![]() Like the 9400M, the 320M has a full fledged chipset to go along with it. ![]() The 320M has 48 cores up from the 16 that were in last year's GeForce 9400M. It's an upgrade from the 2.26GHz model that shipped with last year's model, but no where near as fast as the Core i5 you get with the 15-inch MBP.Īpple justifies the mild CPU upgrade by including a much more potent GPU: the GeForce 320M. The new 13-inch MacBook Pro starts with a 2.4GHz Core 2 Duo processor based on the three year old Penryn core. ![]() Rather than sacrifice the GPU, Apple sacrificed CPU speed. There's not enough motherboard real estate to include an Arrandale Core i3/i5 CPU plus an NVIDIA discrete GPU like Apple does in the new 15 and 17-inch models. The unwillingness to ship a Mac without real GPGPU support leads us to the current problem with the 13-inch MacBook Pro. In preparation for what I'm not really sure, but something is coming. From the looks of it, Apple is trying to broaden its install base of OpenCL compliant machines. These are all G9x based GPUs with full support for OpenCL. For the past 1.5 years every single Mac has shipped with some form of NVIDIA graphics, standard, regardless of price.
