NVIDIA GeForce RTX 5090 Mobile vs NVIDIA T1000 Comparison

Head-to-Head Benchmarks

The recorded data leaves no ambiguity: the NVIDIA GeForce RTX 5090 Mobile dominates the NVIDIA T1000 in every available head-to-head comparison. Two benchmark tests were conducted, and the RTX 5090 Mobile won both by overwhelming margins.

In Geekbench OpenCL, the RTX 5090 Mobile scores 201,834 points against the T1000's 37,704 points. This represents a 435.3% advantage for the newer mobile part. The gap is so large that the T1000's score is less than one-fifth of the RTX 5090 Mobile's output. The Geekbench Vulkan test tells a similar story, with the RTX 5090 Mobile posting 198,405 points versus 34,874 points for the T1000, a 468.9% difference. The Vulkan delta is even larger than the OpenCL gap, suggesting the RTX 5090 Mobile's architecture scales particularly well with modern graphics APIs.

These results place the RTX 5090 Mobile in the 84th percentile of all GPUs in the database, while the T1000 sits in the 80th percentile. The percentile difference is relatively modest despite the massive score gap, indicating that the T1000 still outperforms a large portion of the GPU landscape, but the sheer distance between these two specific products is unmistakable.

The average benchmark score reinforces the hierarchy. The RTX 5090 Mobile averages 45,152 points, while the T1000 averages 36,289 points. That is a difference of 8,863 points, or roughly 24.4% on average. The RTX 5090 Mobile's nearest rivals in the database include the AMD Radeon Pro 5500 XT (45,384, just 0.5% higher), the NVIDIA GeForce RTX 4070 Ti (44,795, 0.8% lower), the Intel Arc A730M (45,592, 1% lower), and the NVIDIA RTX 5880 Ada Generation (45,972, 1.8% lower). The T1000's nearest rivals are the AMD Radeon RX 5300M (36,529, 0.7% lower), the NVIDIA GeForce GTX TITAN X (36,530, 0.7% lower), the AMD Radeon Pro Duo (35,860, 1.2% higher), and the NVIDIA Quadro GV100 (35,520, 2.2% higher). This means the RTX 5090 Mobile competes in a completely different performance tier than the T1000, sitting among modern high-end desktop and workstation GPUs.

Where Each One Wins

The RTX 5090 Mobile wins every benchmark category where both products have recorded data. In compute workloads, the OpenCL result demonstrates a 435.3% advantage, which translates to roughly 5.4 times the raw compute throughput. For graphics workloads, the Vulkan result shows a 468.9% advantage, meaning the RTX 5090 Mobile delivers nearly 5.7 times the graphics performance in that test.

The T1000 has no recorded wins in the database. However, it does have strengths that are not captured in head-to-head benchmark scores. The T1000 is a single-slot, low-profile card with a 50 W TDP, making it appropriate for compact workstations where space and power are constrained. It draws power through the PCIe slot with no additional power connectors, simplifying installation. The card measures 156 mm in length and 69 mm in height, allowing it to fit in small form factor chassis. Its 4 GB of GDDR6 memory on a 128-bit bus provides 160.0 GB/s of bandwidth, which is sufficient for legacy professional applications that do not demand large frame buffers.

The RTX 5090 Mobile, by contrast, is an integrated graphics processor designed for laptops and portable devices. It has no fixed dimensions or display outputs, as those depend on the host device. It requires no power connectors and has a 95 W TDP, which is higher than the T1000 but still modest for a GPU with 24 GB of GDDR7 memory. The RTX 5090 Mobile's 896.0 GB/s of memory bandwidth is 5.6 times that of the T1000, which directly contributes to its massive performance lead in memory-intensive workloads.

Architecture Differences

The two GPUs come from entirely different generations and design philosophies. The RTX 5090 Mobile uses the GB203 chip built on the Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process. The T1000 uses the TU117 chip built on the Turing architecture, also fabricated by TSMC but on a 12 nm process. The process node difference is substantial: 5 nm versus 12 nm, which explains the massive transistor density gap. The RTX 5090 Mobile packs 45,600 million transistors into a 378 mm² die, achieving 120.6 million transistors per square millimeter. The T1000 has 4,700 million transistors on a 200 mm² die, for a density of 23.5 million transistors per square millimeter. The RTX 5090 Mobile has nearly 10 times the transistor count and over 5 times the density.

The compute resources diverge sharply. The RTX 5090 Mobile has 10,496 shading units, 328 texture mapping units, and 112 raster output units. The T1000 has 896 shading units, 56 TMUs, and 32 ROPs. The RTX 5090 Mobile also features 82 ray tracing cores and 328 tensor cores, while the T1000 has none of either. This means the RTX 5090 Mobile supports hardware-accelerated ray tracing and AI workloads, while the T1000 does not. The pixel rate of the RTX 5090 Mobile is 169.7 GPixel/s versus 44.64 GPixel/s for the T1000, and the texture rate is 496.9 GTexel/s versus 78.12 GTexel/s.

Memory technology also differs. The RTX 5090 Mobile uses 24 GB of GDDR7 memory on a 256-bit bus, while the T1000 uses 4 GB of GDDR6 on a 128-bit bus. The RTX 5090 Mobile's memory clock is 1750 MHz, which translates to 28 Gbps effective, while the T1000 runs at 1250 MHz, or 10 Gbps effective. The bandwidth figures are 896.0 GB/s versus 160.0 GB/s. The FP32 compute performance is 31.80 TFLOPS for the RTX 5090 Mobile versus 2.500 TFLOPS for the T1000. The FP16 performance differs in ratio: the RTX 5090 Mobile achieves 31.80 TFLOPS with a 1:1 ratio, while the T1000 achieves 5.000 TFLOPS with a 2:1 ratio.

The bus interface also differs: the RTX 5090 Mobile uses PCIe 5.0 x16, while the T1000 uses PCIe 3.0 x16. The API support shows the RTX 5090 Mobile supports DirectX 12 Ultimate (12_2), while the T1000 only supports DirectX 12 (12_1). Both support OpenGL 4.6 and Vulkan 1.4. The T1000 has four mini-DisplayPort 1.4a outputs, while the RTX 5090 Mobile's display outputs are dependent on the portable device it is integrated into.

The Verdict

The data supports a decisive conclusion: the NVIDIA GeForce RTX 5090 Mobile is the superior GPU in nearly every measurable way. It wins all head-to-head benchmarks with deltas exceeding 435%, offers 6 times the memory capacity, 5.6 times the memory bandwidth, and 12.7 times the FP32 compute throughput. It also adds hardware ray tracing and tensor cores, neither of which the T1000 possesses. The RTX 5090 Mobile is in the 84th percentile of all GPUs, while the T1000 sits in the 80th percentile, and the RTX 5090 Mobile's nearest rivals include desktop-class GPUs like the RTX 4070 Ti and RTX 5880 Ada Generation.

The T1000 does have one clear advantage: efficiency and form factor. Its 50 W TDP is roughly half of the RTX 5090 Mobile's 95 W, and its single-slot design with four mini-DisplayPort outputs makes it suitable for legacy multi-display workstation setups in compact chassis. The T1000 is also end-of-life, with a successor in Workstation Ampere, so new deployments should look elsewhere.

The RTX 5090 Mobile is the clear choice for anyone needing maximum performance in a portable form factor. Its 24 GB frame buffer and Blackwell 2.0 architecture make it suitable for modern AI workloads, ray-traced rendering, and high-resolution content creation. The T1000 remains viable only for low-power, space-constrained applications where its 4 GB of memory and 2.5 TFLOPS of compute are sufficient. For any workload that demands modern graphics features or significant compute throughput, the RTX 5090 Mobile is the only rational pick based on the recorded data.
