If gaming is one of those things that you do quite often on your laptop, you’d want a graphic card that can handle latest and greatest games without a hiccup. If you are a new entrant to this field, we suggest you check this post to get a basic idea about what to look for in a graphic card.

With current GPUs, laptops are no longer a save haven for the aliens in Crysis.

A quick look at the specs should give a clear idea about the processing power of most of the presently available chips.

However, comparing the raw specs doesn’t reveal much about their performance. A few benchmark scores would be able to tell the real performance difference.

The 650m stands as the leader of the pack with significantly higher performance. The ranking goes as 650m> 640m> 7730m>8730m>7730=7650>6770m> 7670m>7450m> 630m>620m(not shown in tests above)> 540m>7610m>7550m>7450m. 

From these results it is also clear that the 7650 is a rebranded 7730m. And as for Intel 4000 found on many Ultrabooks and laptops, wel,l it is a low end onboard solution with performance even below the 540m. It may run current games on low-med settings, but surely ain’t future proof. Hit the link if you wish to see how it scales against a few other cards. And the 610m, HD 7450 and HD 6490 are still even weaker than the Intel 4000. So best stay away from them.
