HP AMD Radeon RX 6400 4GB GDDR6 Low Profile Graphics Card
85 in stock
Add modern, reliable graphics to compact and small-form-factor systems with the HP AMD Radeon RX 6400. Built on AMD’s RDNA™ 2 architecture with 4GB of GDDR6 memory, this low-profile, single-slot card delivers smooth 1080p productivity and light gaming while drawing just 53 watts — entirely from the PCIe slot, with no supplementary power connector required.
A full-length aluminum heatsink paired with a single low-noise fan keeps the card cool and quiet, and the low-profile board fits both small-form-factor and standard desktops. Choose your PCIe bracket at checkout — low-profile, full-height (tall), or both — so it drops straight into HP and other SFF machines as easily as a full-size ATX tower.
Dual digital outputs — 1× DisplayPort 1.4 and 1× HDMI 2.1 — drive two high-resolution displays for office, point-of-sale, digital-signage, and home-theater builds. Hardware H.264 and H.265 (HEVC) decoding keeps everyday video playback smooth and efficient. (Note: the Navi 24 media engine does not include hardware video encoding or AV1 decode.)
This is a brand-new OEM unit (HP spare M99977-001) in bulk packaging — no retail box.
