Nvidia graphics card RTX A2000: Efficient mini-amp with 8 TFlops from 70 watts

With the RTX A2000, Nvidia would like to make its amp architecture fit for particularly small workstations. Although the card occupies two slots, it is only half the height and is also quite short at just under 16.8 centimeters. It is supplied via the PCI Express 4.0 slot and does not require a separate power connection from the power supply unit. From October it will go on sale through Nvidia’s usual sales channels. Nvidia named a price in advance only for the US market. Expect a street price of around $ 450. The much more powerful RTX A4000 meanwhile costs around 1200 euros, and the RTX A2000 will cost one euro when the card is released in October.

The RTX A2000 comes with four Mini-DisplayPorts 1.4 for high-resolution screens. It has a GA106 graphics chip, which is configured here with 26 shader multiprocessors. That means 3328 shader cores, 104 tensor and 26 raytracing cores from the current Ampere architecture work on the small card. It should create a computing power of 8 TFlops, which is very considerable for a thermal budget of only 70 watts. The small radial fan blows the heated air directly out of the housing.

Calculations for AI applications should run with up to 63.9 TFlops via the tensor cores – but with reduced precision and the sparsity feature of the ampere generation. How long it can maintain the necessary boost clock of around 1.2 GHz has yet to be checked.

The graphics chip of the RTX A2000 is supported by 6 GByte ECC-protected GDDR6-RAM, which transmits 288 GByte / s over 192 parallel data lines. The other features correspond to those of the larger sibling cards such as the RTX A6000 including the modern video unit, which also decodes AV1 clips and takes over the encoding of H264 / H265 and VP9.

Thanks to the ray tracing capabilities, Nvidia promises creative professionals in the design, construction and visualization industries, for example, a significant performance boost when using programs that address the ray tracing hardware of the graphics chip. In the Pro-Viz sector there are now a few such as Autodesk’s Solidworks Visualize with its Denoiser and the free rendering software Blender is once again picking up the pace with ray tracing via Optix.
