Intel Arc G3 Extreme vs NVIDIA GeForce RTX 4080 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between these two mobile graphics solutions. The NVIDIA GeForce RTX 4080 Mobile holds the clear advantage across every benchmark category in the database, while the Intel Arc G3 Extreme has no recorded benchmark scores, resulting in zero wins for either side in direct head-to-head comparisons.

The RTX 4080 Mobile posts an average benchmark score of 38,135, placing it in the 81st percentile of all GPUs tracked by the database. Its nearest rivals confirm the competitive positioning: the NVIDIA GeForce MX570 sits at 38,299, a mere 0.4% higher, while the RTX 5080 Mobile reaches 38,349, just 0.6% above. The desktop RTX 4070 trails by 1.3% with a score of 37,648, and the Tesla P4 matches that 1.3% deficit at 37,628. These figures indicate the RTX 4080 Mobile sits in a tightly packed cluster of high-performance parts, with margins under 2% across all four nearest competitors.

In compute workloads, the Geekbench OpenCL score of 159,575 demonstrates substantial raw throughput capability. The Vulkan score of 145,807 trails slightly, showing a modest API-specific difference of roughly 8.6% within NVIDIA's own implementation. PassMark results paint a varied picture across DirectX versions: DirectX 9 delivers 286 points, DirectX 10 drops to 157, DirectX 11 rebounds to 244, and DirectX 12 falls to 96. The DirectX 12 result represents the lowest API score, suggesting optimization differences across legacy and modern graphics interfaces.

The PassMark G3D score of 24,926 and the GPU compute score of 11,191 further quantify the performance envelope. The 2D score of 929 indicates strong desktop rendering capabilities, though this matters less for gaming-oriented mobile workloads. The Intel Arc G3 Extreme, by contrast, has no benchmark entries in the database. Its percentile ranking sits at 50, and its average benchmark score is recorded as zero, reflecting the absence of measured performance data rather than an actual performance result.

Where Each One Wins

The RTX 4080 Mobile wins in every measurable category simply because it has recorded data. The Intel Arc G3 Extreme cannot claim any benchmark victories due to the lack of test results in the database. This asymmetry requires careful interpretation: the Arc G3 Extreme's zero wins reflect missing measurements, not necessarily inferior hardware.

For the RTX 4080 Mobile, the strongest relative performance appears in compute-heavy workloads. The Geekbench OpenCL score of 159,575 stands well above the Vulkan result of 145,807, indicating where the architecture excels. The PassMark GPU compute score of 11,191 combined with the G3D score of 24,926 suggests balanced performance between graphics rendering and general-purpose compute tasks.

The DirectX 9 score of 286 versus the DirectX 12 score of 96 shows a notable regression in newer API performance relative to older ones. This pattern indicates the RTX 4080 Mobile delivers its best efficiency in legacy DirectX 9 titles, while DirectX 12 workloads see reduced relative performance. The DirectX 11 score of 244 sits between these extremes, and DirectX 10 drops to 157, creating an uneven API performance profile.

The Intel Arc G3 Extreme's architecture includes 12 ray tracing cores and supports DirectX 12 Ultimate, but without benchmark data, no performance claims can be substantiated. The database records no wins for either GPU in direct head-to-head comparisons, so the practical outcome is that the RTX 4080 Mobile stands as the only part with verified performance metrics.

Architecture Differences

The two GPUs come from fundamentally different design philosophies. Intel builds the Arc G3 Extreme on the Panther Lake chip using the Xe3-LPG architecture, manufactured on a 3 nm process at Intel's foundry. NVIDIA's RTX 4080 Mobile uses the AD104 chip with Ada Lovelace architecture, produced on TSMC's 5 nm process. The transistor counts differ dramatically: Intel lists its transistor count as unknown, while NVIDIA reports 35,800 million transistors on a 294 mm² die, yielding a density of 121.8 million transistors per square millimeter.

The compute resources show stark contrasts. The Intel part contains 1,536 shading units, 48 texture mapping units, 24 ROPs, and 12 ray tracing cores. NVIDIA's RTX 4080 Mobile packs 7,424 shading units, 232 TMUs, 80 ROPs, and 58 ray tracing cores, along with 232 tensor cores. The Intel GPU has no tensor core listing, while the RTX 4080 Mobile's tensor cores support AI-accelerated workloads.

Clock speeds tell a complex story. The Arc G3 Extreme runs a 300 MHz base clock with a 2,500 MHz boost, while the RTX 4080 Mobile operates at 1,290 MHz base and 1,665 MHz boost. Despite the Intel part's higher boost clock, the NVIDIA GPU's massive shading unit advantage drives far higher throughput. The Arc G3 Extreme achieves 7.680 TFLOPS FP32 performance, while the RTX 4080 Mobile reaches 24.72 TFLOPS. The FP16 figures differ in approach: Intel delivers 15.36 TFLOPS with a 2:1 ratio, while NVIDIA matches its FP32 at 24.72 TFLOPS with a 1:1 ratio.

Memory configurations reflect their different market positions. The Arc G3 Extreme uses system-shared memory with a system-dependent bandwidth, making it an integrated GPU. The RTX 4080 Mobile has 12 GB of dedicated GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s bandwidth. The memory clock runs at 2,250 MHz with 18 Gbps effective speed for the NVIDIA part, while the Intel GPU's memory clock is listed as system shared.

The bus interface also differs: Intel uses an IGP connection, while NVIDIA employs PCIe 4.0 x16. Both parts are IGP slot width with no power connectors, though the TDP figures differ at 80 W for Intel and 110 W for NVIDIA. Display outputs are portable device dependent for both, and both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.
