Their average benchmark scores, 45152 for the RTX 5090 Mobile and 34561 for the T1000 8 GB, place them in different performance tiers, yet the T1000 still holds a respectable 79th percentile ranking among all GPUs. The data invites a closer look at what each card is designed to accomplish.

Where Each One Wins

The RTX 5090 Mobile wins the only direct head-to-head benchmark recorded in the database, but its advantage extends well beyond that single test. Its average benchmark score of 45152 is roughly 30% higher than the T1000's 34561 average. The RTX 5090 Mobile's percentile ranking of 84 places it above the T1000's 79, indicating a broader lead across the entire GPU landscape. In the shared Geekbench Vulkan test, the RTX 5090 Mobile scores 198405 against the T1000's 34561, a margin of 474.1%. This is not a close competition; it is a generational and architectural chasm.

The T1000's win condition is not performance but deployment. It is a single-slot, 50 W card that draws power from the slot alone, with no external power connectors. Its 156 mm length and 69 mm height make it suitable for compact workstation chassis. The RTX 5090 Mobile, by contrast, is an IGP (integrated graphics processor) soldered to a laptop motherboard, consuming 95 W. The T1000 offers four mini-DisplayPort 1.4a outputs, while the RTX 5090 Mobile's display outputs are listed as portable device dependent. For a fixed workstation with multiple monitors, the T1000's physical design is the clear advantage. The RTX 5090 Mobile wins on raw compute, memory bandwidth, and API support; the T1000 wins on form factor, power draw, and output flexibility.

Head-to-Head Benchmarks

The database contains a single head-to-head benchmark between these two GPUs: Geekbench Vulkan. The RTX 5090 Mobile posts a score of 198405, while the T1000 manages 34561. The delta of 474.1% is the defining statistic of this comparison. For context, the RTX 5090 Mobile's nearest rivals in the database are the AMD Radeon Pro 5500 XT (45384, within 0.5%), the NVIDIA GeForce RTX 4070 Ti (44795, 0.8% behind), the Intel Arc A730M (45592, 1% ahead), and the NVIDIA RTX 5880 Ada Generation (45972, 1.8% ahead). The T1000's nearest rivals are the AMD Radeon HD 7970 (34541, 0.1% behind), the NVIDIA A2 (34690, 0.4% ahead), the NVIDIA TITAN V (34355, 0.6% behind), and the NVIDIA RTX A1000 (34207, 1% behind). This placement reveals that the RTX 5090 Mobile competes with desktop-class GPUs like the RTX 4070 Ti, while the T1000 sits alongside older enthusiast cards like the TITAN V.

Beyond the head-to-head, the RTX 5090 Mobile's benchmark suite shows consistent strength. It scores 5871 in 3DMark Steel Nomad DX12, 201834 in Geekbench OpenCL, and 30034 in Passmark G3D. Its Passmark GPU Compute score is 13401. The T1000 has no recorded scores in these tests, so the comparison rests on the Vulkan result and the average scores. The RTX 5090 Mobile's 84th percentile versus the T1000's 79th percentile reinforces the gap, though the T1000's percentile is surprisingly high given its age. The T1000's average score of 34561 puts it within 1% of the AMD Radeon HD 7970 and the NVIDIA A2, indicating it still holds its own against much older or lower-tier hardware.

Specification Differences

The most obvious difference is the memory subsystem. The RTX 5090 Mobile has 24 GB of GDDR7 on a 256-bit bus, yielding 896.0 GB/s of bandwidth. The T1000 has 8 GB of GDDR6 on a 128-bit bus, yielding 160.0 GB/s. That is a 5.6x bandwidth advantage for the RTX 5090 Mobile. The compute resources follow the same pattern: the RTX 5090 Mobile has 10496 shading units, 328 TMUs, and 112 ROPs, while the T1000 has 896 shading units, 56 TMUs, and 32 ROPs. The RTX 5090 Mobile's FP32 throughput is 31.80 TFLOPS against the T1000's 2. The T1000's FP16 is 5.000 TFLOPS at a 2:1 ratio, while the RTX 5090 Mobile's FP16 is 31.80 TFLOPS at a 1:1 ratio. Clock speeds, however, tell a different story. The T1000 has a higher base clock at 1065 MHz and a boost clock of 1065 MHz, against the RTX 5090 Mobile's 990 MHz base and 1515 MHz boost. The T1000's memory clock is 1250 MHz effective at 10 Gbps, while the RTX 5090 Mobile's memory clock is 1750 MHz effective at 28 Gbps effective. The T1000 is a 50 W single-slot card measuring 156 mm in length, while the RTX 5090 Mobile is a 95 W IGP with no length listed.

The bus interface differs as well. The RTX 5090 Mobile uses PCIe 5.0 x16; the T1000 uses PCIe 3.0 x16. The T1000 lists a suggested PSU of 250 W, while the RTX 5090 Mobile has no suggested PSU listed. API support diverges at the DirectX level: the RTX 5090 Mobile offers 12 Ultimate (12_2) versus the T1000's 12 (12_1). OpenGL and Vulkan support are the same at 4.6 and 1.4 respectively.

Architecture Differences

The architectural lineage is the root of the performance gap. The RTX 5090 Mobile is built on TSMC's 5 nm process node, using the Blackwell 2.0 architecture and the GB203 chip, with 45,600 million transistors on a 378 mm die. The T1000 is built on TSMC's 12 nm process, using the Turing architecture and the TU117 chip, with 4,700 million transistors on a 200 mm die. The transistor density tells the story: 120.6 million per square mm for the RTX 5090 Mobile versus 23.5 million for the T1000. The RTX 5090 Mobile also includes 82 RT cores and 82 tensor cores, features that are entirely absent from the T1000's spec sheet. The T1000 has no RT cores and no tensor cores.

The RTX 5090 Mobile's texture rate, 496.9 GTexel/s, and pixel rate, 169.7 GPixel/s, dwarf the T1000's 78.12 GTexel/s texture rate and 44.64 GPixel/s pixel rate. The T1000's predecessor is the Quadro Volta, and its successor is Workstation Ampere. The RTX 5090 Mobile's predecessor is the GeForce 40 Mobile. The T1000 was released on 2021-05-05T17:00:00.000Z, while the RTX 5090 Mobile was released on 2025-03-26T17:00:00.000Z.

The RTX 5090 Mobile's FP32 performance is 31.80 TFLOPS, a figure that is 12.7 times higher than the T1000's 2.500 TFLOPS. The T1000's FP16 output is 5.000 TFLOPS at a 2:1 ratio, while the RTX 5090 Mobile's FP16 output is 31.80 TFLOPS at 1:1 ratio.

The Verdict

The data supports a clear conclusion: the RTX 5090 Mobile is the obvious choice for anyone needing maximum compute performance in a laptop form factor. Its 474.1% lead in Geekbench Vulkan score over the T1000, combined with 24 GB of memory, 896.0 GB/s of bandwidth, and 84th percentile ranking, makes it a top-tier option. The T1000 is for workloads that prioritize a low-power, single-slot workstation card with multiple display outputs. Its 50 W TDP and four mini-DisplayPort outputs are its defining features. The RTX 5090 Mobile is 95 W and has no fixed display outputs. The T1000 is end-of-life, while the RTX 5090 Mobile is active. The RTX 5090 Mobile is ahead in every recorded benchmark and every compute metric. The T1000 remains a viable option for legacy workstation tasks, but the data shows no scenario where it outperforms the RTX 5090 Mobile in raw performance. The RTX 5090 Mobile is the winner for compute, memory, and API support; the T1000 is the winner for physical integration and power efficiency in a desktop context.
