Intel Arc A750 vs NVIDIA GeForce RTX 3070 Ti Mobile Comparison

Where Each One Wins

The benchmark record splits decisively along workload types. The NVIDIA GeForce RTX 3070 Ti Mobile wins 9 of the 10 recorded head-to-head tests, while the Intel Arc A750 takes exactly one. That lone victory, in the 3DMark Steel Nomad DX12 test, points to Intel’s strength in modern, hardware-accelerated ray tracing and mesh shading workloads. The NVIDIA part, however, dominates legacy DirectX paths, compute, and general 3D rendering.

For gamers running current DX12 titles with heavy ray tracing, the Intel Arc A750’s 3DMark Steel Nomad result (2612 vs. 2572) suggests it can hold its own or slightly edge ahead in that specific scenario. But for everything else, from older DX9/DX10/DX11 titles to OpenCL compute and Vulkan, the RTX 3070 Ti Mobile is the clear performer. The PassMark G3D gap is enormous: NVIDIA scores 17727 against Intel’s 12534, a 41.4% difference. That is not a marginal edge; it is a category-level separation.

Compute workloads also favor NVIDIA heavily. The PassMark GPU Compute test shows 7504 for the RTX 3070 Ti Mobile versus 5368 for the Arc A750, a 39.8% lead. The Geekbench OpenCL result reinforces this, with NVIDIA ahead by 7.6%. If the workload is GPGPU, scientific simulation, or machine learning inference, the NVIDIA architecture delivers substantially more throughput per available resource.

Legacy API performance is where Intel falls furthest behind. The PassMark DirectX 10 and DirectX 11 tests show NVIDIA winning by 90.8% and 112.5% respectively. These are massive deltas. Anyone running older game engines, emulators, or productivity apps that rely on pre-DX12 paths will see a dramatic difference in favor of the RTX 3070 Ti Mobile.

Architecture Differences

The two GPUs come from fundamentally different design philosophies and manufacturing processes. NVIDIA’s RTX 3070 Ti Mobile uses the GA104 chip built on an 8 nm Samsung process, with 17,400 million transistors on a 392 mm² die. Intel’s Arc A750 uses the DG2-512 chip on a 6 nm TSMC process, packing 21,700 million transistors into a 406 mm² die. The transistor density tells the story: Intel reaches 53.4M transistors per mm², while NVIDIA sits at 44.4M per mm². Intel’s newer process node gives it a density advantage, but that does not translate into benchmark superiority.

The compute configurations differ starkly. NVIDIA’s GA104 contains 5888 shading units, 184 TMUs, 96 ROPs, 46 RT cores, and 184 tensor cores. Intel’s DG2-512 has 3584 shading units, 224 TMUs, 112 ROPs, and 28 RT cores, with no tensor cores listed. NVIDIA runs more than 1.6 times the shader count of Intel, yet the FP32 throughput figures are close: 16.60 TFLOPS for NVIDIA versus 17.20 TFLOPS for Intel. Intel achieves higher raw FP32 with fewer shaders because of its higher clocks, base 2050 MHz and boost 2400 MHz, versus NVIDIA’s base 915 MHz and boost 1410 MHz.

Memory subsystems differ in bandwidth. Both use 8 GB of GDDR6 on a 256-bit bus, but Intel’s memory runs at 2000 MHz (16 Gbps effective) yielding 512.0 GB/s, while NVIDIA’s runs at 1750 MHz (14 Gbps effective) for 448.0 GB/s. Intel has a 14.3% bandwidth advantage, which likely contributes to its Steel Nomad win.

Power envelopes are not comparable. NVIDIA’s TDP is 115 W with no power connectors listed, designed for portable devices. Intel’s TDP is 225 W with a 1x 6-pin plus 1x 8-pin connector setup and a suggested PSU of 550 W. The Arc A750 is a dual-slot desktop card; the RTX 3070 Ti Mobile is a mobile part whose display outputs are listed as portable device dependent. These are different product classes, and the power draw reflects that.

Head-to-Head Benchmarks

The 3DMark Steel Nomad DX12 test is the single Intel win: 2612 for Arc A750 versus 2572 for RTX 3070 Ti Mobile, a 1.5% margin. That is close enough to be within run-to-run variance, but it is the only test where Intel comes out ahead in the recorded data.

The Geekbench Vulkan test shows NVIDIA’s strongest API-level advantage at 16.8%, scoring 100027 versus 85631. This indicates better driver optimization or architecture efficiency for Vulkan on NVIDIA. The OpenCL test follows the same pattern, with NVIDIA at 106022 versus 98554, a 7.6% lead.

PassMark results are lopsided. The DirectX 10 test: NVIDIA 124, Intel 65, a 90.8% delta. The DirectX 11 test: NVIDIA 153, Intel 72, a 112.5% delta. DirectX 12 narrows the gap: NVIDIA 73, Intel 70, only 4.3% apart. DirectX 9 shows NVIDIA ahead by 8.3% (196 vs. 181). The 2D test is closer: NVIDIA 783, Intel 732, a 7% edge.

The two largest deltas appear in general 3D and compute. PassMark G3D: NVIDIA 17727 versus Intel 12534, a 41.4% lead. PassMark GPU Compute: NVIDIA 7504 versus Intel 5368, a 39.8% lead. These are the tests where the shader count difference becomes decisive. NVIDIA’s 5888 shading units, even at lower clocks, produce far more aggregate throughput in these workloads than Intel’s 3584 shaders can manage.

Average benchmark scores confirm the overall hierarchy: NVIDIA’s average is 23518, Intel’s is 20582. NVIDIA sits at the 69th percentile of all GPUs, Intel at the 66th. In the nearest rivals list, NVIDIA’s closest competitor is the RTX 3080 Mobile at 23628, a 0.5% delta, while Intel’s nearest rival is the Arc B570 at 20556, a 0.1% delta. The RTX 3070 Ti Mobile competes in a higher performance tier, roughly 14% above the Arc A750’s average.

The Verdict

The data supports a clear split recommendation. For users prioritizing modern DX12 gaming with ray tracing, the Intel Arc A750’s Steel Nomad result is competitive, and its higher memory bandwidth (512.0 GB/s vs. 448.0 GB/s) plus faster pixel rate (268.8 GPixel/s vs. 135.4 GPixel/s) give it theoretical advantages in fill-rate-bound scenes. The Arc A750’s 34.41 TFLOPS FP16 (2:1 ratio) also indicates strong half-precision compute, useful for certain AI and media workloads.

For virtually every other use case, the NVIDIA GeForce RTX 3070 Ti Mobile is the superior part. Legacy API performance is not close: 90.8% and 112.5% leads in DX10 and DX11 make it the only sensible choice for older game libraries. Compute performance, both OpenCL and PassMark GPU Compute, favors NVIDIA by 7.6% to 39.8%. Vulkan performance favors NVIDIA by 16.8%. The average benchmark score is 14% higher, and the percentile ranking is 3 points higher.

The form factor difference cannot be ignored. The RTX 3070 Ti Mobile is a 115 W mobile GPU with no power connectors, built for laptops. The Arc A750 is a 225 W dual-slot desktop card requiring a 550 W PSU. Anyone choosing the Intel part must have desktop power delivery and cooling; anyone choosing the NVIDIA part gets laptop portability with a much lower power draw. The RTX 3070 Ti Mobile achieves its benchmark results at roughly half the TDP of the Arc A750, which is a significant efficiency statement in the recorded data.

Users who play mostly modern DX12 titles and value desktop expandability should consider the Arc A750. Users who need broad API compatibility, strong compute, or mobile form factors should pick the RTX 3070 Ti Mobile. The benchmark record favors NVIDIA in 9 of 10 tests, and the overall average score gap of 14% is decisive.
