NVIDIA RTX A1000 Mobile vs NVIDIA RTX A3000 Mobile Comparison

Where Each One Wins

The benchmark data is unambiguous: the NVIDIA RTX A3000 Mobile wins both recorded head-to-head tests against the NVIDIA RTX A1000 Mobile. That means the A3000 Mobile takes the openCL and Vulkan workloads, while the A1000 Mobile has no wins in the database. For use-case planning, this splits cleanly. The A3000 Mobile is the choice for compute-heavy tasks that stress OpenCL, which tends to cover scientific, engineering, and rendering workloads. The Vulkan win matters for graphics APIs used in modern game engines and real-time visualization. The A1000 Mobile, by contrast, does not win anywhere in the recorded data, so it cannot be recommended for any workload where the A3000 Mobile is an option.

The average benchmark scores reinforce this. The A3000 Mobile posts an average of 70140 across its tests, while the A1000 Mobile averages 47743. That is a substantial gap, roughly a 47% difference in favor of the A3000 Mobile. The percentile placement also differs. The A3000 Mobile sits at the 91st percentile of all GPUs, while the A1000 Mobile sits at the 85th. So the A3000 Mobile is not merely faster, it belongs to a higher performance tier overall.

Architecture Differences

Both GPUs share the same Ampere architecture, the same 8 nm Samsung process, and the same generation label, Ampere-MW (Ax000). The differences start with the chip. The A3000 Mobile uses GA104, while the A1000 Mobile uses GA107. That is a meaningful distinction because GA104 is a larger die. The A3000 Mobile contains 17,400 million transistors on a 392 mm² die, while the A1000 Mobile contains 8,700 million transistors on a 200 mm² die. Transistor density is nearly identical, at 44.4M per mm² for the A3000 Mobile and 43.5M per mm² for the A1000 Mobile, which makes sense since both come from the same foundry and process.

The execution resources scale accordingly. The A3000 Mobile has 4096 shading units, 128 texture mapping units, and 64 ROPs. The A1000 Mobile has half of each: 2048 shading units, 64 TMUs, and 32 ROPs. Ray tracing cores follow the same pattern, 32 versus 16, and tensor cores double as well, 128 versus 64. The memory subsystem also differs. The A3000 Mobile has 6 GB of GDDR6 on a 192 bit bus, delivering 264.0 GB/s of bandwidth. The A1000 Mobile has 4 GB of GDDR6 on a 128 bit bus, delivering 176.0 GB/s. Memory clocks are identical at 1375 MHz with 11 Gbps effective, so the bandwidth gap comes entirely from bus width.

Clocks do not favor the larger chip. The A3000 Mobile runs at a 600 MHz base and 1230 MHz boost, while the A1000 Mobile runs at a 630 MHz base and 1140 MHz boost. The A1000 Mobile has a higher base clock by 30 MHz, but the A3000 Mobile has a higher boost clock by 90 MHz. The A3000 Mobile also carries a higher TDP at 70 W versus 60 W. Both use PCIe 4.0, but the A3000 Mobile uses x16 while the A1000 Mobile uses x8. The A3000 Mobile is a standard slot-width card, while the A1000 Mobile is listed as IGP. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Head-to-Head Benchmarks

The OpenCL test shows the largest margin. The A3000 Mobile scores 79091, while the A1000 Mobile scores 48703. That is a 62.4% advantage for the A3000 Mobile. In practical terms, this means the A3000 Mobile delivers well over one and a half times the OpenCL performance of the A1000 Mobile. This is the kind of result that separates a heavy compute part from a lighter mobile option. The A3000 Mobile also beats its own nearest rivals in this average context: the NVIDIA Quadro P6000 scores 69986, which is 0.2% below, and the AMD Radeon Pro WX 8200 scores 69870, which is 0.4% below. The A3000 Mobile even edges out the AMD Radeon RX 6600 LE, which scores 70829, a 1% deficit for the A3000 Mobile in that comparison. The NVIDIA CMP 90HX is further behind at 69000, a 1.7% gap.

The Vulkan test is closer but still decisive. The A3000 Mobile scores 61189, while the A1000 Mobile scores 46782. That is a 30.8% advantage for the A3000 Mobile. While the percentage is lower than OpenCL, it is still a clear win. The A1000 Mobile in this test sits near its own rivals: the AMD Radeon RX 6800 XT scores 48477, which is 1.5% above the A1000 Mobile, and the AMD Radeon RX 6550M scores 46702, which is 2.2% below. The Intel Arc A530M and AMD Radeon RX 5600M are also close, scoring 46614 and 46601 respectively, 2.4% and 2.5% below the A1000 Mobile. So the A1000 Mobile is competitive with its immediate peers, but the A3000 Mobile operates in a different class.

The recorded data shows two wins for the A3000 Mobile and zero for the A1000 Mobile. The average benchmark score gap is 22397 points. The A3000 Mobile also has a higher pixel rate at 78.72 GPixel/s versus 36.48 GPixel/s, and a higher texture rate at 157.4 GTexel/s versus 72.96 GTexel/s. FP32 compute is 10.08 TFLOPS versus 4.669 TFLOPS, and FP16 is identical to FP32 on both parts at a 1:1 ratio.

The Verdict

The data points to a clear hierarchy. The NVIDIA RTX A3000 Mobile is the stronger part by every measured metric. It wins both benchmark tests, has double the shading units, TMUs, ROPs, ray tracing cores, and tensor cores, and carries more memory with a wider bus and higher bandwidth. The 62.4% OpenCL lead and the 30.8% Vulkan lead are both substantial, and the average benchmark score of 70140 versus 47743 confirms the gap. The A3000 Mobile also ranks higher in the overall GPU distribution, at the 91st percentile versus the 85th.

For a user choosing between these two, the decision depends on whether the A3000 Mobile's advantages are needed. The A3000 Mobile draws 70 W versus 60 W, so it consumes more power, but it delivers nearly double the FP32 compute at 10.08 TFLOPS versus 4.669 TFLOPS. The A3000 Mobile also has a wider PCIe interface at x16 versus x8, which can matter for data transfer in compute scenarios. The A1000 Mobile, meanwhile, has a higher base clock and a smaller die, which may make it easier to integrate in constrained mobile chassis, but it does not win any recorded benchmark.

The release dates differ. The A3000 Mobile came out on 2021-04-11, and the A1000 Mobile came out on 2022-03-29. Both are now end-of-life, and both list Quadro Turing-M as their predecessor and Ada-MW as their successor. Neither has a launch MSRP in the database. The A3000 Mobile's nearest rivals include the NVIDIA Quadro P6000 and AMD Radeon Pro WX 8200, both within 0.4% of its average score. The A1000 Mobile's nearest rivals include the AMD Radeon RX 6800 XT, which is 1.5% faster, and the AMD Radeon RX 6550M, Intel Arc A530M, and AMD Radeon RX 5600M, which are all slightly slower. This means the A1000 Mobile sits in a tighter competitive band, while the A3000 Mobile is at the top of its own group.

The recommendation is straightforward: pick the A3000 Mobile for maximum compute and graphics performance, especially if OpenCL or Vulkan workloads are the priority. Pick the A1000 Mobile only if the lower TDP, smaller die, and higher base clock are the deciding factors in a specific mobile design, but be aware that it will trail in every recorded benchmark.
