It's easy. In game benchmarks, the CPU only makes a significant difference when the GPU is not the bottleneck (i.e. the difference between 120 fps and 150 fps). Consequently, dual-cores with the same IGP will have very similar FPS performance.
Yes, it is. The benchmarks show that it is better on average. Those are modern games that people are playing. If you have links to benchmarks which disproves, please provide.
Not true, bencmark show a significant increase in fps jumping from last gen intel cpus to current gen, in game bencmarks.
WHat do you think then the difference between two generations? Also the intel gpu scales very bad compared to a 320m. Turn the details to medium, and the 320m leaps ahead.
I dont understand why you talk about things you dont know anything about.
here are som real benchmarks
http://www.notebookcheck.net/Intel-HD-Graphics-3000.37948.0.html
Go down the list and press on compare, intel hd 3000, 50% worse peformance then a 320m
the demanding Anno, the Intel Graphics 3000 achieves 8.8 fps and surrenders at high presets (1280x1024, very high). Although you cannot play Anno at these settings, the integrated graphics chip from Intel indeed reaches the level of entry-level GPUs, which are at 9 fps (Geforce G210M) or at 10 fps (ATI HD 5470) not really faster
If you want more
Just ask
The intel 3000hd is being compared to the 210m. So yes, the intel hd 3000, if you just talk about gpus is a step back, a huge one aswel in many games. If people only had a clue what they talk about
