NVIDIA GeForce RTX 4080 Mobile vs NVIDIA T550 Mobile Comparison

The Verdict

The benchmark data is unambiguous: the NVIDIA GeForce RTX 4080 Mobile is the dominant performer in this comparison. It wins both recorded head-to-head tests, and the margins are enormous. In OpenCL compute, it delivers 159,575 points against 35,521 for the T550 Mobile, a 349.2% advantage. In Vulkan, the gap widens further: 145,807 versus 30,801, a 373.4% lead. For any workload that relies on GPU compute or modern graphics APIs, the RTX 4080 Mobile is the clear choice. The T550 Mobile, meanwhile, is an end-of-life product from the Turing era, and its data reflects a much older and smaller design. Anyone needing raw performance should select the RTX 4080 Mobile; anyone constrained by power draw or working with legacy applications might consider the T550 Mobile, but only because its 23 W TDP is far lower than the 110 W of the RTX 4080 Mobile. The recorded scores show no scenario where the T550 Mobile wins a performance comparison.

Architecture Differences

The two GPUs come from different architectural generations and are built on different process nodes. The RTX 4080 Mobile uses the AD104 chip, based on Ada Lovelace architecture, and is fabricated on a 5 nm process at TSMC. It packs 35,800 million transistors into a 294 mm² die, giving a transistor density of 121.8 million per square millimeter. The T550 Mobile, in contrast, uses the TU117 chip, based on Turing architecture, and is built on a 12 nm process, also at TSMC. It contains only 4,700 million transistors on a 200 mm² die, resulting in a density of 23.5 million per square millimeter. The difference in node technology is stark: the newer 5 nm process allows over 25 times the transistor density per area compared to the older 12 nm node.

The RTX 4080 Mobile features dedicated ray tracing cores (58 of them) and tensor cores (232 of them), while the T550 Mobile has none listed. This means the RTX 4080 Mobile can accelerate ray-traced workloads and AI-based operations, whereas the T550 Mobile lacks these hardware units entirely. The shading unit count also diverges massively: 7,424 shading units on the RTX 4080 Mobile versus 1,024 on the T550 Mobile. Texture mapping units (TMUs) are 232 versus 64, and render output units (ROPs) are 80 versus 32. These structural differences explain why the RTX 4080 Mobile achieves a texture rate of 386.3 GTexel/s and a pixel rate of 133.2 GPixel/s, while the T550 Mobile manages 106.6 GTexel/s and 53.28 GPixel/s respectively.

API support also differs. The RTX 4080 Mobile supports DirectX 12 Ultimate (12_2), while the T550 Mobile is limited to DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The bus interface is different as well: the RTX 4080 Mobile uses PCIe 4.0 x16, whereas the T550 Mobile uses the older PCIe 3.0 x16 standard.

Head-to-Head Benchmarks

Only two benchmarks are directly comparable between the two GPUs: Geekbench OpenCL and Geekbench Vulkan. In OpenCL, the RTX 4080 Mobile scores 159,575, which is 349.2% higher than the T550 Mobile's 35,521. This is a massive margin, indicating that the RTX 4080 Mobile is roughly 4.5 times faster in this compute workload. In Vulkan, the RTX 4080 Mobile scores 145,807, which is 373.4% higher than the T550 Mobile's 30,801. The Vulkan gap is even larger than OpenCL, suggesting the newer architecture's advantage grows with modern graphics APIs.

The RTX 4080 Mobile also has more recorded benchmark results overall. The database includes scores for PassMark DirectX 10 (157), DirectX 11 (244), DirectX 12 (96), DirectX 9 (286), G2D (929), G3D (24,926), and GPU Compute (11,191) for the RTX 4080 Mobile. The T550 Mobile only has the two Geekbench results recorded. The RTX 4080 Mobile's average benchmark score of 38,135 sits close to its nearest rivals: the GeForce MX570 (38,299, a 0.4% difference), the RTX 5080 Mobile (38,349, a 0.6% difference), and the RTX 4070 (37,648, a 1.3% difference). The T550 Mobile's average of 33,161 is essentially tied with the RTX 3050 Mobile (33,170, a 0.0% difference) and the AMD Radeon Pro 570 (33,207, a 0.1% difference).

Where Each One Wins

The RTX 4080 Mobile wins every performance category where data exists. It is superior in compute (OpenCL and Vulkan), in raw shading throughput (24.72 TFLOPS FP32 versus 3.410 TFLOPS), in memory bandwidth (432.0 GB/s versus 96.00 GB/s), and in texture and pixel fill rates. Its 12 GB memory capacity versus 4 GB also gives it a clear advantage for large datasets and high-resolution textures. The presence of ray tracing and tensor cores means it can handle modern games with ray-traced effects and AI-based features like DLSS, which the T550 Mobile cannot accelerate.

The T550 Mobile's only recorded advantage is power consumption. Its 23 W TDP is less than a quarter of the RTX 4080 Mobile's 110 W. This makes it suitable for laptops where battery life and cooling are priorities, and where the user does not need high-end gaming or compute performance. The T550 Mobile also belongs to the older Turing architecture, which may offer better compatibility with legacy professional applications that predate the Ada Lovelace generation. Its production status is end-of-life, so it is no longer an active product line, but for existing deployments that require low power draw and basic graphics acceleration, the data shows it remains a functional option. However, for any workload that benefits from the RTX 4080 Mobile's massive compute lead, the T550 Mobile cannot compete.
