Some good news coming to Blender...!

Up until now it was a privlege of Thea and ie Vray that you had the option of rendering hybrid! That means full use of GPU and CPU at the same time!
Well in Blender 2.83 its here...and its sort of faster!
But on top of that it enables smaller Ram cards to render bigger scenes!!!! :mrgreen:

Excellent!

I saw and tried an earlier experimental Blender that used cpu + gpu but it was like the current Daz-Iray -- the computing power of the selected devices is used but the scene still had to fit in the smallest device's memory. If it now has the advanced memory handling that is appearing in renderers that's great!

Cpu + gpu does not necessarily mean large memory use. Don't make the mistake of thinking it does. Plenty of renderers have had gpu + cpu rendering for computing power but no memory advantage for quite a while. Look for specific claims of out-of-core or other advanced memory techniques. Then look for independent testing to confirm that the claims aren't just hype or test it yourself. Advanced memory handling will become the norm for gpu renderers since they will not be competitive with out it.

Out-of-core memory is in several renderers now and coming soon to others. That has had academic papers and experiments for many years but it is seeing practical application now. It allows gpu access to system ram so big scenes can be rendered. This is slower than pure gpu rendering but faster than cpu only.

It is worth noting that gigantic numbers of polygons, enormous textures, and uncountable objects seem unnecessary or avoidable in many cases. Rayman often points out the merits of instances and other things to reduce memory use. Draise points out the merits of rendering parts of a scene to composite later. On the other hand one of my rules for lawn care is "make machines do the work" and when a scene really does have to be that big it would be nice to throw some gpu speed at it, and as Rayman noted it lets budget cards do larger scenes.

YupI'm nor sure though if its just a test buuld or comes with the final but they are working on it!
Which is very good news!

I guess 8Gig on GPU is enough, so in my case, is it fastest to render GPU only??

yup if 8 gig is enough and the scene loads..gpu is in most cases much faster! Maybe not realtime but fast ..very fast!
