NVIDIA GeForce RTX 3080 Ti vs NVIDIA RTX A1000 Comparison

Where Each One Wins

The data splits these two Ampere cards into entirely different use cases, and the benchmark results make that split obvious. The NVIDIA GeForce RTX 3080 Ti wins all three recorded head-to-head tests, and it wins them by margins that are not close. In 3DMark Steel Nomad DX12, the RTX 3080 Ti scores 5077 against the RTX A1000's 969, a 423.9% advantage. In Geekbench OpenCL, the RTX 3080 Ti posts 170037 versus 52078, a 226.5% lead. In Geekbench Vulkan, the RTX 3080 Ti reaches 192697 while the RTX A1000 manages 49574, a 288.7% gap. If raw performance is the requirement, the RTX 3080 Ti is the only choice between these two.

The RTX A1000, however, is not designed to compete on raw frame rates or compute throughput. Its wins are structural, not numerical. It is a single-slot card with no power connectors, a 50 W TDP, and a 250 W suggested PSU, versus the RTX 3080 Ti's dual-slot footprint, 1x 12-pin connector, 350 W TDP, and 750 W suggested PSU. The RTX A1000 measures 163 mm in length and 69 mm in height, while the RTX 3080 Ti stretches to 285 mm in length and 112 mm in height. For dense workstation builds, multi-GPU rigs, or systems where space and power delivery are constrained, the RTX A1000 fits where the RTX 3080 Ti physically cannot. It also outputs 4x mini-DisplayPort 1.4a, which suits multi-monitor professional setups, while the RTX 3080 Ti offers 1x HDMI 2.1 and 3x DisplayPort 1.4a.

The RTX A1000 is also an active production card with a 2024 release date, whereas the RTX 3080 Ti is marked end-of-life with a 2021 launch. The A1000's predecessor is Quadro Turing, and its successor is Workstation Ada, placing it in a long-lived professional line. The RTX 3080 Ti sits between GeForce 20 and GeForce 40 as a consumer flagship. For buyers who need current driver support and a card that is still being manufactured, the RTX A1000 has the lifecycle advantage. For anyone who needs compute results, the RTX 3080 Ti is overwhelmingly faster, but the A1000 wins on integration ease, power budget, and availability.

The Verdict

Pick the NVIDIA GeForce RTX 3080 Ti if your workload is performance-bound and your chassis can handle a 285 mm dual-slot card with a 350 W TDP and a 750 W suggested PSU. The recorded data shows it is 423.9% ahead in 3DMark Steel Nomad DX12, 226.5% ahead in Geekbench OpenCL, and 288.7% ahead in Geekbench Vulkan. Its average benchmark score across all recorded tests is 41187, placing it in the 83rd percentile of all GPUs. Its nearest rivals include the AMD Radeon Pro 5300 at 40870 (0.8% behind), the NVIDIA Tesla M40 24 GB at 41707 (1.2% ahead), and the NVIDIA GeForce RTX 5070 at 40377 (2% behind). That places the RTX 3080 Ti in solidly capable territory, trading blows with cards from different generations and markets.

Pick the NVIDIA RTX A1000 if your priority is a low-power, single-slot, professional card that runs off the slot alone with no external power. Its 50 W TDP and 250 W suggested PSU make it trivial to integrate into existing workstations. Its average benchmark score is 34207, which puts it in the 79th percentile of all GPUs, and its nearest rivals are the NVIDIA RTX A2000 12 GB at 34154 (0.2% behind), the AMD Radeon RX 560 XT at 34133 (0.2% behind), and the AMD Radeon RX 480 at 33997 (0.6% behind). The RTX A1000 is within 0.2% of the RTX A2000 12 GB, which is a strong result for a card with only 8 GB of memory and a 128-bit bus. The A1000 also has a 2024 release date and active production status, so it is a current product with a clear roadmap.

The verdict is simple. If you are building or upgrading a system where every watt and every millimeter counts, the RTX A1000 is the measured choice. If you need the fastest possible results in the recorded benchmarks, the RTX 3080 Ti wins outright, and the data does not suggest any scenario where the A1000 closes that gap.

Head-to-Head Benchmarks

The head-to-head table in the database contains three tests, and the RTX 3080 Ti wins all three. The largest margin is in 3DMark Steel Nomad DX12, where the RTX 3080 Ti scores 5077 and the RTX A1000 scores 969. That is a 423.9% delta, meaning the RTX 3080 Ti delivers over five times the performance in that DirectX 12 workload. This test stresses modern rendering features, and the RTX 3080 Ti's 10240 shading units, 80 RT cores, and 912.4 GB/s of memory bandwidth are far beyond the A1000's 2304 shading units, 18 RT cores, and 192.0 GB/s bandwidth.

In Geekbench Vulkan, the RTX 3080 Ti scores 192697 versus 49574, a 288.7% delta. Vulkan is a low-level API that rewards raw throughput, and the RTX 3080 Ti's 34.10 TFLOPS FP32 and FP16 performance dwarf the A1000's 6.737 TFLOPS in both. The RTX 3080 Ti also has 320 tensor cores versus 72, and 320 TMUs versus 72, so texture-heavy and compute-heavy workloads scale accordingly.

In Geekbench OpenCL, the RTX 3080 Ti scores 170037 against 52078, a 226.5% delta. OpenCL is commonly used in professional compute tasks, and the RTX 3080 Ti's larger die, 28,300 million transistors on a 628 mm² chip, versus the A1000's 8,700 million transistors on a 200 mm² chip, explains the gap. The RTX 3080 Ti's pixel rate is 186.5 GPixel/s versus 46.78 GPixel/s, and its texture rate is 532.8 GTexel/s versus 105.3 GTexel/s. Every measured throughput metric favors the RTX 3080 Ti by a wide margin.

The RTX A1000 does have one notable structural advantage in the benchmark context: its single-slot, 50 W design means it can be deployed in systems where the RTX 3080 Ti would require a PSU upgrade and a larger chassis. But in the actual recorded scores, there is no test where the A1000 comes within a meaningful distance. The closest delta is the 226.5% OpenCL result, which is still more than triple the A1000's score. The database shows 3 wins for the RTX 3080 Ti and 0 for the RTX A1000, and that record is consistent across every metric recorded.

Architecture Differences

Both cards use the Ampere architecture, but they are built on different chips with very different scales. The RTX 3080 Ti uses the GA102 chip, while the RTX A1000 uses the GA107. Both are fabricated on an 8 nm process at Samsung, but the GA102 packs 28,300 million transistors on a 628 mm² die, giving a transistor density of 45.1M per mm². The GA107 is far smaller at 8,700 million transistors on a 200 mm² die, with a density of 43.5M per mm². The RTX 3080 Ti's die is more than three times larger and holds more than three times the transistors.

The compute resources diverge sharply. The RTX 3080 Ti has 10240 shading units, 320 TMUs, 112 ROPs, 80 RT cores, and 320 tensor cores. The RTX A1000 has 2304 shading units, 72 TMUs, 32 ROPs, 18 RT cores, and 72 tensor cores. That is a 4.4x difference in shading units, a 4.4x difference in TMUs, a 3.5x difference in ROPs, a 4.4x difference in RT cores, and a 4.4x difference in tensor cores. The RTX 3080 Ti's FP32 rating is 34.10 TFLOPS, and its FP16 rating is 34.10 TFLOPS at a 1:1 ratio. The RTX A1000's FP32 is 6.737 TFLOPS, and its FP16 is also 6.737 TFLOPS at 1:1.

Both cards support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 3080 Ti uses a PCIe 4.0 x16 interface, while the RTX A1000 uses PCIe 4.0 x8. The memory subsystems are entirely different: the RTX 3080 Ti runs 12 GB of GDDR6X at 19 Gbps effective on a 384-bit bus, delivering 912.4 GB/s. The RTX A1000 runs 8 GB of GDDR6 at 12 Gbps effective on a 128-bit bus, delivering 192.0 GB/s. The RTX 3080 Ti's pixel rate is 186.5 GPixel/s and its texture rate is 532.8 GTexel/s, versus the A1000's 46.78 GPixel/s and 105.3 GTexel/s.

The generations differ as well. The RTX 3080 Ti belongs to the GeForce 30-series, with its predecessor being GeForce 20 and its successor GeForce 40. The RTX A1000 belongs to the Workstation Ampere (Ax000) generation, with its predecessor being Quadro Turing and its successor Workstation Ada. Both are NVIDIA products, but the RTX 3080 Ti is a consumer gaming/enthusiast card, while the RTX A1000 is a professional workstation card.
