GPUs for using Vantage not on daily base - RTX A4500 a good choice ?

[robert_ecker]

Hi!
Just started to take a look at Vantage and i'm quiet impressed!
I'm using 3ds Max & Vray 6 for CPU-rendering only... yet .
Because of using Railclone and ForestPack for 95% of our environments, switching to RT Engines was not very efficient -> so GPU rendering wasn't on my focus and therefor i have only a little knowledge about what GPUs specs are really important.

So if i decide to use Vantage more often, i definitely need to upgrade my GPU ( RTX 2070 ).
But the usage wouldn't be on daily base, just in case if you do some additional interior / exterior animations on mid-ranged architectural projects.

There are many cards out there but i'm not sure if i need the latest RTX 4080 just to have as much power as possible.
I'm also limited for the max card-length of 3200mm -> what i see so far there are only some 3080s or lower in that range.

So i was researching for cards and their cores, rams checking the vray benchmarks etc - so got 3 "finalists": RTX 3070 Ti, RTX 3080 (Ti) and RTX A4500, here the Vray Scores:

RTX 3070 Ti:
1350 CUDA, 1880 RTX

RTX 3080 / Ti:
1750 / 1750 CUDA, 2300 / 2775 RTX

RTX A4500:
1380 CUDA, 1900 RTX


Now my questions:
1. To understand the Vray Benchmarks: The RTX 3080s CUDA-Score is 3.8 x higher than mine, the RTX-Score is 3.5x higher -> does it mean when my card renders 35 seconds per frame the 3080 takes 10 seconds? And what score is "more" important for vantage RTX or CUDA or both ? Sorry for that maybe stupid question
2. RTX A4500 and RTX 3070 Ti are quite similar with cores and at the vray benchmarks, but what difference/benefits makes the higher priced A4500 -is it the ram-size only ? I have to say the A4500 is on my list because of it's length, powerusage and ram-size.
3. What would the benefit of a A4500 "workstation-card" over a 3080(Ti) "gamers-card" ?
4. What do you think about the Aorus Gamingbox 3090 as an alternative - because the 3090 is too long for my actual workstation.

Would be awesome to hear what you think about it - and thanks in advance

1. Vantage always uses the RTX technology, so that score is more relevant. Still, the V-Ray Benchmark uses V-Ray GPU, while Vantage is a separate render engine, so results might differ.
4. I think the 3090/3090 Ti GPUs are obsolete now that there is the 4090 - it's at roughly the same price, but 2x faster.

Hello,
Some of the 3090s are 32 CM in length or smaller, look for Asus TUF Gaming 3090, other 3090s from PNY and INNO3D should fit in your case

1. To understand the Vray Benchmarks: The RTX 3080s CUDA-Score is 3.8 x higher than mine, the RTX-Score is 3.5x higher -> does it mean when my card renders 35 seconds per frame the 3080 takes 10 seconds? And what score is "more" important for vantage RTX or CUDA or both ?

This scaling should be close yes, the 3080ti/3090 are a lot faster than your current GPU
And like what Vlado said above, the benchmark uses V-Ray GPU RTX mode.. it is a different renderer to Vantage, but again the performance scaling should be representative to what you will see in Vantage

2. RTX A4500 and RTX 3070 Ti are quite similar with cores and at the vray benchmarks, but what difference/benefits makes the higher priced A4500 -is it the ram-size only ? I have to say the A4500 is on my list because of it's length, powerusage and ram-size.

The difference is mostly memory size yes, hence the A4500 will be a lot more expensive, nearly triple the price

3. What would the benefit of a A4500 "workstation-card" over a 3080(Ti) "gamers-card" ?

Other than memory, there is no difference between these GPUs. The chips are used between the 3090 and Quadro A6000 for example
That being said, the Quadros are a lot more expensive, so people lean towards Geforce(gaming)cards

4. What do you think about the Aorus Gamingbox 3090 as an alternative - because the 3090 is too long for my actual workstation.

Should work fine, although you don't get 100% of the performance using external GPUs. My advice here is to find one of the small form-factor 3090s

Let me know if you have more questions

Best,
Muhammed

Hi Vladimir and Muhammed!

Thanks for your tips

Just recognized that the RTX 4080 Founders Edition's length is slightly longer than 3000mm - and it's cheaper than the 3090 Ti or A4500 Does the DSSL3 have an impact on working with Vantage ?

So i'll better try this card
