Intel Arc G3 Extreme vs NVIDIA RTX A400 Comparison

The Verdict

The database comparison between the Intel Arc G3 Extreme and the NVIDIA RTX A400 reveals two fundamentally different products aimed at distinct use cases. The Intel Arc G3 Extreme is an integrated graphics processor within the Panther Lake chip, built on a 3 nm process, while the NVIDIA RTX A400 is a discrete workstation card based on the Ampere architecture. The Arc G3 Extreme carries a higher theoretical throughput profile across raw shading, texturing, and pixel output, while the RTX A400 delivers dedicated memory and a compact single-slot form factor.

For users prioritizing raw compute throughput in a mobile or integrated context, the Arc G3 Extreme shows significantly higher specifications: 7.680 TFLOPS FP32 versus 2.706 TFLOPS, 1536 shading units against 768, and 48 texture mapping units versus 24. The Arc G3 Extreme also doubles the pixel rate at 60.00 GPixel/s compared to 28.19 GPixel/s. However, the RTX A400 counters with dedicated 4 GB GDDR6 memory on a 64-bit bus delivering 96.00 GB/s, whereas the Arc G3 Extreme relies on system shared memory with bandwidth described as system dependent.

The RTX A400 holds a percentile rank of 35 among all GPUs in the database, with an average benchmark score of 6078. Its nearest rivals include the NVIDIA GeForce MX230 at 6077, the NVIDIA Quadro P2000 at 6049, the Intel Iris Pro Graphics 6200 at 6117, and the AMD Radeon 760M at 6019. The delta percentages place the RTX A400 essentially level with these peers, within a range of -0.6% to 1%. The Arc G3 Extreme has no recorded benchmark scores, no average score, and no nearest rivals in the database, so its real-world performance cannot be quantified here.

The verdict from the recorded data: the Arc G3 Extreme suits users who need maximum integrated graphics throughput with modern API support, while the RTX A400 suits users who require a dedicated, low-profile workstation card with stable driver validation and existing benchmark evidence. Neither product defeats the other outright; they occupy separate segments, and the choice depends on whether the workload runs on an integrated platform or a discrete PCIe card.

Architecture Differences

The Intel Arc G3 Extreme uses the Panther Lake chip with the Xe3-LPG architecture, classified under the Arc Graphics-M generation. It is fabricated on a 3 nm process at Intel's foundry. The die size, transistor count, and transistor density are not recorded in the database. The architecture implements 12 ray tracing cores, though no tensor core count is listed. The design is an integrated graphics processor, meaning it shares system memory and has no dedicated VRAM.

The NVIDIA RTX A400 uses the GA107 chip with the Ampere architecture, part of the Workstation Ampere generation. It is fabricated on an 8 nm process at Samsung. The die size is 200 mm² with 8,700 million transistors, yielding a transistor density of 43.5M per mm². The architecture includes 6 ray tracing cores and 24 tensor cores, which distinguishes it from the Arc G3 Extreme's ray tracing-only setup. The RTX A400 is a discrete card with its own 4 GB GDDR6 memory.

The manufacturing process difference is substantial: 3 nm versus 8 nm. The Arc G3 Extreme's smaller node allows higher clock headroom and density, but the database does not record its transistor count. The RTX A400's larger node is offset by a dedicated memory subsystem and tensor core support. Both GPUs support the same API levels: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RTX A400's predecessor is the Quadro Turing, and its successor is Workstation Ada, while the Arc G3 Extreme has no listed predecessor or successor.

The Arc G3 Extreme's integrated nature means its memory performance depends entirely on the host system, whereas the RTX A400's GDDR6 provides fixed bandwidth. The RTX A400 also includes a PCIe 4.0 x8 interface, while the Arc G3 Extreme uses an IGP bus interface with no expansion slot requirement.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc G3 Extreme and the NVIDIA RTX A400. The Arc G3 Extreme has an empty benchmarks array, no average score, and a percentile rank of 50. The RTX A400 has nine recorded benchmark entries and a percentile rank of 35.

For the RTX A400, the recorded scores show a wide spread across test types. The Geekbench OpenCL score is 22844, and the Geekbench Vulkan score is 22237. In Passmark tests, the DirectX 9 score is 87, DirectX 10 is 32, DirectX 11 is 37, and DirectX 12 is 27. The G2D score is 899, the G3D score is 5983, and the GPU compute score is 2557. These figures indicate that the RTX A400 performs strongest in compute-oriented workloads and significantly weaker in older DirectX rasterization tests.

The Arc G3 Extreme's theoretical specifications suggest it should outperform the RTX A400 in raw shading and texturing. The FP32 throughput of 7.680 TFLOPS is roughly 2.8 times the RTX A400's 2.706 TFLOPS. The texture rate of 120.0 GTexel/s is about 2.8 times the RTX A400's 42.29 GTexel/s. The pixel rate of 60.00 GPixel/s is about 2.1 times the RTX A400's 28.19 GPixel/s. The Arc G3 Extreme also has double the shading units, double the TMUs, and 50% more ROPs.

However, the RTX A400 counters with higher base and boost clocks. Its base clock of 1417 MHz is over 4.7 times the Arc G3 Extreme's 300 MHz base, and its boost clock of 1762 MHz is lower than the Arc G3 Extreme's 2500 MHz boost. The RTX A400's dedicated 96.00 GB/s bandwidth exceeds the system dependent bandwidth of the Arc G3 Extreme, which cannot be quantified without a specific host platform.

The RTX A400's nearest rivals provide context for its recorded performance. With an average score of 6078, it sits within 0.6% below the Intel Iris Pro Graphics 6200 at 6117, within 0.5% above the Quadro P2000 at 6049, within 0% of the GeForce MX230 at 6077, and within 1% above the Radeon 760M at 6019. This cluster of results suggests the RTX A400 delivers performance consistent with entry-level discrete GPUs.

No wins are recorded for either side in the head-to-head field. The Arc G3 Extreme has zero benchmark entries, so its percentile rank of 50 reflects a placement based on specifications rather than measured results. The RTX A400's percentile rank of 35 places it below the median of all GPUs in the database. The data indicates that the Arc G3 Extreme's integrated design offers substantially higher theoretical throughput, but the RTX A400's existing benchmark scores demonstrate measurable performance across multiple test suites. The absence of Arc G3 Extreme benchmark data prevents a definitive performance comparison, leaving the RTX A400 as the only product with empirical evidence in the database.
