NVIDIA GeForce RTX 4080 Mobile vs NVIDIA T1000 8 GB Comparison

Where Each One Wins

The benchmark data paints a starkly lopsided picture. The NVIDIA GeForce RTX 4080 Mobile wins the only shared benchmark test — Geekbench Vulkan — with a score of 145,807 against the NVIDIA T1000 8 GB’s 34,561. That is a 321.9% advantage, meaning the RTX 4080 Mobile delivers over four times the Vulkan performance of the T1000 8 GB. In this specific test, there is no contest.

However, the data also reveals that the T1000 8 GB is not without its niche. Its average benchmark score of 34,561 places it in the 79th percentile of all GPUs, while the RTX 4080 Mobile sits at the 81st percentile. The percentile gap is only 2 points, suggesting that despite the massive Vulkan delta, the T1000 8 GB remains competitive in the broader GPU landscape for its intended use cases. The T1000 8 GB’s nearest rivals include the AMD Radeon HD 7970 (0.1% higher) and the NVIDIA TITAN V (0.6% higher), indicating it holds its own against much older flagship hardware.

The RTX 4080 Mobile’s wins extend beyond Vulkan. Its benchmark suite includes Geekbench OpenCL (159,575), Passmark DirectX 10 (157), DirectX 11 (244), DirectX 12 (96), DirectX 9 (286), G2D (929), G3D (24,926), and GPU Compute (11,191). The T1000 8 GB has no scores for any of these tests in the data pack, meaning the RTX 4080 Mobile wins every category where a direct comparison exists. The T1000 8 GB simply cannot match the sheer compute throughput of the RTX 4080 Mobile across the board.

That said, the T1000 8 GB’s single-slot design and 50 W TDP suggest a different priority: low-profile, low-power workstation duty. The RTX 4080 Mobile is an IGP (integrated graphics processor) with a 110 W TDP, while the T1000 8 GB is a single-slot card with no power connectors and a suggested 250 W PSU. The data implies the T1000 8 GB wins on efficiency and form factor, even if it loses decisively on raw performance.

Head-to-Head Benchmarks

The only head-to-head benchmark available is Geekbench Vulkan, and it is a rout. The RTX 4080 Mobile scores 145,807, while the T1000 8 GB scores 34,561. This yields a delta of 321.9%, meaning the RTX 4080 Mobile is approximately 4.2 times faster in this specific workload. The Vulkan API is commonly used for cross-platform compute and gaming, so this result indicates a massive advantage in modern graphics and compute tasks.

Beyond the direct comparison, the RTX 4080 Mobile’s other benchmark scores provide context. Its Passmark G3D score of 24,926 and GPU Compute score of 11,191 are strong indicators of general 3D rendering and compute performance. The T1000 8 GB has no such data, so extrapolation is impossible. However, the T1000 8 GB’s average score of 34,561 is only 9.4% lower than the RTX 4080 Mobile’s average of 38,135, which suggests that in aggregate workloads, the gap narrows considerably compared to the Vulkan test.

The RTX 4080 Mobile’s nearest rivals include the NVIDIA GeForce RTX 4070 (1.3% higher average score) and the NVIDIA Tesla P4 (1.3% higher). This places the RTX 4080 Mobile in the same performance class as desktop mid-range GPUs, despite being a mobile part. The T1000 8 GB, by contrast, sits near the NVIDIA RTX A1000 (1% higher) and NVIDIA A2 (0.4% lower), indicating it is closer to entry-level workstation GPUs.

Specification Differences

The two GPUs differ fundamentally in nearly every specification. The RTX 4080 Mobile uses a 5 nm process node from TSMC, while the T1000 8 GB uses a 12 nm node. The RTX 4080 Mobile packs 35,800 million transistors on a 294 mm² die, whereas the T1000 8 GB has 4,700 million transistors on a 200 mm² die. Transistor density is 121.8M per mm² for the RTX 4080 Mobile versus 23.5M per mm² for the T1000 8 GB.

Memory configurations diverge sharply. The RTX 4080 Mobile has 12 GB of GDDR6 on a 192-bit bus, delivering 432.0 GB/s bandwidth. The T1000 8 GB has 8 GB of GDDR6 on a 128-bit bus, with 160.0 GB/s bandwidth. Clock speeds also differ: the RTX 4080 Mobile runs at 1290 MHz base and 1665 MHz boost, while the T1000 8 GB runs at 1065 MHz base and 1395 MHz boost. Memory clocks are 2250 MHz (18 Gbps effective) for the RTX 4080 Mobile and 1250 MHz (10 Gbps effective) for the T1000 8 GB.

Compute resources are vastly different. The RTX 4080 Mobile has 7,424 shading units, 232 TMUs, 80 ROPs, 58 RT cores, and 232 tensor cores. The T1000 8 GB has 896 shading units, 56 TMUs, 32 ROPs, and no RT or tensor cores. The RTX 4080 Mobile achieves 24.72 TFLOPS FP32, while the T1000 8 GB manages 2.500 TFLOPS FP32. FP16 performance is 24.72 TFLOPS (1:1) for the RTX 4080 Mobile and 5.000 TFLOPS (2:1) for the T1000 8 GB.

Power and physical specs differ too. The RTX 4080 Mobile is an IGP with a 110 W TDP and no power connectors. The T1000 8 GB is a single-slot card with a 50 W TDP, no power connectors, and a suggested 250 W PSU. The T1000 8 GB measures 156 mm (6.1 inches) in length and 69 mm (2.7 inches) in height, while the RTX 4080 Mobile has no listed dimensions. The RTX 4080 Mobile uses PCIe 4.0 x16, while the T1000 8 GB uses PCIe 3.0 x16. Display outputs are portable-device-dependent for the RTX 4080 Mobile, versus 4x mini-DisplayPort 1.4a for the T1000 8 GB.

Architecture Differences

The architectural gap is generational. The RTX 4080 Mobile is built on NVIDIA’s Ada Lovelace architecture, the same found in the GeForce 40-series. It uses the AD104 chip and supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The T1000 8 GB is based on the older Turing architecture, using the TU117 chip from the Quadro Turing (Tx000) generation. It supports DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4 — notably missing the “Ultimate” designation, which implies less advanced ray tracing and mesh shading features.

The presence of RT cores and tensor cores in the RTX 4080 Mobile (58 and 232, respectively) is a defining difference. The T1000 8 GB has neither, meaning it lacks dedicated hardware for ray tracing and AI acceleration. This makes the RTX 4080 Mobile far more capable for modern workloads that leverage these features, such as real-time ray tracing, DLSS, and machine learning inference.

Process technology is also a differentiator. The RTX 4080 Mobile’s 5 nm node from TSMC is a significant advancement over the T1000 8 GB’s 12 nm node, contributing to higher transistor density and better power efficiency per transistor. The RTX 4080 Mobile’s FP16 performance is listed as 1:1 with FP32, whereas the T1000 8 GB’s FP16 is 2:1, meaning the RTX 4080 Mobile handles half-precision workloads at full rate, a key advantage for AI and compute tasks.

The RTX 4080 Mobile is part of the GeForce 40 Mobile generation, with a release date of 2023-01-02, while the T1000 8 GB was released on 2021-05-05 in the Quadro Turing lineup. The RTX 4080 Mobile’s predecessor is GeForce 30 Mobile, and its successor is GeForce 50 Mobile. The T1000 8 GB’s predecessor is Quadro Volta, and its successor is Workstation Ampere. Production status also differs: the RTX 4080 Mobile is Active, while the T1000 8 GB is End-of-life.

The Verdict

The data is unambiguous for raw performance: the NVIDIA GeForce RTX 4080 Mobile is in a different class. It wins the only shared benchmark by 321.9%, has a higher average score (38,135 vs. 34,561), and offers more memory, bandwidth, and compute resources. Anyone needing maximum graphics and compute throughput should choose the RTX 4080 Mobile, provided the laptop form factor and 110 W TDP are acceptable.

The NVIDIA T1000 8 GB, however, is not without merit. It is a single-slot, 50 W card that requires no external power and fits in a compact 156 mm length. It supports four mini-DisplayPort outputs, making it suitable for multi-display workstation setups. Its 79th percentile ranking shows it is still a capable performer for its class, but it lacks RT cores, tensor cores, and the architectural features of Ada Lovelace.

The choice hinges on workload. For gaming, ray tracing, AI, or any modern compute task, the RTX 4080 Mobile is the obvious pick. For a low-power, small-form-factor workstation that drives multiple displays and handles legacy or light 3D workloads, the T1000 8 GB remains a viable option. The benchmark data cannot justify the T1000 8 GB on performance alone, but its physical and power characteristics might make it the right tool for constrained environments.
