AMD Ryzen 7 9700X

Just increase the TDP then, it's probably power starved.

It isn't. At least not in gaming. Other sites like German ComputerBase have tested this and upped the power limit from 88W (default 65W TDP) to 142W (same PPT as the 7700X). The 9700X achieved +1% better results on average (+3% best case), i.e. at least for games it is completely pointless to run this CPU at a higher power target.

Most games aren't CPU limited, and where you have those issues it would probably make some more difference with the extra TDP. I was talking MT applications.

Just to be clear: They ran those PPT benchmarks at 720p to make sure the CPUs could run as freely as possible.

 

[Jonny5isalivetm5]

Can someone just confirm the idle power usage ? is it really super super high ?! my 12900ks is around 5-10watts :E

 

[R0H1T]

And like I said before this when talking about CPU performance uplift do not include games in there, games are still primarily affected heavily by GPU ~ they are a measure of your GPU largely.

Just to be clear: They ran those benchmarks at 720p to make sure the CPUs could run as freely as possible.

There was this term "gaming IPC" floated around a while back, not sure here or AT, but think of how absurd that is?

 

[TheDeeGee]

Just wait for Arrow Lake....Intel upped Max. to 105 deg. Be interesting to see if it bounces off 105 constantly after 40-60 seconds like Raptor Lake.

I use 65 Watt CPU's so i'll never see such temps.

95C on a 65 Watt CPU is just weird.

 

[R0H1T]

I know fev brought that up often!

95C on a 65 Watt CPU is just weird.

Depends on cooling, ambient and your case. I wouldn't say weird just not desirable.

 

[GhostRyder]

I have been reading a few reviews across the internet and I think alot of people are missing what makes these chips interesting. In its stock state these things sip power especially compared to the Intel equivalent. Its not going to beat the 7800X3D in gaming but we knew that, its not crammed with cores for heavy multi-tasking, and its not even the top end part. Realistically we need to see what the top end does (Ryzen 9) to see how those hold when the limits are removed.

I am curious how the Ryzen 9's will do.

 

[TumbleGeorge]

It's not a question of whether the processor deserves the next-generation designation or not. The Zen5 microarchitecture is completely new from scratch

You'll wrong. Just some works on frontend.

Disappointing, but it can be fixed - bump single thread boost and offer an application with quick switch profiles - 45W (Eco Mode), 65W (Standard Mode), 95W (Performance Mode), 120W (Ultra Performance Mode).

 

[Dr. Dro]

Performant is not a word in english, do not use it!

It is only in french and Linus uses it because he is from Canada, country of snail-eating ancestry, and because he is confused.

performant

1. (of technology, etc.) working in an effective way: 2. (of technology, etc…

dictionary.cambridge.org

Might be a borrow word, but it does exist and is in the dictionary

It looks like they went pure power efficiency this generation.

It seems to be the same node or a similar node to what Nvidia's been building Ada Lovelace with. It's super efficient indeed.

I question the utility of going above its 88 W PPT. I expect the 9950X review to prove it

 

[Frick]

The price on the 7800X3D is likely to drop a ton when the 9800X3D comes out, presumably later this year.

Me I'm holding out for an affordable 5x00x3d.

 

[Dr. Dro]

Me I'm holding out for an affordable 5x00x3d.

5700X3D is probably at its all-time low right now, IMHO. It's probably gonna begin to rise in price as demand increases, 5800X3D is already suffering from that. I think it's a good time to buy, man.

At stock, its temperature doesn't exceed 61 C in the review that we are commenting on.

 

[cellar door]

What MAGIC?

ya know.. the review was done by a w1zzard - does that answer your question

 

[RandallFlagg]

You'll wrong. Just some works on frontend.

No, there are a ton of uarch changes vs previous gen to gen changes with Zen.

The *big* change is wider pipelines. There are many others though and it's very significant.

This is why the performance issues might be compiler related. If so (and I think it pretty likely), then Zen 5 may see big bumps in performance as compilers are updated to make use of the uArch changes.

GN has a good write up here. Again, these are pretty extensive, it's really much more of a change to the uArch going Zen 4 -> Zen 5 than Zen 3 -> Zen 4.

Zen 4 was really much like Zen 3 with support for DDR5 and PCIe 5, which in and of themselves are not really uArch changes.

BTW this gives Intel a slight chance for their upcoming CPUs, they may be better than these Zen 5 chips.

Until the next X3D chips launch

 

[TheinsanegamerN]

Disappointing.
If you take the 7700 for comparision, since they have the same TDP, there is less then 10% difference, sometimes even under 5%.
But I get a 7700 for almost half the price of a 9700X...

I'm with you. There's a lot of POTENTIAL here, with the wider front end, impressive single core performance, and lower power use. But potential doesnt mean benefit, it may take years before the benefits of zen 5 show up in real benchmarks.

What I see is that the average shows a 4-5% increase, which just doesnt justify a purchase.

It looks like they went pure power efficiency this generation.

It's a good selling point, especially if arrow lake turns out to be another amp chugger.

 

[Carillon]

I guess the 9800x3d will be unlocked to match the 7800x3d, but without needing an external clock generator. Yay.

 

[TheinsanegamerN]

Me I'm holding out for an affordable 5x00x3d.

Those were ~2 years ago, when you could get one below $200. I grabbed mine for $179 on sale.

Now they're almost back up to launch MSRP, and with ryzen 5000 production lo longer the priority, I wouldnt count on it getting cheaper again.

If you see it or the 5700x3d anywhere near $200, grab it immediately.

It does make the difference
From 9:23

 

[RedelZaVedno]

Why would anyone buy 9700x when he can get 7800X3D for 350€/$?

Pricing makes no sense. It should cost 300 bucks max imho.

 

[persondb]

What? Did you actually check the review or other sites?

AMD Ryzen 5 9600X & Ryzen 7 9700X Offer Excellent Linux Performance Review - Phoronix

www.phoronix.com

You should read the actual review and see that they are very different. Phoronix focus on a lot of server and HPC applications, that will have a skewed result due to the full AVX512 implementation. As an example, they have 5 SIMDJson benchmarks, which to nobody surprise benefits a lot from having better SIMD throughput, same for Numpy, crypto, tensorflow and etc.

So their result is more indicative if you want to use a 9700X as a home server or something.

 

[evernessince]

It looks like they went pure power efficiency this generation.

And yet they are still loosing to the 7700 and 7800X3D in power efficiency. It's only better than 7000 series chips that are pushed way out of their sweet spot.

Either they have made very little progress in terms of efficiency or none at all.

The same could be said about the processor as a whole, not much worth mentioning. As other's have stated this seems more like a Zen+ than a new architecture.

For AMD's sake this processor better be laying the groundwork for a large next gen uplift because in every other metric it's an abject failure.

 

[Vincero]

It isn't. At least not in gaming. Other sites like German ComputerBase have tested this and upped the power limit from 88W (default 65W TDP) to 142W (same PPT as the 7700X).

That's disappointing in the sense that it would seem that there isn't much more headroom - either there is some other inefficiency or it looks like 4nm vs 5nm is really a minor bump / offers no extra headroom.
