AMD Radeon 550 vs NVIDIA GeForce RTX 5080 SUPER Comparison

The GeForce RTX 5080 SUPER and the Radeon 550 represent two extremes of the GPU market, separated by nearly a decade of architectural evolution and a massive gulf in raw performance. The data shows that the RTX 5080 SUPER is a high-end Blackwell 2.0 part designed for modern, demanding workloads, while the Radeon 550 is an entry-level GCN 4.0 chip from 2017 aimed at basic display output and legacy applications. Their benchmark scores, however, tell a more nuanced story about how different testing methodologies can position these cards relative to unexpected rivals.

Head-to-Head Benchmarks

The most striking discrepancy in the data is the absence of a shared benchmark between the two cards. The RTX 5080 SUPER has a single recorded score in the 3DMark Steel Nomad DX12 test, achieving 3,075 points. The Radeon 550, conversely, has no 3DMark Steel Nomad result, instead being characterized by a suite of Geekbench and Passmark tests where it scores 10,339 in Geekbench OpenCL and 11,257 in Geekbench Vulkan. This makes a direct apples-to-apples comparison impossible, forcing an analysis based on their respective percentile rankings and nearest rival relationships.

Looking at the overall standings, the RTX 5080 SUPER sits at the 19th percentile of all GPUs, while the Radeon 550 is at the 18th percentile. This near-identical percentile placement is misleading, as it is a product of the benchmark databases each card is tested in. The RTX 5080 SUPER's average benchmark score of 3,075 is actually 9.8% higher than the Radeon 550's average of 2,801, a difference of 274 points. This suggests that in a hypothetical direct comparison, the newer card would hold a clear, though not overwhelming, performance advantage.

The rivalry data further complicates the picture. The RTX 5080 SUPER is 2.8% behind the NVIDIA Quadro P1000 (3,163 vs. 3,075) and 3.4% behind the Intel Arc Pro B60 (3,182 vs. 3,075), while being 3.1% ahead of the GeForce 820A and 3.6% ahead of the GeForce GTX 860M. This places it in a tight cluster of professional and legacy mobile parts. Meanwhile, the Radeon 550's closest rival is the NVIDIA GeForce RTX 3060 Ti GDDR6X, with the Radeon 550 edging out a 0.2% lead (2,801 vs. 2,795). It also leads the GeForce 820M by 0.6% and the Intel UHD Graphics 610 by 1.8%, while trailing the RTX 4010 by 3.2%. These rivalries suggest that the Radeon 550's aggregate score is being bolstered by its strong Geekbench results, which may not translate to equivalent gaming performance.

When examining specific workload indicators, the Radeon 550's Passmark scores reveal its limitations: it scores 7 in DirectX 10, 15 in DirectX 11, 14 in DirectX 12, and 35 in DirectX 9. Its best result is in the 2D test with 479 points, and its G3D score is 2,124. These figures are extremely low for any contemporary gaming context. The RTX 5080 SUPER, with its single DX12-focused benchmark, is clearly not being tested in the same legacy conditions, but its architectural capabilities, as detailed in the next section, point to a card that would dominate in any modern API.

Architecture Differences

The architectural chasm between these two GPUs is vast. The RTX 5080 SUPER is built on TSMC's 5 nm process node, housing 45,600 million transistors on a 378 mm² die, resulting in a transistor density of 120.6M per mm². In contrast, the Radeon 550 is fabricated on GlobalFoundries' 14 nm node, with just 2,200 million transistors on a 103 mm² die, giving it a density of 21.4M per mm². The RTX 5080 SUPER's transistor count is over twenty times higher, showcasing the sheer scale of the newer design.

The core configurations are equally disparate. The RTX 5080 SUPER features 10,752 shading units, 336 TMUs, and 112 ROPs, along with dedicated hardware comprising 84 RT cores and 336 tensor cores. The Radeon 550, by contrast, has only 512 shading units, 32 TMUs, and 16 ROPs, with no dedicated RT or tensor cores at all. This means the RTX 5080 SUPER is equipped for hardware-accelerated ray tracing and AI-driven features, while the Radeon 550 lacks both, relying purely on traditional rasterization.

Clock speeds and memory subsystems also differ dramatically. The RTX 5080 SUPER operates at a base clock of 2295 MHz and a boost clock of 2617 MHz, paired with 24 GB of GDDR7 memory on a 256-bit bus, delivering 1.02 TB/s of bandwidth. The Radeon 550 runs at a base clock of 1100 MHz and a boost of 1183 MHz, with only 2 GB of GDDR5 memory on a 64-bit bus, yielding a mere 56.00 GB/s of bandwidth. The RTX 5080 SUPER's memory bandwidth is nearly twenty times higher, a critical factor for high-resolution textures and data-intensive compute tasks.

The compute throughput numbers quantify the performance gap. The RTX 5080 SUPER delivers 56.28 TFLOPS of FP32 performance and an identical 56.28 TFLOPS for FP16 (1:1 ratio), while the Radeon 550 manages only 1,211.4 GFLOPS (1.21 TFLOPS) in both FP32 and FP16. The pixel and texture rates follow suit: the RTX 5080 SUPER achieves 293.1 GPixel/s and 879.3 GTexel/s, versus the Radeon 550's 18.93 GPixel/s and 37.86 GTexel/s. The RTX 5080 SUPER also supports newer API versions, including DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the Radeon 550 is limited to DirectX 12 (12_0) and Vulkan 1.3.

Where Each One Wins

The RTX 5080 SUPER's advantages are clear across nearly every metric. Its 24 GB of GDDR7 memory and 1.02 TB/s bandwidth make it suitable for 4K gaming, professional 3D rendering, and AI workloads that require large datasets. The presence of 84 RT cores and 336 tensor cores means it is purpose-built for modern games with ray tracing and for applications leveraging DLSS or other AI-accelerated features. Its high FP32 and FP16 throughput of 56.28 TFLOPS positions it as a compute powerhouse for scientific simulations and video editing. The card's support for PCIe 5.0 x16 and its 304 mm length indicate it is designed for a high-end desktop system with a robust power supply.

The Radeon 550, conversely, wins in scenarios where its low power draw and physical size are paramount. With a TDP of just 50 W and no power connectors required, it can run in systems with a 250 W suggested PSU, making it ideal for basic office PCs, legacy machines, or as a display output card. Its 145 mm length allows it to fit into compact cases where the 304 mm RTX 5080 SUPER would not. Its Geekbench scores of 10,339 (OpenCL) and 11,257 (Vulkan) suggest it can handle light compute tasks and older DirectX 9/10 titles, as indicated by its Passmark score of 35 in DirectX 9, which is its highest API-specific result. The Radeon 550's 2 GB of memory and 56 GB/s bandwidth are adequate for 1080p gaming at low settings in games from its 2017 era, but it is not competitive for modern releases.

In terms of ecosystem, the RTX 5080 SUPER's support for DirectX 12 Ultimate and Vulkan 1.4 ensures compatibility with the latest gaming features, while the Radeon 550's older GCN 4.0 architecture and DirectX 12 (12_0) support mean it will struggle with features like mesh shaders or variable rate shading. The RTX 5080 SUPER's 1x HDMI 2.1b and 3x DisplayPort 2.1b outputs support the latest high refresh rate monitors, whereas the Radeon 550's 1x DVI, 1x HDMI 2.0b, and 1x DisplayPort 1.4a are sufficient for older display setups but lack support for the newest bandwidth standards.

The Verdict

The data presents a clear verdict for different use cases. The NVIDIA GeForce RTX 5080 SUPER is the obvious choice for any user requiring high-end gaming, professional content creation, or AI acceleration, provided they have the system to support its 415 W TDP and dual-slot footprint. Its 24 GB of memory, 56.28 TFLOPS of compute, and dedicated RT/tensor cores make it a future-proof investment for demanding applications. Its 19th percentile ranking and proximity to professional GPUs like the Quadro P1000 and Arc Pro B60 reinforce its workstation-level capability.

The AMD Radeon 550, conversely, is strictly a legacy or budget-display card. Its 18th percentile ranking, driven by strong Geekbench numbers, does not translate into practical gaming performance, as evidenced by its low Passmark DirectX 11 and 12 scores of 15 and 14, respectively. Its 50 W power draw and compact size make it perfect for office builds, HTPCs, or as a secondary display adapter where its 2 GB of memory and 56 GB/s bandwidth are adequate. It is not a gaming card by modern standards, and its DirectX 12 (12_0) support limits it to older APIs.

For a user building a new high-performance system, the RTX 5080 SUPER is the only rational choice. For someone needing a low-power, low-cost solution for basic tasks or to revive an older machine, the Radeon 550 serves that niche. There is no overlap in their target markets; choosing between them is a matter of determining whether the system's primary role is heavy lifting or simple utility. The RTX 5080 SUPER is in active production, while the Radeon 550 is end-of-life, signaling the natural progression of the market toward newer architectures.
