The Radeon 820M has a 50th percentile ranking among all GPUs in the database, while the RTX 5000 Mobile Ada sits at the 21st percentile. This article breaks down the head-to-head results, architecture differences, use-case strengths, specification differences, and answers common questions based strictly on the recorded data.

Head-to-Head Benchmarks

The head-to-head benchmark list in the database is empty, so there are no direct side-by-side test scores comparing the AMD Radeon 820M and the NVIDIA RTX 5000 Mobile Ada Generation. However, the database does contain one benchmark result for the RTX 5000 Mobile Ada. In the 3DMark Steel Nomad DX12 test, the NVIDIA part scored 3596 points. The Radeon 820M has no benchmark scores recorded in the database, which means its average benchmark score is listed as 0. This absence of data makes direct numerical comparison impossible for the AMD part.

The RTX 5000 Mobile Ada has an average benchmark score of 3596, based on that single 3DMark Steel Nomad DX12 run. To place that score in context, the database provides nearest rival comparisons. The NVIDIA GeForce GT 545 averages 3594 points, which is 0.1% behind the RTX 5000 Mobile Ada. The NVIDIA GeForce GT 735M averages 3616 points, putting it 0.6% ahead of the RTX 5000 Mobile Ada. The NVIDIA GeForce GTX 1050 averages 3629 points, which is 0.9% ahead. The AMD Radeon HD 6770 averages 3649 points, placing it 1.5% ahead. These delta percentages show that the RTX 5000 Mobile Ada's recorded 3DMark Steel Nomad score lands in a narrow band alongside older desktop and mobile GPUs, within a couple of percentage points of each rival.

Given that the Radeon 820M has no recorded benchmark scores, the data cannot show any wins for either side. The wins counter in the database shows 0 wins for the AMD Radeon 820M and 0 wins for the NVIDIA RTX 5000 Mobile Ada Generation in head-to-head testing. This is a case where the absence of comparable data prevents a direct benchmark comparison. The only numerical benchmark evidence available is the RTX 5000 Mobile Ada's 3596 score in 3DMark Steel Nomad DX12, and its nearest rival deltas of 0.1%, -0.6%, -0.9%, and -1.5% against the four listed GPUs.

Architecture Differences

The AMD Radeon 820M uses the RDNA 3.5 architecture, specifically the Krackan Point 2 chip. It belongs to the Navi III IGP generation, which places it in the Strix Point Mobile family. The manufacturing process is 4 nm at TSMC. The transistor count and die size are listed as unknown in the database. The Radeon 820M is an integrated graphics processor, meaning it shares system memory and has no dedicated VRAM.

The NVIDIA RTX 5000 Mobile Ada Generation uses the Ada Lovelace architecture with the AD103 chip. It is part of the GeForce 50-series and belongs to the Ada-MW generation. The manufacturing process is 5 nm at TSMC.
