AnandTech visited Intel at CES and got to compare the Haswell's GT3e integrated graphics with a low-end NVIDIA GeForce GT 650M. The site wasn't allowed to report performance numbers because the hardware isn't finalized yet, but was able to compare DiRT 3 running at 1080p on both systems with identical quality settings. AnandTech says the two systems looked to deliver very similar performance.
The video below shows Dirt 3 running at 1080p on both systems, with identical detail settings (High Quality presets, no AA, vsync off). Intel wouldn't let us report performance numbers, but subjectively the two looked to deliver very similar performance. Note that I confirmed all settings myself and ran both games myself independently of the demo. You can be the judge using the video below:
Intel wouldn't let us confirm clock speeds on Haswell vs. the Core i7 (Ivy Bridge) system, but it claimed that the Haswell part was the immediate successor to its Ivy Bridge comparison point.
