CPU Comparison
Intel Core i7-6850K vs Core i7-3930K
A side-by-side comparison of specs, performance and value. The Intel Core i7-6850K is a high-end desktop processor that occupies the middle tier of the Broadwell-E lineup. Engineered for demanding enthusiasts and professional creators, it features six cores and twelve threads, providing substantial parallel processing power. It operates at a base clock of 3.6 GHz and can boost up to 4.0 GHz using Intel Turbo Boost Max 3.0, ensuring snappy single-threaded performance when needed. Unlike the entry-level 6800K, the 6850K offers a full 40 PCIe 3.0 lanes, unlocking maximum expansion potential for quad-GPU setups or massive NVMe storage arrays. It utilizes the LGA 2011-v3 socket and supports quad-channel DDR4 memory, delivering up to 76.8 GB/s of bandwidth. With a 140-watt TDP, it is a power-hungry chip designed for robust cooling. Lacking integrated graphics, it targets users who rely on discrete GPUs, excelling in complex 3D rendering, heavy video editing, and intensive virtualization environments where PCIe lanes and memory bandwidth are critical bottlenecks.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
6 cores handle heavy rendering well, but lack modern IPC.
6 cores and 12 threads hold up well for content creation.
Gaming
Good for 60fps gaming, but single-core speed limits high-refresh performance.
Still decent for modern gaming, though single-core is slower than new CPUs.
Virtualization
40 PCIe lanes and 12 threads make it excellent for VMs.
Excellent for VMs with 12 threads and quad-channel memory.
Efficiency
140W TDP is power-hungry by modern standards.
130W TDP and 32nm process mean it runs hot and uses power.
