AMD Radeon RX 6800 XT vs NVIDIA RTX A3000 Mobile Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive victory for the AMD Radeon RX 6800 XT in the two shared benchmark tests. The AMD card wins both head-to-head comparisons, leaving the NVIDIA RTX A3000 Mobile without a single benchmark victory in this matchup.

In the Geekbench OpenCL test, the AMD Radeon RX 6800 XT scores 171,304 against 79,091 for the NVIDIA RTX A3000 Mobile. That is a delta of 53.8 percent in favor of the AMD card, meaning the desktop Radeon more than doubles the mobile NVIDIA GPU in raw compute performance. The OpenCL result is particularly telling because it exercises general-purpose GPU compute, a workload where both architectures should be able to stretch their legs.

The Vulkan result follows the same pattern. The AMD Radeon RX 6800 XT records 136,875 points, while the NVIDIA RTX A3000 Mobile manages 61,189 points. The delta here is 55.3 percent, an even larger gap than in OpenCL. Vulkan is a low-level graphics API, so this margin reflects not only raw shader throughput but also the efficiency of the graphics pipeline implementation. The AMD card's advantage in this test is substantial and consistent.

When looking at average benchmark scores across all recorded tests, the picture becomes more nuanced. The NVIDIA RTX A3000 Mobile has an average benchmark score of 70,140, while the AMD Radeon RX 6800 XT averages 48,477. This is because the NVIDIA card has only two recorded benchmarks in the database, both of which are compute-oriented, while the AMD card has eleven recorded tests, including several Passmark tests that score on very different numerical scales. The average score field should not be read as a direct head-to-head comparison across identical workloads, but rather as a summary of each card's full recorded test suite. The head-to-head data, which uses identical tests for both cards, is the more reliable comparison here.

The percentile rankings place the NVIDIA RTX A3000 Mobile at the 91st percentile of all GPUs, while the AMD Radeon RX 6800 XT sits at the 85th percentile. On the surface, this seems to contradict the head-to-head results, but the percentile is calculated against all GPUs in the database, not just against each other. The NVIDIA card's high percentile reflects its strong compute scores relative to the broader GPU population, while the AMD card's lower percentile is dragged down by its Passmark results, which include legacy DirectX 9 and DirectX 10 tests.

Where Each One Wins

The AMD Radeon RX 6800 XT wins in both head-to-head tests, taking both the OpenCL and Vulkan benchmarks. There are no recorded tests where the NVIDIA RTX 3000 Mobile comes out ahead. winsA in the database is 0, and winsB is 2.

For the AMD card, the wins are in raw compute-heavy workloads. The Geekbench OpenCL score of 171,304 is the highest single compute score recorded for either card, and the Vulkan score of 136,875 is likewise the higher of the two in that test. These are workloads that favor the AMD card's higher shader count, higher clock speeds, and substantially larger memory bandwidth.

The NVIDIA RTX A3000 Mobile does not win any recorded benchmark against the AMD card. Its strengths would have to be inferred from its percentile ranking and its average score, but in direct comparison, the data shows no category where it takes the lead. The NVIDIA card's 91st percentile ranking versus the AMD card's 85th percentile suggests that the mobile GPU is competitive within its own segment, but the head-to-head numbers are unambiguous.

For use-case segmentation, the AMD Radeon RX 6800 XT is the pick for any workload measured by OpenCL or Vulkan, which covers both general compute and modern graphics API rendering. The NVIDIA card has no recorded winning category in this comparison, so there is no database-supported use case where it beats the AMD card.
