Leaked information from hardware enthusiast momomo_us on X suggests details about AMD's upcoming RX 9070 series GPUs. The leaks point towards the RX 9070 XT and RX 9070 carrying 16GB of GDDR6 memory and offering an increase in Stream Processor (SP) counts compared to their RDNA 3 predecessors. Remember to treat this information with caution, even with the leaker's strong track record.
AMD RDNA 4 and Navi 48
AMD unveiled the RDNA 4 architecture at CES, but remained tight-lipped on specific details. The Navi 48 die, which powers the RX 9070 series, is estimated to be around 390mm². Performance leaks suggest that the RX 9070 XT could rival the RTX 4080 Super in raster performance and the RTX 4070 Ti Super in ray tracing.
RX 9070 Series Specifications (Leaked)
According to the leak, both the RX 9070 XT and RX 9070 will support PCIe 5.0. The flagship RX 9070 XT is rumored to feature:
- VRAM: 16GB of 20 Gbps GDDR6 memory
- Memory Interface: 256-bit
- Stream Processors: 4,096 (64 Compute Units)
