Intel Core i5-11600K CPU Review 2

Hot on the heels of our recent Core i9-11900K review comes its little brother, the Core i5-11600K. It features the same new architecture and improvements, as well as connectivity support, but in a more cost-effective 6-core package. We also find optional platform support for USB 3.2 gen2x2 20gbps USB, Intel Thunderbolt 4, USB4, and WiFi 6E support for maximum speed connectivity to, well, everything. New overclocking features such as a new memory controller with real-time memory overclocking from your desktop, memory overclocking support on H570 and B560 chipsets, AVX enable/disable options, and even AVX2 and AVX-512 guard-band overrides, you can tune like never before.

We want to thank Intel for sending us over the new Core i5-11600K to test out!

Intel’s take on the Core i5-11600K:

The 11th Gen Intel® Core™ desktop processor family puts you in control of your computing experience. It features an innovative new architecture for reimagined performance, immersive display and graphics for incredible visuals, and a range of options and technologies for enhanced tuning. When these advances come together, you have everything you need for fast-paced professional work, elite gaming, inspired creativity, and extreme tuning. The 11th Gen Intel® Core™ desktop processor family gives you the power to perform, compete, excel, and power your greatest contributions.

Performance: Reimagined Performance
11th Gen Intel Core desktop processors are intelligently engineered to push the boundaries of performance. The new processor core architecture transforms hardware and software efficiency and takes advantage of Intel Deep Learning Boost to accelerate AI performance. Key platform improvements include memory support up to DDR4-3200, up to 20 CPU PCIe 4.0 lanes, integrated USB 3.2 Gen 2×2 (20G), and Intel Optane Memory H20 with SSD support. Together, these technologies bring the power and the intelligence you need to supercharge productivity, stay in the creative flow, and game at the highest level.

Creativity: Immersive Display & Graphics
Experience rich, stunning, seamless visuals with high-performance graphics on 11th Gen Intel Core desktop processors. Enhanced Intel UHD Graphics featuring Intel Xe graphics architecture offers powerful media and graphics capabilities to bring your virtual world to life. Key platform advances enable complete immersion—with integrated HDMI 2.0 and HBR3 for up to three simultaneous 4K HDR displays at 60Hz; 12bit HEVC/VP9 decode and E2E compression for efficient, enhanced quality of media; and 10bit AV1 Codec decode support that provides true fixed function-based decoding for fast, energy-efficient performance with video calling and screen share. Just sit down and dive in—to uncompromised in-game performance while streaming and recording, seamless multi-tasking across multiple screens, or fast creating and editing for even the most demanding tasks.

Tuning: Enhanced Tuning & Control
11th Gen Intel Core desktop processors offer you the flexibility and control to power your greatest contributions. Unlocked 11th Gen Intel® Core desktop processors enable you to overclock confidently with enhanced features3 like Intel® Performance Maximizer, Intel Extreme Tuning Utility (Intel® XTU), Solder Thermal Interface Material (STIM), and improved overclocking customizations. Now you can push your CPU to the limits, open new performance horizons, or re-imagine streaming and recording. 11th gen processors also simplify connectivity through Intel® Thunderbolt 4 (discrete USB4 compliant), enhance expandability through high-speed PCIe lanes and USB 3.2 Gen 2×2 (20G), and advance wireless connectivity through discrete Wi-Fi 6E. Take control and push ahead with the processors that maximize whatever matters most to you.
