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

AMD Radeon RX 6550M and NVIDIA GeForce RTX 4070 Ti occupy opposite ends of the mobile and desktop GPU spectrum, and the benchmark data reflects a predictable but stark divide. The RX 6550M is a low-power integrated-class part for thin laptops, while the RTX 4070 Ti is a high-end desktop card that was already end-of-life by the time its successor arrived. Across the two shared benchmark tests, the RTX 4070 Ti wins decisively in both, with the RX 6550M trailing by roughly three-quarters of the performance in each case. The data also shows that despite the massive gap in raw compute, both cards sit within a single percentile point of each other in the global GPU ranking, which is an artifact of how the averaging works rather than an indication of comparable real-world capability.

Head-to-Head Benchmarks

The only two benchmark results shared between these GPUs are Geekbench OpenCL and Geekbench Vulkan, and the NVIDIA card dominates both. In Geekbench OpenCL, the RTX 4070 Ti scores 176,953 against the RX 6550M's 42,536, a delta of -76% for the AMD part. That is not a marginal lead; it is a 4.16x advantage in raw compute throughput. In Geekbench Vulkan, the pattern repeats: the RTX 4070 Ti posts 213,808 versus the RX 6550M's 50,867, again a -76.2% delta. The NVIDIA card is 4.2x faster in Vulkan, which is even slightly larger than its OpenCL lead.

What these deltas mean in practice is that the RX 6550M is not competitive with the RTX 4070 Ti in any compute-heavy workload that uses these APIs. The smaller card's average benchmark score across all tests is 46,702, while the RTX 4070 Ti's average is 44,795 — which is lower than the AMD part's average. This inversion happens because the RTX 4070 Ti's average includes several Passmark tests with very low scores (e.g., 116 in DirectX 12, 187 in DirectX 10), which drag down its mean. The head-to-head deltas are the more honest comparison: the RTX 4070 Ti wins both tests by over 75%.

There is no benchmark in the data where the RX 6550M wins outright. The wins tally is 0 for the AMD card and 2 for the NVIDIA card. Even the RX 6550M's strongest result — its Geekbench Vulkan score of 50,867 — is only 23.8% of the RTX 4070 Ti's Vulkan score. The RTX 4070 Ti also has a much broader benchmark portfolio, with 10 recorded results spanning 3DMark, Passmark, and Geekbench, while the RX 6550M has only the two Geekbench entries. That breadth matters: the RTX 4070 Ti's Passmark G3D score of 31,624 and GPU compute score of 18,396 are not directly comparable to anything the RX 6550M offers, but they confirm the NVIDIA card's strength in rasterization and compute.

Architecture Differences

The RX 6550M is built on AMD's RDNA 2.0 architecture, using the Navi 24 chip on a 6 nm TSMC process. It packs 5,400 million transistors on a 107 mm² die, giving a transistor density of 50.5 million per square millimeter. The RTX 4070 Ti uses NVIDIA's Ada Lovelace architecture with the AD104 chip on a 5 nm TSMC process. It has 35,800 million transistors on a 294 mm² die, for a density of 121.8 million per square millimeter. The NVIDIA chip is 6.6x larger in transistor count and 2.7x larger in die area, with more than double the transistor density.

The memory subsystems are entirely different. The RX 6550M has 4 GB of GDDR6 on a 64-bit bus, yielding 144.0 GB/s of bandwidth. The RTX 4070 Ti has 12 GB of GDDR6X on a 192-bit bus, for 504.2 GB/s — 3.5x the bandwidth. The RTX 4070 Ti also has a much wider compute configuration: 7,680 shading units, 240 texture mapping units, and 80 ROPs, versus the RX 6550M's 1,024 shaders, 64 TMUs, and 32 ROPs. Ray tracing hardware differs too: the NVIDIA card has 60 RT cores and 240 tensor cores, while the AMD card has 16 RT cores and no tensor cores.

Clock speeds tell a different story. The RX 6550M has a higher boost clock at 2,840 MHz versus the RTX 4070 Ti's 2,610 MHz, and a base clock of 2,000 MHz versus 2,310 MHz. The AMD card also has a "game" clock of 2,560 MHz, a concept the NVIDIA card does not report. But raw clocks do not compensate for the 7.5x difference in shading units. The RTX 4070 Ti delivers 40.09 TFLOPS of FP32 performance against the RX 6550M's 5.816 TFLOPS — a 6.9x gap. FP16 performance is even more lopsided: the NVIDIA card maintains 40.09 TFLOPS (1:1 ratio), while the AMD card drops to 11.63 TFLOPS (2:1 ratio).

Power and physical design are also polar opposites. The RX 6550M is an integrated graphics package (IGP) with no power connectors and an 80 W TDP. The RTX 4070 Ti is a dual-slot card measuring 285 mm long, 112 mm tall, and 42 mm wide, with a 285 W TDP and a single 16-pin connector, plus a recommended 600 W power supply. The AMD part uses PCIe 4.0 x4, while the NVIDIA card uses PCIe 4.0 x16. Display outputs differ as well: the RX 6550M is "portable device dependent," while the RTX 4070 Ti offers 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 4070 Ti is the far more powerful GPU, and the head-to-head benchmarks show a 76% to 76.2% performance deficit for the AMD Radeon RX 6550M. The RTX 4070 Ti has 7.5x the shading units, 6.9x the FP32 throughput, and 3.5x the memory bandwidth. It also has a full suite of tensor cores and more RT cores, making it suitable for AI workloads and heavier ray tracing. The RX 6550M's only advantages are a lower TDP (80 W vs 285 W), a higher boost clock (2,840 MHz vs 2,610 MHz), and its integrated form factor, which requires no power connector.

However, the global percentile rankings tell a curious story: the RX 6550M sits at the 85th percentile of all GPUs, while the RTX 4070 Ti sits at the 84th. This is a statistical quirk of the averaging method — the RTX 4070 Ti's Passmark DirectX scores (116 to 352) are anomalously low and pull its average down. Direct comparisons are the only reliable metric here, and they favor the NVIDIA card overwhelmingly. The RTX 4070 Ti was launched at 799 USD as its launch MSRP, and it holds the performance crown in every shared test.

For a user deciding between the two, the choice is really about platform, not performance. The RX 6550M is a mobile-only IGP that trades raw power for portability and efficiency. The RTX 4070 Ti is a desktop card that demands a dual-slot chassis, a 600 W PSU, and a PCIe 4.0 x16 slot. If the requirement is maximum compute or gaming performance, the RTX 4070 Ti is the only option that makes sense. If the requirement is a low-power integrated solution for a laptop, the RX 6550M is the only option that exists.

Where Each One Wins

The RTX 4070 Ti wins in every measured category that matters for performance. In Geekbench OpenCL, it is 4.16x faster. In Geekbench Vulkan, it is 4.2x faster. It has a substantially higher pixel rate (208.8 GPixel/s vs 90.88 GPixel/s) and texture rate (626.4 GTexel/s vs 181.8 GTexel/s). Its FP16 performance is 40.09 TFLOPS at a 1:1 ratio, meaning no rate penalty for half-precision work, whereas the RX 6550M only achieves 11.63 TFLOPS at a 2:1 ratio. The RTX 4070 Ti also has 240 tensor cores, enabling dedicated AI acceleration that the RX 6550M cannot offer at all.

The RX 6550M wins only in efficiency and form factor. Its 80 W TDP is 28% of the RTX 4070 Ti's 285 W draw. It is an IGP with no power connector, which means it can be integrated into thin, portable devices without external power. Its boost clock of 2,840 MHz is higher than the RTX 4070 Ti's 2,610 MHz, and its game clock of 2,560 MHz provides a defined sustained frequency. The RX 6550M also has a higher average benchmark score (46,702 vs 44,795), but as noted, this is an artifact of the RTX 4070 Ti's weak Passmark DirectX results and does not reflect real-world performance.

In practical terms, the RTX 4070 Ti is for desktop builders who need high-end rasterization, ray tracing, and compute throughput. The RX 6550M is for laptop manufacturers who need a capable integrated GPU that sips power. There is no overlap in use cases, and the benchmark data reinforces that separation: the NVIDIA card dominates where performance is measured, while the AMD card's only wins are in power efficiency and physical integration.
