Corona GPU... AGAIN

[rhdesign]

I am a corona user since version 1.5 and i 'm using corona and few other renderers (Vray next .Redshift ,Lumion9.5 Pro) for rendering my projects  but it seems corona is my favourite ... ✔🙌    B U T    I do not understand why you are starting to bring some sort of old fashioned  reasoning and arguments for each item you do not want to promote, which is unacceptable to me...So how did  V-ray come up with his new benchmarking system and it worked great!!!did they lost anything valuble as they changed their whole benchmarking system..you know i dont really care about corona benchmarking system,,but actually im talking about GPU rendering or HYBRID rendering,nowadays every Artist , designers know that the difference between CPU and GPU rendreing is enormous.just look  at the your top benched rigs..omg. quadruple cpu each costs almost $10000 dollar which means $40000 holy crabs ..how many people are able to got such hefty system in the entire world????or xeon platinum 8180 Solid $15000 dollar for a single cpu...ordinary people just go by single processor in about $300~$1000 and professionals with something around $2000 at most lets say we are optimistic guys...but look at that x4 nvidia rtx 2080 ti costs only half of the single xeon cpu AND JUST LOOK AT RESULT ..imagine how would a final render looks like when all with ray tracing technology enabled...Vray GPU has this option on and in near future all of the other engines will be armed to this technology in their upcoming versions,,today is not the day to showing people A TANK example that u did in your website to convince them for using cpu is way better and beneficient  than gpus..just look at the statistics and charts about using cpu ,gpu,,IT IS NOT EVEN COMPARABLE......BTW...I SHOULD MENTIONED THIS !

rhdesign it's not fair to compare only cost, maybe you test this config and tell how long GPU will work compare to CPU, what PSU it needs, what case for 4 cards etc. How stable you GPU render and can you work in another program during render? Many things you are missing. And you comparing gaming device - GTX2080 with not gaming platform xeon platinum. You know Nvidia have also expensive professional cards and other accelerators Looks NVIDIA Tesla V100 price  =), it just CPU much stable what can handle different calculation without new cards and stuff, i mean raytracing before was pci cards if you remember caustic firm what bought brazil r\s for that.

ok is Chassis so important to you!!how about the chassis for 4 cpus??each intel xeon 8176 consumes 165Win normal mode it can be 200w at maximum so what the mighty 2080ti consumes 250W  and im wondering about what you said ...i should say price is everything when it comes to comparing ,single xeon 8176 is around $10 Geez.howm,any people are out there to invest such huge amount for just a cpu with 28cores..,.why render legion cant do this for its customers,,so every one can benefits from that and if you dont lile it just go with cpu rendering ,you dont have to use hybrid one,,is it so hard for them?
 or they are unable toadd this feature..as long as they merged with chaos group ,i cant believe that they are unable to do so...so there is no debate on this...gpu rendering fans are incresing day by day and someday they admit the fact ..i imagine how great could it rendering with both cpu and gpu in corona.....i love corona renderer and im a huge fan of it ..im just asking them add this feature ..and make CORONA the absolute solution for every kind of rendering...love you guys..wish you best luck.

It's not as simple as adding a feature :) The architectures of the cores and the way they process things are very different, so the code needs to be very different - it's pretty close to needing an entire re-write of the core. Add in that there are inbuilt limitations to GPUs (if the speed boosts, ease of use etc. was as good as some claim, it is true that everyone would be using them - the fact that CPU rendering is still the choice of many shows that those limitations DO matter to customers, and one thing we want Corona to be is "throw anything at it, and it just works" rather than "be sure to optimize this, limit the use of that" and so on).

So it would be a vast amount of work, and for many of our customers (based on our intimate knowledge of their needs) it would not bring anything they could use on a regular basis. While we never say never, and we will continue to watch the technologies involved, it's just not feasible for us at this time given the work vs. benefits and restrictions. You can see https://corona-renderer.com/features/proudly-cpu-based and the related https://corona-renderer.com/features/the-cpu-advantage as always :)

BTW, this has nothing to do with the Benchmark, and should have been started in its own thread (or continued under one of the previous GPU threads).

We can easily fix that...
