Most attention Intel will give to the graphics core - increase the number of execution units and support the codec VP8.
One of the most noticeable changes will be 20% increase in the number of execution units. In core GT2 their number is 24 pieces, for GT3 - 48. Improvements at the architectural level is expected to increase the volume of the various caches graphics core, the best performance in operations tessellation and Z-buffering. GPU support twofold multiple sample antialiasing (2x MSAA) at the hardware level.
It also added support for VP8 SVC High Profile, and in the core GT3 and additional circuitry to accelerate algorithms Intel Quick Sync. Display Controller processors Broadwell operates at a higher frequency, which allows for higher resolution. In particular, when using the interface eDP 1.3 and DisplayPort 1.2 maximum resolution is 4096 x 2304 points (60 Hz) Processor Series H, 3840 by 2160 pixels Processor Series U. Series Y also the maximum resolution will be 3840 x 2160 pixels, but only one monitor, and its use leads to an increase in energy consumption. LVDS and VGA interfaces left GPU.
Broadwell graphics core can offer support DirectX 11.1 and OpenCL 1.2, Intel may also add OpenCL 2.0 and OpenGL 4.2 in some processors models .
