NVIDIA GeForce GTX TITAN X vs NVIDIA T550 Mobile Comparison

Where Each One Wins

The head-to-head data paints a clear picture: the NVIDIA GeForce GTX TITAN X takes both recorded benchmark wins. In Geekbench OpenCL, the TITAN X scores 41471 against 35521 for the T550 Mobile, a 16.8% advantage. The gap widens dramatically in Geekbench Vulkan, where the TITAN X posts 49397 versus 30801, a 60.4% lead. There is no benchmark category in the recorded data where the T550 Mobile comes out ahead.

However, the use-case split is not simply about raw score supremacy. The TITAN X is a desktop flagship from the GeForce 900 generation, built on the GM200 chip with Maxwell 2.0 architecture. It carries 12 GB of GDDR5 memory across a 384-bit bus, yielding 336.6 GB/s of bandwidth. The T550 Mobile is a Turing-based mobile part with 4 GB of GDDR6 on a 64-bit bus, delivering 96.00 GB/s. These are fundamentally different devices for different physical contexts. The TITAN X is a dual-slot, 250 W card requiring a 600 W power supply, while the T550 Mobile is an IGP-class mobile chip drawing just 23 W with no power connectors. The T550 Mobile's entire reason for existing is low-power integration into portable systems, and within that scope it is not competing on the same playing field as a desktop behemoth.

The recorded data shows the TITAN X wins in every shared test, but the T550 Mobile's advantage is in efficiency and form factor, not in raw benchmark scores. The T550 Mobile's 23 W TDP compared to 250 W means it can operate in systems where the TITAN X physically cannot fit or be powered. The TITAN X, conversely, wins where performance per watt is less relevant than absolute throughput. The percentile data reinforces this: the TITAN X sits at the 80th percentile of all GPUs, while the T550 Mobile sits at the 77th percentile. Despite the TITAN X winning both head-to-head tests, the percentile gap is modest, suggesting that in the broader GPU landscape, these two parts are not as far apart as the raw delta might imply.

Architecture Differences

The two GPUs come from different architectural eras and process nodes. The TITAN X uses the GM200 chip on a 28 nm TSMC process, packing 8,000 million transistors into a 601 mm² die, giving a transistor density of 13.3 million per mm². The T550 Mobile uses the TU117 chip on a 12 nm TSMC process, with 4,700 million transistors in a 200 mm² die, for a density of 23.5 million per mm². The T550 Mobile's newer node allows nearly double the transistor density despite having roughly 41% fewer transistors overall.

Architecturally, the TITAN X is Maxwell 2.0, while the T550 Mobile is Turing. The TITAN X belongs to the GeForce 900 generation, with its predecessor being GeForce 700 and its successor GeForce 10. The T550 Mobile belongs to the Quadro Turing-M (Tx000) generation, succeeding Quadro Pascal-M and preceding Ampere-MW. Neither GPU has dedicated ray tracing cores or tensor cores according to the recorded data, so the Turing generation advantage here does not include RT or Tensor features.

The compute resources differ substantially. The TITAN X has 3072 shading units, 192 texture mapping units, and 96 render output units. The T550 Mobile has 1024 shading units, 64 TMUs, and 32 ROPs. The TITAN X has exactly three times the shading units, three times the TMUs, and three times the ROPs of the T550 Mobile. This structural ratio explains much of the performance delta, though the T550 Mobile's higher boost clock of 1665 MHz versus 1089 MHz partially compensates.

Memory architecture is another major divergence. The TITAN X uses 12 GB of GDDR5 with a 384-bit bus, while the T550 Mobile uses 4 GB of GDDR6 with a 64-bit bus. The memory clock readings differ: the TITAN X runs at 1753 MHz with 7 Gbps effective, while the T550 Mobile runs at 1500 MHz with 12 Gbps effective. The newer GDDR6 standard in the T550 Mobile achieves higher effective data rates per pin, but the narrow 64-bit bus limits total bandwidth to 96.00 GB/s versus 336.6 GB/s for the TITAN X. The TITAN X has 3.5 times the memory bandwidth of the T550 Mobile.

Both GPUs support DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. Both use PCIe 3.0 x16. The TITAN X offers display outputs of 1x DVI, 1x HDMI 2.0, and 3x DisplayPort 1.2, while the T550 Mobile's display outputs are listed as "Portable Device Dependent," meaning they are determined by the laptop manufacturer.

Head-to-Head Benchmarks

The Geekbench OpenCL result gives the TITAN X a 16.8% advantage, scoring 41471 against 35521. This is a meaningful but not overwhelming lead. The TITAN X's 6.691 TFLOPS of FP32 performance versus the T550 Mobile's 3.410 TFLOPS suggests a raw compute advantage of roughly two to one, yet the OpenCL score gap is smaller. This could reflect the T550 Mobile's higher boost clock of 1665 MHz versus 1089 MHz, or differences in how OpenCL workloads utilize memory bandwidth and driver optimizations.

The Geekbench Vulkan result tells a different story. The TITAN X scores 49397, which is 60.4% higher than the T550 Mobile's 30801. Vulkan workloads often stress memory bandwidth and geometry throughput, areas where the TITAN X's 384-bit bus and 96 ROPs provide a massive structural advantage. The TITAN X also has a pixel rate of 104.5 GPixel/s and a texture rate of 209.1 GTexel/s, compared to 53.28 GPixel/s and 106.6 GTexel/s for the T550 Mobile. The TITAN X doubles the T550 Mobile in both pixel and texture throughput.

The T550 Mobile does have one recorded advantage in compute features: it supports FP16 at 6.820 TFLOPS with a 2:1 ratio, while the TITAN X has no recorded FP16 data. This means in workloads that can exploit half-precision arithmetic on Turing hardware, the T550 Mobile could theoretically outperform its FP32 baseline, but no benchmark data in the database confirms this in practice. The recorded benchmarks only cover OpenCL and Vulkan, and the TITAN X wins both.

The TITAN X also has a higher average benchmark score across all recorded tests: 36530 versus 33161 for the T550 Mobile, a difference of roughly 10.2%. Both GPUs are end-of-life products. The TITAN X was released on 2015-03-16, while the T550 Mobile has no recorded release date.

The Verdict

The data supports a straightforward conclusion for raw performance: the NVIDIA GeForce GTX TITAN X wins every recorded benchmark against the NVIDIA T550 Mobile. In OpenCL, it leads by 16.8%; in Vulkan, by 60.4%. Its average benchmark score of 36530 exceeds the T550 Mobile's 33161 by about 10%. The TITAN X also sits at the 80th percentile of all GPUs versus the T550 Mobile's 77th percentile, placing it higher in the overall distribution.

However, the choice between these two parts is not a simple performance ranking. The TITAN X demands a 250 W power budget, a 600 W suggested power supply, dual-slot space, and a 267 mm card length. The T550 Mobile draws 23 W, requires no power connectors, and is an IGP-class mobile chip with no dimensions listed. Anyone building a desktop workstation with ample power and space should pick the TITAN X without hesitation based on the recorded data. Anyone designing a thin, low-power laptop where the T550 Mobile's 23 W TDP is the only feasible option has no real choice; the T550 Mobile is the only one of the two that fits that physical envelope.

The T550 Mobile's nearest rival is the NVIDIA GeForce RTX 3050 Mobile with an average score of 33170, a 0% delta, meaning the T550 Mobile is effectively tied with that GPU in average performance. The TITAN X's nearest rival is the AMD Radeon RX 5300M at 36529, also a 0% delta. This means the TITAN X is not dramatically faster than its closest competitors, and the T550 Mobile is not dramatically slower than its own. The head-to-head gap between the two reviewed GPUs is larger than the gaps to their respective nearest rivals.

For users who need maximum compute throughput in a desktop context, the TITAN X is the clear choice. For users who need a low-power mobile GPU, the T550 Mobile is the only option between the two, and its 77th percentile standing shows it is a respectable performer within its class. The data does not indicate any scenario where the T550 Mobile outperforms the TITAN X in the recorded benchmarks.
