The Arc A570M sits in a tight competitive cluster where the largest gap to any rival is less than one percent.

Architecture Differences

The AMD Radeon 840M and Intel Arc A570M diverge significantly in their underlying architectures. The AMD part uses the RDNA 3.5 architecture, built on a 4 nm process at TSMC, and is part of the Navi III IGP generation for Strix Point Mobile. Its chip is designated Krackan Point. The Intel part uses the Xe-HPG architecture, fabricated on a 6 nm process also at TSMC, and belongs to the Alchemist generation under the Arc 5 Mobile family. Its chip is the DG2-256.

The Intel Arc A570M carries substantial transistor counts and die size data, with 11,500 million transistors on a 269 mm² die, yielding a transistor density of 42.8 million per square millimeter. The AMD Radeon 840M's transistor count and die size are listed as unknown, so no comparison can be made on those physical characteristics.

The compute configurations differ by a wide margin. The AMD Radeon 840M has 256 shading units, 16 texture mapping units, 8 raster output units, and 4 ray tracing cores. The Intel Arc A570M has 2048 shading units, 128 texture mapping units, 64 raster output units, and 16 ray tracing cores. This means the Intel part has eight times the shading units, eight times the texture units, eight times the raster output units, and four times the ray tracing cores compared to the AMD IGP.

Clock speeds also contrast sharply. The AMD Radeon 840M runs at a base clock of 400 MHz and a boost clock of 2900 MHz. The Intel Arc A570M runs at a base clock of 900 MHz and a boost clock of 1300 MHz. The AMD part has a much higher boost ceiling, more than double that of the Intel part, though the Intel part starts from a higher base frequency. The AMD's boost advantage does not overcome the Intel's raw compute advantage, as the pixel rate figures show: the AMD delivers 23.20 GPixel/s while the Intel delivers 83.20 GPixel/s. Texture rates are 46.40 GTexel/s for the AMD versus 166.4 GTexel/s for the Intel.

Memory architecture is a fundamental difference. The AMD Radeon 840M uses system shared memory, with its size, type, bus width, and bandwidth all dependent on the host system. The Intel Arc A570M has dedicated 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. The Intel memory clock is listed at 1750 MHz with 14 Gbps effective data rate. This dedicated memory arrangement gives the Intel part predictable and consistent memory performance, whereas the AMD IGP's performance depends entirely on the host system's memory configuration.

Power consumption is another major divider. The AMD Radeon 840M has a TDP of 15 W, while the Intel Arc A570M has a TDP of 75 W. Both are classified as IGP form factors with portable device dependent display outputs. Both use a PCIe 4.0 x8 bus interface. The AMD part has no power connectors, while the Intel part's power connector information is not listed. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so their API feature sets are identical.

The Verdict

The recorded data indicates a clear performance hierarchy between these two parts. The Intel Arc A570M, with its 88th percentile ranking and a Geekbench OpenCL score of 58,239, sits in a competitive range with desktop GPUs like the AMD Radeon RX 6950 XT and the NVIDIA P102-100. The AMD Radeon 840M has no recorded benchmark scores and sits at the 50th percentile, which suggests it occupies a mid-tier position among all GPUs, but without direct measurements, its actual performance cannot be verified against the Intel part.

The specification data reinforces this gap. The Intel Arc A570M has 2048 shading units versus 256 for the AMD Radeon 840M, a 4.6 TFLOPS advantage in FP32 compute (5.325 TFLOPS versus 1,484.8 GFLOPS), and 8 GB of dedicated GDDR6 memory versus system shared memory. The Intel part also delivers 3.6 times the pixel rate and 3.6 times the texture rate of the AMD part. These are substantial architectural advantages that the AMD's higher boost clock cannot offset.

The AMD Radeon 840M does hold advantages in power efficiency, with a 15 W TDP versus 75 W for the Intel part, and in its more advanced 4 nm process node versus the Intel's 6 nm node. For systems where power draw is the primary constraint and integrated graphics are required, the AMD part is the more conservative choice. For raw graphics throughput and dedicated memory, the Intel Arc A570M is the superior option based on the recorded data.

Specification Differences

The two GPUs differ across nearly every measurable specification. The AMD Radeon 840M uses the RDNA 3.5 architecture on a 4 nm process, while the Intel Arc A570M uses Xe-HPG on a 6 nm process. The Intel part has 11,500 million transistors on a 269 mm² die, while the AMD part's transistor count and die size are unknown.

Compute resources show the largest divergence. The AMD Radeon 840M has 256 shading units, 16 TMUs, 8 ROPs, and 4 RT cores. The Intel Arc A570M has 2048 shading units, 128 TMUs, 64 ROPs, and 16 RT cores.

The AMD part has no power connectors, while the Intel part's connector information is not recorded. Release dates differ, with the AMD part dated 2025-02-28 and the Intel part dated 2023-07-31.

Where Each One Wins

The Intel Arc A570M wins in every measured and spec-derived performance category. Its Geekbench OpenCL score of 58,239 places it at the 88th percentile, within 0.7% of the AMD Radeon PRO V710 and within 0.3% of the AMD Radeon RX 6950 XT. Its 2048 shading units, 128 TMUs, and 64 ROPs provide the compute foundation for this result. The dedicated 8 GB GDDR6 memory with 224.0 GB/s bandwidth ensures that memory throughput does not bottleneck the GPU, which is a critical advantage for texture-heavy workloads and higher resolutions. The 16 RT cores give it four times the ray tracing capability of the AMD part, making it the better choice for applications that use hardware-accelerated ray tracing.

The AMD Radeon 840M wins in power efficiency and clock speed. Its 15 W TDP is one fifth of the Intel part's 75 W TDP, making it suitable for thin-and-light portable devices where thermal and power budgets are tight. Its 2900 MHz boost clock is more than double the Intel's 1300 MHz, which suggests it can respond quickly to burst workloads even if sustained throughput is lower. The 4 nm process node gives it a manufacturing advantage over the Intel's 6 nm node, which may translate into better efficiency per watt.

The use cases split along these lines. The Intel Arc A570M is the choice for sustained graphics workloads, gaming, and compute tasks where dedicated memory and high shading unit counts matter. The AMD Radeon 840M is the choice for battery-conscious portable systems that need basic graphics acceleration without the power draw of a discrete-class GPU. The database shows no head-to-head benchmark results, so the performance gap is inferred from the specification data and the Intel part's recorded benchmark score, but the margin in compute resources is so large that the Intel Arc A570M holds the clear performance advantage.
