The term GPU was first coined by Sony for the PlayStation with its 3D capabilities, and has been associated with 3D rendering since. In some products it stood for Geometry Processing Unit, again referring to 3D. Purely 2D graphics coprocessors generally don’t fall under what is considered a GPU.

It has been associated with 3D rendering, but given that things like the S3 86C911 are listed on the Wikipedia GPU page, saying "Accelerated GUIs don't need GPU" feels like attempting to win an argument by insisting on a term definition that is significantly divergent from standard vulgar usage [1], which doesn't provide any insight to the problem originally being discussed.

[1] Maybe I've just been blindly ignorant for 30 years, but as far as I could tell, 'GPU' seemed to emerge as a more Huffman-efficient encoding for the same thing we were calling a 'video card'

I don’t agree with what you state as the vulgar usage. “Graphics card” was the standard term a long time, even after they generally carried a (3D) GPU. Maybe up to around 2010 or so? There was no time when you had 2D-only graphics cards being called GPUs, and you didn’t consciously buy a discrete GPU if you weren’t interested in (3D) games or similar applications.

In the context of the discussion, the point is that you don’t need high-powered graphics hardware to achieve a fast GUI for most types of applications that WPF would be used for. WPF being slow was due to architectural or implementation choices.

That's the real takeaway - WPF should have degraded gracefully (read, full speed performance without the bling) but it didn't.
