Haswell's GPU secret is Crystalwell

[Tenknics]

if i am not mistaken, i believe haswells gpu is based on knights fury?

actually awhile back charlie reported they scrapped LRB (and all its derivites) from haswell and any future cpu (for right now). Let me look for the article..But the GPU is just a super beefed up vers of whatever they've used for SB ( and in turn IVY).


He explained it in a recent article Ivy's GPU just has more of SB's EU 'shaders' and each shader is an ehanced version of SB's shader...So its a 2x increase with Ivy..And then haswell does that again but has up to 40 shaders, 5X performance...so basically brute force, better process and some cool new tricks...but def not Larrabee :/



Found it!

A year after that is Haswell, a new architecture on the same 22nm process as Ivy. Haswell is where Intel starts getting serious about die stacking, interposers, and related advanced packaging technologies...

We had originally stated that it was going to use Larrabee graphics on die, but that plan was pulled when Larrabee dumped the ISA of LRB1 and LRB2 for the new LRB3/Knights Corner ISA...
