NVIDIA RTX A1000 Mobile vs NVIDIA RTX A2000 Comparison

The NVIDIA RTX A2000 and NVIDIA RTX A1000 Mobile are both Ampere-generation workstation GPUs, but they occupy different form factors: the A2000 is a dual-slot desktop card, while the A1000 Mobile is an integrated graphics processor for portable devices. Their average benchmark scores are nearly identical—47,915 for the A2000 versus 47,743 for the A1000 Mobile, a 0.4% gap—yet head-to-head tests reveal a much larger divide, with the A2000 leading by over 47% in both shared Geekbench workloads.

The Verdict

The data points decisively to the RTX A2000 as the stronger performer. In the two benchmarks both GPUs share—Geekbench OpenCL and Geekbench Vulkan—the A2000 wins by 50.5% and 47.7%, respectively. Its average benchmark score is also higher, though only marginally: 47,915 versus 47,743, a 0.4% edge. The A2000 additionally has a 3DMark Steel Nomad DX12 score of 1,345, which the A1000 Mobile does not have, so no comparison exists there. For any workload that stresses raw compute, the A2000 is the clear choice. The A1000 Mobile, however, is an IGP with a lower 60 W TDP and no display outputs of its own—it depends on the host portable device. The verdict is straightforward: if you need a discrete workstation card with dedicated outputs, the A2000 wins outright. If you require a low-power mobile solution, the A1000 Mobile is the only option, but the data shows it trails significantly in compute. Both GPUs are end-of-life, and the A2000 had a launch MSRP of 449 USD.

Architecture Differences

Both GPUs use the same 8 nm Samsung process and have identical transistor density of 43.5M per mm². The chips differ: the A2000 uses GA106 with 12,000 million transistors on a 276 mm² die, while the A1000 Mobile uses GA107 with 8,700 million transistors on a 200 mm² die. The A2000 has 3,328 shading units, 104 TMUs, 48 ROPs, 26 RT cores, and 104 tensor cores. The A1000 Mobile has 2,048 shading units, 64 TMUs, 32 ROPs, 16 RT cores, and 64 tensor cores. Memory also diverges: the A2000 has 6 GB GDDR6 on a 192-bit bus with 288.0 GB/s bandwidth, while the A1000 Mobile has 4 GB GDDR6 on a 128-bit bus with 176.0 GB/s. Clock speeds differ: the A2000 runs at 562 MHz base and 1200 MHz boost; the A1000 Mobile runs at 630 MHz base and 1140 MHz boost. Memory clocks are 1500 MHz (12 Gbps effective) for the A2000 and 1375 MHz (11 Gbps) for the A1000 Mobile. The A2000 has a 70 W TDP and is dual-slot with four mini-DisplayPort 1.4a outputs; the A1000 Mobile is an IGP with a 60 W TDP and "Portable Device Dependent" display outputs. The bus interface differs: PCIe 4.0 x16 for the A2000 versus x8 for the A1000 Mobile. The A2000 lists a suggested PSU of 250 W; the A1000 Mobile has none. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The two GPUs share exactly two benchmark results: Geekbench OpenCL and Geekbench Vulkan. In OpenCL, the A2000 scores 73,310 while the A1000 Mobile scores 48,703, a delta of 50.5% in favor of the A2000. In Vulkan, the A2000 scores 69,089 against 46,782, a 47.7% lead. These are substantial gaps. The average benchmark scores, however, are much closer—47,915 versus 47,743, a 0.4% difference—which suggests that the average includes workloads where the A1000 Mobile performs relatively better, or that the Geekbench compute tests heavily favor the A2000's higher core counts and memory bandwidth. The A2000 also has a 3DMark Steel Nomad DX12 score of 1,345, but the A1000 Mobile has no corresponding result, so no direct comparison is possible. The data clearly shows the A2000 winning every shared test. For context, the A2000 is 0.4% ahead of the A1000 Mobile in average score, but 1.6% behind the GeForce RTX 4070 Ti SUPER and 2.4% behind the CMP 50HX, while being 2.8% ahead of the Intel Arc A530M. The A1000 Mobile is 2% behind the RTX 4070 Ti SUPER, 2.4% ahead of the Arc A530M, and 2.6% ahead of the AMD Radeon RX 6550M. This places both GPUs in a similar performance tier, but the A2000 consistently edges ahead in the shared tests.
