Core Ultra 7 265K Workstation

This new desktop PC pairs a 20-core Intel Core Ultra 7 265K processor with 128GB of DDR5 memory and a 240mm liquid cooler. A 1TB NVMe SSD and a 10TB hard drive provide fast boot and deep storage capacity. The system ships with Windows 11 Pro installed and uses integrated graphics for video output via HDMI and DisplayPort.

For AI-ready productivity, not discrete gaming

The configuration suits professionals who want a quiet, liquid-cooled platform for multi-threaded workloads, large datasets or AI-ready tasks with high memory bandwidth. Buyers who need a dedicated graphics card for 3D rendering, hardware video encoding or GPU-accelerated compute should look elsewhere. The integrated GPU handles standard display output and light media duties only.

128GB DDR5 across four slots

The motherboard supports a maximum of 192GB, leaving headroom for future expansion if workloads grow. All four slots are populated in this build, so any upgrade requires replacing existing modules. Verify your application's memory scaling before committing to the current capacity.
