AMD Radeon RX 6550M vs NVIDIA GeForce RTX 5080 Comparison

The NVIDIA GeForce RTX 5080 and AMD Radeon RX 6550M occupy opposite ends of the graphics spectrum. The RTX 5080 is a desktop flagship built on the Blackwell 2.0 architecture, while the RX 6550M is a mobile RDNA 2.0 part designed for laptops. Benchmark data shows the RTX 5080 leads by a massive 454.6% in Geekbench OpenCL and 402.2% in Geekbench Vulkan. These are not competing products in any practical sense; they serve entirely different use cases and performance tiers.

The Verdict

The data is unambiguous: the RTX 5080 is the performance king, with an average benchmark score of 56,083 compared to the RX 6550M's 46,702. In head-to-head testing, the RTX 5080 wins both available benchmarks, securing 2 wins to 0. Its nearest rivals in the database—the AMD Radeon 8060S (0.6% ahead), RX 6750 GRE 12 GB (0.7% ahead), and Pro W5700X (2.3% ahead)—show it trades blows with top-tier desktop parts, while the RX 9070 GRE sits 2.2% ahead. The RX 6550M, by contrast, is clustered with mobile and workstation parts like the Intel Arc A530M (0.2% behind), RX 5600M (0.2% behind), and RTX A2000 (1.4% behind).

For desktop builders seeking maximum compute performance, the RTX 5080 is the clear choice. Its 87th percentile ranking among all GPUs places it well above the RX 6550M's 85th percentile, despite the latter being a mobile chip. The RX 6550M makes sense only for compact laptops where its 80 W TDP and IGP slot width are mandatory constraints. No user comparing these two should expect the RX 6550M to compete on raw performance; it wins on portability and power efficiency by design.

Architecture Differences

The architectural gap between these GPUs is generational and physical. The RTX 5080 uses the GB203 chip on TSMC's 5 nm process, packing 45,600 million transistors into a 378 mm² die—a transistor density of 120.6M per mm². The RX 6550M uses the Navi 24 chip on TSMC's 6 nm process, with just 5,400 million transistors on a 107 mm² die (50.5M per mm²). That is an 8.4x difference in transistor count and a 3.5x difference in die size.

Core configurations diverge sharply. The RTX 5080 features 10,752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The RX 6550M has 1,024 shading units, 64 TMUs, 32 ROPs, and 16 RT cores, with no tensor cores listed. Memory subsystems are equally disparate: the RTX 5080 has 16 GB of GDDR7 on a 256-bit bus delivering 960.0 GB/s, while the RX 6550M has 4 GB of GDDR6 on a 64-bit bus at 144.0 GB/s. Clock speeds tell a different story—the RX 6550M boosts to 2840 MHz (game clock 2560 MHz) versus the RTX 5080's 2617 MHz boost—but the RTX 5080's massive core count overwhelms that clock advantage.

Feature support is similar on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 uses PCIe 5.0 x16 and a 360 W TDP with a 16-pin connector, while the RX 6550M uses PCIe 4.0 x4 and an 80 W TDP with no power connectors, being an IGP-class mobile part.

Where Each One Wins

The RTX 5080 wins every benchmark where both are tested. In Geekbench OpenCL, it scores 235,901 against the RX 6550M's 42,536—a 454.6% advantage. In Geekbench Vulkan, it scores 255,450 versus 50,867, a 402.2% lead. This is not a contest; the RTX 5080 is designed for high-end desktop gaming, content creation, and compute workloads where raw throughput matters.

The RX 6550M's wins are not in benchmarks but in physical attributes. Its 80 W TDP is a fraction of the RTX 5080's 360 W, making it suitable for thin-and-light laptops where power delivery and cooling are constrained. It is an IGP (integrated graphics processor) with no slot width, no power connectors, and portable-device-dependent display outputs. The RTX 5080 is a dual-slot, 304 mm long, 137 mm tall, 40 mm wide expansion card requiring a 750 W suggested PSU. The RX 6550M also has a higher boost clock (2840 MHz vs 2617 MHz) and a higher game clock (2560 MHz), which matters in power-limited mobile scenarios.

Use-case split: desktop workstations and enthusiast gaming rigs get the RTX 5080; mobile workstations and gaming laptops get the RX 6550M. The RTX 5080's 16 GB GDDR7 memory and 960 GB/s bandwidth handle 4K textures and large datasets; the RX 6550M's 4 GB GDDR6 and 144 GB/s bandwidth are adequate for 1080p gaming on the go.

Head-to-Head Benchmarks

Only two benchmarks cover both GPUs, and the results are lopsided. In Geekbench OpenCL, the RTX 5080 scores 235,901 against the RX 6550M's 42,536. That is a 454.6% delta, meaning the RTX 5080 delivers more than 5.5 times the OpenCL compute performance. This test exercises general-purpose GPU compute, and the RTX 5080's 10,752 shading units and 56.28 TFLOPS FP32 throughput crush the RX 6550M's 1,024 shading units and 5.816 TFLOPS.

The Geekbench Vulkan test shows a slightly smaller but still enormous gap: 255,450 for the RTX 5080 versus 50,867 for the RX 6550M, a 402.2% delta. Vulkan is a low-level graphics API, and the RTX 5080's 84 RT cores and 336 tensor cores provide substantial acceleration for modern rendering workloads. The RX 6550M's 16 RT cores and lack of tensor cores limit its capability in ray-traced and AI-accelerated scenes.

The RTX 5080's average benchmark score of 56,083 places it 20.1% above the RX 6550M's 46,702 average. In terms of percentile ranking, the RTX 5080 sits at 87th percentile versus the RX 6550M's 85th—a narrow gap in percentile terms that masks the massive absolute difference. This is because percentile ranks include all GPUs, many of which are far slower than both.

The RTX 5080's pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s dwarf the RX 6550M's 90.88 GPixel/s and 181.8 GTexel/s. These figures translate directly to fill-rate-bound workloads: high-resolution rendering, heavy post-processing, and texture-heavy scenes all favor the RTX 5080 overwhelmingly. The RX 6550M's higher boost clock (2840 MHz vs 2617 MHz) and game clock (2560 MHz) only partially compensate for its 10.5x fewer shading units.

In the broader context, the RTX 5080's nearest rival is the AMD Radeon 8060S, which is 0.6% ahead in average score. The RX 9070 GRE sits 2.2% ahead, while the RX 6750 GRE 12 GB is 0.7% behind. The RX 6550M's closest competitor is the Intel Arc A530M, just 0.2% behind, followed by the RX 5600M at 0.2% behind. The RTX A2000 is 1.4% behind the RX 6550M, and the RTX 5880 Ada Generation is 1.6% behind. These rival clusters confirm that the RTX 5080 competes in the desktop high-end tier, while the RX 6550M belongs in the mobile mid-range tier.
