CPU Comparison
Intel Core i7-3960X Processor vs Core i7-4960X
A side-by-side comparison of specs, performance and value. The Intel Core i7-3960X is a six-core Extreme Edition processor for LGA2011, launched in late 2011 as the flagship of Intel's Sandy Bridge-E HEDT platform.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Six cores and Hyper-Threading help in older workloads, though newer CPUs complete multi-threaded tasks much faster and more efficiently.
Still a very capable chip for heavy multi-threaded workloads.
Gaming
Playable in many titles at 1080p with a strong GPU, but frame rates and 1% lows fall behind modern processors.
High clocks keep it decent for gaming, though 6 cores are showing age.
Virtualization
Quad-channel memory and 12 threads suit lab or VM setups on legacy hardware.
Excellent for home labs with 12 threads and 40 PCIe lanes.
Efficiency
High power draw relative to performance makes it inefficient by today's standards.
130W TDP with 22nm is very power-hungry by modern standards.
Specialized Performance
AI / ML
- No dedicated AI acceleration hardware
- Can run basic CPU-based inference, but impractical for modern ML workloads
- Good for multi-GPU AI setups due to 40 lanes
- No native AI hardware
Content Creation
Gaming
- Requires strong GPU to mitigate CPU bottlenecks in newer titles
- High-refresh gaming is generally unrealistic
- DDR3 quad-channel does not compensate for low per-core performance
- High single-core speed for the era
- Needs discrete GPU
- Can bottleneck modern GPUs at 1080p
