Irish Pro Graphics vs 650M vs 750M

Hello Shadow82x,

It's a good question, i was also wondering this, so i did some research.

What i found out is that the iris pro graphics is the least and the 650m and 750m are similar. The 750m is an rebrand of the 650m but with higher core clocks and memory clocks what results in an 10% performance boost in certain situations.

Here are some benchmark results:

Unigine valley 1.0:

Iris pro 16.9 fps

Gt 650m 33.8 fps

Dirt 2 High settings 1680x1050:

iris pro 28.5 fps

Gt 650m 47.3 fps

As you can see the Gt 650m clearly outperformed the Iris pro and you can expect that the 750m has around 10% higher scores.

(in the Youtube link below there is an comparison of the 650m model against the iris pro model)

Hopes this helps you out!

Basically you're not going to be running Crysis3 at max with either.
