AMD Zen 5 rumours

Right now, are there any desktop applications utilising the AI parts of these chips?
I know Windows 11 will soon, but having a dedicated AI section of a CPU just to harvest data and send back to Microsoft isn't really that appealing to me.

At the moment, it's feeling like just a way to slap an "AI" badge on. Which makes sense, as that's all you need at the moment. Just say AI and money flows.

As far as I know there isn't really anything using those cores that could be considered "real world". On phones AI cores are used heavily for photo and video processing, so maybe on PC Photoshop will use those cores

More gigabyte leaks

Confirm the new budget chipset is B840, it replaces B650 and interestingly it says B840 does not support OC. If you want to overclock you have to get a X870

Gigabyte confirms new B840 chipset: no CPU OC support and no PCIe Gen5 - VideoCardz.com

AMD B840 chipset replaces the cheaper B650 series Gigabyte leak has confirmed a new chipset for the upcoming AM5 Ryzen CPUs. AMD will introduce at least four new chipsets for its AM5-based CPUs. The X670E and X670 chipsets will be succeeded by the X870E and X870, respectively. The Extreme...

Though would require a new motherboard - something that spoils the whole AM5 long socket life argument. Will be interesting to see performance figures - assuming reviewers are commanded to use 8000Mhz EXPO kits for Zen5 and 6000Mhz kits for Zen4.

Of course we'll have good reviewers comparing Zen4 and Zen5 with the same speed memory, though may be few and far between etc.

My x670e board claims to support 8000mhz memory

Weird changes to the power limits as well

Apart from the 9950x, every other model has a significant reduction in TDP

Thats very interesting because with Ryzen 7000 they said they increased TDP to get max performance, now they are backtracking.

Will be interesting to see if the 9900x, 9700x and 9600x run at lower clock speeds than the 7000 series models.
I believe they will, but will still be faster because of its higher IPC. What gives me more confidence they will is that the 170w 9950x is advertised as the same clock speed as the 7950x, so if the other models have lower TDP, they must have lower clocks than the 7000 series.

  • Ryzen 9 7950X (170W) -> Ryzen 9 9950X (170W)
  • Ryzen 9 7900X (170W) -> Ryzen 9 9900X (120W)
  • Ryzen 7 7700X (105W) -> Ryzen 7 9700X (65W)
  • Ryzen 5 7600X (105W) -> Ryzen 5 9600X (65W)


I've got the impression that Ryzen 9000 is just a small stop gap generation, the real meat will come with Zen 6 I guess

And AMD has announced that they will continue launching new CPUs for AM5 until 2027.

AMD's original commitment for AM5 was only until 2025 and now they've extended it through to 2027

AMD says the Ryzen 9 9950X is around 13% faster in gaming than a Core i9 14900k. This means the Ryzen 7 9700X and Ryzen 9 9950X won't be massively faster than the X3D parts:

It's not too hard to find a Ryzen 7 7800X3D for around £300 now.

It's worth noting that according to AMD's slides they tested the 14900k using Intel's new default bios power profile, which reduces the 14900k's performance, including in games, by 10% compared to that benchmark you posted which was done using a much higher TDP profile.

So realistically the 9950x has the same gaming performance as a 7800x3d at best and at worst, slower, and that's why AMD only showed gaming performance vs the 14900k and not vs Ryzen 7000.

In the only AMD vs AMD gaming benchmark shown, AMD said the 9950x is 10% faster than the 7950x in Far Cry 6. But the 7800x3d is 19% faster than the 7950x in this game, ergo in this particular game, the 9950x is slower than a 7800x3d

Zen5 has the lowest Gen on Gen performance increase of any Ryzen so far

Is AMD holding back or are we past the peak and riding into the sunset with Zen, is the architecture approaching a tank with little left to give?

One other interesting bit I noticed; desktop Zen5 has no NPU. The laptop Zen5 APUs do have the NPU, but desktop doesn't, where as Intel is including an NPU in its desktop Arrow Lake CPUs

I knew something had to give with that TDP reduction and I found it

Ryzen 9000 CPUs run lower base Clocks than Ryzen 7000. While AMD advertises the same single core boost clock, it's likely that Ryzen 9000 CPUs run at lower all core clocks than Ryzen 7000
 
Am5 sales were extremely slow at the start, so slow that many large retailers in the US were offering free memory, store credit, vouchers and other free items for buying an am5 board and cpu to clear their over stock


A lot of the poor AM5 sales was AMDs own fault. When AM5 and Ryzen 7000 launched, there was almost no reason for a gamer to buy in - the gaming performance was no better than a 5800x3d, ddr5 memory was double the price of ddr4 and why would you buy a new motherboard when you get the same game performance with your existing am4 and a 5800x3d

Intel still ahead on Steam hardware survey. I'd have expected AMD to have made more headway, considering that Zen4 and Zen4X3D have been leading the gaming benchmarks for years at this point and are clearly superior.

It's cause AMD does poorly with laptops and OEM PCs
