AMD Says Ryzen 9000 Series Won't Beat 7000X3D Series at Gaming

[A Computer Guy]

1. The new top dog will be a power hog, too.
2. The new 65-Watt CPU won't outperform your last-gen top dog.

Darn, this foils my upgrade plan. Guess I'll have to stick to my power efficient 5950x for awhile longer.

Well, a 65-watt 8-core / 16-thread Ryzen 7 9700X or a undervolted 12-core / 24-thread Ryzen 9 9900X won't be bad choices, especially that AM5 is now a settled platform, so the bugs are less, maybe it's good to try it...

Sure. But they're pointless if you're already on Zen 4.

I saw something on reddit (yea I know ) awhile ago that someone adjusted the power of their 7950x to 5950x levels without too much loss in performance.
(edit) I found the link https://community.amd.com/t5/pc-bui...erence-between-the-7950x-and-5950x/m-p/563342

Because AI is the dotcom boom of the 2020s, and everyone wants a piece of the pie. So they have to put useless NPUs everywhere because it gives investors a hard-on.

I wish someone would find it a good use beyond running chatbots 150% faster, right now there's no point in it being universal. Maybe in five years when it will be in every CPU, someone will write a botnet that leverages millions of home users NPUs to run Skynet. Kyle Reese was supposed to be sent back in time from 2029 in the original Terminator, so we still have five years for that to happen.

NPUs are actually ubiquitous just not in PC. They are in Apple silicon, and high-end mobile devices from Samsung and Google and Qualcomm. That's the reason for the push, to not have the PC be wildly inefficient or grossly expensive to handle the same kind of tasks.

Of course, the best is to wait the 16-core CCD with Zen 6...

Oh no, not the gaming performance. All the hordes of 4090 owners are in shambles.

There's atleast a dozen of us!

Zen 4 reacts very well (that is: not a lot) to lack of proper cooling (thermal limit) or a modified PPT.

The 7800X3D is selling as low as $320 @ microcenter before 10% membership discount. AMD'S marketing team bigger number better!

AMD had a pretty nice die size economy by not having full AVX512 units in Zen 4, though one can argue it was also previously the case.

The actual CPU die size itself is pretty small these days and the FPU is a minority of that die size. Here is Zen4 for comparison:

https://www.techpowerup.com/img/WuHAyr6QC7Ch2JCm.jpg

Going to full AVX512 isn't a big deal from a die size perspective. The bigger issue will be feeding that FPU because its going to be incredibly bandwidth intensive to do so at 5Ghz+ and maintaining full clock speed without heat throttling. It can easily gobble up most of the bandwidth available and starve the rest of the core if they also didn't greatly pump up L1 and L2 cache bandwidth.

I think they've said it'll have up to double the L1, L2, and decoder bandwidth vs Zen4 so it appears they've addressed that issue too.

Wasn't there a plan to eventually bring the X3D cache to all Zen CPUs?

No.

Its way waaaaaay to expensive and AMD isn't able to buy enough wafers from TSMC to pull it off.

What they're doing is releasing their new cores first and then doing X3D updates later when they've got available dies and as a sort've product line refresh. There were big lag times between the new core intro and the X3D variants for Zen3 and 4 but for Zen5 they're rumored to be doing things faster and might have X3D versions out before the end of the year.

Why all this pessimism? Did you guys seriously think the 9000-series was aimed at 7000-series owners?

When are we all gonna grow out of the late '90s attitude of expecting huge leaps of performance and functionality from single generational upgrades?

I second that... for most of us, or gamers, buying into 7000 it would be more interesting to see whats on offer at the end of the AM5 support cycle.

'Buy our 7800X3Ds and don't wait for the next best thing', is what they're saying.

7950X is not better than 5800X3D in game。
9950X will meet same problem

 

[Jism]

I was being facetious.

The 2950X is a 16 core Threadripper, which will be absolutely decimated by a 16 core 9950X.

Exactly. It's based on pinnacle ridge which is 2700X and so. The 5800X alone is 50% faster in pretty much everything. The 9x00 series will provide a rough 60 to 70% even compared to pinnacle ridge.

How is it a problem? The x800X3D and x950X CPUs are made for entirely different use cases.

 

[fevgatos]

I'd still pick a 9700x over the 7800x 3d without a moments hesitation, the same way I'd pick a 7700x over a 5800x 3d. Overall faster products.

 

[Knight47]

Amd is killing it with the new cpu's. 5800XT beating 13600k/14600k and 9700X beating 13900k/14900k.

Is that a serious post or...?

 

[Knight47]

5800XT is up to 12% faster compared to 13600kf.

So yeah, Amd is seriously killing it.

 

[fevgatos]

Ohkay

Are the results on this slide also tested with a RX6600?

Yes

 

[AleXXX666]

How much faster is a 7800X3D compared to a 7700X? 20%? 25%?
How much faster is the 9700X compared to a 7700X? 16%?
There you have it. A 7800X3D is faster in gaming compared to a 9700X....

We won't know for sure until TPU has one in their hands and tested it.

I'm OK with "non-3D" CPUs. Runs cooler, price is balanced. It's the same AMD "know-how" like HBM GPUS VEGA, remember that BS?

Sarcasm aside Ryzen is the worst value at launch. Would someone pay almost 25% more for similar performance when gaming at 720p?
Hey if you want production cpu Newegg has the 7950X for $420 now. Who would pay $399 for a 9700x? The 7950X will probably shyte on the 9900x as well.

Ι wasn't being sarcastic. For sure I'd buy a 9700X over 7800x 3d.

A win is a win. If an Intel chip isn't even a part of the conversation, it doesn't even matter which AMD chip you're willing to spend money on as long as there is one.
