20-Core Ultra 7 Workstation

This desktop combines a 20-core Intel Core Ultra 7 265K processor with 128GB DDR5 memory and an Nvidia GeForce RTX 5080 16GB graphics card. It targets professionals who need local compute for rendering, modelling and AI learning workloads alongside high-frame-rate gaming. The system ships with Windows 11 Pro on an 8TB NVMe array built from two 4TB Samsung 990 PRO drives.

PCIe 4.0 Storage And Connectivity Limits

The two M.2 SSDs operate over PCIe 4.0 x4, delivering sequential reads up to 7450 MB/sec and writes up to 6900 MB/sec. Rear I/O includes one Thunderbolt 4 Type-C port, one USB 20Gbps Type-C, three USB 10Gbps and three USB 5Gbps ports. Wireless uses Wi-Fi 7 2x2 with Bluetooth 5.4; wired networking is Intel 2.5Gb Ethernet.

Pre-Built Liquid Cooling And Case Clearance

A 240mm AIO cooler arrives installed on the LGA 1851 socket, so no CPU mounting is required. The Ceres 300 mid-tower case accepts front and rear 140mm fans at 1500rpm and provides bays for one 3.5in or two 2.5in drives. Builders adding extra storage must work within the 475mm depth and the four SATA 6Gbps headers on the Z890 TUF motherboard.

Questions about this item

Should I pick the 8 TB NVMe option or look for a larger capacity?

The build ships with two 4 TB Samsung 990 PRO drives in RAID 0, giving 8 TB total. Four M.2 slots exist on the Z890 board, so extra NVMe modules can be added later if more space is needed.

What does the 5.50 GHz boost clock mean when I am rendering or gaming?

The 20-core Ultra 7 265K can push up to 5.50 GHz on active cores, so heavy all-core workloads such as 3D rendering or AI training sustain high frequencies while the 240 mm liquid cooler keeps thermals in check.

How fast is the Thunderbolt 4 port on the rear I/O panel?

The rear Thunderbolt 4 Type-C connection runs at 40 Gbps, supporting fast external NVMe enclosures, docks and displays without bottlenecking the 7450 MB/s internal SSD reads.
