results are a damned sight better than anything that anyone in the Tech Media/YouTube can achieve on a 10-minute run without resorting to exotic cooling (like chilling or LN2).

Now we get to the closest I could achieve to the same CineBench R23 score I got as a maximum for my 7950X result above after a 10-minute run with my 9950X.

Here are the stats for that run after the system had reached homeostasis. My system was running at a voltage of 0.97 Volts Set (and I have been running it 24/7 like this for a couple of days now, chucking various loads at it without any problems).

To get the same result as my 7950X with a 360 rad AIO cooler, I could use a cheap, but good, $20 air cooler with my 9950X and still come out ahead on temp.

I am getting the same result with my 9950X as I did with my 7950X with 65% less CPU power draw.

To put this into perspective, if Intel came out with a flagship CPU that could achieve the same performance as the previous generation flagship with 65% less power, then reviewers would be masturbating themselves into a coma.

“But what about maximum performance”, I hear you ask.

Let’s first turn to the God-King of overclocking, Der8auer.

He got his 9950X, delidded it, applied liquid metal, and then did direct-die cooling and this was his result; his ambient room temp is also about 5 degrees Celsius lower than mine:

His CineBench R23 score was 44599, his power draw was 289.6 Watts and his temp was 94 degrees Celsius.

So what can a no-name rando lowlife such as myself possibly do to compete with the overclocking maestro?

Thank you for asking gentle reader, and I would answer with this:

And here are the stats:

Of course, I did none of those fancy, delidding, liquid metal, direct die, things like Der8auer. All I did was slap my CPU into the socket and whacked on my cooler, like a pleb, (well that, and of course knowing how to configure Ryzen didn’t hurt).

That being said, compared to Der8auer, my score is over 3.3% higher, my power draw is 28.3% lower, and also my temperature is 13% lower than his.

I did find that the latest beta BIOS I was using (AGESA 1.2.0.0a Patch A) still has some ragged edges. Nothing that affected stability per se, but certainly something that will show increased performance in the future.

Sadly, the reviews of the Tech Media/YouTubers of the 9000 Series of AMD CPUs has continued the devolution to the level of glorified infomercials shown in the past generations of Ryzen CPUs.

Let’s compare and contrast shall we?

These self same, “We only test out of the box performance” liars couldn’t break out XTU fast enough when Intel brought out their 12th Gen Alder Lake CPUs, which needed a new OS, just so that they would function.

Of course, these stalwarts of integrity - for the sake of “Fairness” - shifted their reviews of both Intel and Ryzen CPUs over to WinTel 11 which they knew nerfed the AMD CPUs compared to Intel.

So are these reviewers - and I include all the big names in this - too lazy, too stupid, or just plain too corrupt for Intel marketing dollars, to have learned to properly configure Ryzen almost five years after I wrote my first guide on how to get the most out of AMD CPUs?

They have the Intel blinkers on when it comes to Ryzen and their only bloody efforts to do any kind of configuration consists exclusively of “Moar Powa, Moar Gud”.

To end this, I would turn back to the original question I posed, which was, given what I have shown you, would you advise your buddy to buy a 7950X or a 9950X if he (or she) came to you for advice?

Well, they (reviewers) mostly just follow AMD’s benchmark guideline, not necessary “out of the box” configuration. I don’t think such as “Xbox Game Bar” should be an out-of-the-box configuration.

PS: The major issue of Ryzen 9000 is the price. It is well above the street price of its 7000 counterpart.

While this is true for certain X3D Ryzen CPUs, I did write a comment on the Gamers Nexus video that revealed the 7000 Series X3D lineup.

"Steve, let me make this easy for you and write your review:

For production workloads the 7900X3D and the 7950X3D are a waste of sand, and for gaming they are a waste of money.

The only one worth getting will be the 7800X3D when it is released".

I see no reason to change my mind on this.

Apart from anything else, I am a proud member of the PC Master Race, and don’t want any of that Console Peasant XBOX stuff running on my system. :rofl:

I am really happy that the price for the 7000 Series CPUs has come down, but like I said in my post, I can run my 9950X at the same performance level as my 7950X with a $20 air cooler, and wouldn’t need to pay over $100 more for an AIO.

That kinda evens it out a bit.

Just two days ago, AMD notified us that “Ryzen 9 9900X and 9950X have Windows Game Mode core parking optimizations installed by the AMD PPM Provisioning File Driver,” and that “Windows game mode must be enabled,” “Xbox Game Bar must be enabled and up to date in the Microsoft Store,” “the legacy Control Panel Power Options must be set to the default ‘Balanced’ scheme,” and that “sometimes Windows does not apply the correct provisioning after the CPU installed has changed. You can try uninstalling then re-installing the AMD Chipset Driver as a workaround, but a fresh install of Windows is ideal.” That’s a lot of hoops to jump through for a dual CCD processor. Yes, we tested both 9900X and 9950X with those optimizations enabled. Previously this was required only for the dual CCD X3D models, so that games could be pushed onto the cores with 3DV cache. On Zen 5, AMD is using the same mechanism to improve game thread allocation, probably to put them on the cores with the highest default clocks. The difference should be pretty small though. I doubt it’s more than a few percent and I probably would rather get rid of Game Bar instead.

I don’t, I deleted all that XBOX stuff, and don’t need it.

I know however why AMD wrote that.

It is because at stock the 9950X maxes out the PPT at full load and will downclock cores to stay within that limit as you can see here:

CCD0 clocks to 5.166 GHz and CCD1 only clocks to 4.88 GHz under full load.

Because I know how to configure Ryzen I don’t need to give a damn about Windows Game Mode.

Nobody has said a single bad word about the 9950X’s Cinebench performance. It reliably posts at least 10% over the 7950X across pretty much every test I’ve seen, at somewhat lower power.

And it’s not news that it’s piss easy to outscore PBO with a manual all-core OC. Always has been since Zen+ (did Zen have PBO? I didn’t jump until Zen+). The difficulty with Zen 3 and onward is that a well-tuned PBO/CO setup will very reliably hold an advantageous position until ~60% (at minimum) of the cores are loaded versus even a bleeding-edge manual OC, and in lightly threaded workloads this advantage is larger than the peak multicore gain available from setting a static OC. For a lot of use cases, this means better overall performance with fewer headaches.

I guess you have some evidence for that assertion?

If you do, then please post it.

It’s always so easy and so obvious after someone has shown you how to do it, isn’t it?

Which assertion requires proof? How would you like it proved out?

I love the implication you showed me anything new whatsoever by “hey so here, set your voltage to number too hot to actually run with my cooling setup and I know it, wonder how and speeds to well below what I already know the chip can do, perhaps because I’ve done it before and slowly increment the speeds up until it crashes, then back it back off”.

That’s basically Overclocking 101. 102 might even get into stability testing that isn’t it runs Cinebench so it must be stable, or how you can have a system that’s “stable” in that it doesn’t crash, but exhibits weird behavior like hilariously bad low frames in benchmarks that aren’t particularly famed for being awful about that.

Yeah, we really must stop meeting like this, people are starting to talk. :laughing:

Yeah I have been getting treatment from my doctor for my irony deficiency and I am glad to see that the meds are working :laughing:

If I had a nickel for every time someone has turned around to me and said, “Yeah, well everyone knows this” after I had told them something, then I would be a very rich person.

So please excuse me if I press “X” to doubt on your comment.

Is your chair comfortable enough? Which flavoring do you enjoy?

If we get lucky, the butter line that’s hooked up to chairs will refill shortly.

When set it was #3 worldwide, and it’s still #1 US and #5 CPU score. On a little Freezer 34 Duo that I only recently retired because it didn’t /quite/ keep up with my 5950X.

I have more receipts if you want them.

And I am typing this quickly, because my keyboard is running out of ink. :grinning:

Please stop reading every response as a personal criticism and responding in kind, ignore it or step away if you have to. Nobody is going to take this or your other, identical, thread seriously when every other sentence and post is basically trolling.

You seem like you’re passionate and smart, but that behaviour is just shooting yourself in the foot.

  1. Asserting what reviewers know and dont know is a dangerous game
  2. I dont know what sorts of tests were conducted (or the results they yielded), but spreadsheets are not sexy, so what do I know…

AMD did this because of shameful core to core latencies between two CCD’s. You want to park game on single CCD now and if game use more than 8 cores its sux. Honestly, I don’t know how AMD could screw this up: same I/O die, same Infinity Fabric traces on the CPU PCB, why did 80ns turn into 200+ns?!
