AMD Ryzen Z2 Go GPU vs NVIDIA RTX 2000 Mobile Ada Generation Comparison

The Verdict

The recorded data places the AMD Ryzen Z2 Go GPU and the NVIDIA RTX 2000 Mobile Ada Generation in two distinct performance classes. The RTX 2000 Mobile Ada holds the clear advantage in raw compute throughput, with FP32 performance of 12.99 TFLOPS versus the AMD chip's 4.147 TFLOPS. This translates to roughly three times the shader output capability. The RTX 2000 also leads in texture and pixel throughput, delivering 203.0 GTexel/s and 101.5 GPixel/s compared to 129.6 GTexel/s and 86.40 GPixel/s for the AMD part.

The AMD Ryzen Z2 Go GPU counters with a lower 28 W TDP and a larger 16 GB memory pool. The RTX 2000 Mobile Ada draws 50 W. The database shows both parts at the 50th percentile against all GPUs, but this is misleading without benchmark scores. The architectural data indicates the RTX 2000 is the higher-performance part, while the Z2 Go targets efficiency and capacity.

The RTX 2000 Mobile Ada is the pick for compute-heavy workloads, given its nearly 3.1x FP32 advantage and 2.5x bandwidth lead. The AMD Z2 Go suits power-constrained designs where 16 GB of memory matters more than peak throughput. The data does not support a single winner; it supports two different design goals.

Architecture Differences

The two GPUs come from different foundry nodes and architectures. The AMD Ryzen Z2 Go uses the Rembrandt+ chip on a 6 nm TSMC process, packing 13,100 million transistors into a 208 mm² die. The NVIDIA RTX 2000 Mobile Ada uses the AD107 chip on a 5 nm TSMC process, with 18,900 million transistors on a 159 mm² die. The density numbers reflect this: AMD achieves 63.0M transistors per mm², while NVIDIA reaches 118.9M per mm².

The AMD chip features RDNA 2.0 architecture with 768 shading units, 48 texture mapping units, and 32 raster operation pipelines. It includes 12 ray tracing cores but no tensor cores. The NVIDIA chip uses Ada Lovelace with 3072 shading units, 96 TMUs, and 48 ROPs. It includes 24 ray tracing cores and 96 tensor cores, marking a major feature gap in AI acceleration.

Memory subsystems differ substantially. The AMD part uses 16 GB of LPDDR5 on a 128-bit bus, yielding 102.4 GB/s bandwidth. The NVIDIA part uses 8 GB of GDDR6 on a 128-bit bus, yielding 256.0 GB/s. Both have the same bus width, but the GDDR6 memory runs at 2000 MHz (16 Gbps effective) versus the LPDDR5 at 800 MHz (6.4 Gbps effective).

Clock behavior also differs. The AMD chip has a base clock of 800 MHz and a boost of 2700 MHz. The NVIDIA chip has a base of 1635 MHz and a boost of 2115 MHz. The NVIDIA part starts higher but boosts less aggressively. The AMD part scales much higher, but its base is far lower, suggesting a wider dynamic range.

Both support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA part uses a PCIe 4.0 x16 interface, while the AMD part has no listed bus interface. The AMD display output is a single USB Type-C; the NVIDIA output is listed as portable device dependent.

Head-to-Head Benchmarks

The database contains no direct benchmark scores for either GPU. The head-to-head benchmark list is empty, and both parts show an average benchmark score of zero. This limits analysis to specification-derived comparisons. The FP32 throughput difference is the most significant: 12.99 TFLOPS versus 4.147 TFLOPS. The RTX 2000 Mobile Ada delivers 3.13 times the FP32 compute of the AMD Z2 Go.

Texture rate favors NVIDIA heavily. The RTX 2000 achieves 203.0 GTexel/s against 129.6 GTexel/s, a 1.57x advantage. Pixel rate shows a smaller gap: 101.5 GPixel/s versus 86.40 GPixel/s, which is 1.17x. The memory bandwidth gap is the second-largest difference after FP32: 256.0 GB/s versus 102.4 GB/s, a 2.5x lead for NVIDIA.

The FP16 comparison reveals a fundamental architectural split. The AMD part delivers 8.294 TFLOPS in FP16 at a 2:1 ratio relative to FP32. The NVIDIA part delivers 12.99 TFLOPS in FP16 at a 1:1 ratio. This means the NVIDIA GPU maintains its full throughput for half-precision work, while the AMD GPU halves its rate. For workloads using FP16, the RTX 2000 Mobile Ada leads by 1.57x, not the 3.13x seen in FP32.

Ray tracing resources favor NVIDIA by count: 24 RT cores versus 12. Tensor cores are exclusive to NVIDIA with 96 available. The AMD part has no tensor cores. The transistor density difference (118.9M versus 63.0M per mm²) suggests a more compact and potentially more efficient design for NVIDIA, though the TDP tells the opposite story at the board level.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins in memory capacity. Its 16 GB LPDDR5 pool doubles the NVIDIA part's 8 GB GDDR6. This matters for workloads that require large working sets, such as certain AI inference models or high-resolution texture caching. The AMD part also wins on power efficiency, with a 28 W TDP that is 22 W lower than the NVIDIA's 50 W. For thermally constrained handheld or portable designs, this is a decisive factor. The AMD part has a higher boost clock at 2700 MHz versus 2115 MHz, though its base clock is far lower at 800 MHz versus 1635 MHz.

The NVIDIA RTX 2000 Mobile Ada Generation wins in every throughput metric. FP32 compute is 12.99 TFLOPS versus 4.147 TFLOPS. Texture rate is 203.0 GTexel/s versus 129.6 GTexel/s. Pixel rate is 101.5 GPixel/s versus 86.40 GPixel/s. Memory bandwidth is 256.0 GB/s versus 102.4 GB/s. The NVIDIA part has more of every processing unit: 3072 shading units versus 768, 96 TMUs versus 48, 48 ROPs versus 32, 24 RT cores versus 12, and 96 tensor cores versus none. Its FP16 performance matches its FP32 at 12.99 TFLOPS, while the AMD part drops to 8.294 TFLOPS.

The NVIDIA part also wins on transistor efficiency. It packs 18,900 million transistors into a smaller 159 mm² die, versus 13,100 million on 208 mm². The density difference is nearly 2x. This suggests the AD107 chip is a more modern, denser design. The NVIDIA part has a higher base clock, which may indicate more consistent sustained performance without relying on boost behavior.
