laptop GPU for photoscan processing
« on: March 11, 2015, 09:24:18 PM »
Hi, a lot of the scanning i am starting to do involves being away from my workstation and  I'm really being let down by the speed my current laptop is taking to process even low quality meshes. Can anyone recommend a GPU on a laptop that would do a decent job.

Currently i am thinking either quadro - 1100m/2100m or gtx range - 965m/970m

anyone have experience of either range and can tell me which is better for agisoft as I will be primarily doing quick meshes for the cleint/myself to preview the scanning process. Heavier processing can be done on another dedicated non mobile workstation.

any benchmarks for laptop gpis?

thx

I have a Dell M3800 that I use every once in a while when the workstation is chugging away and I want to do something small. When I get home I can run the benchmark and upload the results if you like.

Specs are as follows:
Intel i7-4702HQ
Windows 8.1 Pro
16GB DDR3 1333
Crucial M500 960GB SSD
Quadro K1100M 2GB DDR5

Here you go, using the benchmark data and my M3800 laptop. Both tests were done with CPU 6/8 and Quadro card activated.

High/Medium (alignment/dense cloud)
Device 1 performance: 69.52 million samples/sec (CPU)
Device 2 performance: 108.952 million samples/sec (Quadro K1100M)
Total performance: 178.472 million samples/sec
Finished processing in 1301.61 sec (exit code 1)

High/High settings (alignment/dense cloud)
Device 1 performance: 67.4911 million samples/sec (CPU)
Device 2 performance: 110.95 million samples/sec (Quadro K1100M)
Total performance: 178.441 million samples/sec
Finished processing in 4112.75 sec (exit code 1)

thank you so much, the m3800 was one i was considering getting , just the k1100 card putting me off in terms of performance vs a gt card, i will run the benchmark on my macbook gt650  and compare, really keen to see a gt970 benchmark

I have access to a ASUS G75 laptop running a GTX 980M. Ill see if I can get a demo trial running on the laptop and bench it

cheers, would be amazing to see that im convinced the gt card will be quicker but most gt970/80s are gamers laptops and weigh a couple of kilos and have neon yellow alien graphics all over them.

I will say ive been 100% happy with my Dell Workstation PC. Its my 3rd one and they are amazing machines. Warranties are amazing as well. Next business day replacement of parts when needed, even if the motherboard goes out. Cannot beat that.
