The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
The 12 E-cores provide massive throughput for rendering and compilation.
Very strong in multi-threaded creator applications; competitive with early 2nd-gen Threadripper and superior to mainstream 8-core parts of its era.
Gaming
Delivers top-tier framerates, competing directly with flagship CPUs.
Smooth high-refresh gameplay at 1440p in most titles, but newer mainstream CPUs often deliver better minimums and efficiency.
Virtualization
Excellent for running multiple VMs and containers.
Excellent for running multiple VMs due to high core count, quad-channel memory, and VT-d/VT-x support.
Efficiency
Power draw can spike significantly under full multi-core load.
High power draw and heat output under load; significantly less efficient than modern 12-core and 16-core CPUs from both Intel and AMD.
Specialized Performance
AI / ML
- CPU-based AI inference is strong due to 28 threads.
- No dedicated NPU like mobile platforms.
- Integrated graphics can assist in basic VPU workloads.
- No dedicated AI or matrix hardware beyond AVX-512.
- Can handle CPU-based inference for small models, but is outclassed by modern NPUs and GPUs for serious AI workloads.
Content Creation
Gaming
- High single-core boost ensures max FPS in CPU-bound titles.
- Large cache size benefits modern AAA games.
- Requires a high-end GPU to avoid bottlenecks at 1080p.
- High single-core boost (4.4/4.5 GHz) keeps frame rates high in CPU-heavy titles.
- Quad-channel memory can help in some CPU-limited scenarios.
- Modern 6–8 core mainstream CPUs often match or beat it in gaming while using less power.
- Best paired with a high-end GPU for balanced system; GPU bottlenecks are more likely at 4K.

Our Verdict on Each
An exceptional desktop CPU that blurs the line between i7 and i9, offering tremendous multi-core value and top-tier gaming clocks.
Best for: Users wanting a single system for high-refresh gaming and heavy productivity.
Read the full reviewA capable HEDT CPU with excellent multi-threaded performance and expansive I/O, but high power consumption and an aging platform make it primarily interesting for used workstation builds rather than new systems.
Best for: Used workstation or HEDT build where X299, quad-channel memory, and many PCIe lanes are requirements, and a modern platform upgrade is not feasible.
