AMD Radeon RX 7900 GRE vs Intel Arc G3 Comparison

Where Each One Wins

The AMD Radeon RX 7900 GRE is the clear performance leader across every benchmark category where data exists. Its recorded benchmark suite includes ten distinct tests covering DirectX 9 through DirectX 12, OpenCL, Vulkan, 2D graphics, and general GPU compute. The Intel Arc G3 has no recorded benchmark scores in the database, meaning it cannot claim a single measured win in any test category. The data shows a complete monopoly for the AMD part in terms of measurable performance outcomes.

The RX 7900 GRE posts its strongest absolute scores in compute-oriented workloads. Its Geekbench OpenCL result of 175758 and Vulkan score of 99850 indicate substantial raw throughput capabilities. The Passmark G3D score of 27089 confirms strong general 3D rendering performance, while the Passmark GPU Compute score of 15016 demonstrates dedicated compute headroom beyond graphics workloads. The Intel Arc G3, with an average benchmark score of zero and no benchmark entries, delivers no comparable measured results.

The AMD card also shows strong legacy API performance. Passmark DirectX 9 score of 310 and DirectX 11 score of 300 indicate the architecture handles older rendering paths effectively. DirectX 10 and DirectX 12 scores of 139 and 107 respectively round out the API coverage. The 3DMark Steel Nomad DX12 score of 4814 provides a modern, DirectX 12-focused measurement that further separates the two products. Every recorded score favors the RX 7900 GRE, with the Arc G3 lacking any countervailing data.

Architecture Differences

The two processors come from fundamentally different design philosophies. The AMD Radeon RX 7900 GRE uses the Navi 31 chip built on RDNA 3.0 architecture with the Plum Bonito codename, manufactured on a 5 nm process at TSMC. The Intel Arc G3 uses the Panther Lake chip with Xe3-LPG architecture, produced on a 3 nm process at Intel's own foundry. The node difference is notable: Intel's 3 nm process is denser on paper, but the AMD chip integrates 57,700 million transistors across a 529 mm² die, yielding a transistor density of 109.1M per mm². Intel does not disclose transistor count, die size, or density for the Arc G3.

The compute resource gap is massive. The RX 7900 GRE contains 5120 shading units, 320 texture mapping units, 160 ROPs, and 80 ray tracing cores. The Arc G3 contains only 1280 shading units, 40 TMUs, 20 ROPs, and 10 ray tracing cores. That is a 4:1 ratio in shading units, 8:1 in TMUs, 8:1 in ROPs, and 8:1 in ray tracing cores. These ratios directly explain the performance deltas in every benchmark category.

Clock behavior also differs sharply. The RX 7900 GRE runs a 1287 MHz base clock, 1880 MHz game clock, and 2245 MHz boost clock. The Arc G3 runs a 300 MHz base clock and 2400 MHz boost clock, but has no game clock listed. The AMD card's memory clock is 2250 MHz with 18 Gbps effective data rate, while the Arc G3 relies on system shared memory with no dedicated memory clock. The AMD part uses 16 GB of GDDR6 on a 256-bit bus delivering 576.0 GB/s bandwidth. The Arc G3's memory size, type, bus width, and bandwidth are all listed as system shared or system dependent.

Pixel and texture throughput further illustrate the gap. The RX 7900 GRE achieves 359.2 GPixel/s pixel rate and 718.4 GTexel/s texture rate. The Arc G3 achieves 48.00 GPixel/s and 96.00 GTexel/s. FP32 compute is 45.98 TFLOPS for AMD versus 6.144 TFLOPS for Intel, a factor of roughly 7.5. FP16 rates are 91.96 TFLOPS for AMD versus 12.29 TFLOPS for Intel, both at a 2:1 ratio.

Power and physical design differ completely. The RX 7900 GRE carries a 260 W TDP, dual-slot cooler, two 8-pin power connectors, and a 600 W suggested PSU. It measures 276 mm in length, 110 mm in height, and 51 mm in width. The Arc G3 is an integrated graphics processor with a 25 W TDP, IGP slot width, no power connectors, no suggested PSU, and no listed dimensions. The AMD card uses a PCIe 4.0 x16 bus interface, while the Arc G3 uses IGP integration. Display outputs also differ: the RX 7900 GRE provides 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the Arc G3's outputs are portable device dependent.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The AMD card is from the Radeon RX 7000 series, part of the Navi III generation, succeeding Navi II and preceding Navi IV. The Intel part belongs to Arc Graphics-M (Panther Lake) generation. Neither has tensor cores listed.

The Verdict

The data supports only one conclusion for performance-oriented use: the AMD Radeon RX 7900 GRE dominates every measurable metric. It holds a 77th percentile ranking among all GPUs in the database, while the Intel Arc G3 sits at the 50th percentile. Its average benchmark score of 32456 dwarfs the Arc G3's zero recorded score. The RX 7900 GRE's nearest rivals in the database, the AMD FirePro S10000 at 32388 with a 0.2% delta and the AMD FirePro S9300 X2 at 32540 with a -0.3% delta, show that the card sits in a competitive cluster of high-end AMD workstation parts. The Arc G3 has no nearest rivals listed, as it has no benchmark data to compare.

The Arc G3 is an integrated processor with a 25 W TDP and system shared memory. It is designed for portable devices, as its display outputs are portable device dependent. Its 50th percentile ranking reflects a mid-range position among all GPUs, but without benchmark scores, that ranking cannot be validated against actual performance data. The RX 7900 GRE is a discrete, dual-slot add-in card with dedicated GDDR6 memory and a 260 W TDP. It launched on 2023-07-26 with a launch MSRP of 549 USD. The Arc G3 has no launch MSRP listed.

For workloads requiring high throughput, the RX 7900 GRE is the only choice with supporting evidence. Its 45.98 TFLOPS FP32 compute, 576.0 GB/s memory bandwidth, and 16 GB VRAM provide the resources needed for demanding rendering and compute tasks. The Arc G3's 6.144 TFLOPS FP32 and system dependent bandwidth place it in a different performance class entirely. The production status of both is active, but the Arc G3's release date of 2026-05-31 is nearly three years after the RX 7900 GRE's release, suggesting a different product category rather than a direct competitor.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark comparisons between the RX 7900 GRE and the Arc G3. The head-to-head benchmark array is empty, and the win counts for both items are zero. The comparison must therefore rely on the individual benchmark suites recorded for each product.

For the RX 7900 GRE, the strongest result relative to its own suite is the Geekbench OpenCL score of 175758, which exceeds its Vulkan score of 99850 by a wide margin. The 3DMark Steel Nomad DX12 score of 4814 provides a modern gaming-oriented measurement. Passmark results show a G3D score of 27089, a GPU Compute score of 15016, and a G2D score of 1180. Legacy API scores are lower: DirectX 9 at 310, DirectX 11 at 300, DirectX 10 at 139, and DirectX 12 at 107.

The Arc G3 has no scores in any of these categories. Its average benchmark score is recorded as zero, and its benchmark list is empty. The nearest rivals for the RX 7900 GRE provide context for its positioning: the AMD FirePro S10000 scores 32388 on average with a 0.2% delta, the AMD FirePro S9300 X2 scores 32540 with a -0.3% delta, the AMD Radeon RX 590 GME scores 32601 with a -0.4% delta, and the AMD Radeon Pro 570X scores 32176 with a 0.9% delta. The RX 7900 GRE's average of 32456 places it within a tight cluster of these four rivals, all within roughly one percentage point of each other.

This clustering indicates that the RX 7900 GRE's performance is well understood relative to other AMD parts in the database. The Arc G3, by contrast, has no such positioning data. Its 50th percentile ranking suggests it is not an outlier in either direction, but the absence of measured scores means no quantitative comparison with the RX 7900 GRE is possible. The performance gap implied by the architectural differences, 5120 versus 1280 shading units and 45.98 versus 6.144 TFLOPS FP32, is consistent with the complete absence of Arc G3 benchmark entries.
