The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
8 physical cores provide ample power for compiling code, rendering, and heavy multitasking scenarios.
Six cores and Hyper-Threading help in older workloads, though newer CPUs complete multi-threaded tasks much faster and more efficiently.
Gaming
The high boost clock ensures strong gaming performance, particularly in competitive titles where single-core speed is paramount.
Playable in many titles at 1080p with a strong GPU, but frame rates and 1% lows fall behind modern processors.
Virtualization
Sufficient thread count and ECC support make it a reliable choice for light to moderate virtualization workloads.
Quad-channel memory and 12 threads suit lab or VM setups on legacy hardware.
Efficiency
While the 10nm process is mature, the 253W PL2 limit indicates high power consumption during turbo bursts.
High power draw relative to performance makes it inefficient by today's standards.
Specialized Performance
AI / ML
- No dedicated NPU hardware on this specific model
- Relies on CPU-based AVX-512 and VNNI for inference
- Best paired with a dedicated GPU for AI workloads
- No dedicated AI acceleration hardware
- Can run basic CPU-based inference, but impractical for modern ML workloads
Content Creation
Gaming
- High 5.5 GHz boost clock favors FPS in e-sports
- PCIe Gen 5 support ready for future GPUs
- 8 cores enough for modern gaming titles
- Requires strong GPU to mitigate CPU bottlenecks in newer titles
- High-refresh gaming is generally unrealistic
- DDR3 quad-channel does not compensate for low per-core performance
