NVIDIA GeForce RTX 5070 Ti Mobile vs NVIDIA RTX A400 Comparison

Head-to-Head Benchmarks

The benchmark data presents a decisive sweep. The NVIDIA GeForce RTX 5070 Ti Mobile wins all nine recorded head-to-head comparisons against the NVIDIA RTX A400, with the margin varying dramatically by workload category. The largest gap appears in synthetic compute tests: in Geekbench OpenCL, the RTX 5070 Ti Mobile scores 143,870 versus the RTX A400's 22,844, a 529.8% advantage. The Vulkan result follows the same pattern, with 139,213 against 22,237, a 526% lead.

The DirectX legacy tests show similarly lopsided results. In Passmark DirectX 11, the RTX 5070 Ti Mobile records 237 versus 37, a 540.5% delta, which is the single largest percentage gap across all tests. DirectX 10 shows a 371.9% advantage (151 versus 32), while DirectX 12 narrows somewhat to 277.8% (102 versus 27). The DirectX 9 test, often a measure of older API efficiency, still favors the RTX 5070 Ti Mobile by 197.7%, with scores of 259 and 87.

The 3D rendering and compute workloads reinforce this hierarchy. In Passmark G3D, the RTX 5070 Ti Mobile scores 24,004 against 5,983, a 301.2% margin. The GPU compute test shows 10,101 versus 2,557, a 295% difference. Even the 2D graphics test, which typically shows the smallest performance gap between any two GPUs, favors the RTX 5070 Ti Mobile: 981 versus 899, a modest 9.1% advantage. This near-sweep in 2D, where the A400's single-slot workstation design might be expected to compete, indicates the RTX 5070 Ti Mobile holds a fundamental execution advantage even in lightly threaded desktop composition tasks.

The average benchmark score tells a similar story. The RTX 5070 Ti Mobile averages 35,435 across all recorded tests, placing it in the 80th percentile of all GPUs in the database. The RTX A400 averages 6,078, sitting in the 35th percentile. The nearest rivals for the RTX 5070 Ti Mobile include the NVIDIA Quadro GV100 (average 35,520, a 0.2% difference), the AMD Radeon Pro Duo (35,860, 1.2% higher), and the NVIDIA A2 (34,690, 2.1% lower). For the RTX A400, its closest competitor is the NVIDIA GeForce MX230 at 6,077 (0% delta), followed by the Quadro P2000 at 6,049 (0.5% higher). The data indicates these two GPUs occupy entirely different performance tiers, with the RTX 5070 Ti Mobile delivering roughly five to six times the aggregate throughput.

Architecture Differences

The two GPUs represent distinct architectural generations and design philosophies. The RTX 5070 Ti Mobile uses the GB205 chip built on Blackwell 2.0 architecture, fabricated on a 5 nm process at TSMC. The RTX A400 uses the GA107 chip on Ampere architecture, fabricated on an 8 nm process at Samsung. This node difference directly contributes to the transistor density disparity: the GB205 packs 31,100 million transistors into a 263 mm² die, yielding 118.3 million transistors per mm². The GA107 contains 8,700 million transistors on a 200 mm² die, for a density of 43.5 million per mm².

The compute resource allocation differs even more sharply than the process node. The RTX 5070 Ti Mobile carries 5,888 shading units, 184 texture mapping units, and 80 ROPs. The RTX A400 has 768 shading units, 24 TMUs, and 16 ROPs. This corresponds to a 7.7x difference in shading unit count and a 7.7x difference in TMUs, while the ROP gap is 5x. The RTX 5070 Ti Mobile also includes 46 RT cores and 184 tensor cores, versus 6 RT cores and 24 tensor cores on the RTX A400. The RT core count difference is 7.7x, and the tensor core difference is 7.7x, matching the shading unit ratio.

The memory subsystem reinforces the performance separation. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 memory on a 192-bit bus, delivering 672.0 GB/s of bandwidth. The RTX A400 uses 4 GB of GDDR6 on a 64-bit bus, delivering 96.00 GB/s. The bandwidth difference is exactly 7x, and the memory capacity difference is 3x. Clock speeds tell a different story: the RTX A400 runs at a 1417 MHz base and 1762 MHz boost, while the RTX 5070 Ti Mobile runs at 847 MHz base and 1447 MHz boost. The A400 has higher absolute clocks, but the massive core count advantage of the GB205 overwhelms this in practice.

The pixel and texture rates demonstrate the aggregate throughput. The RTX 5070 Ti Mobile achieves 115.8 GPixel/s and 266.2 GTexel/s, compared to 28.19 GPixel/s and 42.29 GTexel/s for the RTX A400. The FP32 compute figures are 17.04 TFLOPS versus 2.706 TFLOPS, a 6.3x difference. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature parity is not a differentiator. The RTX 5070 Ti Mobile uses a PCIe 5.0 x16 interface, while the RTX A400 uses PCIe 4.0 x8, which affects host transfer bandwidth for data-intensive workloads.

The Verdict

The benchmark data indicates a clear hierarchy between these two GPUs. The NVIDIA GeForce RTX 5070 Ti Mobile wins every single head-to-head comparison, with deltas ranging from 9.1% in 2D graphics to 540.5% in DirectX 11. The average benchmark score of 35,435 versus 6,078 places the RTX 5070 Ti Mobile in the 80th percentile of all GPUs, while the RTX A400 sits in the 35th percentile. The nearest rivals for the RTX 5070 Ti Mobile, such as the Quadro GV100 (35,520 average, 0.2% higher) and the Radeon Pro Duo (35,860, 1.2% higher), demonstrate that it competes at a professional high-end tier. The RTX A400's nearest rivals, including the GeForce MX230 (6,077, 0% delta) and the Quadro P2000 (6,049, 0.5% higher), show that it occupies an entry-level position.

The data suggests the RTX 5070 Ti Mobile is the superior choice for any workload that stresses compute, memory bandwidth, or 3D rendering. Its 17.04 TFLOPS FP32 performance against 2.706 TFLOPS, combined with 672.0 GB/s memory bandwidth against 96.00 GB/s, provides a mathematical foundation for its benchmark dominance. The RTX A400 offers a lower TDP (50 W versus 60 W), a smaller physical footprint (163 mm length versus portable-device-dependent), and a fixed set of 4x mini-DisplayPort outputs, which may be relevant for specific workstation configurations.

For users who need raw throughput, the RTX 5070 Ti Mobile is the clear winner from the recorded data. For users who require a compact, single-slot card with multiple display outputs and lower power draw, the RTX A400 has a narrower but real advantage in physical integration. The performance gap is so large that any GPU-bound workload will favor the RTX 5070 Ti Mobile overwhelmingly.

Where Each One Wins

The RTX 5070 Ti Mobile wins in every benchmark category recorded, but the degree of its advantage varies. The largest margins occur in DirectX 11 (540.5%), OpenCL (529.8%), and Vulkan (526%), indicating that compute-heavy and modern API workloads benefit most from the GB205's massive core count and bandwidth. The smallest margin is in 2D graphics (9.1%), where the RTX A400's higher clock speeds partially compensate for its lower core count.

The RTX A400's only areas of relative strength are its lower TDP (50 W versus 60 W), its fixed 4x mini-DisplayPort 1.4a outputs, and its single-slot form factor. For a workstation that requires multiple monitors and minimal internal space, the A400 provides a defined physical configuration. The RTX 5070 Ti Mobile's display outputs are portable device dependent, meaning its connectivity varies by laptop design.

For compute tasks such as GPU rendering, machine learning inference, or scientific calculations, the RTX 5070 Ti Mobile's 184 tensor cores and 46 RT cores, combined with 17.04 TFLOPS FP32, dominate. For light desktop workloads or applications that only need basic 3D acceleration, the RTX A400's 2.706 TFLOPS and 96.00 GB/s bandwidth are sufficient, but the data shows the RTX 5070 Ti Mobile still outperforms it even in the 2D test.

The release dates also indicate generational positioning: the RTX 5070 Ti Mobile launched on 2025-02-28, while the RTX A400 launched on 2024-04-15. The RTX 5070 Ti Mobile's predecessor is the GeForce 40 Mobile series, while the RTX A400's predecessor is Quadro Turing and its successor is Workstation Ada. This places the RTX A400 in a transitional workstation lineup, while the RTX 5070 Ti Mobile represents the current mobile flagship tier. The RTX 5070 Ti Mobile's nearest rivals in the database, including the Quadro GV100 and Radeon Pro Duo, are all high-end professional GPUs, whereas the RTX A400's nearest rivals are entry-level mobile and integrated solutions. The performance positioning could not be more distinct.
