Nope, intergrated, are shockingly not described as discrete, theres intergrated, and discrete, thats it. AMD have 42% of discrete, Nvidia have 51% or so right now with the swing towards AMD pretty much happening for 2 years straight, but progress in these situations(not least when you don't produce your own stuff) is slow.
In terms of the complete graphics market, Intel run about 50% of every gpu sold when including everything.
Mobile: AMD 9.1 million parts vs nVidia's 9.2 million
DX11: AMD shipped 3.9m parts in Q1 vs 1.575m in Q4
Discrete: AMD shipped 15.95m (42.1%) versus 21.9m (57.8%)
Total: AMD shipped 25.4m (20.2%), nVidia at 33.05m (26.3%) and Intel 65.5m (52.2%)
Intel = the graphics daddy, and they don't sell a single discrete card........ yet
When you look at whats discrete and whats intergrate, hmm, its actually hard to know, I think the mobile numbers are intergrated and discrete, just anything in a laptop. Which puts AMD's intergrated sales at 25m - 16m discrete = about 9 mil. Nvidia still sell a lot of intergrated and the vast majority of the rest, is low end sales gt210-220's, less so but still large sales of things up to gt240's. Most of that segment, intergrated and low end sales is probably, I dunno, at least 15mil of AMD's sales, and probably 20mil or more for Nvidia.
This is Nvidia's problem in the future, intergrated, gone, chipset, gone, low end(and thats the killer yet to happen), gone.
In 2 years those market share numbers are going to be a very odd picture to say the least.
If Intel get a half decent on die gpu, they'll get a ridiculous portion of Nvidia's lost sales, if Intel can't make anything good and AMD stuff something 4 times more powerful on die than Intel can manage, they might take a hefty chunk of Nvidia's lost sales.
The problem is with Intel running roughly 82-84% of the market right now, that means 80+ of the low end discrete market, is in Intel rigs, so if most of them simply move to Intel on die low end gpu's it makes sense that 82-84% of Nvidia's lost sales will move to Intel.
If AMD's on die gpu is "that" much better though, it could really help push their cpu sales up against Intel aswell as getting more "gpu" sales.
