AMD Ryzen Z2 A GPU vs NVIDIA RTX 500 Mobile Ada Generation Comparison

The Verdict

The recorded database profile for the AMD Ryzen Z2 A GPU and the NVIDIA RTX 500 Mobile Ada Generation places both at the 50th percentile among all GPUs, yet their specifications diverge sharply. The AMD part is a low-power, console-class chip with 16 GB of LPDDR5 memory, designed for a 15 W envelope. The NVIDIA part is a mobile workstation chip with 4 GB of GDDR6, a 35 W envelope, and far higher compute throughput. Based strictly on the data, the AMD Ryzen Z2 A suits workloads requiring large memory capacity at minimal power draw, while the NVIDIA RTX 500 Mobile Ada Generation suits tasks demanding raw shader throughput, ray tracing, and tensor acceleration. Neither part has benchmark scores in the database, so the analysis relies entirely on architecture and specification differences.

Architecture Differences

The AMD Ryzen Z2 A GPU uses the Van Gogh chip, built on RDNA 2.0 architecture, and is classified under the Console GPU (AMD) generation. It is fabricated on TSMC's 7 nm process with 2,400 million transistors on a 163 mm² die, yielding a transistor density of 14.7M per mm². The NVIDIA RTX 500 Mobile Ada Generation uses the AD107 chip, built on Ada Lovelace architecture, and belongs to the Ada-MW (x000A) generation. It is fabricated on TSMC's 5 nm process with 18,900 million transistors on a 159 mm² die, yielding a transistor density of 118.9M per mm². The NVIDIA chip packs nearly eight times more transistors into a slightly smaller die, a direct consequence of the denser 5 nm process.

The AMD part integrates 512 shading units, 32 texture mapping units, 16 raster output units, and 8 ray tracing cores. The NVIDIA part integrates 2,048 shading units, 64 texture mapping units, 32 raster output units, 16 ray tracing cores, and 64 tensor cores. NVIDIA's shading unit count is four times higher, and its ray tracing core count is double. The AMD part has no tensor cores listed, while NVIDIA's 64 tensor cores enable dedicated AI acceleration. Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, so API-level feature parity exists.

Memory architecture differs fundamentally. The AMD part uses 16 GB of LPDDR5 on a 128-bit bus, delivering 102.4 GB/s of bandwidth. The NVIDIA part uses 4 GB of GDDR6 on a 64-bit bus, delivering 128.0 GB/s. NVIDIA achieves higher bandwidth despite a narrower bus because its memory runs at 2000 MHz (16 Gbps effective), while AMD's memory runs at 800 MHz (6.4 Gbps effective). The AMD part's fourfold larger capacity comes at the cost of lower peak bandwidth.

Head-to-Head Benchmarks

The database records no head-to-head benchmark scores for these two GPUs, so direct performance comparisons must be inferred from specification data. The NVIDIA part's FP32 throughput is 8.294 TFLOPS, which is 5.07 times higher than the AMD part's 1.638 TFLOPS. In FP16, NVIDIA delivers 8.294 TFLOPS at a 1:1 ratio, while AMD delivers 3.277 TFLOPS at a 2:1 ratio. NVIDIA's FP16 throughput is 2.53 times higher. Pixel rate on NVIDIA is 64.80 GPixel/s versus 25.60 GPixel/s on AMD, a 2.53 times advantage. Texture rate on NVIDIA is 129.6 GTexel/s versus 51.20 GTexel/s on AMD, a 2.53 times advantage. These ratios indicate that NVIDIA scales roughly proportionally across all rasterization metrics.

Clock speeds also favor NVIDIA. The AMD part has a base clock of 1000 MHz and a boost clock of 1600 MHz. The NVIDIA part has a base clock of 1485 MHz and a boost clock of 2025 MHz. NVIDIA's base clock is 48.5% higher, and its boost clock is 26.6% higher. Combined with the larger shading unit count, the clock advantage amplifies NVIDIA's compute lead. However, the AMD part consumes 15 W versus NVIDIA's 35 W, so AMD's efficiency per watt is superior in raw FLOPs per watt terms, though the database does not provide a direct efficiency metric.

Where Each One Wins

The AMD Ryzen Z2 A GPU wins in scenarios where memory capacity and power efficiency are the primary constraints. Its 16 GB of LPDDR5 memory is four times larger than NVIDIA's 4 GB, making it suited for workloads that require large datasets resident in memory, such as integrated graphics configurations in handheld or console-style devices. Its 15 W TDP is less than half of NVIDIA's 35 W, so it fits into power-constrained environments where thermal dissipation is limited. The AMD part's 1x USB Type-C display output also indicates a single-cable connectivity design, which aligns with compact form factors. Its production status is Active, and it was released on 2024-12-31, making it a more recent entry in the database.

The NVIDIA RTX 500 Mobile Ada Generation wins in scenarios where compute throughput, ray tracing, and tensor acceleration are the priorities. Its 8.294 TFLOPS FP32 and FP16 performance is more than five times higher than AMD's FP32 and more than double its FP16, so it delivers substantially higher shader and compute performance. Its 16 ray tracing cores and 64 tensor cores provide dedicated hardware for ray-traced rendering and AI workloads, which the AMD part lacks entirely. Its 64.80 GPixel/s pixel rate and 129.6 GTexel/s texture rate are both 2.53 times higher, so rasterization-heavy tasks benefit. Its 128.0 GB/s memory bandwidth, despite a narrower 64-bit bus, exceeds AMD's 102.4 GB/s, so bandwidth-sensitive operations see a 25% advantage. The NVIDIA part uses a PCIe 4.0 x8 bus interface, which the AMD part does not list, and its IGP slot width indicates integration into portable devices. Its predecessor and successor are listed in the database, showing a defined product lineage. The NVIDIA part was released on 2024-02-25, earlier than the AMD part, and both are Active in production.
