The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
The 12 E-cores provide massive throughput for rendering and compilation.
Strong multi-threaded performance for creator workloads; competitive with or better than many mainstream 8–10 core CPUs at the time, though newer designs are faster per clock.
Gaming
Delivers top-tier framerates, competing directly with flagship CPUs.
Capable of high-refresh-rate gaming at 1440p and above, but modern gaming-focused CPUs often deliver better minimums and efficiency.
Virtualization
Excellent for running multiple VMs and containers.
Excellent for running multiple VMs thanks to 10 cores, 20 threads, and quad-channel memory, especially when paired with VT-x and VT-d support.
Efficiency
Power draw can spike significantly under full multi-core load.
High power consumption and heat output compared to modern 10nm/7nm parts; requires robust cooling and a strong PSU.
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 acceleration hardware like NPU or AI instructions beyond AVX-512.
- Suitable for CPU-based inference and small model workloads, but not competitive with modern AI-focused CPUs or GPUs.
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.
- Strong single-core clocks up to 4.3–4.5 GHz enable high FPS in CPU-heavy titles.
- Most games don’t scale beyond 6–8 cores, so newer 8-core CPUs often match or beat it in gaming while using less power.
- Best suited for GPU-bound scenarios at 1440p/4K where the CPU is less of a bottleneck.

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 once-flagship HEDT CPU that still delivers strong multi-threaded performance and I/O capability, but its 14nm process, high power draw, and discontinued platform make it mainly interesting for used builds or legacy systems.
Best for: Used workstation or creator build on X299 where multi-threaded performance and I/O matter more than efficiency or platform longevity.
