NVIDIA N1X 40SM vs NVIDIA RTX 4500 Ada Generation Comparison

Head-to-Head Benchmarks

The recorded data contains no direct head-to-head benchmark results between the NVIDIA N1X 40SM and the NVIDIA RTX 4500 Ada Generation. The database shows zero wins for either part in direct comparison tests, and no shared workload scores exist for both products. This absence of overlapping measurements means a conventional win-loss breakdown is not possible from the available records.

Instead, the comparative picture must be assembled from the standalone benchmark data recorded for the RTX 4500 Ada Generation and from the broader positioning of the N1X 40SM within the database. The RTX 4500 Ada Generation has two recorded scores: 160,786 in geekbench_opencl and 171,401 in geekbench_vulkan. Its average benchmark score across all recorded tests is 166,094. The N1X 40SM has no benchmark scores recorded at all, and its average benchmark score is listed as zero.

The RTX 4500 Ada Generation sits at the 97th percentile among all GPUs in the database, a position that places it among the highest-performing workstation parts tracked. Its nearest rivals in the database include the NVIDIA RTX A5500 with an average score of 165,217 (the RTX 4500 leads by 0.5%), the AMD Radeon PRO W7800 at 164,894 (a 0.7% lead), the AMD Radeon Pro W6900X at 168,574 (a 1.5% deficit), and the NVIDIA A100 PCIe 40 GB at 162,504 (a 2.2% lead). These margins are narrow, indicating that the RTX 4500 Ada Generation trades places with its closest competitors rather than dominating them.

The N1X 40SM, by contrast, is listed at the 50th percentile among all GPUs, with no rival comparisons captured in the database. Its percentile rank implies a mid-pack position, but without benchmark scores, the database provides no quantitative basis for asserting how it would perform against the RTX 4500 Ada Generation in any specific workload.

What the data does support is a clear separation in compute capability. The RTX 4500 Ada Generation delivers 39.63 TFLOPS of FP32 performance and the same figure for FP16. The N1X 40SM delivers 24.02 TFLOPS for both FP32 and FP16. That is a 65% advantage for the RTX 4500 Ada Generation in raw floating-point throughput, a substantial gap that would likely translate into significant differences in compute-heavy applications.

Pixel and texture throughput tell a mixed story. The RTX 4500 Ada Generation reaches 206.4 GPixel/s and 619.2 GTexel/s. The N1X 40SM reaches 93.84 GPixel/s and 750.7 GTexel/s. The RTX 4500 leads pixel fill by a factor of 2.2, while the N1X 40SM leads texture fill by 21%. These divergent strengths reflect different architectural priorities, with the N1X 40SM packing more texture units relative to its shading core count.

Memory bandwidth favors the RTX 4500 Ada Generation at 432.0 GB/s versus 273.2 GB/s for the N1X 40SM, a 58% advantage. However, memory capacity strongly favors the N1X 40SM at 128 GB versus 24 GB, a fivefold difference. The N1X 40SM uses LPDDR5X memory on a 256-bit bus, while the RTX 4500 Ada Generation uses GDDR6 on a 192-bit bus.

Architecture Differences

The two GPUs come from different NVIDIA architecture families. The N1X 40SM uses the GB20B chip built on the Blackwell 2.0 architecture, part of the Blackwell IGP (N1x) generation. The RTX 4500 Ada Generation uses the AD103 chip built on the Ada Lovelace architecture, part of the Workstation Ada generation.

Both are fabricated on a 5 nm process at TSMC. The die sizes are nearly identical: 382 mm² for the N1X 40SM and 379 mm² for the RTX 4500 Ada Generation. Transistor counts differ sharply, however. The RTX 4500 Ada Generation contains 45,900 million transistors with a density of 121.1M per mm². The N1X 40SM's transistor count is listed as unknown, so no density figure can be derived.

The N1X 40SM is an integrated graphics processor (IGP) with no slot width, no power connectors, and a single HDMI display output. The RTX 4500 Ada Generation is a dual-slot discrete card measuring 245 mm in length and 112 mm in height, with four DisplayPort 1.4a outputs.

The N1X 40SM uses a PCIe 5.0 x16 bus interface, while the RTX 4500 Ada Generation uses PCIe 4.0 x16. The N1X 40SM is the newer part, with a release date of May 31, 2026, versus August 8, 2023, for the RTX 4500 Ada Generation.

The RTX 4500 Ada Generation has a known predecessor and successor: Workstation Ampere and Blackwell PRO W, respectively. The N1X 40SM lists neither a predecessor nor a successor. Both parts are currently marked as active in production.

The N1X 40SM reports no API support in the database, with DirectX, OpenGL, and Vulkan all listed as N/A. The RTX 4500 Ada Generation supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

Specification Differences

The RTX 4500 Ada Generation carries more shading units: 7,680 versus 5,120 for the N1X 40SM. It also has more RT cores at 60 versus 40, and more tensor cores at 240 versus 160. The N1X 40SM has more texture mapping units at 320 versus 240, while the RTX 4500 Ada Generation has more ROPs at 80 versus 40.

Clock speeds differ substantially. The RTX 4500 Ada Generation runs at a base clock of 2070 MHz and a boost clock of 2580 MHz. The N1X 40SM runs at a base clock of 741 MHz and a boost clock of 2346 MHz.

The N1X 40SM has a 50th percentile ranking among all GPUs, while the RTX 4500 Ada Generation is at the 97th percentile. The RTX 4500 Ada Generation has an average benchmark score of 166,094, while the N1X 40SM has an average benchmark score of zero.

Where Each One Wins

The RTX 4500 Ada Generation wins decisively in compute throughput. Its 39.63 TFLOPS of FP32 and FP16 performance versus 24.02 TFLOPS for the N1X 40SM gives it a 65% edge in raw mathematical throughput. This advantage extends to pixel processing, where the RTX 4500 Ada Generation's 206.4 GPixel/s more than doubles the N1X 40SM's 93.84 GPixel/s. The RTX 4500 Ada Generation also holds a 58% memory bandwidth advantage at 432.0 GB/s versus 273.2 GB/s. Its 97th percentile ranking, benchmark scores above 160,000 in both OpenCL and Vulkan, and narrow margins against high-end rivals such as the RTX A5500 and AMD Radeon PRO W7800 all indicate that this is a capable workstation part for compute-heavy and graphics-intensive workloads.

The N1X 40SM wins in areas that suit a large-memory IGP. Its 128 GB of LPDDR5X memory dwarfs the RTX 4500 Ada Generation's 24 GB, making it the clear choice for workloads that need to hold very large datasets in local memory. Its 320 texture units versus 240 give it a 21% advantage in texture fill rate at 750.7 GTexel/s versus 619.2 GTexel/s. The N1X 40SM also uses a newer PCIe 5.0 x16 interface, which provides higher bandwidth to the host system than the RTX 4500 Ada Generation's PCIe 4.0 x16. Its IGP form factor with no power connectors means it draws power through the motherboard interface, which may suit compact or integrated system designs where a dual-slot discrete card is not an option.

The RTX 4500 Ada Generation is the only one of the two with recorded benchmark data, so its performance profile is empirically established. The N1X 40SM has no recorded scores, so its actual performance in the database is unverified. The RTX 4500 Ada Generation also has a well-defined software ecosystem with DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4 support, while the N1X 40SM lists no API support in the database.

The N1X 40SM is the newer product by release date, launching in 2026 versus 2023 for the RTX 4500 Ada Generation. It also has a larger die by 3 mm². The RTX 4500 Ada Generation has a known successor in the Blackwell PRO W line, while the N1X 40SM has no listed successor. The RTX 4500 Ada Generation is a proven quantity in the database with a high percentile rank and strong benchmark scores, while the N1X 40SM remains an unmeasured entry with only its specifications to define it.
