Custom workstation for AI and rendering

This tower desktop combines a 24-core Intel Core i9-14900K processor with an Nvidia GeForce RTX 5090 graphics card. Sixty-four gigabytes of DDR5 memory and a one-terabyte NVMe SSD provide capacity for large datasets. The system ships with Windows 11 Pro installed and includes liquid cooling for sustained workloads.

PCIe 4.0 storage ceiling

The included Samsung 990 PRO drive connects through a PCIe 4.0 x4 interface, limiting sequential reads to 7450 megabytes per second and writes to 6900 megabytes per second. Four M.2 slots on the Z790 motherboard allow additional drives, but each will share the same generation bandwidth. Rear I/O offers 2.5-gigabit Ethernet, Wi-Fi 6 and Bluetooth 5.2 for network connectivity.

Thirty-two gigabyte GPU frame buffer

The RTX 5090 ships with 32 GB of video memory, which determines the maximum model size that fits in local memory without off-loading to system RAM. System memory can be expanded to 192 GB across four slots, but only the GPU memory capacity governs single-device inference and rendering limits.

Questions about this item

Should I pick the 64 GB DDR5 option or upgrade to the 192 GB maximum?

The system ships with 64 GB DDR5 installed across four slots; the board supports up to 192 GB if your workloads need more capacity.

What does the i9-14900K's 6.00 GHz boost mean for daily performance?

The 24-core CPU can reach 6.00 GHz on light threads while sustaining high clocks across all 32 threads for rendering and AI tasks.

Will the Samsung 990 PRO PCIe 4.0x4 drive hit its 7450 MB/s read speed on the Z790 motherboard?

Yes, the Z790 chipset provides full PCIe 4.0x4 lanes to the M.2 slot, so the SSD can deliver its rated sequential speeds.
