NVIDIA GeForce RTX 3070 Mobile vs NVIDIA RTX A5000 Mobile Comparison

Where Each One Wins

The recorded data splits these two mobile Ampere GPUs into distinct roles. The NVIDIA RTX A5000 Mobile wins 7 of the 9 head-to-head benchmark comparisons, while the NVIDIA GeForce RTX 3070 Mobile takes only 2. That spread alone suggests the A5000 is the broader performer, but the specific tests it loses reveal where the GeForce part holds its ground.

The RTX A5000 Mobile dominates compute-oriented workloads. In Geekbench OpenCL, it posts 110877 against 92939, a 19.3% advantage. That is the largest single margin in the entire comparison. It also wins Passmark GPU Compute by 1.7% (6945 vs 6827), indicating the professional card sustains its lead even in non-graphics parallelism. For DirectX 12, the A5000 is ahead by 12.5% (72 vs 64), which matters for modern game engines and future-facing APIs. DirectX 9 and DirectX 10 also go to the A5000, with margins of 5.6% and 1.8% respectively.

The RTX 3070 Mobile, by contrast, wins the two tests that lean toward rasterization efficiency and 2D throughput. It beats the A5000 in Passmark DirectX 11 by 3.6% (138 vs 133) and in Passmark G2D by 1.9% (641 vs 629). These are narrower wins than the A5000's compute margin, but they indicate that for legacy DirectX 11 titles and desktop-style 2D operations, the GeForce part is the better choice.

In the aggregate, the A5000 sits at the 70th percentile of all GPUs in the database, while the RTX 3070 Mobile sits at the 65th. The average benchmark score for the A5000 is 24763, compared to 20534 for the 3070 Mobile. That 20.6% gap in average score aligns with the A5000's consistent win count, though the head-to-head deltas are smaller in several tests than the average would suggest.

Architecture Differences

Both GPUs share the same underlying silicon. They use the GA104 chip on an 8 nm Samsung process, with 17,400 million transistors on a 392 mm² die. The transistor density is identical at 44.4M per mm². Both are Ampere architecture parts, support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and connect via PCIe 4.0 x16. Memory type and bus width are also the same: GDDR6 on a 256-bit interface, with 448.0 GB/s of bandwidth and 1750 MHz memory clock (14 Gbps effective).

The differences begin with the execution resources. The RTX A5000 Mobile packs 6144 shading units, 192 TMUs, 96 ROPs, 48 RT cores, and 192 tensor cores. The RTX 3070 Mobile has 5120 shading units, 160 TMUs, 80 ROPs, 40 RT cores, and 160 tensor cores. That is a 20% deficit in every parallel compute block for the GeForce part, which explains why the A5000 leads in most compute-heavy tests.

Clock speeds tell a different story. The RTX 3070 Mobile has a higher base clock at 1110 MHz versus 900 MHz for the A5000. The boost clocks are nearly identical: 1560 MHz for the 3070, 1575 MHz for the A5000. The A5000's higher boost clock, combined with its larger shader count, yields 19.35 TFLOPS of FP32 and FP16 (1:1) performance. The 3070 Mobile delivers 15.97 TFLOPS for both. Pixel rate favors the A5000 at 151.2 GPixel/s versus 124.8 GPixel/s, and texture rate is 302.4 GTexel/s versus 249.6 GTexel/s.

Memory capacity is a major divider. The A5000 carries 16 GB of GDDR6, while the 3070 Mobile has 8 GB. With identical bus width and bandwidth, the extra capacity does not affect throughput, but it does allow larger datasets and more textures to reside on the GPU without spillover.

Power draw also differs. The A5000 has a TDP of 150 W, the 3070 Mobile is rated at 115 W. Neither card uses external power connectors, and both have display outputs described as portable device dependent. The A5000 was released on 2021-04-11, the 3070 Mobile on 2021-01-11. The A5000's predecessor is Quadro Turing-M and its successor is Ada-MW; the 3070 Mobile's predecessor is GeForce 20 Mobile.

Head-to-Head Benchmarks

The Geekbench OpenCL test delivers the clearest separation. The RTX A5000 Mobile scores 110877 against 92939 for the RTX 3070 Mobile, a delta of 19.3%. This is the largest win for either card in any test. It reflects the A5000's 20% advantage in shading units and tensor cores, and it is the kind of margin that matters for rendering, simulation, or any workload that scales with raw parallel throughput.

Geekbench Vulkan is much closer. The A5000 wins with 88144 versus 86768, a 1.6% margin. Vulkan's lower overhead may reduce the impact of the shader count difference, bringing the two GPUs nearly level. The same pattern appears in Passmark GPU Compute, where the A5000 scores 6945 against 6827, just 1.7% ahead.

DirectX 12 shows the second-largest gap. The A5000 scores 72, the 3070 Mobile scores 64, a 12.5% advantage for the professional card. DirectX 12 is the modern gaming API, and this margin suggests the A5000 is not just a compute specialist; it carries that lead into current-generation game engines.

The DirectX 9 result gives the A5000 a 5.6% win (169 vs 160), and DirectX 10 goes to the A5000 by 1.8% (115 vs 113). These are older APIs, but the A5000 still holds ahead, if narrowly.

The RTX 3070 Mobile's two wins are both close. In DirectX 11, it scores 138 against 133 for the A5000, a 3.6% margin. In G2D, it scores 641 against 629, a 1.9% margin. Neither win approaches the A5000's OpenCL lead, but they do show that the GeForce part has a slight edge in driver-optimized legacy rasterization and 2D acceleration.

Passmark G3D, which aggregates DirectX performance across versions, gives the A5000 a 3.1% win (15779 vs 15309). That is a modest but consistent lead, reinforcing the idea that the A5000 is the stronger overall GPU despite the 3070's wins in specific sub-tests.

The Verdict

The data points to a clear split. If the workload is compute-heavy, modern API-based, or requires large memory capacity, the RTX A5000 Mobile is the stronger choice. Its 19.3% OpenCL lead, 12.5% DirectX 12 lead, and 16 GB of VRAM make it the more capable professional workstation GPU. The 70th percentile ranking and average score of 24763 reinforce that position.

The RTX 3070 Mobile is not without merit. Its wins in DirectX 11 and G2D, while narrow, show that it handles legacy rasterization and 2D tasks with slightly better efficiency. Its 115 W TDP also makes it a lower-power option. For a user who prioritizes older DirectX 11 titles or needs a more power-efficient mobile GPU, the 3070 Mobile is the sensible pick.

But the overall record favors the A5000. Seven wins out of nine, with the largest margins going to the A5000, makes it the default recommendation for anyone who needs consistent performance across a wide range of benchmarks. The RTX 3070 Mobile is the specialist, not the generalist.
