the latest MacBook Pro isn't a landmark revamp of the line, by any means. All told, the understated improvements match the understated announcement. The 13-inch version of the machine simply got a slightly faster processor than the early-2011 13-inch MacBook Pro had, jumping from a 2.3GHz Intel Core i5 to a 2.4GHz one. (Both are dual-core chips.)
The $1,799 15-inch base model, which we reviewed here, gets a slightly more impressive bump. This MacBook goes from a 2GHz quad-core Intel Core i7 processor to a 2.2GHz quad-core Core i7, and it gets an excellent improvement in graphics, from a single AMD Radeon HD 6490M graphics chip to a switchable-graphics arrangement. The late-2011 model is powered by both the Intel HD Graphics 3000 circuitry that's built into the processor chip and separate AMD Radeon HD 6750M graphics, backed by 512MB of onboard video memory.
