While the MacBook air refresh of 2013 has already taken place, and they already feature Intel's new Haswell processors, the MacBook Pro (Retina) lineup still has to be refreshed. The folks over at MacRumors have published a screenshot of GeekBench, and it shows some interesting details.
For starters, it appears that one of the units will feature an Intel Core i7-4950HQ. This CPU will run at 2.4 GHz and has four cores, but with hyperthreading features 8 threads. Most notably though, this CPU features the GT3 iGPU, which features twice the number of graphics processing cores as the lower-power units. It features 40 processing cores and is otherwise known as the "Iris" 5200 graphics part. That said, while it might be a nice development to have more powerful Intel graphics for power-saving reasons, the GeekBench screenshot makes no mention of a dedicated GPU, which if correct, means that the next generation of MacBook Pros might have to settle with only the internal graphics on the Intel Haswell CPU. The current generation of MacBook Pro Retinas feature an Nvidia GT650M graphics card, which would still be much more powerful than the Intel Iris graphics part.
Apple is generally using that to differentiate the two.
Ha, getting a Mac for the price, never though I'd say that.
The performance is impressive, especially considering the 47W TDP of the total package. However Iris Pro isn't quite good enough to challenge the GT650M in current gen Retina Mac Book Pros. It's close, but I wonder if Apple is willing to sacrifice a little GPU performance in its top-end notebook, even if it means greatly improved battery life.
