CPU World are reporting on Broadwell's GPU.

Broadwell, as I'm sure most people know by now, is due this fall for mobile devices and laptops, while we have to wait until 2015 for performance CPUs for desktops, including an unlocked one with Iris GT3e.

A sample:

Broadwell graphics is based on 8th generation architecture. One of the most important improvements in Broadwell GPUs is 20% larger number of execution units, that is 24 EUs for GT2 chips, and 48 EUs in chips with GT3 graphics. On top of that, the architecture was optimized for greater performance. The list of improvements includes increased size of various GPU caches, better Hi-Z and tessellation performance, and increased Pixel clock fill rate. The GPU natively supports 2x MultiSample Anti-Aliasing in hardware.

The big news is the 2x MSAA via hardware, excellent approach from Intel, that will solve their bandwidth issue with higher IQ.

Reminds me of the old Rendition Verite which had hardware AA built in.
