AMD Radeon RX 7900M vs Intel Arc G3 Comparison

Head-to-Head Benchmarks

The recorded data shows a stark contrast between these two mobile graphics solutions. The AMD Radeon RX 7900M delivers an average benchmark score of 97,487 across its tested workloads, placing it in the 94th percentile of all GPUs in the database. The Intel Arc G3, by contrast, has no recorded benchmark scores in the database at this time, leaving its average benchmark score at 0 and its percentile standing at 50. This means there is no direct head-to-head comparison data available, so the analysis relies on the AMD part's standalone results and its nearest rival comparisons.

The AMD Radeon RX 7900M posts a 3DMark Steel Nomad DX12 score of 4,201. In Geekbench compute tests, it reaches 129,499 in OpenCL and 158,760 in Vulkan. These are the only three recorded benchmark results for the AMD part. The Intel Arc G3 has zero entries in the benchmark section of the database, so no score, no percentile shift, and no rival comparisons can be cited. The data indicates that the RX 7900M is a fully characterized product, while the Arc G3 remains unmeasured in this database.

Looking at the RX 7900M's nearest rivals, the average score of 97,487 puts it 0.4% ahead of the AMD Radeon Pro VII, which averages 97,131. It trails the NVIDIA Quadro RTX 6000 by 4.3%, as that card averages 101,872. The RX 7900M sits 5.4% above the AMD Radeon Instinct MI60, which averages 92,466, and 6.3% above the NVIDIA RTX A4500, which averages 91,671. These deltas show the RX 7900M competing in professional and workstation-class territory, despite being a mobile part. The Intel Arc G3 has no nearest rivals listed, so its relative standing cannot be established from the database.

Architecture Differences

The architectural gap between these two parts is substantial. The AMD Radeon RX 7900M uses the Navi 31 chip built on RDNA 3.0 architecture, with the codename Plum Bonito. It belongs to the Navi Mobile generation within the RX 7000M family. The process node is 5 nm, fabricated by TSMC. The Intel Arc G3 uses the Panther Lake chip built on Xe3-LPG architecture, with no codename listed. It belongs to the Arc Graphics-M (Panther Lake) generation. The process node is 3 nm, fabricated by Intel.

Transistor counts differ dramatically. The RX 7900M contains 57,700 million transistors on a 529 mm² die, yielding a transistor density of 109.1 million per square millimeter. The Arc G3 lists transistor count, die size, and transistor density as unknown in the database. This means the data cannot confirm the Intel part's physical scale, only its manufacturing process.

Memory architecture separates the two entirely. The RX 7900M uses 16 GB of GDDR6 memory on a 256-bit bus, delivering 576.0 GB/s of bandwidth. Its memory clock runs at 2250 MHz, translating to 18 Gbps effective. The Arc G3 uses system shared memory, with system shared type, bus width, and bandwidth. Its memory clock is listed as system shared, and bandwidth is system dependent. This indicates the Intel part relies on the host system's memory rather than dedicated VRAM.

Compute resources show a wide gap. The RX 7900M has 4,608 shading units, 288 texture mapping units, 192 ROPs, and 72 ray tracing cores. The Arc G3 has 1,280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. The AMD part's pixel rate is 401.3 GPixel/s versus 48.00 GPixel/s for the Intel part. Texture rate is 601.9 GTexel/s versus 96.00 GTexel/s. FP32 compute is 38.52 TFLOPS versus 6.144 TFLOPS. FP16 compute reaches 77.05 TFLOPS (2:1) on the AMD part versus 12.29 TFLOPS (2:1) on the Intel part.

Clock behavior also differs. The RX 7900M has a base clock of 1825 MHz and a boost clock of 2090 MHz. The Arc G3 has a base clock of 300 MHz and a boost clock of 2400 MHz. The Intel part boosts higher but starts far lower. Power targets are not comparable: the RX 7900M carries a TDP of 180 W, while the Arc G3 sits at 25 W. Both are listed as IGP slot width with no power connectors, and both have portable device dependent display outputs. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The RX 7900M connects via PCIe 4.0 x16, while the Arc G3 uses an IGP bus interface.

Where Each One Wins

The AMD Radeon RX 7900M wins in every category where the database has recorded data. Its 94th percentile standing among all GPUs confirms high placement in the overall performance distribution. The 3DMark Steel Nomad DX12 score of 4,201 indicates strong DirectX 12 rasterization performance. The Geekbench OpenCL score of 129,499 and Vulkan score of 158,760 show solid compute and cross-API capabilities. The RX 7900M's 16 GB of dedicated GDDR6 memory with 576.0 GB/s bandwidth gives it a clear advantage for workloads that need large, fast local memory pools.

The Intel Arc G3 has no recorded wins in the database. Its 50th percentile standing is the default midpoint, not a measured result. Its strengths are structural rather than benchmarked. The 3 nm process node from Intel suggests a modern manufacturing technology. The 25 W TDP indicates low power consumption, which is relevant for thin-and-light portable devices. The system shared memory design means the GPU does not need its own VRAM allocation, which can simplify system design. The higher boost clock of 2400 MHz shows headroom for burst performance, though the base clock of 300 MHz is very low.

The RX 7900M's pixel rate of 401.3 GPixel/s and texture rate of 601.9 GTexel/s indicate strong fill-rate performance for high-resolution rendering. The Arc G3's 48.00 GPixel/s and 96.00 GTexel/s are far lower. The FP32 compute gap (38.52 TFLOPS versus 6.144 TFLOPS) is a factor of more than six, which matters for compute-heavy tasks. The ray tracing core count difference (72 versus 10) suggests the AMD part has more hardware dedicated to ray traversal.

For gaming and workstation use, the RX 7900M delivers measured performance that places it alongside professional cards like the Quadro RTX 6000 and Radeon Pro VII. For ultra-portable systems where battery life and thermals dominate, the Arc G3's 25 W TDP and shared memory architecture fit a different design goal. The data does not support the Arc G3 competing on raw performance, but it does show a fundamentally different product category.

The Verdict

The database clearly separates these two GPUs. The AMD Radeon RX 7900M is a fully benchmarked, high-performance mobile part with an average score of 97,487, a 94th percentile standing, and competitive deltas against workstation-class rivals. Its 16 GB of GDDR6 memory, 576.0 GB/s bandwidth, and 38.52 TFLOPS of FP32 compute place it in a performance tier that the Intel Arc G3 does not approach based on recorded data. The RX 7900M is the choice for users who need measured, verified GPU performance in a laptop, particularly for gaming, 3D rendering, or compute workloads that stress dedicated VRAM and high fill rates.

The Intel Arc G3, with no benchmark scores in the database and a 50th percentile default standing, cannot be recommended on performance evidence. Its 3 nm Intel process and 25 W TDP indicate a low-power design intended for efficiency, not throughput. The system shared memory architecture and IGP bus interface confirm its role as an integrated-class solution. Users who prioritize battery life, thin chassis design, and minimal power draw may find the Arc G3 suitable, but the database provides no measured performance data to validate its capabilities.

The verdict from the data is straightforward. The RX 7900M delivers verified, quantifiable performance with a clear competitive position against known rivals. The Arc G3 remains an unmeasured quantity in the database, with structural specifications that suggest a different market segment. For any workload where GPU performance matters, the RX 7900M is the only part with recorded evidence of its capabilities. For ultra-low-power portable systems, the Arc G3's specifications indicate a lighter footprint, but no benchmark results exist to confirm its real-world behavior.
