AMD RX 7900 XT vs 7900 GRE: Which is the best GPU?

The AMD RX 7900 XT and 7900 GRE are two interesting GPUs. They are based on the same architecture and sport the same 7900 monikers, which makes people think they have similar performances. However, that's not the case at all, and there's a significant performance difference between the two graphics cards. But is it big enough to justify the price differences between the two?

Let's find out with a few gaming benchmarks of the AMD RX 7900 XT and 7900 GRE.

Here are the specs of the AMD RX 7900 XT and 7900 GRE:

Specifications	AMD RX 7900 XT	AMD RX 7900 GRE
Architecture	RDNA 3	RDNA 3
Shader cores	5376	5120
RT cores	84	80
TMUs	336	320
ROPs	192	160
Base core clock speed	1387 MHz	1287 MHz
Boost core clock speed	2394 MHz	2245 MHz
Memory capacity	20 GB	16 GB
Memory bus width	320-bit	256-bit
Memory bandwidth	800 GB/s	576GB/s
Manufacturing node	5nm, 6nm	5nm, 6nm
Thermal design power (TDPs)	300W	260W
Price	$689	$529

The main differences between the two GPUs lie in the shader core count, core clock speeds, and the memory system. The memory system, in particular, is significantly different between the two graphics cards.

The AMD RX 7900 XT has more memory capacity, and its memory chips are much faster than the ones in the AMD RX 7900 GRE. The faster VRAM combined with higher core clocks and shader count should lead to a significant performance difference between the two cards.

It's time we take a look at the real-world gaming benchmarks of the two GPUs to see just how much of a difference there is between them.

Note: The two video cards were tested at 1440p resolution with high/ultra graphics settings. All the FPS numbers have been sourced from the ErockOnTech channel on YouTube.

Here's how the AMD RX 7900 XT and 7900 GRE perform in gaming:

Games	AMD RX 7900 XT	AMD RX 7900 GRE
Assassin's Creed Valhalla	151 FPS	126 FPS
Cyberpunk 2077	120 FPS	104 FPS
God of War	158 FPS	131 FPS
Hogwarts Legacy	142 FPS	111 FPS
Starfield	99 FPS	86 FPS
Helldivers 2	91 FPS	78 FPS

On average, the AMD RX 7900 XT is 19.6% faster than the 7900 GRE. The difference is even more pronounced in some specific games. For example, in Hogwarts Legacy, the former GPU is around 28% faster than the latter.
