Low profile vs full height GPU

Low profile and full height are the two bracket heights of a PCIe add-in card. A low-profile card is about 69 mm tall and a full-height card 111 mm or more. NVIDIA's ConnectX-7 manual calls the short class half height, and Broadcom labels its adapters LP-MD2 and FH-MD2. Slot count is a separate spec, covered in the single-slot and dual-slot entry.

Broadcom's low-profile 9600-16i adapter measures 155.52 mm by 68.77 mm, and its full-height 9670-24i measures 167.65 mm by 111.15 mm. NVIDIA's half-height ConnectX-7 cards measure 68.90 mm by 167.65 mm, and a full-height one 115.15 mm tall. NVIDIA lists the RTX A2000 as low profile, dual slot, 2.7 in. by 6.6 in. at 70 W. The RTX PRO 4000 Blackwell SFF Edition lists the same size and power. The RTX PRO 4000 Blackwell is 4.4 in. by 9.5 in., single slot, at 145 W. The RTX PRO 6000 Blackwell Workstation Edition is 5.4 in. by 12.0 in. at 600 W.

Check the height and length class the chassis lists for each slot before picking a card, since a full-height card does not seat in a low-profile slot. NVIDIA's low-profile cards above stop at 70 W. Budget for that ceiling when the workload needs more.
