Mozilla Webrender: rendering any webpage at several hundred FPS
I watched this the other day, and I've been mulling over the observation that onboard graphics are getting more and more die-space.On mobile, where discrete graphics are a rarity and power is a scarce resource, it makes sense to offload as much work onto the GPU as possible. 
Light it up, do the work as quickly as possible, then go back to sleep.However I started wondering about what can be done for high-end desktops. I just bought an i7-6700K, and of course it's paired with a very powerful discrete GPU.So as I understand it, effectively this means about 1/3 of that 6700K is just dark all the time. If there's any GPU work to be done it will all be offloaded to the PCIe bus, not the onboard graphics.How can we make use of that silicon in scenarios like that? Is there any advantages an onboard GPU has that can be leveraged over a discrete GPU? (Apart from power efficiency; which in my opinion is a non-issue when thinking about PCs with 800W+ power supplies.)---P.S: Of course all this would be moot if I had just bought the 5820K. Live and learn.
