VideoCardz obtained AMD Radeon RX 9070 series specifications, which appear to be the official final configurations of the upcoming RDNA 4 GPUs. As we previously expected, the lineup consists of two models based on the Navi 48 GPU, which integrates 53.9 billion transistors on a 357 mm² die using a 4 nm (N5) process from TSMC. Both the RX 9070 XT and RX 9070 utilize identical memory configurations: 16 GB of GDDR6 memory running at 20 Gbps across a 256-bit bus, delivering 640 GB/s bandwidth. Each card implements 64 MB of 3rd Generation Infinity Cache and supports PCIe 5.0 x16 interface standards. The RX 9070 XT features 64 RDNA 4 Compute Units, equating to 4096 Stream Processors, 64 Ray Accelerators, and 128 AI Accelerators. It operates at a 2400 MHz game clock and 2970 MHz boost clock, providing 48.7 TFLOPS of single-precision FP32 compute performance.
Power requirements include a 304 W TBP and a recommended 750 W power supply. The standard RX 9070 reduces specifications to 56 Compute Units (3584 Stream Processors), 56 Ray Accelerators, and 112 AI Accelerators. Clock speeds decrease to 2070 MHz game clock and 2540 MHz boost clock, with correspondingly lower power requirements of 220 W TBP and a recommended 650 W power supply. Since both SKUs use the same Navi 48 die, the separation between them is likely better binning for the XT version, and lower bins end up for the non-XT version. Both models support HDMI 2.1b and DisplayPort 2.1a UHBR13.5 outputs. AMD has confirmed the cards will launch exclusively through board partners with no reference designs planned and that the official unveiling will be in March. Earlier rumors have suggested a $699 price tag for the Radeon RX 9070 XT SKU, putting its expected price/performance near NVIDIA's GeForce RTX 5070 Ti. AMD notes that 85% of gamers buy cards below $700, which the RDNA 4 series will focus on.
