NVIDIA N1X 40SM vs NVIDIA RTX 5000 Max-Q Ada Generation Comparison

The NVIDIA N1X 40SM and the NVIDIA RTX 5000 Max-Q Ada Generation are two very different mobile processors from the same manufacturer, and the recorded database specifications show a clear separation in their design goals. The N1X 40SM is an integrated graphics processor built on the Blackwell 2.0 architecture, while the RTX 5000 Max-Q is a discrete-class solution based on Ada Lovelace. Although the benchmark result arrays are empty, the technical data in the database provides a basis for comparing their theoretical peak performance, memory subsystem, and feature sets.

Head-to-Head Benchmarks

The database contains no recorded benchmark scores for either processor, so direct performance measurements are unavailable. However, the specification data allows for a computed comparison of raw throughput limits. The RTX 5000 Max-Q Ada Generation delivers a significantly higher FP32 compute rate, rated at 32.69 TFLOPS, compared to the N1X 40SM’s 24.02 TFLOPS. This represents a 36% advantage for the Ada part in single-precision floating-point operations, which is a critical metric for general compute workloads and many graphics shaders.

The gap narrows when examining texture processing. The N1X 40SM achieves a texture rate of 750.7 GTexel/s, while the RTX 5000 Max-Q is rated at 510.7 GTexel/s. The N1X 40SM leads by 47% in this category, a result of its higher TMU count (320 vs. 304) and its significantly higher boost clock of 2346 MHz versus 1680 MHz. In pixel throughput, the RTX 5000 Max-Q reverses the trend, delivering 188.2 GPixel/s against the N1X 40SM’s 93.84 GPixel/s, a 100% advantage. The Ada part’s 112 ROPs versus 40 ROPs explain this substantial difference.

Memory bandwidth presents another clear split. The RTX 5000 Max-Q uses 16 GB of GDDR6 on a 256-bit bus, achieving 576.0 GB/s. The N1X 40SM uses 128 GB of LPDDR5X on the same 256-bit bus width, but its memory clock is much lower, resulting in 273.2 GB/s. The Ada part’s bandwidth is 111% higher, which is crucial for memory-intensive tasks such as high-resolution texturing and large dataset processing. The N1X 40SM’s memory capacity is eight times larger, though the effective data rate is far lower.

For ray tracing and tensor operations, the RTX 5000 Max-Q has 76 RT cores and 304 tensor cores, while the N1X 40SM has 40 RT cores and 160 tensor cores. The Ada part’s core counts are 90% higher for both types, suggesting a proportional advantage in ray-traced rendering and AI acceleration workloads, assuming similar per-core efficiency. The FP16 rates mirror the FP32 rates exactly for both parts (1:1 ratio), with the RTX 5000 Max-Q at 32.69 TFLOPS and the N1X 40SM at 24.02 TFLOPS.

Architecture Differences

The two processors are built on different architectures and target distinct integration levels. The N1X 40SM uses the Blackwell 2.0 architecture and is classified as an IGP (integrated graphics processor), part of the Blackwell IGP (N1x) generation. It is based on the GB20B chip and fabricated on a 5 nm process at TSMC. The die size is 382 mm², and transistor count is listed as unknown. Its clock profile starts at a 741 MHz base and boosts to 2346 MHz, which is a relatively high boost for an integrated solution.

The RTX 5000 Max-Q Ada Generation uses the Ada Lovelace architecture, built on the AD103 chip, also on a 5 nm TSMC process. The die size is 379 mm², slightly smaller than the N1X 40SM, and the transistor count is 45,900 million, giving a density of 121.1M transistors per mm². The base clock is 930 MHz, higher than the N1X 40SM’s base, but the boost clock is lower at 1680 MHz. This difference in clock behavior suggests a different power and thermal envelope, though the N1X 40SM’s TDP is listed as unknown while the RTX 5000 Max-Q is rated at 120 W.

Memory technology is a major architectural differentiator. The N1X 40SM uses LPDDR5X, which is typically soldered and shared with the host system, while the RTX 5000 Max-Q uses dedicated GDDR6. The N1X 40SM’s memory runs at 1067 MHz (8.5 Gbps effective), whereas the RTX 5000 Max-Q’s GDDR6 runs at 2250 MHz (18 Gbps effective). This clock difference, combined with the same 256-bit bus width, produces the large bandwidth disparity. The N1X 40SM’s 128 GB capacity is unusual for an IGP and likely targets specific workloads requiring large in-memory datasets, while the 16 GB on the RTX 5000 Max-Q is more typical for a professional mobile GPU.

The API support also differs. The N1X 40SM lists DirectX, OpenGL, and Vulkan as N/A, indicating that it may not expose traditional graphics APIs or that it relies on a different software path. The RTX 5000 Max-Q supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, providing full compatibility with current graphics and compute frameworks. The bus interface differs as well: the N1X 40SM uses PCIe 5.0 x16, while the RTX 5000 Max-Q uses PCIe 4.0 x16. Both are classified as IGP in slot width, and both have no power connectors listed, with the RTX 5000 Max-Q being a Max-Q design, which typically implies lower power operation.

The N1X 40SM has 5120 shading units, 320 TMUs, and 40 ROPs. The RTX 5000 Max-Q has 9728 shading units, 304 TMUs, and 112 ROPs. The shading unit count is 90% higher on the Ada part, while the ROP count is 180% higher. The N1X 40SM’s higher TMU count and boost clock allow it to lead in texture fill rate despite fewer shaders. The RTX 5000 Max-Q’s release date is recorded as 2023-03-20, while the N1X 40SM’s release date is 2026-05-31, suggesting a newer design for the Blackwell part.

Where Each One Wins

The N1X 40SM demonstrates advantages in specific areas based on its specification profile. Its texture rate of 750.7 GTexel/s is superior, which means workloads that rely heavily on texture sampling, such as certain types of terrain rendering or procedural texture generation, could benefit from this part. The large 128 GB memory capacity is a unique asset; for applications that need to hold massive datasets in memory without swapping, such as large language model inference or in-memory databases, the N1X 40SM provides a capacity that the RTX 5000 Max-Q cannot match. The higher boost clock of 2346 MHz also suggests better performance in bursty, clock-limited scenarios, though the overall FP32 throughput remains lower.

The RTX 5000 Max-Q Ada Generation wins in raw compute and memory bandwidth. Its FP32 rate of 32.69 TFLOPS is 36% higher, making it the stronger choice for general-purpose GPU compute, scientific simulations, and rendering workloads that are shader-bound. The memory bandwidth of 576.0 GB/s is more than double that of the N1X 40SM, which is critical for high-resolution textures, large framebuffers, and data-intensive compute kernels. The pixel rate of 188.2 GPixel/s is double the N1X 40SM’s, giving it a clear edge in fill-rate-limited scenarios such as high-resolution rasterization and post-processing effects.

The RTX 5000 Max-Q also has the advantage in API compatibility. With DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, it can run standard graphics applications and games directly. The N1X 40SM’s API support is listed as N/A, which could limit its use in conventional gaming or workstation graphics environments, potentially restricting it to a specialized compute or display role. The Ada part’s higher RT core and tensor core counts (76 vs. 40, and 304 vs. 160) indicate a stronger position for ray-traced rendering and AI inference tasks, even without direct benchmark data.

For memory capacity, the N1X 40SM is the clear winner with 128 GB versus 16 GB. For memory speed, the RTX 5000 Max-Q is the winner with 576.0 GB/s versus 273.2 GB/s. The choice between these two depends on whether the workload prioritizes capacity over bandwidth. The N1X 40SM’s PCIe 5.0 x16 interface provides higher interconnect bandwidth potential compared to the RTX 5000 Max-Q’s PCIe 4.0 x16, which could benefit workflows that transfer data between the GPU and host frequently.
