AMD has officially announced the Radeon RX 7900 GRE, a model that was initially supposed to be released only in China but will eventually reach the whole world. It’s a slightly trimmed version of the 7900 XT, bringing it down from 84 compute units to 80, which yields 5,120 shaders. The frequencies are also lowered to a turbo 2245 MHz instead of 2390 MHz.
The worst hit is the memory bandwidth, which goes from a 320-bit bus to a 256-bit one, which leaves it at 576 GB/s because it uses 16 GB of 18 Gb/s GDDR6 memory instead. from 20 GB to 20 Gb/s. That also reduces the Infinity cache to a mere 64MB. It’s a way to make games that are more memory dependent artificially throttle their performance. Consumption is reduced from 300 W to 260 W.
AMD has put a RRP of $649, so it competes with the RTX 4070 and its RRP of $599. The RRP will be seen, but the Radeons are well below it right now, so it could still be a very interesting graphics card. The chip that integrates this graphics card is slightly smaller than the Navi 31 since it includes 54,000 M of transistors instead of 58,000 M.
The first analyzes that have appeared from Chinese media suggest that it has a performance around 20% below that of the RX 7900 XT, but depending on the game it can have 0-20% more power than the RTX 4070 It varies a lot depending on the game, but the average would be around 10% more power.
