The AMD Radeon RX 9070 XT and NVIDIA GeForce RTX 4080 Super are both high-performance GPUs, but they have different power consumption profiles and performance characteristics.
Power Consumption
- RX 9070 XT: This GPU has a total board power (TBP) of 304 watts, which is slightly lower than the RTX 4080 Super's 320 watts[1][3]. However, some benchmarks have shown that the RX 9070 XT could reach up to 329 watts for top-end boards[7]. The recommended power supply for the RX 9070 XT is 750 watts[1].
- RTX 4080 Super: With a TBP of 320 watts, it is marginally more power-hungry than the RX 9070 XT. The RTX 4080 Super typically requires a robust power supply to handle its power demands, often recommended to be at least 650 watts or more, depending on the system configuration.
Performance Comparison
- RX 9070 XT: This GPU 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[1]. In some benchmarks, such as 3DMark, the RX 9070 XT has shown performance slightly surpassing the RTX 4080 Super by a small margin[6].
- RTX 4080 Super: This NVIDIA GPU is built with more CUDA cores (10240) and has a higher number of AI accelerators (320), but fewer Ray Accelerators (80) compared to the RX 9070 XT[3]. It operates at a lower boost clock speed of 2550 MHz. Despite its slightly lower clock speeds, the RTX 4080 Super generally offers superior performance in games that heavily utilize ray tracing and AI-enhanced features.
Efficiency and Target Market
- RX 9070 XT: AMD's focus with the RX 9070 series is on the mainstream market, aiming to provide strong performance at a competitive price point. The RX 9070 XT is expected to be priced around $699, positioning it as a rival to NVIDIA's GeForce RTX 5070 Ti rather than the higher-end RTX 4080 Super[1][4].
- RTX 4080 Super: NVIDIA's RTX 4080 Super targets the high-end segment, offering superior performance in applications that leverage advanced features like ray tracing and AI acceleration. It is generally more expensive than the RX 9070 XT and is positioned for users seeking top-tier performance.
In summary, while the RX 9070 XT and RTX 4080 Super have similar power consumption profiles, they cater to different segments of the market. The RX 9070 XT is positioned as a strong mid-range option, whereas the RTX 4080 Super is aimed at the high-end market with superior performance in specific applications.
