The RTX A4000 Mobile is a professional mobile graphics chip by NVIDIA. 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. Unlike the fully unlocked GeForce RTX 3070 Ti, which uses the same GPU but has all 6144 shaders enabled, NVIDIA has disabled some shading units on the RTX A4000 Mobile to reach the product's target shader count. It features 5120 shading units, 160 texture mapping units, and 80 ROPs. Also included are 160 tensor cores which help improve the speed of machine learning applications. The card also has 40 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 1745 MHz, memory is running at 1500 MHz (12 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.
