Where Each One Wins

The AMD Ryzen Z2 A GPU wins in power efficiency and memory capacity. Its 15 W TDP is dramatically lower than the NVIDIA part's 115 W, making it suited for compact, low-power systems. The 16 GB LPDDR5 memory capacity doubles the NVIDIA part's 8 GB, which matters for workloads that need large working sets rather than high throughput.

The NVIDIA RTX 3000 Mobile Ada Generation wins in nearly every raw performance category. Its shading unit count of 4608 is 9 times higher than AMD's 512. Texture mapping units number 144 versus 32, and render output units number 48 versus 16. The NVIDIA part has 36 ray tracing cores and 144 tensor cores, while the AMD part has 8 ray tracing cores and no tensor cores at all. The NVIDIA GPU's 15.62 TFLOPS FP32 throughput is roughly 9.5 times the AMD part's 1.638 TFLOPS. Pixel rate is 81.36 GPixel/s versus 25.60 GPixel/s, and texture rate is 244.1 GTexel/s versus 51.20 GTexel/s.

The NVIDIA GPU also wins on memory bandwidth at 256.0 GB/s versus 102.4 GB/s, and its GDDR6 memory operates at 16 Gbps effective versus 6.4 Gbps effective for the LPDDR5 memory in the AMD part. The NVIDIA GPU uses a PCIe 4.0 x16 bus interface, while the AMD part has no listed bus interface. The NVIDIA GPU also has a higher transistor density at 121.8M per mm² versus 14.7M per mm² for AMD, reflecting the more advanced 5 nm process node.

Architecture Differences

The AMD Ryzen Z2 A GPU uses the Van Gogh chip based on RDNA 2.0 architecture, fabricated on TSMC's 7 nm process. The NVIDIA RTX 3000 Mobile Ada Generation uses the AD106 chip based on Ada Lovelace architecture, fabricated on TSMC's 5 nm process. This process advantage allows NVIDIA to pack 22,900 million transistors into a 188 mm² die, achieving a transistor density of 121.8M per mm². AMD's smaller 163 mm² die holds only 2,400 million transistors, resulting in a density of 14.7M per mm².

The NVIDIA GPU includes 36 ray tracing cores and 144 tensor cores, enabling dedicated hardware for ray-traced rendering and AI-accelerated workloads. The AMD GPU includes 8 ray tracing cores but has no tensor cores. The NVIDIA part uses GDDR6 memory with a 128-bit bus, while AMD uses LPDDR5 memory with the same 128-bit bus width but lower effective speed.

The NVIDIA GPU is marked as an IGP with no power connectors and its display outputs are listed as "Portable Device Dependent." The AMD GPU has a display output of 1x USB Type-C. Both GPUs support DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA GPU has a PCIe 4.0 x16 bus interface, while no bus interface is listed for the AMD part.

Specification Differences

The two GPUs differ across nearly all specification fields. The AMD Ryzen Z2 A GPU operates at a base clock of 1000 MHz and boost clock of 1600 MHz, while the NVIDIA RTX 3000 Mobile Ada Generation runs at 1395 MHz base and 1695 MHz boost. Memory speed differs significantly: AMD uses LPDDR5 at 800 MHz with 6.4 Gbps effective, while NVIDIA uses GDDR6 at 2000 MHz with 16 Gbps effective.

Memory capacity differs, with AMD offering 16 GB versus NVIDIA's 8 GB. Both use a 128-bit memory bus, but bandwidth differs at 102.4 GB/s for AMD and 256.0 GB/s for NVIDIA. The shading unit count is 512 for AMD and 4608 for NVIDIA. TMUs are 32 versus 144, and ROPs are 16 versus 48. Ray tracing cores are 8 versus 36, and tensor cores are absent on AMD but present at 144 on NVIDIA.

Pixel rate is 25.60 GPixel/s for AMD and 81.36 GPixel/s for NVIDIA. Texture rate is 51.20 GTexel/s for AMD and 244.1 GTexel/s for NVIDIA. FP32 throughput is 1.638 TFLOPS for AMD and 15.62 TFLOPS for NVIDIA. FP16 throughput is 3.277 TFLOPS at a 2:1 ratio for AMD and 15.62 TFLOPS at a 1:1 ratio for NVIDIA.

The bus interface is PCIe 4.0 x16 for NVIDIA and not listed for AMD. Display outputs are 1x USB Type-C for AMD and "Portable Device Dependent" for NVIDIA.

Head-to-Head Benchmarks

The recorded data contains no head-to-head benchmark entries, no average benchmark scores, and no nearest rival comparisons for either GPU. Both parts hold a percentile rank of 50 against all GPUs in the database, and both have an average benchmark score of 0. The wins count is 0 for each GPU in head-to-head testing.

Without direct benchmark measurements, the specification data provides the only basis for comparison. The NVIDIA RTX 3000 Mobile Ada Generation's FP32 throughput of 15.62 TFLOPS is 9.5 times the AMD Ryzen Z2 A GPU's 1.638 TFLOPS. Texture rate of 244.1 GTexel/s is 4.8 times AMD's 51.20 GTexel/s. Pixel rate of 81.36 GPixel/s is 3.2 times AMD's 25.60 GPixel/s. Memory bandwidth of 256.0 GB/s is 2.5 times AMD's 102.4 GB/s.

The AMD part's advantages are in capacity and power. Its 16 GB memory is double the NVIDIA part's 8 GB. Its TDP of 15 W is 100 W lower than the NVIDIA part's 115 W. These are structural advantages rather than performance advantages. The NVIDIA GPU's transistor count of 22,900 million is 9.5 times AMD's 2,400 million, and its transistor density of 121.8M per mm² is 8.3 times AMD's 14.7M per mm².

The Verdict

The data indicates a clear performance hierarchy. The NVIDIA RTX 3000 Mobile Ada Generation dominates in raw compute, memory bandwidth, texture throughput, pixel throughput, and feature set. Its 4608 shading units, 144 TMUs, 48 ROPs, 36 ray tracing cores, and 144 tensor cores place it far ahead of the AMD Ryzen Z2 A GPU in every measured computational category. The 15.62 TFLOPS FP32 figure is roughly 9.5 times the AMD part's 1.638 TFLOPS, and the 256.0 GB/s memory bandwidth is 2.5 times higher.

The AMD Ryzen Z2 A GPU serves a different role. Its 15 W TDP makes it suitable for systems where power draw is the primary constraint. Its 16 GB memory capacity exceeds the NVIDIA part's 8 GB, which could benefit workloads that require larger memory allocations rather than higher bandwidth. The AMD part also carries a newer release date of 2024-12-31 versus 2023-03-20 for NVIDIA.

Users requiring maximum compute performance, ray tracing capability, AI acceleration through tensor cores, or high memory bandwidth should select the NVIDIA RTX 3000 Mobile Ada Generation. Users constrained by power limits or requiring larger memory capacity should consider the AMD Ryzen Z2 A GPU. The NVIDIA part's 115 W TDP indicates it requires a more substantial cooling solution and power delivery system, while the AMD part's 15 W TDP suggests implementation in low-power platforms. Both GPUs remain in active production, and both support DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, so API compatibility does not differentiate them.
