GPU Comparison

The NVIDIA TITAN V and NVIDIA T550 Mobile occupy opposite ends of NVIDIA’s professional and consumer GPU spectrum. The TITAN V is a dual-slot, 250 W desktop flagship built on the Volta architecture, while the T550 Mobile is a 23 W integrated-class mobile part based on Turing. Benchmark data shows a decisive performance gap, but the two chips also differ fundamentally in memory, throughput, and target use cases. Below, the data from the the benchmark database is analyzed step by step.

Head-to-Head Benchmarks

The head-to-head comparison includes only two shared benchmark tests: Geekbench OpenCL and Geekbench Vulkan. In both, the NVIDIA TITAN V wins by a wide margin. In Geekbench OpenCL, the TITAN V scores 157,265 points against the T550 Mobile’s 35,521 points. That is a delta of 342.7% in favor of the TITAN V. In Geekbench Vulkan, the TITAN V scores 152,117 points versus 30,801 points for the T550 Mobile, a delta of 393.9%. These are not marginal differences; the TITAN V more than quadruples the T550 Mobile’s Vulkan score and more than triples its OpenCL score.

The TITAN V’s average benchmark score across all its recorded tests is 34,355. The T550 Mobile’s average benchmark score is 33,161. Despite the massive head-to-head deltas, the average scores are relatively close because the T550 Mobile only has two recorded benchmarks, both of which are compute-heavy, while the TITAN V’s average includes several Passmark tests with lower scores (e.g., Passmark DirectX 12 at 81, Passmark DirectX 10 at 153). The TITAN V’s Passmark G3D score is 19,805, and its Passmark GPU Compute score is 9,263, which are strong absolute numbers but drag the average down when combined with the low DirectX scores. The T550 Mobile’s average is based solely on its two Geekbench results, which are 35,521 and 30,801, producing a higher per-test mean.

The TITAN V ranks in the 79th percentile among all GPUs, while the T550 Mobile sits in the 77th percentile. This is a narrow percentile gap, reflecting that percentile rankings are based on the entire pool of GPUs, not just the head-to-head tests. The TITAN V’s nearest rivals include the NVIDIA RTX A1000 (average score 34,207, delta 0.4%) and the NVIDIA RTX A2000 12 GB (average score 34,154, delta 0.6%), both of which it slightly edges out. The T550 Mobile’s nearest rivals include the NVIDIA GeForce RTX 3050 Mobile (average score 33,170, delta 0%) and the NVIDIA T600 Mobile (average score 32,849, delta 1%), showing it is competitive with those parts.

Architecture Differences

The two GPUs are built on the same 12 nm process node from TSMC, but that is where the similarity ends. The TITAN V uses the GV100 chip, part of the Volta architecture, while the T550 Mobile uses the TU117 chip from the Turing architecture. The TITAN V’s die is 815 mm² and contains 21,100 million transistors, yielding a transistor density of 25.9M per mm². The T550 Mobile’s die is only 200 mm² with 4,700 million transistors, for a density of 23.5M per mm². The TITAN V is physically much larger and more complex.

Memory configurations are drastically different. The TITAN V has 12 GB of HBM2 memory on a 3072-bit bus, achieving 651.3 GB/s of bandwidth. The T550 Mobile has 4 GB of GDDR6 memory on a 64-bit bus, providing 96.00 GB/s. The TITAN V’s memory bandwidth is nearly seven times higher, which directly impacts compute-heavy workloads. The TITAN V’s memory clock is 848 MHz (1696 Mbps effective), while the T550 Mobile’s memory clock is 1500 MHz (12 Gbps effective). The T550 Mobile has a higher raw memory clock, but the narrow bus width severely limits total bandwidth.

Compute resources also differ by an order of magnitude. The TITAN V has 5,120 shading units, 320 texture mapping units (TMUs), and 96 raster operations pipelines (ROPs). The T550 Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs. The TITAN V also includes 640 tensor cores, which the T550 Mobile lacks entirely. Neither GPU has ray tracing cores. The TITAN V’s pixel rate is 139.7 GPixel/s and its texture rate is 465.6 GTexel/s, versus 53.28 GPixel/s and 106.6 GTexel/s for the T550 Mobile. In terms of floating-point performance, the TITAN V delivers 14.90 TFLOPS FP32 and 29.80 TFLOPS FP16 (2:1), while the T550 Mobile delivers 3.410 TFLOPS FP32 and 6.820 TFLOPS FP16 (2:1). The TITAN V is roughly 4.4 times faster in FP32 and 4.4 times faster in FP16.

Clock speeds are closer than the compute resources might suggest. The TITAN V has a base clock of 1200 MHz and a boost clock of 1455 MHz. The T550 Mobile has a base clock of 1065 MHz and a boost clock of 1665 MHz. The T550 Mobile actually boosts higher, but with far fewer execution units, that higher clock does not translate into competitive throughput.

Where Each One Wins

The TITAN V wins in every measurable benchmark category where both are tested. In Geekbench OpenCL, it is 342.7% ahead. In Geekbench Vulkan, it is 393.9% ahead. The TITAN V also has a broader benchmark footprint, with scores across 3DMark Steel Nomad (3,565), Passmark DirectX 9 (213), DirectX 10 (153), DirectX 11 (152), DirectX 12 (81), G2D (937), G3D (19,805), and GPU Compute (9,263). The T550 Mobile has no recorded scores in any of those Passmark or 3DMark tests, meaning its only strengths are in the two Geekbench compute tests, where it still loses decisively.

The TITAN V’s strengths are in high-bandwidth, high-throughput compute tasks. Its 651.3 GB/s memory bandwidth, 640 tensor cores, and 14.90 TFLOPS FP32 make it suitable for heavy compute workloads such as scientific simulation, deep learning inference (via tensor cores), and complex 3D rendering. The T550 Mobile, with its 96.00 GB/s bandwidth and 3.410 TFLOPS FP32, is suited for light mobile workloads where power is a constraint. Its 23 W TDP and integrated form factor (IGP slot width, no power connectors) make it appropriate for thin-and-light laptops where battery life and heat are more important than raw performance.

For gaming, the TITAN V’s Passmark G3D score of 19,805 and DirectX 11 score of 152 indicate solid DirectX 11 capability, though its DirectX 12 score of 81 is lower relative to its other scores. The T550 Mobile has no gaming benchmarks in the data, so no direct gaming conclusion can be drawn from the the benchmark database. The TITAN V’s dual-slot design, 250 W TDP, and 600 W suggested PSU mean it requires a desktop chassis with substantial cooling, while the T550 Mobile’s portable-device-dependent display outputs and null dimensions reflect its mobile-only role.

Q: Which GPU has a higher boost clock?

A: The T550 Mobile has a higher boost clock at 1665 MHz, compared to the TITAN V’s 1455 MHz. However, the TITAN V has far more shading units (5,120 vs. 1,024).

Q: What is the TITAN V’s average benchmark score relative to its nearest rival?

A: The TITAN V’s average benchmark score is 34,355. Its nearest rival, the NVIDIA RTX A1000, has an average score of 34,207, which is 0.4% lower.

The Verdict

The data is unambiguous: the NVIDIA TITAN V is the superior performer in every shared benchmark. It wins both head-to-head tests with deltas of 342.7% and 393.9%. Its average benchmark score of 34,355 is higher than the T550 Mobile’s 33,161, and its percentile ranking (79th) is two points above the T550 Mobile’s (77th). For any workload that requires compute throughput, memory bandwidth, or shading power, the TITAN V is the clear choice.

The T550 Mobile, however, is not without purpose. Its 23 W TDP, IGP slot width, and lack of power connectors make it a low-power part designed for portable systems. It has no tensor cores, a 64-bit memory bus, and 4 GB of VRAM, all of which cap its performance. But its higher boost clock (1665 MHz) and compact design mean it can fit in devices where the TITAN V’s 250 W TDP and dual-slot cooler would be impossible. The TITAN V’s launch MSRP is 2,999 USD, which reflects its position as a flagship compute card.

Pick the TITAN V if you need maximum compute performance, tensor core acceleration, or high-bandwidth memory. Pick the T550 Mobile if you are constrained by power and space and only need light compute capability. The two are not direct competitors; the data shows the TITAN V dominating in performance, while the T550 Mobile trades performance for portability and efficiency.
