Where Each One Wins

The RTX 5070 Ti Mobile wins in every benchmark category recorded. Its PassMark G3D score of 24004 and PassMark GPU compute score of 10101 show dominant performance in both rasterization and compute workloads. The Geekbench OpenCL score of 143870 and Vulkan score of 139213 further confirm its lead in general-purpose and graphics API workloads.

The Arc G3 has no recorded benchmark scores in the database, which means its wins are structural rather than measured. It wins on power efficiency by design: 25 W TDP versus 60 W, and it uses system shared memory, which can be advantageous in unified memory architectures where the CPU and GPU access the same pool. The Arc G3 also uses a 3 nm process versus 5 nm, which typically allows higher transistor density per watt, though the exact transistor count for the Intel part is unknown.

For workloads that favor raw throughput, texture fill, and pixel fill, the RTX 5070 Ti Mobile dominates. Its texture rate of 266.2 GTexel/s is 2.8 times the Arc G3’s 96.00 GTexel/s, and its pixel rate of 115.8 GPixel/s is 2.4 times the Arc G3’s 48.00 GPixel/s. Any application that stresses fill rates, ray tracing, or FP32 compute will favor the NVIDIA part.

The Arc G3’s advantage lies in its integration model. As an IGP with no power connectors and a 25 W TDP, it fits into thin, low-power portable devices. The RTX 5070 Ti Mobile, while also an IGP with no connectors, demands 60 W and a PCIe 5.0 x16 interface, which implies a more robust cooling solution and power delivery system.

Architecture Differences

The Intel Arc G3 uses the Xe3-LPG architecture on the Panther Lake chip, part of the Arc Graphics-M generation. This is Intel’s integrated graphics design, built on a 3 nm process at Intel’s own foundry. The architecture emphasizes efficiency and integration, with 10 ray tracing cores and support for DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The Xe3-LPG is a low-power variant of Intel’s Xe3 architecture, optimized for mobile integration rather than discrete performance.

The NVIDIA GeForce RTX 5070 Ti Mobile uses the Blackwell 2.0 architecture on the GB205 chip, part of the GeForce 50 Mobile generation. TSMC fabricates this chip on a 5 nm process, with 31,100 million transistors on a 263 mm² die. Blackwell 2.0 introduces 184 tensor cores alongside 46 ray tracing cores, enabling dedicated AI acceleration and hardware-accelerated ray tracing. The chip also supports the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

The memory architectures differ fundamentally. The Arc G3 uses system shared memory, meaning it has no dedicated VRAM and relies on the host’s memory subsystem. The RTX 5070 Ti Mobile uses 12 GB of GDDR7 on a 192-bit bus, delivering 672.0 GB/s of dedicated bandwidth. This difference affects not only capacity but also latency and bandwidth predictability: dedicated GDDR7 provides consistent high bandwidth, while shared memory performance varies with system configuration.

The tensor core count is another key divergence. The RTX 5070 Ti Mobile has 184 tensor cores, while the Arc G3 has none listed. This gives NVIDIA a significant advantage in AI workloads, including DLSS, neural rendering, and compute tasks that leverage tensor operations. The Arc G3’s FP16 throughput at 12.29 TFLOPS (2:1 ratio) suggests some form of packed math, but without tensor cores, its AI acceleration capabilities are limited.

Specification Differences

The RTX 5070 Ti Mobile has 5888 shading units, 184 texture mapping units, and 80 raster output units. The Arc G3 has 1280 shading units, 40 TMUs, and 20 ROPs. These are 4.6x, 4.6x, and 4.0x differences respectively, in NVIDIA’s favor.

Clock speeds differ substantially: the Arc G3 runs at 300 MHz base and 2400 MHz boost, while the RTX 5070 Ti Mobile runs at 847 MHz base and 1447 MHz boost. The Intel part’s higher boost clock partially compensates for its lower resource count, but not enough to close the performance gap.

Memory specifications are entirely different. The Arc G3 uses system shared memory with system dependent bandwidth, while the RTX 5070 Ti Mobile has 12 GB GDDR7, 192-bit bus, and 672.0 GB/s bandwidth. The NVIDIA memory clock is listed as 1750 MHz with 28 Gbps effective data rate.

Power and interface also differ. The Arc G3 has a 25 W TDP, while the RTX 5070 Ti Mobile has a 60 W TDP. Both use IGP slot width and no power connectors, but the RTX 5070 Ti Mobile uses PCIe 5.0 x16, while the Arc G3 uses an IGP bus interface. The release dates differ: the RTX 5070 Ti Mobile launched on 2025-02-28, while the Arc G3 launched on 2026-05-31, over a year later.

The RTX 5070 Ti Mobile’s predecessor is the GeForce 40 Mobile series, while the Arc G3 has no recorded predecessor or successor. The NVIDIA part has a transistor density of 118.3M per mm², while the Arc G3’s transistor count and die size are unknown.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark results between these two GPUs. However, the RTX 5070 Ti Mobile has extensive standalone benchmarks that establish its performance tier. Its PassMark G3D score of 24004 places it at the 80th percentile among all GPUs, with an average benchmark score of 35435. The Arc G3 has no recorded benchmarks and sits at the 50th percentile with an average score of 0, indicating no measured performance data exists.

The RTX 5070 Ti Mobile’s nearest rivals provide context. The NVIDIA Quadro GV100 scores 35520, just 0.2% higher. The AMD Radeon Pro Duo scores 35860, 1.2% higher. The NVIDIA A2 scores 34690, 2.1% lower. The NVIDIA T1000 scores 36289, 2.4% higher. This cluster shows the RTX 5070 Ti Mobile performs within a narrow band around 35,000 to 36,000 average benchmark points, trading places with professional and workstation-class GPUs.

In specific tests, the RTX 5070 Ti Mobile shows varied strengths. Its Geekbench OpenCL score of 143870 significantly exceeds its Vulkan score of 139213, suggesting OpenCL workloads benefit more from its architecture. The PassMark DirectX 9 score of 259 is the highest of its DirectX tests, while DirectX 12 scores only 102, indicating older API paths perform relatively better. The PassMark G2D score of 981 shows modest 2D performance, while G3D at 24004 dominates.

For the Arc G3, the absence of benchmark data means the analysis must rely on architectural specifications. Its FP32 throughput of 6.144 TFLOPS and texture rate of 96.00 GTexel/s indicate it would trail the RTX 5070 Ti Mobile by roughly 2.8x in raw compute and texture workloads. Its 48.00 GPixel/s pixel rate is 2.4x lower than the NVIDIA part’s 115.8 GPixel/s. In FP16, the Arc G3’s 12.29 TFLOPS (2:1) compares more favorably against the RTX 5070 Ti Mobile’s 17.04 TFLOPS (1:1), a 1.4x gap that narrows for mixed-precision workloads.

The Verdict

The data clearly shows the NVIDIA GeForce RTX 5070 Ti Mobile as the substantially more powerful GPU. Its 17.04 TFLOPS FP32, 672.0 GB/s memory bandwidth, and 5888 shading units place it in the 80th percentile of all GPUs, with benchmark scores clustering near professional workstation parts like the Quadro GV100 and Radeon Pro Duo. Any workload that demands raw compute, high fill rates, or dedicated AI acceleration through 184 tensor cores will favor this part.

The Intel Arc G3 targets a different use case entirely. Its 25 W TDP, system shared memory, and IGP bus interface indicate it is designed for ultra-portable, power-constrained devices where discrete performance is secondary to integration and efficiency. Its 3 nm process and 2400 MHz boost clock show Intel’s focus on power efficiency, and its 12.29 TFLOPS FP16 throughput suggests reasonable performance for mixed-precision tasks despite the lack of tensor cores.

For users who need maximum graphics performance in a mobile device, the RTX 5070 Ti Mobile is the only choice with measured data. Its benchmark scores, while not the very top of the database, place it comfortably ahead of the Arc G3’s unmeasured baseline. The Arc G3, without any recorded benchmarks, cannot be positioned as a performance competitor. Its strengths lie in its integration profile and low power draw, making it suitable for thin-and-light laptops where the RTX 5070 Ti Mobile’s 60 W TDP would require more substantial cooling.

The release timeline also matters: the RTX 5070 Ti Mobile launched in February 2025, while the Arc G3 arrived in May 2026. The later release allows the Arc G3 to leverage a more advanced 3 nm process, but the architectural resource gap remains decisive. The RTX 5070 Ti Mobile’s 31,100 million transistors and 263 mm² die provide a hardware advantage that the Arc G3’s unknown transistor count cannot match. Users seeking measured, verifiable performance should select the RTX 5070 Ti Mobile. Users prioritizing minimum power consumption and system-level memory sharing should consider the Arc G3, with the understanding that its performance remains unquantified in the database.
