It has been reported that the RX 7800 has 16 GB of VRAM and the RX 7700 has 12 GB of VRAM. (Intel Inside)In September, AMD plans to release the RX 7800 and RX 7700. The mid-range Navi 32 GPU is rumoured to be included in the cards that could be the final RDNA 3 offers. Leaker All_The_Watts has posted some new 3DMark Time Spy Graphics numbers, suggesting that the RX 7800 and RX 7700 may be superior to the RTX 4070 and RTX 4060 Ti.
The Navi 32-based RX 7800 and RX 7700 GPUs from AMD are rumoured to be unveiled at Gamescom 2023 next month, with a September release date aim. A couple of days ago, leaker All_The_Watts posted the results of the 3DMark Time Spy benchmark for both GPUs on Twitter, giving us a glimpse of the prospective efficiency profile of these chips.
Results from the 3DMark Time Spy Graphics benchmark were published by All_The_Watts to place the RX 7800 at 18,957 and the RX 7700 at 15,568. To put these numbers in perspective, @harukaze5719 has created a wonderful chart that compares the rumoured performance of the RX 7800 and RX 7700 to that of several older and newer AMD and NVIDIA GPUs.
In terms of performance, the RX 7800’s score of 18,957 is superior by 5.2%, 5%, and 16% to those of the RTX 4070 (18,007), RTX 3080 10 GB (18,048), and RX 6800 (16,352). If these results hold, the RX 7800 will be a significant improvement over the RX 6800, but it will still fall short of the RX 6800 XT, which has a 3DMark Time Spy Graphics score of 18,711.
Looking at the next set of numbers, the RX 7700’s 15,568 score places it 15% ahead of the RTX 4060 Ti’s 13,539 score, 3.5% ahead of the RTX 3070 Ti’s 15,032 score, and 5% behind the RX 6800.
Compared to the RTX 4070 and RTX 4060 Ti, the RX 7800 and RX 7700 are purportedly quicker. It has been suggested that both GPUs could deal damage to Team Green’s competition. According to All_The_Watts, the RX 7800 will set you back $549, while the RX 7700 will set you back $449.
Assuming both Navi 32 cards perform as advertised and AMD prices the boards as expected, the GPUs might be best-sellers in an industry plagued by poor product introductions. We should, as usual, reserve judgement until the cards are commercially accessible and in the hands of impartial testers.
