VideoCardz has obtained the specifications for the AMD Radeon RX 9070 series, which are believed to be the final configurations for the upcoming RDNA 4 GPUs. The lineup includes two models based on the Navi 48 GPU, which houses 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 feature the same memory configurations: 16 GB of GDDR6 memory running at 20 Gbps across a 256-bit bus, providing 640 GB/s bandwidth. Each card is equipped with 64 MB of 3rd Generation Infinity Cache and supports PCIe 5.0 x16 interface standards.
The RX 9070 XT boasts 64 RDNA 4 Compute Units, totaling 4096 Stream Processors, 64 Ray Accelerators, and 128 AI Accelerators. It operates at a 2400 MHz game clock and 2970 MHz boost clock, delivering 48.7 TFLOPS of single-precision FP32 compute performance. Power requirements for the RX 9070 XT include a 304 W TBP and a recommended 750 W power supply.
The standard RX 9070 model features 56 Compute Units (3584 Stream Processors), 56 Ray Accelerators, and 112 AI Accelerators. Clock speeds are slightly lower at 2070 MHz game clock and 2540 MHz boost clock, with power requirements of 220 W TBP and a recommended 650 W power supply.
Both models support HDMI 2.1b and DisplayPort 2.1a UHBR13.5 outputs. AMD has confirmed that the cards will be launched exclusively through board partners, with no reference designs planned, and the official unveiling is set for March. Rumors suggest a $699 price tag for the Radeon RX 9070 XT, positioning it in a similar price/performance range as NVIDIA's GeForce RTX 5070 Ti. AMD aims to target 85% of gamers who purchase cards below $700 with the RDNA 4 series.
