Report a correction
Much more l2 cache 4 MB vs 2 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly higher clock speed 3.46 GHz vs 2.33 GHz Around 50% higher clock speed
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Much more l2 cache per core 2 MB/core vs 1 MB/core 2x more l2 cache per core
Much better overclocked clock speed (Air) 4.39 GHz vs 2.81 GHz More than 55% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 4.61 GHz vs 2.33 GHz Around 2x better overclocked clock speed (Water)
More threads 4 vs 2 Twice as many threads
