AMD Radeon 8040S vs Intel Arc G3 Extreme Comparison

AMD Radeon 8040S and Intel Arc G3 Extreme are both integrated graphics solutions, but they cater to different performance tiers and platform philosophies. The Radeon 8040S, built on Strix Halo silicon, is an established part with a full set of recorded benchmark data. The Arc G3 Extreme, based on Panther Lake, is newer and has no recorded benchmark scores in the database, which places it in a different analytical position. The following analysis relies solely on the recorded specifications and available benchmark metrics to compare the two.

Where Each One Wins

The AMD Radeon 8040S wins in any scenario where existing measured performance data is required. It has a complete set of PassMark benchmark results, including DirectX 9, 10, 11, 12, G2D, G3D, and GPU compute scores. Its average benchmark score is 2440, and it sits at the 17th percentile of all GPUs. The Intel Arc G3 Extreme has no benchmark results recorded, meaning it cannot claim a single measured performance win in the database.

The Intel Arc G3 Extreme wins on raw architectural throughput potential based on its specifications. It delivers 7.680 TFLOPS of FP32 compute, which is higher than the AMD part's 5.734 TFLOPS. It also supports FP16 at a 2:1 ratio, reaching 15.36 TFLOPS, whereas the Radeon 8040S offers FP16 at a 1:1 ratio, capping at 5.734 TFLOPS. In tasks that can leverage half-precision arithmetic, the Intel part has a distinct theoretical advantage.

The Radeon 8040S wins on power efficiency relative to its measured output. It is rated at 55 W TDP and achieves a G3D score of 10578. The Arc G3 Extreme is rated at 80 W TDP, a higher power draw, with no measured score to compare against. For systems where the integrated GPU must share thermal and power budgets with the CPU, the lower TDP of the Radeon part is a practical advantage.

Architecture Differences

The AMD Radeon 8040S uses the RDNA 3.5 architecture on a 4 nm process from TSMC. It is part of the Navi Mobile (RX 8000M) generation and is built on the Strix Halo chip. The die size is 308 mm². The Intel Arc G3 Extreme uses the Xe3-LPG architecture on a 3 nm process from Intel's own foundry, based on the Panther Lake chip, within the Arc Graphics-M (Panther Lake) generation.

The two differ significantly in execution resource allocation. The Radeon 8040S has 1024 shading units, 64 texture mapping units, and 32 raster output pipelines. The Arc G3 Extreme has 1536 shading units, which is 50% more, but only 48 TMUs and 24 ROPs, which are lower counts than the AMD part. The AMD GPU also has more ray tracing cores: 16 compared to 12 on the Intel part.

Clock speeds show a notable divergence. The Radeon 8040S has a base clock of 1295 MHz and a boost clock of 2800 MHz. The Arc G3 Extreme has a much lower base clock of 300 MHz but a boost clock of 2500 MHz. The large gap between base and boost on the Intel part suggests a more aggressive power management curve, while the AMD part runs at a higher sustained baseline frequency.

Memory architecture is identical in concept: both use System Shared memory, with system-dependent bandwidth. Neither has dedicated VRAM, and both rely on the host system's memory controller. The bus interface differs: the AMD part uses PCIe 5.0 x16, while the Intel part is listed as IGP, indicating a direct integration with the processor package.

Head-to-Head Benchmarks

There are no head-to-head benchmark results in the database for these two GPUs. The AMD Radeon 8040S has its own benchmark suite, while the Intel Arc G3 Extreme has none. This makes a direct numerical comparison impossible based on measured data. The only available comparisons come from the Radeon's nearest rivals list, which does not include the Intel part.

The Radeon 8040S's recorded scores are as follows: PassMark DirectX 9 at 134, DirectX 10 at 48, DirectX 11 at 80, DirectX 12 at 47, G2D at 1052, G3D at 10578, and GPU compute at 5138. Its average benchmark score is 2440. It is 0.3% ahead of the NVIDIA GeForce 710M, 0.6% ahead of the Intel HD Graphics 610, 0.7% ahead of the NVIDIA GeForce GT 710M, and 1.1% behind the AMD Radeon RX 7400.

The Arc G3 Extreme's theoretical output is higher in FP32 and FP16, but without benchmark scores, the database records no wins for it in any test. The Radeon 8040S wins all recorded benchmark comparisons by default, as it is the only one with data. The Intel part's percentile rank is listed at 50, which is higher than the AMD part's 17, but this figure is not supported by any measured scores in the database.

The Verdict

The data indicates a clear split between measured reality and theoretical capability. The AMD Radeon 8040S is the only one of the two with recorded performance data. Its average benchmark score of 2440 places it in the 17th percentile of all GPUs, and its closest rival, the NVIDIA GeForce 710M, is only 0.3% behind. This is a low-end integrated part by measured standards, suitable for basic graphics tasks and light gaming at best.

The Intel Arc G3 Extreme presents a different case. Its specifications suggest a more capable compute unit, with 1536 shading units and 7.680 TFLOPS of FP32, but there is no measured data to confirm how these translate into real-world performance. Its 80 W TDP is higher, and its base clock of 300 MHz is unusually low, which could mean it relies heavily on boost behavior. Without benchmark scores, any performance claim for this part remains speculative.

For a system builder who needs verified performance numbers, the Radeon 8040S is the only option with evidence in the database. Its 10578 G3D score and 5138 GPU compute score provide a baseline for expected behavior. The Arc G3 Extreme, with its higher theoretical FP32 and FP16 output, may offer more compute headroom in workloads that scale with shading units, but the database records no wins for it in any test.

The choice depends on whether the requirement is for measured, existing performance or for higher theoretical throughput in a newer platform. The Radeon 8040S is the proven quantity, while the Arc G3 Extreme is an unverified specification sheet with a higher ceiling on paper.
