CPU Comparison
Intel Core i9-9980XE vs Intel Xeon 654 Processor
A side-by-side comparison of specs, performance and value. The Intel Core i9-9980XE is an 18-core, 36-thread high-end desktop processor built on the Skylake-X architecture and manufactured on Intel’s 14nm++ process. Designed for the LGA2066 platform, it offers quad-channel DDR4-2666 memory support, 44 PCIe 3.0 lanes, and aggressive turbo frequencies up to 4.5 GHz via Turbo Boost Max 3.0, making it aimed at content creators, workstation users, and enthusiasts who need massive multi-threaded performance and ample I/O. Intel markets it as a 9th-gen Core X-Series part, but under the hood it is a Skylake-X refresh rather than a new microarchitecture, with the same 18-core die as the earlier i9-7980XE but higher clocks and solder thermal interface material for improved thermals. Launched in Q4 2018 and now discontinued, it was Intel’s flagship HEDT CPU until the Cascade Lake-X i9-10980XE arrived in late 2019.

AI / ML
- No dedicated AI acceleration like Intel DL Boost or AVX-512 BF16.
- AVX-512 is present, but focused on traditional HPC/rendering workloads.
- Only suitable for CPU-based AI inference or small models; GPU acceleration is preferred for serious AI work.
- AMX with FP16/BF16/INT8 accelerates many AI workloads natively on CPU.
- Best for inference and mid-size training where GPU memory is a bottleneck.
- For large-scale training, multi-GPU or dedicated AI accelerators are still preferred.
Content Creation
Gaming
- Strong single-threaded and light-threaded performance thanks to high turbo clocks.
- Often outperforms 1st- and 2nd-gen Threadripper in games at similar core counts.
- Modern gaming-focused CPUs (e.g., Intel 13th/14th gen, AMD Ryzen 7000) are usually faster and more efficient.
- High single-thread clocks and good IPC deliver solid gaming performance at high refresh rates.
- Platform is optimized for workstations, not gaming; cost and I/O are overkill for gamers.
- Modern high-end desktop CPUs often provide better gaming value and efficiency.

More efficient mainstream desktop CPU with strong creator performance, but without workstation I/O or memory capacity.
Our Verdict on Each
A very powerful HEDT CPU with strong multi-threaded performance and excellent I/O, but high power consumption and a steep price make it hard to recommend over AMD’s Threadripper alternatives unless you specifically need Intel’s platform features.
Best for: Used or heavily discounted upgrade for an existing X299 workstation where you need maximum cores and PCIe lanes without replacing the motherboard.
Read the full reviewA strong entry-level Granite Rapids-WS workstation CPU with excellent memory and I/O bandwidth, but it faces stiff competition from higher-core AMD Threadripper and EPYC parts in heavily multi-threaded workloads.
Best for: Building a new single-socket workstation for rendering, simulation, or AI where you need eight-channel memory and 128 PCIe 5.0 lanes and want Intel’s platform.
