Η AMD fully revealed graphics card specifications Radeon RX 9070 and RX 9070 XT, which are based on the new architecture RDNA4 and are manufactured in 4nm
Both models use the same Navi 48 GPU, with 53,9 billion transistors and core area 357 mm²However, the two cards differ in the number of Compute Units, performance and power consumption, with the RX 9070 XT to bring the full configuration of 64 CU, while the simple version has 56 CU.
Η Radeon RX 9070 XT has 4096 Stream Processors, with timings reaching 2400 MHz (Game Clock) and up 2970 MHz (Boost Clock). AMD estimates that the single-precision floating-point (FP32) processing power reaches 48,7 TFLOPS.
On the other hand, the RX 9070 comes with 3584 Stream Processors, lower timings (2070 MHz Game Clock, 2520 MHz Boost Clock) and reduced computing power to 36,1 TFLOPS. Both cards feature 16GB GDDR6 memory with a speed of 20 Gbps and 256-bit bus, delivering 640 GB/s bandwidth.
An important differentiation concerns energy consumption, as the RX 9070 XT has a total TDP 304W, while the basic version RX 9070 amounts to 220wAMD recommends a 750W power supply for the XT and a 650W for the regular version. Also impressive is the fact that both models come with 64MB 3rd Gen Infinity Cache for performance optimization. In addition, it is supported PCIe 5.0 x16 for high-speed communication with the motherboard.
It is worth noting that AMD will not be releasing reference models for this series, as the cards will be made available exclusively through partners (AIB-only). The absence of official reference designs may affect the market, leaving implementations exclusively to manufacturing companies such as ASUS, MSI, Gigabyte and Sapphire.
With the release expected next month, the RX 9070 series is aimed at the upper mid-range, offering competitive performance against NVIDIA's new offerings.
