IGP Test Results
To evaluate the performance of Intel GMA HD graphics, we setup the i5-661 in
our standard motherboard test platform featuring a notebook hard drive, Blu-ray
drive, and Seasonic power supply. Our test results for Intel's previous flagship
IGP, GMA X4500HD were obtained using a 2.53GHz Core 2 Duo E7200. To make it
a more fair battle, we tested the i5-661 underclocked to 2.26GHz by lowering
the CPU's multiplier to 17x in addition to stock speed.

Like most modern IGPs, Intel's GMA HD had no problem rendering our video test
suite with low CPU utilization playing both H.264 and VC-1 content with the
CPU at stock speeds. Even underclocked by almost a third, playback was smooth,
though H.264 playback was more reliant on CPU resources than we usually see
when using Nvidia or ATI graphics. Power consumption was very low during playback.

Despite a 266MHz disadvantage in processor clock speed, the i5-661's GMA HD
required significantly less CPU assistance to play HD video compared to the
GMA X4500HD paired with a Core 2 Duo E7200. Either the IGP is more efficient
or the i5 processor is much faster clock for clock (or a combination of the
two). Power consumption was similar on both platforms.

GMA HD is also a faster IGP in 3D performance, with a hefty improvement onver
X4500HD in both 3DMark05 and 3DMark06. Its scores put it close to the GeForce
9300, but still aways off from the Sideport equipped HD 4200/3300 for AM3. For
older games at lower resolutions, it should be sufficient. Note that the i5-661's
GPU has a 900MHz clock speed while the other Clarkdales have to suffice with
733MHz.
