Interesting, but not the best comparison because the scenes are set up very differently in each case. The lighting is quite different, as you can see from the shadows under the table in the foreground.

The first image has some artificial fill lighting applied which has spoiled the overall render.

Bump and reflection settings are very different too.

Yes. I made a quick adjustment. I played some bump settings. I shouldn't have put a spotlight on. But I wanted to see it. I could turn the lights off and increase the exposure. I tried to comprehend the Bump thing. I want to ask something. What is bit depth? Podium bit depth 24, vray bit depth 32? I saw the details of the picture after rendering.

I don't understand what you mean by bit depth.

If you want a brighter image, you can use a different preset or use PIE. You really need to set scenes up so they look as close as possible to get an accurate comparison. You can't just keep the same settings.

For most materials, you need bump depth of 0.

You really need to try to match all the material settings for both images.

Ah, okay, that's dpi. That makes no difference really.

There is a complex relationship between resolution and dpi. This is effect pixel density.

It's of no consequence unless you want to print your images at a large size.

In the above example, the lem was used as the light source in both. HDRI was rendered on the podium side. Interior fine AA. Duration is 10 minutes. On the Vray side, this time is 45 minutes.

I think Dpi makes a difference. Image Editor prevents color fluctuations in settings. I think the new versions of the podium should be studied on this issue. I don't know if this is a hard work. I'm not a developer :)

No, seriously - this is really not important.

Colour fluctuations are caused by jpg or png compression. If you render to hdr, you don't get colour banding.

These are much better comparisons. The lighting is still not the same though.

You might need to use the high preset because of the ceiling blotches, and you don't have sunlight penetrating into the room on the Podium render - which the first one.
The washbasin material settings aren't right (looks like an LEM), and the wall light power is too high. 

However, these things might be the reason for the blotches.

Also the floor reflectivity on the first render probably needs to be reduced.

The blind material in the Vray render isn't realistic though - looks weird.

You are right. I think I accidentally made a lem :) These two comparisons are the reasons for doing. To illustrate the differences between the supodium rendering engine or any rendering engine. Some friends think that rendering engines will produce an extraordinary picture in a very bad scene (texture, model, details). These comparisons were for their better understanding.

I'm not talking about dpi. The color depth is mentioned. 16 bits contain 65536 colors and 32 bits contain 4294967296 colors. This event affects quality.

No, you are looking at the numbers too simplistically. Have a look here.
