Architecture Differences

The Intel Arc G3 and NVIDIA GeForce RTX 4080 SUPER are fundamentally different classes of graphics hardware. The Arc G3 is an integrated GPU, meaning it is part of the Panther Lake processor package and shares system memory for all graphics operations. It is built on Intel's Xe3-LPG architecture, which is designed for low-power mobile and portable devices. The RTX 4080 SUPER, in contrast, is a discrete add-in board based on the AD103 chip using NVIDIA's Ada Lovelace architecture, manufactured by TSMC on a 5 nm process.

The compute resources differ substantially. The Arc G3 has 1280 shading units, 40 texture mapping units, 20 render output units, and 10 ray tracing cores. The RTX 4080 SUPER has 10240 shading units, 320 TMUs, 112 ROPs, 80 ray tracing cores, and 320 tensor cores. The Arc G3's ray tracing implementation is present but limited to 10 cores, while the RTX 4080 SUPER has eight times that count. Tensor cores, which are used for AI-accelerated workloads, are not specified for the Arc G3, while the RTX 4080 SUPER includes 320 of them.

Clock speeds reveal the different design philosophies. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The RTX 4080 SUPER has a base clock of 2295 MHz and a boost clock of 2550 MHz. The Arc G3's wide clock range reflects its power-adaptive nature as an integrated part, while the RTX 4080 SUPER operates at consistently high clocks under its 320 W power envelope.

Memory architecture is another major divergence. The Arc G3 relies on system memory with bandwidth that is dependent on the host system, so its performance scales with the platform it is integrated into. The RTX 4080 SUPER has dedicated 16 GB of GDDR6X memory running at an effective speed of 23 Gbps, delivering 736.3 GB/s of bandwidth over a 256-bit interface. This dedicated memory bandwidth is a decisive advantage for high-resolution texture streaming and compute-heavy workloads.

The physical formats are also distinct. The Arc G3 is an IGP with no slot width, no power connectors, and display outputs that are dependent on the portable device it is embedded in. The RTX 4080 SUPER is a triple-slot card measuring 310 mm in length, 140 mm in height, and 61 mm in width, with outputs including 1x HDMI 2.1 and 3x DisplayPort 1.4a. The RTX 4080 SUPER connects via PCIe 4.0 x16, while the Arc G3 uses the integrated graphics path.

Where Each One Wins

The benchmark data shows a clear separation of use cases. The NVIDIA GeForce RTX 4080 SUPER is the overwhelmingly dominant performer in raw graphics throughput. Its recorded benchmark scores include a 3DMark Steel Nomad DX12 score of 6600, a Geekbench OpenCL score of 219065, a Geekbench Vulkan score of 260075, and a Passmark G3D score of 34245. The Arc G3 has no recorded benchmark scores in the database, meaning its performance cannot be quantified against the RTX 4080 SUPER in any direct comparison.

The RTX 4080 SUPER's strength is in desktop and high-end laptop gaming, content creation, and compute workloads that demand high fill rates and large memory pools. Its 52.22 TFLOPS of FP32 performance and 816.0 GTexel/s texture rate make it suited for 4K gaming and GPU-accelerated rendering. Its 285.6 GPixel/s pixel rate supports high refresh rates at high resolutions.

The Intel Arc G3 wins in a different category: power efficiency and integration. Its 25 W TDP is a fraction of the RTX 4080 SUPER's 320 W TDP. It requires no power connectors and no dedicated power supply. This makes it applicable to portable devices where battery life and thermal constraints are paramount. The Arc G3's performance is system-dependent, so in a thin-and-light laptop with fast LPDDR memory, it can handle light gaming and media tasks, but its capabilities are bounded by the shared memory bandwidth.

The Arc G3 also has the advantage of production status: it is currently active, while the RTX 4080 SUPER has been discontinued. For new system designs targeting ultra-mobile form factors, the Arc G3 is an available option, whereas the RTX 4080 SUPER is limited to existing stock or used markets.

Power and physical specs: the Arc G3 is 25 W, IGP slot width, no power connectors, no suggested PSU, and integrated bus interface. The RTX 4080 SUPER is 320 W, triple-slot, 1x 16-pin connector, 700 W suggested PSU, and PCIe 4.0 x16 interface.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark results between the Intel Arc G3 and the NVIDIA GeForce RTX 4080 SUPER. This is because the Arc G3 has an empty benchmarks array and no nearest rivals listed, while the RTX 4080 SUPER has ten recorded benchmark entries. Direct comparison of their measured performance is therefore not possible from the recorded data.

The RTX 4080 SUPER's standalone scores provide a reference point for its absolute capability. Its 3DMark Steel Nomad DX12 score of 6600 indicates strong DX12 gaming performance. Its Geekbench Vulkan score of 260075 is its highest recorded compute result, suggesting Vulkan-based workloads run particularly well. The Passmark G3D score of 34245 and Passmark GPU Compute score of 19822 show balanced rasterization and compute performance. The Passmark DirectX 11 score of 301 and DirectX 10 score of 193 are legacy API results, while the DirectX 12 score of 134 and DirectX 9 score of 381 round out the profile.

The RTX 4080 SUPER's nearest rivals in the database are all within a narrow margin. The NVIDIA GeForce RTX 4080 has an average score of 54247, which is 0.1% higher than the RTX 4080 SUPER's average of 54209. The AMD Radeon Pro W5700X scores 54828, which is 1.1% above, and the AMD Radeon RX 6750 GRE 12 GB scores 55698, which is 2.7% above. The AMD Radeon 8060S scores 55757, 2.8% above the RTX 4080 SUPER. This clustering indicates that the RTX 4080 SUPER sits at a competitive position within its performance class, slightly behind four direct alternatives in average score.

The percentile rank of the RTX 4080 SUPER is 86 among all GPUs in the database, meaning it outperforms 86% of recorded graphics processors. The Arc G3 has a percentile rank of 50, placing it at the median of the database. This percentile gap, combined with the absence of any measured benchmarks for the Arc G3, suggests that the RTX 4080 SUPER occupies a much higher performance tier.

The Verdict

The recorded data supports a straightforward selection based on use case. For any application that demands high frame rates, high resolutions, or heavy compute throughput, the NVIDIA GeForce RTX 4080 SUPER is the only viable choice between the two. Its 52.22 TFLOPS FP32 performance, 736.3 GB/s memory bandwidth, and 80 ray tracing cores place it in a performance class that the Arc G3 cannot approach based on the available specifications. The RTX 4080 SUPER's 86th percentile ranking among all GPUs confirms its position as a high-end part, and its benchmark scores demonstrate strong DX12, Vulkan, and compute capabilities.

The Intel Arc G3 is the choice for systems where power draw and physical footprint are the limiting factors. Its 25 W TDP, lack of power connectors, and IGP form factor make it suitable for portable devices where a discrete card cannot be installed. Its performance is system dependent, so the actual experience will vary with the host memory and processor. The Arc G3's median percentile rank of 50 indicates it is an average performer in the database, adequate for light workloads but not competitive with the RTX 4080 SUPER in any measured category.

The RTX 4080 SUPER is end-of-life with a launch MSRP of 999 USD, while the Arc G3 is active and has no launch MSRP recorded. Buyers seeking a new high-performance desktop GPU must look elsewhere, as the RTX 4080 SUPER is no longer in production. Buyers designing new ultra-portable devices can source the Arc G3 as an integrated solution.

The absence of head-to-head benchmark data means the performance gap cannot be quantified directly, but the specification differences are decisive. The RTX 4080 SUPER has eight times the shading units, eight times the RT cores, and more than eight times the FP32 throughput of the Arc G3. Its memory bandwidth is orders of magnitude higher than any system shared configuration. For gaming, rendering, or compute, the RTX 4080 SUPER is the superior product. For battery-powered, fanless, or space-constrained designs, the Arc G3 is the only applicable option. The choice is not about which is faster, but about which fits the system.
