Leaked AMD Radeon RX 7600 GPU Reference Card Design Emerges
We have seen a few examples of custom design/board partner Radeon RX 7600 graphics card models via leaks over the past two weeks - and AMD's alleged reference design has made an appearance this weekend, only fours days prior to the official product launch date (May 25). The leaked images once again come courtesy of VideoCardz - the set of two photos show a dual-fan setup on a mostly black shroud with the company's simple "Radeon" logo positioned near the top - this design seems to be missing an underlining strip of RGB (as seen on the big boy cards).
The picture of the card's flipside depicts a very plain looking backplate. The overall aesthetic is not too far removed from the existing high-end Radeon RX 7900 XT and 7900 XTX reference siblings, although this leaked entry-level offering is tiny in comparison - it is reported to be just under 21 centimeters in length (versus the 7900 XT at 27.6 cm and 7900 XTX at 28.7 cm). The RX 7600 MBA (made-by-AMD) card is said to be two slots wide.

Unlike the hundreds of 6700XT/6750XT SKUs across the entire spectrum of manufacturers, limited quantities of just three SKUs (one of which isn't great) is probably why many people don't even know it exists.
The regular RX 7600 appears to be fully-enabled Navi33 silicon, so there's no room for an XT with a higher core count on Navi33. It's possible the XT will be the same 2048 shaders with an overclock and double the VRAM - but this is just speculation at the moment.
Navi32 was delayed apparently, and they will likely carve the 7800 and 7700-series out of it - so I'm not sure there will be a 7600XT too - five different configurations of the same die seems quite unlikely for AMD, they only had two for (desktop) Navi22 in the 6000-series.
The 7600XT results all over the web are just inaccurate rumour-mill misreporting the RX7600 we now know to be officially launching on Thursday. Navi32 is apparently 60CU (so 3840 shader cores), confirmed by a leak from AMD themselves via AMD's own ROCm development team. 60CU seems far too big to be used for the 7600XT. Knocking it down to 45CU and 192-bit still makes it 41% faster than the RX7600 which is a huge performance (and price) gap. I suspect the harvested part with 42-45CU@192bit w/12GB VRAM is eventually going to be the 7700-series and the 56-60CU@256bit w/16GB VRAM will be the 7800-series.
Bear in mind that Navi32's original released date was supposed to be Q3 2023 and in an interview with AMD's Sam Naffziger (the chiplet guy)* He mentioned to Steve Burke of GN that Navi31's chiplets weren't stable at the clockspeeds AMD originally intended, so they were forced to downclock the 7900XT and 7900XTX. Direct from AMD's chief RDNA3 chiplet engineer, is confirmation that they are delaying Navi32 to fix those issues in hardware, because they couldn't fix it in software for Navi31.
That means that Navi32's is extremely unlikely to make its original Q3 2023 launch date, so we're more likely expecting no new RDNA3 launches faster than the RX 7600 until Christmas.
* edit - might have actually been a different GN inteview with Mike Mantor from RTG instead, but it was one of those November 2022 7900XTX launch coverage videos.
A 7600 xt with 16 Go would really be a damn good budget deal.
