Ivy Bridge GPU Performance: Up to 60% Faster than SNB & Better QuickSyncby Anand Lal Shimpi on September 12, 2011 2:00 AM EST
This week Intel will begin sharing some of the first details of its Ivy Bridge processor (2012 Core i-series CPU) at the annual Intel Developer Forum in San Francisco. While the show officially starts on Tuesday, we have some early details about the chip.
Sandy Bridge was Intel's first high-end architecture to integrate a GPU on-die. The SNB GPU is available in two configurations: GT1 with 6 EUs (processors/execution units/cores) and GT2 with 12 EUs. All mobile versions ship with GT2 while most desktop parts ship with GT1. Intel calls GT2 its HD Graphics 3000 while GT1 chips come with HD Graphics 2000. There's a less featured version of GT1 that's simply called Intel HD Graphics as well and it's found in Sandy Bridge Pentium & Celeron CPUs.
Ivy Bridge's GT2 configuration has 16 EUs, no word on how many the GT1 configuration will have. As a result Intel is expecting a 60% increase in 3DMark Vantage scores (Performance Preset) and a 30% increase in 3DMark '06 scores. IVB GT1 on the other hand will only see performance increase by 10 - 20%. If we look at the 3DMark Vantage data from our Llano notebook review, a 60% increase in performance over SNB would put Ivy Bridge's GPU performance around that of AMD's A8. It remains to be seen how well this translates into actual gaming performance though.
The other information about Ivy Bridge's GPU has been known for a while: DX11, OpenCL 1.1 and OpenGL 3.1 will all be supported. The last tidbit we have is that Quick Sync performance is apparently much improved. Intel is privately claiming up to 2x better performance than Sandy Bridge in accelerated video transcoding or lesser gains but improved image quality. The performance improvements only apply to GT2 IVB configurations.
