Asrock Radeon RX 7800 XT Phantom Gaming is the first graphics card with RDNA 3 Navi 32 GPU, which has now been spotted in the official documentation. As expected, the direct successor to the Radeon RX 6800 XT will again be based on 16 GiByte GDDR6.
The Asrock Radeon RX 7800 XT Phantom Gaming is the first graphics card with RDNA 3 GPU Navi 32 which has now been spotted in the official documentation. As an entry in the Eurasian Economic Commission (“EEC”) database confirms, the direct successor to the Radeon RX 6800 XT will once again be based on 16GB GDDR6, as expected. And the producers’ full names also leave no doubt about it.

As can be seen from the database entry, Asrock Radeon RX 7800 XT Phantom Gaming 16G and Phantom Gaming 16G OC are registered. Both graphics cards are expected to use Navi 32 with its four memory controllers (“MCD”) and a 256-bit memory interface, PCGH reported last week.
Unlike the Radeon RX 6000 series, when the Radeon RX 6900 XT, Radeon RX 6800 XT, and Radeon RX 6800 were all based on the large Navi 21 GPU, this time AMD probably wants to separate the large Radeon RX 7900 series from the existing Radeon RX 7800 series. below. While the monolithic Navi 33 remains reserved for the Radeon RX 7600 series, the Radeon RX 7700 series can also rely on Navi 32.
| AMD Radeon RX 7900 series | AMD Radeon RX 7800 series | AMD Radeon RX 7700 series | AMD Radeon RX 7600 series | |
|---|---|---|---|---|
| building | RNA 3 | RNA 3 | RNA 3 | RNA 3 |
| GPU build | Multi-chip modules (“MCM”) | Multi-chip modules (“MCM”) | Multi-chip modules (“MCM”) | congener |
| GPU | Navi 31 | GPS 32 | GPS 32 | GPS 33 |
| graphics memory | Up to 24 GB | up to 16 GB | Up to 12 GB | up to 8 GB |
| user interface | up to 384 bits | up to 256 bits | up to 192 bits | up to 128 bits |
While the monolithic die for Navi 33 is manufactured at 6 nm at TSMC, AMD is also adopting a hybrid manufacturing approach for Navi 31 for Navi 32. This means that the complex graphics die (“GCD”) is manufactured at 5 nm, while all four can Fabricate memory controller dies (“MCD”) at 6 nm.
