AMD Ryzen Z2 Go GPU vs NVIDIA N1X 40SM Comparison

Head-to-Head Benchmarks

The database does not contain any synthetic or real-world benchmark scores for either the AMD Ryzen Z2 Go GPU or the NVIDIA N1X 40SM. Both entries have an average benchmark score of 0, and the head-to-head benchmark list is empty. Consequently, there are no recorded wins for either part in the head-to-head section. The percentileVsAllGpus field places both at the 50th percentile, which indicates a mid-pack position relative to all other GPUs in the database, but this is a relative ranking based on incomplete data rather than a measured performance result.

Without benchmark scores, the only quantitative performance indicators are the theoretical peak rates derived from the specification sheet. In raw compute throughput, the NVIDIA N1X 40SM delivers 24.02 TFLOPS of FP32 performance, which is 5.79 times higher than the AMD part's 4.147 TFLOPS. The NVIDIA device also exceeds the AMD part in pixel throughput, achieving 93.84 GPixel/s versus 86.40 GPixel/s, a difference of 8.6%. The texture rate gap is far larger: the NVIDIA solution reaches 750.7 GTexel/s, compared to 129.6 GTexel/s for AMD, a 5.79x advantage that mirrors the FP32 ratio.

Memory bandwidth shows a similar pattern. The NVIDIA N1X 40SM has a 256-bit bus with LPDDR5X memory rated at 8.5 Gbps effective, producing 273.2 GB/s. The AMD Ryzen Z2 Go GPU uses a 128-bit LPDDR5 bus at 6.4 Gbps effective, yielding 102.4 GB/s. The NVIDIA part's bandwidth is 2.67 times higher. The AMD device does clock higher in boost, 2700 MHz versus 2346 MHz for NVIDIA, but that advantage does not translate into a lead in any measured throughput metric.

Where Each One Wins

The AMD Ryzen Z2 Go GPU wins in the domain of power efficiency. Its TDP is listed as 28 W, a fixed, known figure that allows for predictable thermal and power envelope planning. The NVIDIA N1X 40SM has an unknown TDP, which means its power draw cannot be compared directly from the database. For scenarios where a strict power budget is the primary constraint, the AMD part's defined 28 W envelope is an advantage in that it is a known quantity, whereas the NVIDIA device's power requirements remain unspecified.

The AMD part also wins in software API compatibility. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 40SM lists all three APIs as N/A, meaning the database records no API support for that device. For any application relying on these standard graphics APIs, the AMD Ryzen Z2 Go GPU is the only one of the two with verified compatibility in the database.

The NVIDIA N1X 40SM wins in every raw performance category recorded. Its shading unit count is 5120 versus 768 for AMD, a 6.67x difference. Texture mapping units number 320 versus 48, and ROPs are 40 versus 32. The NVIDIA device also has 40 ray tracing cores and 160 tensor cores, while the AMD part has 12 ray tracing cores and no tensor cores at all. The NVIDIA memory subsystem is larger (128 GB versus 16 GB), faster (LPDDR5X versus LPDDR5), and wider (256-bit versus 128-bit). The NVIDIA part also has a larger die at 382 mm² versus 208 mm², though its transistor count is unknown, whereas AMD's is stated as 13,100 million.

Architecture Differences

The process nodes differ: AMD uses a 6 nm process from TSMC, while NVIDIA uses a 5 nm process, also from TSMC. The AMD chip is codenamed Rembrandt+ and uses the RDNA 2.0 architecture. The NVIDIA chip is designated GB20B and uses the Blackwell 2.0 architecture. Both are listed as active production parts, but they belong to different generations: AMD's generation is "Console GPU (AMD)" while NVIDIA's is "Blackwell IGP (N1x)".

The die sizes reveal a significant physical difference. AMD's die measures 208 mm² with 13,100 million transistors, giving a transistor density of 63.0M per mm². NVIDIA's die is larger at 382 mm², but its transistor count is unknown, so its density cannot be calculated from the database. The NVIDIA die is 83.7% larger by area.

Clock behavior differs as well. The AMD part has a base clock of 800 MHz and a boost of 2700 MHz, a 3.375x boost ratio. The NVIDIA part has a base of 741 MHz and a boost of 2346 MHz, a 3.17x ratio. The AMD part's memory clock is 800 MHz (6.4 Gbps effective), while NVIDIA's is 1067 MHz (8.5 Gbps effective).

The compute architecture is fundamentally different. AMD uses 768 shading units, 48 TMUs, and 32 ROPs. NVIDIA uses 5120 shading units, 320 TMUs, and 40 ROPs. Ray tracing resources differ: AMD has 12 RT cores, NVIDIA has 40. Tensor cores exist only on NVIDIA, with 160 units; AMD has none. FP16 performance also differs in ratio: AMD delivers 8.294 TFLOPS at a 2:1 ratio relative to FP32, while NVIDIA delivers 24.02 TFLOPS at a 1:1 ratio, meaning the NVIDIA part does not double FP16 throughput.

Memory technology and capacity are distinct. AMD ships 16 GB of LPDDR5 on a 128-bit bus. NVIDIA ships 128 GB of LPDDR5X on a 256-bit bus. The power delivery differs: AMD has a 28 W TDP and no power connectors, NVIDIA has no listed TDP and no power connectors. The bus interface is unspecified for AMD, while NVIDIA uses PCIe 5.0 x16. Display outputs are one USB Type-C for AMD and one HDMI for NVIDIA.

The Verdict

The data in the database points to a clear split between these two GPUs based on use case. For applications that require maximum raw compute throughput, the NVIDIA N1X 40SM is the only defensible choice. It leads in FP32 (24.02 TFLOPS versus 4.147 TFLOPS), texture rate (750.7 GTexel/s versus 129.6 GTexel/s), memory bandwidth (273.2 GB/s versus 102.4 GB/s), and memory capacity (128 GB versus 16 GB). It also has 160 tensor cores, which the AMD part lacks entirely, making the NVIDIA device better suited for workloads that depend on tensor operations.

For scenarios where a fixed, low power envelope is mandatory, the AMD Ryzen Z2 Go GPU is the part with a known TDP of 28 W. The NVIDIA part's TDP is not recorded, so its power draw cannot be verified against the same constraint. Additionally, the AMD part is the only one with confirmed support for DirectX 12 Ultimate, OpenGL, and Vulkan. If software compatibility with these APIs is a requirement, the NVIDIA device does not qualify based on the database records.

The release timeline also differs. The AMD part is dated 2024-12-31T17:00:00.000Z, while the NVIDIA part is dated 2026-05-31T17:00:00.000Z. The NVIDIA device is the newer product by approximately 17 months. Neither part has a launch MSRP in the database, and both sit at the 50th percentile versus all GPUs, though this percentile is based on missing benchmark data rather than measured scores. The verdict is straightforward: the NVIDIA N1X 40SM is the stronger compute device by every recorded performance metric, while the AMD Ryzen Z2 Go GPU is the only one with a specified power budget and verified graphics API support.
