Quick Links
18 Cores, 18 Threads – 6 P-Cores + 12 E-Cores, Up to 5.3 GHz
The core layout is 6 Performance cores and 12 Efficiency cores for a total of 18 cores and 18 threads. Like the rest of the Arrow Lake lineup, there’s no Hyper-Threading — each core runs a single thread.
| Core Type | Base | Max Turbo |
|---|---|---|
| P-core | 4.2 GHz | 5.3 GHz |
| E-core | 3.3 GHz | 4.6 GHz |
Interesting to note: the P-core base clock here (4.2 GHz) is actually higher than the Ultra 7 270K Plus’s 3.7 GHz base, though the 270K Plus pulls ahead on turbo with 5.5 GHz via Turbo Boost Max 3.0. The 250K Plus uses standard Turbo Boost 2.0 only.
30MB Smart Cache + 30MB L2, TSMC N3B, 125W/159W
Cache totals 30MB Intel Smart Cache (L3) and 30MB L2. The chip is fabbed on TSMC N3B and draws 125W at base (PBP) with a max turbo power of 159W (MTP) — considerably less thermal headroom needed compared to the 270K Plus’s 250W ceiling.
30 TOPS AI – Intel AI Boost NPU (13 TOPS), 4 Xe-Core GPU (8 TOPS)
Combined AI throughput reaches 30 TOPS (Int8) across all three engines:
- NPU: 13 TOPS (Intel AI Boost, sparsity, Windows Studio Effects)
- GPU: 8 TOPS (4 Xe-cores, up to 1.9 GHz)
- CPU: ~9 TOPS (Intel DL Boost)
Framework support: OpenVINO, WindowsML, DirectML, ONNX RT, WebNN (CPU/NPU) and WebGPU (GPU).
Intel Graphics – 4 Xe-Cores, 1.9 GHz, Quick Sync AV1, 4 Displays
The integrated GPU has 4 Xe-cores running from 300 MHz base to 1.9 GHz max. Display connectivity supports eDP 1.4b, DP 2.1 UHBR20, and HDMI 2.1 FRL — up to 4 simultaneous displays.
Max resolutions:
- HDMI: 4096 × 2304 @ 60Hz (TMDS) / 7680 × 4320 @ 60Hz (FRL)
- DisplayPort: 7680 × 4320 @ 60Hz
Quick Sync Video covers H.264, H.265, and AV1 hardware encode/decode. DirectX 12, OpenGL 4.5, OpenCL 3, and HDCP 2.3 are supported.
