AMD Radeon Pro 575X vs NVIDIA T550 Mobile Comparison

The Verdict

The AMD Radeon Pro 575X and NVIDIA T550 Mobile are both end-of-life mobile graphics solutions, but they serve distinctly different workloads based on the recorded benchmark data. The AMD Radeon Pro 575X is the stronger choice for Vulkan-based applications, delivering a 23.1% higher score in Geekbench Vulkan (37919 vs 30801). The NVIDIA T550 Mobile counters with a slight 2.1% edge in Geekbench OpenCL (35521 vs 34773), making it marginally better for OpenCL compute tasks.

The AMD card also holds the higher overall standing in the database, sitting at the 82nd percentile versus the NVIDIA card's 77th percentile. Its average benchmark score of 39116 outpaces the T550 Mobile's 33161 by roughly 18%. However, the T550 Mobile's much lower power envelope, 23 W against 150 W, makes it the practical pick for thin-and-light systems where thermals and battery life matter more than raw throughput.

If your workload leans on Vulkan, the Radeon Pro 575X is the clear winner. If you need OpenCL performance in a low-power package, the T550 Mobile takes it. For users who prioritize the highest average score across all recorded tests, the AMD part wins, but the NVIDIA card's efficiency cannot be ignored. There is no universal winner; the choice depends entirely on the API in use and the power budget available.

A: The Radeon Pro 575X is nearly tied with the AMD Radeon Pro 580X and NVIDIA GeForce MX570 A, both within 1.1% of its average score. The T550 Mobile is essentially level with the NVIDIA GeForce RTX 3050 Mobile (0% delta) and the AMD Radeon Pro 570 (-0.1% delta).

Architecture Differences

The two GPUs come from different architectural generations and foundries. The AMD Radeon Pro 575X uses the Ellesmere chip built on GCN 4.0 architecture, manufactured by GlobalFoundries on a 14 nm process. It packs 5,700 million transistors into a 232 mm² die, yielding a transistor density of 24.6 million per mm². The NVIDIA T550 Mobile uses the TU117 chip based on Turing architecture, fabricated by TSMC on a 12 nm process. It contains 4,700 million transistors on a 200 mm² die, with a density of 23.5 million per mm². The AMD chip is physically larger and denser, while the NVIDIA chip uses a newer process node despite being smaller.

Core configurations differ substantially. The Radeon Pro 575X fields 2048 shading units, 128 texture mapping units, and 32 raster operation pipelines. The T550 Mobile has half the shading units (1024), half the TMUs (64), but the same 32 ROPs. Neither card includes dedicated ray tracing cores or tensor cores, so both are traditional rasterization and compute designs.

API support shows a split: the AMD card reaches DirectX 12 (12_0) and Vulkan 1.3, while the NVIDIA card supports DirectX 12 (12_1) and Vulkan 1.4. OpenGL 4.6 is common to both. The NVIDIA part's higher DirectX feature level and Vulkan version reflect its newer architecture, but the AMD part compensates with a much larger raw compute pipeline.

Specification Differences

Memory subsystems differ sharply. The AMD Radeon Pro 575X uses 4 GB of GDDR5 on a 256-bit bus, delivering 217.0 GB/s of bandwidth. The NVIDIA T550 Mobile also has 4 GB, but it is GDDR6 on a 64-bit bus, yielding only 96.00 GB/s. That is less than half the bandwidth of the AMD card, a significant handicap for memory-heavy workloads.

Clock behavior is another divider. The AMD card lists no base or boost clock in the database, only a memory clock of 1695 MHz (6.8 Gbps effective). The NVIDIA card has a base clock of 1065 MHz and a boost clock of 1665 MHz, with memory at 1500 MHz (12 Gbps effective). The NVIDIA part's boost clock gives it a higher pixel rate of 53.28 GPixel/s versus the AMD card's 35.07 GPixel/s, despite the AMD card's higher texture rate of 140.3 GTexel/s against 106.6 GTexel/s.

Compute throughput also diverges. The AMD card reaches 4.489 TFLOPS FP32 and the same 4.489 TFLOPS FP16 (1:1 ratio). The NVIDIA card delivers 3.410 TFLOPS FP32 but 6.820 TFLOPS FP16 (2:1 ratio), so it crushes the AMD part in half-precision work while trailing in single-precision.

Power and packaging are dramatic differentiators. The AMD Radeon Pro 575X is rated at 150 W, while the NVIDIA T550 Mobile draws only 23 W. Both are IGP-class with no power connectors, and both use PCIe 3.0 x16. Display outputs are listed as portable device dependent for each, and neither has published dimensions. The AMD card launched on 2019-03-17; the NVIDIA card has no recorded release date. The T550 Mobile's predecessor is the Quadro Pascal-M and its successor is the Ampere-MW, while the AMD card lists no predecessor or successor.

Head-to-Head Benchmarks

Two benchmark comparisons are recorded between these cards, and each takes one win.

Geekbench OpenCL goes to the NVIDIA T550 Mobile with 35521 points against 34773 for the AMD Radeon Pro 575X. The delta is 2.1% in favor of NVIDIA. This is a modest margin, and it suggests that in OpenCL compute tasks, the T550 Mobile's Turing architecture and higher boost clock compensate for its narrower memory bus and fewer shading units. The AMD card's larger compute array (2048 shaders) cannot overcome the efficiency of the NVIDIA design in this API.

Geekbench Vulkan flips the result decisively. The AMD Radeon Pro 575X scores 37919, while the T550 Mobile manages 30801. That is a 23.1% lead for AMD. This is the single largest performance gap in the head-to-head data, and it shows that GCN 4.0's Vulkan driver implementation is substantially stronger than Turing's in this specific workload. The AMD card's higher memory bandwidth (217.0 GB/s vs 96.00 GB/s) and greater FP32 throughput (4.489 TFLOPS vs 3.410 TFLOPS) likely contribute to this advantage.

Across both tests, the AMD card's average score of 39116 versus the NVIDIA card's 33161 reinforces the pattern: the Radeon Pro 575X is the faster overall GPU, but the T550 Mobile is not far behind in OpenCL and offers far lower power consumption.

Where Each One Wins

The AMD Radeon Pro 575X wins in Vulkan-heavy environments. Its 23.1% advantage in Geekbench Vulkan makes it the recommended pick for applications built on Vulkan, which includes many modern game engines and compute frameworks. Its higher average benchmark score (39116 vs 33161) and 82nd percentile ranking versus the T550 Mobile's 77th also make it the stronger all-around performer in the database. The AMD card's 217.0 GB/s memory bandwidth and 4.489 TFLOPS FP32 throughput give it a clear edge in bandwidth-sensitive and single-precision compute tasks. It is the choice for users who need maximum performance and are not constrained by power limits.

The NVIDIA T550 Mobile wins in OpenCL workloads, albeit narrowly. Its 2.1% lead in Geekbench OpenCL (35521 vs 34773) makes it the pick for OpenCL compute pipelines where every point counts. More importantly, its 23 W TDP versus 150 W for the AMD card makes it the only rational choice for ultra-portable systems, passively cooled designs, or any chassis with a tight thermal budget. The T550 Mobile also supports a newer DirectX feature level (12_1 vs 12_0) and Vulkan 1.4 versus 1.3, which matters for software that relies on those newer API features. Its FP16 throughput of 6.820 TFLOPS (2:1) is nearly double the AMD card's 4.489 TFLOPS, so half-precision workloads will run faster on the NVIDIA part.

In practical terms, a builder assembling a workstation for Vulkan rendering or general compute should take the Radeon Pro 575X. A builder prioritizing OpenCL compatibility, low power draw, or half-precision math should take the T550 Mobile. The data does not support a single recommendation for all users; it supports two different recommendations for two different use cases.
