A highly plausible looking AMD Radeon RX 6600 series graphics card is doing rounds on the web. The card is purportedly an AMD reference-design OEM-trim "Navi 23" board. We know from recent rumors that the 7 nm "Navi 23" silicon powers the upcoming Radeon RX 6600 XT and RX 6600. The picture only shows a portion of the card, the back-plate as viewed toward the rear I/O, but the bar-code sticker is unmistakable. The sticker reveals the OEM to be PC Partner, which is known to make all OEM and retail reference-design AMD Radeon graphics cards, which are marked "MBA" (made by AMD). You'll find a similar-looking bar-code sticker on all AMD reference-design cards, regardless of the AIB partner marketing it.

The bar-code sticker references "Navi 23 XT," which is very likely the Radeon RX 6600 XT. The card has 8 GB of GDDR6 memory, and its display outputs include one HDMI, and three DisplayPorts. Elsewhere in the picture, we get valuable insights into the design of the cooler, revealing that the card features an aluminium fin-stack heatsink with one or more axial fans (top-flow), rather than a channel-type lateral blower-type cooling solution. The "Navi 23" silicon is rumored to feature up to 32 RDNA2 compute units that amount to 2.048 stream processors, a PCI-Express 4.0 x8 host interface, much like the RX 5500 XT, and a 128-bit wide GDDR6 memory interface.

Specifications of AMD's upcoming mid-range Radeon RX 6600 XT and Radeon RX 6600 recently surfaced, and now we see screenshots of TechPowerUp GPU-Z confirming the two. The RX 6700 XT is shown featuring 2,048 stream processors, 128 TMUs, 32 ROPs, and a 128-bit wide GDDR6 memory interface with 8 GB of memory. The RX 6600 (non-XT), on the other hand, is shown featuring 1,792 stream processors, 112 TMUs, 32 ROPs, and the same 8 GB of GDDR6 memory. Both chips feature PCI-Express Gen 4 support, but much like the RX 5500 XT, the "Navi 23" only has 8 PCIe lanes. GPU-Z also seems to detect raytracing.

Even as the desktop Radeon RX 6700 (non-XT) is nowhere in sight, AMD is planning to scale its RDNA2 graphics architecture further down, with the RX 6600 XT and RX 6600. Regulatory filings by board partner ASRock with the Eurasian Economic Commission (EEC), for the unreleased RX 6600 XT and RX 6600, hit the web, courtesy Komachi Ensaka. The filings list out internal SKU numbers. An interesting thing to note here is that both the RX 6600 XT and RX 6600 could have 8 GB of memory as standard. Given that the RX 6700 series is already pulling up to 12 GB over a 192-bit wide memory bus, it's likely that the RX 6600 series could use a narrower 128-bit bus for its 8 GB, use the fastest 16 Gbps memory chips (at least on the XT variant), and attempt to shore up memory bandwidth using Infinity Cache. A market launch typically follows EEC filings by 3 months, so the RX 6600 series could see a late-Summer launch.
