Intel introduced a trio of embedded CPUs for SFF desktops and industrial PCs (IPCs), based on its "Skylake-R" silicon. This variant of Skylake features the largest integrated GPU Intel ever made - the Intel Iris Pro 580. This IGP features 72 execution units (compared to 24 on, say, the i7-6700K), and relies on a 128 MB eDRAM L4 cache for fast frame-buffering operations. The IGP uses this tiny yet fast cache, in conjunction with its traditional UMA system memory share, as video memory. The "Skylake-R" package is a multi-chip module of the main die with four "Skylake" CPU cores and the 72-EU IGP, and a second die housing the L4 cache.
Among the three "Skylake-R" chips Intel launched are the Core i7-6785R, the Core i5-6685R, and the Core i5-6585R. The i7-6785R features HyperThreading enabling 8 logical CPUs, 8 MB of L3 cache, and 3.30 GHz nominal clock speed, with 3.90 GHz Turbo Boost. The i5-6685R and the Core i5-6585R lack HyperThreading, and feature just 6 MB of L3 cache; the former features clock speeds of 3.20 GHz nominal with 3.80 GHz Turbo Boost, while the latter offers 2.80 GHz nominal with 3.60 GHz Turbo Boost. All three feature iGPU clocks of 350 MHz nominal, with up to 1150 MHz boost. The 14 nm chips further feature TDP of 65W, and feature dual-channel memory controllers that support both DDR4 and DDR3L memory. Sold in the OEM channel, the i7-6785R, i5-6685R, and i5-6585R, are priced at US $370, $288, and $255, respectively, per-piece, and in 1000-unit tray quantities.
