Architecture Differences

Both GPUs belong to the same generation, Navi III IGP (Strix Point Mobile), and share the RDNA 3.5 architecture on TSMC's 4 nm process. The fundamental difference lies in the silicon: the Radeon 820M is based on the Krackan Point 2 chip, while the Radeon 860M is based on the Krackan Point chip. This chip separation drives every other architectural distinction.

The shading engine is where the gap is most pronounced. The Radeon 860M carries 512 shading units, exactly four times the 128 shading units of the Radeon 820M. Texture mapping units follow the same 4x ratio: 32 TMUs versus 8 TMUs. Render output units scale identically, with the Radeon 860M at 16 ROPs and the Radeon 820M at 4 ROPs. Ray tracing hardware also quadruples, from 2 RT cores in the Radeon 820M to 8 RT cores in the Radeon 860M. Neither GPU includes tensor cores in the recorded data.

Clock behavior differs as well. The Radeon 860M operates at a 600 MHz base and 3000 MHz boost, while the Radeon 820M runs at 400 MHz base and 2800 MHz boost. The higher clock rates on the Radeon 860M compound the shading unit advantage. Both parts are rated at 15 W TDP and use system shared memory with system dependent bandwidth, so the memory subsystem is not a differentiator.

Both chips are classified as integrated graphics (IGP) with no power connectors and portable device dependent display outputs. The production status is Active for both, with identical release dates of 2025-02-28. The predecessor for both is Navi II IGP.

The Verdict

The recorded data draws a clear line between these two integrated GPUs. The Radeon 860M is the stronger part by every measured architectural metric. It quadruples the shading units, texture units, render output units, and ray tracing cores of the Radeon 820M. It also runs at a higher base and boost clock. The Radeon 860M delivers 3.072 TFLOPS of FP32 performance against 716.8 GFLOPS for the Radeon 820M, a 4.29x advantage. Pixel rate is 48.00 GPixel/s versus 11.20 GPixel/s, and texture rate is 96.00 GTexel/s versus 22.40 GTexel/s.

The Radeon 820M carries the same architecture, process node, TDP, and API support. Its 50th percentile ranking is based on no recorded benchmark scores, so its position in the database reflects specifications rather than measured performance. The Radeon 860M has actual benchmark data: an average score of 26401 places it at the 72nd percentile, essentially matching dedicated mobile GPUs like the NVIDIA GeForce MX550 and desktop cards like the AMD Radeon RX 5700 XT 50th Anniversary.

For systems needing the highest integrated graphics throughput in this pair, the Radeon 860M is the choice supported by the measurements. The Radeon 820M is the lower-resource variant, with one quarter of the execution resources and lower clock speeds. Both share the same power envelope, so the Radeon 860M offers higher performance at the same TDP.

Head-to-Head Benchmarks

The database contains no direct head-to-head benchmark entries between the Radeon 820M and the Radeon 860M. The Radeon 820M has no recorded benchmark scores, so the comparison rests on the Radeon 860M's measured results and the architectural specifications of both parts.

The Radeon 860M's Geekbench OpenCL score of 22759 and Geekbench Vulkan score of 30043 average to 26401. This places it at the 72nd percentile of all GPUs in the database. The nearest rival, the NVIDIA GeForce MX550, scores 26421 and is 0.1% ahead. The NVIDIA GeForce RTX 5060 scores 26331, putting the Radeon 860M 0.3% ahead. The AMD Radeon RX 5700 XT 50th Anniversary scores 26553, 0.6% ahead of the Radeon 860M. The NVIDIA RTX A4000 scores 26683, 1.1% ahead. These margins are narrow, indicating the Radeon 860M performs in a tight band around dedicated graphics solutions.

The raw throughput figures reinforce the scale of the difference between the two integrated GPUs. The Radeon 860M's FP32 output of 3.072 TFLOPS is 4.29 times the Radeon 820M's 716.8 GFLOPS. Pixel throughput jumps from 11.20 GPixel/s to 48.00 GPixel/s, which is 4.29 times higher. Texture throughput moves from 22.40 GTexel/s to 96.00 GTexel/s, also a 4.29x multiplier. These ratios are consistent across every execution resource, confirming the Radeon 860M is a scaled implementation of the same architecture.

Clock speeds add a secondary effect. The Radeon 860M's 3000 MHz boost is 200 MHz higher than the Radeon 820M's 2800 MHz boost, and its 600 MHz base is 200 MHz higher. The combination of four times the resources and higher clocks means the Radeon 860M should sustain a proportionally larger advantage in workloads that scale with shading units, texture filtering, and pixel output.

Both GPUs share the 15 W TDP, so the Radeon 860M achieves its higher throughput within the same power envelope. The Radeon 820M, with one quarter of the execution resources, is the more limited part in this pair. The benchmark data, while only recorded for the Radeon 860M, shows that the larger chip competes with dedicated GPUs from NVIDIA. The Radeon 820M has no measured scores, leaving its 50th percentile ranking as a specification-based estimate.
