Low-Profile RX 6400 Card

The GIGABYTE GV-R64D6-4GL is a low-profile graphics card built on the AMD Radeon RX 6400 GPU with 768 stream processors. It targets compact systems that need a PCI Express 4.0 add-in board for 1080p gaming or multi-monitor productivity. The 4GB GDDR6 frame buffer and 64-bit memory interface keep the physical footprint small while supporting modern display outputs.

Sustained 53W Load Behaviour

With a 53W thermal design power the card draws modest energy under continuous load. The game clock of 2039 MHz is the typical operating frequency during extended sessions, while the 2321 MHz boost clock appears only in short bursts. The 16000 MHz effective memory clock feeds the 64-bit bus steadily, so frame-times remain consistent without aggressive throttling.

Dual-Fan Cooling at 53W

A dual-fan cooler handles the 53W heat load in a two-slot, 182 mm long form factor. At typical gaming power the fans spin at low RPM, keeping acoustic output quiet for living-room or office builds. A 350W power supply is sufficient for the whole system, and the single 8-pin connector is not required, simplifying cable routing in tight chassis.

Questions sur cet article

How much heat does the 53 W TDP put into a case that runs all day?

The card draws 53 W at its thermal design power, so a 350 W power supply is recommended and a standard low-profile cooler with two fans handles the heat.

What slot and power connectors must my motherboard and PSU provide for this RX 6400?

You need a PCI Express 4.0 x16 slot and a 350 W power supply; the board draws all power from the slot so no extra PCIe cables are required.

Will the 64-bit GDDR6 memory and PCI Express 4.0 link limit performance on an older PCIe 3.0 system?

The card uses a PCI Express 4.0 x4 electrical interface, so on a PCIe 3.0 motherboard bandwidth is halved, which can reduce frame rates in memory-heavy titles.
