Yesterday it was the RX 7700 XT, today it’s the RX 7800 XT that’s making news. Indeed, following HXL’s claims about the 7700 XT’s Time Spy scores, Kopite7Kimi has put a coin in the machine.
RX 7800 XT: a score similar to the RX 6800 XT on Time Spy!
Before getting to the heart of the matter, a quick reminder. The 7800 XT is a brand-new card from AMD, announced at Gamescom at the end of August. The card features a Navi 32 GPU equipped with 60 compute units containing 3840 stream processors. When it comes to memory, AMD is generous… well, more so than NVIDIA, with 16 GB of GDDR6 and a 256-bit bus. Coupled with a frequency of 19.5 Gbps, memory bandwidth is 620.8 GB/s.
Now for the scores, via leaker Kopite7Kimi, we learn that the card clocks in at 19,000 pts on 3DMark Time Spy. Admittedly, these are only approximations, we imagine, to avoid burning out our sources. However, 19,000 pts puts the card up against its older-generation counterpart, the RX 6800 XT.

As a reminder, the card featured a substantial Navi 21-based GPU with no less than 4608 stream processors. It also featured 16 GB GDDR6 and a 256-bit memory bus. However, its memory bandwidth was lower: 512 GB, due to the lower speed of its memory: 16 Gbps.
Compared to the competition, AMD’s card would live up to its promise, outperforming NVIDIA’s RTX 4070. Now, it’s important to bear in mind that the scores are highly rounded. Likewise, you can’t form an informed opinion with a simple Time Spy score, which only represents one use case… And above all, this is a synthetic benchmark.
