AMD Radeon RX 6550M vs NVIDIA GeForce RTX 4070 SUPER Comparison

AMD Radeon RX 6550M and NVIDIA GeForce RTX 4070 SUPER occupy opposite ends of the mobile and desktop GPU spectrum. The RX 6550M is a low-power, integrated-class part built for thin-and-light laptops, while the RTX 4070 SUPER is a high-end desktop board aimed at demanding gaming and compute workloads. The benchmark data confirms a decisive performance gap, but the two GPUs are not competing for the same buyer. This analysis breaks down where each card wins, what the numbers actually show, and which user should consider which product.

Where Each One Wins

The RTX 4070 SUPER wins every single head-to-head benchmark included in the data. In Geekbench OpenCL, it scores 172,795 against the RX 6550M’s 42,536, a delta of -75.4% from the NVIDIA card’s perspective. In Geekbench Vulkan, the RTX 4070 SUPER posts 205,624 versus 50,867, a -75.3% difference. There are no benchmark categories where the AMD part pulls ahead.

However, the RX 6550M wins in a different sense: it is designed for a completely different form factor. The AMD card is an IGP (integrated graphics processor) with a 80 W TDP, no power connectors, and portable-device-dependent display outputs. The RTX 4070 SUPER is a dual-slot, 220 W board requiring a 550 W suggested PSU and a 16-pin power connector. The RX 6550M fits into ultraportable systems where the RTX 4070 SUPER physically cannot go.

The RTX 4070 SUPER also holds the advantage in raw architectural resources. It has 7,168 shading units, 224 TMUs, 80 ROPs, 56 RT cores, and 224 tensor cores. The RX 6550M has 1,024 shading units, 64 TMUs, 32 ROPs, and 16 RT cores, with no tensor cores listed. The NVIDIA card’s 12 GB of GDDR6X memory on a 192-bit bus delivers 504.2 GB/s of bandwidth, versus 4 GB of GDDR6 on a 64-bit bus at 144.0 GB/s for the AMD part.

The Verdict

Pick the RTX 4070 SUPER if you need maximum compute performance in a desktop system. The data shows it is roughly four times faster than the RX 6550M in both OpenCL and Vulkan workloads. It also offers substantially more memory bandwidth and VRAM capacity, which matters for modern games and GPU-accelerated tasks. The RTX 4070 SUPER was launched with a 599 USD MSRP, and its production status is end-of-life, so it is a mature product with established driver support.

Pick the RX 6550M if you are constrained by power and space. It is an active, current product with a 6 nm process and a 80 W TDP, making it suitable for compact laptops where a discrete card is not an option. Its performance is competitive with other low-power parts: the nearest rivals are the Intel Arc A530M at 46,614 average score (0.2% delta), the AMD Radeon RX 5600M at 46,601 (0.2% delta), and the NVIDIA RTX A2000 at 46,043 (1.4% delta). The RX 6550M’s average benchmark score of 46,702 places it in the 85th percentile of all GPUs, which is respectable for its class.

Do not pick the RX 6550M for high-end gaming or heavy compute. The RTX 4070 SUPER’s scores are in a different league, and its 83rd percentile ranking understates its capability because the average includes many lower-end mobile parts. The RX 6550M is a solution for basic 3D acceleration, not a performance part.

Head-to-Head Benchmarks

The two head-to-head results are both Geekbench tests, and both go overwhelmingly to the NVIDIA card. In Geekbench OpenCL, the RTX 4070 SUPER scores 172,795 versus the RX 6550M’s 42,536. That is a 75.4% advantage for NVIDIA, meaning the RTX 4070 SUPER delivers roughly 4.06 times the OpenCL performance of the AMD part. In Geekbench Vulkan, the gap is nearly identical: 205,624 versus 50,867, a 75.3% delta, or about 4.04 times the performance.

These deltas are consistent across both API tests, which suggests the difference is fundamental rather than workload-specific. The RTX 4070 SUPER’s FP32 throughput is 35.48 TFLOPS versus 5.816 TFLOPS for the RX 6550M, and its texture rate is 554.4 GTexel/s versus 181.8 GTexel/s. The pixel rate gap is also large: 198.0 GPixel/s versus 90.88 GPixel/s.

The RX 6550M’s only comparative strengths are relative to other low-power parts, not against the RTX 4070 SUPER. Its Geekbench Vulkan score of 50,867 is higher than its OpenCL score of 42,536, indicating better driver optimization for Vulkan on AMD’s part. But against the NVIDIA card, both scores are dwarfed.

FAQ

Q: Which GPU has a higher average benchmark score?

A: The RX 6550M has a higher average benchmark score of 46,702, versus 43,223 for the RTX 4070 SUPER. This is because the average includes different test suites; the head-to-head tests favor NVIDIA overwhelmingly.

Q: How much faster is the RTX 4070 SUPER in Vulkan?

A: The RTX 4070 SUPER scores 205,624 in Geekbench Vulkan versus 50,867 for the RX 6550M, a 75.3% advantage. That is roughly four times the performance.

Q: Does the RX 6550M have any benchmark wins over the RTX 4070 SUPER?

A: No. In the two head-to-head benchmarks provided (Geekbench OpenCL and Vulkan), the RTX 4070 SUPER wins both. The RX 6550M has zero wins in the head-to-head data.

Q: What is the memory configuration difference?

A: The RX 6550M has 4 GB of GDDR6 on a 64-bit bus with 144.0 GB/s bandwidth. The RTX 4070 SUPER has 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s bandwidth.

Q: Which card is more power-efficient?

A: The RX 6550M has a far lower TDP at 80 W, versus 220 W for the RTX 4070 SUPER. However, the RTX 4070 SUPER delivers far more performance per watt in absolute terms, given its 4x performance advantage.

Q: Are both cards still in production?

A: No. The RX 6550M is listed as Active, while the RTX 4070 SUPER is End-of-life. The RTX 4070 SUPER has a successor (GeForce 50 series), while the RX 6550M does not.

Architecture Differences

The two GPUs come from entirely different architectural generations and design philosophies. The RX 6550M uses AMD’s RDNA 2.0 architecture on a 6 nm TSMC process, with 5,400 million transistors on a 107 mm² die. The RTX 4070 SUPER uses NVIDIA’s Ada Lovelace architecture on a 5 nm TSMC process, with 35,800 million transistors on a 294 mm² die. The transistor density reflects this: the NVIDIA chip packs 121.8M transistors per mm², versus 50.5M for the AMD chip.

The RTX 4070 SUPER has a massive compute advantage in shading units (7,168 versus 1,024), TMUs (224 versus 64), and ROPs (80 versus 32). It also has 56 RT cores versus 16, and 224 tensor cores versus none on the AMD part. This means the NVIDIA card supports dedicated tensor operations for AI workloads, while the AMD card does not.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. However, the RTX 4070 SUPER’s FP16 performance is 35.48 TFLOPS (1:1 ratio with FP32), while the RX 6550M’s FP16 is 11.63 TFLOPS (2:1 ratio). The NVIDIA card’s equal FP16/FP32 throughput is advantageous for compute tasks that use mixed precision.

Specification Differences

The most obvious specification gap is memory. The RX 6550M offers 4 GB of GDDR6 with a 64-bit bus and 144.0 GB/s bandwidth. The RTX 4070 SUPER offers 12 GB of GDDR6X with a 192-bit bus and 504.2 GB/s bandwidth. That is 3x the capacity and 3.5x the bandwidth.

Clock speeds differ as well. The RX 6550M has a base clock of 2000 MHz and a boost of 2840 MHz, with a game clock of 2560 MHz. The RTX 4070 SUPER has a base clock of 1980 MHz and a boost of 2475 MHz, with no game clock listed. Despite lower clocks, the RTX 4070 SUPER achieves far higher throughput due to its vastly larger core count.

Power and physical dimensions are critical differentiators. The RX 6550M is an IGP with 80 W TDP, no power connectors, and no specified dimensions. The RTX 4070 SUPER is a dual-slot card measuring 267 mm x 112 mm x 42 mm, with a 220 W TDP, a single 16-pin power connector, and a recommended 550 W PSU. The bus interface also differs: PCIe 4.0 x4 for the AMD part versus PCIe 4.0 x16 for the NVIDIA card.

Display outputs are another split. The RX 6550M’s outputs are portable-device dependent, meaning they vary by laptop. The RTX 4070 SUPER has fixed outputs: 1x HDMI 2.1 and 3x DisplayPort 1.4a. The release dates are about a year apart: the RX 6550M launched January 3, 2023, and the RTX 4070 SUPER launched January 16, 2024.
