NVIDIA GeForce RTX 4050 Max-Q vs NVIDIA N1 20SM Comparison

Where Each One Wins

The recorded data shows two distinct usage profiles. The NVIDIA GeForce RTX 4050 Max-Q targets conventional graphics workloads with full DirectX 12 Ultimate support and a compact 96-bit memory path. The NVIDIA N1 20SM focuses on high-bandwidth unified memory access and raw compute throughput, but it lacks any DirectX, OpenGL, or Vulkan API support, making it unsuitable for standard gaming or graphics applications.

The RTX 4050 Max-Q wins in ecosystem compatibility and traditional rasterization efficiency. Its 48 ROPs deliver a pixel rate of 77.04 GPixel/s, which is 36.8% higher than the N1 20SM's 56.30 GPixel/s. This advantage matters for fill-rate-bound scenarios such as high-resolution texture writes and framebuffer operations. The Ada Lovelace architecture also provides DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 support, enabling hardware ray tracing and mesh shaders through its 20 RT cores and 80 tensor cores.

The N1 20SM wins in compute throughput and memory capacity. Its FP32 performance reaches 12.01 TFLOPS, which is 46.2% higher than the RTX 4050 Max-Q's 8.218 TFLOPS. Texture rate is another decisive area: 375.4 GTexel/s versus 128.4 GTexel/s, a 192.4% advantage driven by 160 TMUs. The 128 GB LPDDR5X memory pool with 273.2 GB/s bandwidth dwarfs the 6 GB GDDR6 configuration at 192.0 GB/s, making the N1 20SM the clear choice for large in-memory datasets. The N1 20SM also uses a PCIe 5.0 x16 interface versus the RTX 4050 Max-Q's PCIe 4.0 x8, doubling the available host link lanes and generation.

The benchmark database assigns both parts a percentile rank of 50 against all GPUs, with an average benchmark score of 0 for each. This indicates that neither has recorded standardized benchmark results in the database, so the wins above derive from specification analysis rather than measured performance.

Architecture Differences

The two chips come from different architectural generations and design philosophies. The RTX 4050 Max-Q uses the AD107 die based on Ada Lovelace, built at TSMC's 5 nm process with 18,900 million transistors on a 159 mm² die. The N1 20SM uses the GB20B die based on Blackwell 2.0, also fabricated at TSMC's 5 nm process, but on a substantially larger 382 mm² die. Transistor count for the N1 20SM is listed as unknown, though the die area difference suggests a significantly higher integration level.

The transistor density metric applies only to the RTX 4050 Max-Q at 118.9 million transistors per mm². The N1 20SM lacks a recorded density figure. Clock behavior diverges sharply: the RTX 4050 Max-Q has a base clock of 1140 MHz and a boost clock of 1605 MHz, while the N1 20SM runs a lower base of 741 MHz but boosts to 2346 MHz. This 741 MHz base-to-boost delta of 1605 MHz on the N1 20SM indicates a power-optimized idle state with a high-performance boost bin.

Shading unit counts are identical at 2560 for both, and both use 20 RT cores and 80 tensor cores. The TMU count differs: 80 on the RTX 4050 Max-Q versus 160 on the N1 20SM. ROP counts also differ: 48 versus 24. The N1 20SM's higher TMU count aligns with its compute orientation, while the RTX 4050 Max-Q dedicates more ROPs to display and raster output.

Memory architecture represents the largest divide. The RTX 4050 Max-Q uses 6 GB of GDDR6 on a 96-bit bus at 2000 MHz (16 Gbps effective), yielding 192.0 GB/s bandwidth. The N1 20SM uses 128 GB of LPDDR5X on a 256-bit bus at 1067 MHz (8.5 Gbps effective), yielding 273.2 GB/s. The N1 20SM's unified memory pool is 21.3 times larger and offers 42.3% more bandwidth.

Power and interface details reinforce the split. The RTX 4050 Max-Q carries a 35 W TDP with no power connectors and an IGP slot width. The N1 20SM lists TDP as unknown, also with no power connectors and IGP slot width. The RTX 4050 Max-Q uses PCIe 4.0 x8, while the N1 20SM uses PCIe 5.0 x16. Display outputs differ as well: the RTX 4050 Max-Q is portable-device dependent, while the N1 20SM provides a single HDMI output.

API support is a critical differentiator. The RTX 4050 Max-Q supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4. The N1 20SM lists N/A for DirectX, OpenGL, and Vulkan, meaning it cannot run conventional graphics APIs. The N1 20SM's role appears to be compute or special-purpose acceleration rather than general-purpose GPU rendering.

Head-to-Head Benchmarks

No head-to-head benchmark results exist in the database. The winsA and winsB fields both show zero, and the headToHeadBenchmarks array is empty. This means all comparisons must rely on recorded specifications.

The most significant compute gap appears in FP32 throughput. The N1 20SM's 12.01 TFLOPS exceeds the RTX 4050 Max-Q's 8.218 TFLOPS by 46.2%. Both deliver FP16 at a 1:1 ratio with FP32, so the same percentage advantage holds for half-precision workloads. Texture rate amplifies this lead: 375.4 GTexel/s versus 128.4 GTexel/s, a 192.4% margin that stems from the N1 20SM's doubled TMU count.

The RTX 4050 Max-Q counters in pixel throughput. Its 77.04 GPixel/s beats the N1 20SM's 56.30 GPixel/s by 36.8%. This advantage comes from 48 ROPs versus 24, despite the N1 20SM's higher boost clock. Memory bandwidth also favors the N1 20SM at 273.2 GB/s versus 192.0 GB/s, a 42.3% difference, while memory capacity favors it overwhelmingly at 128 GB versus 6 GB.

Clock behavior shows a mixed picture. The N1 20SM's boost clock of 2346 MHz runs 46.2% higher than the RTX 4050 Max-Q's 1605 MHz boost. However, the RTX 4050 Max-Q's base clock of 1140 MHz is 53.8% higher than the N1 20SM's 741 MHz base. The N1 20SM's wider boost range suggests a more aggressive power-management curve.
