4090

V-Ray V-Ray GPU General

Any hands on? Benchmarks?

2

An other one.

Looking for the official Vray analysis. Too bad there’s no NVlink.

Looks like this card is a beast.

Hello everyone,

I shared our Benchmark numbers for V-Ray GPU in this thread, as well as notes on the thermals, power consumption for anyone who plan on buying the new GPUs
In Benchmark 5, The RTX Benchmark we see 125% faster renders with the RTX 4090 compared to the RTX 3090, and 116% faster renders in the Cuda Benchmark

I found this statement:
"Nvidia CEO Jensen Huang confirmed that the company is doing away with its NVLink bridge. Replacing NVLink is PCIe Gen 5, which Huang and Nvidia claimed will be sufficiently fast to connect multiple GPUs together, "

What does this mean? Will it be possible that we have a replacement for the NVlink feature over the PCIe bus?

Hello @Muhammed_Hamed , thanks for this. What would you do in combination with a 3990x? One 4090 or two 3090?
Thanks,
Hani

Edit: Found already the answer in another thread from you …

Hey!

I have my 4090 now, it is basically 2x 3090s running at much lower power consumption and temperature. I like this experience quite a lot
The only reason you would go for 2x3090s is NVlink, other than that the 4090 is as fast as 2x3090s and a lot easier to cool

Hi Muhammed,
yes, I thought so, too. But good to get it confirmed by you!

I will go for one 4090, too.
Which one do you have?

Thanks a lot!

They are working on a replacement yes, but we haven’t seen anything yet
I hope we will be able to see/test something soon

Asus TUF Gaming OC
But feel free to go for the cheapest one you find, the differences on the cooling/specs are minor for typical use(unless you plan on extreme overclocking)
Keep in mind these cards have cooling designed for 600 Watts, while running at 400 to 450 usually.. my card runs below 60 degrees on rendering

Hi Muhammed, I am just wondering what is your wattage during the vray rendering? Mine never go above 300W comparing to the 3090 which uses close to 350W, is it something with I dont use all 4 full pcie cables to the adapter (one is split)? Same with vray benchmark, but the results are good. All three cards have dual bios set to Power. F

Same here, it looks like GPU rendering doesn’t push these GPUs on power draw as high as some of the games does
In games I get 480 watts power draw which makes the GPU a lot hotter, and around 300 in Octane/V-Ray GPU
As long as the scores are fine, it is not an issue I think. On the bright side, the cards run very cool

Best,
Muhammed

This new 4090 is pretty impressive, got my Aorus Extreme waterforce(it`s the one with aio and 3 fans), and it never goes above 275W when rendering with V-Ray. Even after 1h of rendering, fans only spin at 30%(zero noise) and temp under 55C. Damn, I need to get one more :slight_smile:
