CPU time to Bake database

I created a simple scene with Unity 5.3 , only some cubes.

http://www.zugsoft.com/unity/Bake.zip (32Kb)

Just open the scene "Simple" , open the Lighting Windows, and click on Build.
If you want to Bake again, you have to clean the directory \AppData\LocalLow\Unity\Caches\GiCache to be sure Unity will not use previous GI

Could I suggest you add some very large objects e.g. 100 units or larger as well as some spheres and a few different materials to actually push the GI engine.

Eg classic GI raytrace test looks like this:



or this scene is used a lot.



Edit -> You can find the above Sponza and versions of it here -> http://graphics.cs.williams.edu/data/meshes.xml

 

Out of curiosity, I did a quick overclock to 4.4GHz and reran the light bake.

Time: 1 minute and 24 seconds

I really thought that big of an overclock would lower the time by more than 2 seconds!

 

I am very frustrated, with my $4000 computer bought 3 years ago.

That should whip the stuffings out of my 8350.

Did you happen to use some utility to make sure the bake job was utilizing all cores?

Mine was averaging right around 92% usage on all 8 cores.

I would say it is the difference between a server chip and a "regular" chip, but the Bulldozer line is as crazy an architecture as they come...

@Arowx I only tried this cause I saw it would take a couple of minutes but would have skipped Sponza or anything else taking +5 minutes

 

It depends on the setting used in GI, note that the Bake setup is very low quality, probably not the quality settings you would actually want to build to.

 

I think it would be more interesting to try more complex scene, that usually takes several hours.
With very simple scene you won't be getting much data.
To make this kind of scene you could just make several untextured apartment buildings (out of modules) that include (empty) interiors and attempt to bake them.

Then you could start ramping quality up, by enabling final gather, etc.

 

Tested on three Unity versions installed on the same machine. Seems not much has happened on the baking perfomance front...

The settings are very low and the scene very simple, what you are more or less measuring is the overhead while enlighten switches to the various stages of baking.

 

But myself, and surely some of the others who posted results, aren't going to let our computers be blocked by baking benchmarks for some hours. I never use baking and it wouldn't have been worth the time to me, to take part in a more meaningful benchmark. You guys can start a "proper" one if you think you can get enough people to let their PC bake over night or something like that. Maybe a few tests of people with different hardware, who did the small bake test too, would be enough to extrapolate the data to see if the small test likely produces meaningful results or if there are big relative differences when testing a proper scene?

 

Yes I could create a very complex scene, but I created a simple scene to stay under 2minutes.

It's enough for me to see a i7-6700 @ 4Ghz > i7-4930K @ 4.3GHz > i7 3820 @3.7GHz > i5 4570s @3.2Ghz > 2x Xeon x5680@3.3Ghz > AMD FX-8350 4.0GHz

I did the test many times on my Bi Xeon computer, and it's always the same.
I remove the automatic frequency adjustment, and set the frequency to 3.5Ghz, and I improve just a bit my time : 1.17s

 

How are you getting the timings, is it from the consoles Log?

What about the other information in the consoles Log file e.g. timings for each step of the GI process, could give people a better idea of what is faster on what hardware e.g. SD drive, more-cores, memory.

 

Some hours no, but like 10 minutes should be doable, no?

As I said, as it is now, we are mostly measuring the overhead since barely any actual calculation happens.

 

I did a new test with my 2x Xeon @ 4Ghz, 49.15s

Dell XPS-13 (model 9343) laptop, about 2 years old. Did better than I expected, I guess it's the SSD.

Do I get a prize for the lowest CPU clock speed here?
Later on I'll try it on my wife's much newer 8-core desktop.

 

Seems like your prize is the second highest bake time so far

 

Thought my wife's machine would do better than this with the RAID0, 8 cores, and high clock, but:

Unity Version : 5.4.1p4
CPU : AMD FX-9590 8-core @ 4.7GHz
RAM : 32 GB DDR3
HD : 512 GB Crucial SSD (2x in RAID0)
Time : 1m 10s

Off-hand I don't remember the SSD or RAM details beyond that. Also that box runs a bunch of background junk that I suspect may hamper things (had Facebook notifications popping up the whole time, and everyone knows Adobe feels they have a devine mandate to run 20 frigging background processes 24/7). Maybe I'll set up another bare-bones profile and try again.

 

Unity Version : 5.4.0f3
CPU : i5 2500k 3.3ghz
RAM : 8GB
HD : WD Cavier Green 2TB
GPU : HD4850
Time : 1m 25s

It's basically a piece of crap apart from the CPU. Also, what is the point of Final Gather? I know what it's supposed to do, but it makes almost no difference to the scene compared to the time it takes.

 

That's basically the same rendertime as my old quadcore i7 3820 @3.7GHz and I always have a ton of background processes running too (right now task manager says it's 76). I doubt it affects the result significantly.

 

Did a few more passes on my laptop. The times varied over a range of 15 sec, which makes me question the validity.

Best result, but the earlier one at 1m 55s was probably average, I didn't actually record all of them:
