20-Core Ultra 7 Workstation

This desktop pairs a 20-core Intel Core Ultra 7 265K processor with 192GB of DDR5 memory and an Nvidia GeForce RTX 5090 graphics card holding 32GB of video memory. It targets professionals who need a single machine for rendering, modelling and AI learning workloads alongside high-end gaming. The system ships with Windows 11 Pro installed and uses a 240mm liquid cooler on the CPU.

Sustained Load Behaviour

The 240mm liquid cooler is designed to keep the 20-core processor at stable clocks during long rendering or training sessions rather than only during short bursts. A 1000W 80 Plus Gold power supply with Japanese main capacitors delivers continuous power to the GPU and CPU without throttling. The Corsair 4000D chassis moves air through a 140mm fan to maintain internal temperatures over extended periods.

Interface Practical Limits

The Z890 motherboard provides one Thunderbolt 4 Type-C port, one USB 20Gbps Type-C port and multiple 10Gbps and 5Gbps USB connections for high-speed peripherals. Network access comes via Intel 2.5Gb Ethernet and Wi-Fi 7 2x2 with Bluetooth 5.4 for wireless throughput. Storage uses a PCIe 4.0x4 NVMe SSD rated at 7450 MB/s read and 6900 MB/s write alongside a 10TB SATA hard drive with 256MB cache.
