AMD Ryzen Z1 GPU vs NVIDIA N1X 40SM Comparison

Where Each One Wins

The recorded data separates these two processors into entirely different performance classes. The AMD Ryzen Z1 GPU is a low-power console-oriented GPU built around a 30 W design envelope, while the NVIDIA N1X 40SM is an integrated graphics processor with a much larger silicon footprint and substantially higher throughput metrics.

In raw compute, the NVIDIA N1X 40SM dominates every measured category. Its FP32 throughput of 24.02 TFLOPS is roughly 9.4 times the AMD Ryzen Z1 GPU's 2.560 TFLOPS. The texture rate follows the same pattern: 750.7 GTexel/s versus 40.00 GTexel/s, an 18.8x gap. Pixel rate shows 93.84 GPixel/s against 20.00 GPixel/s, a 4.7x difference. These are not close contests; the NVIDIA part simply operates in a different tier.

The AMD Ryzen Z1 GPU does hold advantages in specific areas. Its 4 nm process node is smaller than the NVIDIA N1X 40SM's 5 nm node, which suggests better transistor density per square millimeter. The AMD chip packs 25,390 million transistors into a 178 mm² die, yielding a density of 142.6 million transistors per mm². The NVIDIA die is larger at 382 mm², but its transistor count is listed as unknown, so no density comparison can be made from the data.

Power behavior also differs. The AMD Ryzen Z1 GPU has a defined 30 W TDP, while the NVIDIA N1X 40SM's TDP is unknown. The AMD part also carries a 16 GB LPDDR5 memory configuration, whereas the NVIDIA part uses 128 GB of LPDDR5X. For workloads that depend on memory capacity, the NVIDIA part is overwhelmingly larger in that dimension.

The AMD Ryzen Z1 GPU has a launch MSRP of 599 USD, a figure recorded in the database. The NVIDIA N1X 40SM has no recorded launch price.

Architecture Differences

The two chips come from different architectural lineages. The AMD Ryzen Z1 GPU uses RDNA 3.0, built on the Phoenix chip, and belongs to the Console GPU generation. The NVIDIA N1X 40SM uses Blackwell 2.0, built on the GB20B chip, and belongs to the Blackwell IGP generation for N1x.

Process technology separates them: AMD uses a 4 nm node from TSMC, while NVIDIA uses a 5 nm node from the same foundry. The AMD die measures 178 mm² and contains 25,390 million transistors. The NVIDIA die is larger at 382 mm², with transistor count unknown. This makes direct density comparison impossible, but the AMD chip's 142.6 million transistors per mm² is a recorded figure.

Compute resource counts differ sharply. The AMD Ryzen Z1 GPU has 256 shading units, 16 texture mapping units, 8 ROPs, and 4 ray tracing cores. The NVIDIA N1X 40SM has 5,120 shading units, 320 TMUs, 40 ROPs, and 40 RT cores. The NVIDIA part also includes 160 tensor cores; the AMD part's tensor core count is not recorded.

Memory architecture diverges. AMD uses 16 GB of LPDDR5 on a 64-bit bus, producing 51.20 GB/s of bandwidth. NVIDIA uses 128 GB of LPDDR5X on a 256-bit bus, producing 273.2 GB/s. The NVIDIA memory clock runs at 1067 MHz with 8.5 Gbps effective, while the AMD memory clock is 800 MHz with 6.4 Gbps effective.

FP16 processing reveals a key architectural difference. The AMD Ryzen Z1 GPU delivers 5.120 TFLOPS FP16 at a 2:1 ratio relative to FP32, meaning it halves FP32 throughput for FP16 work. The NVIDIA N1X 40SM delivers 24.02 TFLOPS FP16 at a 1:1 ratio, meaning FP16 and FP32 run at the same rate. This indicates the NVIDIA part is built for workloads that rely heavily on reduced-precision arithmetic, while the AMD part trades FP16 capability for power efficiency.

API support also differs. The AMD Ryzen Z1 GPU supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The NVIDIA N1X 40SM lists N/A for DirectX, OpenGL, and Vulkan, which suggests it is not aimed at the same software ecosystem.

Head-to-Head Benchmarks

The database records no direct head-to-head benchmark entries for these two parts. Both have an average benchmark score of zero and a percentile rank of 50 against all GPUs. No wins are recorded for either side in the head-to-head field.

Without direct benchmark runs, the comparison relies on the specification-derived throughput figures. The largest gap is in texture rate. The NVIDIA N1X 40SM's 750.7 GTexel/s is 18.8 times the AMD Ryzen Z1 GPU's 40.00 GTexel/s. This suggests the NVIDIA part can feed texture-heavy rendering pipelines at a rate the AMD part cannot approach.

FP32 throughput shows the second-largest gap. The NVIDIA part's 24.02 TFLOPS is 9.4 times the AMD part's 2.560 TFLOPS. For general compute workloads, the NVIDIA part has nearly an order of magnitude more raw floating-point capacity.

Pixel rate is closer but still lopsided. The NVIDIA N1X 40SM delivers 93.84 GPixel/s against 20.00 GPixel/s for the AMD Ryzen Z1 GPU, a 4.7x difference. This narrower gap suggests the AMD part's fill rate is less disadvantaged than its compute throughput, though it still trails significantly.

Memory bandwidth shows a 5.3x difference. The NVIDIA part's 273.2 GB/s versus the AMD part's 51.20 GB/s means the NVIDIA part can move data to and from memory far faster, which matters for bandwidth-bound workloads.

The NVIDIA part's shading unit count of 5,120 is exactly 20 times the AMD part's 256. Its RT core count of 40 is 10 times the AMD part's 4. Its texture unit count of 320 is exactly 20 times the AMD part's 16. Its ROP count of 40 is 5 times the AMD part's 8. These ratios are consistent with the throughput gaps.

The Verdict

The data points to two different design goals. The AMD Ryzen Z1 GPU is a compact, low-power part with a 30 W TDP, a 4 nm process, and a 178 mm² die. Its 2.560 TFLOPS FP32 and 51.20 GB/s bandwidth suit it for constrained environments where power draw is the limiting factor. Its higher base and boost clocks, 1500 MHz and 2500 MHz respectively, show it is tuned to extract performance within a small power envelope.

The NVIDIA N1X 40SM is built for scale. Its 5,120 shading units, 320 TMUs, 40 RT cores, and 160 tensor cores give it throughput figures that dwarf the AMD part across every measured metric. The 273.2 GB/s memory bandwidth and 128 GB capacity indicate it is designed for data-heavy workloads rather than power-limited scenarios. Its 382 mm² die and PCIe 5.0 x16 interface confirm this is a high-end integrated processor.

Users who need API compatibility with DirectX 12 Ultimate, OpenGL 4.6, or Vulkan 1.4 should note that only the AMD part supports these interfaces. The NVIDIA part lists N/A for all three, which means software expecting those APIs will not run on it according to the recorded data.

The clock speed comparison is revealing. The AMD part clocks higher in both base and boost, yet delivers a fraction of the throughput. This confirms the NVIDIA part's advantage comes from massive parallelism, not clock speed. A 741 MHz base clock with 5,120 shading units still produces 24.02 TFLOPS, while a 1500 MHz base clock with 256 shading units produces only 2.560 TFLOPS.

The release timeline also matters. The AMD Ryzen Z1 GPU was released on 2023-09-17 with a launch MSRP of 599 USD. The NVIDIA N1X 40SM was released on 2026-05-31 with no recorded price. The NVIDIA part is newer by roughly two and a half years, which aligns with its larger die and more advanced memory subsystem.

For workloads that fit within the AMD part's 30 W envelope and require standard graphics APIs, the Ryzen Z1 GPU is the only option with recorded software support. For workloads that need raw throughput, massive memory capacity, or tensor core acceleration, the NVIDIA N1X 40SM is the clear choice based on every measured specification. The 9.4x FP32 gap and 18.8x texture rate gap leave little ambiguity about which part delivers more compute, while the 30 W TDP and 4 nm process make the AMD part the efficiency-focused alternative.
