Intel Arc G3 vs NVIDIA GeForce RTX 4080 Mobile Comparison

Head-to-Head Benchmarks

The recorded database contains no head-to-head benchmark entries for the Intel Arc G3 versus the NVIDIA GeForce RTX 4080 Mobile. The Intel Arc G3 has no benchmark scores listed, while the RTX 4080 Mobile has nine recorded test scores. The absence of direct comparison data means every performance differential must be derived from the available RTX 4080 Mobile scores and the architectural specifications of both parts.

The RTX 4080 Mobile delivers a Geekbench OpenCL score of 159575 and a Geekbench Vulkan score of 145807. In Passmark testing, the GPU records 24926 in G3D, 11191 in GPU compute, 929 in G2D, 286 in DirectX 9, 244 in DirectX 11, 157 in DirectX 10, and 96 in DirectX 12. The average benchmark score across all recorded tests is 38135, placing the RTX 4080 Mobile at the 81st percentile among all GPUs in the database.

The Intel Arc G3 has no recorded scores in any test and sits at the 50th percentile with an average benchmark score of zero. This percentile figure indicates the database treats it as having no measurable performance data, not that it performs at the median level. The Arc G3’s specifications suggest it targets a different performance class entirely. Its FP32 throughput is 6.144 TFLOPS, its pixel rate is 48.00 GPixel/s, and its texture rate is 96.00 GTexel/s. The RTX 4080 Mobile delivers 24.72 TFLOPS FP32, 133.2 GPixel/s pixel rate, and 386.3 GTexel/s texture rate. The RTX 4080 Mobile is 4.02 times higher in FP32, 2.78 times higher in pixel rate, and 4.02 times higher in texture rate.

The RTX 4080 Mobile’s nearest rivals in the database include the NVIDIA GeForce MX570 with an average score of 38299 and a delta of -0.4 percent, the NVIDIA GeForce RTX 5080 Mobile at 38349 with a delta of -0.6 percent, the NVIDIA GeForce RTX 4070 at 37648 with a delta of 1.3 percent, and the NVIDIA Tesla P4 at 37628 with a delta of 1.3 percent. These deltas show the RTX 4080 Mobile sits within a tight cluster. It trails the MX570 by 0.4 percent and the RTX 5080 Mobile by 0.6 percent, while leading the RTX 4070 and Tesla P4 by 1.3 percent each. The RTX 4080 Mobile’s average score of 38135 is remarkably close to the MX570’s 38299, a difference of only 164 points.

The Arc G3 uses system shared memory with system dependent bandwidth, whereas the RTX 4080 Mobile has 12 GB of GDDR6 on a 192-bit bus delivering 432.0 GB/s. The memory bandwidth gap is structural: the Arc G3’s bandwidth cannot be quantified independently, but the RTX 4080 Mobile’s dedicated 432.0 GB/s is a fixed resource. The Arc G3’s boost clock of 2400 MHz exceeds the RTX 4080 Mobile’s 1665 MHz boost, but the RTX 4080 Mobile compensates with 7424 shading units versus 1280, 232 texture mapping units versus 40, 80 raster output units versus 20, and 58 ray tracing cores versus 10. The RTX 4080 Mobile also has 232 tensor cores while the Arc G3 lists none.

The Verdict

The data indicates the NVIDIA GeForce RTX 4080 Mobile is the overwhelmingly faster GPU in every measurable category. Its FP32 throughput of 24.72 TFLOPS is four times the Arc G3’s 6.144 TFLOPS. Its pixel rate of 133.2 GPixel/s is 2.78 times the Arc G3’s 48.00 GPixel/s. Its texture rate of 386.3 GTexel/s is 4.02 times the Arc G3’s 96.00 GTexel/s. The RTX 4080 Mobile’s 12 GB of GDDR6 memory with 432.0 GB/s bandwidth is a discrete memory subsystem, while the Arc G3 relies on system shared memory with system dependent bandwidth.

The RTX 4080 Mobile’s 81st percentile ranking versus the Arc G3’s 50th percentile ranking confirms the hierarchy. The RTX 4080 Mobile’s average benchmark score of 38135 places it among capable mobile GPUs, while the Arc G3 has no recorded average score. Any user requiring compute throughput, ray tracing performance, or memory bandwidth should select the RTX 4080 Mobile based strictly on the recorded specifications.

The Arc G3 offers a lower thermal envelope at 25 W versus 110 W, and a higher boost clock at 2400 MHz versus 1665 MHz. Its 3 nm process node from Intel is smaller than the RTX 4080 Mobile’s 5 nm TSMC node. These factors matter only for power-constrained designs or die-size comparisons, not for raw performance. The Arc G3’s 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores are all substantially below the RTX 4080 Mobile’s 7424, 232, 80, and 58 respectively.

The RTX 4080 Mobile’s nearest rival data shows it performs within 1.3 percent of the RTX 4070 and Tesla P4, and within 0.6 percent of the RTX 5080 Mobile. The Arc G3 has no rival data, so no comparative performance statement is possible. The verdict is unambiguous: the RTX 4080 Mobile is the only choice for performance-sensitive workloads, while the Arc G3 is positioned for low-power integrated use where its 25 W TDP and system shared memory are acceptable.
