AMD Radeon RX Vega M GH vs NVIDIA T550 Mobile Comparison

Head-to-Head Benchmarks

The two benchmarks recorded in the database split the wins evenly, but the magnitude of the victories tells a compelling story. In Geekbench OpenCL, the NVIDIA T550 Mobile posts a score of 35,521 against the AMD Radeon RX Vega M GH's 27,125. That is a 31% advantage for the NVIDIA part, a substantial gap that suggests a fundamental difference in compute throughput for this workload. The OpenCL result is the decisive benchmark here, as the delta is far outside the noise range seen in the nearest rival comparisons.

The Vulkan test flips the result, but narrowly. The AMD Radeon RX Vega M GH scores 31,268, while the NVIDIA T550 Mobile trails at 30,801, a margin of only 1.5%. This is a much tighter race, and the delta is small enough that it could be attributed to driver optimizations or workload-specific scheduling rather than a clear architectural superiority. Still, a win is a win, and the AMD part takes the Vulkan crown by a slim edge.

Looking at the broader context, the NVIDIA T550 Mobile's average benchmark score of 33,161 places it in the 77th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 3050 Mobile at 33,170 (0% delta), the AMD Radeon Pro 570 at 33,207 (-0.1%), the NVIDIA P104-100 at 32,982 (0.5%), and the NVIDIA T600 Mobile at 32,849 (1%). The T550 Mobile is essentially neck-and-neck with the RTX 3050 Mobile, which is notable given the latter's higher tier in the mobile lineup. The AMD Radeon RX Vega M GH, by contrast, averages 29,197 overall, sitting in the 74th percentile. Its nearest rivals are the AMD FirePro W8000 at 29,211 (0% delta), Intel Arc A370M at 29,175 (0.1%), AMD Radeon RX 470 at 28,996 (0.7%), and AMD Radeon RX 6800M at 28,874 (1.1%). The Vega M GH is clustered with mid-range desktop and mobile parts from a few generations back.

The head-to-head average scores show the T550 Mobile leading by roughly 13.5% (33,161 vs 29,197), but the per-test breakdown reveals that this lead is entirely driven by the OpenCL result. The Vulkan test shows the AMD part ahead, which complicates any single-number summary. The data suggests that the NVIDIA GPU is the stronger compute performer in OpenCL, while the AMD GPU holds a slight edge in Vulkan graphics workloads.

Where Each One Wins

The NVIDIA T550 Mobile wins decisively in OpenCL, which is often used for general-purpose GPU compute, including tasks like physics simulations, image processing, and some machine learning inference. The 31% delta in this test indicates that the T550 Mobile's Turing architecture, with its 1,024 shading units and 6.820 TFLOPS of FP16 throughput (2:1 ratio), is well-suited to parallel compute workloads that scale with raw shader count and memory bandwidth efficiency. The T550 Mobile's FP32 performance of 3.410 TFLOPS is paired with a memory bandwidth of 96.00 GB/s, which, while modest, appears sufficient for this particular benchmark.

The AMD Radeon RX Vega M GH wins in Vulkan, a low-overhead graphics API. Its 1,536 shading units and 3.656 TFLOPS of FP32 compute provide a solid foundation for graphics rendering, and the 204.8 GB/s memory bandwidth from HBM2 is a significant asset. The Vulkan result suggests that the Vega M GH can feed its shaders more effectively in graphics-heavy scenarios, even if its compute efficiency in OpenCL lags. The 1.5% win is narrow, but it signals that the AMD part is not outclassed in real-time rendering workloads.

For users prioritizing compute acceleration, the T550 Mobile is the clear choice based on the OpenCL data. For those focused on Vulkan-based games or applications, the Vega M GH has a slight edge. The T550 Mobile's higher average score (33,161 vs 29,197) and better percentile ranking (77th vs 74th) indicate that it is the more consistent performer across the two tests, but the AMD part's Vulkan win should not be dismissed.

Architecture Differences

The two GPUs come from different architectural lineages. The NVIDIA T550 Mobile uses the TU117 chip based on the Turing architecture, fabricated on a 12 nm process at TSMC. It integrates 4,700 million transistors on a 200 mm² die, yielding a transistor density of 23.5M per mm². The AMD Radeon RX Vega M GH uses the Polaris 22 chip based on GCN 4.0, built on a 14 nm process at GlobalFoundries. It packs 5,000 million transistors into a 208 mm² die, with a slightly higher transistor density of 24.0M per mm². The AMD chip is marginally larger and denser, but the NVIDIA chip uses a more modern process node.

Memory configurations differ sharply. The T550 Mobile uses 4 GB of GDDR6 on a 64-bit bus, delivering 96.00 GB/s of bandwidth. The Vega M GH uses 4 GB of HBM2 on a 1024-bit bus, delivering 204.8 GB/s. That is more than double the bandwidth for the AMD part, which explains its Vulkan advantage in memory-intensive scenes. The T550 Mobile's memory clock is listed as 1500 MHz (12 Gbps effective), while the Vega M GH's memory runs at 800 MHz (1600 Mbps effective); the AMD part compensates for lower clock speed with a much wider bus.

Compute resources are also distributed differently. The T550 Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs, with a pixel rate of 53.28 GPixel/s and a texture rate of 106.6 GTexel/s. The Vega M GH has 1,536 shading units, 96 TMUs, and 64 ROPs, with a pixel rate of 76.16 GPixel/s and a texture rate of 114.2 GTexel/s. The AMD part has 50% more shading units and double the ROPs, which should theoretically give it a rasterization advantage. However, the NVIDIA part's FP16 throughput of 6.820 TFLOPS (2:1) is nearly double its FP32 rate, while the AMD part's FP16 is 3.656 TFLOPS (1:1), meaning the T550 Mobile has a significant edge in mixed-precision compute.

Power and interface also differ. The T550 Mobile has a TDP of 23 W and uses a PCIe 3.0 x16 bus interface. The Vega M GH has a TDP of 100 W and uses an IGP bus interface, which is typical for a chip embedded on a processor package. The NVIDIA part is far more power-efficient, which is relevant for thin-and-light laptops, while the AMD part's higher power budget likely contributes to its higher rasterization rates.

The Verdict

The data points to a clear split based on workload. For compute-heavy OpenCL tasks, the NVIDIA T550 Mobile is the superior choice, delivering a 31% higher score than the AMD Radeon RX Vega M GH. Its FP16 throughput of 6.820 TFLOPS (2:1) is nearly double its FP32 rate, making it a strong candidate for mixed-precision compute workloads. The T550 Mobile also has a higher average benchmark score (33,161 vs 29,197) and a better percentile ranking (77th vs 74th), indicating that it is the more balanced performer overall.

For Vulkan-based graphics, the AMD Radeon RX Vega M GH takes a narrow 1.5% lead, likely due to its 204.8 GB/s memory bandwidth and higher shader count. The Vega M GH's 1,536 shading units and 64 ROPs give it a theoretical rasterization edge, and the HBM2 memory provides ample bandwidth for texture-heavy scenes. However, the 100 W TDP is a significant drawback for mobile use, especially compared to the T550 Mobile's 23 W TDP.

The choice depends on the intended use case. Users who prioritize compute acceleration, power efficiency, and overall consistency should favor the NVIDIA T550 Mobile. Users who need maximum memory bandwidth and Vulkan graphics performance, and who can tolerate a higher power draw, may prefer the AMD Radeon RX Vega M GH. The recorded data does not support a single winner; it supports a workload-specific verdict. The NVIDIA part wins the compute race by a wide margin, while the AMD part wins the graphics race by a hair.
