Continuous-integration testing for Intel graphics

Would that be much better than simply buying a whole new processor? See e.g. https://cdn.arstechnica.net/wp-content/uploads/2015/01/Sc... ("5th Gen Intel Core Processor Die Map") - the GPU itself is about two thirds of the silicon area when paired with a dual-core CPU, plus the CPU and GPU both need the 'shared L3 cache' and memory controllers etc, so just removing the CPU cores looks like it would save very little cost. (It seems these chips essentially are graphics chips already, with a few minor peripherals like CPU cores stuck on the side.)

Then you'd need to add gigabytes of dedicated VRAM to make it work as a discrete card. And in terms of performance the current highest-end Intel GPUs would still only compete with perhaps a $70 NVIDIA card, so it doesn't seem there's much opportunity for profit there.
