Intel Corp.’s next-generation microprocessors code-named Broadwell will be made using 14nm process technology and will be more power efficient, yet will not be significantly different compared to existing Haswell products on the micro-architectural level. Nonetheless, the forthcoming chips will be quite different compared to the existing ones, according to the first details that have emerge on the web.


The first code-named Broadwell microprocessors for desktop personal computers will emerge during the holiday refresh (HR) cycle towards the end of 2014 in the form of so-called Broadwell-K chips aimed at enthusiasts. Just like existing Core i-series “Haswell-K” central processing units (CPUs), the Broadwell-K chips will feature unlocked multiplier as well as multiple adjustment knobs for enthusiasts to tweak performance. However, in addition to already existing functions and capabilities, Broadwell-K will also feature high-performance integrated graphics, according to CPU World web-site.

Current-generation Intel Core i7-4770K and Core i5-4670K microprocessors feature Intel HD Graphics 4600 (20 execution units at up to 1.25GHz) with moderate performance. Highest-performing Iris Graphics Pro 5200 (40 execution units with on-package eDRAM cache memory) graphics engine is found only on select CPUs designed for laptops and all-in-one desktops.

By contrast, next-generation Intel Core i7 “K” and Core i5 “K” chips that will belong to Broadwell-K generation will feature fully-fledged Iris Graphics Pro with high number of execution units with 128MB on-package eDRAM cache memory to boost graphics performance.

The most advanced current versions of Iris graphics engines support DirectX 11.1+ (with additional DX extensions), OpenGL 4.1, OpenCL 1.* as well as features like Intel Quick Sync Video technology, MPEG and JPEG decode acceleration, 4K UltraHD display resolution output, 3-screen collage mode display mode and so one. Next-generation Iris graphics engine will most probably be more advanced than existing ones. Perhaps, the new graphics cores will gain HEVC/H.265 decoder, OpenCL 2.0 support or new DirectX extensions.

Intel Core i7 “Broadwell-K” will feature four cores with Hyper-Threading and TurboBoost technologies as well as 8MB last-level cache. Intel Core i5 “Broadwell-K” will sport four cores with TurboBoost technology as well as 6MB last-level cache.
