The AMD Radeon RX 6600 XT and RX 6600 are two upcoming mid-range graphics cards that appear set to launch on August 11th. The Radeon RX 6600 XT is expected to feature all 2048 Stream Processors of the Navi 23 GPU and will be paired with 8 GB of GDDR6 memory. The Radeon RX 6600 will feature the same Navi 23 GPU but with 1792 Stream Processors and will be paired with 4 GB or 8 GB of memory. The Navi 23 GPU is already present in the mobile RX 6600M and the workstation Radeon Pro W6600 which should give an indication of potential performance. We have limited information for the MSRP of the two cards but they will likely come in under 400 USD however final retail prices are unknown. The August 11th date is specifically stated to be the launch day so we will likely see an announcement in the coming weeks.

Update Jul 22nd: We have received an update from YouTuber Coreteks who claims that only the RX 6600 XT will launch on August 11th and that the RX 6600 has been delayed until September or October.

Pictures of a made-by-AMD (MBA) Radeon RX 6600 XT OEM graphics card hit the web. This particular card has all the signs of an MBA card, including the AMD logo near the PCIe fingers, and barcode stickers of the font used by PC Partner, the OEM that makes MBA cards. This isn't necessarily the reference card whose renders are floating on the web, but one that AMD supplies to pre-built desktop manufacturers.

The compact card appears roughly 18-20 cm in length, is dual-slot, and uses a single 8-pin PCIe power input. Its cooling solution uses an aluminium mono-block heatsink that's ventilated by a pair of 80 mm fans. The person with access to this sample put out performance numbers from the internal benchmark of a game popular in China, called Ludashi, as well as how it compares to other graphics cards in this test. The results are interesting. The RX 6600 XT apparently beats or matches the GeForce RTX 3060 Ti, which means it should have a comfortable lead over the RTX 3060, at least in this test. AMD is expected to launch the RX 6600 XT in the retail channel, on August 11, 2021.

AMD is allegedly preparing for an August 2021 debut of its Radeon RX 6600 XT graphics card in the retail segment, according to tech YouTuber Coreteks. Released exclusively as custom-design cards, through the company's AIB partners, the card will reportedly come with an MSRP price of USD $399, or roughly $100 less than that of the RX 6700 XT (which is being scalped for north of $800). The lack of a reference-design (MBA) model in the retail channel means that the card will not be sold through the AMD website.

The Radeon RX 6600 XT will reportedly be based on the 7 nm "Navi 23" silicon, although it remains to be seen if it maxes the silicon out. 8 GB will be the standard memory amount, across a 128-bit wide GDDR6 memory interface, cushioned by a 32 MB Infinity Cache. As for performance, Coreteks predicts that the RX 6600 XT will perform ±5% of the RX 5700 XT and the GTX 1080 Ti, which could make it a formidable card for AAA gaming at 1080p, or at 1440p with FSR.

AMD board partner PowerColor's website briefly showed product categories for graphics cards based on the upcoming Radeon RX 6600 XT and Radeon RX 6600 graphics processors. This would mean that a formal launch of the two is just around the corner. Both SKUs are reportedly based on the 7 nm "Navi 23" silicon. The RX 6600 XT maxes it out, featuring 2,048 stream processors, while the RX 6600 is slightly cut down, in featuring 1,792 of them. The "Navi 23" silcon is based on the same RDNA2 graphics architecture as the rest of the RX 6000 series, which means DirectX 12 Ultimate support, including raytracing. Both feature 8 GB of video memory, whereas the RX 6600 also comes in 4 GB. Both memory options use 16 Gbps GDDR6 memory, over a 128-bit wide memory bus. PowerColor is expected to design a variety of custom-design products based on the two.

AMD announced during CES 2021 that they would launch various new RDNA2 desktop and mobile products in 1H 2021 including dual and single fan Radeon graphics cards. The dual-fan variant turned out to be the AMD Radeon RX 6700 XT which was launched in March but we are yet to see anything of the single-fan card until recently. This single-fan card is allegedly the RX 6600 XT and leaked renders of it align with what AMD showed during CES giving further validity to the leak. The render shows a black and silver design with red accents keeping with other RDNA2 cards and a single 8-pin power connector. The AMD Radeon RX 6600 XT is set to feature a Navi 23 GPU paired with 2048 Stream Processors paired with 8 GB of GDDR6 memory.

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.

AMD is preparing to round-out its RX 6000 series lineup with the upcoming RX 6600 XT and RX 6600, introducing true midrange GPUs to their latest generation RDNA2 architecture. According to recent leaks, both graphics cards should feature AMD's Navi 23 chip, another full chip design, instead of making do with a cut-down Navi 22 (even though that chip still only powers one graphics card in the AMD lineup, the RX 6700 XT).

According to the leak, the RX 6600 XT should feature 2048 stream processors and 8 GB of GDDR6 memory over a 128-bit memory bus. The RX 6600, on the other hand, is said to feature a cut-down Navi 23, with only 1796 stream processors enabled out of the original silicon design, whilst offering the same 8 GB GDDR6 over a 128-bit memory bus. There are even some benchmark scores to go with these leaks: supposedly, the RX 6600 XT scores 9,439 points in 3DMark Time Spy (Graphics), while the RX 6600 card scores 7,805 points. Those scores place these cards in the same ballpark as the RDNA-based RX 5700 XT and RX 5700. It's expected that these cards feature a further cut-down 32 MB of Infinity cache - half that of the RX 6700 XT's 64 MB. With die-size being an estimated 236 mm², AMD is essentially introducing the same performance with 15 mm² less area, whilst shaving some 45 W from that cards' TDP (225 W for the RX 5700 XT, and an estimated 180 W for the RX 6600 XT).

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.
