Haswell: Up to 128MB On-Package Cache, ULV GPU Performance Estimates

Stefan Mileschin · 13th September 2012, 08:11

Intel was surprisingly quiet about the remaining details of Haswell at IDF this year. We know the rough CPU architecture details, some info at a high level about the GPU and of course the platform power improvements. There is a lot more however.

We already know that in its quad-core GT3 configuration, Haswell will offer 2x the GPU performance of Intel's HD 4000 (Ivy Bridge GT4). What Intel didn't say however is that Haswell's ULV GT3 parts will offer around 30% better GPU performance than Ivy Bridge ULV GT2.

The improved graphics performance comes both from an updated architecture and more EUs, but also an optional on-package cache of up to 128MB in size. It's too early to talk about SKUs and DRAM configurations, but 128MB is the upper bound. Expect to see tons of bandwidth available to this cache as well.

On the CPU side you can expect a ~10% increase in performance on average over Ivy Bridge. As always we'll see a range of performance gains, some benchmarks will show less and others will show more.
