The new Core i7-8700K will be a bigger beast than its predecessor, coming in as a 6C/12T processor compared to the 7700K which is a 4C/8T chip. The new Coffee Lake-based Core i7-8700K will compete against AMD's Ryzen 5 1600X which is also a 6C/12T, but offer some monster performance over the 7700K which still reigns supreme for gamers.

Looking at the single-threaded performance, the 8700K is around 11% faster than the 7700K, but in multi-threaded performance the new Coffee Lake-based 8700K and its 6C/12T of CPU grunt pushes it to be 51% faster.

HotHardware posted some comparison scores between the aggregated Core i7-7700K and the new 8700K:

  • Processor Arithmetic: 217.98 GOPS (versus 149.99 GOPS)-45 percent increase
  • Processor Multi-Media: 658.57 Mpix/s (versus 447.76 Mpix/s)-47 percent increase
  • Processor Cryptography: 10.47 GB/s (versus 9.34 GB/s)-12 percent increase
  • Scientific Analysis (Single Precision): 61.41 GFLOPS (versus 48.51 GFLOPS)-26 percent increase
  • Scientific Analysis (Double Precision): 32.11 GFLOPS (versus 24.40 GFLOPS)-32 percent increase
