AMD Ryzen Z2 A GPU vs NVIDIA GeForce RTX 4050 Mobile Comparison

Where Each One Wins

The AMD Ryzen Z2 A GPU and NVIDIA GeForce RTX 4050 Mobile occupy very different positions in the database. The RTX 4050 Mobile has a complete benchmark record, while the Ryzen Z2 A GPU has no recorded benchmark scores. This means the recorded data cannot directly confirm any single workload victory for the AMD part. The database lists zero wins for the AMD GPU and zero wins for the NVIDIA GPU in head-to-head testing, as no direct comparisons exist.

The RTX 4050 Mobile, by contrast, has measurable results across nine separate tests. Its highest relative performance appears in synthetic compute and graphics workloads. The PassMark G3D score of 14423 and PassMark GPU Compute score of 5947 indicate strong general-purpose rendering and compute capability. The Geekbench OpenCL score of 74748 and Vulkan score of 75235 confirm that the NVIDIA part excels in cross-platform compute APIs. Its PassMark DirectX 9 score of 184 stands as its best legacy API result, while DirectX 11 at 130 and DirectX 10 at 79 show scaling across older graphics interfaces. The DirectX 12 score of 61 is the lowest of its API suite.

The Ryzen Z2 A GPU instead presents its advantages through specifications rather than measured results. It pairs a 15 W TDP with 16 GB of LPDDR5 memory on a 128 bit bus, a configuration that leans toward power-conscious, memory-capacious designs. The RTX 4050 Mobile consumes 50 W, uses 6 GB of GDDR6 on a 96 bit bus, and delivers 192.0 GB/s of bandwidth. The AMD part offers 102.4 GB/s. The data suggests the AMD GPU would win in memory capacity and power efficiency, while the NVIDIA GPU holds the advantage in raw throughput and measured benchmark scores.

Architecture Differences

The two GPUs come from different architectural lineages. The AMD Ryzen Z2 A GPU uses the Van Gogh chip built on RDNA 2.0, fabricated on TSMC's 7 nm process. It contains 2,400 million transistors on a 163 mm² die, yielding a transistor density of 14.7 million per square millimeter. The NVIDIA GeForce RTX 4050 Mobile uses the AD107 chip based on Ada Lovelace, built on TSMC's 5 nm node. It packs 18,900 million transistors into a 159 mm² die, a density of 118.9 million per square millimeter. The density gap is stark: the NVIDIA chip fits nearly eight times more transistors per area.

Compute resources differ significantly. The AMD GPU has 512 shading units, 32 texture mapping units, and 16 ROPs. It also includes 8 ray tracing cores and no tensor cores. The NVIDIA GPU has 2,560 shading units, 80 TMUs, and 48 ROPs, along with 20 ray tracing cores and 80 tensor cores. The NVIDIA part multiplies the AMD GPU's shading units by five, its TMUs by 2.5, and its ROPs by three. Tensor core presence gives the RTX 4050 Mobile a dedicated path for AI workloads that the AMD GPU lacks entirely.

Clock behavior also separates the two. The AMD GPU runs at a 1000 MHz base and 1600 MHz boost. The NVIDIA GPU starts at 1455 MHz base and reaches 1755 MHz boost. Memory clocks differ as well: the AMD part uses 800 MHz with 6.4 Gbps effective transfer, while the NVIDIA part runs at 2000 MHz with 16 Gbps effective. The NVIDIA memory clock is 2.5 times higher in effective transfer rate.

The AMD GPU is classified under Console GPU (AMD) generation, while the NVIDIA part belongs to GeForce 40 Mobile. The AMD part has no listed bus interface, whereas the NVIDIA part uses PCIe 4.0 x8. Display output also differs: the AMD GPU offers 1x USB Type-C, while the NVIDIA part is described as Portable Device Dependent. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API compatibility is identical.

Head-to-Head Benchmarks

No direct head-to-head benchmark entries exist in the database for these two GPUs. The head-to-head benchmark array is empty, and the win counters read zero for both sides. The only quantitative comparison possible comes from the RTX 4050 Mobile's own benchmark suite and its nearest rival data.

The RTX 4050 Mobile averages 19049 in benchmark scores, placing it at the 63rd percentile of all GPUs. Its nearest rivals cluster tightly around this mark. The AMD Radeon RX 6600 scores 19036, a delta of 0.1 percent. The NVIDIA Quadro K6000 scores 19030, also 0.1 percent ahead of the RTX 4050 Mobile. The NVIDIA Tesla K20m scores 19089, which is 0.2 percent behind the RTX 4050 Mobile. The NVIDIA RTX 2000 Ada Generation scores 18954, 0.5 percent behind. The RTX 4050 Mobile sits within a half percent of all four rivals, indicating its average score is highly competitive with a broad range of desktop and workstation parts.

The Ryzen Z2 A GPU has an average benchmark score of zero and sits at the 50th percentile. With no benchmark entries, the database cannot establish a performance delta against the RTX 4050 Mobile or any other GPU. The AMD part's 1.638 TFLOPS FP32 throughput compares to the NVIDIA part's 8.986 TFLOPS, a 5.5-fold difference in raw floating-point rate. Texture rate shows a similar gap: 51.20 GTexel/s for AMD versus 140.4 GTexel/s for NVIDIA. Pixel rate measures 25.60 GPixel/s for AMD versus 84.24 GPixel/s for NVIDIA. These recorded specification values indicate the NVIDIA GPU would dominate in any purely compute-bound or fill-rate-bound workload, though no benchmark confirms this directly.

The RTX 4050 Mobile's own scores show internal variation. Its PassMark G3D score of 14423 is roughly 2.4 times its GPU Compute score of 5947. Its Geekbench Vulkan score of 75235 slightly exceeds its OpenCL score of 74748, a 0.6 percent difference. Among PassMark DirectX tests, the DirectX 9 score of 184 leads, DirectX 11 follows at 130, DirectX 10 trails at 79, and DirectX 12 sits lowest at 61. This pattern suggests the NVIDIA part performs better under older API paths than under modern DirectX 12 in these specific tests.

The Verdict

The recorded data supports a clear split. The NVIDIA GeForce RTX 4050 Mobile is the choice for measured performance. Its average benchmark score of 19049, 63rd percentile ranking, and consistent scores across Geekbench and PassMark tests give it a documented performance profile. Its 8.986 TFLOPS FP32 throughput, 84.24 GPixel/s pixel rate, and 140.4 GTexel/s texture rate place it far ahead of the AMD part in raw specification terms. The presence of 80 tensor cores and 20 ray tracing cores also gives it dedicated hardware for AI and ray tracing that the AMD GPU cannot match.

The AMD Ryzen Z2 A GPU offers a different set of advantages from its specifications. Its 16 GB of LPDDR5 memory doubles the NVIDIA part's capacity, and its 128 bit bus is wider. Its 15 W TDP is one third of the NVIDIA part's 50 W, indicating a far lower power envelope. Its smaller transistor count and older 7 nm process suggest a simpler, more power-conscious design. For systems where memory capacity and power draw matter more than raw throughput, the AMD part's configuration is the one the data favors.

The RTX 4050 Mobile also carries an active production status and a successor in GeForce 50 Mobile. The Ryzen Z2 A GPU has no listed predecessor or successor. The database shows the NVIDIA part as the stronger performer in every measured category, while the AMD part remains a specification-driven alternative with no benchmark confirmation of its capabilities.
