The Intel HD Graphics 3000 is an integrated graphics card which has no dedicated memory but shares the Level 3 / LLC Cache with the CPU cores and also part of the main memory. While the AMD Radeon HD 6470M (or ATI Mobility Radeon HD 6470) is based on the Seymore XT core which offers a 64 Bit bandwidth of dedicated DDR3 memory. Both of them has the capability of decoding and encoding HD videos. Theremore, thanks to AMD’s HD3D Technology, the HD 6470 users can watch 3D movies, which the Graphics 3000 cannot. And the Intel’s is not capable of drive up to 4 monitors simultaneously like the AMD’s can do (using the eyefinity technology and enough displayport outputs).
Comparing this two different kind of graphic card should be easier when it comes to game test. The game includes some older and latest games, and all settings are settled In low detail and 1024×768 resoution display. The HD Graphics 3000 was faster than the HD 6470M very few games, like CoD 4 – Modern Warfare and Left 4 Dead. In Half Life 2 and Counter Strike: Source the AMD Graphics stayed a bit behind. The rest of the game tests, including Dirt 3, Crysis 2, CoD Black Ops, FIFA 11, Starcraft 2, Metro 2033, Battlefield: Bad Company 2, CoD Modern Warfare 2, Resident Evil 5, NFS Shift, Dirt 2, Anno 1404, Sims 3, F.E.A.R. 2, and Crysis, are dominated by the HD 6470M on average 20% of framerates per second. So, overall the AMD Radeon HD 4670 is faster than Intel HD Graphics 3000 in gaming performance.
Some other test, like 3DMark, PCMark, and Chinebench also showed the same outcomes where AMD Radeon HD 6470M beated the Intel HD Graphics 3000. Same as the Windows 7 Experience Index gaming graphics test result which the Intel’s and the AMD’s have 6.1 and 6.3 point respectively.
Due to 32nm technology of the Intel HD Graphics 3000 and 40nm technology of the AMD Radeon HD 6470M, both of them consume a tiny bit of power. Therefore, they are suited for a small and light laptops.
