This reminds me a lot of the RX 480 launch. The RX 480 4GB was about $250 at launch in 2023 dollars, compared to $270 for the RX 7600. The 480 reference card had a 6-pin power connector but it drew more power than the spec allowed until a firmware update, and the 7600 reference also has a power connector issue (but this time customers won't see the issue). Neither was power-efficient for its time (but the RX 480 was AMD's most power-efficient graphics card in its time, whereas the 7600 is the least-efficient of RDNA3). I almost like it. If it had 16 PCIe lanes it'd be a very nice upgrade from my RX 480 4GB. But it only has 8 lanes, and I saw this coming so I replaced my RX 480 4GB months ago with a full x16 card.
(I know, usually there's no significant performance hit to PCIe 3.0 x8 as Tech Power Up tested on the RX 6600 XT. But the 7600 outperforms the 6650 XT, so it needs more bandwidth, and in the worst case the performance loss may be over 10%, which means it'll perform on par with the 5700 XT which can be bought used for much cheaper and has a full PCIe 4.0 x16 interface.)
Wait. The 5700 XT performs as well in 4K, probably thanks to its 256-bit memory interface. Maybe I'm being too optimistic about this card; it's a little bit of an electricity guzzler, it only has 8GB of memory, it struggles at higher resolution where it's cache isn't enough to make up for it's 128-bit memory, and it has only 8 PCIe lanes. This is no RTX 4060 Ti, which costs 48% more and has all the same downers except power efficiency while only performing 25% better in today's games, but I guess the RX 7600 is still a little disappointing.
