AMD Ryzen Z2 A GPU vs NVIDIA N1 20SM Comparison

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the AMD Ryzen Z2 A GPU and the NVIDIA N1 20SM. Both entries have empty benchmark arrays, zero recorded wins, and an average benchmark score of zero. The absence of measured performance data means that a direct numerical comparison of frame rates, compute throughput, or synthetic test scores is not possible from the recorded information.

What can be compared directly is the theoretical peak throughput derived from the specification sheets. The AMD Ryzen Z2 A GPU delivers 1.638 TFLOPS of FP32 compute, while the NVIDIA N1 20SM delivers 12.01 TFLOPS of FP32 compute. This represents a 7.33 times advantage for the NVIDIA part in raw single-precision floating-point throughput. The difference is substantial: the NVIDIA N1 20SM outputs more than seven times the FP32 work per clock cycle across its 2560 shading units compared to the 512 shading units on the AMD chip.

Texture processing shows an even wider gap. The AMD Ryzen Z2 A GPU achieves 51.20 GTexel/s, while the NVIDIA N1 20SM reaches 375.4 GTexel/s. The NVIDIA part processes approximately 7.33 times more texels per second, consistent with its 160 texture mapping units versus the AMD part's 32 TMUs. Pixel throughput tells a similar story: 25.60 GPixel/s for AMD versus 56.30 GPixel/s for NVIDIA, a factor of 2.2 in favor of the NVIDIA N1 20SM despite its smaller ROP count advantage of 24 versus 16.

Memory bandwidth heavily favors the NVIDIA N1 20SM. The AMD Ryzen Z2 A GPU has a 128-bit LPDDR5 interface delivering 102.4 GB/s, while the NVIDIA N1 20SM uses a 256-bit LPDDR5X interface delivering 273.2 GB/s. That is 2.67 times more bandwidth for the NVIDIA part. The memory capacity difference is even more pronounced: 16 GB on the AMD versus 128 GB on the NVIDIA, an eightfold gap. These are the only concrete numeric comparisons available from the database, as neither part has any recorded benchmark scores, rival comparisons, or percentile deltas beyond the identical 50th percentile placement.

Where Each One Wins

Without benchmark results, the win analysis must rest on specification advantages. The AMD Ryzen Z2 A GPU holds wins in several efficiency-oriented categories. Its 15 W TDP is the only confirmed power figure in the database for either part; the NVIDIA N1 20SM lists TDP as unknown. The AMD chip uses a 7 nm process from TSMC, while the NVIDIA part uses a 5 nm process from the same foundry. The AMD die is 163 mm² with 2,400 million transistors, giving a transistor density of 14.7M per mm². The NVIDIA die is 382 mm² with transistor count listed as unknown, so density cannot be calculated for comparison.

The AMD Ryzen Z2 A GPU has a higher base clock at 1000 MHz versus 741 MHz for the NVIDIA part, though the NVIDIA N1 20SM boosts to 2346 MHz versus 1600 MHz for AMD. The AMD part supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1 20SM lists all three APIs as N/A, meaning the recorded data shows no DirectX, OpenGL, or Vulkan support for that chip. This gives the AMD part a clear software compatibility advantage in the database record.

The NVIDIA N1 20SM wins on memory capacity, memory bandwidth, shading units, texture units, ROPs, ray tracing cores, tensor cores, FP32 throughput, FP16 throughput, pixel rate, texture rate, boost clock, and process node. It also uses faster LPDDR5X memory at 8.5 Gbps effective versus the AMD part's LPDDR5 at 6.4 Gbps effective. The NVIDIA part has a PCIe 5.0 x16 bus interface, while the AMD part lists no bus interface in the database. Display outputs differ as well: the AMD chip has 1x USB Type-C, while the NVIDIA chip has 1x HDMI.

Architecture Differences

The AMD Ryzen Z2 A GPU uses the Van Gogh chip based on RDNA 2.0 architecture, classified in the database as a Console GPU. The NVIDIA N1 20SM uses the GB20B chip based on Blackwell 2.0 architecture, classified as a Blackwell IGP. The generational labels differ: AMD is listed under "Console GPU (AMD)" while NVIDIA is under "Blackwell IGP (N1x)". These are fundamentally different product categories, with the AMD part positioned as a console-class integrated solution and the NVIDIA part as an integrated graphics processor for the N1x platform.

Process technology differs by two nodes. The AMD chip is built on TSMC's 7 nm process, while the NVIDIA chip uses TSMC's 5 nm process. The die sizes are 163 mm² for AMD and 382 mm² for NVIDIA. The AMD chip packs 2,400 million transistors at a density of 14.7M per mm². The NVIDIA transistor count is unknown in the database, and no density figure is provided.

Ray tracing hardware differs in count and generation. The AMD RDNA 2.0 part has 8 ray tracing cores, while the NVIDIA Blackwell 2.0 part has 20 ray tracing cores. Tensor core support is exclusive to the NVIDIA part, which lists 80 tensor cores; the AMD part lists none. This indicates the NVIDIA N1 20SM carries dedicated AI acceleration hardware that the AMD part lacks entirely.

Memory architecture diverges sharply. The AMD Ryzen Z2 A GPU uses LPDDR5 with a 128-bit bus and 800 MHz base memory clock (6.4 Gbps effective). The NVIDIA N1 20SM uses LPDDR5X with a 256-bit bus and 1067 MHz base memory clock (8.5 Gbps effective). The NVIDIA memory clock is 1.33 times higher, the bus is twice as wide, and the memory type is faster, resulting in the 273.2 GB/s bandwidth figure versus 102.4 GB/s.

FP16 compute reveals a design philosophy difference. The AMD part lists FP16 at 3.277 TFLOPS with a 2:1 ratio to FP32, meaning it uses packed math to double throughput. The NVIDIA part lists FP16 at 12.01 TFLOPS with a 1:1 ratio, meaning its FP16 throughput matches FP32 exactly. The NVIDIA approach delivers 3.67 times the FP16 throughput of the AMD part, but the AMD part gains a 2x advantage over its own FP32 rate through packing.

The Verdict

The database shows a clear specification hierarchy between these two parts. The NVIDIA N1 20SM dominates every raw performance metric recorded: FP32 throughput, FP16 throughput, texture rate, pixel rate, shading units, memory capacity, memory bandwidth, and ray tracing core count. Its 12.01 TFLOPS FP32 figure is 7.33 times the AMD part's 1.638 TFLOPS. Its 375.4 GTexel/s texture rate is 7.33 times the AMD part's 51.20 GTexel/s. Its 273.2 GB/s memory bandwidth is 2.67 times the AMD part's 102.4 GB/s.

The AMD Ryzen Z2 A GPU holds advantages in areas that matter for certain deployment scenarios. It has a confirmed 15 W TDP, while the NVIDIA part has no TDP recorded. It supports modern graphics APIs including DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4, while the NVIDIA part records no API support. It also has a higher base clock of 1000 MHz versus 741 MHz, though the NVIDIA part's boost clock of 2346 MHz far exceeds the AMD part's 1600 MHz.

The release dates place these products in different eras. The AMD Ryzen Z2 A GPU entered the database with a release date of 2024-12-31, while the NVIDIA N1 20SM has a release date of 2026-05-31. The 5 nm NVIDIA process node is two generations ahead of the 7 nm AMD node. The NVIDIA die is 382 mm² versus 163 mm² for AMD, reflecting the much larger silicon budget dedicated to the NVIDIA part.

The identical 50th percentile ranking for both parts in the database reflects the absence of benchmark data rather than equivalence in capability. Neither part has any nearest rivals recorded, and both have an average benchmark score of zero. Without measured performance results, the database can only present the specification deltas as the basis for selection.

For workloads that depend on raw compute throughput, memory bandwidth, or AI acceleration through tensor cores, the NVIDIA N1 20SM is the only choice supported by the recorded data. Its 80 tensor cores, 20 ray tracing cores, 2560 shading units, and 128 GB of LPDDR5X memory place it in a different performance class entirely. The AMD Ryzen Z2 A GPU with 512 shading units, 8 ray tracing cores, no tensor cores, and 16 GB of memory cannot match these figures.

For deployments that require established graphics API compatibility, the AMD Ryzen Z2 A GPU has the only recorded support. DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 are all listed for the AMD part, while the NVIDIA part lists N/A for all three. The AMD part also has the only confirmed power consumption figure at 15 W, which suggests a lower power envelope, though the NVIDIA TDP is unknown rather than confirmed higher.

The practical guidance from the database is straightforward: the NVIDIA N1 20SM is the superior part on every measured performance specification, while the AMD Ryzen Z2 A GPU offers confirmed API support, a confirmed power draw, and an earlier release date. The choice depends on whether the application requires the NVIDIA part's massive compute and memory advantages or the AMD part's software compatibility and confirmed efficiency profile.
