Sapphire Pulse RX 6400 Low-Profile Card

This Sapphire Pulse graphics card uses the AMD Radeon RX 6400 GPU with 4GB of GDDR6 memory. It fits a single-slot, low-profile form factor for compact builds. The PCI-Express 4.0 interface connects to compatible motherboards. It targets users adding discrete video to small chassis.

Thermals and Power on a Single Slot

The single-slot cooler manages heat within the low-profile envelope. Game clock runs up to 2039 MHz while boost reaches up to 2321 MHz. The 64-bit memory interface operates at 16 Gbps. Power draw stays within the slot limit for simple installation.

Included Bracket Enables Small Chassis

A low-profile bracket is supplied to match the single-slot PCB. This allows installation in slim enclosures where full-height cards cannot fit. Digital output supports up to 7680×4320 resolution. No extra software bundle alters the core driver experience.

Questions about this item

How do I install the low-profile card in a single-slot chassis without blocking the bracket?

Align the single-slot low-profile bracket with the PCI-Express 4.0 x16 slot, press straight down until the latch clicks, then secure the bracket screw; the step people miss is forgetting the half-height bracket swap before mounting.

What maintenance will the 4GB GDDR6 card need after extended marine use?

Clean the heatsink fins and single fan intake with compressed air every few months to stop salt dust build-up; no thermal-pad replacement schedule is published by the maker.

At what point does the 64-bit memory interface become the bottleneck during sustained load?

The 64-bit DDR6 bus limits sustained memory throughput to 16 Gbps, so texture-heavy workloads at 7680×4320 hit bandwidth saturation before the 2321 MHz boost clock can be fully utilised.
