Analysis: AMD Ryzen Z1 GPU vs NVIDIA N1 20SM

Head-to-Head Benchmarks

The database contains no recorded head-to-head benchmark results for the AMD Ryzen Z1 GPU and the NVIDIA N1 20SM. Both entries show an average benchmark score of zero, and neither has any listed nearest rivals. The percentile versus all GPUs is identical for both at 50, placing them at the median of the recorded distribution despite their very different specifications. Without measured performance data, the comparison must rest entirely on the architectural and specification fields provided.

The absence of benchmark scores is significant in itself. It means no direct frame-rate, compute, or synthetic workload comparisons exist in the database at this time. The AMD Ryzen Z1 GPU carries a release date of September 2023, while the NVIDIA N1 20SM is dated for May 2026, a gap that may explain the lack of overlapping test data. The data shows two products at very different points in their lifecycles, with the NVIDIA part still nearly two years from its listed release at the time of this analysis.

What can be quantified from the recorded fields is the theoretical peak throughput. The NVIDIA N1 20SM delivers 12.01 TFLOPS of FP32 compute, which is roughly 4.7 times the 2.560 TFLOPS of the AMD Ryzen Z1 GPU. The FP16 figures widen the gap further in NVIDIA's favor: the N1 20SM sustains 12.01 TFLOPS with a 1:1 ratio, while the AMD part reaches 5.120 TFLOPS only through a 2:1 ratio, meaning half the rate for true FP16 workloads. Pixel throughput favors NVIDIA at 56.30 GPixel/s versus 20.00 GPixel/s, a 2.8x advantage. Texture rate shows the largest proportional difference, with NVIDIA at 375.4 GTexel/s compared to AMD's 40.00 GTexel/s, a 9.4x margin.

Memory bandwidth tells a similar story. The NVIDIA N1 20SM accesses 273.2 GB/s across a 256-bit LPDDR5X bus, while the AMD Ryzen Z1 GPU manages 51.20 GB/s over a 64-bit LPDDR5 interface. That is a 5.3x bandwidth advantage. These are theoretical figures, not measured results, but they establish the performance envelope each part occupies.

Architecture Differences

The two GPUs come from different architectural generations and design philosophies. The AMD Ryzen Z1 GPU uses the Phoenix chip built on RDNA 3.0 architecture, fabricated on a 4 nm process at TSMC. The NVIDIA N1 20SM uses the GB20B chip with Blackwell 2.0 architecture, also built at TSMC but on a 5 nm node. The process difference is notable: AMD's 4 nm node is smaller, yet the AMD die measures 178 mm² with 25,390 million transistors, producing a density of 142.6 million transistors per square millimeter. The NVIDIA die is larger at 382 mm², but the transistor count is listed as unknown, so density cannot be computed.

The AMD part is categorized as a Console GPU, while the NVIDIA part falls under Blackwell IGP, meaning integrated graphics processor. This distinction appears in the slot width field, where NVIDIA lists "IGP" and AMD leaves the field empty. The NVIDIA chip uses a PCIe 5.0 x16 bus interface, while the AMD entry has no bus interface recorded. Display outputs differ: the NVIDIA N1 20SM provides 1x HDMI, while the AMD Ryzen Z1 GPU lists "No outputs." Power connectors are listed as "None" for both, and the AMD TDP is recorded at 30 W, while the NVIDIA TDP is unknown.

Ray tracing and tensor hardware separate the two clearly. The NVIDIA N1 20SM includes 20 RT cores and 80 tensor cores, while the AMD part has 4 RT cores and no tensor cores listed. The shading unit count favors NVIDIA heavily: 2560 shading units versus 256 for AMD. Texture mapping units number 160 against 16, and render output units stand at 24 versus 8. These are structural differences that reflect the NVIDIA part's larger die and more recent architecture.

API support also diverges. The AMD Ryzen Z1 GPU lists DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1 20SM records "N/A" for DirectX, OpenGL, and Vulkan. This likely reflects the IGP classification and the absence of a conventional driver stack in the database, not an inherent inability to render graphics. The AMD part's API list indicates a full consumer-facing feature set, while the NVIDIA entry's fields are simply unpopulated.

Where Each One Wins

Based on the recorded specification data, the NVIDIA N1 20SM wins on nearly every measurable compute and memory metric. Its FP32 throughput of 12.01 TFLOPS exceeds the AMD part's 2.560 TFLOPS by a factor of 4.7. Texture rate is 9.4x higher, pixel rate is 2.8x higher, and memory bandwidth is 5.3x higher. The NVIDIA part also carries 10x the shading units, 10x the TMUs, and 3x the ROPs. For any workload that scales with raw compute, texture fill, or memory bandwidth, the NVIDIA N1 20SM is the clear choice from the data.

The AMD Ryzen Z1 GPU wins on clock speed. Its base clock of 1500 MHz and boost clock of 2500 MHz both exceed the NVIDIA part's 741 MHz base and 2346 MHz boost. Higher clocks do not translate to higher throughput given the massive core count difference, but they indicate a more power-efficient design per clock. The AMD TDP of 30 W is recorded, while the NVIDIA TDP is unknown, so no direct power comparison is possible. The AMD part also uses a smaller 4 nm process, which typically allows higher clocks at lower power, and its memory runs at 800 MHz with 6.4 Gbps effective, versus the NVIDIA part's 1067 MHz and 8.5 Gbps effective.

The AMD Ryzen Z1 GPU has a fully populated API list (DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4), which suggests it is ready for direct consumer graphics workloads. The NVIDIA part's API fields are all "N/A," which may limit its applicability in conventional gaming or workstation contexts until drivers are established. The AMD part also has a launch MSRP of 599 USD, while the NVIDIA part has no recorded MSRP.

The Verdict

The data points to a clear performance hierarchy. The NVIDIA N1 20SM dominates the AMD Ryzen Z1 GPU across compute throughput, memory bandwidth, texture fill, pixel rate, and core counts. Its 12.01 TFLOPS FP32 figure, 273.2 GB/s bandwidth, and 2560 shading units place it in a different performance class entirely. For any workload that leverages raw shader compute, high-resolution texturing, or large memory pools, the NVIDIA part is the only choice supported by the recorded specifications.

The AMD Ryzen Z1 GPU retains advantages in clock speed and process node. Its 2500 MHz boost clock and 4 nm fabrication suggest a more power-efficient design per clock, and its 30 W TDP is the only power figure recorded for either part. The AMD part also has a complete consumer API stack, with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 all listed. The NVIDIA part's API fields are all "N/A," which may indicate limited software readiness despite its hardware capabilities.

The release dates matter for context. The AMD Ryzen Z1 GPU launched in September 2023 with a 599 USD MSRP. The NVIDIA N1 20SM is dated for May 2026, with no MSRP recorded. The NVIDIA part's 128 GB memory capacity and 256-bit bus suggest a design aimed at integrated AI or data-centric workloads, while the AMD part's 16 GB capacity and 64-bit bus point toward a more constrained console-oriented role.

Users requiring immediate consumer graphics support should consider the AMD Ryzen Z1 GPU, given its populated API list and existing release status. Users prioritizing maximum theoretical performance, memory capacity, and bandwidth should look to the NVIDIA N1 20SM, provided its "N/A" API entries resolve in practice. The absence of benchmark scores means final judgment rests on specification comparison alone, and that comparison favors NVIDIA by wide margins in most categories.
