CPU Comparison
Intel Core i7-5960X vs Intel Core i7-7820X
A side-by-side comparison of specs, performance and value. The Intel Core i7-5960X Processor Extreme Edition is an 8-core, 16-thread enthusiast desktop processor built on the 22 nm Haswell-E architecture, featuring quad-channel DDR4 memory support, 40 PCIe 3.0 lanes, and a 140 W TDP for the X99 (LGA2011-v3) platform.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong multi-threaded throughput in workloads that scale across cores—such as rendering and compression—despite lower per-clock performance versus newer designs.
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
With a modern discrete GPU, the i7-5960X remains playable at high refresh rates, though newer CPUs offer higher 1% lows and frame times.
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
The combination of eight cores, 16 threads, and VT-x/VT-d makes it well-suited for running multiple VMs.
PCIe and memory bandwidth are helpful for multiple VMs, but core count is moderate for modern heavy virtualization needs.
Efficiency
The 140 W TDP at 3.0 GHz base reflects 22 nm efficiency limits; newer chips deliver similar performance with far lower power.
High 140 W TDP and 14 nm process lead to greater power consumption versus newer 7 nm and smaller nodes.
Specialized Performance
AI / ML
- No dedicated AI acceleration (e.g., DL/ML matrix extensions).
- Suitable for light CPU-based inference, but far slower than modern NPUs/accelerators.
- 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
- Requires a discrete graphics card; no integrated graphics.
- PCIe 3.0 x16 bandwidth is ample for current GPUs.
- Single-thread performance limits headroom in CPU-bound titles.
- 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 milestone eight-core HEDT processor with strong multi-threaded performance and expansion options, but high power draw and an aging platform limit its appeal in new builds.
Best for: Upgrading or maintaining an existing X99 system at very low cost; secondary workstation rigs.
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.
