Report a correction
Higher clock speed 3.2 GHz vs 2.8 GHz Around 15% higher clock speed
Much higher GPU clock speed 650 MHz vs 350 MHz More than 85% higher GPU clock speed
More l3 cache 6 MB vs 2 MB 3x more l3 cache; more data can be stored in the l3 cache for quick access later
Significantly better turbo clock speed 1,100 MHz vs 950 MHz More than 15% better turbo clock speed
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
More cores 4 vs 2 Twice as many cores; run more applications at once
More l3 cache per core 1.5 MB/core vs 1 MB/core 50% more l3 cache per core
More threads 4 vs 2 Twice as many threads
