AMD Ryzen Z2 GPU vs NVIDIA GeForce RTX 5080 Mobile Comparison

Where Each One Wins

The recorded benchmark data creates a clear split between these two parts. The AMD Ryzen Z2 GPU has no benchmark entries in the database, so every measured win belongs to the NVIDIA GeForce RTX 5080 Mobile. The NVIDIA part holds ten separate benchmark scores across DirectX 12, OpenCL, Vulkan, and Passmark suites, while the AMD part has zero recorded results. This means the use-case split is straightforward: the RTX 5080 Mobile is the only part with verified performance data, and it owns every category where measurements exist.

The RTX 5080 Mobile's percentile ranking reinforces this. It sits at the 81st percentile among all GPUs in the database, while the Ryzen Z2 GPU sits at the 50th percentile. The 50th percentile for the AMD part is a neutral midpoint, reflecting the absence of benchmark scores rather than a measured performance level. For the NVIDIA part, the 81st percentile places it above the majority of recorded GPUs, and its nearest rivals confirm this positioning.

Looking at the nearest rivals for the RTX 5080 Mobile, the delta values are small. The GeForce MX570 sits 0.1% ahead with an average score of 38,299, and the GeForce RTX 4080 Mobile sits 0.6% ahead with 38,135. The GeForce MX570 A trails by 0.9% with 38,691, and the AMD Radeon Pro 580X also trails by 0.9% with 38,706. These tight margins mean the RTX 5080 Mobile is clustered with these parts in aggregate scoring, but the individual test scores show where it excels.

Architecture Differences

The architectural gap between these two GPUs is substantial. The AMD Ryzen Z2 GPU uses the Hawk Point chip with RDNA 3.0 architecture, built on a 4 nm process at TSMC. The NVIDIA GeForce RTX 5080 Mobile uses the GB203 chip with Blackwell 2.0 architecture, also fabricated by TSMC but on a 5 nm process. The node difference is one nanometer, with AMD using the smaller process.

Transistor counts diverge sharply. The AMD part has 25,390 million transistors on a 178 mm² die, giving a transistor density of 142.6 million per mm². The NVIDIA part has 45,600 million transistors on a 378 mm² die, with a density of 120.6 million per mm². The AMD chip packs more transistors per area despite having fewer total transistors, while the NVIDIA chip uses a larger die to house nearly double the transistor count.

The memory architectures are completely different. The AMD Ryzen Z2 GPU uses 16 GB of LPDDR5X on a 128-bit bus, delivering 119.9 GB/s of bandwidth. The RTX 5080 Mobile uses 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s. That is a 7.5x bandwidth advantage for the NVIDIA part, which matters for memory-bound workloads.

Core counts also separate the two. The AMD part has 768 shading units, 48 texture mapping units, 32 ROPs, and 12 ray tracing cores. The NVIDIA part has 7,680 shading units, 240 TMUs, 96 ROPs, 60 RT cores, and 240 tensor cores. The NVIDIA part has 10x the shading units, 5x the TMUs, 3x the ROPs, and 5x the RT cores. The tensor cores are exclusive to NVIDIA, as the AMD part has no tensor core field filled.

Clock behavior differs in an interesting way. The AMD Ryzen Z2 GPU has a base clock of 800 MHz and a boost clock of 2700 MHz. The RTX 5080 Mobile has a base clock of 975 MHz and a boost clock of 1500 MHz. The AMD part boosts 1200 MHz higher, but the NVIDIA part starts from a higher base. The memory clocks tell a different story: AMD runs at 937 MHz with 7.5 Gbps effective, while NVIDIA runs at 1750 MHz with 28 Gbps effective.

Head-to-Head Benchmarks

Since the AMD Ryzen Z2 GPU has no benchmark entries, the head-to-head comparison is one-sided. Every score in the database belongs to the NVIDIA GeForce RTX 5080 Mobile, and the analysis must focus on what those scores indicate about the NVIDIA part's performance profile.

The strongest result for the RTX 5080 Mobile comes from Geekbench Vulkan, where it scores 169,754. The OpenCL score is close behind at 166,986. These two scores are within 1.6% of each other, showing consistent compute performance across API boundaries. The 3DMark Steel Nomad DX12 test produces a score of 4,952, which is a DirectX 12 workload that stresses modern rendering paths.

Passmark results show a varied picture. The G3D score is 27,711, which is the second-highest Passmark result for this part. The GPU compute score is 12,134, roughly 44% of the G3D score. The legacy DirectX tests produce lower numbers: DirectX 9 scores 314, DirectX 11 scores 253, DirectX 10 scores 171, and DirectX 12 scores 116. The G2D score is 1,095, which covers 2D graphics operations.

The DirectX 12 Passmark score of 116 is notably lower than the DX11 score of 253, which is an unusual inversion. The 3DMark DX12 result of 4,952 is a separate test, so the Passmark DX12 number should not be compared directly to it. The Passmark suite appears to stress different aspects of the GPU than the 3DMark workload.

The aggregate average benchmark score for the RTX 5080 Mobile is 38,349. Its nearest rival, the GeForce MX570, averages 38,299, a 0.1% delta. The RTX 4080 Mobile averages 38,135, a 0.6% delta. The MX570 A averages 38,691, a -0.9% delta, and the Radeon Pro 580X averages 38,706, also -0.9%. The RTX 5080 Mobile is essentially tied with these parts in aggregate terms, despite having a much higher individual peak score in Geekbench Vulkan.

The Verdict

The data points to a clear conclusion. The NVIDIA GeForce RTX 5080 Mobile is the only part with recorded benchmark scores, and those scores place it at the 81st percentile. The AMD Ryzen Z2 GPU has no benchmark results and sits at the 50th percentile as a default value.

The RTX 5080 Mobile's aggregate average score of 38,349 places it within 0.6% of the GeForce RTX 4080 Mobile and within 0.1% of the GeForce MX570. The individual scores show its strengths: a Geekbench Vulkan score of 169,754 and an OpenCL score of 166,986 indicate strong compute throughput. The Passmark G3D score of 27,711 and GPU compute score of 12,134 support this picture.

The AMD Ryzen Z2 GPU offers a different profile based on its specifications. It uses a smaller 4 nm process with higher transistor density, a lower 28 W TDP, and a much lower memory bandwidth of 119.9 GB/s. Its FP32 throughput of 8.294 TFLOPS is less than half of the NVIDIA part's 23.04 TFLOPS. The AMD part has 768 shading units versus 7,680, and 12 RT cores versus 60.

For users who need measured performance, the RTX 5080 Mobile is the only part with data. Its 81st percentile ranking and benchmark scores across DirectX 12, OpenCL, Vulkan, and Passmark suites provide a verified performance baseline. The Ryzen Z2 GPU's specifications suggest a low-power part, given the 28 W TDP and single USB Type-C display output, but no benchmark data exists to confirm its real-world behavior.

The RTX 5080 Mobile's nearest rivals all sit within 0.9% of its aggregate score, meaning the performance tier is crowded. The RTX 4080 Mobile, the MX570, the MX570 A, and the Radeon Pro 580X are all effectively tied with the RTX 5080 Mobile in average scoring. The individual benchmark strengths of the RTX 5080 Mobile, particularly in Vulkan and OpenCL, are where it separates itself.

The AMD part's 50th percentile and empty benchmark list means the database treats it as an unmeasured entity. The NVIDIA part's 81st percentile and full benchmark suite means the database treats it as a verified performer. For any workload where benchmark scores matter, the RTX 5080 Mobile is the data-supported choice.
