Intel Arc A350M vs NVIDIA GeForce RTX 3070 Mobile Comparison

Head-to-Head Benchmarks

The recorded data contains two matching benchmark comparisons between the Intel Arc A350M and the NVIDIA GeForce RTX 3070 Mobile, and in both cases the NVIDIA part is decisively ahead. In Geekbench OpenCL, the Intel Arc A350M scores 24,546 against 92,939 for the RTX 3070 Mobile, a delta of -73.6%. In Geekbench Vulkan, the Intel part scores 24,747 against 86,768, a delta of -71.5%. These are not close contests. The NVIDIA GPU is roughly 3.7 times faster in OpenCL and 3.5 times faster in Vulkan based on the raw scores.

The average benchmark score for the Intel Arc A350M is 24,647, while the RTX 3070 Mobile averages 20,534. That comparison is misleading at first glance, because the NVIDIA part has a much larger benchmark suite recorded (ten entries versus two), including Passmark DX9, DX10, DX11, DX12, G2D, G3D, and GPU compute tests, plus 3DMark Steel Nomad DX12. The Intel part only has the two Geekbench entries. The RTX 3070 Mobile's average is dragged downward by low Passmark scores such as 64 in DirectX 12 and 113 in DirectX 10, while its Geekbench scores are far higher. When the two directly comparable workloads are isolated, the RTX 3070 Mobile wins both by wide margins.

Percentile placement reinforces the gap. The Intel Arc A350M sits at the 70th percentile against all GPUs in the database, while the RTX 3070 Mobile sits at the 65th percentile. Despite the lower percentile, the RTX 3070 Mobile's raw compute results in OpenCL and Vulkan dwarf those of the Intel part. The percentile difference likely reflects the broader mix of workloads recorded for the NVIDIA GPU, including legacy DirectX tests where it scores relatively low, versus the Intel GPU's narrow two-test record that only covers modern compute and graphics APIs.

Looking at nearest rivals for context, the Intel Arc A350M lands between the AMD Radeon RX 590 (24,744, delta -0.4%) and the NVIDIA RTX A5000 Mobile (24,763, delta -0.5%), with the AMD Radeon RX 6600 XT at 24,442 (delta 0.8%) and the NVIDIA GeForce GTX 1630 at 24,277 (delta 1.5%). The RTX 3070 Mobile, based on its average score, sits near the Intel Arc B570 (20,556, delta -0.1%) and the Intel Arc A750 (20,582, delta -0.2%), with the NVIDIA Quadro M4000M at 20,480 (delta 0.3%) and the AMD Radeon R9 M390X at 20,662 (delta -0.6%). The two GPUs are in completely different competitive neighborhoods when using the database's average score metric, although the head-to-head Geekbench results show an even larger separation than the averages suggest.

Architecture Differences

The two GPUs come from different manufacturers, process nodes, and architectural families. The Intel Arc A350M uses the DG2-128 chip with Xe-HPG architecture, built on TSMC's 6 nm process. It packs 7,200 million transistors on a 157 mm² die, giving a transistor density of 45.9 million per square millimeter. The NVIDIA GeForce RTX 3070 Mobile uses the GA104 chip with Ampere architecture, built on Samsung's 8 nm process. It contains 17,400 million transistors on a 392 mm² die, with a density of 44.4 million per square millimeter. The NVIDIA chip is larger in both transistor count and die size, while the Intel chip achieves a slightly higher transistor density despite being built on a smaller physical footprint.

Core counts differ substantially. The Intel Arc A350M has 768 shading units, 48 texture mapping units, 24 ROPs, and 6 ray tracing cores. The RTX 3070 Mobile has 5,120 shading units, 160 TMUs, 80 ROPs, 40 ray tracing cores, and 160 tensor cores. The NVIDIA GPU has roughly 6.7 times the shading units, 3.3 times the TMUs, 3.3 times the ROPs, and 6.7 times the ray tracing cores. The tensor core count of 160 on the NVIDIA side has no direct equivalent listed for the Intel part, which has a null tensor core field.

Clock speeds tell a different story. The Intel Arc A350M runs at a base clock of 1150 MHz and boosts to 2200 MHz. The RTX 3070 Mobile runs at 1110 MHz base and 1560 MHz boost. The Intel chip has a higher boost clock by 640 MHz, but the NVIDIA chip's massive core count advantage overwhelms that frequency advantage in raw throughput. Memory clocks are identical at 1750 MHz, yielding 14 Gbps effective on both parts.

The memory subsystem is another major divergence. The Intel Arc A350M has 4 GB of GDDR6 on a 64-bit bus, delivering 112.0 GB/s of bandwidth. The RTX 3070 Mobile has 8 GB of GDDR6 on a 256-bit bus, delivering 448.0 GB/s. That is exactly four times the bus width and four times the bandwidth, with double the capacity. The PCIe interface also differs: the Intel part uses PCIe 4.0 x8, while the NVIDIA part uses PCIe 4.0 x16.

Compute throughput numbers reflect the architectural gap. The Intel Arc A350M delivers 3.379 TFLOPS FP32 and 6.758 TFLOPS FP16 (2:1 ratio). The RTX 3070 Mobile delivers 15.97 TFLOPS FP32 and 15.97 TFLOPS FP16 (1:1 ratio). The NVIDIA GPU is roughly 4.7 times faster in FP32 and 2.4 times faster in FP16. Pixel rate is 52.80 GPixel/s for Intel versus 124.8 GPixel/s for NVIDIA. Texture rate is 105.6 GTexel/s versus 249.6 GTexel/s.

Power consumption differs as well. The Intel Arc A350M has a TDP of 25 W, while the RTX 3070 Mobile has a TDP of 115 W. The Intel part is listed as IGP slot width with no power connectors, while the NVIDIA part lists no power connectors either. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Intel part uses the Alchemist (Arc 3 Mobile) generation, released on 2022-03-29, while the NVIDIA part uses the GeForce 30 Mobile generation, released earlier on 2021-01-11. The NVIDIA part's predecessor is listed as GeForce 20 Mobile, while the Intel part has no predecessor. Both are end-of-life products.

The Verdict

The data shows a clear hierarchy. The NVIDIA GeForce RTX 3070 Mobile wins every directly comparable benchmark in the database, with deltas of -73.6% in OpenCL and -71.5% in Vulkan relative to the Intel Arc A350M. If the only question is which GPU delivers higher raw compute performance in these modern API workloads, the RTX 3070 Mobile is the answer without qualification.

The Intel Arc A350M is not without its own standing in the database. Its percentile rank of 70 is actually higher than the RTX 3070 Mobile's 65, and its average benchmark score of 24,647 exceeds the RTX 3070 Mobile's 20,534. However, these aggregate metrics are shaped by the different benchmark suites recorded for each GPU. The Intel part's two Geekbench results are both in the mid-24,000 range, while the RTX 3070 Mobile's ten results include several low Passmark scores that pull its average down. A buyer choosing a GPU strictly on the head-to-head data would select the RTX 3070 Mobile for OpenCL and Vulkan workloads.

The architecture comparison reinforces the verdict. The RTX 3070 Mobile has more shading units, more TMUs, more ROPs, more ray tracing cores, more memory capacity, four times the memory bandwidth, a wider PCIe interface, and roughly 4.7 times the FP32 throughput. The Intel part counters with a higher boost clock, a smaller die, lower power draw, and a more advanced process node. None of those advantages translate into benchmark wins in the recorded data.

For users constrained by power and physical footprint, the Intel Arc A350M's 25 W TDP and IGP form factor are meaningful qualifiers. The RTX 3070 Mobile draws 115 W and is a discrete mobile GPU. The database does not record a price for either part, so any decision must rest on performance, power, and feature data alone. Based on that data, the RTX 3070 Mobile is the stronger performer in every directly comparable test.
