A lower-cost configuration with integrated Intel Iris Pro graphics is also available. Packing an AMD Radeon R9 M370X GPU, the newest 15-inch MacBook Pro is designed to deliver 80 times the graphics performance as last year's model. The MacBook Pro took 4 minutes and 14 seconds to match 20,000 names to their addresses, outpacing our 5:05 average while nearly tying the ZBook 15u (4:15) and falling behind the XPS (4:09) and the WS60 (3:53). The latest MacBook also topped the XPS 15's 512GB SSD (154.2 MBps), the ZBook's 256GB SSD (175.5 MBps) and even the WS60's dual 128GB SSDs, which finished the test at an impressive 365.2 MBps. The new MacBook Pro's flash performance crushes the 282.7 MBps we churned out of last year's model, though that unit had a smaller 256GB SSD. Having this kind of flash storage will make finding files amidst huge libraries a snap. Our review unit's 512GB SSD transferred 4.97GB of mixed media in a ridiculously quick 8 seconds, for a colossal transfer rate of 636 MB per second. Apple promises exponentially better flash performance with the refreshed MacBook Pro's next-generation PCIe-based flash storage, and the computer delivers.
