Benchmarks: IGP - Part One

3DMark Vantage provides a good overview of combined CPU and GPU performance. Clearly, this is an area in which Intel has taken giant strides. Core i7-4770K marks a 180 per cent improvement over Sandy Bridge, and a 40 per cent improvement over Ivy Bridge. Intel's latest remains at the top of the chart, but to get a true feel for IGP performance, we need a more demanding 3D load.

3DMark 11 does a much better job of stressing the IGP and helps paint a clearer picture. The HD 4600 built into the Core i7-4770K delivers almost twice the performance of the Core i7-3770K's HD 4000. A marked improvement, though still not enough to match the Radeon HD 7660D baked into AMD's latest APUs.
Remember, Sandy Bridge doesn't include a DX11-capable IGP, hence the lack of results.

Intel has certainly closed the gap on AMD as far as IGP performance is concerned, but the HD 4600's enhanced capabilities leave us longing for more. If this middle-of-the-pack IGP can return over 900 3DMarks in the demanding Fire Strike test, what might a top-of-the-line Iris Pro 5200 with twice the number of execution units and a dedicated frame buffer achieve? It's a shame that self-built desktop users will never know.
