Intel Core i9-10980XE vs Intel Core i9-9990XE
A side-by-side comparison of specs, performance and value. The Intel Core i9-10980XE is an 18-core, 36-thread high-end desktop processor built on the Cascade Lake-X architecture for enthusiasts and creators who need lots of PCIe lanes and quad-channel memory bandwidth on the LGA2066 platform.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Strong multi-threaded performance in Premiere, Blender, and similar creator applications, especially when heavily threaded.
Very strong multi-threaded performance for Adobe apps, rendering, and simulation workloads, competitive with or slightly ahead of the 18-core i9-9980XE in some tests.
Gaming
Capable of high-refresh-rate gaming at 1440p and 4K, but modern gaming-optimized CPUs often deliver better minimums and efficiency.
Capable of high-refresh-rate gaming thanks to strong single-core clocks, but modern gaming-focused CPUs often deliver better minimums and efficiency at far lower cost.
Virtualization
Excellent for running multiple VMs or containers, thanks to 18 cores and ample memory bandwidth.
Good for running several VMs thanks to 14 cores and quad-channel memory, but high power draw and lack of warranty are concerns for 24/7 use.
Efficiency
Power-hungry even by HEDT standards; draws significantly more power than newer mainstream and HEDT designs for similar work.
Extremely low efficiency; 255 W TDP at base frequency and much higher real power draw under all-core boost makes it one of the most power-hungry HEDT CPUs of its era.
Specialized Performance
AI / ML
- AVX-512 and DL Boost help with CPU-based inference and some AI workloads
- No dedicated AI accelerator; far slower than modern NPUs or GPUs for large models
- No dedicated AI or matrix hardware; AI workloads rely on AVX-512 and CPU-based inference.
- Suitable for small-scale CPU inference and prototyping, but not competitive with modern NPUs or GPUs.
Content Creation
Gaming
- High single-core boost up to 4.8 GHz helps in CPU-heavy titles
- PCIe 3.0 x16 is sufficient for current GPUs, but lacks PCIe 4.0/5.0 benefits
- Modern gaming CPUs often outperform it in latency-sensitive titles and 1% lows
- High clock speeds give strong single-threaded performance for high-refresh-rate gaming.
- 14 cores are underutilized in most games, which favor fewer faster cores.
- Modern gaming CPUs (e.g., 13th/14th Gen Core i9, Ryzen 7000) often deliver better gaming performance per watt and per dollar.

Our Verdict on Each
Still a potent workstation and creator CPU thanks to its core count and expansion, but its 14nm process and high power draw make it hard to recommend over modern mainstream or HEDT alternatives unless bought cheap on the used market.
Best for: Used or heavily discounted workstation/creator build where you need many PCIe lanes and cores and already have an X299 motherboard.
Read the full reviewAn extraordinarily fast but impractical CPU: stellar clocks and multi-threaded performance for its era, but extreme power draw, no warranty, and near-zero availability make it a collector’s item rather than a practical purchase.
Best for: Boutique workstation integrator with existing X299 inventory and a specific need for the highest possible clocks on 14 cores, regardless of cost or warranty.
