Architecture Differences

Both GPUs are built on NVIDIA's Ampere architecture using the GA104 chip, manufactured on Samsung's 8 nm process. The transistor count is identical at 17,400 million, and the die size is the same at 392 mm², resulting in a transistor density of 44.4M / mm² for both. The foundry is Samsung, and both use a PCIe 4.0 x16 bus interface.

The core configurations differ, with the RTX A5000 Mobile packing 6144 shading units, 192 texture mapping units, and 96 ROPs. The RTX 3070 Ti Mobile has 5888 shading units, 184 TMUs, and the same 96 ROPs. This gives the A5000 Mobile a higher pixel rate of 151.2 GPixel/s and texture rate of 302.4 GTexel/s, compared to 135.4 GPixel/s and 259.4 GTexel/s for the RTX 3070 Ti Mobile.

Ray tracing and tensor core counts follow the same pattern: the A5000 Mobile has 48 RT cores and 192 tensor cores, while the RTX 3070 Ti Mobile has 46 RT cores and 184 tensor cores. The FP32 and FP16 performance is also higher on the A5000 Mobile at 19.35 TFLOPS (1:1 ratio), versus 16.60 TFLOPS on the RTX 3070 Ti Mobile.

The memory subsystems share the same 256-bit bus and 448.0 GB/s bandwidth, but the A5000 Mobile doubles the capacity to 16 GB of GDDR6, while the RTX 3070 Ti Mobile offers 8 GB. The memory clock is identical at 1750 MHz (14 Gbps effective). Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, and both are marked as end-of-life products with display outputs described as "Portable Device Dependent."

Head-to-Head Benchmarks

The head-to-head data shows a clear split: the RTX A5000 Mobile wins one test, while the RTX 3070 Ti Mobile wins eight. The single victory for the A5000 Mobile comes in Geekbench OpenCL, where it scores 110877 against 106022, a 4.6% margin. This suggests the A5000 Mobile has a slight edge in general-purpose compute workloads that favor its higher shading unit count and clock speed.

In Geekbench Vulkan, the RTX 3070 Ti Mobile turns the tables, scoring 100027 versus 88144, an 11.9% advantage. This is the largest delta in the compute-oriented tests and indicates the RTX 3070 Ti Mobile has better optimization for Vulkan's graphics and compute pipeline, despite having fewer cores.

The Passmark suite shows consistent wins for the RTX 3070 Ti Mobile across all DirectX versions. In DirectX 10, it scores 124 versus 115, a 7.3% lead. DirectX 11 shows a larger gap: 153 against 133, a 13.1% advantage. DirectX 12 is nearly a tie at 73 versus 72, a 1.4% margin. DirectX 9 delivers the second-largest gap, with the RTX 3070 Ti Mobile scoring 196 versus 169, a 13.8% lead.

The 2D and 3D performance categories reinforce the RTX 3070 Ti Mobile's dominance. Passmark G2D shows a 19.7% advantage (783 vs 629), the largest single delta in the entire comparison. Passmark G3D, which is often a strong indicator of overall gaming performance, gives the RTX 3070 Ti Mobile an 11% lead with a score of 17727 versus 15779.

Finally, in Passmark GPU Compute, the RTX 3070 Ti Mobile scores 7504 against 6945, a 7.4% margin. This is notable because it contradicts the OpenCL result, where the A5000 Mobile was ahead. The divergence suggests the two GPUs respond differently to various compute APIs and workloads, with the A5000 Mobile favoring OpenCL specifically while the RTX 3070 Ti Mobile performs better in Passmark's proprietary compute test.

Specification Differences

The primary specification differences are concentrated in core counts, memory capacity, clock speeds, and power consumption. The RTX A5000 Mobile has 6144 shading units, 192 TMUs, 48 RT cores, and 192 tensor cores, while the RTX 3070 Ti Mobile has 5888 shading units, 184 TMUs, 46 RT cores, and 184 tensor cores. The ROP count is identical at 96.

Memory capacity is a major differentiator: 16 GB on the A5000 Mobile versus 8 GB on the RTX 3070 Ti Mobile, though both use GDDR6 with a 256-bit bus and 448.0 GB/s bandwidth. The memory clock is the same at 1750 MHz (14 Gbps effective).

Clock speeds differ in both directions. The A5000 Mobile has a lower base clock of 900 MHz versus 915 MHz, but a higher boost clock of 1575 MHz versus 1410 MHz. This results in higher theoretical throughput for the A5000 Mobile: 19.35 TFLOPS FP32 and FP16, 151.2 GPixel/s, and 302.4 GTexel/s, compared to 16.60 TFLOPS, 135.4 GPixel/s, and 259.4 GTexel/s for the RTX 3070 Ti Mobile.

Thermal design power is another clear distinction. The RTX A5000 Mobile is rated at 150 W, while the RTX 3070 Ti Mobile draws 115 W. Both use no power connectors (likely relying on the motherboard) and have no slot width or dimensions listed. The release dates differ, with the A5000 Mobile launching on 2021-04-11 and the RTX 3070 Ti Mobile on 2022-01-03. The A5000 Mobile's predecessor is Quadro Turing-M and its successor is Ada-MW, while the RTX 3070 Ti Mobile's predecessor is GeForce 20 Mobile with no listed successor.

The Verdict

The data paints a clear picture for most use cases. The NVIDIA GeForce RTX 3070 Ti Mobile wins eight of nine head-to-head benchmarks, including all Passmark DirectX tests and the G3D test, which is the most representative of general graphics performance. Its 11% lead in Passmark G3D (17727 vs 15779) and 13.1% lead in DirectX 11 (153 vs 133) make it the stronger choice for gaming and DirectX-based applications. The 19.7% advantage in G2D also suggests better 2D and UI acceleration.

However, the RTX A5000 Mobile is not without merit. Its 16 GB memory capacity is double the RTX 3070 Ti Mobile's 8 GB, which could matter for large datasets or high-resolution textures in professional workloads. Its 4.6% win in Geekbench OpenCL (110877 vs 106022) indicates a specific strength in OpenCL compute, and its higher boost clock and core counts give it higher theoretical peak throughput (19.35 TFLOPS vs 16.60 TFLOPS).

The RTX A5000 Mobile also carries a higher TDP of 150 W versus 115 W, which means it may require more robust cooling in a laptop chassis. Its average benchmark score of 24763 is higher than the RTX 3070 Ti Mobile's 23518, placing it in the 70th percentile versus the 69th. But this aggregate advantage is driven by the OpenCL score and does not translate into wins in the Passmark suite.

The verdict is straightforward: choose the RTX 3070 Ti Mobile for DirectX gaming and general graphics workloads where its benchmark wins are consistent and often large. Choose the RTX A5000 Mobile for OpenCL-heavy compute tasks or when 16 GB of memory is a hard requirement, accepting its lower performance in most other tests. For users prioritizing raw benchmark dominance, the RTX 3070 Ti Mobile is the data-backed winner.
