Pros And Cons

Comparison Table

Architectural Differences

• Process Node: The RX 7800 XT uses the “multi-node design” like the rest of the RDNA 3 lineup, using a TSMC’s 5nm node for the GCD and 6nm for the MCD. In contrast, the RTX 3080 uses Samsung’s 8nm node.
• Frequencies: The RX 7800 XT clocks 1295MHz (core) at the base setting while the RTX 3080 runs faster at 1440MHz. As for boost frequencies, the RX 7800 XT pushes to 2430MHz compared to the RTX 3080’s speed of 1710MHz.
• VRAM: As has been the case so often, AMD takes the win regarding memory capacity with 16GB over 10GB of Nvidia’s Ampere card. Concerning memory type, though, the RTX 3080 uses superior GDDR6X memory chips over GDDR6.
• TDP: The RX 7800 XT has a TDP of 263 watts, about 21% lower than the RTX 3080 (320 watts).
• Supported Technologies: The RX 7800 XT supports FSR 3, while the RTX 3080 supports all DLSS versions older than DLSS 3. Furthermore, both cards use second-generation ray tracing accelerators from their respective manufacturers.

The introduction of AMD’s midrange RX 7000 series cards has raised new questions concerning how they stack up versus its longtime rival, Nvidia GPUs. Today, I’ll compare the RX 7800 XT vs RTX 3080 to find the better GPU in terms of performance, efficiency and value.
