AMD as usual counting their mm2, be it in GPUs or CPUs. This company is too conservative.
If it were Jensen, you can bet he will have the fattest VCache, bigliest SLC and the widest CPU core possible.
Perhaps. It would cost 2x more tho ("CEO math"). Look at the xx90 graphics cards, chances are, he would not even sell you a fully enabled config for that, hah.

If Nvidia designed a CPU core you wouldn't be able to buy it.

They did (see Project Denver) at one point, but it was enough of a disappointment that they just decided to use the stock ARM cores (or do very little tweaking to the design) and use their superior graphics as a reason for customers to buy their SoCs. Qualcomm was really the only company that did sufficiently well with their own cores to justify the cost, and that was only until they floundered and also gave up on custom designs for a time.

I didn't see Denver nor Carmel in PCs.
Nvidia gave up on that effort until Microsoft and Qualcomm did the bootstrapping for them.
I'm not convinced that Nvidia CPUs would be better than AMD's without outsourcing the design to ARM (which AMD is also free to do).

True words about Jensen pricing, but regarding performance, even cut-down x90 part is more performant than anything AMD cheaped on.

Nvidia wasn't making their SoCs for PCs, it was for the phone/tablet market, which at the time was the hot thing, just like AI is now. Any ambition to replace x86 was just gravy on top as far as they were concerned at the time.

ARM was viewed as a low power CPU for mobile devices that could work where x86 (despite Intel's mediocrest efforts) couldn't operate due to the power requirements. That Apple managed to achieve ballpark similar results to desktop class x86 CPUs was almost viewed as a fluke.

AMD could probably build a great ARM CPU, but then they'd have to pay a license for each CPU. Like Nvidia they could probably get by competing as much on their GPU, but there's just not as much demand for that in the existing SoC market.

There's an argument the 7900 XTX isn't but the RTX 4090 has the ECC mode option in Nvidia's control panel. Pretty sure that's only enabled for "Pro" GPUs.

Anyway, Zen 5 and RDNA4 should be a great married couple.
Seems unlikely at this point.

If Strix Halo + Kraken make up the APU roadmap for 2025 then it's highly possible that the next APU in 2026 will just be Zen6/RDNA5.

Like Cezanne -> Rembrandt went straight from 7nm Vega+ -> RDNA 2, skipping RDNA1 completely in the APU market.

In games yes but in professional workloads, look at 7900 XTX in SpecWorkstation: https://me.pcmag.com/en/graphics-cards/19867/amd-radeon-pro-w7600
Despite that, thanks to the general software advantage of Nvidia i would argue that 4090 is more often than not better choice even for professional workloads, not just gaming.
I use it for archviz rendering. AMD cards are not even supported with my renderer of choice. In others, like Blender Cycles, they are like 2x-5x slower than their Nvidia counterparts. SpecWorkstation bench win for 7900XTX is nice, but its not neccesarily reflected in real world apps.

Admittedly though, i was bit harsh with my previous post. 7900XTX is indeed not bad GPU overall. I wanted to mostly point out that AMD could have blow Intel out of the water in the "client" space, if they wanted, same way Nvidia does to them with their x90 cards. But they are too busy counting mm2 and AMDs equivalent to Nvidias x90, aka something like Threadripper, is locked to different, more expensive platform. If Nvidia rolled like this, we would have x80 cards as top dogs and 102/202 chips would be available only as Quadros.

I agree, except there is one big difference in that Threadripper offers no additional gaming performance unlike the 4090 over the 4080.

'Lisa' didn't enjoy the hype train (+32%) ...

Her response ??

She sent us a frosted train (+16%)

(32 + 16)/2 = 24

At the end ... you will finally get the Pelham 24 train ...

... and most people will be quite happy with it ...


Are you just writing nonsense or do you state with certainty, that AMD will present us a 24% IPC increase?
