The Lowest-Priced AMD 7900 XT Hits $729: Real Deals

Hardware Unboxed benchmarked it and IIRC it's pretty much 7800XT for China.

It's weird, though. Why wouldn't they just sell the regular 7800XT in China? It's cheaper.

After I wrote that, I did take a second look at the specs - and they're pretty weird. From Wikipedia, here are the specs where they differ:

So, it has 33.3% more compute elements, but only memory 92.3% as much memory bandwidth. This gives me the feeling that either some popular games in China are much more compute-bound, or that maybe it's a stealth compute card.

To the latter point, although the power numbers are about the same, look at how much lower the 7900 GRE's clocks are! If it overclocks well, it could perhaps make good on that compute element ratio.

Anyway, at stock settings, I think you're right that they probably don't perform differently enough to get too bothered over it. If I waited and scored a good deal on a RX 7800 XT, it could be a much better value.

Not sure about the specifics, the Chinese market is weird and I take it AMD knows better than I do. It could be just their way of making them feel special?
And although it is not my place to tell you what to buy, if you were willing to go as high as paying for the 7900 GRE why not see if you can get a good deal on Black Friday for a 7900 XT?
