Intel Core i7-965

Differences

Reasons to consider the AMD A4-4000

CPU is newer: launch date 4 year(s) 6 month(s) later
A newer manufacturing process allows for a more powerful, yet cooler running processor: 32 nm vs 45 nm
2x more L2 cache, more data can be stored in the L2 cache for quick access later
2x lower typical power consumption: 65 Watt vs 130 Watt

Launch date	June 2013 vs November 2008
Manufacturing process technology	32 nm vs 45 nm
L2 cache	1024 KB (per core) vs 256 KB (per core)
Thermal Design Power (TDP)	65 Watt vs 130 Watt

Reasons to consider the Intel Core i7-965

Processor is unlocked, an unlocked multiplier allows for easier overclocking
2 more cores, run more applications at once: 4 vs 2
Around 15% higher clock speed: 3.46 GHz vs 3 GHz
Around 30% better performance in PassMark - Single thread mark: 1475 vs 1137
3x better performance in PassMark - CPU mark: 3424 vs 1152
Around 61% better performance in Geekbench 4 - Single Core: 578 vs 359
4.3x better performance in Geekbench 4 - Multi-Core: 2233 vs 525
