NVIDIA A2 vs NVIDIA GeForce RTX 5070 Ti Mobile Comparison

The benchmark data shows a decisive generational gap: the NVIDIA GeForce RTX 5070 Ti Mobile outperforms the NVIDIA A2 by an average of 2.1% in aggregate score, but in raw compute tests, the margin expands to over 300%. The RTX 5070 Ti Mobile is a Blackwell 2.0 architecture part built for mobile gaming, while the A2 is an Ampere-based workstation accelerator that is now end-of-life. These two GPUs are not direct competitors; the data positions them in entirely different performance classes.

Head-to-Head Benchmarks

The only two shared benchmark results are Geekbench OpenCL and Geekbench Vulkan, and the RTX 5070 Ti Mobile dominates both. In Geekbench OpenCL, the RTX 5070 Ti Mobile scores 143,870 against the A2’s 35,357, a delta of 306.9%. The Vulkan result is even more lopsided: 139,213 for the RTX 5070 Ti Mobile versus 34,023 for the A2, representing a 309.2% advantage. These are not marginal wins; they indicate that the RTX 5070 Ti Mobile delivers roughly four times the raw compute throughput in these API workloads.

The A2 does not win a single head-to-head benchmark. Its only two recorded scores — 35,357 in OpenCL and 34,023 in Vulkan — are both less than a quarter of the RTX 5070 Ti Mobile’s results. The average benchmark score tells a similar story: the RTX 5070 Ti Mobile averages 35,435 across all tests, while the A2 averages 34,690. The RTX 5070 Ti Mobile’s nearest rival, the NVIDIA Quadro GV100, scores 35,520 (only 0.2% higher), placing the RTX 5070 Ti Mobile in the 80th percentile of all GPUs. The A2 sits at the 79th percentile, with its closest competitor being the NVIDIA T1000 8 GB at 34,561 (0.4% lower).

It is important to note that the RTX 5070 Ti Mobile has a much broader benchmark profile, including Passmark tests that the A2 lacks entirely. In Passmark G3D, the RTX 5070 Ti Mobile scores 24,004; in Passmark GPU Compute, it scores 10,101; and in DirectX 11, it scores 237. These additional results contribute to its higher average score, but even in the shared tests, the performance gap is overwhelming.

Architecture Differences

The architectural divide is stark. The RTX 5070 Ti Mobile uses the GB205 chip built on NVIDIA’s Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The A2 uses the GA107 chip on the older Ampere architecture, fabricated on an 8 nm process at Samsung. This process difference is fundamental: the RTX 5070 Ti Mobile packs 31,100 million transistors into a 263 mm² die, yielding a density of 118.3 million transistors per mm². The A2 contains only 8,700 million transistors on a 200 mm² die, for a density of 43.5 million per mm². The RTX 5070 Ti Mobile has over 3.5 times the transistor count in only 1.3 times the die area.

The compute resources are similarly mismatched. The RTX 5070 Ti Mobile has 5,888 shading units, 184 texture mapping units, 80 ROPs, 46 ray tracing cores, and 184 tensor cores. The A2 has 1,280 shading units, 40 TMUs, 32 ROPs, 10 ray tracing cores, and 40 tensor cores. The RTX 5070 Ti Mobile has 4.6 times the shading units, 4.6 times the TMUs, 2.5 times the ROPs, 4.6 times the ray tracing cores, and 4.6 times the tensor cores. This is not a refinement; it is a full generational leap.

Memory architecture also differs. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The A2 uses 16 GB of GDDR6 on a 128-bit bus, delivering 200.1 GB/s. The RTX 5070 Ti Mobile has more than three times the memory bandwidth despite having less capacity. The pixel and texture rates follow suit: the RTX 5070 Ti Mobile produces 115.8 GPixel/s and 266.2 GTexel/s, versus the A2’s 56.64 GPixel/s and 70.80 GTexel/s.

Specification Differences

The two GPUs differ across nearly every specification field. The process node differs: 5 nm for the RTX 5070 Ti Mobile versus 8 nm for the A2. The foundry differs: TSMC versus Samsung. Clock speeds are inverted in a notable way — the A2 has a higher base clock of 1440 MHz and boost clock of 1770 MHz, while the RTX 5070 Ti Mobile runs at 847 MHz base and 1447 MHz boost. Despite lower clocks, the RTX 5070 Ti Mobile achieves far higher throughput due to its massive core count and newer architecture.

Memory specifications differ in size, type, bus width, and bandwidth: 12 GB GDDR7 on a 192-bit bus at 672.0 GB/s for the RTX 5070 Ti Mobile, versus 16 GB GDDR6 on a 128-bit bus at 200.1 GB/s for the A2. The RTX 5070 Ti Mobile has a memory clock of 1750 MHz (28 Gbps effective), while the A2 runs at 1563 MHz (12.5 Gbps effective).

The compute output is dramatically different: the RTX 5070 Ti Mobile delivers 17.04 TFLOPS FP32 and FP16 (1:1), while the A2 delivers 4.531 TFLOPS FP32 and FP16 (1:1). The RTX 5070 Ti Mobile has nearly four times the floating-point throughput. Both have a 60 W TDP, but the A2 lists a suggested PSU of 250 W, while the RTX 5070 Ti Mobile does not specify one. The RTX 5070 Ti Mobile uses a PCIe 5.0 x16 interface and is an integrated (IGP) form factor, while the A2 uses PCIe 4.0 x8 and is a single-slot card with no display outputs. The A2 also has no display outputs, while the RTX 5070 Ti Mobile’s outputs are listed as "Portable Device Dependent."

The A2 is end-of-life, released on 2021-11-09, with its predecessor being Quadro Turing and successor being Workstation Ada. The RTX 5070 Ti Mobile is active, released 2025-02-28, with its predecessor being GeForce 40 Mobile.

Where Each One Wins

The RTX 5070 Ti Mobile wins every measurable benchmark category. In Geekbench OpenCL, it is 306.9% ahead. In Geekbench Vulkan, it is 309.2% ahead. It also has a full suite of Passmark results — DirectX 10 (151), DirectX 11 (237), DirectX 12 (102), DirectX 9 (259), G2D (981), G3D (24,004), and GPU Compute (10,101) — none of which the A2 has recorded scores for. The RTX 5070 Ti Mobile is the clear choice for any workload requiring high compute throughput, modern API support, or ray tracing performance, given its 46 RT cores versus the A2’s 10.

The A2’s only advantages are structural, not performance-based. It has 16 GB of memory versus 12 GB, which could be beneficial for very large datasets that fit within its 200.1 GB/s bandwidth. It also has a lower transistor count and smaller die, which may imply lower manufacturing complexity, but the TDP is identical at 60 W. The A2 is single-slot and uses PCIe 4.0 x8, which could be easier to integrate into existing servers, but it lacks any display outputs. For gaming, the RTX 5070 Ti Mobile is the only option with portable-device-dependent outputs.

The Verdict

The data is unambiguous: the NVIDIA GeForce RTX 5070 Ti Mobile is the superior GPU by every performance metric measured. It is 2.1% ahead in average benchmark score, 306.9% ahead in OpenCL, and 309.2% ahead in Vulkan. Its architecture is two generations newer (Blackwell 2.0 versus Ampere), it has 4.6 times the shading units, and it delivers 17.04 TFLOPS versus 4.531 TFLOPS. The RTX 5070 Ti Mobile is in the 80th percentile of all GPUs, while the A2 is in the 79th.

The A2’s case rests entirely on its 16 GB memory capacity and its status as a low-power (60 W) single-slot accelerator with no display outputs. It is end-of-life, with a successor already named (Workstation Ada). If a workload requires more than 12 GB of VRAM, the A2 has an edge in capacity, but its bandwidth is only 200.1 GB/s, which severely limits its usefulness for memory-intensive tasks. The RTX 5070 Ti Mobile is the better choice for anyone who needs raw compute, modern API support, or ray tracing. The A2 is a legacy product that the data shows is outclassed in every shared test. For new deployments, the RTX 5070 Ti Mobile is the only rational pick based on benchmark evidence.
