NVIDIA RTX A1000 Mobile vs NVIDIA T1000 Comparison

Head-to-Head Benchmarks

The recorded data shows a clear and consistent advantage for the NVIDIA RTX A1000 Mobile across both benchmark tests. In Geekbench OpenCL, the RTX A1000 Mobile scores 48,703, while the NVIDIA T1000 manages 37,704. That is a 29.2% lead for the Ampere-based mobile part. The gap widens further in Geekbench Vulkan, where the RTX A1000 Mobile posts 46,782 against the T1000's 34,874. That translates to a 34.1% advantage, making the Vulkan result the single biggest margin in this comparison.

The average benchmark score reinforces the pattern. The RTX A1000 Mobile sits at 47,743, while the T1000 trails at 36,289. That is a difference of roughly 11,454 points, or about 31.6% in favor of the RTX A1000 Mobile. The percentile rankings also separate the two: the RTX A1000 Mobile lands in the 85th percentile of all GPUs, while the T1000 sits in the 80th percentile. A five-percentile gap is meaningful, especially when both cards target professional workloads rather than gaming.

Looking at the nearest rivals in the database adds context. The RTX A1000 Mobile's average score of 47,743 places it just 1.5% behind the AMD Radeon RX 6800 XT, which averages 48,477. It also leads the AMD Radeon RX 6550M by 2.2%, the Intel Arc A530M by 2.4%, and the AMD Radeon RX 5600M by 2.5%. Those are tight margins, indicating that the RTX A1000 Mobile competes at a higher performance tier than its modest TDP might suggest.

The T1000, by contrast, sits in different company. Its average score of 36,289 is within 0.7% of both the AMD Radeon RX 5300M and the NVIDIA GeForce GTX TITAN X, the latter scoring 36,530. The T1000 edges out the AMD Radeon Pro Duo by 1.2% and the NVIDIA Quadro GV100 by 2.2%. These rivals are older or lower-tier parts, which tells you exactly where the T1000 sits in the performance hierarchy: it is a capable entry-level workstation card, but not a high-throughput compute part.

Where Each One Wins

The win tally is lopsided: the RTX A1000 Mobile takes both head-to-head benchmarks, while the T1000 secures zero. But the data supports a more nuanced use-case split than just "the newer card is faster." The RTX A1000 Mobile wins on raw compute throughput, especially in Vulkan, where its 34.1% lead suggests better driver optimization for modern APIs. The T1000, despite losing both tests, still has strengths that matter in specific professional scenarios.

The RTX A1000 Mobile's advantage comes from its Ampere architecture. It has 2,048 shading units, 64 texture mapping units, 32 ROPs, 16 ray tracing cores, and 64 tensor cores. Its FP32 throughput is rated at 4.669 TFLOPS, and its FP16 output matches that at a 1:1 ratio. The T1000, built on Turing, offers 896 shading units, 56 TMUs, and 32 ROPs, but has no dedicated ray tracing or tensor cores. Its FP32 rating is 2.500 TFLOPS, and while its FP16 reaches 5.000 TFLOPS, that comes at a 2:1 ratio, meaning it is not a true full-rate FP16 part.

Where the T1000 does hold ground is in pixel and texture throughput. Its pixel rate is 44.64 GPixel/s, which is 22.4% higher than the RTX A1000 Mobile's 36.48 GPixel/s. Its texture rate of 78.12 GTexel/s also edges out the RTX A1000 Mobile's 72.96 GTexel/s by about 7.1%. These numbers suggest that for certain rasterization-heavy workloads that depend on fill rate rather than shader complexity, the T1000 can keep up or even surpass the RTX A1000 Mobile, despite its lower overall compute scores.

Memory bandwidth is another split. The RTX A1000 Mobile uses 11 Gbps effective GDDR6 on a 128-bit bus, yielding 176.0 GB/s. The T1000 uses 10 Gbps effective memory on the same 128-bit bus, producing 160.0 GB/s. The RTX A1000 Mobile leads by 10%, which matters for large datasets and texture-heavy scenes. Both cards have 4 GB of memory, so capacity is not a differentiator.

The RTX A1000 Mobile also supports DirectX 12 Ultimate with feature level 12_2, while the T1000 only reaches DirectX 12 with feature level 12_1. That means the RTX A1000 Mobile can handle newer rendering features like mesh shaders and variable rate shading, which the T1000 cannot. For Vulkan and OpenGL, both support version 1.4 and 4.6 respectively, so no gap there.

The Verdict

The data points to a straightforward conclusion: the NVIDIA RTX A1000 Mobile is the stronger card in almost every measurable way. It wins both benchmark tests, has a higher average score, sits in a higher percentile, and offers more modern architecture features. The 29.2% lead in OpenCL and 34.1% lead in Vulkan are not marginal differences; they represent a full performance tier of separation.

Choose the RTX A1000 Mobile if your work is compute-bound, uses modern APIs, or benefits from tensor and ray tracing hardware. Its 4.669 TFLOPS of FP32 performance and full-rate FP16 capability make it the better choice for machine learning inference, ray-traced rendering, and any workload that can leverage the 64 tensor cores. The 16 ray tracing cores are a bonus that the T1000 simply does not have.

Choose the T1000 only if your specific application is fill-rate limited and you need the higher pixel or texture throughput. The T1000's 44.64 GPixel/s pixel rate and 78.12 GTexel/s texture rate are genuinely higher than the RTX A1000 Mobile's. For 2D CAD, some GIS tasks, or legacy OpenGL applications that hammer the rasterizer, the T1000 might perform adequately. It also runs at a lower 50 W TDP versus 60 W, which can matter in tight thermal envelopes.

However, the T1000 is a Turing-era part with no RT or tensor cores, a 12 nm process, and only PCIe 3.0 x16 connectivity. The RTX A1000 Mobile uses an 8 nm Samsung process, PCIe 4.0 x8, and supports more modern features. The T1000 was released on 2021-05-05, while the RTX A1000 Mobile came later on 2022-03-29. Both are end-of-life, but the RTX A1000 Mobile is the more future-proof option.

For most buyers, the RTX A1000 Mobile is the obvious pick. The T1000's fill-rate advantages are narrow and unlikely to outweigh the massive compute deficit. If you need a low-profile, single-slot workstation card with 4x mini-DisplayPort outputs, the T1000 has that specific form factor advantage. But if performance is the priority, the RTX A1000 Mobile wins decisively.

A: The RTX A1000 Mobile includes 16 ray tracing cores and 64 tensor cores, while the T1000 has neither. The RTX A1000 Mobile also supports DirectX 12 Ultimate (12_2), whereas the T1000 only supports DirectX 12 (12_1).

Q: Which GPU has a higher transistor count?

A: The RTX A1000 Mobile uses a GA107 chip with 8,700 million transistors on an 8 nm Samsung process. The T1000 uses a TU117 chip with 4,700 million transistors on a 12 nm TSMC process. Both have the same 200 mm² die size.

Architecture Differences

The RTX A1000 Mobile is built on the Ampere architecture using the GA107 chip, fabricated by Samsung on an 8 nm process. The T1000 uses the Turing architecture with the TU117 chip, fabricated by TSMC on a 12 nm process. This process difference is significant: the 8 nm node allows the RTX A1000 Mobile to pack 8,700 million transistors into the same 200 mm² die size as the T1000, which contains only 4,700 million transistors. That yields a transistor density of 43.5M per mm² for the RTX A1000 Mobile versus 23.5M per mm² for the T1000.

The compute resources diverge sharply. The RTX A1000 Mobile has 2,048 shading units, 64 TMUs, 32 ROPs, 16 ray tracing cores, and 64 tensor cores. The T1000 has 896 shading units, 56 TMUs, and 32 ROPs, but no RT or tensor cores. This means the RTX A1000 Mobile can handle ray-traced workloads and tensor-based operations, while the T1000 is purely a rasterization and compute part.

Clock speeds also differ. The RTX A1000 Mobile runs at a 630 MHz base and 1140 MHz boost, while the T1000 runs at 1065 MHz base and 1395 MHz boost. Despite the T1000's higher clocks, the RTX A1000 Mobile's shader count advantage overwhelms the frequency gap. The RTX A1000 Mobile's FP32 throughput is 4.669 TFLOPS versus 2.500 TFLOPS for the T1000. In FP16, the RTX A1000 Mobile matches its FP32 at 4.669 TFLOPS (1:1 ratio), while the T1000 reaches 5.000 TFLOPS but only at a 2:1 ratio, meaning it is not true full-rate FP16.

Both GPUs support OpenGL 4.6 and Vulkan 1.4, but their DirectX support differs. The RTX A1000 Mobile supports DirectX 12 Ultimate with feature level 12_2, while the T1000 stops at DirectX 12 with feature level 12_1. The RTX A1000 Mobile also uses a PCIe 4.0 x8 interface, while the T1000 uses PCIe 3.0 x16. The newer PCIe 4.0 standard offers higher per-lane bandwidth, though the T1000 has twice the lane count.
