CPU Comparison
Intel Core i7-6950X vs Intel Core i7-7820X
A side-by-side comparison of specs, performance and value. The Intel Core i7-6950X Extreme Edition is a 10-core, 20-thread high-end desktop processor built on the 14 nm Broadwell-E architecture, featuring quad-channel DDR4 memory, 40 PCIe 3.0 lanes, and an unlocked multiplier for enthusiasts.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Excellent multi-threaded performance for its era; still capable in many parallel workloads but less efficient than modern CPUs.
Strong multi-threaded throughput in CINEBENCH, HandBrake, and similar workloads at launch; still competent for many content creation tasks compared to modern mainstream parts.
Gaming
Playable in modern titles when paired with a strong GPU, but newer mainstream CPUs deliver higher frame rates and better responsiveness.
Delivers high frame rates in 2017-era titles and remains adequate for modern gaming, but newer gaming-focused CPUs with higher clocks and improved IPC pull ahead.
Virtualization
High core/thread count and VT-x/VT-d support make it very capable for running multiple VMs.
PCIe and memory bandwidth are helpful for multiple VMs, but core count is moderate for modern heavy virtualization needs.
Efficiency
High power draw under load compared to current-generation processors; 14 nm and 140W TDP limit efficiency.
High 140 W TDP and 14 nm process lead to greater power consumption versus newer 7 nm and smaller nodes.
Specialized Performance
AI / ML
- Lacks dedicated AI accelerators; AI workloads rely on CPU and any discrete GPU.
- No dedicated AI acceleration hardware
- AVX-512 can help certain CPU-bound inference tasks
- Most modern AI workloads are better served by GPUs
Content Creation
Gaming
- Adequate for high-refresh gaming with a strong GPU in many titles
- Gains more from GPU upgrades than CPU upgrades in typical game workloads
- Newer gaming-focused CPUs offer better frame pacing and lower latency
- Capable of high-refresh gaming with a strong GPU
- Single-core boost reaches up to 4.5 GHz on favored cores
- Modern CPUs offer better gaming efficiency and higher IPC

Our Verdict on Each
A multi-threaded powerhouse for its time, the i7-6950X brought 10 cores to desktop HEDT but commanded a steep price and has since been eclipsed in performance and efficiency by newer platforms.
Best for: Used-market X99 upgrade for creators on a tight budget
Read the full reviewA competent eight-core HEDT chip with strong multi-threaded performance and platform expansion, though high power draw and limited PCIe lanes compared to higher-tier X299 CPUs make it a niche choice today.
Best for: Used-market upgrade for an existing X299 build with quad-channel DDR4 and a need for more cores than mainstream.
