AMD is widely expected to launch additional mid-range GPUs based on the RDNA 3 architecture this year, but an actual launch date has yet to be revealed.
After launching the flagship Radeon RX 7900 XTX and the high-end RX 7900 XT late last year, the Radeon RX 7000 series still only consists of those two GPUs and the mainstream RX 7600, with no upper mid-range alternatives to be found.
As of the latest rumor from serial leaker Tom at the Moore’s Law Is Dead YouTube channel, this might change sooner rather than later.
Reportedly, the next graphics cards in the RDNA 3/Radeon RX 7000, possibly as many as four new cards in total, could be unveiled as early as August.
Tom’s sources indicate that this will take place during the Gamescom fair, which takes place in August in Germany. The awaited RX 7800 XT is said to get the full Navi 32 chip with 60 compute units (CUs) along with 16 GB of GDDR6 graphics memory (VRAM) utilizing a 256-bit memory bus. Its TBP (total board power) value is allegedly 260 Watts.
AMD Radeon RX 7800 XT & RX 7700 XT Specs (Rumored)
| RX 7900 XTX | RX 7900 XT | RX 7800 XT* | RX 7700 XT* | |
|---|---|---|---|---|
| GPU | Navi 31 | Navi 31 | Navi 32 | Navi 32 |
| Compute Units | 96 | 84 | 60 | 54/48 |
| Memory Bus Width | 384-bit | 320-bit | 256-bit | 192-bit |
| VRAM Size & Type | 24GB GDDR6 | 20GB GDDR6 | 16GB GDDR6 | 12GB GDDR6 |
| TBP | 355 Watt | 300 Watt | 260 Watt | N/A |
| Launch MSRP | $999 | $899 USD | N/A | N/A |
The GPU referred to as the RX 7700 XT would use a scaled-down Navi 32 chip with either 48 or 54 CUs. As for VRAM, these graphics cards will ship with 12 GB of GDDR6 operating on a 192-bit memory bus.
Additionally, Navi 32 is also expected to appear in the shape of high-end laptop graphics chips, which is an area in need of competition as Nvidia is currently alone in the high-end mobile GPU space with its RTX 4000 series for laptops. Much like Nvidia, AMD could name these after higher-end variants, with the Radeon RX 7900 and RX 7800 designations being mentioned.
AMD reportedly postponed the launch of Navi 32 GPUs to avoid competing with the remaining stock of Navi 21-based RX 6000 series graphics cards that are currently selling at reduced prices.
As always when it comes to unconfirmed rumors, these names and specs are hardly set in stone, but we will know more once August and Gamescom nears.
