Thanks to hardware enthusiast momomo_us on X, details about AMD’s upcoming RX 9070 series have leaked. According to the leak, the RX 9070 XT and RX 9070 will feature 16GB of GDDR6 memory and a higher number of Stream Processors (SPs) compared to the RDNA 3 models. However, it’s always wise to take such leaks with a grain of salt, even from reliable sources.
To recap, AMD unveiled RDNA 4 at CES but withheld specifics on its specs and performance. Despite numerous leaks hinting at a reveal this month, AMD has promised to share more details later this quarter. We managed to get glimpses of Navi 48, the die powering the RX 9070 series, which is nearly 390mm2. Rumors suggest that the RX 9070 XT rivals the RTX 4080 Super in raster performance and the RTX 4070 Ti Super in ray tracing, though these claims should be met with skepticism.
| GPU | Architecture | Stream Processors | Compute Units | VRAM | Memory Speed | Memory Bus Width | Memory Type | Bandwidth | Base / Boost Clocks | PCIe Support |

| RX 9070 XT* | RDNA 4 | 4,096 | 64 | 16GB | 20 Gbps | 256-bit | GDDR6 | 640 GB/s | 2.40 GHz / 2.97 GHz | PCIe 5.0 |
| RX 9070* | RDNA 4 | 3,584 | 56 | 16GB | 20 Gbps | 256-bit | GDDR6 | 640 GB/s | 2.07 GHz / 2.52 GHz | PCIe 5.0 |

| RX 7900 XT | RDNA 3 | 5,376 | 84 | 20GB | 20 Gbps | 320-bit | GDDR6 | 800 GB/s | 1.38 GHz / 2.39 GHz | PCIe 4.0 |
| RX 7900 GRE | RDNA 3 | 5,120 | 80 | 16GB | 18 Gbps | 256-bit | GDDR6 | 576 GB/s | 1.28 GHz / 2.24 GHz | PCIe 4.0 |
| RX 7800 XT | RDNA 3 | 3,840 | 60 | 16GB | 19.5 Gbps | 256-bit | GDDR6 | 624 GB/s | 1.29 GHz / 2.43 GHz | PCIe 4.0 |
| RX 7700 XT | RDNA 3 | 3,456 | 54 | 12GB | 18 Gbps | 192-bit | GDDR6 | 432 GB/s | 1.43 GHz / 2.54 GHz | PCIe 4.0 |
The tipster claims that AMD’s RX 9070 series will support PCIe 5.0, similar to Nvidia’s Blackwell series. The RX 9070 XT is said to have 16GB of 20 Gbps memory on a 256-bit interface and 4,096 SPs, translating to 64 Compute Units (CUs) if AMD maintains the RDNA 4 core layout. With slower GDDR6 memory, the RX 9070 XT’s bandwidth is 640 GB/s, which is lower than the RX 7900 series. The RX 9070 XT is expected to achieve a boost clock of 2.97 GHz, with AIB models likely surpassing the 3 GHz mark.
As per the leak, the non-XT RX 9070 will also have a 16GB frame buffer but with a reduced core count of 3,584 SPs or 56 CUs. Its memory setup is similar, also providing 640 GB/s of bandwidth. However, its base and boost clocks are lower, with the boost clock topping out at 2.52 GHz, nearly 500 MHz less than the RX 9070 XT. This significant reduction might result in a lower Total Graphics Power (TGP), possibly under 200W, but that’s just speculation.
To compete with DLSS, AMD has developed FSR 4, available only on the RX 9000 series, and powered by hardware-based machine learning. We’ll have to wait and see how this technology compares to Nvidia’s new offerings until these GPUs are released. AMD might be waiting to see how Blackwell performs before setting RDNA 4’s pricing. Either way, we have to be patient for AMD’s highly anticipated reveal.
