Front view of Intel Core i7 2600

Reasons to consider the
Intel Core i7 2600

Report a correction
Much higher clock speed 3.4 GHz vs 2.3 GHz Around 50% higher clock speed
Much more l3 cache 8 MB vs 0.5 MB 16x more l3 cache; more data can be stored in the l3 cache for quick access later
Much newer manufacturing process 32 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much better PassMark score 8,219 vs 1,098 Around 7.5x better PassMark score
Much better PassMark (Single core) score 1,921 vs 669 More than 2.8x better PassMark (Single core) score
Much better geekbench 2 (32-bit) score 11,071 vs 1,585 Around 7x better geekbench 2 (32-bit) score
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 8 vs 2 6 more threads
Much better overclocked clock speed (Air) 3.93 GHz vs 3.01 GHz More than 30% better overclocked clock speed (Air)
Much more l3 cache per core 2 MB/core vs 0.25 MB/core 8x more l3 cache per core
Much better overclocked clock speed (Water) 3.92 GHz vs 3.27 GHz Around 20% better overclocked clock speed (Water)
Newer Jan, 2011 vs Apr, 2008 Release date over 2 years later
