Architecture Differences

The NVIDIA A2 is built on the Ampere architecture using the GA107 chip. It is fabricated on Samsung's 8 nm process, with a die size of 200 mm² and 8,700 million transistors. The RTX 5070 Mobile uses the Blackwell 2.0 architecture with the GB206 chip, manufactured by TSMC on a 5 nm process, with a die size of 181 mm² and 21,900 million transistors.

The process node difference is significant. The A2 has a transistor density of 43.5M per mm², while the RTX 5070 Mobile reaches 121.0M per mm². This explains how the RTX 5070 Mobile fits nearly 2.5 times the transistor count into a smaller die.

The A2 belongs to the Workstation Ampere generation, while the RTX 5070 Mobile is part of the GeForce 50 Mobile series. The A2 is a single-slot card with no display outputs, designed for server or accelerator duty. The RTX 5070 Mobile is an integrated graphics package (IGP) with display outputs that are portable device dependent.

RT core counts differ substantially. The A2 has 10 RT cores and 40 tensor cores. The RTX 5070 Mobile has 36 RT cores and 144 tensor cores. Shading units also differ, with the A2 offering 1,280 and the RTX 5070 Mobile offering 4,608.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The A2 uses a PCIe 4.0 x8 interface, while the RTX 5070 Mobile uses PCIe 5.0 x16.

The A2 is an end-of-life product, with its predecessor listed as Quadro Turing and its successor as Workstation Ada. The RTX 5070 Mobile is active, with its predecessor listed as GeForce 40 Mobile and no successor.

Where Each One Wins

The RTX 5070 Mobile wins in compute-heavy scenarios that favor raw shader throughput. Its FP32 performance is 13.13 TFLOPS versus 4.531 TFLOPS for the A2, a near threefold advantage. Texture rate also favors the RTX 5070 Mobile at 205.2 GTexel/s versus 70.80 GTexel/s. Pixel rate is closer, but still favors the mobile part at 68.40 GPixel/s versus 56.64 GPixel/s.

The RTX 5070 Mobile also wins on memory bandwidth. Its GDDR7 memory delivers 384.0 GB/s, nearly double the A2's 200.1 GB/s. This matters for workloads that stream large data sets, such as high-resolution textures or compute kernels with large working sets.

The A2 wins in memory capacity. Its 16 GB frame buffer doubles the 8 GB of the RTX 5070 Mobile. For inference workloads or rendering scenes that exceed 8 GB, the A2 has a clear advantage. The A2 also has a lower power envelope relative to its compute capability, with a 60 W TDP versus 50 W for the RTX 5070 Mobile. The A2 has no power connectors and requires a 250 W suggested PSU, while the RTX 5070 Mobile also has no power connectors but no PSU guidance is recorded.

The A2's profile is that of a compact, single-slot, no-output accelerator. It fits into servers or edge appliances where physical space and display capability are irrelevant. The RTX 5070 Mobile is a laptop GPU, designed to drive displays and deliver gaming or workstation performance in a portable chassis.

For gaming and DirectX workloads, the RTX 5070 Mobile is the stronger part. For capacity-bound memory applications, the A2 holds the edge. The RTX 5070 Mobile's Passmark G3D score of 20,355 indicates strong rasterization performance, while its G2D score of 896 is more modest.

Head-to-Head Benchmarks

The database records two direct head-to-head comparisons, both in Geekbench. The RTX 5070 Mobile dominates both.

In Geekbench OpenCL, the RTX 5070 Mobile scores 122,238 against the A2's 35,357. The delta is 71.1% in favor of the mobile GPU. This is a massive gap, and it aligns with the raw specification differences. The RTX 5070 Mobile has 4,608 shading units, 144 tensor cores, and 13.13 TFLOPS of FP32 throughput. The A2 has 1,280 shading units, 40 tensor cores, and 4.531 TFLOPS. OpenCL workloads scale strongly with shader count and memory bandwidth, and the RTX 5070 Mobile leads on both.

In Geekbench Vulkan, the RTX 5070 Mobile scores 116,960 against the A2's 34,023. The delta is 70.9%. Vulkan performance tracks the same architectural strengths. The RTX 5070 Mobile's higher texture rate, 205.2 GTexel/s versus 70.80 GTexel/s, and its higher pixel rate, 68.40 GPixel/s versus 56.64 GPixel/s, contribute to this result.

The A2's nearest rivals in the database are the NVIDIA T1000 8 GB with an average score of 34,561 and a delta of 0.4%, the AMD Radeon HD 7970 with 34,541 and a delta of 0.4%, the NVIDIA TITAN V with 34,355 and a delta of 1%, and the NVIDIA RTX A1000 with 34,207 and a delta of 1.4%. The A2 sits at the top of this cluster, but only by a hair. Its percentile versus all GPUs is 79.

The RTX 5070 Mobile's nearest rivals are the NVIDIA GeForce RTX 3070 Ti with an average score of 29,945 and a delta of -0.1%, the NVIDIA GeForce RTX 2080 Ti with 29,783 and a delta of 0.5%, the AMD Radeon RX 6800 with 30,095 and a delta of -0.6%, and the AMD Radeon RX 6700 with 30,433 and a delta of -1.7%. The RTX 5070 Mobile sits slightly below the RTX 3070 Ti and RX 6800 in average score, but above the RTX 2080 Ti. Its percentile versus all GPUs is 75.

The average benchmark score discrepancy is worth noting. The A2 averages 34,690, while the RTX 5070 Mobile averages 29,928. This is because the RTX 5070 Mobile's Passmark results are inconsistent. Its Passmark G3D score is a strong 20,355, and its GPU compute score is 8,279. But its DirectX sub-tests are very low: 129 for DirectX 10, 192 for DirectX 11, 93 for DirectX 12, and 214 for DirectX 9. Its G2D score is 896. These low sub-scores drag down the average.

The A2 has no Passmark records in the database, only the two Geekbench scores. Its average is therefore based on a smaller sample, and both samples are strong relative to its rivals.

The recorded data shows a clear split. If the workload is OpenCL or Vulkan compute, the RTX 5070 Mobile is decisively faster. If the workload is capacity-bound, the A2's 16 GB frame buffer is the deciding factor. The RTX 5070 Mobile's 8 GB is half that, and while its bandwidth is nearly double, some workloads simply need the capacity. The A2 also has the advantage of a higher boost clock at 1770 MHz versus 1425 MHz, though the RTX 5070 Mobile compensates with far more execution units.
