The RTX A4000 is a professional graphics card by NVIDIA, launched on April 12th, 2021. Built on the 8 nm process, and based on the GA104 graphics processor, in its GA104-875-A1 variant, the card 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 16 GB GDDR6 memory with the RTX A4000, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 735 MHz, which can be boosted up to 1560 MHz, memory is running at 1750 MHz (14 Gbps effective).
Being a single-slot card, the NVIDIA RTX A4000 draws power from 1x 6-pin power connector, with power draw rated at 140 W maximum. Display outputs include: 4x DisplayPort 1.4a. RTX A4000 is connected to the rest of the system using a PCI-Express 4.0 x16 interface. The card measures 241 mm in length, 112 mm in width, and features a single-slot cooling solution.
