Hello,
I am a bit of novice and I was only asked by my collegue to do a research why is his old PC is rendering faster than his new monster PC that was bought specifically for rendering purposes and to be super fast. Both run the same software and OS(win 7 64bit)
Specs for both computers:
Old one - i5-760 (4 Cores/Threads @ 2.8GHZ), 8 GB RAM, and GeForce GTX 550 Ti 1GB, Western Digital HDD drive 1TB 7200RPM
New one - i7-3930K(6 Cores, 12 threads @ 3.8GHZ), 32GB RAM(!!), Quadro 2000D 1GB, SSD 120GB Kingston.
What we are rendering - a 1.5minute animation on 3DS max 13 64bit. We started on Default Scanline Renderer on Old PC it takes 3h 30minutes, on New PC - 4h 30minutes! OK, then we realized that Scanline renderer isn’t using GPU at all. Next up Quicksilver Hardware Renderer(Direct3d) - Old PC - 36minutes, New PC - 46 minutes! Turned out Quicksilver is no good for us, it wasn’t rendering in Full HD, but instead rendering it to 640x480 while still rendering it shows correct resolution. Went to iRay(GPU) - 11 hours on Old one, 12 hours on new one - too long. Mental Ray (CPU) - 10 hours vs 12 hours accordingly. Got our hands on Vray-RT that finally utilizes CUDA cores and should be a lot faster - nope, around 30 hours when CUDA selected on both PCs.
Can anyone tell us, what exactly could be cause of this? And why is Old PC render times 1/4 faster than New PCs while CPU rendering? It’s simply impossible and I have no explanation for this.

turn off hyperthreading in the bios and retest. IIRC, some functions in 3ds dont take well to HT.

Thanks for the answer, and while it actually did lower rendering time, the i7 render is still 15 minutes slower than i5's, but I will try some more options on BIOS, and will give you an answer shortly.

Check that the ram on the i7 is in quad channel mode.

The new rig doesnt list a storage drive and I dont beleive the SSD would provide enough room. Are you using a 7200rpm HDD?

I tried several settings on BIOS regarding previous post about HyperThreading, now that I disabled it was faster, nothing really changed after different settings.
on motherboard where is Quad Channel option? Checked all over BIOS, and there are no such features. Do I have to select it through some jumper setting on motherboard? All I found is Performance Enhance option on RAM settings, set it to Extreme - was on Turbo before. Will get back after I check out manual of the MB.

hi ,
i have same problem with my intel core i7 3770K , i do this 2 : 1) turn turbo mode on bios , and set poweroption in my windows 7 poweroption to high performance and then my render time do 40% to 45% faster , before it when i have intel core i5 3330 cpu and compare it with i7 3770k render time only 5% to 10% is faster, i hope this solution is helpfull

Both video cards have the same amount of cuda cores and memory so they should render in equal speed, about the scanline renderer behavior, scanline can't perform GPU rendering, only Iray and V-Ray RT can. Now, the reason for scanline to be so slower in the new computer is unexplainable, at least that there were some change of settings involved when you switched to the new computer. For ex. set shadows using Advanced raytrace render to shadows using Ray trace, because the last type render very slow.
