Reasons to consider the
Intel x5-Z8330

Report a correction
Much newer manufacturing process 14 nm vs 45 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
Newer Jan, 2016 vs Jan, 2008 Release date over 8 years later
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 4 vs 2 Twice as many threads

Much better geekbench 3 AES single core score 98,000 MB/s vs 297.1 MB/s More than 329.8x better geekbench 3 AES single core score
Significantly higher clock speed 2.4 GHz vs 1.44 GHz More than 65% higher clock speed
Significantly more l2 cache 3 MB vs 2 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Much more l2 cache per core 1.5 MB/core vs 0.5 MB/core 3x more l2 cache per core
Significantly better overclocked clock speed (Air) 2.53 GHz vs 1.68 GHz More than 50% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 3.2 GHz vs 1.44 GHz Around 2.2x better overclocked clock speed (Water)
