Intel Arc G3 Extreme vs NVIDIA GeForce RTX 5080 SUPER Comparison

Intel Arc G3 Extreme vs NVIDIA GeForce RTX 5080 SUPER

Head-to-Head Benchmarks

The recorded data presents a stark contrast between these two GPUs. The NVIDIA GeForce RTX 5080 SUPER has a single benchmark entry in the database: a 3DMark Steel Nomad DX12 score of 3075. The Intel Arc G3 Extreme currently has no benchmark scores recorded, meaning a direct numerical comparison in the same test is impossible. The database shows the RTX 5080 SUPER holds an average benchmark score of 3075, placing it in the 19th percentile of all GPUs. Its nearest rivals in the database include the Intel Arc Pro B60 with an average score of 3182, which is 3.4% higher, and the NVIDIA Quadro P1000 with 3163, which is 2.8% higher. The RTX 5080 SUPER outperforms the NVIDIA GeForce 820A (2983) by 3.1% and the NVIDIA GeForce GTX 860M (2967) by 3.6%. For the Arc G3 Extreme, the database records a 50th percentile ranking among all GPUs, but without a benchmark score, its relative performance cannot be quantified against the RTX 5080 SUPER directly.

The raw compute specifications, however, reveal a massive gap in theoretical performance. The RTX 5080 SUPER delivers 56.28 TFLOPS of FP32 compute, while the Arc G3 Extreme provides 7.680 TFLOPS. This represents a 7.3x advantage for the NVIDIA part in raw shader throughput. The RTX 5080 SUPER also leads in pixel fill rate at 293.1 GPixel/s versus 60.00 GPixel/s, and in texture rate at 879.3 GTexel/s versus 120.0 GTexel/s. These figures indicate the RTX 5080 SUPER is designed for high-resolution rendering and heavy texture workloads, while the Arc G3 Extreme targets a fundamentally different performance class.

The RTX 5080 SUPER's memory subsystem is a clear differentiator. It features 24 GB of GDDR7 memory on a 256-bit bus, delivering 1.02 TB/s of bandwidth. The Arc G3 Extreme uses system shared memory, with bandwidth described as "System Dependent." This means the Intel part's memory performance is entirely contingent on the host platform, whereas the NVIDIA card has a dedicated, high-bandwidth pool. The RTX 5080 SUPER's memory clock is 2000 MHz with 32 Gbps effective speed, a fixed specification, while the Arc G3 Extreme's memory clock is also "System Shared."

The Verdict

The data indicates these are not competing products in any meaningful sense. The NVIDIA GeForce RTX 5080 SUPER is a high-end discrete graphics card with a 415 W TDP, a dual-slot cooler, and a 304 mm length. It requires a PCIe 5.0 x16 slot and a 16-pin power connector. The Intel Arc G3 Extreme is an integrated graphics processor (IGP) with an 80 W TDP, no power connectors, and a slot width of "IGP," meaning it is embedded in a processor package. Its bus interface is also "IGP," confirming it is not a standalone card.

The RTX 5080 SUPER is the only one with a recorded benchmark score. Its 3DMark Steel Nomad DX12 result of 3075 places it below the Intel Arc Pro B60 and NVIDIA Quadro P1000 in the database's nearest rival list, despite its enormous theoretical compute advantage. This suggests that the benchmark result may be from a specific configuration or workload where these other GPUs perform relatively well. The Arc G3 Extreme has no such data, so any performance conclusion about it must rely on its architectural specifications alone.

For a user seeking a dedicated, high-performance GPU with substantial VRAM and bandwidth, the RTX 5080 SUPER is the only option with recorded performance data. The Arc G3 Extreme, as an integrated solution, is designed for systems where a discrete card is not feasible. Its 80 W TDP and lack of a power connector indicate it is intended for low-power or portable devices. The RTX 5080 SUPER, with a launch MSRP of 999 USD, is a premium product. The database does not record a launch MSRP for the Arc G3 Extreme.

Specification Differences

The two GPUs differ across nearly every measurable specification. The RTX 5080 SUPER uses NVIDIA's Blackwell 2.0 architecture on a 5 nm TSMC process, with a chip designated GB203. The Arc G3 Extreme uses Intel's Xe3-LPG architecture on a 3 nm process, with a chip designated Panther Lake. The RTX 5080 SUPER has 45,600 million transistors on a 378 mm² die with a transistor density of 120.6M per mm². The Arc G3 Extreme's transistor count and die size are unknown.

Clock speeds differ significantly. The RTX 5080 SUPER has a base clock of 2295 MHz and a boost clock of 2617 MHz. The Arc G3 Extreme has a base clock of 300 MHz and a boost clock of 2500 MHz. The NVIDIA card's memory clock is 2000 MHz with 32 Gbps effective speed, while the Intel part's memory clock is "System Shared."

The RTX 5080 SUPER features 10752 shading units, 336 TMUs, 112 ROPs, 84 RT cores, and 336 tensor cores. The Arc G3 Extreme has 1536 shading units, 48 TMUs, 24 ROPs, and 12 RT cores, with no tensor core count listed. Pixel rate is 293.1 GPixel/s for NVIDIA and 60.00 GPixel/s for Intel. Texture rate is 879.3 GTexel/s versus 120.0 GTexel/s.

Physical and power specifications are also divergent. The RTX 5080 SUPER is a dual-slot card measuring 304 mm in length, 137 mm in height, and 40 mm in width. It uses a 1x 16-pin power connector and has a 415 W TDP. The Arc G3 Extreme has a slot width of "IGP," no power connectors, and an 80 W TDP. The NVIDIA card uses a PCIe 5.0 x16 bus interface, while the Intel part uses "IGP." Display outputs are 1x HDMI 2.1b and 3x DisplayPort 2.1b for NVIDIA, and "Portable Device Dependent" for Intel.

Architecture Differences

The architectural divide is fundamental. The RTX 5080 SUPER is built on NVIDIA's Blackwell 2.0 architecture, fabricated by TSMC on a 5 nm process. It is a discrete GPU with a dedicated memory interface and a full array of specialized hardware. The Arc G3 Extreme is based on Intel's Xe3-LPG architecture, fabricated by Intel on a 3 nm process. It is an integrated graphics processor, meaning it shares system memory and is embedded within a larger processor package.

The RTX 5080 SUPER includes 84 RT cores and 336 tensor cores, making it a fully featured ray tracing and AI accelerator. The Arc G3 Extreme has 12 RT cores and no tensor core count specified. The NVIDIA part's FP16 performance is 56.28 TFLOPS at a 1:1 ratio, matching its FP32 output. The Intel part's FP16 is 15.36 TFLOPS at a 2:1 ratio, meaning it half-rate for FP16 work.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX 5080 SUPER's memory subsystem is dedicated GDDR7, while the Arc G3 Extreme relies on system memory, making its performance dependent on the host platform's RAM and memory controller. The RTX 5080 SUPER's transistor density of 120.6M per mm² indicates a dense design, while the Arc G3 Extreme's density is unknown. The 3 nm process for Intel versus the 5 nm process for NVIDIA suggests a potentially higher transistor density potential for the Intel part, but without transistor count data, this cannot be confirmed.

Where Each One Wins

The RTX 5080 SUPER wins in every recorded performance metric. It has a benchmark score of 3075 in 3DMark Steel Nomad DX12, while the Arc G3 Extreme has none. The NVIDIA card's FP32 compute is 56.28 TFLOPS versus 7.680 TFLOPS, its pixel rate is 293.1 GPixel/s versus 60.00 GPixel/s, and its texture rate is 879.3 GTexel/s versus 120.0 GTexel/s. It has more shading units, TMUs, ROPs, RT cores, and tensor cores. Its 24 GB of GDDR7 memory with 1.02 TB/s bandwidth is a decisive advantage for large datasets and high-resolution textures.

The Arc G3 Extreme wins in power efficiency and physical footprint. Its 80 W TDP is drastically lower than the RTX 5080 SUPER's 415 W. It has no power connectors and an IGP slot width, meaning it can be integrated into compact or portable devices without the need for a discrete power supply or expansion slot. Its 3 nm process node is smaller than the NVIDIA part's 5 nm node, potentially offering a manufacturing advantage in terms of density, though the Arc G3 Extreme's transistor count is unknown.

For a desktop workstation or gaming rig requiring maximum performance, the RTX 5080 SUPER is the clear choice based on the available data. It offers dedicated memory, high bandwidth, and a full suite of ray tracing and tensor cores. The Arc G3 Extreme is suited for systems where power draw and space are constrained, such as portable devices or embedded applications. Its system shared memory and IGP bus interface limit its peak performance but enable a minimal physical footprint. The database shows the RTX 5080 SUPER is in the 19th percentile of all GPUs, while the Arc G3 Extreme is in the 50th percentile, but without benchmark scores for the Intel part, these percentiles cannot be directly compared in terms of actual performance.
