NVIDIA N1X 48SM

Benchmark Performance

The NVIDIA N1X 48SM presents a unique benchmark profile. With an average benchmark score of 0 and a percentile ranking of 50 against all GPUs, the data indicates this part sits at the exact median of the database's tested hardware. However, the absence of any individual benchmark entries and a zero average score suggest that the performance data is either preliminary, derived from a limited sample, or represents a baseline reference point rather than a collection of traditional gaming or compute workloads. The FP32 compute throughput is listed at 28.83 TFLOPS, which is a substantial figure for a 6144-shading-unit configuration. The FP16 performance matches this exactly at 28.83 TFLOPS with a 1:1 ratio, indicating a deliberate design choice to prioritize raw single-precision and half-precision compute over specialized rate increases.

The pixel fill rate of 112.6 GPixel/s, derived from the 48 ROPs and the 2346 MHz boost clock, places the rasterization throughput at a level that is modest relative to the compute capability. Conversely, the texture rate of 900.9 GTexel/s, calculated from 384 TMUs, is exceptionally high, suggesting the architecture is heavily optimized for texture fetch and filtering workloads. The data reveals a significant imbalance: the shading and texture engines are vastly more powerful than the pixel output stage. This is a common trait in compute-oriented or AI-accelerator silicon rather than traditional gaming GPUs, meaning the raw numbers will translate to different real-world performance depending on the workload type. For workloads that stress pixel throughput, the 112.6 GPixel/s figure will be the limiting factor. For shader-bound or texture-bound tasks, the 28.83 TFLOPS and 900.9 GTexel/s figures will dominate the performance narrative.

The boost clock of 2346 MHz is the highest operational frequency listed, with a base clock of 741 MHz. The wide delta between base and boost clocks indicates a power-management strategy that allows for aggressive boosting under load when thermal and power headroom permit, but also a very low idle or baseline state. The memory clock is listed at 1067 MHz, resulting in 8.5 Gbps effective data rate. The effective bandwidth is computed as 273.2 GB/s, which will be analyzed further in the memory subsystem section. Given the lack of benchmark entries and the zero average score, any comparison to specific rival products is not possible from the provided data. The percentile rank of 50 implies that half of all GPUs in the database score higher and half score lower, but the zero score itself prevents a definitive statement on where this part lands in terms of absolute performance tiers.

How It Compares

The `nearestRivals` array is empty in the FACT PACK. Consequently, there are no specific rival names, scores, or deltaPct values to reference for direct comparison. The data provides a percentile ranking against all GPUs, which places the N1X 48SM at the 50th percentile. This indicates a median position in the overall performance distribution of the database, but without specific rival entries, a granular comparison is impossible. The benchmark results indicate that while the compute specifications are high, the lack of direct rivals in the dataset means the performance positioning is defined solely by this median percentile. The absence of deltaPct values also means there is no quantitative percentage lead or deficit to cite for any other product. The data shows the part is active in production, but its competitive standing relative to named products remains undefined in this dataset.

Who Should Consider It

Based on the benchmark results, the N1X 48SM is a complex recommendation. The 28.83 TFLOPS FP32 performance is indicative of high compute capability, suitable for tasks that leverage massive parallel processing, such as scientific simulation, AI inference, or rendering workloads that are not pixel-bound. The 1:1 FP16 ratio means that half-precision workloads will see no speedup over single-precision, which is a common optimization for AI inference where FP16 is often utilized; however, the lack of a doubled rate suggests the architecture prioritizes consistent throughput across precisions rather than specialized acceleration. The 112.6 GPixel/s pixel rate, however, suggests that for traditional 1080p or 1440p gaming at high frame rates, the rasterization pipeline will be a bottleneck. The high texture rate of 900.9 GTexel/s will help in resolution scaling for texture detail, but the pixel output will cap the final frame rate.

The data suggests that users who prioritize compute-heavy tasks, such as machine learning model training or inference, will find the 28.83 TFLOPS figure compelling. For gaming, the pixel rate is the limiting factor; the part may be better suited for lower resolutions or less demanding graphical settings where pixel throughput is not the primary constraint. The 128 GB memory capacity, coupled with the 273.2 GB/s bandwidth, makes this a candidate for large dataset processing that fits within the VRAM, but the bandwidth is not exceptionally high for the capacity. Users with workloads that are memory-capacity bound rather than bandwidth bound would benefit most. The 50th percentile rank suggests it is an average performer in the overall database, so it is not positioned as a top-tier part. The zero average benchmark score complicates this further, as it implies no single workload has been recorded to establish a performance baseline.

Power and Cooling

The FACT PACK does not include a TDP (Thermal Design Power) value, leaving the power consumption figure unknown. Consequently, there is no suggested PSU (Power Supply Unit) recommendation provided in the data. The slot width is listed as "IGP" (Integrated Graphics Processor), which indicates this is not a discrete expansion card but rather an integrated solution. The power connectors field is listed as "None," which aligns with the IGP designation; integrated processors typically draw power from the motherboard socket rather than requiring dedicated PCIe power cables. The absence of a TDP figure means that thermal solution requirements cannot be quantified, but the data shows a base clock of 741 MHz and a boost clock of 2346 MHz, which implies a wide dynamic power range during operation. The production status is "Active," and the part uses a 5 nm process node from TSMC, which typically contributes to power efficiency, but without a wattage figure, any efficiency claims are qualitative. The bus interface is PCIe 5.0 x16, which is the sole connection to the system, providing both data and power delivery for an IGP. The lack of a PSU recommendation in the data suggests that system power requirements are determined by the host platform rather than a discrete add-in card.

Memory Subsystem

The memory subsystem is a defining feature of the NVIDIA N1X 48SM. It is equipped with 128 GB of LPDDR5X memory, a substantial capacity that far exceeds typical consumer GPU memory allocations. The memory type is LPDDR5X, which is a low-power DRAM standard often used in mobile and integrated contexts. The bus width is 256 bits, and the memory clock is 1067 MHz, with an effective data rate of 8.5 Gbps. The resulting memory bandwidth is 273.2 GB/s. The effective data rate of 8.5 Gbps is achieved through the memory clock of 1067 MHz, which is a relatively low clock speed for a 256-bit bus, but the LPDDR5X type compensates with high data transfer rates per pin.

With 128 GB at a 256-bit bus width, the memory is organized as a large pool with moderate bandwidth. For high-resolution workloads, such as 4K or 8K rendering, the capacity is more than sufficient to hold large textures, frame buffers, and datasets. However, the 273.2 GB/s bandwidth is a limiting factor for high-resolution gaming at high frame rates, where the GPU must access textures and geometry quickly. The bandwidth is sufficient for compute workloads that are capacity-bound, meaning they require large amounts of data to be resident but do not access it at extreme rates. The 48 ROPs and the pixel rate of 112.6 GPixel/s will interact with the memory bandwidth; at 4K resolutions, the pixel rate may be reached before the bandwidth is saturated, or vice versa, depending on the specific scene complexity. For 1080p and 1440p, the bandwidth is likely adequate for most workloads, but the pixel rate will be the primary bottleneck. The 128 GB capacity is a unique selling point; it is positioned for AI training or inference on large models that require massive memory residency, but the bandwidth is not designed to feed the 28.83 TFLOPS compute rate at full efficiency in all scenarios.

Ray Tracing and Feature Set

The NVIDIA N1X 48SM is equipped with dedicated ray tracing and tensor cores. It has 48 RT cores and 192 tensor cores. The RT core count matches the number of shading units divided by 128 (6144 / 128 = 48), indicating a consistent ratio of ray tracing hardware per shader partition. The tensor core count of 192 is a separate count. The FP32 performance of 28.83 TFLOPS, when combined with the tensor cores, suggests a capability for AI-accelerated features, though the specific tensor core throughput (e.g., TOPS) is not listed in the FACT PACK. The architecture is Blackwell 2.0, built on the GB20B chip, which is a 5 nm part from TSMC. The API support is listed as "N/A" for DirectX, OpenGL, and Vulkan. This is a critical data point: it indicates that the standard graphics APIs are either not supported or not applicable for this part. The display outputs are limited to 1x HDMI, which is minimal.

The presence of RT cores and tensor cores, combined with the "N/A" API support, paints a picture of a compute-focused accelerator rather than a consumer graphics card. The ray tracing cores exist, but without DirectX or Vulkan support, traditional DXR or Vulkan RT game workloads are not possible. The 48 RT cores will be idle in standard gaming contexts. The 192 tensor cores are likely the primary compute engines, given the 1:1 FP16 ratio and the 28.83 TFLOPS figure, which is often associated with matrix math operations. The architecture name, Blackwell 2.0, and the generation "Blackwell IGP (N1x)" confirm this is an integrated graphics processor. The lack of standard API support means that any software must interface directly with the hardware via CUDA or similar proprietary compute stacks, rather than through graphics APIs. The 1x HDMI output suggests a minimal display capability, primarily for debug or basic output, not for multi-monitor gaming or content creation. The feature set is therefore specialized: RT and tensor cores are present, but the software ecosystem is limited to compute workloads that bypass traditional graphics APIs.
