AMD Ryzen Z2 A GPU vs NVIDIA N1X 48SM Comparison

Head-to-Head Benchmarks

The recorded data contains no benchmark scores for either the AMD Ryzen Z2 A GPU or the NVIDIA N1X 48SM. Both entries list an average benchmark score of 0, and the head-to-head benchmark table is empty. Consequently, there are no measured wins for either part, and the win counters (winsA and winsB) both stand at 0. Without benchmark results, direct performance comparisons cannot be established from the database. The percentile ranking for both GPUs is 50, placing them at the midpoint of all tracked GPUs, but this percentile is not derived from any listed benchmark data. The absence of scores means that any claims about relative speed, efficiency, or gaming capability must rely solely on the architectural and specification differences documented below.

FAQ

Q: What is the FP32 floating-point performance of each GPU?

A: The AMD Ryzen Z2 A GPU delivers 1.638 TFLOPS of FP32 compute, while the NVIDIA N1X 48SM delivers 28.83 TFLOPS. This represents a substantial 17.6x gap in raw single-precision throughput, with the NVIDIA part holding a decisive advantage.

Q: How much memory does each GPU offer, and what type is it?

A: The AMD Ryzen Z2 A GPU has 8 ray tracing cores and no tensor cores. The NVIDIA N1X 48SM has 48 ray tracing cores and 192 tensor cores, giving it 6x the RT cores and a dedicated tensor core array.

Q: What is the process node and die size for each?

A: The AMD chip (Van Gogh) is fabricated on TSMC's 7 nm process with a die size of 163 mm², containing 2,400 million transistors. The NVIDIA chip (GB20B) uses TSMC's 5 nm process with a die size of 382 mm², though its transistor count is listed as unknown in the database.

Where Each One Wins

Based strictly on the recorded specifications, the NVIDIA N1X 48SM wins in nearly every measurable compute category. Its FP32 throughput of 28.83 TFLOPS dwarfs the AMD part's 1.638 TFLOPS, and its texture rate of 900.9 GTexel/s is 17.6x higher than the AMD part's 51.20 GTexel/s. Pixel rate also favors NVIDIA at 112.6 GPixel/s versus 25.60 GPixel/s, a 4.4x margin. Memory capacity and bandwidth are both decisively in NVIDIA's favor: 128 GB versus 16 GB, and 273.2 GB/s versus 102.4 GB/s. The NVIDIA GPU also has a higher boost clock (2346 MHz vs 1600 MHz), more shading units (6144 vs 512), more TMUs (384 vs 32), more ROPs (48 vs 16), more ray tracing cores (48 vs 8), and 192 tensor cores where the AMD part has none.

The AMD Ryzen Z2 A GPU wins in a few narrow areas. Its base clock of 1000 MHz is higher than the NVIDIA part's 741 MHz, which may indicate better low-load efficiency. The AMD part also has the advantage of a smaller die (163 mm² vs 382 mm²) and a lower transistor count (2,400 million vs unknown), suggesting a more compact implementation. The AMD GPU's TDP is listed as 15 W, while the NVIDIA part's TDP is unknown, so no direct power comparison can be made. The AMD part also supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the NVIDIA part lists N/A for all three APIs, meaning the AMD GPU has documented driver-level API support in the database.

Specification Differences

The two GPUs differ across nearly all recorded fields. The AMD Ryzen Z2 A GPU uses the Van Gogh chip with RDNA 2.0 architecture, while the NVIDIA N1X 48SM uses the GB20B chip with Blackwell 2.0 architecture. Process nodes differ: AMD is on 7 nm, NVIDIA on 5 nm. Die size is 163 mm² for AMD versus 382 mm² for NVIDIA, with AMD's transistor density at 14.7M per mm² and NVIDIA's density not recorded.

Clock speeds differ substantially. AMD's base is 1000 MHz with a 1600 MHz boost; NVIDIA's base is 741 MHz with a 2346 MHz boost. Memory clocks also differ: AMD runs at 800 MHz (6.4 Gbps effective), NVIDIA at 1067 MHz (8.5 Gbps effective). Memory configuration is starkly different: 16 GB LPDDR5 on a 128-bit bus versus 128 GB LPDDR5X on a 256-bit bus. Bandwidth is 102.4 GB/s for AMD versus 273.2 GB/s for NVIDIA.

Compute resources are heavily skewed toward NVIDIA. Shading units: 512 vs 6144. TMUs: 32 vs 384. ROPs: 16 vs 48. RT cores: 8 vs 48. Tensor cores: none vs 192. Pixel rate: 25.60 GPixel/s vs 112.6 GPixel/s. Texture rate: 51.20 GTexel/s vs 900.9 GTexel/s. FP32: 1.638 TFLOPS vs 28.83 TFLOPS. FP16: 3.277 TFLOPS (2:1) for AMD versus 28.83 TFLOPS (1:1) for NVIDIA.

Other differences include TDP (15 W for AMD, unknown for NVIDIA), slot width (not listed for AMD, IGP for NVIDIA), power connectors (not listed for AMD, None for NVIDIA), bus interface (not listed for AMD, PCIe 5.0 x16 for NVIDIA), and display outputs (1x USB Type-C for AMD, 1x HDMI for NVIDIA). API support differs: AMD lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while NVIDIA lists N/A for all three. Release dates also differ: AMD was released in December 2024, NVIDIA in May 2026.

Architecture Differences

The architectural split is fundamental. AMD's Van Gogh chip uses RDNA 2.0, a graphics architecture designed for console-class GPUs, and the part is classified under "Console GPU (AMD)". NVIDIA's GB20B chip uses Blackwell 2.0, a newer architecture, and the part is classified under "Blackwell IGP (N1x)". The NVIDIA GPU is an integrated graphics processor (IGP) as indicated by its slot width being "IGP" and its lack of power connectors, whereas the AMD part's slot width is not recorded.

The compute architecture differs in tensor core support. NVIDIA includes 192 tensor cores, enabling dedicated tensor operations, while AMD has none. Ray tracing core counts also differ: 8 for AMD versus 48 for NVIDIA, a 6x advantage for the latter. The FP16 implementation differs: AMD achieves 3.277 TFLOPS at a 2:1 ratio relative to FP32, meaning it halves throughput for FP16, while NVIDIA achieves 28.83 TFLOPS at a 1:1 ratio, indicating full-rate FP16 execution.

Memory architecture differences extend beyond capacity and bandwidth. AMD uses LPDDR5, while NVIDIA uses LPDDR5X, a faster memory type. The bus width is 128-bit for AMD versus 256-bit for NVIDIA, which directly contributes to the bandwidth gap. The NVIDIA part's PCIe 5.0 x16 bus interface is recorded, while AMD's bus interface is not listed. Display outputs also differ: AMD has a single USB Type-C port, NVIDIA has a single HDMI port.

The production status for both parts is "Active", and neither has a listed predecessor or successor in the database. Transistor counts are 2,400 million for AMD and unknown for NVIDIA. The database does not record a launch MSRP for either part, and no power connector or suggested PSU information is available for either.

The Verdict

The data indicates a clear hierarchy: the NVIDIA N1X 48SM is a far more capable compute device on paper. Its FP32 throughput of 28.83 TFLOPS is 17.6x higher than the AMD part's 1.638 TFLOPS. Its texture rate of 900.9 GTexel/s and pixel rate of 112.6 GPixel/s exceed the AMD part's 51.20 GTexel/s and 25.60 GPixel/s by similarly large margins. The memory subsystem is also decisively in NVIDIA's favor, with 128 GB of LPDDR5X versus 16 GB of LPDDR5, and 273.2 GB/s versus 102.4 GB/s of bandwidth. The NVIDIA GPU also carries 192 tensor cores, a feature the AMD part lacks entirely.

However, the AMD Ryzen Z2 A GPU is not without its own strengths. Its 15 W TDP suggests a low-power design, and its smaller die (163 mm²) with a lower transistor count (2,400 million) indicates a more compact and possibly more efficient implementation. The AMD part also has documented API support for DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, whereas the NVIDIA part lists N/A for all of these, which could matter for software compatibility in certain environments.

For users who prioritize raw compute, memory capacity, and bandwidth, the NVIDIA N1X 48SM is the clear choice based on the recorded specifications. For scenarios where low power draw, small die size, and established API support are paramount, the AMD Ryzen Z2 A GPU holds advantages. The database does not include benchmark scores, so the actual performance in real-world workloads cannot be confirmed. The percentile ranking of 50 for both parts suggests they sit at the median of all tracked GPUs, but this figure is not supported by any benchmark data in the record. Ultimately, the choice depends on whether the workload demands the NVIDIA part's massive compute and memory resources or the AMD part's compact, low-power design with full API support.
