NVIDIA GeForce RTX 3080 Ti vs NVIDIA T550 Mobile Comparison

Where Each One Wins

The benchmark data draws a clear line between these two NVIDIA parts. The GeForce RTX 3080 Ti wins every recorded head-to-head test, and the margins are not subtle. In the two shared workloads, Geekbench OpenCL and Geekbench Vulkan, the desktop-class card leads by 378.7% and 525.6% respectively. That is not a competitive gap; it is a different performance tier entirely.

The RTX 3080 Ti is built for high-end desktop rendering, ray tracing, and compute workloads where raw throughput matters. Its average benchmark score of 41,187 places it in the 83rd percentile of all GPUs in the database, and its nearest rivals are the AMD Radeon Pro 5300 (0.8% ahead), the NVIDIA Tesla M40 24 GB (1.2% behind), the NVIDIA Tesla M40 (1.7% behind), and the GeForce RTX 5070 (2% behind). The recorded data shows a card that sits in a dense pack of powerful workstation and desktop accelerators, trading places with those rivals by single-digit percentage points.

The T550 Mobile, by contrast, is a low-power mobile workstation part with a 23 W TDP. Its average benchmark score of 33,161 puts it in the 77th percentile, and its nearest rivals are the GeForce RTX 3050 Mobile (0% delta), the AMD Radeon Pro 570 (0.1% behind), the NVIDIA P104-100 (0.5% ahead), and the T600 Mobile (1% ahead). The T550 Mobile is effectively tied with those peers, which indicates it is a competent entry-level mobile GPU but nowhere near the RTX 3080 Ti's league. The use-case split is simple: the RTX 3080 Ti wins on absolute performance for desktop workstations and enthusiast builds, while the T550 Mobile wins on integration and power efficiency for portable devices.

Architecture Differences

The two GPUs come from different NVIDIA architectures and different fabs. The RTX 3080 Ti uses the GA102 chip on the Ampere architecture, fabricated by Samsung on an 8 nm process. It packs 28,300 million transistors onto a 628 mm² die, giving a transistor density of 45.1 million per square millimeter. The T550 Mobile uses the TU117 chip on the Turing architecture, fabricated by TSMC on a 12 nm process. That chip contains 4,700 million transistors on a 200 mm² die, with a density of 23.5 million per square millimeter. The RTX 3080 Ti therefore has roughly six times the transistor count and a die more than three times larger, while also achieving nearly double the transistor density.

The memory subsystems are equally divergent. The RTX 3080 Ti has 12 GB of GDDR6X memory on a 384-bit bus, with 912.4 GB/s of bandwidth and 19 Gbps effective memory speed. The T550 Mobile has 4 GB of GDDR6 memory on a 64-bit bus, with 96.00 GB/s of bandwidth and 12 Gbps effective memory speed. The desktop card offers nearly ten times the memory capacity and close to ten times the bandwidth.

Compute resources follow the same pattern. The RTX 3080 Ti has 10,240 shading units, 320 TMUs, and 112 ROPs. It also includes 80 RT cores and 320 tensor cores, meaning it supports hardware-accelerated ray tracing on the Turing architecture. The T550 Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs. It has no RT cores and no tensor cores, so the database explicitly records no ray tracing acceleration for that part. FP32 throughput for the RTX 3080 Ti is listed at 34.10 TFLOPS with FP16. The T550 Mobile delivers 3.410 TFLOPS FP32, but FP16 reaches 6.820 TFLOPS with a 2:1 ratio. The RTX 3080 Ti's FP16 and FP32 are equal at 1:1, which reflects its workstation-oriented design.

Head-to-Head Benchmarks

The database records only two shared tests between the RTX 3080 Ti and the T550 Mobile, and the RTX 3080 Ti wins both. In Geekbench OpenCL, the RTX 3080 Ti scores 170,037 against the T550 Mobile's 35,521. That is a 378.7% advantage. In Geekbench Vulkan, the RTX 3080 Ti scores 192,697 against 30,801, a 525.6% advantage. The Vulkan gap is even larger than the OpenCL gap, which suggests the RTX 3080 Ti's architecture scales better with the newer API.

These two tests tell the story of the broader performance divide. The RTX 3080 Ti also has a rich benchmark profile beyond those shared tests, including a 3DMark Steel Nomad DX12 score of 5,077, a Passmark G3D score of 26,896, and a Passmark GPU Compute score of 15,282. It also records legacy Passmark DirectX scores of 184 (DX10), 223 (DX11), 110 (DX12), and 274 (DX9), plus a Passmark G2D score of 1,091. The T550 Mobile has no entries in those tests, so no direct comparison is possible there. The database's wins tally is 2 for the RTX 3080 Ti and 0 for the T550 Mobile.

For context, the RTX 3080 Ti's nearest rivals in the database average between 40,377 and 41,897, all within 2% of its own average of 41,187. The T550 Mobile's nearest rivals average between 32,849 and 33,207, all within 1% of its 33,161. The two cards sit in separate clusters of performance, and the head-to-head deltas reflect that separation.
