The Verdict

The data is unambiguous: the AMD Radeon RX 7900 GRE is the dominant performer in every recorded benchmark. With wins in both head-to-head tests, it holds a 100% win rate against the Intel Arc A370M. The RX 7900 GRE delivers a 492.3% advantage in OpenCL and a 248.2% advantage in Vulkan. For any desktop workload demanding high frame rates, compute throughput, or large texture memory, the RX 7900 GRE is the clear choice.

The Intel Arc A370M, however, serves a completely different purpose. Its 35 W TDP and IGP form factor make it suitable for thin and light laptops or portable devices where battery life and thermal constraints outweigh raw performance. It has no launch MSRP and is already end-of-life, so it is not a forward-looking investment. The RX 7900 GRE is still in active production.

Users building a desktop gaming rig or a workstation with heavy GPU compute should select the RX 7900 GRE. Users who need an integrated-class GPU for a compact mobile device, and who accept a large performance gap, can consider the Arc A370M. The benchmark data does not support any scenario where the Arc A370M wins on performance.

Head-to-Head Benchmarks

The two recorded head-to-head tests show a massive and consistent performance gap. In Geekbench OpenCL, the RX 7900 GRE scores 175758, while the Arc A370M scores 29676. This translates to a delta of 492.3%, meaning the AMD part is nearly six times faster in this compute workload. OpenCL is often used for general-purpose GPU computing, so this result indicates the RX 7900 GRE is in a different performance class entirely for tasks like rendering, physics simulation, or data processing.

In Geekbench Vulkan, the gap narrows slightly but remains overwhelming. The RX 7900 GRE scores 99850, and the Arc A370M scores 28673, a delta of 248.2%. Vulkan is a low-level graphics API used in modern games, so this result directly impacts gaming performance. The RX 7900 GRE is roughly 2.5 times faster in Vulkan, which means higher frame rates and more headroom for demanding titles at high settings.

Beyond these two tests, the broader benchmark database reinforces the same story. The RX 7900 GRE's average score of 32456 is 11.2% higher than the Arc A370M's 29175. The RX 7900 GRE also has a richer benchmark profile, with scores in 3DMark Steel Nomad DX12 (4814), PassMark DirectX 10 (139), DirectX 11 (300), DirectX 12 (107), DirectX 9 (310), G2D (1180), G3D (27089), and GPU Compute (15016). The Arc A370M only has recorded scores in Geekbench OpenCL and Vulkan, limiting direct comparisons but confirming that it trails in every measured discipline.

Specification Differences

The RX 7900 GRE and Arc A370M differ in nearly every core specification. The RX 7900 GRE has 5120 shading units, 320 texture mapping units, and 160 render output units. The Arc A370M has 1024 shading units, 64 TMUs, and 32 ROPs. The AMD part also has 80 ray tracing cores, while the Intel part has 8.

Memory is another major differentiator. The RX 7900 GRE offers 16 GB of GDDR6 on a 256-bit bus with 576.0 GB/s bandwidth. The Arc A370M offers 4 GB of GDDR6 on a 64-bit bus with 112.0 GB/s bandwidth. The RX 7900 GRE's memory clock is 2250 MHz (18 Gbps effective), while the Arc A370M runs at 1750 MHz (14 Gbps effective).

The RX 7900 GRE has a base clock of 1287 MHz, a boost clock of 2245 MHz, and a game clock of 1880 MHz. The Arc A370M has a base clock of 1550 MHz and a boost clock of 2050 MHz, with no game clock listed. Despite lower clocks, the RX 7900 GRE achieves far higher throughput due to its larger execution resources.

Physical and power specifications also diverge sharply. 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 suggested PSU. The Arc A370M is an IGP, meaning it is integrated into a host device, with no dimensions, connectors, or PSU recommendation. The RX 7900 GRE has a TDP of 260 W; the Arc A370M has a TDP of 35 W.

The bus interface differs as well: the RX 7900 GRE uses PCIe 4.0 x16, while the Arc A370M uses PCIe 4.0 x8. Display outputs are also different: the RX 7900 GRE has 1x HDMI 2.1a, 2x DisplayPort 2.1, and 1x USB Type-C, while the Arc A370M's outputs are portable-device dependent.

Architecture Differences

The RX 7900 GRE is built on the RDNA 3.0 architecture, codenamed Plum Bonito, and belongs to the Navi III (RX 7000) generation. It uses the Navi 31 chip. The Arc A370M uses the Xe-HPG architecture, generation Alchemist (Arc 3 Mobile), with the DG2-128 chip. These are fundamentally different GPU designs: RDNA 3.0 is AMD's gaming-first architecture with a focus on compute per watt, while Xe-HPG is Intel's dedicated GPU architecture designed for both gaming and compute in mobile form factors.

The manufacturing processes differ: the RX 7900 GRE uses a 5 nm node at TSMC, while the Arc A370M uses a 6 nm node at TSMC. The transistor counts reflect the size difference. The RX 7900 GRE packs 57,700 million transistors on a 529 mm² die, yielding a density of 109.1M transistors per mm². The Arc A370M has 7,200 million transistors on a 157 mm² die, with a density of 45.9M per mm². The RX 7900 GRE is a much larger and denser chip, explaining its substantial performance lead.

The RX 7900 GRE's FP32 throughput is 45.98 TFLOPS, and its FP16 throughput is 91.96 TFLOPS (2:1 ratio). The Arc A370M's FP32 is 4.198 TFLOPS, and FP16 is 8.397 TFLOPS (2:1 ratio). This means the RX 7900 GRE has roughly 11 times the raw FP32 compute. Pixel and texture rates follow the same pattern: the RX 7900 GRE hits 359.2 GPixel/s and 718.4 GTexel/s, while the Arc A370M manages 65.60 GPixel/s and 131.2 GTexel/s.

Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API feature levels are identical. The RX 7900 GRE was released on 2023-07-26, while the Arc A370M was released on 2022-03-29. The RX 7900 GRE has a predecessor (Navi II) and successor (Navi IV), while the Arc A370M has neither listed. The RX 7900 GRE is active in production; the Arc A370M is end-of-life.

Where Each One Wins

The RX 7900 GRE wins every recorded benchmark, so its advantages are absolute in the available data. It wins in OpenCL compute by 492.3%, making it the clear choice for any workload that leverages GPGPU compute, such as video encoding, scientific simulation, or machine learning inference. It wins in Vulkan by 248.2%, which directly benefits gaming and real-time 3D rendering. Its 16 GB memory capacity and 576.0 GB/s bandwidth also make it suited for large textures, high-resolution rendering, and data-heavy workloads.

The Arc A370M's wins are not in the benchmark scores but in its form factor and power profile. Its 35 W TDP is dramatically lower than the RX 7900 GRE's 260 W, making it suitable for devices where thermal and power budgets are tight, such as ultra-portable laptops. Its IGP classification means it requires no external power connectors, simplifying integration. It has a smaller die (157 mm² versus 529 mm²) and fewer transistors (7,200 million versus 57,700 million), which aligns with a low-power, space-constrained design.

For desktop users with a dedicated PSU and chassis space, the RX 7900 GRE is the only rational choice based on performance. For mobile users who need a built-in GPU with modest performance and minimal power draw, the Arc A370M has a place, but the data shows it is not competitive with the RX 7900 GRE in any performance metric. The RX 7900 GRE also has a longer production life ahead, as it remains active while the Arc A370M is end-of-life.
