Intel Arc G3 vs NVIDIA RTX A400 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Intel Arc G3 and the NVIDIA RTX A400, so the comparison relies on the recorded performance data for the RTX A400 and the architectural specifications of the Arc G3. The RTX A400 has a substantial set of measured scores across nine different tests, while the Arc G3 has no benchmark entries in the database.

The RTX A400's strongest recorded result is in Geekbench OpenCL, where it scores 22,844, with its Geekbench Vulkan result close behind at 22,237. These two tests dominate its performance profile, indicating strong compute and graphics API throughput. In Passmark tests, the RTX A400 shows a varied pattern: DirectX 9 scores 87, DirectX 11 scores 37, DirectX 10 scores 32, and DirectX 12 scores 27. The 2D graphics score is 899, the 3D graphics score is 5,983, and the GPU compute score is 2,557.

The RTX A400's average benchmark score is 6,078, placing it in the 35th percentile of all GPUs in the database. Its nearest rivals in the database are the NVIDIA GeForce MX230 with an average score of 6,077 (0% delta), the NVIDIA Quadro P2000 at 6,049 (0.5% ahead of the RTX A400), the Intel Iris Pro Graphics 6200 at 6,117 (0.6% behind the RTX A400), and the AMD Radeon 760M at 6,019 (1% ahead of the RTX A400). These deltas are all within one percent, indicating that the RTX A400 sits in an extremely tight cluster of comparable performance.

Without recorded benchmarks for the Arc G3, the data cannot confirm any wins for either side in direct testing. The RTX A400's percentile rank of 35 versus the Arc G3's percentile rank of 50 suggests the Arc G3 is positioned higher in the overall distribution, but this ranking is not supported by any measured scores in the database for the Arc G3.

Architecture Differences

The two GPUs come from different manufacturers and use fundamentally different underlying designs. The Intel Arc G3 is built on the Xe3-LPG architecture with the Panther Lake chip, fabricated on a 3 nm process at Intel's own foundry. The NVIDIA RTX A400 uses the Ampere architecture with the GA107 chip, fabricated on an 8 nm process at Samsung. The process node difference is substantial: 3 nm versus 8 nm, which typically allows for higher transistor density and lower power consumption per unit of performance.

The RTX A400 has known physical characteristics: 8,700 million transistors on a 200 mm² die, giving a transistor density of 43.5 million per square millimeter. The Arc G3's transistor count and die size are listed as unknown, so a direct density comparison is not possible from the data.

Clock speeds differ significantly. The Arc G3 has a base clock of 300 MHz and a boost clock of 2,400 MHz. The RTX A400 has a base clock of 1,417 MHz and a boost clock of 1,762 MHz. The Arc G3's boost clock is substantially higher, but the RTX A400's base clock is much higher, reflecting different power and thermal design points.

Memory architecture is a major differentiator. The Arc G3 uses system shared memory, meaning it has no dedicated VRAM and relies on the host system's memory. Its memory type, bus width, and bandwidth are all listed as system dependent. The RTX A400 has 4 GB of dedicated GDDR6 memory on a 64-bit bus, with a bandwidth of 96.00 GB/s and a memory clock of 1,500 MHz (12 Gbps effective). The RTX A400's dedicated memory provides predictable bandwidth, while the Arc G3's performance depends entirely on the host system's memory configuration.

The compute resources differ in count and type. The Arc G3 has 1,280 shading units, 40 texture mapping units, 20 raster output units, and 10 ray tracing cores. The RTX A400 has 768 shading units, 24 texture mapping units, 16 raster output units, 6 ray tracing cores, and 24 tensor cores. The Arc G3 has no listed tensor cores, while the RTX A400 includes them, which is significant for AI workloads. The Arc G3 has substantially more shading units, TMUs, and ROPs, but the RTX A400's tensor cores provide dedicated hardware for certain compute tasks.

Where Each One Wins

The RTX A400's recorded benchmarks show clear strengths in specific areas. Its Geekbench OpenCL score of 22,844 and Vulkan score of 22,237 indicate strong general compute and graphics API performance. These are the only recorded data points, so any analysis of the RTX A400's strengths must center on these results. The Passmark DirectX 9 score of 87 is its best legacy DirectX result, while its DirectX 12 score of 27 is the lowest of its DirectX scores, suggesting older API workloads may perform relatively better.

The Arc G3's architectural specifications suggest potential advantages in raw compute throughput. Its FP32 performance is listed at 6.144 TFLOPS, and its FP16 performance is 12.29 TFLOPS with a 2:1 ratio. The RTX A400's FP32 is 2.706 TFLOPS, and its FP16 is also 2.706 TFLOPS with a 1:1 ratio. The Arc G3's FP32 throughput is more than double the RTX A400's, and its FP16 throughput is over four times higher. These figures indicate the Arc G3 has significantly higher theoretical compute capacity for floating-point workloads.

The pixel and texture rates follow a similar pattern. The Arc G3 has a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. The RTX A400 has a pixel rate of 28.19 GPixel/s and a texture rate of 42.29 GTexel/s. The Arc G3 leads in both metrics, with a 70% advantage in pixel rate and a 127% advantage in texture rate. These differences suggest the Arc G3 is better equipped for fill-rate-intensive workloads.

Power consumption favors the Arc G3, which has a TDP of 25 W versus the RTX A400's 50 W. The Arc G3 is an integrated graphics processor with no power connectors and no suggested PSU, while the RTX A400 is a single-slot card with no power connectors but a suggested PSU of 250 W. The Arc G3's lower power draw combined with its higher theoretical throughput indicates a more efficient design on paper.

The Verdict

The data presents an incomplete comparison, as the Intel Arc G3 has no recorded benchmarks while the NVIDIA RTX A400 has a full set of nine test scores. The RTX A400's performance is well characterized: it sits at the 35th percentile with an average score of 6,078, and its nearest rivals are all within one percent of its average score, indicating it is a mid-to-low-tier performer in the database.

The Arc G3's percentile rank of 50 is higher than the RTX A400's 35, but without measured scores, this rank cannot be validated against actual performance data. The architectural specifications, however, tell a clear story. The Arc G3 offers more than double the FP32 throughput, more than quadruple the FP16 throughput, higher pixel and texture rates, more shading units, more TMUs, more ROPs, and more RT cores. It also uses a smaller process node (3 nm versus 8 nm) and consumes half the power (25 W versus 50 W).

The RTX A400 counters with dedicated GDDR6 memory, tensor cores, a much higher base clock, and a well-established set of benchmark results. Its memory bandwidth of 96.00 GB/s is fixed and predictable, whereas the Arc G3's performance depends on system memory. The RTX A400 also has a known physical form factor (single-slot, 163 mm length) and display outputs (4x mini-DisplayPort 1.4a), making it suitable for workstation deployment.

From the recorded data alone, the RTX A400 is the only GPU with proven performance numbers. From the architectural specifications, the Arc G3 has a theoretical compute advantage that is substantial. The choice depends on whether the user trusts the Arc G3's unverified specifications or the RTX A400's measured results. For workloads requiring dedicated memory and tensor core acceleration, the RTX A400 has clear advantages. For raw floating-point throughput and power efficiency, the Arc G3's specifications indicate superiority, but the absence of benchmark data leaves this unconfirmed.
