Intel Arc G3 vs NVIDIA GeForce RTX 4080 Max-Q Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the Intel Arc G3 and the NVIDIA GeForce RTX 4080 Max-Q. The winsA and winsB counters are both at zero, meaning neither part has an established performance victory in direct comparisons. The avgBenchmarkScore for both entries is 0, and the percentileVsAllGpus field sits at 50 for each, placing both in the median position of the overall GPU distribution according to the recorded data.

This absence of measured results is notable because the two parts occupy very different positions in the product stack. The Intel Arc G3 is an integrated graphics processor built for the Panther Lake mobile platform, with a 25 W TDP and a 300 MHz base clock that boosts to 2400 MHz. The NVIDIA GeForce RTX 4080 Max-Q is a dedicated mobile GPU in the GeForce 40-series, with a 60 W TDP, a 795 MHz base clock, and a 1350 MHz boost clock. Without direct benchmark scores, the only quantitative comparison available comes from the raw specification fields.

The RTX 4080 Max-Q delivers 20.04 TFLOPS of FP32 compute, while the Arc G3 provides 6.144 TFLOPS. That is a 3.26x difference in raw floating-point throughput. The NVIDIA part also produces 108.0 GPixel/s of pixel fill rate versus 48.00 GPixel/s for the Intel part, a 2.25x advantage. Texture rate shows an even wider gap: 313.2 GTexel/s for the RTX 4080 Max-Q versus 96.00 GTexel/s for the Arc G3, a 3.26x difference that mirrors the FP32 ratio. These figures indicate that in any compute-bound or fill-rate-bound workload, the NVIDIA part would likely dominate, but the absence of actual benchmark runs means the database cannot confirm this with measured scores.

The Verdict

The recorded data supports only one clear conclusion: the RTX 4080 Max-Q is positioned to outperform the Arc G3 in nearly every measurable metric. The FP32 throughput advantage of 20.04 TFLOPS versus 6.144 TFLOPS, the pixel rate advantage of 108.0 GPixel/s versus 48.00 GPixel/s, and the texture rate advantage of 313.2 GTexel/s versus 96.00 GTexel/s all point in the same direction. The RTX 4080 Max-Q also carries 12 GB of dedicated GDDR6 memory with a 192-bit bus and 432.0 GB/s of bandwidth, while the Arc G3 relies on system-shared memory with bandwidth that the database lists as system dependent. For any application that stresses dedicated video memory, the NVIDIA part has an inherent structural advantage.

The Arc G3 does hold advantages in specific areas. Its 300 MHz base clock is lower than the RTX 4080 Max-Q's 795 MHz, but the Intel part boosts to 2400 MHz, which is 1050 MHz higher than the NVIDIA part's 1350 MHz boost. The Arc G3 also has a much lower TDP at 25 W versus 60 W, and it requires no power connectors, matching the RTX 4080 Max-Q in that regard. For systems where power draw is the limiting factor, the Intel part is the more efficient choice on paper. However, the database has no efficiency benchmarks, so this remains a specification-level observation rather than a measured result.

The percentileVsAllGpus value of 50 for both parts suggests the database places them equivalently in the overall distribution, but this is likely a placeholder given the zero average benchmark scores. Users should treat the percentile field with caution until actual benchmark data populates the entries. The verdict from available data: the RTX 4080 Max-Q is the stronger performer, while the Arc G3 offers a lower-power integrated alternative with a notably higher boost clock.

Architecture Differences

The two GPUs come from different architectural lineages. The Intel Arc G3 uses the Xe3-LPG architecture built on the Panther Lake chip, fabricated on a 3 nm process at Intel's own foundry. The NVIDIA GeForce RTX 4080 Max-Q uses the Ada Lovelace architecture with the AD104 chip, fabricated on a 5 nm process at TSMC. The process node difference is significant: 3 nm versus 5 nm suggests the Intel part uses a more advanced lithography, though the transistor counts tell a different story. The RTX 4080 Max-Q packs 35,800 million transistors on a 294 mm² die, yielding a transistor density of 121.8M per mm². The Arc G3's transistor count and die size are listed as unknown, so no density comparison is possible.

The RTX 4080 Max-Q includes 58 RT cores and 232 tensor cores, while the Arc G3 has 10 RT cores and no tensor core count listed. This disparity in dedicated hardware suggests the NVIDIA part is designed for heavier ray tracing and AI-accelerated workloads. The shading unit counts reinforce this: the RTX 4080 Max-Q has 7424 shading units, 232 texture mapping units, and 80 raster operation units, versus the Arc G3's 1280 shading units, 40 TMUs, and 20 ROPs. The NVIDIA part has 58 times more RT cores, 5.8 times more shading units, 5.8 times more TMUs, and 4 times more ROPs. These are structural differences that affect how each GPU handles geometry, lighting, and post-processing effects.

The Arc G3 is an integrated graphics processor, meaning it shares system memory and has no dedicated VRAM. The RTX 4080 Max-Q is also listed with an IGP slot width and no power connectors, but it carries its own 12 GB GDDR6 memory. This makes the NVIDIA part a discrete solution despite the IGP form factor notation. The front-end architecture also differs: the RTX 4080 Max-Q uses PCIe 4.0 x16 as its bus interface, while the Arc G3 uses an integrated bus interface with no external connection. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level compatibility is identical.

Specification Differences

The two parts differ across nearly every specification field. Clock speeds show the most interesting inversion: the Arc G3 has a 300 MHz base clock and a 2400 MHz boost, while the RTX 4080 Max-Q has a 795 MHz base and a 1350 MHz boost. The Intel part boosts 1050 MHz higher, but the NVIDIA part starts from a much higher base. Memory configurations are fundamentally different: the Arc G3 uses system-shared memory with a system-shared bus width and system-dependent bandwidth, while the RTX 4080 Max-Q uses 12 GB of GDDR6 with a 192-bit bus and 432.0 GB/s bandwidth. The memory clock field lists 2250 MHz with 18 Gbps effective for the NVIDIA part, while the Arc G3's memory clock is system shared.

Compute resources differ by multiples: shading units at 1280 versus 7424, TMUs at 40 versus 232, ROPs at 20 versus 80, RT cores at 10 versus 58. The tensor core count is null for the Arc G3 and 232 for the RTX 4080 Max-Q. Pixel rate is 48.00 GPixel/s versus 108.0 GPixel/s, and texture rate is 96.00 GTexel/s versus 313.2 GTexel/s. FP32 compute is 6.144 TFLOPS versus 20.04 TFLOPS. FP16 shows a notable difference in ratio: the Arc G3 delivers 12.29 TFLOPS at a 2:1 ratio, while the RTX 4080 Max-Q delivers 20.04 TFLOPS at a 1:1 ratio. This means the NVIDIA part does not gain a throughput boost from FP16, whereas the Intel part doubles its rate.

Power draw is another divergence: 25 W for the Arc G3 versus 60 W for the RTX 4080 Max-Q. Both have no power connectors and an IGP slot width. The process node is 3 nm for Intel and 5 nm for NVIDIA, and the foundry differs as Intel versus TSMC. The release dates are far apart: the RTX 4080 Max-Q launched on 2023-01-02, while the Arc G3 is dated 2026-05-31. The RTX 4080 Max-Q has a predecessor in GeForce 30 Mobile and a successor in GeForce 50 Mobile, while the Arc G3 has neither predecessor nor successor listed. Display outputs are portable device dependent for both, and dimensions are null for both.

Where Each One Wins

The RTX 4080 Max-Q wins in every compute and memory metric recorded in the database. Its 20.04 TFLOPS FP32 throughput is 3.26 times the Arc G3's 6.144 TFLOPS, making it the clear choice for raw compute workloads. The pixel rate of 108.0 GPixel/s versus 48.00 GPixel/s gives it a 2.25x advantage in fill-rate-bound scenarios. The texture rate of 313.2 GTexel/s versus 96.00 GTexel/s provides a 3.26x advantage in texture-heavy rendering. The 12 GB GDDR6 memory with 432.0 GB/s bandwidth versus system-shared memory gives it a decisive edge in any workload that benefits from dedicated, high-bandwidth VRAM. The 58 RT cores versus 10 RT cores and 232 tensor cores versus none suggest the NVIDIA part is better suited for ray tracing and tensor-accelerated tasks.

The Arc G3 wins in power efficiency and clock headroom. Its 25 W TDP is less than half the RTX 4080 Max-Q's 60 W, making it the lower-power option for thermally constrained systems. Its 2400 MHz boost clock is 1050 MHz higher than the NVIDIA part's 1350 MHz, which could translate to advantages in latency-sensitive or lightly threaded workloads where raw clock speed matters more than parallel throughput. The 3 nm process node from Intel's foundry is smaller than the 5 nm TSMC node used by NVIDIA, potentially offering better power efficiency per transistor, though the database does not provide efficiency benchmarks to confirm this.

The Arc G3 also wins on integration: it uses system-shared memory, which removes the need for dedicated VRAM allocation and simplifies system design. The RTX 4080 Max-Q, despite its IGP slot width, requires its own 12 GB GDDR6 memory, adding cost and complexity. For systems where the CPU and GPU share memory resources, the Arc G3's architecture is more unified. The database shows no benchmark wins for either part, so these conclusions rest entirely on specification differences. The RTX 4080 Max-Q is the performance leader across all measured throughput metrics, while the Arc G3 offers lower power draw, a higher boost clock, and a more integrated memory model.
