- wmf 13y agoLast year there physically wasn't room for a discrete GPU in the 13" and this year there still isn't.
- gutnor 13y agoAnandTech tested the IRIS Pro 5200 to roughly on par with the 650M (last generation MBP), with obviously significantly better power management. For Intel, that is quite an achievement. But it is just quite a bit too short for Apple to get rid of discrete graphic completely. For the type of graphic performance that Apple put in its laptop (medium range), it is likely that Intel will catch up in a generation, maybe 2.
- andor 13y agoThe Iris Pro 5200 has 128MB DRAM ("Crystalwell") embedded in the CPU/GPU package. This one is in the 15 inch model. The Non-"Pro" Iris 5100 in the 13 inch Macbook is the same GPU, same clock speed, but without the embedded DRAM. Depending on the task, the 5200 seems to be up to twice as fast. Also, the DRAM is actually a huge Level 4 cache for the CPU, which means that it should speed up other things than graphics as well.

- epsylon 13y agoIt's quite good, but still far from a discrete GPU.
