16GB Radeon RX 7800 XT for 1440p and 4K Gaming

This Sapphire Tech graphics card uses the AMD Radeon RX 7800 XT GPU with 3840 stream processors and 16GB GDDR6 memory on a 256-bit interface. Core clock runs at 2124 MHz and boost clock reaches 2430 MHz. It targets gamers and creators who need high frame rates at 1440p and playable 4K performance in modern titles. The card is sold in refurbished condition.

Check PCIe 4.0 x16 Slot and 700W Power Supply

Verify your motherboard has a free PCI Express 4.0 x16 slot and that your power supply delivers at least 700W with the required PCIe power connectors for a 263W TDP card. The board occupies 2.5 slots and measures 280 mm in length, so confirm case clearance and motherboard spacing. Ensure your monitor uses HDMI 2.1 or DisplayPort 2.1 for full resolution and refresh support.

Dual-Fan Cooler Fits ATX Builds

The double-fan cooler exhausts heat into the case, so plan front-to-rear airflow with intake and exhaust fans. Two and a half slot width may block an adjacent PCIe slot on tighter boards. One HDMI 2.1 and three DisplayPort 2.1 outputs drive up to four displays at 7680 x 4320 maximum resolution. DirectX 12 Ultimate and OpenGL 4.6 support cover current APIs.

Questions about this item

What comes with the refurbished Sapphire Radeon RX 7800 XT 21330-01-20G and what must be purchased separately?

The box contains the graphics card with its dual-fan cooler and the standard output bracket. A power supply of at least 700W with the required 8-pin connectors is not included and must be sourced separately.

How do I decide which memory configuration of the Sapphire Radeon RX 7800 XT 21330-01-20G to choose?

This model is offered in a single 16GB 256-bit GDDR6 configuration, so there is no alternative capacity or bus width to select.

What does the 2430 MHz boost clock mean once the Sapphire Radeon RX 7800 XT 21330-01-20G is installed in my system?

The 2430 MHz boost clock is the peak frequency the GPU can reach under load, while the 2124 MHz core clock is the guaranteed base speed; actual sustained speeds depend on cooling, power limit and driver behaviour.
