PCIe 4.0 x4 and Z890 connectivity limits

The 4TB Samsung 990 PRO SSD runs over a PCIe 4.0 x4 link, capping sequential reads at 7450 MB/sec and writes at 6900 MB/sec. The Z890 motherboard provides four M.2 slots and four SATA 6Gb/s ports, while rear I/O includes one Thunderbolt 4 Type-C, one USB 20Gbps Type-C, three USB 10Gbps and three USB 5Gbps ports. Networking uses Intel 2.5Gb Ethernet plus Wi-Fi 7 2x2 and Bluetooth 5.4.

32 GB GPU memory decides fit for large models

The RTX 5090 ships with 32GB of video memory, the single spec that determines whether this system can hold your working set in VRAM for large-batch training or high-resolution scene rendering. CPU boost reaches 5.50 GHz with 30 MB L3 cache, and the board supports up to 192 GB DDR5 across four slots. A 1000W 80 PLUS Gold PSU powers the build.
