AMD Radeon 820M vs Intel Arc B570 Comparison

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries for the AMD Radeon 820M and Intel Arc B570. However, the Intel Arc B570 has a substantial set of recorded benchmark scores, while the AMD Radeon 820M has no individual benchmark results in the database. This asymmetry means the comparison must rely on the Arc B570's absolute scores and its position relative to other GPUs.

The Intel Arc B570 delivers a 3DMark Steel Nomad DX12 score of 2649. In Geekbench, it records 83514 in OpenCL and 96844 in Vulkan. The PassMark suite shows a G3D score of 14195, a GPU compute score of 7281, and legacy DirectX results of 164 in DX9, 118 in DX11, 72 in DX12, and 65 in DX10. The G2D score is 661.

The Arc B570's average benchmark score is 20556. Its nearest rivals in the database are the NVIDIA GeForce RTX 3070 Mobile at 20534 (delta 0.1%), the Intel Arc A750 at 20582 (delta -0.1%), the NVIDIA Quadro M4000M at 20480 (delta 0.4%), and the AMD Radeon R9 M390X at 20662 (delta -0.5%). These deltas are all within one percentage point, indicating that the Arc B570 sits in a tight performance cluster where the differences between these four GPUs are negligible in aggregate.

The Radeon 820M, by contrast, has no benchmark scores recorded. Its percentile rank among all GPUs is 50, which places it at the median of the database's distribution, but this percentile is derived from its specification profile rather than from measured benchmark runs. The Arc B570 holds a percentile rank of 65, meaning it sits above the median and within the upper third of all GPUs tracked.

Given the absence of measured results for the 820M, the quantitative comparison is limited to the Arc B570's recorded scores and its rival deltas. The data shows that the Arc B570 performs within 0.5% of the RTX 3070 Mobile, the Arc A750, the Quadro M4000M, and the R9 M390X. This cluster of near-identical average scores suggests that the Arc B570's performance tier is well established, and any of these four GPUs could be considered interchangeable in aggregate performance terms.

The Verdict

The database does not support a direct performance verdict between these two products because the Radeon 820M has no benchmark scores. The Arc B570 has an average score of 20556 and a percentile rank of 65. The Radeon 820M has a percentile rank of 50 with an average score of 0.

The Arc B570 is a discrete, dual-slot graphics card with a 150 W TDP, 2304 shading units, 144 texture mapping units, 80 raster output units, and 18 ray tracing cores. It uses 10 GB of GDDR6 memory on a 160-bit bus with 380.0 GB/s of bandwidth. Its boost clock is fixed at 2500 MHz. It requires a 450 W suggested power supply and a single 8-pin power connector.

The Radeon 820M is an integrated graphics processor with a 15 W TDP, 128 shading units, 8 texture mapping units, 4 raster output units, and 2 ray tracing cores. It uses system-shared memory with system-dependent bandwidth, so no dedicated memory specification exists. Its base clock is 400 MHz and its boost clock is 2800 MHz.

The data indicates that the Arc B570 is designed for a completely different performance class. The Radeon 820M's integrated nature and minimal resource counts place it in the entry-level mobile segment, while the Arc B570's discrete card format, high memory bandwidth, and large shader array target mainstream desktop gaming. The Arc B570's 11.52 TFLOPS FP32 throughput and 200.0 GPixel/s pixel rate far exceed the 820M's 716.8 GFLOPS and 11.20 GPixel/s. The verdict from the recorded data is that the Arc B570 is the higher-performing product by a wide margin, but exact deltas cannot be stated because the 820M lacks measured scores.

Where Each One Wins

The Intel Arc B570 wins in every measurable performance category where data exists. Its 11.52 TFLOPS FP32 throughput is 16 times the 820M's 716.8 GFLOPS. Its pixel rate of 200.0 GPixel/s is roughly 18 times the 820M's 11.20 GPixel/s. Its texture rate of 360.0 GTexel/s is roughly 16 times the 820M's 22.40 GTexel/s. Its 2304 shading units compare to 128, its 144 TMUs compare to 8, its 80 ROPs compare to 4, and its 18 ray tracing cores compare to 2.

The Arc B570's discrete memory subsystem gives it a decisive advantage in bandwidth-sensitive workloads. The 380.0 GB/s of dedicated GDDR6 bandwidth cannot be matched by the 820M's system-shared memory, which is listed as system dependent. For high-resolution textures, large scene complexity, and ray-traced effects, the Arc B570's 10 GB frame buffer and high bandwidth are the relevant factors.

The Radeon 820M's wins are limited to power efficiency and integration. Its 15 W TDP is one-tenth of the Arc B570's 150 W. It requires no power connectors, no dual-slot cooling, and no separate card installation. Its system-shared memory means no dedicated VRAM allocation is needed. The 820M also uses a smaller 4 nm process node compared to the 5 nm node of the Arc B570.

The 820M's higher boost clock of 2800 MHz versus the Arc B570's fixed 2500 MHz does not translate into a performance win given the massive difference in compute resources. The 820M's FP16 1:1 ratio indicates it does not accelerate FP16 workloads beyond FP32 rates, whereas the Arc B570's 2:1 ratio doubles its FP16 throughput.

For portable devices where power draw is the primary constraint, the 820M's 15 W envelope and integrated design are the clear advantages. For desktop systems with a 450 W power supply and a dual-slot PCIe card slot, the Arc B570's recorded benchmark scores and its position within 0.5% of four established GPUs make it the data-supported choice for measured performance. The database's percentile ranks confirm this split: the Arc B570 at the 65th percentile versus the 820M at the 50th percentile.
