News AMD boosts Zen 5 official warrantied TDP to 105W, fixes Ryzen 9000 latency issue, launches 800-series chipsets

[Admin]

AMD made a slew of announcements about its latest progress with its Zen 5 Ryzen 9000 processors, with the most important announcement being that the company will now fully support a 105W TDP mode with its Ryzen 5 9600X and Ryzen 7 9700X models.

While this will improve performance for applications that can utilize all cores, this will not help gaming performance if that is important to you. For gaming both the 7700X and 9700X were drawing the same PPT (70W vs 71W) while gaming. That means that the 105W TDP won't help at all as they CPU is still within the 88W PPT currently.

@PaulAlcorn Thanks for the article, are you planning to benchmark Zen4 and Zen5 CPUs to gauge how much performance has been gained through the Windows 24H2 patch?

While the 105W profile isn't universally necessary I certainly appreciate AMD adding it and covering it under warranty. Technically speaking PBO violates the warranty so it's never great to be in a gray area should you end up having problems under warranty.

There's a link in this article to a piece they did testing the KB which was released for 23H2 which adds those optimizations: https://www.tomshardware.com/pc-com...md-performance-gains-from-windows-23h2-update

I can imagine AMD wanting to restrict its new 4nm chips to 65w after Intel has performed a perfect "10" of a faceplant with its ringbus burnout issues on 13900 and 14900 CPUs. Now as the leader in Desktop CPUs, a lot of responsibilities are falling to AMD, such as revealing and identifying Microsoft's blunders and mistakes in their operating system, which wreck performance. It's lonely at the top!

What I'm shocked about is that the CPU designers have heavily upgraded the Ryzen 9000 CPUs but there is no thought to improving the ram drivers or switching fabric to make the whole system go faster ... seems like a major oversight by the overall system architect, 3000 Mhz and 2:1 infinity fabric speeds wtf? Same as 7000 wtf? They completely fumbled a chance to improve the 9000 CPUs by at least supporting up to 3600 Mhz and 2:1 or something!

The 9000 series uses the same IO die as the 7000 series so that was never going to change.

There is nothing wrong with the 9600X and 9700X in 65W TDP mode. They offer similar or better performance than the previous generation that required 105W TDP. Now you have the choice to go with a 105W TDP. If you need it you have that choice to make to gain extra performance WITHOUT voiding your warranty. If you don't need it then you can keep the advantages of the 65W TDP.

Well it was widely known Zen 5 was same old F and IO die. Zen 6 is basically about fixing all that is wrong with dual ccd's, moves to 3nm IO die, hopefully much faster IF. No use releasing more cores when even 7950X is bandwidth starved. AMD needs to get 7200MT/s memory as sweet spot and support 10000MT/s+ in 2026.

Is 60% higher TDP and 10% more performance really something to brag about?

It's about option. Wow, you really missed that point? If you want that free 10% you can opt for it and still be covered under warranty....

That doesn't seem to hard to understand.

Plus, that's how it is with all CPUs. The percentage of performance goes down with the higher power draw. That's a know thing also.

That doesn't seem hard to understand either.

So now we all have a choice. Wanna focus more on efficiency... Leave it as it is.

Want to have a bit more performance, check the box and your good to go.

Seems like free performance is a good thing.

Imagine driving 10% faster and your mpg drops by 60%.
This not a being a very good trade doesn't seem too hard to understand.

Where does the idea that it's bandwidth starved come from? It has twice the bandwidth of 5950x and only 40% extra performance.

Imagine wanting to get somewhere faster, you can spare that extra mpg for that specific occasion and the go back to driving normally. That's why it's optional. Amd isn't forcing you.

After all, with 105W being not the "plan A" of AMD for its Ryzen 9000 chips, it's quite obvious that this much of power draw is most certainly well past these chips' optimal voltage-, current- and frequency-tuning.
In other words: the chip becomes increasingly less efficient as more power it sips beyond its original designation.
So, it seems to me that AMD is trying to pull an "Intel" move here and to make up for some performance gaps by brute force, regardless of efficiency and the chips' optimal power states.
This in turn may negatively impact the longevity of the Ryzen 9000 CPUs when they have to run outside their architecturally optimal curves.

Fundamentally you are right but I do greatly prefer the AMD choice of keeping the more efficient TDP as default.
What was wrong is the fact that AMD forgot the 105W options at launch.

This in turn may negatively impact the longevity of the Ryzen 9000 CPUs when they have to run outside their architecturally optimal curves.

Nowadays nobody is scared by a 105W TDP, and however, the most important thing to do for longevity, is to keep temperatures down.

(moreover, 4 pcie lines gen 4 = 64Gbps, not 2x40, but the is two DP links to complete the bandwith)

Wrong. What AMD has done is enable easy overclocking for those wanting to do so.

Easy overclocking was already a thing with PBO. IMO this isn't as much of overclocking a cTDP.

Ha! That comparison is meaningless. The amount of power used in a PC isn't comparable to a gas powered car.

Seems to me you're just trying to find something negative to say about the CPU.

If you want to save on power just don't use it!!! Simple!!!

Same with a car, if you want to go there. If you want to save on gas, don't floor the throttle! But it's there if you need it or want it.

So you still have a problem. You don't have a valid point.

I do however, all I said is you have options. Guess what... That's exactly what this is! Nothing incorrect about it.

I'm all for flooring it and getting terrible gas mileage, but if going from 50 to 55 dropped my mpg by 60% I'd be taking the car to the shop!
