The AMD Radeon RX 7900 GRE vs RX 6800 XT battle is pretty engaging. Both GPUs come from the same brand and cater to individuals looking for top-notch gaming performance. Since they are a generation apart, some differences set them apart. However, picking one over the other is a complete headscratcher.

So, should you choose the older card, which remains powerful enough to handle modern titles and is available at a lower price, or opt for the new series card with its advanced architectural developments? This is exactly what we will determine in this AMD Radeon RX 7900 GRE vs RX 6800 XT analysis.

The biggest advantage of the AMD Radeon 7000 series over the older series lies in its architecture. The RX 7900 GRE is built on RDNA 3.0 with a 5nm process node. This new architecture brings substantial advancements in performance, efficiency, and features compared to RDNA 2.0, which the RX 6800 XT is based on.

However, despite being a generation old, the clocks, whether it is base, game, or boost, all are faster in the RX 6800 XT. Moreover, it has more cache memory as well.

Below, you can check other technical configurations:

Both cards have 16GB of VRAM, which is more than enough to run your favorite titles without breaking a sweat. However, the new Team Red card is more efficient owing to the small process node and lower TDP. This also means that it will stay relatively quieter and cooler compared to its older equivalent.

The RX 7900 GRE has more shading units and RT cores, but it also comes with a higher pricetag.
