AMD Ryzen Z2 GPU vs NVIDIA GeForce RTX 4090 Mobile Comparison

Where Each One Wins

The recorded data shows a complete separation of workloads between these two mobile graphics processors. The AMD Ryzen Z2 GPU has no benchmark entries in the database, while the NVIDIA GeForce RTX 4090 Mobile has nine recorded test scores. The NVIDIA part therefore holds every measurable win in the database.

The RTX 4090 Mobile dominates the synthetic suites where it was tested. Its Passmark G3D score of 27212 represents the strongest overall graphics result among its recorded tests. The Geekbench OpenCL score of 180831 and Geekbench Vulkan score of 170774 both indicate substantial compute throughput. The Passmark GPU Compute score of 12347 further confirms strong general-purpose compute capability.

The older DirectX legacy tests show a different pattern within the NVIDIA part itself. The Passmark DirectX 9 score of 310 exceeds the DirectX 11 score of 262, while the DirectX 10 score drops to 173 and DirectX 12 falls to 107. This ordering suggests the RTX 4090 Mobile delivers its highest legacy rasterization performance under DirectX 9, with progressively lower scores in newer API versions. The Passmark G2D score of 984 measures 2D graphics work separately from the 3D suites.

The AMD Ryzen Z2 GPU records no benchmark scores at all, placing it at the 50th percentile of all GPUs in the database. The RTX 4090 Mobile sits at the 84th percentile with an average benchmark score of 43667. The absence of AMD data means no direct comparison can be made on equal terms; the database simply contains no measurements for the Ryzen Z2 GPU.

The Verdict

The data supports only one selection based on recorded measurements: the NVIDIA GeForce RTX 4090 Mobile. It has nine benchmark scores, an 84th percentile ranking, and an average score of 43667. The AMD Ryzen Z2 GPU has zero scores, a 50th percentile ranking, and an average score of 0.

The RTX 4090 Mobile sits close to several established desktop-class parts in the database. The nearest rival, the NVIDIA RTX A6000, posts an average score of 44075, which is 0.9% above the RTX 4090 Mobile. The NVIDIA Quadro M6000 trails by 0.8% with a score of 43301. The GeForce RTX 5050 Mobile is 0.9% behind at 43268, and the Quadro M6000 24 GB matches that 0.9% gap with a score of 43262. These margins place the RTX 4090 Mobile in a tight cluster of high-end performers.

For the AMD Ryzen Z2 GPU, the database records no performance evidence. It is an active product with a 4 nm process and RDNA 3.0 architecture, but without benchmark entries its real-world standing cannot be assessed from this data. Any selection between the two must therefore rely on the only measured part, which is the NVIDIA.

Head-to-Head Benchmarks

No head-to-head benchmark entries exist between the AMD Ryzen Z2 GPU and the NVIDIA GeForce RTX 4090 Mobile. The database lists zero wins for either part in direct comparison. All available measurements belong exclusively to the NVIDIA side.

The strongest individual result for the RTX 4090 Mobile is the Geekbench OpenCL score of 180831. The Vulkan test follows at 170774, a difference of 10057 points. These two scores indicate the part's compute performance under different API front-ends. The Passmark GPU Compute score of 12347 is substantially lower than either Geekbench figure, which reflects the different workloads and scoring methodologies across test suites.

Within the Passmark DirectX family, the RTX 4090 Mobile scores 310 in DirectX 9, 262 in DirectX 11, 173 in DirectX 10, and 107 in DirectX 12. The DirectX 9 result leads the group, while DirectX 12 trails by 203 points. The G3D score of 27212 is the headline graphics figure, and the G2D score of 984 covers 2D operations.

The average benchmark score of 43667 combines all nine recorded tests. The nearest rivals all fall within roughly one percentage point of this figure: the RTX A6000 at 44075, the Quadro M6000 at 43301, the RTX 5050 Mobile at 43268, and the Quadro M6000 24 GB at 43262. The delta percentages range from 0.8% to 0.9% below for three rivals and 0.9% above for the RTX A6000.
