AMD Radeon RX 580 2048SP vs AMD Radeon RX 9070 Comparison

The AMD Radeon RX 9070 is a generational leap over the AMD Radeon RX 580 2048SP, decisively winning every benchmark in the head-to-head comparison. The RX 580 2048SP, an end-of-life product from 2018, simply cannot compete with the modern RDNA 4.0 architecture, resulting in performance gaps that range from substantial to monumental.

Head-to-Head Benchmarks

The most striking disparity emerges in the 3DMark Steel Nomad DX12 test, a demanding modern workload. Here, the RX 9070 scores 6290, while the RX 580 2048SP manages only 849. This represents a 640.9% advantage for the newer card, a gap so large it indicates the RX 580 is not merely slower but is operating in a different performance class entirely.

In compute-oriented tasks, the RX 9070 continues its dominance. The Geekbench OpenCL benchmark shows the RX 9070 achieving a score of 131539 against the RX 580 2048SP's 29668. This 343.4% difference highlights the massive increase in raw computational throughput, driven by the newer architecture's far higher FP32 performance of 36.13 TFLOPS versus 5.259 TFLOPS.

The closest contest, though still a clear victory, occurs in the Geekbench Vulkan test. The RX 9070 scores 58705, which is 51.8% higher than the RX 580 2048SP's 38666. While this is the smallest relative gap of the three benchmarks, it still demonstrates a significant performance advantage that would be immediately noticeable in any Vulkan-based game or application. The data shows the RX 9070 wins all three head-to-head benchmarks, leaving the RX 580 2048SP with zero wins.

The Verdict

The verdict is unequivocal based on benchmark results. The AMD Radeon RX 9070 is the superior graphics card for virtually any use case. Its average benchmark score of 23877 dwarfs the RX 580 2048SP's 23061, but this aggregate figure undersells the true chasm between them. The head-to-head data reveals that the RX 9070 is between 51.8% and 640.9% faster across different workloads, making it the clear choice for anyone building a new system or upgrading from the older Polaris card.

The AMD Radeon RX 580 2048SP should only be considered for legacy systems or specific scenarios where its older feature set and lower power draw are acceptable trade-offs. Its 150 W TDP is lower than the RX 9070's 220 W, and it uses a single 8-pin power connector instead of two. However, the performance penalty is too severe to recommend it as a primary choice for modern gaming or content creation. The RX 9070's active production status and support for newer APIs like DirectX 12 Ultimate (12_2) and Vulkan 1.4, compared to the RX 580's DirectX 12 (12_0) and Vulkan 1.3, solidify its position as the forward-looking option.

Architecture Differences

The architectural chasm between these two GPUs is immense. The RX 9070 is built on the RDNA 4.0 architecture, manufactured on a 4 nm process at TSMC. This is a massive leap from the RX 580 2048SP's GCN 4.0 architecture, which uses a 14 nm process at GlobalFoundries.

This process and architecture change results in a dramatic difference in transistor density. The RX 9070 packs 53,900 million transistors onto a 357 mm² die, achieving a density of 151.0M / mm². In contrast, the RX 580 2048SP has just 5,700 million transistors on a 232 mm² die, with a density of only 24.6M / mm². The newer card is not only more advanced but also more efficiently packed.

A key functional difference is the inclusion of 56 ray tracing cores in the RX 9070, a feature entirely absent from the RX 580 2048SP which has no RT cores. This enables hardware-accelerated ray tracing on the RX 9070. The RX 9070 also supports a newer PCIe interface (PCIe 5.0 x16) compared to the RX 580's PCIe 3.0 x16, allowing for higher bandwidth communication with the CPU.

Specification Differences

The specifications reveal a comprehensive upgrade for the RX 9070 across every major category. The most critical difference is memory configuration: the RX 9070 comes with 16 GB of GDDR6 memory on a 256-bit bus, delivering a bandwidth of 644.6 GB/s. The RX 580 2048SP has only 4 GB of GDDR5 memory, also on a 256-bit bus, but with a much lower bandwidth of 224.0 GB/s. This 16 GB versus 4 GB capacity difference is crucial for modern high-resolution textures and workloads.

The compute resources are also substantially different. The RX 9070 features 3584 shading units, 224 texture mapping units (TMUs), and 128 render output units (ROPs). The RX 580 2048SP has 2048 shading units, 128 TMUs, and only 32 ROPs. This lower ROP count in the RX 580 is a significant bottleneck, particularly at high resolutions, and contributes to its poor performance in the 3DMark test.

Clock speeds and power characteristics also favor the newer card. The RX 9070 has a base clock of 1330 MHz and a boost clock of 2520 MHz, while the RX 580 2048SP operates at 1168 MHz base and 1284 MHz boost. The RX 9070's TDP is 220 W, requiring a 550 W suggested PSU and two 8-pin connectors, whereas the RX 580 2048SP has a 150 W TDP, a 450 W suggested PSU, and a single 8-pin connector. Finally, the RX 9070 supports modern display outputs with 1x HDMI 2.1b and 3x DisplayPort 2.1a, while the RX 580 2048SP offers an older 1x DVI, 1x HDMI 2.0b, and 3x DisplayPort 1.4a.

Where Each One Wins

The AMD Radeon RX 9070 wins in every benchmark category measured. It is the definitive choice for any task that demands high performance, from modern DirectX 12 gaming to compute-intensive applications like OpenCL workloads. Its 16 GB of memory and support for DirectX 12 Ultimate make it suitable for future titles and high-resolution textures. The inclusion of ray tracing cores and a PCIe 5.0 interface further solidify its position as the card for new, high-end systems.

The AMD Radeon RX 580 2048SP has no benchmark wins, but its data suggests a few niche scenarios. Its lower 150 W TDP and single 8-pin connector make it easier to install in older or lower-wattage systems without a PSU upgrade. Its support for Vulkan 1.3 and DirectX 12 (12_0) means it can still run modern games, though with significantly lower performance. It could serve as a basic display adapter or for light, older titles where its 4 GB of memory is not a limiting factor. However, for any serious gaming or productivity work, the RX 9070 is the only logical choice based on the data.
