The RTX A400 is a professional graphics card by NVIDIA, launched on April 16th, 2024. Built on the 8 nm process, and based on the GA107 graphics processor, the card supports DirectX 12 Ultimate. The GA107 graphics processor is an average sized chip with a die area of 200 mm² and 8,700 million transistors. Unlike the fully unlocked GeForce RTX 3050 8 GB GA107, which uses the same GPU but has all 2560 shaders enabled, NVIDIA has disabled some shading units on the RTX A400 to reach the product's target shader count. It features 768 shading units, 24 texture mapping units, and 16 ROPs. Also included are 24 tensor cores which help improve the speed of machine learning applications. The card also has 6 raytracing acceleration cores. NVIDIA has paired 4 GB GDDR6 memory with the RTX A400, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 727 MHz, which can be boosted up to 1762 MHz, memory is running at 1500 MHz (12 Gbps effective).
Being a single-slot card, the NVIDIA RTX A400 does not require any additional power connector, its power draw is rated at 50 W maximum. Display outputs include: 4x mini-DisplayPort 1.4a. RTX A400 is connected to the rest of the system using a PCI-Express 4.0 x8 interface. The card measures 163 mm in length, 69 mm in width, and features a single-slot cooling solution.
