NVIDIA GeForce RTX 4050 Max-Q vs NVIDIA N1X 40SM Comparison

NVIDIA GeForce RTX 4050 Max-Q and NVIDIA N1X 40SM serve completely different purposes, and the recorded data confirms they should not be viewed as direct competitors. The RTX 4050 Max-Q is an Ada Lovelace mobile GPU designed for thin laptops, while the N1X 40SM is a Blackwell IGP with a massive 128 GB memory pool. This analysis focuses on how their specifications dictate distinct use cases.

Where Each One Wins

The RTX 4050 Max-Q wins in scenarios requiring established software compatibility and efficient power delivery. Its 35 W TDP makes it suitable for portable devices where thermal limits are tight. The N1X 40SM wins in raw throughput and memory capacity, with its 24.02 TFLOPS FP32 performance dwarfing the 8.218 TFLOPS of the RTX 4050 Max-Q. For large dataset handling, the N1X 40SM's 128 GB LPDDR5X memory with 273.2 GB/s bandwidth is in another class compared to the 6 GB GDDR6 with 192.0 GB/s on the RTX 4050 Max-Q.

The RTX 4050 Max-Q has full API support with DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4, while the N1X 40SM reports N/A for all three APIs. This makes the RTX 4050 Max-Q the only option for gaming or traditional graphics workloads. The N1X 40SM instead focuses on compute throughput, with 5120 shading units versus 2560, and 160 tensor cores versus 80.

Architecture Differences

The process nodes are identical at 5 nm from TSMC, but the architectures diverge significantly. The RTX 4050 Max-Q uses the AD107 chip based on Ada Lovelace architecture, with 18,900 million transistors on a 159 mm² die. The N1X 40SM uses the GB20B chip based on Blackwell 2.0 architecture, with an unknown transistor count on a much larger 382 mm² die.

Clock speeds tell different stories. The RTX 4050 Max-Q has a base clock of 1140 MHz and a boost of 1605 MHz. The N1X 40SM runs at a lower base of 741 MHz but boosts much higher to 2346 MHz. This higher boost clock, combined with more execution units, produces the N1X 40SM's substantial performance advantage.

Memory configurations are radically different. The RTX 4050 Max-Q uses 6 GB of GDDR6 on a 96-bit bus, achieving 192.0 GB/s bandwidth. The N1X 40SM uses 128 GB of LPDDR5X on a 256-bit bus, achieving 273.2 GB/s. The memory clock also differs, with the RTX 4050 Max-Q at 2000 MHz (16 Gbps effective) and the N1X 40SM at 1067 MHz (8.5 Gbps effective).

The RTX 4050 Max-Q has 80 TMUs and 48 ROPs, while the N1X 40SM has 320 TMUs and 40 ROPs. The texture rate of the N1X 40SM reaches 750.7 GTexel/s versus 128.4 GTexel/s for the RTX 4050 Max-Q. The pixel rate is closer, with the N1X 40SM at 93.84 GPixel/s and the RTX 4050 Max-Q at 77.04 GPixel/s.

The bus interface differs as well, with the RTX 4050 Max-Q using PCIe 4.0 x8 and the N1X 40SM using PCIe 5.0 x16. Both are IGP slot width with no power connectors, but the RTX 4050 Max-Q specifies a 35 W TDP while the N1X 40SM lists unknown TDP.

Head-to-Head Benchmarks

The FP32 throughput comparison is stark. The N1X 40SM delivers 24.02 TFLOPS, which is approximately 2.9 times the 8.218 TFLOPS of the RTX 4050 Max-Q. This difference indicates the N1X 40SM handles compute-heavy workloads with substantially more headroom.

Memory bandwidth favors the N1X 40SM by 273.2 GB/s versus 192.0 GB/s, a 42% advantage. Combined with 128 GB capacity versus 6 GB, the N1X 40SM can keep far more data resident for processing.

Texture rate shows the largest proportional gap. The N1X 40SM achieves 750.7 GTexel/s, which is 5.8 times the 128.4 GTexel/s of the RTX 4050 Max-Q. The N1X 40SM has 320 TMUs compared to 80, explaining this advantage.

Pixel rate is the closest metric. The N1X 40SM's 93.84 GPixel/s is only 22% above the RTX 4050 Max-Q's 77.04 GPixel/s. The RTX 4050 Max-Q has 48 ROPs versus 40 on the N1X 40SM, partially compensating for the clock and shading unit differences.

Ray tracing cores favor the N1X 40SM with 40 units versus 20 on the RTX 4050 Max-Q. Tensor cores similarly favor the N1X 40SM with 160 versus 80. However, the RTX 4050 Max-Q supports DirectX 12 Ultimate, while the N1X 40SM reports no DirectX support, so these hardware advantages may not translate to gaming workloads.

The RTX 4050 Max-Q has a higher base clock at 1140 MHz versus 741 MHz, but the N1X 40SM's boost clock of 2346 MHz exceeds the 1605 MHz of the RTX 4050 Max-Q. Both support FP16 at 1:1 ratio with FP32.

The Verdict

The data shows two products with almost no overlap in intended function. The RTX 4050 Max-Q is the only choice for gaming or general graphics applications because it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. Its 35 W TDP and IGP form factor fit portable devices, and its 6 GB memory is adequate for mainstream gaming at modest settings.

The N1X 40SM is not a gaming GPU. Its API support is listed as N/A, which means no DirectX, OpenGL, or Vulkan compatibility. Instead, its 24.02 TFLOPS FP32, 5120 shading units, and 128 GB memory point toward compute, AI inference, or large-scale data processing. The PCIe 5.0 x16 interface provides high-bandwidth host connectivity.

Buyers should select the RTX 4050 Max-Q for thin-and-light laptops with gaming capability. The N1X 40SM suits systems where memory capacity and raw compute throughput matter more than graphics API compatibility. Both are active production parts, with the RTX 4050 Max-Q released in 2023 and the N1X 40SM slated for 2026.
