NVIDIA GeForce RTX 5070 Ti Mobile vs NVIDIA RTX A1000 Mobile Comparison

Head-to-Head Benchmarks

The recorded head-to-head data contains two compute-oriented tests, and the NVIDIA GeForce RTX 5070 Ti Mobile wins both by a substantial margin. In Geekbench OpenCL, the RTX 5070 Ti Mobile scores 143870 against the RTX A1000 Mobile’s 48703, a delta of -66.1% from the perspective of the slower card. That means the RTX 5070 Ti Mobile is roughly 2.95 times faster in raw OpenCL compute. The gap is nearly identical in Geekbench Vulkan: the RTX 5070 Ti Mobile posts 139213, while the RTX A1000 Mobile manages 46782, a -66.4% delta. Again, the newer part delivers close to triple the performance in this API.

These are not marginal wins. The smallest delta across both tests is 66.1%, which places the RTX 5070 Ti Mobile in a completely different performance tier. The RTX A1000 Mobile has zero wins in the head-to-head set, while the RTX 5070 Ti Mobile takes both. However, the average benchmark score tells a slightly different story. The RTX A1000 Mobile has an average score of 47743, while the RTX 5070 Ti Mobile averages 35435. This discrepancy arises because the RTX 5070 Ti Mobile’s average includes several Passmark tests with very low scores (for example, Passmark DirectX 10 at 151, DirectX 11 at 237, DirectX 12 at 102, and DirectX 9 at 259), which drag its mean down despite the massive Geekbench wins. The RTX A1000 Mobile only has the two Geekbench scores in its record, so its average remains high.

When placed against the broader field, the RTX A1000 Mobile sits at the 85th percentile of all GPUs, while the RTX 5070 Ti Mobile is at the 80th percentile. Despite the RTX 5070 Ti Mobile’s dominance in the direct comparison, its percentile is lower due to the inclusion of those low Passmark scores in its record. The nearest rivals for the RTX A1000 Mobile are the AMD Radeon RX 6800 XT (avg score 48477, delta -1.5%), the AMD Radeon RX 6550M (46702, +2.2%), the Intel Arc A530M (46614, +2.4%), and the AMD Radeon RX 5600M (46601, +2.5%). The RTX A1000 Mobile is within 2.5% of all four, meaning it trades blows with those parts. For the RTX 5070 Ti Mobile, the nearest rivals are the NVIDIA Quadro GV100 (35520, -0.2%), AMD Radeon Pro Duo (35860, -1.2%), NVIDIA A2 (34690, +2.1%), and NVIDIA T1000 (36289, -2.4%). The RTX 5070 Ti Mobile sits within 2.4% of all four, indicating that its average score is competitive with a mixed set of workstation and datacenter cards, though none of them approach its Geekbench peaks.

Architecture Differences

The two GPUs come from different architectural generations and are fabricated on different nodes. The RTX A1000 Mobile uses the GA107 chip, built on the Ampere architecture, produced on Samsung’s 8 nm process. The RTX 5070 Ti Mobile uses the GB205 chip, based on Blackwell 2.0, fabricated by TSMC on a 5 nm node. The transistor counts reflect the generational jump: the RTX A1000 Mobile has 8,700 million transistors on a 200 mm² die, yielding a density of 43.5 million transistors per square millimeter. The RTX 5070 Ti Mobile packs 31,100 million transistors onto a 263 mm² die, reaching 118.3 million per square millimeter. That is a 2.7 times increase in density, which explains how the newer part fits far more compute units into a similar physical footprint.

The compute resources differ by a factor of roughly three. The RTX A1000 Mobile has 2048 shading units, 64 texture mapping units, and 32 raster operation units. The RTX 5070 Ti Mobile has 5888 shading units, 184 TMUs, and 80 ROPs. The ray tracing and tensor hardware scales accordingly: the RTX A1000 Mobile has 16 RT cores and 64 tensor cores, while the RTX 5070 Ti Mobile has 46 RT cores and 184 tensor cores. The raw throughput numbers follow this pattern. The RTX A1000 Mobile delivers 4.669 TFLOPS for both FP32 and FP16 (at 1:1 ratio), while the RTX 5070 Ti Mobile reaches 17.04 TFLOPS in both precisions, also at 1:1. Pixel and texture rates are similarly lopsided: 36.48 GPixel/s and 72.96 GTexel/s for the RTX A1000 Mobile, versus 115.8 GPixel/s and 266.2 GTexel/s for the RTX 5070 Ti Mobile.

Memory is another major divider. The RTX A1000 Mobile has 4 GB of GDDR6 on a 128-bit bus, with memory clocked at 1375 MHz (11 Gbps effective) and bandwidth of 176.0 GB/s. The RTX 5070 Ti Mobile has 12 GB of GDDR7 on a 192-bit bus, with memory at 1750 MHz (28 Gbps effective) and bandwidth of 672.0 GB/s. That is three times the capacity and 3.8 times the bandwidth. The bus interface also differs: the RTX A1000 Mobile uses PCIe 4.0 x8, while the RTX 5070 Ti Mobile uses PCIe 5.0 x16. Both are IGP (integrated graphics processor) form factors with no power connectors, and both list "Portable Device Dependent" for display outputs. The TDP for both is 60 W, which is notable: the RTX 5070 Ti Mobile achieves its massive performance lead within the same power envelope as the older part, a direct result of the node shrink and architectural efficiency.

The API support is identical on paper: both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The production status differs, with the RTX A1000 Mobile marked as end-of-life and the RTX 5070 Ti Mobile as active. The release dates are separated by nearly three years: the RTX A1000 Mobile launched in March 2022, while the RTX 5070 Ti Mobile launched in February 2025. The RTX A1000 Mobile’s predecessor is Quadro Turing-M and its successor is Ada-MW. The RTX 5070 Ti Mobile’s predecessor is GeForce 40 Mobile, and it has no successor listed.

The Verdict

The data points to a clear choice for any workload that relies on the two Geekbench compute tests. The RTX 5070 Ti Mobile is the superior part for OpenCL and Vulkan compute, delivering roughly three times the score in both. The 66% delta is consistent and decisive. If the task is heavy GPU compute, whether for rendering, simulation, or machine learning inference that can use these APIs, the RTX 5070 Ti Mobile is the only sensible pick from this pair.

The RTX A1000 Mobile does have one advantage in the recorded data: its average benchmark score is higher (47743 vs 35435). This is due to the RTX 5070 Ti Mobile’s inclusion of multiple Passmark tests with very low scores (all below 260 in the DirectX variants), which do not reflect its compute capability but nonetheless pull its average down. The RTX A1000 Mobile’s percentile rank (85th) also exceeds the RTX 5070 Ti Mobile’s (80th). However, these metrics are artifacts of the test set composition, not evidence of the RTX A1000 Mobile being faster. In the direct head-to-head tests, the RTX A1000 Mobile never wins.

For a buyer or system integrator choosing between these two for a mobile workstation, the decision hinges on whether the Passmark DirectX scores matter. If the workload involves legacy DirectX 9, 10, 11, or 12 applications, the RTX 5070 Ti Mobile’s Passmark scores (259, 151, 237, and 102, respectively) are low in absolute terms, but the RTX A1000 Mobile has no recorded Passmark scores at all, so no comparison can be made there. The only comparable data is the Geekbench pair, and the RTX 5070 Ti Mobile wins both. The RTX A1000 Mobile also has a smaller memory footprint (4 GB vs 12 GB), which could be a limiting factor for large datasets, but again, the RTX 5070 Ti Mobile’s memory is both larger and faster.

Where Each One Wins

The RTX 5070 Ti Mobile wins in every direct comparison available. In Geekbench OpenCL, it is 66.1% ahead. In Geekbench Vulkan, it is 66.4% ahead. It also wins on every architectural metric that matters for compute: shading units (5888 vs 2048), TMUs (184 vs 64), ROPs (80 vs 32), RT cores (46 vs 16), tensor cores (184 vs 64), FP32 throughput (17.04 vs 4.669 TFLOPS), texture rate (266.2 vs 72.96 GTexel/s), pixel rate (115.8 vs 36.48 GPixel/s), memory capacity (12 GB vs 4 GB), memory bandwidth (672.0 vs 176.0 GB/s), and bus width (192-bit vs 128-bit). It also has a newer PCIe interface (5.0 x16 vs 4.0 x8) and a smaller process node (5 nm vs 8 nm). For any workload that is limited by compute throughput, memory bandwidth, or ray tracing capability, the RTX 5070 Ti Mobile is the clear winner.

The RTX A1000 Mobile wins in exactly one recorded metric: the average benchmark score, where it leads 47743 to 35435. It also holds a higher percentile rank (85th vs 80th). These wins are statistical artifacts of the RTX 5070 Ti Mobile’s Passmark scores, which include several very low DirectX results (151, 237, 102, 259) that drag its average down. In real-world compute terms, the RTX A1000 Mobile is also more power-efficient per frame in the sense that it matches the RTX 5070 Ti Mobile’s 60 W TDP while delivering far less performance, but efficiency measured as performance per watt would favor the RTX 5070 Ti Mobile, given its roughly 3x score at the same power draw. The RTX A1000 Mobile also has a smaller die (200 mm² vs 263 mm²), which could matter for thermal density in very compact chassis, but no thermal data is recorded to confirm any benefit.

For use cases, the split is simple. The RTX A1000 Mobile is suitable for legacy or lightweight tasks where the Geekbench scores are sufficient and the 4 GB memory is not a bottleneck. It also sits within 2.5% of several midrange rivals (AMD Radeon RX 6550M, Intel Arc A530M, AMD Radeon RX 5600M), so it is competitive in that tier. The RTX 5070 Ti Mobile is the choice for high-end compute, large datasets (12 GB memory), and any application that can leverage its Vulkan or OpenCL performance. Its nearest rivals (Quadro GV100, Radeon Pro Duo, NVIDIA A2, NVIDIA T1000) are all within 2.4% in average score, but none of them appear in the head-to-head tests, so the direct comparison remains firmly in favor of the RTX 5070 Ti Mobile.
