Architecture Differences

The AMD Radeon RX 7900M is built on the RDNA 3.0 architecture with the Navi 31 chip, codenamed Plum Bonito, and belongs to the Navi Mobile generation (RX 7000M series). It uses a 5 nm process from TSMC, contains 57,700 million transistors, and has a die size of 529 mm², giving a transistor density of 109.1M per mm². The Intel Arc G3 Extreme uses the Xe3-LPG architecture with the Panther Lake chip, belongs to the Arc Graphics-M generation, and uses a 3 nm process from Intel. Its transistor count and die size are unknown in the database.

The compute resources differ by a wide margin. The RX 7900M has 4608 shading units, 288 texture mapping units, 192 ROPs, and 72 ray tracing cores. The Arc G3 Extreme has 1536 shading units, 48 TMUs, 24 ROPs, and 12 ray tracing cores. Both GPUs report the same API support: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Clock behavior also differs substantially. The RX 7900M runs at a base clock of 1825 MHz and boosts to 2090 MHz, with memory clocked at 2250 MHz (18 Gbps effective). The Arc G3 Extreme has a base clock of only 300 MHz but a higher boost clock of 2500 MHz. Its memory clock is listed as system shared.

The RX 7900M uses a PCIe 4.0 x16 bus interface, while the Arc G3 Extreme uses an integrated graphics processor (IGP) bus interface. Both are classified as IGP slot width with portable device dependent display outputs. The RX 7900M was released on 2023-10-18, and the Arc G3 Extreme on 2026-05-31. The RX 7900M has a predecessor listed as Polaris Mobile, while the Arc G3 Extreme has no predecessor recorded.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the RX 7900M and the Arc G3 Extreme, and neither GPU records a win count in such matchups. However, the available individual benchmark data provides a clear comparison.

The RX 7900M records a 3DMark Steel Nomad DX12 score of 4201. No equivalent score exists for the Arc G3 Extreme. In Geekbench OpenCL, the RX 7900M scores 129499, and in Geekbench Vulkan it scores 158760. The Arc G3 Extreme has no recorded scores for any test.

The average benchmark score for the RX 7900M is 97487, placing it in the 94th percentile. Its nearest rival, the AMD Radeon Pro VII, averages 97131, which is 0.4% lower. The NVIDIA Quadro RTX 6000 averages 101872, 4.3% higher. The AMD Radeon Instinct MI60 averages 92466, 5.4% lower, and the NVIDIA RTX A4500 averages 91671, 6.3% lower. These deltas indicate that the RX 7900M sits within a tight cluster of workstation-oriented GPUs, slightly below the Quadro RTX 6000 but above the Radeon Pro VII, Instinct MI60, and RTX A4500.

The Arc G3 Extreme has an average benchmark score of 0 and no nearest rivals recorded in the database. Its 50th percentile placement indicates it sits at the median of all GPUs, but without benchmark scores the database cannot quantify its performance relative to any specific competitor.

The pixel and texture rates reinforce the gap. The RX 7900M delivers 401.3 GPixel/s and 601.9 GTexel/s. The Arc G3 Extreme delivers 60.00 GPixel/s and 120.0 GTexel/s. These figures come directly from the recorded specifications and show a 6.7x difference in pixel throughput and a 5.0x difference in texture throughput, though the database does not label these as benchmark results.

The Verdict

The recorded data indicates that the AMD Radeon RX 7900M is the higher-performing GPU by every measurable metric. Its 94th percentile placement, average benchmark score of 97487, and three individual scores across DX12, OpenCL, and Vulkan tests confirm that it delivers substantial compute and graphics throughput. The Arc G3 Extreme, by contrast, has no recorded benchmark scores and sits at the 50th percentile, which the database defines as the median but cannot support with any measured results.

For users who prioritize raw performance in GPU-bound workloads, the RX 7900M is the clear choice based on the available data. Its nearest rivals, all workstation-class GPUs from AMD and NVIDIA, fall within a 6.3% range of its average score, which indicates that it belongs in that performance tier. The Arc G3 Extreme offers no comparable benchmark evidence, so its performance cannot be validated against the same standard.

The RX 7900M also carries a 180 W TDP versus 80 W for the Arc G3 Extreme. That power difference aligns with the performance gap, but the database does not provide efficiency metrics, so any efficiency comparison would be speculative. The Arc G3 Extreme uses system shared memory, which ties its memory performance to the host system, while the RX 7900M has dedicated 16 GB GDDR6 with 576.0 GB/s bandwidth. For applications that depend on dedicated memory bandwidth, the RX 7900M has a structural advantage.

The choice depends on the context. For a discrete GPU with measured performance and a known position among rivals, the RX 7900M is the only option with supporting data. For an integrated solution with lower power draw and a 3 nm process, the Arc G3 Extreme offers a different tradeoff, but its performance remains unquantified in the database.

Fields that are identical include slot width (IGP for both), power connectors (none for both), display outputs (portable device dependent for both), and API support (DirectX 12 Ultimate 12_2, OpenGL 4.6, Vulkan 1.4 for both). Neither GPU has a recorded launch MSRP, length, height, or width.

Where Each One Wins

The RX 7900M wins in every category where the database has recorded data. Its FP32 throughput of 38.52 TFLOPS is five times the 7.680 TFLOPS of the Arc G3 Extreme. Its FP16 throughput of 77.05 TFLOPS is likewise five times the 15.36 TFLOPS. Pixel rate and texture rate show similar ratios, and the RX 7900M has three times the shading units, six times the TMUs, eight times the ROPs, and six times the ray tracing cores.

The RX 7900M also wins on memory. Its dedicated 16 GB GDDR6 with 576.0 GB/s bandwidth stands against the Arc G3 Extreme's system shared memory with system dependent bandwidth. For workloads that stress memory bandwidth, such as high-resolution rendering or large dataset processing, the RX 7900M has a structural advantage that the database records directly.

The Arc G3 Extreme wins on power consumption. Its 80 W TDP is less than half the 180 W TDP of the RX 7900M. It also uses a newer 3 nm process from Intel, while the RX 7900M uses a 5 nm process from TSMC. The Arc G3 Extreme has a higher boost clock of 2500 MHz versus 2090 MHz for the RX 7900M, though its base clock is far lower at 300 MHz versus 1825 MHz.

For integrated graphics use cases where the GPU shares system memory and the host CPU provides the memory controller, the Arc G3 Extreme fits that model. Its IGP bus interface and system shared memory are consistent with an integrated design. The RX 7900M, with its PCIe 4.0 x16 interface and dedicated memory, fits a discrete mobile graphics model.

The database does not record any benchmark wins for either GPU in head-to-head matchups, and it records no head-to-head benchmark entries at all. The performance split therefore rests entirely on the individual benchmark scores and specification differences. The RX 7900M owns all measured performance categories, while the Arc G3 Extreme owns the lower power envelope and the smaller process node.
