MacBook Pro - Review - part 5 - General Performance

As for the processor, the changes are less noticeable. While the other models featured Intel T series processors, now they are Intel P series. That is due to the Penryn series update. The TDP (Thermal design power) of the P series is only 25 watts (compared to the 35 Watts from the T series). Consequently, the system should be faster and consume less energy. There’s also the option of a Core 2 Duo T9600, which is faster, but heavier in terms of energy consumption.

Thanks to the GDDR3 and the graphic performances on the GeForce 9600M, it’s possible to play heavier games with medium details and lighter games with high details with no problems. The 320 GB HD has a 5400 rpm speed, being more silent compared to the 7200 rpm ones. During benchmarks, the HD has reached a maximum writing speed of 63 MB/sec.
