Architecture Differences

The AMD Radeon 820M is built on the RDNA 3.5 architecture, manufactured on a 4 nm process at TSMC. It belongs to the Navi III IGP generation for Strix Point Mobile, with the chip designated Krackan Point 2. The GPU integrates 128 shading units, 8 texture mapping units, 4 render output units, and 2 ray tracing cores. Its FP32 performance is measured at 716.8 GFLOPS, with FP16 performance matching at 716.8 GFLOPS in a 1:1 ratio. The pixel rate is 11.20 GPixel/s and the texture rate is 22.40 GTexel/s. Power consumption is rated at 15 W TDP, and the bus interface is PCIe 4.0 x8.

The Intel Arc A570M uses the Xe-HPG architecture, specifically the DG2-256 chip from the Alchemist generation (Arc 5 Mobile). It is fabricated on a 6 nm TSMC process with 11,500 million transistors on a 269 mm² die, yielding a transistor density of 42.8M per mm². The GPU contains 2048 shading units, 128 TMUs, 64 ROPs, and 16 RT cores. FP32 performance reaches 5.325 TFLOPS, while FP16 performance is 10.65 TFLOPS in a 2:1 ratio. The pixel rate is 83.20 GPixel/s and the texture rate is 166.4 GTexel/s. The TDP is 75 W, also using a PCIe 4.0 x8 interface.

Both GPUs support the same API set: DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. Both are classified as IGP (integrated graphics processor) for slot width, meaning they are designed for portable devices with device-dependent display outputs. Neither GPU has a dedicated power connector listed, and neither has a launch MSRP in the database.

The Radeon 820M's predecessor is listed as Navi II IGP, while the Arc A570M has no listed predecessor. Both GPUs are currently in Active production status. The Radeon 820M's memory clock is listed as "System Shared" with system-dependent bandwidth, whereas the Arc A570M operates its GDDR6 memory at 1750 MHz with 14 Gbps effective speed.

The Verdict

The benchmark data shows a clear performance hierarchy. The Intel Arc A570M holds one recorded OpenCL benchmark score of 58,239, placing it at the 88th percentile of all GPUs in the database. The AMD Radeon 820M has no recorded benchmark scores and sits at the 50th percentile. The Arc A570M's nearest rivals in the database include the AMD Radeon RX 6950 XT with an average score of 58,392 (a 0.3% difference), the AMD Radeon RX 5600 OEM at 58,085 (0.3% higher delta for the Arc), the NVIDIA P102-100 at 58,528 (0.5% difference), and the AMD Radeon PRO V710 at 58,657 (0.7% difference). The Arc A570M effectively trades positions within a narrow band around these scores.

For users choosing between these two GPUs, the data indicates the Arc A570M delivers substantially higher compute throughput, with over 7 times the FP32 performance (5.325 TFLOPS versus 716.8 GFLOPS), 16 times the shading units, and 4 times the pixel rate. The dedicated 8 GB GDDR6 memory with 224.0 GB/s bandwidth versus system-shared memory gives the Arc a decisive advantage in memory-intensive workloads. The Radeon 820M, however, operates at a much lower 15 W TDP compared to the Arc's 75 W, making it suitable for power-constrained portable designs. The Arc A570M is the clear choice for applications requiring substantial graphics compute, while the Radeon 820M fits scenarios where power efficiency is the dominant constraint.

Specification Differences

The two GPUs differ across nearly every specification field. The AMD Radeon 820M 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 Radeon 820M has no listed transistor count or die size, whereas the Arc A570M has 11,500 million transistors on a 269 mm² die.

Clock speeds differ significantly: the Radeon 820M has a 400 MHz base and 2800 MHz boost, while the Arc A570M has a 900 MHz base and 1300 MHz boost. Memory configurations are entirely different: the Radeon 820M uses system-shared memory with system-dependent bandwidth, while the Arc A570M has 8 GB GDDR6 on a 128-bit bus with 224.0 GB/s bandwidth.

Compute resources differ by an order of magnitude: the Radeon 820M has 128 shading units, 8 TMUs, 4 ROPs, and 2 RT cores, versus the Arc A570M's 2048 shading units, 128 TMUs, 64 ROPs, and 16 RT cores. Pixel rate is 11.20 GPixel/s versus 83.20 GPixel/s, and texture rate is 22.40 GTexel/s versus 166.4 GTexel/s. FP32 performance is 716.8 GFLOPS versus 5.325 TFLOPS, and FP16 is 716.8 GFLOPS (1:1) versus 10.65 TFLOPS (2:1).

TDP differs from 15 W to 75 W. Release dates differ: the Radeon 820M launched February 28, 2025, while the Arc A570M launched July 31, 2023. The Radeon 820M lists Navi II IGP as a predecessor, while the Arc A570M has none. The Radeon 820M has no benchmark scores in the database, while the Arc A570M has one OpenCL score of 58,239 and an average benchmark score of 58,239.

Head-to-Head Benchmarks

The head-to-head benchmark comparison in the database contains no entries, so no direct match results exist between these two GPUs. However, the recorded data for each GPU separately provides a basis for comparison.

The Intel Arc A570M's OpenCL score of 58,239 places it in the 88th percentile. Its nearest rivals show how tightly clustered this performance level is: the AMD Radeon RX 6950 XT scores 58,392, just 0.3% higher; the AMD Radeon RX 5600 OEM scores 58,085, 0.3% lower; the NVIDIA P102-100 scores 58,528, 0.5% higher; and the AMD Radeon PRO V710 scores 58,657, 0.7% higher. The Arc A570M sits comfortably within this peer group, with all deltas under 1%.

The AMD Radeon 820M has no recorded benchmark scores, which means the database cannot provide a direct numerical comparison. Its 50th percentile ranking indicates it falls in the middle of the performance distribution, but without scores, specific performance deltas cannot be calculated.

The raw specification data provides the clearest comparative signal. The Arc A570M's FP32 throughput of 5.325 TFLOPS is approximately 7.4 times the Radeon 820M's 716.8 GFLOPS. Its texture rate of 166.4 GTexel/s is approximately 7.4 times the Radeon 820M's 22.40 GTexel/s. The pixel rate of 83.20 GPixel/s is approximately 7.4 times the Radeon 820M's 11.20 GPixel/s. The shading unit count of 2048 versus 128 represents a 16-fold difference. The RT core count of 16 versus 2 represents an 8-fold difference.

The memory bandwidth gap is even more pronounced: the Arc A570M's 224.0 GB/s dedicated bandwidth versus system-shared memory with system-dependent bandwidth means the Arc operates with predictable, high-throughput memory access while the Radeon 820M's performance depends entirely on the host system's memory configuration.

Where Each One Wins

The Intel Arc A570M wins decisively in raw compute performance. Its 5.325 TFLOPS FP32 throughput, 10.65 TFLOPS FP16 throughput, and 83.20 GPixel/s pixel rate place it in a performance class that its nearest rivals in the database confirm: it trades within 0.7% of the AMD Radeon RX 6950 XT, the AMD Radeon RX 5600 OEM, the NVIDIA P102-100, and the AMD Radeon PRO V710. For applications that stress shading units, texture filtering, or ray tracing, the Arc A570M's 2048 shading units, 128 TMUs, and 16 RT cores provide a substantial resource advantage. The dedicated 8 GB GDDR6 memory with 224.0 GB/s bandwidth ensures memory bandwidth is not a bottleneck for large datasets or high-resolution textures.

The AMD Radeon 820M wins in power efficiency. Its 15 W TDP is one-fifth the Arc A570M's 75 W TDP. For portable devices where thermal and power budgets are tight, this difference is significant. The Radeon 820M also operates at a higher boost clock of 2800 MHz versus the Arc's 1300 MHz, though this advantage is overwhelmed by the Arc's much larger compute resource pool. The Radeon 820M's system-shared memory approach eliminates the need for dedicated VRAM, which can reduce system cost and complexity in designs where dedicated graphics memory is not required.

The production status of both GPUs is Active, meaning both remain available for current system designs. The Radeon 820M's 2025 release date makes it a newer design, while the Arc A570M's 2023 release date shows it has been in the market longer. The Radeon 820M's predecessor, Navi II IGP, indicates a lineage of integrated graphics, while the Arc A570M has no listed predecessor in the database.

For workloads dominated by graphics compute, rendering, or machine learning inference, the Arc A570M is the appropriate choice based on the recorded data. For power-sensitive integrated designs where moderate graphics capability suffices, the Radeon 820M fits the requirement. The benchmark percentile ranking (88th versus 50th) confirms the Arc A570M's higher overall performance position in the database.
