Pulse Radeon RX 7900 XT identity
The Sapphire Tech Pulse Radeon RX 7900 XT is a refurbished graphics card built on AMD RDNA 3 architecture for enthusiasts who want high frame rates at 4K resolution. It delivers 5376 stream processors and a 2450 MHz boost clock to handle demanding titles and creative workloads. The 20GB GDDR6 frame buffer supports large texture sets and multi-monitor setups.
20GB 320-bit GDDR6 memory
The 20GB memory capacity on a 320-bit bus is the specification that determines whether this card fits a build targeting 4K gaming or heavy compute tasks. It provides 80MB AMD Infinity Cache and 20000 MHz effective memory clock to keep bandwidth high. This configuration reduces the need to offload assets to system RAM.
Power and slot requirements
The card draws up to 331W and requires a 750W power supply with two 8-pin connectors. It occupies a PCI Express 4.0 x16 slot and needs a case with enough length clearance for a triple-fan cooler. DisplayPort 2.1 and two HDMI ports drive up to four displays at 7680 x 4320 resolution.

Questions about this item
How does the 2450 MHz boost clock behave under sustained load?
The 2450 MHz boost clock is the peak frequency the GPU can reach when thermal and power headroom allow; actual sustained clocks depend on case airflow and the 331 W thermal design power.
What bandwidth does the PCI Express 4.0 x16 link provide for this card?
PCI Express 4.0 x16 delivers up to 32 GB/s bidirectional throughput, which is the practical ceiling for data moving between the GPU and the rest of the system.
What case clearance and power connectors does the triple-fan cooler require?
The triple-fan design occupies three expansion slots and needs two 8-pin power connectors fed from a minimum 750 W supply.
