Architecture Differences

The AMD Radeon RX 7900 GRE and Intel Arc A310E represent fundamentally different design philosophies. The RX 7900 GRE uses the Navi 31 chip with RDNA 3.0 architecture under the codename Plum Bonito, part of the Navi III generation. The Arc A310E uses the DG2-128 chip with Xe-HPG architecture, belonging to the Alchemist generation. Both cards are manufactured by TSMC, but on different nodes: the AMD card uses 5 nm, while the Intel card uses 6 nm.

The physical scale of these chips differs substantially. The Navi 31 die measures 529 mm² and contains 57,700 million transistors, yielding a transistor density of 109.1M / mm². The DG2-128 die is much smaller at 157 mm² with 7,200 million transistors, resulting in a density of 45.9M / mm². This size disparity reflects the different market positions and performance targets of the two products.

The compute configurations diverge sharply. The Radeon RX 7900 GRE packs 5120 shading units, 320 texture mapping units, 160 ROPs, and 80 ray tracing cores. The Arc A310E offers 768 shading units, 32 TMUs, 16 ROPs, and 6 ray tracing cores. These numbers indicate a roughly 6.7x advantage in shading units for the AMD card, which translates directly into its much higher theoretical throughput: 45.98 TFLOPS FP32 versus 3.072 TFLOPS FP32 for the Intel card.

Memory architecture also differs fundamentally. The RX 7900 GRE uses a 256-bit memory bus with 16 GB of GDDR6, while the Arc A310E uses a 64-bit bus with 4 GB of GDDR6. The bandwidth gap is enormous: 576.0 GB/s versus 124.0 GB/s. The memory clock rates also differ, with the AMD card running at 2250 MHz (18 Gbps effective) and the Intel card at 1937 MHz (15.5 Gbps effective).

The physical and electrical characteristics show the different design goals. The RX 7900 GRE is a dual-slot card measuring 276 mm in length, 110 mm in height, and 51 mm in width, requiring two 8-pin power connectors and a 600 W PSU. The Arc A310E is a single-slot card measuring 168 mm by 69 mm by 20 mm, requiring no power connectors and only a 250 W PSU. The AMD card has a TDP of 260 W, while the Intel card draws just 75 W.

Both cards support the same API feature set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Display outputs differ, with the RX 7900 GRE offering 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the Arc A310E offers 4x mini-DisplayPort 2.0. The bus interfaces also differ: the AMD card uses PCIe 4.0 x16, while the Intel card uses PCIe 4.0 x8.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark results between the Radeon RX 7900 GRE and the Arc A310E. The Arc A310E has no recorded benchmark scores at all, with an empty benchmark array and an average score of 0. This makes a direct numerical comparison impossible.

The Radeon RX 7900 GRE, however, has a substantial set of recorded benchmarks. In 3DMark Steel Nomad DX12, it scores 4814. In Geekbench OpenCL, it scores 175758, and in Geekbench Vulkan, it scores 99850. The Passmark suite shows mixed results: DirectX 10 scores 139, DirectX 11 scores 300, DirectX 12 scores 107, and DirectX 9 scores 310. The Passmark G2D score is 1180, the G3D score is 27089, and the GPU compute score is 15016.

The average benchmark score for the RX 7900 GRE is 32456. Its nearest rivals in the database provide context for this figure. The AMD FirePro S10000 has an average score of 32388, a delta of 0.2%. The AMD FirePro S9300 X2 scores 32540, a delta of -0.3%. The AMD Radeon RX 590 GME scores 32601, a delta of -0.4%. The AMD Radeon Pro 570X scores 32176, a delta of 0.9%. These deltas show the RX 7900 GRE sits within a narrow band of comparable GPUs, all within roughly one percentage point of each other.

The Arc A310E, lacking any benchmark data, cannot be placed relative to these scores. Its 50th percentile ranking derives from its hardware specifications rather than measured performance. The RX 7900 GRE, by contrast, ranks in the 77th percentile of all GPUs based on its recorded scores.

The Verdict

The data presents a clear performance hierarchy. The Radeon RX 7900 GRE delivers 45.98 TFLOPS FP32, 16 GB of GDDR6 memory, and 576.0 GB/s of bandwidth, with an average benchmark score of 32456 and a 77th percentile ranking. The Arc A310E delivers 3.072 TFLOPS FP32, 4 GB of GDDR6, and 124.0 GB/s of bandwidth, with no recorded benchmark scores and a 50th percentile ranking.

The RX 7900 GRE is the choice for workloads demanding maximum compute throughput, large memory capacity, and high memory bandwidth. Its rendering rates reflect this: 359.2 GPixel/s pixel rate and 718.4 GTexel/s texture rate, versus 32.00 GPixel/s and 64.00 GTexel/s for the Arc A310E. The AMD card also supports a wider display output configuration, including HDMI 2.1a and USB Type-C.

The Arc A310E serves a different purpose. Its 75 W TDP, single-slot design, and lack of power connectors make it suitable for compact or low-power systems. The 250 W suggested PSU requirement, compared to 600 W for the RX 7900 GRE, indicates a much lower system power envelope. Its 168 mm length and 20 mm width allow installation in spaces that cannot accommodate the 276 mm long, 51 mm wide RX 7900 GRE.

The production statuses reinforce this distinction. The RX 7900 GRE is Active, while the Arc A310E is End-of-life. The AMD card launched on 2023-07-26, while the Intel card launched on 2024-03-31. The RX 7900 GRE has a successor in Navi IV, and the Arc A310E has a successor in Battlemage.

For users prioritizing raw performance, memory capacity, and measured benchmark results, the RX 7900 GRE is the only option with data supporting it. For users prioritizing low power draw, compact physical footprint, and minimal system requirements, the Arc A310E offers those attributes, though without benchmark verification of its performance.

Specification Differences

The Arc A310E has a base and boost clock of 2000 MHz with no game clock listed. Memory clocks are 2250 MHz (18 Gbps effective) for the AMD card and 1937 MHz (15.5 Gbps effective) for the Intel card.

Memory configurations differ in size, bus width, and bandwidth: 16 GB versus 4 GB, 256-bit versus 64-bit, and 576.0 GB/s versus 124.0 GB/s. The compute units differ: 5120 shading units versus 768, 320 TMUs versus 32, 160 ROPs versus 16, and 80 RT cores versus 6. The throughput figures are 45.98 TFLOPS FP32 versus 3.072 TFLOPS FP32, and 91.96 TFLOPS FP16 versus 6.144 TFLOPS FP16.

Power and physical specifications diverge completely. The TDP is 260 W versus 75 W. The RX 7900 GRE is dual-slot with 2x 8-pin power connectors and a 600 W suggested PSU; the Arc A310E is single-slot with no power connectors and a 250 W suggested PSU. Dimensions are 276 mm x 110 mm x 51 mm versus 168 mm x 69 mm x 20 mm.

The bus interfaces differ: PCIe 4.0 x16 versus PCIe 4.0 x8. Display outputs are 1x HDMI 2.1a, 2x DisplayPort 2.1, 1x USB Type-C versus 4x mini-DisplayPort 2.0.
