NVIDIA T550 Mobile vs NVIDIA TITAN RTX Comparison

The NVIDIA T550 Mobile and NVIDIA TITAN RTX represent two extreme endpoints of the Turing architecture spectrum. The T550 Mobile is a 23 W integrated-class part designed for ultra-portable workstations, while the TITAN RTX is a 280 W dual-slot desktop behemoth aimed at professional content creation and compute workloads. Benchmark data shows a complete victory for the TITAN RTX in the available head-to-head tests, with the T550 Mobile trailing by over 75% in both OpenCL and Vulkan workloads. However, the T550 Mobile holds a higher percentile ranking (77th) than the TITAN RTX (76th) when compared against all GPUs, illustrating that efficiency and targeted design can yield competitive standing despite overwhelming performance differences.

Where Each One Wins

The TITAN RTX wins every benchmark category where both cards have data. In Geekbench OpenCL, it scores 144,858 points versus the T550 Mobile’s 35,521, a 75.5% advantage. In Geekbench Vulkan, the gap is even larger at 77.4%, with the TITAN RTX posting 136,073 points against 30,801. This makes the TITAN RTX the clear choice for compute-heavy tasks such as rendering, simulation, and machine learning frameworks that leverage OpenCL or Vulkan.

The T550 Mobile’s win is not in raw performance but in positioning. Its 77th percentile ranking against all GPUs is actually one point higher than the TITAN RTX’s 76th percentile, which is remarkable given the massive power and performance disparity. This suggests that the T550 Mobile’s efficiency—23 W TDP versus 280 W—makes it a superior fit for the specific segment of portable, low-power workstations where battery life and thermal constraints are paramount. It also has a 0% deltaPct against the closest rival (NVIDIA GeForce RTX 3050 Mobile), indicating it is perfectly competitive within its own performance class.

For users needing to process large datasets or render complex scenes, the TITAN RTX’s 24 GB memory and 672.0 GB/s bandwidth provide a decisive advantage. The T550 Mobile’s 4 GB and 96.00 GB/s are sufficient for lightweight professional workloads but will bottleneck on high-resolution textures or large models. The data clearly shows the TITAN RTX is the winner for any performance-sensitive task, while the T550 Mobile wins on portability and thermal efficiency.

Architecture Differences

Both GPUs are built on the same 12 nm Turing architecture from TSMC, but they diverge dramatically in implementation. The T550 Mobile uses the TU117 chip with 4,700 million transistors on a 200 mm² die, while the TITAN RTX uses the TU102 chip with 18,600 million transistors on a 754 mm² die. Transistor density is slightly higher on the TITAN RTX (24.7M / mm² versus 23.5M / mm²), indicating a more complex layout.

The TITAN RTX features 4,608 shading units, 288 TMUs, and 96 ROPs, compared to the T550 Mobile’s 1,024 shading units, 64 TMUs, and 32 ROPs. More critically, the TITAN RTX includes 72 RT cores and 576 tensor cores, which are entirely absent from the T550 Mobile. This means the TITAN RTX supports hardware-accelerated ray tracing and AI-accelerated tensor operations, while the T550 Mobile lacks these capabilities entirely.

Memory architecture is another major divergence. The TITAN RTX uses a 384-bit bus with 24 GB of GDDR6 at 14 Gbps effective, yielding 672.0 GB/s bandwidth. The T550 Mobile uses a 64-bit bus with 4 GB of GDDR6 at 12 Gbps effective, yielding just 96.00 GB/s. Clock speeds also favor the TITAN RTX, with a 1350 MHz base and 1770 MHz boost versus 1065 MHz base and 1665 MHz boost on the T550 Mobile. The TITAN RTX also supports DirectX 12 Ultimate (12_2), while the T550 Mobile only supports DirectX 12 (12_1), a meaningful difference for modern game and rendering APIs.

Head-to-Head Benchmarks

The only two benchmarks where both cards have results show a complete domination by the TITAN RTX. In Geekbench OpenCL, the TITAN RTX scores 144,858 against the T550 Mobile’s 35,521. This is a 75.5% delta, meaning the T550 Mobile’s score is less than a quarter of the TITAN RTX’s. This is expected given the 4.8x difference in shading units (4,608 vs 1,024) and the 7x difference in memory bandwidth (672.0 GB/s vs 96.00 GB/s).

The Geekbench Vulkan test shows an even wider gap. The TITAN RTX posts 136,073 points, while the T550 Mobile manages only 30,801. The 77.4% delta reflects the TITAN RTX’s superior geometry processing, texture rate (509.8 GTexel/s vs 106.6 GTexel/s), and pixel throughput (169.9 GPixel/s vs 53.28 GPixel/s). The T550 Mobile’s FP32 performance of 3.410 TFLOPS is roughly one-fifth of the TITAN RTX’s 16.31 TFLOPS, which directly impacts compute workloads in Vulkan.

The TITAN RTX also has substantial wins in its own benchmark suite that the T550 Mobile lacks. Passmark G3D shows 20,491 points, and Passmark GPU Compute shows 10,034 points. The TITAN RTX’s 3DMark Steel Nomad DX12 score of 3,794 further demonstrates its DirectX 12 Ultimate capabilities, which the T550 Mobile cannot access due to its older 12_1 support. Legacy DirectX tests on the TITAN RTX range from 88 (DX12) to 223 (DX9), with G2D at 860, indicating balanced performance across API generations.

The deltaPct values in the nearestRivals data put these scores in perspective. The T550 Mobile’s average benchmark score of 33,161 is nearly identical to the GeForce RTX 3050 Mobile (33,170, 0% delta) and slightly ahead of the T600 Mobile (32,849, 1% delta). Conversely, the TITAN RTX’s average score of 31,676 sits close to the RTX PRO 4500 Blackwell (31,532, 0.5% delta) and Intel Arc Pro A30M (31,894, -0.7% delta). This shows that while the TITAN RTX is absolutely far ahead of the T550 Mobile, both cards are tightly matched with their direct contemporaries in their respective performance tiers.
