Something is off.

is 8840 not 8040

The 8840U belongs to the 8040U family.

There is no 8040U specific processor in existence, it refers to the family of processors.

I though that that was general knowledge in the IT world, but I see it isn't (or maybe it is, but...)

QuoteGPD is all set to upgrade the AYANEO

GPD and Ayaneo are two competing companies.

So Valve getting AMDs left over chips is kind of like how Nintendo got Nvidia's left over Tegra X1 chip that nobody wanted but they'd stockpiles of for the Switch.

Apparently, the way it really went down is the SoC was originally built for MS for some Surface like device. Then they delayed and cancelled it. Later on Valve came along and AMD offered to give this chip at a discounted price as otherwise the SoC project would of been a complete waste of money and resources (designing semi custom silicon takes a ton of R&D).

Well, Van Gogh was a power optimized chip built from ground up for ultra low power devices. Z1 Extreme is marketed for handhelds and according to AMD's own revenue earning it's counted under the sales of 'semi custom silicon division' but it's a lie. The Z1 Extreme is a 7840U. They basically shoved a laptop chip into a handheld, which is kind of mind boggling. I mean, no sheet, it'll have terrible battery life.

Another way it could be seen is, AMD's GPU division only gets serious and don't duck things up when big money console contracts are on the line. Notice the gens that are pretty good (e.g. Polaris, RDNA2) are all used in consoles too and the ones that aren't (e.g. RDNA1, RDNA3) are simply used for beta testing on the PCMR?

Rumor has it that both RDNA3.5 and 4 are gonna be lackluster as the next-gen consoles will be skipping those to be based on RDNA5, so AMD can't really afford to screw that up. But I guess we shall see.
