The RTX A4000 Mobile is a professional mobile graphics chip by NVIDIA, launched in April 2021. Built on the 8 nm process, and based on the GA104 graphics processor, the chip supports DirectX 12 Ultimate. The GA104 graphics processor is a large chip with a die area of 392 mm² and 17,400 million transistors. It features 6144 shading units, 192 texture mapping units, and 96 ROPs. Also included are 192 tensor cores which help improve the speed of machine learning applications. The card also has 48 raytracing acceleration cores. NVIDIA has paired 8 GB GDDR6 memory with the RTX A4000 Mobile, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 915 MHz, which can be boosted up to 1515 MHz, memory is running at 1750 MHz (14 Gbps effective).
Its power draw is rated at 140 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. RTX A4000 Mobile is connected to the rest of the system using a PCI-Express 4.0 x16 interface.
