Apple switching to AMD GPU for new iMac 5K

That's not right. The D300 is a modified W7000 (1280 stream procs, 256 bit bus) which is an £800 workstation GPU. The 265 is Curacao PRO with 1024 stream procs.

The GPU in all of them is Pitcairn which is a 1280 shader design - it actually says that in the link you posted!! :p

Edit!!

Curacao appears to be the same as the Pitcairn GPU:

However,since the R9 270 has boost and improved performance/watt over the HD7870,I suspect that Curacao is basically Pitcairn with boost enabled.

Looks like AMD are confirmed for iMac 5K

On the inside, the iMac with Retina 5K Display is powered by a 3.5GHz quad-core Intel Core i5 processor with Turbo Boost speeds up to 3.9GHz. It can be configured with a 4GHz quad-core Intel Core i7 processor with Turbo Boost speeds up to 4.4GHz.

In terms of graphics, the refreshed iMac desktop also comes with AMD Radeon R9 M290X graphics and can be configured with AMD Radeon R9 M295X, delivering what Apple claims will be up to 3.5 teraflops of computing power, 45 percent faster than the last iMac.

It's not surprising, AMD are desperate for any business they can get and are in no position to play hardball over pricing, Apple will be able to shaft them far than they ever could NVidia.

It's the same situation with consoles, both Microsoft (original Xbox) and Sony (PS3) have been burned by their prices in the past so AMD were always going to be the obvious choice.
 
Its good that AMD is getting these contracts to be honest as it takes a lot of the heat off the CPU race against intel (who we all know are dominating the miniaturisation race and have been for many years now). Getting squeezed on two technology fronts against two different companies isn't easy, especially in a billion dollar industry.

The iMacs seem to be specced for what I'd imagine they were designed for, photography and graphics design work. Definitely not a gaming platform, especially at that res lol.
