Sapphire Pulse RX 6400 4GB graphics card

This Sapphire Pulse Radeon RX 6400 card carries 4GB of GDDR6 memory on a 64-bit interface and runs at a boost clock of 2321 MHz. It is built for 1080p gaming and everyday multimedia on systems that need a low-power PCIe 4.0 add-in board.

Check PCIe slot power supply and system memory

Verify the motherboard has a free x16 PCI Express slot and that the power supply can deliver at least 350W for the whole system. The card draws 55W and requires a minimum of 8GB system memory, with 16GB recommended for best results.

Dual display outputs support two monitors

One HDMI port and one DisplayPort 1.4 connection enable multi-monitor setups up to 7680 x 4320 resolution. The single-fan cooler keeps the 55W TDP in check without extra power cables or bulky heatsinks.

Questions about this item

Does the Sapphire PULSE RX 6400 include any power cables or adapters in the box?

The card draws up to 55 W entirely from the PCI Express 4.0 slot, so no external power cables or adapters are required or included.

Should I choose the 4 GB GDDR6 version or look for a larger memory option?

This model is only offered with 4 GB of GDDR6 on a 64-bit bus; there is no higher-capacity variant of the same card.

What does the 2321 MHz boost clock deliver in a typical gaming PC?

The 2321 MHz boost clock is the peak frequency the GPU can reach under load; actual in-game clocks will vary with temperature, power limit and workload.
