The new Core m7 picks up a bit more clock headroom, slightly faster DDR3 memory, and a higher maximum TDP (7W, compared to 6W). The lower-end parts, including the desktop chips like the Skylake Core i7-6700K, have 24 EUs. Intel’s Iris 540 GPU has 48 EUs, while the Iris 550 has 72 EUs. Intel hasn’t revealed whether Skylake Iris-class GPUs clock their EDRAM at 1.6GHz, like previous iterations of the technology, or if Intel trimmed clock speeds on the L4 cache to cut power consumption.Įxactly how much performance the new EDRAM will offer in this thermally and power-constrained environment is still unclear, but extra cache plus Skylake’s new graphics technology should offer significant improvements. Branding is also getting a bit of a shake-up - Skylake processors with Intel Iris Graphics will offer a 64MB L4, while chips with Intel Iris Pro (likely confined to the high-end TDP processors) will have the full 128MB. With Skylake, Intel is launching a 64MB variant of its L4, and including the technology on both 15W and 28W chips. Previously, only a handful of high-end laptop chips with 47W TDPs offered Intel’s Iris Pro graphics solution with its 128MB EDRAM cache. The big news for Skylake on the mobile front is that Intel is finally bringing its EDRAM hardware to lower-end, lower-power SKUs.
