Description

The NVIDIA GeForce RTX 4050 Mobile is a mainstream mobile graphics chip designed for gaming laptops and performance notebooks that target smooth 1080p gaming and GPU-accelerated productivity. Launched on January 3rd, 2023, it is part of the GeForce RTX 40 Mobile family and is built on TSMC’s 5 nm process using the Ada Lovelace AD107 GPU in its GN21-X2 variant. With full DirectX 12 Ultimate support, the RTX 4050 Mobile enables hardware-accelerated ray tracing, variable rate shading and other modern rendering features in current and upcoming games.

The AD107 processor powering the GeForce RTX 4050 Mobile is an average-sized chip with a 159 mm² die area and 18.9 billion transistors. Compared to fully unlocked AD107 configurations, NVIDIA disables a portion of the shader resources to meet the performance and power targets for this segment. In this configuration, the RTX 4050 Mobile exposes 2560 shading units (CUDA cores), 80 texture mapping units and 48 render output units, along with 80 fourth-generation Tensor Cores for AI workloads and 20 third-generation RT Cores dedicated to ray tracing acceleration.

Clock speeds for the 50 W reference configuration are set to a base clock of 1455 MHz, with boost frequencies up to 1755 MHz depending on thermal and power headroom within the laptop chassis. At these clocks, the RTX 4050 Mobile delivers around 8.986 TFLOPS of FP32 compute performance, matching FP16 throughput at a 1:1 ratio, and achieves theoretical pixel and texture fill rates of 84.24 GPixel/s and 140.4 GTexel/s, respectively. These characteristics provide solid performance for high-quality 1080p gaming and some lighter 1440p workloads when combined with DLSS and tuned settings.

NVIDIA pairs the GeForce RTX 4050 Mobile with 6 GB of GDDR6 memory connected through a 96-bit memory interface. The memory runs at 2000 MHz (16 Gbps effective), for a total bandwidth of 192 GB/s. The GPU also features 12 MB of L2 cache and 128 KB of L1 cache per SM, which help improve effective bandwidth and reduce latency in complex scenes and compute-intensive titles. While 6 GB of VRAM is clearly mobile oriented, it remains adequate for many contemporary 1080p games when texture and graphics presets are selected appropriately.

The RTX 4050 Mobile is designed with a 50 W TGP in its baseline configuration, with higher-power variants scaling up to over 100 W depending on OEM tuning, as noted in board design and clock notes. This low-to-moderate power range enables integration into a wide variety of notebook designs, from thin-and-light systems to more robust gaming laptops, without requiring dedicated external power connectors. The GPU connects to the host system over a PCI Express 4.0 x8 interface, which offers enough bandwidth for its performance class and mobile usage scenarios].

As with other Ada Lovelace-based mobile GPUs, the GeForce RTX 4050 Mobile supports DirectX 12 Ultimate, OpenGL 4.6, Vulkan 1.4, OpenCL 3.0 and CUDA 8.9, ensuring broad compatibility with modern game engines and GPU-accelerated applications. The AD107 feature set includes 8th-generation NVENC and 5th-generation NVDEC engines, benefiting streaming, video editing and media playback on supported laptops. Overall, the NVIDIA GeForce RTX 4050 Mobile offers a well-balanced mainstream laptop GPU for gamers and creators who need efficient 1080p performance, ray tracing and DLSS capabilities in portable systems with constrained power and thermal budgets.
