NVIDIA GeForce RTX 5080 Mobile vs NVIDIA T550 Mobile Comparison

The Verdict

The NVIDIA GeForce RTX 5080 Mobile is in a completely different performance class compared to the NVIDIA T550 Mobile. Based on the recorded data, the RTX 5080 Mobile delivers a 370.1% higher score in Geekbench OpenCL and a 451.1% higher score in Geekbench Vulkan. This is not a close contest by any metric available in the database. The RTX 5080 Mobile sits at the 81st percentile among all GPUs, while the T550 Mobile sits at the 77th percentile, yet the raw score gap is enormous because the percentile ranking compresses the differences at the upper end of the distribution. For any user who needs modern gaming, rendering, or compute workloads, the RTX 5080 Mobile is the only viable choice from this pairing.

The T550 Mobile, with an average benchmark score of 33,161, lands within 0.1% of the GeForce RTX 3050 Mobile and 1% ahead of the T600 Mobile. It is a legacy Turing-based part that remains competitive only against older or lower-tier mobile GPUs. Its 4 GB GDDR6 memory on a 64-bit bus and 96.00 GB/s bandwidth constrain it to light workloads. The RTX 5080 Mobile, by contrast, offers 16 GB GDDR7 on a 256-bit bus with 896.0 GB/s bandwidth, which is roughly 9.3 times the memory bandwidth of the T550 Mobile. For users who require large datasets, high-resolution textures, or any form of ray tracing, the T550 Mobile cannot keep pace.

The production status also tells a story: the RTX 5080 Mobile is Active, while the T550 Mobile is End-of-life. The T550 Mobile's successor is listed as Ampere-MW, confirming that it is a discontinued product. The RTX 5080 Mobile is part of the GeForce 50-series and was released on 2025-04-01. The verdict is straightforward: choose the RTX 5080 Mobile for any performance-sensitive task, and only consider the T550 Mobile if the workload is extremely light and the platform requires its lower 23 W TDP.

Architecture Differences

The RTX 5080 Mobile uses the GB203 chip built on Blackwell 2.0 architecture, fabricated on a 5 nm TSMC process. It contains 45,600 million transistors on a 378 mm² die, giving a transistor density of 120.6M per mm². The T550 Mobile uses the TU117 chip based on Turing architecture, built on a 12 nm TSMC process, with 4,700 million transistors on a 200 mm² die, for a density of 23.5M per mm². The process node advantage is significant: the RTX 5080 Mobile packs roughly 9.7 times the transistor count into a die that is only 1.89 times larger.

The compute configuration differs drastically. The RTX 5080 Mobile has 7,680 shading units, 240 TMUs, and 96 ROPs. The T550 Mobile has 1,024 shading units, 64 TMUs, and 32 ROPs. That is 7.5 times more shading units, 3.75 times more TMUs, and 3 times more ROPs. The RTX 5080 Mobile also includes 60 RT cores and 240 tensor cores, while the T550 Mobile has none listed for either. The pixel rate is 144.0 GPixel/s versus 53.28 GPixel/s, and the texture rate is 360.0 GTexel/s versus 106.6 GTexel/s.

Clock speeds tell a different story. The T550 Mobile has a higher base clock at 1065 MHz versus 975 MHz, and a higher boost clock at 1665 MHz versus 1500 MHz. Yet the RTX 5080 Mobile still achieves 23.04 TFLOPS FP32 performance, compared to 3.410 TFLOPS for the T550 Mobile. The FP16 figures are also telling: the RTX 5080 Mobile delivers 23.04 TFLOPS FP16 at a 1:1 ratio with FP32, while the T550 Mobile delivers 6.820 TFLOPS FP16 at a 2:1 ratio. The memory subsystem is equally divergent: GDDR7 at 28 Gbps effective on a 256-bit bus for the RTX 5080 Mobile, versus GDDR6 at 12 Gbps effective on a 64-bit bus for the T550 Mobile.

The bus interface differs as well. The RTX 5080 Mobile uses PCIe 5.0 x16, while the T550 Mobile uses PCIe 3.0 x16. Both are IGP slot width with no power connectors. API support is similar: both support OpenGL 4.6 and Vulkan 1.4, but the RTX 5080 Mobile supports DirectX 12 Ultimate (12_2), while the T550 Mobile only reaches DirectX 12 (12_1).

Where Each One Wins

The RTX 5080 Mobile wins in every recorded benchmark category. In Geekbench OpenCL, it scores 166,986 against 35,521 for the T550 Mobile, a 370.1% advantage. In Geekbench Vulkan, it scores 169,754 against 30,801, a 451.1% advantage. The wins tally in the head-to-head comparison is 2 for the RTX 5080 Mobile and 0 for the T550 Mobile.

The T550 Mobile's only advantages are power consumption and clock speed. Its TDP is 23 W versus 80 W for the RTX 5080 Mobile. For systems with strict thermal or power budgets, the T550 Mobile could be preferable despite its lower performance. Its higher base and boost clocks also mean that for very short, single-threaded or lightly threaded workloads where the GPU is not the bottleneck, the T550 Mobile may feel more responsive per clock, but the massive core count difference overwhelms this in any parallel workload.

The RTX 5080 Mobile's memory capacity of 16 GB versus 4 GB makes it suitable for larger textures, multiple displays, or compute workloads that exceed the T550 Mobile's frame buffer. The 896.0 GB/s bandwidth versus 96.00 GB/s means memory-bound operations will be dramatically faster on the RTX 5080 Mobile. The RTX 5080 Mobile also supports ray tracing and tensor operations through its 60 RT cores and 240 tensor cores, which the T550 Mobile lacks entirely. For machine learning inference, DLSS, or ray-traced rendering, the RTX 5080 Mobile is the only option.

Head-to-Head Benchmarks

The only two head-to-head benchmark results available are Geekbench OpenCL and Geekbench Vulkan, and both decisively favor the RTX 5080 Mobile.

In Geekbench OpenCL, the RTX 5080 Mobile scores 166,986 points. The T550 Mobile scores 35,521 points. The delta is 370.1%. This is a compute-oriented test that stresses raw throughput across the shading units. The RTX 5080 Mobile's 7,680 shading units versus 1,024, combined with its 896.0 GB/s memory bandwidth, explains the magnitude of the gap. The T550 Mobile's higher boost clock of 1665 MHz cannot compensate for having 7.5 times fewer cores and 9.3 times less memory bandwidth.

In Geekbench Vulkan, the RTX 5080 Mobile scores 169,754 points against 30,801 points for the T550 Mobile, a delta of 451.1%. The Vulkan test tends to exercise driver overhead, draw call throughput, and memory access patterns. The RTX 5080 Mobile's Blackwell architecture, PCIe 5.0 x16 interface, and GDDR7 memory give it a structural advantage. The T550 Mobile's Turing architecture and PCIe 3.0 x16 interface are older generations, which likely contributes to the larger percentage gap in Vulkan compared to OpenCL.

Looking at the broader benchmark suite for the RTX 5080 Mobile alone, its average benchmark score is 38,349. Its nearest rivals include the GeForce MX570 at 38,299 (0.1% behind), the RTX 4080 Mobile at 38,135 (0.6% behind), and the MX570 A at 38,691 (0.9% ahead). This means the RTX 5080 Mobile sits in a very tight cluster of mid-to-high-end mobile GPUs, despite having a much newer architecture. The T550 Mobile's average score is 33,161, with the RTX 3050 Mobile at 33,170 (0% delta), the Radeon Pro 570 at 33,207 (0.1% ahead), and the P104-100 at 32,982 (0.5% behind). The T550 Mobile is therefore competitive within its own tier, but that tier is far below the RTX 5080 Mobile.

The individual benchmark scores for the RTX 5080 Mobile show a wide spread across tests: Passmark G3D at 27,711, Passmark GPU Compute at 12,134, Passmark G2D at 1,095, and Passmark DirectX 9 at 314. The T550 Mobile has no Passmark results recorded, so cross-test comparison is limited to the two Geekbench tests. The RTX 5080 Mobile's Geekbench Vulkan score is higher than its OpenCL score by 2,768 points, while the T550 Mobile's OpenCL score is higher than its Vulkan score by 4,720 points. This suggests the T550 Mobile is relatively weaker in Vulkan, which is consistent with its older architecture and lack of modern API optimizations.

The percentile data reinforces the hierarchy: the RTX 5080 Mobile is at the 81st percentile of all GPUs, and the T550 Mobile is at the 77th. A 4-point percentile gap may sound small, but the underlying score difference of 5,188 points in average benchmark score represents a 15.6% gap. Within the head-to-head, the RTX 5080 Mobile's smallest victory is 370.1%, so in no scenario does the T550 Mobile approach parity. The data is unambiguous: the RTX 5080 Mobile is the superior GPU in every measured dimension except power draw and clock speed.
