AMD Radeon Pro 5500M vs NVIDIA RTX PRO 6000D Blackwell Max-Q Comparison

The AMD Radeon Pro 5500M and the NVIDIA RTX PRO 6000D Blackwell Max-Q represent two extremes of the GPU spectrum: a 2019 mobile workstation part built on RDNA 1.0 and a 2025 flagship desktop-class accelerator built on Blackwell 2.0. The data shows a generational chasm, but the comparison is complicated by the fact that the two products share almost no common benchmark tests in the database. The Radeon Pro 5500M has a substantial set of benchmark scores across Geekbench and Passmark, while the RTX PRO 6000D has only a single 3DMark Steel Nomad DX12 result. This makes a direct head-to-head numerical comparison impossible for most workloads, but the available data and architectural specifications still paint a clear picture of their relative positioning.

Head-to-Head Benchmarks

The head-to-head benchmark table is empty, meaning the two GPUs have not been tested with the same workloads in this database. Consequently, we cannot report direct score deltas between the two. Instead, we must rely on their respective average benchmark scores and nearest-rival comparisons to infer relative performance. The AMD Radeon Pro 5500M achieves an average benchmark score of 11528 across its ten tests, placing it in the 51st percentile of all GPUs. Its strongest result is a Geekbench Metal score of 38235, followed by a Geekbench Vulkan score of 35134 and a Geekbench OpenCL score of 31088. In Passmark, the Radeon Pro 5500M scores 6732 in G3D, 3240 in GPU Compute, 648 in G2D, and much lower in legacy DirectX tests, ranging from 96 in DirectX 9 down to 29 in DirectX 12.

The NVIDIA RTX PRO 6000D, by contrast, has a single benchmark result: a 3DMark Steel Nomad DX12 score of 11088. This gives it an average benchmark score of 11088 and a percentile rank of 50, nearly identical to the Radeon Pro 5500M's 51st percentile. However, this near-parity in percentile ranking is misleading because the two scores come from completely different test suites. The Radeon Pro 5500M's 11528 average is derived from a mix of API-specific and synthetic tests, while the RTX PRO 6000D's 11088 comes from one modern DirectX 12 test. The nearest rivals for the RTX PRO 6000D highlight this discrepancy: its avgScore of 11088 is within 0.1% of the AMD Radeon RX 550 (11075) and 0.4% of the NVIDIA GeForce GTX 1650 SUPER (11047), both of which are far lower-end parts. This does not mean the RTX PRO 6000D is comparable to those GPUs; it only means that in the single test recorded, the scores happen to cluster.

For the Radeon Pro 5500M, its nearest rivals in average score include the NVIDIA Tesla K20c (11479, +0.4%), the AMD Radeon RX 7800 XT (11627, -0.8%), the NVIDIA GeForce GTX 1660 (11680, -1.3%), and the NVIDIA GeForce GTX 780M (11261, +2.4%). These deltas are all within a few percentage points, indicating that the Radeon Pro 5500M's average performance sits in a dense pack of mid-range GPUs. The absence of any overlapping benchmark between the two items means we cannot state a single definitive win for either side; the data only allows us to note that the Radeon Pro 5500M has broader benchmark coverage and a slightly higher average score, while the RTX PRO 6000D has a singular, modern DirectX 12 score that is numerically lower.

Architecture Differences

The architectural gap between the two GPUs is immense. The AMD Radeon Pro 5500M is built on the Navi 14 chip using the RDNA 1.0 architecture, fabricated on a 7 nm process at TSMC. It packs 6,400 million transistors into a die size of 158 mm², yielding a transistor density of 40.5 million per square millimeter. In contrast, the NVIDIA RTX PRO 6000D uses the GB202 chip with the Blackwell 2.0 architecture, also fabricated by TSMC but on a 5 nm process. This chip contains 92,200 million transistors across a 750 mm² die, giving a transistor density of 122.9 million per square millimeter. That is roughly three times the transistor density and over fourteen times the total transistor count of the Radeon Pro 5500M.

The compute resources differ by an order of magnitude. The Radeon Pro 5500M has 1536 shading units, 96 texture mapping units, and 32 raster output pipelines. It has no dedicated ray tracing cores and no tensor cores. The RTX PRO 6000D, meanwhile, has 24064 shading units, 752 TMUs, and 192 ROPs. It includes 188 ray tracing cores and 752 tensor cores, enabling hardware-accelerated ray tracing and AI workloads that the Radeon Pro 5500M cannot perform in hardware. The FP32 throughput tells the story: the Radeon Pro 5500M delivers 4.454 TFLOPS, while the RTX PRO 6000D delivers 110.1 TFLOPS, a 24.7x difference. For FP16, the Radeon Pro 5500M reaches 8.909 TFLOPS via a 2:1 ratio, whereas the RTX PRO 6000D sustains 110.1 TFLOPS at a 1:1 ratio, meaning no throughput penalty for reduced precision.

Memory architecture is equally divergent. The Radeon Pro 5500M uses 8 GB of GDDR6 on a 128-bit bus, producing 192.0 GB/s of bandwidth. The RTX PRO 6000D uses 96 GB of GDDR7 on a 512-bit bus, producing 1.79 TB/s of bandwidth. That is a 9.3x increase in bandwidth and a 12x increase in capacity. The pixel rate for the Radeon Pro 5500M is 46.40 GPixel/s, while the RTX PRO 6000D achieves 439.3 GPixel/s. Texture rate is 139.2 GTexel/s versus 1,720.6 GTexel/s. The RTX PRO 6000D also supports PCIe 5.0 x16, whereas the Radeon Pro 5500M is limited to PCIe 4.0 x8.

Where Each One Wins

The Radeon Pro 5500M wins in the context of its intended mobile, low-power environment. Its 85 W TDP and lack of external power connectors make it suitable for portable devices, whereas the RTX PRO 6000D requires a 300 W TDP, a 1x 16-pin power connector, and a suggested 700 W power supply. The Radeon Pro 5500M is also smaller in scope: it is listed with a “Portable Device Dependent” display output, while the RTX PRO 6000D is a dual-slot card measuring 267 mm in length, 111 mm in height, and 40 mm in width. For legacy API support, the Radeon Pro 5500M has Passmark scores for DirectX 9 (96), DirectX 10 (36), and DirectX 11 (42), which are absent for the RTX PRO 6000D. This suggests the older GPU retains some relevance for older workloads, though its DirectX 12 score of 29 is very low.

The RTX PRO 6000D wins in every absolute performance category recorded. Its 110.1 TFLOPS FP32 and FP16 throughput, 1.79 TB/s memory bandwidth, and 96 GB capacity are far beyond the Radeon Pro 5500M's capabilities. It also supports DirectX 12 Ultimate (12_2), while the Radeon Pro 5500M is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4, but the RTX PRO 6000D adds hardware ray tracing and tensor cores, making it the only one of the two capable of modern ray-traced rendering and AI-accelerated tasks. The RTX PRO 6000D is also an active product, released on 2025-03-17, whereas the Radeon Pro 5500M is end-of-life, released on 2019-11-12.

For a user choosing between them today, the decision is straightforward based on workload. The Radeon Pro 5500M is a legacy mobile part with modest compute, suitable for basic 3D and compute tasks in a laptop. The RTX PRO 6000D is a workstation-class accelerator for demanding professional workloads, with 188 ray tracing cores and 752 tensor cores providing capabilities the Radeon Pro 5500M lacks entirely. The 3DMark Steel Nomad score of 11088 for the RTX PRO 6000D, even if it is a single data point, is a modern DirectX 12 test that the Radeon Pro 5500M has no equivalent for. The RTX PRO 6000D also has a launch MSRP of 8,565 USD, which we state for reference only.
