NVIDIA RTX PRO 4500 Blackwell vs NVIDIA T550 Mobile Comparison

The NVIDIA T550 Mobile and NVIDIA RTX PRO 4500 Blackwell are extremely different GPUs, separated by multiple generations and performance classes. The data shows the RTX PRO 4500 Blackwell is the dominant performer, but the T550 Mobile holds a distinct niche for ultra-low-power, integrated systems. The RTX PRO 4500 Blackwell delivers a massive generational leap in nearly every metric, while the T550 Mobile is an end-of-life entry-level part.

Q: Which GPU has a higher average benchmark score?

A: The T550 Mobile has a higher average benchmark score of 33161, compared to the RTX PRO 4500 Blackwell's 31532. However, this is due to different benchmark suites, as the RTX PRO 4500 Blackwell has more diverse test results including Passmark and 3DMark tests.

Q: What are the power consumption differences?

A: The T550 Mobile has a TDP of 23 W and is an IGP (integrated graphics processor) with no power connectors. The RTX PRO 4500 Blackwell has a TDP of 200 W, uses a dual-slot design with a 1x 16-pin power connector, and requires a suggested PSU of 550 W.

Architecture Differences

The two GPUs represent entirely different architectural eras. The T550 Mobile is built on the Turing architecture using the TU117 chip, manufactured on TSMC's 12 nm process. In contrast, the RTX PRO 4500 Blackwell uses the Blackwell 2.0 architecture with the GB203 chip, produced on a 5 nm process. The process node shrink from 12 nm to 5 nm enables the RTX PRO 4500 Blackwell to pack significantly more transistors: 45,600 million versus 4,700 million, despite a die size increase from 200 mm² to 378 mm².

The Blackwell GPU adds dedicated hardware that the Turing part lacks entirely. The RTX PRO 4500 Blackwell includes 82 RT cores for ray tracing and 328 Tensor cores for AI acceleration, while the T550 Mobile has none of these features. The shading unit count also differs dramatically, with the RTX PRO 4500 Blackwell featuring 10496 shading units compared to the T550 Mobile's 1024. The Blackwell chip also has 328 TMUs and 112 ROPs, versus 64 TMUs and 32 ROPs on the Turing chip.

Memory architecture represents another fundamental split. The T550 Mobile uses GDDR6 memory at 1500 MHz (12 Gbps effective), while the RTX PRO 4500 Blackwell uses GDDR7 at 1750 MHz (28 Gbps effective). The Blackwell card also supports PCIe 5.0 x16, while the T550 Mobile is limited to PCIe 3.0 x16. API support differs as well: the RTX PRO 4500 Blackwell supports DirectX 12 Ultimate (12_2), while the T550 Mobile only reaches DirectX 12 (12_1).

Where Each One Wins

The T550 Mobile wins on power efficiency and form factor. With a 23 W TDP and IGP slot width, it is designed for compact, portable devices where power draw and physical space are at a premium. Its "Portable Device Dependent" display outputs indicate it is built for laptops and mobile workstations. The T550 Mobile also holds a higher percentile ranking at 77 versus the RTX PRO 4500 Blackwell's 76, and it has a higher average benchmark score of 33161 compared to 31532.

The RTX PRO 4500 Blackwell wins on raw performance and features. It delivers 50.53 TFLOPS of FP32 compute versus the T550 Mobile's 3.410 TFLOPS, a 14.8x difference. The Blackwell card supports ray tracing and tensor operations, making it suitable for modern AI workloads and real-time rendering. It also offers 8x the memory capacity (32 GB vs 4 GB) with 9.3x the memory bandwidth (896.0 GB/s vs 96.00 GB/s). The RTX PRO 4500 Blackwell has a 2407 MHz boost clock versus 1665 MHz, and it supports four DisplayPort 2.1b outputs for multi-monitor professional setups.

Head-to-Head Benchmarks

The only shared benchmark test between the two GPUs is Geekbench Vulkan, and the results are decisively one-sided. The RTX PRO 4500 Blackwell scores 221768, while the T550 Mobile scores 30801. This yields a deltaPct of -86.1%, meaning the T550 Mobile trails by 86.1% relative to the Blackwell part. In absolute terms, the RTX PRO 4500 Blackwell is approximately 7.2x faster in this test.

Beyond the shared benchmark, the RTX PRO 4500 Blackwell has additional test results that paint a fuller picture of its capabilities. In 3DMark Steel Nomad DX12, it scores 7025. Passmark results show a G3D score of 33360, a GPU Compute score of 19255, and a G2D score of 1336. Legacy DirectX tests show scores of 397 for DX9, 320 for DX11, 204 for DX10, and 119 for DX12. The T550 Mobile has no comparable data in these tests, but its Geekbench OpenCL score of 35521 offers a point of reference for its compute capabilities, though this is not directly comparable to the Passmark GPU Compute score.

The T550 Mobile's nearest rivals include the NVIDIA GeForce RTX 3050 Mobile with a deltaPct of 0, the AMD Radeon Pro 570 at -0.1%, and the NVIDIA P104-100 at 0.5%. This places the T550 Mobile in a narrow performance band where tiny percentage differences separate competitors. The RTX PRO 4500 Blackwell, by contrast, competes against the NVIDIA TITAN RTX at -0.5%, the GRID M60-1Q at 1%, and the Quadro M5000 at 1%, showing it operates in a much higher performance tier where the T550 Mobile does not appear.

The Verdict

The data clearly shows these are not competing products. The RTX PRO 4500 Blackwell is the superior choice for any workload requiring significant compute power, ray tracing, or large memory capacities. Its 50.53 TFLOPS FP32 performance, 896.0 GB/s memory bandwidth, and 82 RT cores make it a professional-grade solution for rendering, AI inference, and complex scientific simulations. The 32 GB GDDR7 memory capacity alone outclasses the T550 Mobile's 4 GB by an order of magnitude, enabling datasets and scenes that would be impossible on the older card.

The T550 Mobile's only advantages are its 23 W TDP, IGP form factor, and its slightly higher percentile ranking (77 vs 76) and average benchmark score (33161 vs 31532). These metrics reflect its specialized role in portable devices where power efficiency trumps raw performance. For a legacy mobile workstation requiring basic 3D acceleration without dedicated power connectors, the T550 Mobile remains functional but is end-of-life.

The RTX PRO 4500 Blackwell is the definitive choice for professionals needing a modern, active GPU with PCIe 5.0 support and DisplayPort 2.1b outputs. Its 200 W TDP and dual-slot design require a desktop workstation with adequate cooling and a 550 W PSU, but the performance payoff is substantial. The 86.1% Vulkan deltaPct difference is the single clearest metric: the Blackwell GPU is in a different league entirely, and the T550 Mobile should only be selected for its power envelope, not its performance.
