Funny how GT2(4600) is faster in Synthetics (Vantage, 3D Mark 11) than GT630 but is almost produces half the frames in real games.
It seems that GT3 will have hard time beating GT630, and people expecting to be close to GT650 because of Intel’s 3D Mark 11 slides.
GT630: GDDR5 memory, bigger bandwidth, 50W just for the GPU
HD4600: Rely on DDR3 system memory, tiny bandwidth, smaller TDP available for the IGP, latency because the IGP have to communicate with the DDR3 system memory
It does fine in synthetic benchmarks, but once you hit the GPU with AA and other goodies, IGP will struggle.
HD5200/GT3 have dedicated memory on the same chip with much bigger bandwidth than GT630, so that will be a complete different scenario than this test
