rtx a4000 or rtx 400

JImW

I'm about to buy a new card for my machine since my old card (2gb) just can't hack it for daz.  I have two options, refurbs, either rtx a4000 16gb or rtx 4000 8gb. Which is better for rendering on Daz3d? Some say it's all about the gb when it comes to Daz, but I don't know how true that is.

That is definitely true... so just go for RTX A4000.

Thanks. One thing I noticed was base clock speed in the lower card rtx 4000 is twice as fast as the a4000. Does this make much difference? 
And I know this might sound like a silly question, but do you know if all RTX a4000 are 16gb? I thought they only came in one size

If the scene won't fit into memory then the speed is irrelevant - on the other hand, if your scenes do usually fit into either card thenm the faster is the better. So, the relevant question is how demanding your scenes tend to be and whether you intend to make them more so in future.

That makes no difference at all... on the contrary, RTX A4000 is Ampere architecture with 6K Cuda cores which is much faster than Quadro RTX 4000 which is Turing with only 2.3K Cuda cores...

One of my cards is RTX A6000...  AFAIK, there's only one model of A4000 with 16GB. https://www.techpowerup.com/gpu-specs/rtx-a4000.c3756

Thanks all.
