NVIDIA GeForce RTX 2080 Ti vs NVIDIA T550 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive advantage for the NVIDIA GeForce RTX 2080 Ti in the two shared benchmark tests. In Geekbench OpenCL, the RTX 2080 Ti scores 128,171 points against 35,521 for the T550 Mobile, a delta of 72.3 percent in favor of the desktop card. The gap widens further in Geekbench Vulkan, where the RTX 2080 Ti posts 132,930 points versus 30,801 for the T550 Mobile, representing a 76.8 percent lead. These are not marginal differences; the RTX 2080 Ti delivers roughly 3.6 times the OpenCL performance and 4.3 times the Vulkan performance of the mobile workstation part.

The T550 Mobile wins no head-to-head comparisons. Out of two recorded matchups, the RTX 2080 Ti takes both. The T550 Mobile's average benchmark score across its two tests is 33,161, while the RTX 2080 Ti's average across its ten tests is 29,783. That apparent contradiction, where the slower part in direct comparison has a higher average, reflects the different test suites each card was subjected to. The T550 Mobile was evaluated only with Geekbench workloads, while the RTX 2080 Ti was also run through Passmark tests, several of which (DirectX 9 at 235, DirectX 11 at 190, DirectX 10 at 153) are legacy APIs that drag down its overall average. The database's percentile ranking confirms the hierarchy: the T550 Mobile sits at the 77th percentile of all GPUs, while the RTX 2080 Ti sits at the 75th percentile.

Where Each One Wins

Based strictly on the benchmark data, the RTX 2080 Ti wins every scenario where both cards have been measured. The OpenCL result of 128,171 versus 35,521 indicates that compute-heavy workloads, such as rendering, simulation, or data processing tasks that leverage OpenCL, will see a massive uplift on the RTX 2080 Ti. The Vulkan result of 132,930 versus 30,801 similarly points to a large advantage in modern graphics APIs, which are common in gaming and real-time visualization. The T550 Mobile has no recorded benchmark win to claim.

However, the T550 Mobile's niche is not reflected in raw speed but in its physical and power profile. The database lists the T550 Mobile with a TDP of 23 W and an IGP slot width, meaning it is designed for compact, power-constrained systems. The RTX 2080 Ti, by contrast, carries a 250 W TDP, a dual-slot cooler, and requires two 8-pin power connectors plus a 600 W suggested PSU. For workloads where the absolute score is secondary to integration constraints, the T550 Mobile is the only viable option between the two. The RTX 2080 Ti also lacks any portable form factor, measuring 267 mm in length, 116 mm in height, and 35 mm in width. The T550 Mobile's display outputs are listed as portable device dependent, reinforcing its mobile-oriented design.

The RTX 2080 Ti further extends its lead in feature support. It includes 68 ray tracing cores and 544 tensor cores, while the T550 Mobile lists no ray tracing or tensor core counts. The RTX 2080 Ti also supports DirectX 12 Ultimate (12_2), whereas the T550 Mobile is limited to DirectX 12 (12_1). For any application that can utilize hardware ray tracing or DirectX 12 Ultimate features, the RTX 2080 Ti is the clear choice. The T550 Mobile does match the RTX 2080 Ti on OpenGL 4.6 and Vulkan 1.4 support, so legacy or cross-platform workloads that rely on those APIs will run on both, though with the performance disparity already noted.

The Verdict

The data points to a straightforward conclusion for most users: the NVIDIA GeForce RTX 2080 Ti is overwhelmingly faster in every measured benchmark. Its Geekbench OpenCL score is 72.3 percent higher, and its Geekbench Vulkan score is 76.8 percent higher. For anyone building a desktop workstation or gaming rig where power draw and physical size are not limiting factors, the RTX 2080 Ti is the superior choice. Its 13.45 TFLOPS of FP32 performance versus 3.410 TFLOPS for the T550 Mobile, combined with 11 GB of GDDR6 memory on a 352-bit bus delivering 616.0 GB/s of bandwidth, makes it suitable for large datasets, high-resolution textures, and compute-intensive tasks. The T550 Mobile's 4 GB memory on a 64-bit bus with 96.00 GB/s bandwidth is a fraction of that capacity and throughput.

The T550 Mobile is for a different audience. Its 23 W TDP and IGP slot width mean it can be embedded in systems where a dual-slot, 250 W card cannot physically fit or be powered. The database shows no performance overlap where the T550 Mobile wins, so the only reason to select it over the RTX 2080 Ti is the form factor and power envelope. The T550 Mobile's predecessor is the Quadro Pascal-M and its successor is Ampere-MW, indicating it belongs to a mobile professional line. The RTX 2080 Ti's predecessor is GeForce 10 and its successor is GeForce 30, placing it in the consumer enthusiast segment.

For a laptop or compact workstation that needs a discrete GPU with a low power draw, the T550 Mobile is the only option of the two. For everything else, the RTX 2080 Ti's recorded performance leaves no contest. The RTX 2080 Ti also carries a launch MSRP of 999 USD, which is a single data point for historical reference; the T550 Mobile has no launch MSRP listed. The production status for both is end-of-life, so neither is a current-generation purchase, but the performance gap remains as recorded.

Architecture Differences

The two GPUs share the Turing architecture and the same 12 nm TSMC process node, but they diverge sharply in scale and capability. The T550 Mobile uses the TU117 chip, which contains 4,700 million transistors on a 200 mm² die, yielding a transistor density of 23.5M per mm². The RTX 2080 Ti uses the TU102 chip, which packs 18,600 million transistors onto a 754 mm² die, with a density of 24.7M per mm². The die size difference is substantial, nearly four times the area, which directly enables the RTX 2080 Ti's larger execution resources.

The RTX 2080 Ti has 4,352 shading units, 272 texture mapping units, and 88 ROPs. The T550 Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs. This 4.25x difference in shading units aligns closely with the FP32 performance gap of 13.45 TFLOPS versus 3.410 TFLOPS. The RTX 2080 Ti also includes specialized hardware in the form of 68 ray tracing cores and 544 tensor cores, which the T550 Mobile does not list at all. This means the RTX 2080 Ti can accelerate ray-traced rendering and AI inference workloads in hardware, while the T550 Mobile would have to rely on compute shaders or lack those features entirely.

The memory subsystem is another major architectural divider. The RTX 2080 Ti's 11 GB GDDR6 is accessed via a 352-bit bus at 14 Gbps effective, producing 616.0 GB/s of bandwidth. The T550 Mobile's 4 GB GDDR6 uses a 64-bit bus at 12 Gbps effective, yielding 96.00 GB/s. The bandwidth difference is over six-fold, which matters for high-resolution textures, large compute buffers, and any workload that is memory-bound. The RTX 2080 Ti's pixel rate of 136.0 GPixel/s and texture rate of 420.2 GTexel/s dwarf the T550 Mobile's 53.28 GPixel/s and 106.6 GTexel/s, respectively.

The API support also differs. The RTX 2080 Ti supports DirectX 12 Ultimate (12_2), which includes features like hardware ray tracing, variable rate shading, and mesh shaders. The T550 Mobile is limited to DirectX 12 (12_1), which lacks those newer tiers. Both support OpenGL 4.6 and Vulkan 1.4, so cross-platform API coverage is identical for those two standards.
