Processor comparison
Core i7-6700K vs Core i7-7700K
6th gen vs 7th gen Intel Core desktop processors, compared spec by spec using Intel's official data.
The short answer
On paper, the Core i7-7700K is the stronger processor, ahead of the Core i7-6700K in 2 of the specs we compare (the Core i7-6700K leads in 0).
- The Core i7-7700K is 1 generation newer (7th gen, launched Q1'17) than the Core i7-6700K (6th gen, Q3'15). Both are built on the same basic core design, so the differences come mainly from core counts, clock speeds and cache.
- Both have 4 cores and 8 threads.
- The Core i7-7700K reaches 4.50 GHz with turbo, 7% higher than the Core i7-6700K's 4.20 GHz. Higher clocks help games and everyday apps that lean on a few fast cores.
This verdict is generated from official specifications only. We haven't benchmarked these processors, so it doesn't measure real-world speed in games or apps; check independent benchmarks for your specific use.
