11th Gen Intel Core i5-11600K Review
The 11th Gen Intel Core i5-11600K is a 6-core, 12-thread unlocked Rocket Lake desktop processor, running a 3.9 GHz base clock that boosts to 4.9 GHz within a 125 Watt TDP on the LGA 1200 socket.
As Intel's mainstream unlocked Rocket Lake option, this chip brought genuine overclocking flexibility to a 6-core desktop tier, appealing to gaming-focused builders who don't need the full 8-core i7 or i9 tier.
Intel UHD Graphics Xe 750 (32 EU)
A modest integrated GPU appropriate as a fallback; this chip is typically paired with a discrete GPU for actual gaming.
How Is the Core i5-11600K in Terms of Performance
The unlocked multiplier and strong 4.9 GHz boost clock make this chip a genuine value pick for gaming-focused desktop builds, with Rocket Lake's architectural IPC gains giving it competitive per-core performance against the pricier i7 and i9 tiers.
Benchmarks
Cinebench R23 multi-core scores of 11,367 and single-core scores of 1,563 reflect strong 6-core Rocket Lake performance. Geekbench 5 single-core scores of 1,723 confirm genuinely competitive single-threaded responsiveness for gaming, close to the pricier i7-11700K's 1,782 score.
