General / Re: Another workstation build question
« on: August 25, 2015, 02:02:51 PM »
1) Is it worth running two intel CPUs if I want to use GPGPU processing for the point cloud building, or am I better to spend the money on two GPUs to speed up the depth map building/point cloud generation? Am I better to go with 4 core 4 Ghz CPUs over 6 core 3.3 Ghz?
     I dont think the extra money is worth it going to 2 CPUs. I would rather save the money and purchase a better single CPU mobo, more ram and a faster single CPU

2) Can PS utilize two GPUs?
    Yes, it will utilize as many GPUs as you can throw at it

3) Does GPU memory size make much difference? aka am I better to go with lower memory CAD cards for the same price as gaming grade card? I had read that PS can't really make use of the CAD cards due to only using single precision calculations, but that doesn't mean anything to me!
     I dont believe so, I may be wrong. I used a Tesla card for some time and was able to monitor the memory useage and it never seemed to go over 1MB of use.

I was looking at the radeon cards, as I read they are better for OpenCL processing, and was looking at the R9 390 or the HD7970, for around the same price. How do you choose between them?
     The R9 390 would run cooler, and pull less power. This would give you the ability to run multiple cards.

4)Does RAM speed make a lot of difference? Following the spec sheet, we need around 128 GB of RAM to process the number of photos we are looking at, possibly even more. Given our limited budget, we are really looking at DDR3 ram. But would DDR4 be a significant advantage? Would DDR3 2133 be a worthwhile advantage over DDR3 1600?
     I have not seen any difference from upgrading from DDR4 2133 to DDR4 3000

5) Does a RAID 0 HDD cluster speed things up, or are all the speed gains in the processing? Would I be better off just using a high RPM HDD?
     Just go with a 1TB SSD as a working drive. They are dirt cheap now and will make sure the data is geting to and from the CPU/RAM as fast as possible

I had a AsRock X99 WS-E for less than 60 days and it died. Got a seond one sent out to me and it was dead within 15 days. BIOS would literally just erase itself and no longer boot. The strange thing is that I never even changed anything in the BIOS, I had one on the latest version and the second on the one before and both had problems. Switched to a ASUS X99 WS board and have been stable ever since.

Its just going to be a bunch of 1080p cameras connected to it. Its main use will be for Youtube 360 videos.

Personally I run 2 GPUs and 2 Tesla co-processors, but everyone has their own needs. I do lots of ray tracing that requires the Nvidia Tesla cards to be done quickly.

Id recommend the ASUS X99E-WS motherboard if you can get it. I had the X99-A and is was OK, but I had some stability issues when running 8 stick of RAM. The nice thing about the E-WS is that you can also run ECC RAM allowing a max of 128GB of RAM.

General / Re: Intel Core i7-4700MQ vs i7-5960X - performance boost?
« on: June 22, 2015, 07:18:45 PM »
That would be a good estimate

I have a  i7-4702HQ in my Dell M3800 and I average 65-67 million samples/sec

My desktop has a Xeon E5-1650V3 and averages 87-90 million samples/sec

General / Re: Sharp video frame extraction software?
« on: June 22, 2015, 04:33:41 PM »
If there is a way to do this quickly I would love to hear as well. I am in the same situation where we pull every frame from video and manually go through each to find the best, sharp image. When the video is 30 seconds long and thats it this isnt bad, but most of the time we are dealing with 2-3 min long videos and then 5-8 different shots as well. When you have a folder of 50-100K images you need to go through for one project smiles turn to frowns really fast.

Take a look at the benchmark scores and it will give you a general idea of the performance differences.

Disable SLI and try again.

I would go with the 760, unless other programs you run require a Quadro card.

That mobo only supports 64Gigs or RAM though :/  I would like the ability to upgrade to at least 256 later. We will handle pretty large data sets later...

The ASUS board supports 128GB

The supermicro board will upgrade to 256GB but remember that the E5-1xxx series CPUs do not supprot dual CPU configurations so you will only be able to use 8 of the 16 slots on the board. That means you will limited to purchasing 32GB sticks of DDR3 at close to $500/stick. Also that 1603 CPU does not support hyperthreading, just a FYI

If it were me this is what I would do:

Monitor - LG 22M34D-B

Keyboard - Logitech MK120

Case - Corsair Air 540
I personally have this case and love it, good choice.

Motherboard - ASUS X99-E WS
Can be upgraded to 4 GPU later down the road if you guys ever need to.

CPU - Intel Xeon E5-1650 v3
You will thank me for this CPU choice over the 1603. Clock speed on the 1603 2.8, the 1650 is 3.5. Spending more money here and only going with 1 GPU will save you a lot more render time than having two GTX 970 video cards

RAM - Crucial 16GB DDR4-2133 ECC
See RAM comment below

CPU Cooler - Cooler Master Hyper 212 EVO
This CPU cooler is amazing for the price. I use it as my default for all builds.

Spinning HDD - HGST Deskstar 3TB
I just prefer HGST and have never had a problem with these at all.


PSU - EVGA 1200W P2
10yr warranty and platinum rating, enough said. Will support 3-4 GPU depending on their power requirements.

My recommendations above put you right at $2988.39 and give you a LOT of room to upgrade down the road.

The above comment about DDR4 is correct, it is a little more expensive right now, but the prices on DDR4 are dropping almost weekly since it is becoming the mainstream RAM. Pay a little extra now, but when you want to go from 64-128GB later it will be much cheaper than DDR3.

Okay guys, thanks for your advices. Btw. computer set up in the link I posted there - does it look any good?

Im using the same CPU and I love it. The GPU is on the lower end, but you can always add a second card later, depending on your PSU size. Other than that just buy a more RAM and upgrade it once you get the machine

Quadros also have uncapped FP64 performance, which is great for ray tracing. If your just going to use this setup for PhotoScan get a Nvidia card, if you are planning on doing other things with it research the other programs and see if they take advantage of double precision processing
