AMD Radeon RX 580 2048SP vs NVIDIA GeForce RTX 5050 Comparison

The AMD Radeon RX 580 2048SP and the NVIDIA GeForce RTX 5050 represent two very different eras of GPU design. The RX 580 2048SP is an end-of-life Polaris part from 2018, built on a mature 14 nm process, while the RTX 5050 is an active Blackwell 2.0 product from 2025 on a 5 nm node. The benchmark data shows a decisive performance gap, with the RTX 5050 winning all three head-to-head tests, but the comparison reveals more than just a simple victory—it highlights generational shifts in compute, memory architecture, and feature support.

Where Each One Wins

The benchmark data is unambiguous: the NVIDIA GeForce RTX 5050 wins all three head-to-head tests. In 3DMark Steel Nomad DX12, the RTX 5050 posts 2502 versus 849 for the RX 580 2048SP. The Geekbench OpenCL test shows a similar story, with 90334 for the RTX 5050 and 29668 for the RX 580 2048SP. The Geekbench Vulkan test narrows the gap slightly—89381 versus 38666—but the RTX 5050 still leads by a wide margin.

However, the AMD Radeon RX 580 2048SP does have a niche in its average benchmark score. Its 23061 average surpasses the RTX 5050’s 21035, driven by strong showings in its available tests. The RX 580 2048SP also has a higher percentile rank at 68 versus 66. This suggests that in certain legacy or mixed workloads, the older card can hold its own, even if it loses every direct comparison.

The RTX 5050’s wins are not just about raw numbers; they reflect its modern architecture. With 20 RT cores and 80 tensor cores, it brings features the RX 580 2048SP lacks entirely. The RTX 5050 also benefits from a higher boost clock of 2572 MHz versus 1284 MHz, which translates to better sustained performance in compute-heavy tasks.

Architecture Differences

The architectural gap between these two GPUs is generational. The AMD Radeon RX 580 2048SP is built on GCN 4.0, using the Polaris 20 chip fabricated on a 14 nm process by GlobalFoundries. It packs 5,700 million transistors on a 232 mm² die, giving a transistor density of 24.6M per mm². The NVIDIA GeForce RTX 5050 uses the Blackwell 2.0 architecture with the GB207 chip, produced by TSMC on a 5 nm node. It contains 16,900 million transistors on a smaller 149 mm² die, achieving a much higher density of 113.4M per mm².

This density difference is reflected in the feature sets. The RTX 5050 includes dedicated RT cores (20) and tensor cores (80), enabling ray tracing and AI acceleration—capabilities absent from the RX 580 2048SP. The RX 580 2048SP has more TMUs (128 versus 80) but the same number of ROPs (32). The RTX 5050 compensates with higher clock speeds, boosting to 2572 MHz versus the RX 580 2048SP’s 1284 MHz.

Memory architecture also differs fundamentally. The RX 580 2048SP uses a 256-bit bus with GDDR5, while the RTX 5050 uses a narrower 128-bit bus with faster GDDR6. The RTX 5050’s 320.0 GB/s bandwidth exceeds the RX 580 2048SP’s 224.0 GB/s, despite the narrower bus. The RTX 5050 also doubles the VRAM capacity to 8 GB, which is crucial for modern textures and resolutions.

Specification Differences

The two cards differ in nearly every measurable specification. The RX 580 2048SP has a base clock of 1168 MHz and boost clock of 1284 MHz, while the RTX 5050 runs at 2317 MHz base and 2572 MHz boost. Memory speeds are 1750 MHz (7 Gbps effective) for the RX 580 2048SP versus 2500 MHz (20 Gbps effective) for the RTX 5050.

Shading units favor the RTX 5050 at 2560 versus 2048, but TMUs favor the RX 580 2048SP at 128 versus 80. Both have 32 ROPs. The RTX 5050 has higher pixel rate (82.30 GPixel/s versus 41.09 GPixel/s) and texture rate (205.8 GTexel/s versus 164.4 GTexel/s). FP32 compute is 13.17 TFLOPS for the RTX 5050 versus 5.259 TFLOPS for the RX 580 2048SP.

Power and connectivity also differ. The RX 580 2048SP has a TDP of 150 W with a suggested PSU of 450 W, while the RTX 5050 draws 130 W with a 300 W PSU suggestion. Both use a dual-slot design and 1x 8-pin power connector. The RTX 5050 uses PCIe 5.0 x8, while the RX 580 2048SP uses PCIe 3.0 x16. Display outputs differ: the RX 580 2048SP offers 1x DVI, 1x HDMI 2.0b, and 3x DisplayPort 1.4a, while the RTX 5050 provides 1x HDMI 2.1b and 3x DisplayPort 2.1b.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test delivers the most lopsided result. The NVIDIA GeForce RTX 5050 scores 2502, while the AMD Radeon RX 580 2048SP manages only 849. This is a delta of -66.1% for the RX 580 2048SP, meaning the RTX 5050 is approximately 2.95 times faster. This test likely stresses modern DX12 features that the older GCN architecture handles less efficiently.

The Geekbench OpenCL benchmark shows a similar pattern. The RTX 5050 posts 90334, versus 29668 for the RX 580 2048SP, a delta of -67.2%. This large margin suggests the RTX 5050’s higher compute throughput (13.17 TFLOPS versus 5.259 TFLOPS) translates directly into OpenCL performance gains.

The smallest gap appears in the Geekbench Vulkan test. The RTX 5050 scores 89381, while the RX 580 2048SP achieves 38666, a delta of -56.7%. While still a decisive victory for the RTX 5050, the narrower margin hints that Vulkan perhaps mitigates some architectural disadvantages of the older card.

Beyond these three head-to-head tests, the RTX 5050 has additional benchmark data that the RX 580 2048SP lacks. Passmark results for the RTX 5050 show a G3D score of 17326 and GPU compute score of 9184. DirectX 9, 10, 11, and 12 tests yield scores of 186, 103, 150, and 66 respectively. The RX 580 2048SP has no comparable Passmark entries, limiting direct comparison to the three shared tests.

The Verdict

The data makes a clear case: the NVIDIA GeForce RTX 5050 is the superior performer in every shared benchmark. It wins the 3DMark Steel Nomad DX12 test by 66.1%, the Geekbench OpenCL test by 67.2%, and the Geekbench Vulkan test by 56.7%. For any user prioritizing modern gaming or compute workloads, the RTX 5050 is the obvious choice based on these results.

However, the AMD Radeon RX 580 2048SP should not be dismissed outright. Its average benchmark score of 23061 is higher than the RTX 5050’s 21035, and it ranks at the 68th percentile versus 66th. This suggests that in a broader range of tests—potentially including older APIs or less demanding workloads—the RX 580 2048SP can still perform respectably. Its 256-bit memory bus and higher TMU count may benefit certain legacy applications.

The RTX 5050’s advantages extend beyond raw scores. It offers 8 GB of VRAM versus 4 GB, which is increasingly important for modern game textures. It supports DirectX 12 Ultimate and Vulkan 1.4, enabling features like ray tracing and mesh shaders. It also consumes less power (130 W versus 150 W) and requires a smaller PSU (300 W versus 450 W), making it a more efficient choice for system builders.

For users with older systems or specific legacy software needs, the RX 580 2048SP remains a viable if dated option. Its higher average score and percentile rank indicate it still has utility in certain contexts. But for anyone buying a new GPU today, the RTX 5050’s decisive wins in every head-to-head test, combined with its modern feature set and lower power draw, make it the data-driven recommendation. The RTX 5050 also carries a launch MSRP of 249 USD, which contextualizes its position in the market.
