I have 2 questions:
1)witch card is faster render (rtx 3090 or rtx a6000)?
2)vantage is combining memory of 2 cards (NVlink)? if I put two rtx A6000 48gb I will get 96gb in vantage?
Hi @oleg_svirsky and welcome to the forum,
Both GPUs are using the same GA102 chip, The 3090 is 5 to 10% faster (depending on the model) as it comes with higher boost clocks and power draw

Chaos Vantage doesn’t support memory pooling, you are limited to 24 GB with 2x 3090s.. and 48 GB with 2x A6000s
Best,

is there is a plan to implement memory pooling?
@npg Could shed light on that topic 
It is on our “TODO” list to try this for Vantage at some point, but it’s not going to be near term as we also have other things to do. However, we already have some significant memory optimizations prepared that could help your scenes fit on the gpu. Not sure when this will be released though.
