AMD Ryzen Z2 A GPU vs NVIDIA GeForce RTX 5070 Ti Comparison

The Verdict

The database comparison between the AMD Ryzen Z2 A GPU and the NVIDIA GeForce RTX 5070 Ti is not a contest of equals. The recorded data shows two products from entirely different segments: the Ryzen Z2 A is a 15 W console-class GPU built for low-power mobile systems, while the RTX 5070 Ti is a 300 W desktop add-in board aimed at high-performance gaming and compute. The RTX 5070 Ti holds the 86th percentile across all GPUs in the database, whereas the Ryzen Z2 A sits at the 50th percentile. The RTX 5070 Ti has an average benchmark score of 49957, while the Ryzen Z2 A has no recorded benchmark scores in the database, meaning its percentile is based on specifications rather than measured tests.

For users who need a discrete desktop GPU with modern ray tracing, high memory bandwidth, and PCIe 5.0 connectivity, the RTX 5070 Ti is the only viable choice from the data. Its 16 GB GDDR7 memory, 896.0 GB/s bandwidth, and 43.94 TFLOPS FP32 performance place it in a completely different performance class. The Ryzen Z2 A, with its 16 GB LPDDR5 memory, 102.4 GB/s bandwidth, and 1.638 TFLOPS FP32, is suited for ultra-low-power embedded or handheld applications, not for competitive desktop gaming. The data indicates the RTX 5070 Ti is the appropriate pick for any scenario requiring substantial rasterization throughput, while the Ryzen Z2 A fits only in power-constrained environments where 15 W is the absolute limit.

Architecture Differences

The two GPUs share a manufacturing partner but diverge sharply in process technology and microarchitecture. The Ryzen Z2 A uses the Van Gogh chip on AMD's RDNA 2.0 architecture, built on TSMC's 7 nm process. It packs 2,400 million transistors into a 163 mm² die, yielding a transistor density of 14.7 million per mm². The RTX 5070 Ti uses the GB203 chip on NVIDIA's Blackwell 2.0 architecture, fabricated on TSMC's 5 nm node. It contains 45,600 million transistors across a 378 mm² die, resulting in a density of 120.6 million per mm². The RTX 5070 Ti has nearly 19 times the transistor count and roughly 8.2 times the die area, while achieving over 8 times the transistor density.

The shading pipeline differs drastically. The Ryzen Z2 A has 512 shading units, 32 texture mapping units, 16 raster operation units, and 8 ray tracing cores. It lacks tensor cores entirely. The RTX 5070 Ti has 8,960 shading units, 280 TMUs, 96 ROPs, 70 RT cores, and 280 tensor cores. The FP32 throughput gap is enormous: 1.638 TFLOPS for the Ryzen Z2 A versus 43.94 TFLOPS for the RTX 5070 Ti, a 26.8 times difference. FP16 performance also diverges: the Ryzen Z2 A delivers 3.277 TFLOPS with a 2:1 ratio, while the RTX 5070 Ti delivers 43.94 TFLOPS with a 1:1 ratio, meaning the NVIDIA part maintains full FP16 throughput without any halving penalty.

Memory architecture represents another fundamental split. The Ryzen Z2 A uses 16 GB of LPDDR5 on a 128-bit bus, delivering 102.4 GB/s. The RTX 5070 Ti uses 16 GB of GDDR7 on a 256-bit bus, delivering 896.0 GB/s, which is 8.75 times higher bandwidth. The Ryzen Z2 A has a single USB Type-C display output, while the RTX 5070 Ti provides 1x HDMI 2.1b and 3x DisplayPort 2.1b. The RTX 5070 Ti is dual-slot, measures 304 mm in length, 137 mm in height, and 48 mm in width, and requires a 16-pin power connector with a suggested 700 W PSU. The Ryzen Z2 A has no listed slot width, power connector, or PSU requirement, consistent with its 15 W TDP.

Head-to-Head Benchmarks

The database contains no head-to-head benchmark entries comparing these two GPUs directly. The Ryzen Z2 A has an empty benchmarks array, meaning there are no recorded scores for any test. The RTX 5070 Ti, however, has a full set of benchmark results. In 3DMark Steel Nomad DX12, it scores 6604. In Geekbench OpenCL, it scores 212363, and in Geekbench Vulkan, it scores 225122. Passmark results show a G3D score of 32974, a GPU compute score of 20203, and DirectX 9, 10, 11, and 12 scores of 351, 192, 300, and 127 respectively. The G2D score is 1332.

The RTX 5070 Ti's average benchmark score of 49957 places it near several rivals in the database. The AMD Radeon RX Vega 64 averages 50001, which is 0.1% higher than the RTX 5070 Ti. The Intel Arc A550M averages 49737, which is 0.4% lower. The AMD Radeon RX 6900 XT averages 50951, which is 2% higher. The AMD Radeon RX 6800 XT averages 48477, which is 3.1% lower. These deltas indicate the RTX 5070 Ti sits within a tight performance band around 50,000 points, with the RX 6900 XT at the top and the RX 6800 XT at the bottom of that cluster.

Because the Ryzen Z2 A has no benchmark scores, the database cannot compute a win count for either product. The winsA and winsB fields are both zero, and the head-to-head array is empty. The only measurable comparison comes from specification-derived metrics: the RTX 5070 Ti's FP32 performance is 26.8 times higher, its texture rate is 13.4 times higher, and its pixel rate is 9.2 times higher. The RTX 5070 Ti also has 17.5 times more shading units and 8.75 times more TMUs.

Where Each One Wins

The RTX 5070 Ti wins in every measured and spec-derived category where data exists. Its 43.94 TFLOPS FP32 and 43.94 TFLOPS FP16 (1:1) make it dominant for compute-heavy workloads such as GPU rendering, scientific simulation, and AI inference, especially given its 280 tensor cores. Its 896.0 GB/s memory bandwidth supports high-resolution texture streaming and large dataset processing. The 70 RT cores and 280 TMUs give it substantial ray tracing and texturing throughput. Its pixel rate of 235.4 GPixel/s and texture rate of 686.6 GTexel/s are 9.2 and 13.4 times higher than the Ryzen Z2 A's respective rates of 25.60 GPixel/s and 51.20 GTexel/s.

The Ryzen Z2 A wins in power efficiency and form factor flexibility. At 15 W TDP, it consumes 20 times less power than the RTX 5070 Ti's 300 W. It requires no external power connector, no dual-slot cooling solution, and no 700 W PSU. Its single USB Type-C output and lack of dimension specifications suggest integration into compact, low-power devices. The Ryzen Z2 A's 50th percentile ranking, while below the RTX 5070 Ti's 86th percentile, still indicates it is a mid-range performer among all GPUs, which is notable given its minimal power envelope.

The benchmark distribution for the RTX 5070 Ti shows strengths across API generations. Its Passmark DirectX 9 score of 351 and DirectX 11 score of 300 indicate solid legacy API performance, while its DirectX 12 score of 127 and 3DMark Steel Nomad score of 6604 reflect modern workload capability.
