Connectivity and outputs

This section shows the types and number of video connectors on each GPU. The data applies specifically to desktop reference models (for example, NVIDIA’s Founders Edition). OEM partners often modify both the number and types of ports. On notebook GPUs, video‐output options are determined by the laptop’s design rather than the graphics chip itself.

Pros & cons summary

Performance score	2.80	46.56
Recency	22 July 2014	12 April 2021
Maximum RAM amount	2 GB	16 GB
Chip lithography	28 nm	8 nm
Power consumption (TDP)	33 Watt	140 Watt

GeForce 830A has 324% lower power consumption.

RTX A4000, on the other hand, has a 1563% higher aggregate performance score, an age advantage of 6 years, a 700% higher maximum VRAM amount, and a 250% more advanced lithography process.

The RTX A4000 is our recommended choice as it beats the GeForce 830A in performance tests.

Be aware that GeForce 830A is a notebook graphics card while RTX A4000 is a workstation one.
