Review: AMD Ryzen 9 7950X3D processor

Absolutely fantastic performance and efficiency. Shame no x3d sku will be near 300e or even 350e, would love to see a 7600x3d at 300. Not a product for me, games aren't good enoughh these days for me to spend +400eur on cpu alone, though the product itself is worth it for an enthusiast. I hope those who buy it will enjoy it.
Intel need to drop 13600K down to 250 after 7800x3d comes out and I'll be happy too, it's not like the difference is huge. It's 14-16% even against a non-oc'd 13600K with stock memory at HUB, so worst case scenario for intel.

 

This 100%! Need some bog standard PCs with these CPU to show the real world value.

 

Can't wait to see 7800X3D reviews for just one thing:

Comparing it to a 5800X3D platform, and seeing that you can actually save a third for a lot more than just 70% of the FPS... probably close to 90%.
When your 5800X3D platform costs as much as the new CPU alone

 

Power efficiency of these CPUs is very impressive, especially when compared to the 13900K.

 

Power consumption is a very pleasant surprise, the 7800X3D looks like it's going to be a great chip.

 

It's the only surprise, so far.

 

Even with work applications, the power efficiency of the 7950X3D much more efficient than the 13900K.

 

Yep 7950X3D's power efficiency is extremely interesting (except of idle), but what I find even more interesting in these graphs is power consumption of 13900K, which is nowhere near to what I see. Especially their claimed average gaming power consumption of 143W is just ridiculous (with 13700K having 107W??). The highest peak I've ever seen in any game was in WD:Legion and that was 120W. On average in games it's closer to 80W.

 

They are testing power consumption with a 4090 at 1080p, pretty much pushing the CPU to the limits, at 4K Ultra the power consumption would be much lower for all CPUs.

Overall the 7950X3D just tie with 13900K at higher efficiency, and higher price, nothing to drive home about

 

Excellent review as always @Hilbert Hagedoorn. I've made so many informed decisions on hardware purchases based on your analysis. Thank you.

I am thoroughly impressed with the power consumption of the 7950X3D. The game performance wasn't the increase I expected but still impressive nonetheless. I really want to see how this processor performs with future UE5 games and other game engines that are coming. I definitely foresee new software that will excel with the extra cache the 7000 series X3D chips provide. I'm a 4k and above style gamer. While the GPU handles the workload especially at high resolutions we still "sometimes" see benefits from faster CPUs. For now, I will be keeping my 7950X because it's an excellent workhorse.

I agree with @nizzen a ton! The 7800X3D will be extremely popular and will be sold out when it's released.

 

If the 7950X3D was released at $550.00 and the 7800X3D $399.00 MSRP.............My goodness! All forums would be joyous!

I paid $550.00 for my 13900k back in October. Just sayin.............

 

and that's just the 13900k... the rock ribbed hard point is a 13600k & a b760 mobo can be had for $500 for both. (US)
so the entry level enthusiast has a tough choice between 7600X/b650 & 13600k/ b760 at that price point.
right now G.Skill has excellent DDR5 6000 (both EXPO and XMP) @ $135 for 2 sticks @ 16Gb (32Gb), so that differential is nil, but not if the Intel buyer gets a DDR4 set.

regular enthusiasts have the CPU sweet spot (pricing) between 400-600 anyways so they will flock to 7800X3D
but imho, the budget market favors Intel (1st time in a long time)

 

Except AM5 board's insane prices. Where I live I can buy Gigabyte z790 Aorus Elite board + 13900k for about the same price as the x670e equivalent and a 7700X. The 7800X3D will be even more expensive. AMD is not making it easy to switch :/

 

Agree 100%.

The 5800x3d may set the record as AMD's best selling chip over the next couple of years.

Like some have alluded to already, you don't need a 13900 or 7900x to run a game today.

 

Don't think so - how "long" term do you mean by your expression. I think a 13900k / 7800x3d is at 20-25% CPU load at 4k in most games with a 4090.

Even is you double GPU performance every generation (which is utopia) you look at 6 - 8 years which a 5800x3d or 7800x3d or every other "better" CPU is worth it. And hell in 8 years (if PC gaming should be a thing by then) enthusiasts will game at 8k 100 FPS because its pretty. And out of competitive gaming you will never need more then 120/144 FPS

 

I would consider the X3D, but I have an expensive water cooling with a 13700kf at 5.6 1.29v. If I was to go back to air, I would definitely get Ryzen this time around. But that fact I can't OC I stay with intel. However, I am considering Ryzen for sure in 2 years.

 

only point i feel i have to make is that Z790 is not the same as X670E. it's equivalent to X670, which is $200 saved right there.

tbh, i would take your point to B650 vs B760 as "no one needs" Z790 or X670 to game. there the price differential is $10-20 in Intel's favor
but neither one is a "barrier". right now the biggest differential are the price cuts on 5800X3D, which is more than the DDR 5 and mobo differential combined. so that really makes it hard for anyone on a budget to go AM5

 

I understand, but that still doesn't explain that huge 34% difference to 13700K. 8 e-cores can't do that much on average. I suspect that they didn't check their BIOS and actually made these tests with unrestricted power settings... which is default for most MBs.

 

Fantastic review, guess i now know everything.
I don't know why I should buy a 7950X3D over a 13900K.

Guess power consumption really is the key element that differentiate the two.

 

the 13900k has "Adaptive Boost Technology"(ABT) which is basicaly a more aggressive boost algorithm , where as the 13700k doesn't, also the ecores, once the are clocked outside of their efficiency curve (which is basically done all raptorlake parts) , they consume significantly more power. 8 ecores is nothing to sneeze at. its like adding a whole coffeelake 8core cpu that is under clocked.

edit: some graphs from anandtech about ABT
i7

i9 with abt enabled

as you can see particularly when using more than 4 cores , it can have a pretty big impact.
