Intel® Core™ Ultra 7 Processor 265KF BOX

The monster of the future has arrived! A detailed review of the revolutionary Intel® Core™ Ultra 7 265KF processor
Intel is completely changing the game with the new generation (Series 2) featuring Arrow Lake architecture. If you're looking for a processor that combines pure gaming power with integrated artificial intelligence to speed up your work in editing and content creation, the Core™ Ultra 7 265KF is the natural evolution of your device.
Why is this processor different?
1. Advanced hybrid architecture (20 real cores!): Intel has abandoned traditional Hyper-Threading here and focused on real cores:
8 Performance cores (P-cores): for heavy tasks and gaming, with a frequency reaching up to 5.4 GHz.
12 Efficiency Cores (E-cores): for background tasks and multitasking, with a frequency of up to 4.6 GHz.
The total: 20 cores and 20 threads working in perfect harmony thanks to the Intel® Thread Director.
2. The Era of Artificial Intelligence (AI Boost): For the first time on desktop, the processor features an integrated NPU (Neural Processing Unit) with a power of 13 TOPS.
What does it mean? It means incredible acceleration for any program that uses artificial intelligence (like the isolation features in Zoom, Photoshop filters, and editing software) without putting pressure on the graphics card or the main processor.
3. Better thermal performance and energy efficiency: Thanks to the manufacturing precision of TSMC N3B, the processor delivers very high performance with smart power consumption (Base Power 125W and up to 250W under maximum load).
4. Ready for the Future (Connectivity):
Support for DDR5 RAM with speeds reaching up to 6400 MT/s.
Support for PCIe 5.0 for upcoming graphics cards and NVMe storage units.
Thunderbolt™ 4 support for lightning-fast data transfer.
