The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
The 12 E-cores provide massive throughput for rendering and compilation.
Handles multi-threaded creator workloads well, though modern CPUs with higher IPC and efficiency outpace it.
Gaming
Delivers top-tier framerates, competing directly with flagship CPUs.
Capable for 1080p and 1440p gaming with a strong GPU, but newer mainstream CPUs offer higher frame rates and better responsiveness.
Virtualization
Excellent for running multiple VMs and containers.
Excellent for running multiple VMs thanks to 8 cores, 16 threads, and quad-channel memory.
Efficiency
Power draw can spike significantly under full multi-core load.
High 140 W TDP results in higher power draw and heat versus newer generations.
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; relies on CPU-based vector instructions and AVX2.
- Suitable for lightweight inference and batch tasks; deep learning training is better served by 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.
- Quad-channel memory and high core count do not significantly improve gaming framerates over dual-channel mainstream parts.
- Turbo Boost Max 3.0 provides slightly better single-core performance on lightly-threaded titles.
- PCIe 3.0 lanes are sufficient for current GPUs, but platform age limits upgrade options.
