Which processor for fast alignment and fuse operation?

Post by erol » 29 Aug 2018, 21:10

Hi all.

I have dell m4800 workstation (i7 4800mq, 16gb ram, k2100m and 250gb ssd)it is running slowly in alignment and fuse operations. It takes about 1 minute when I try to align single scan to group scan

My questions.

1-Hp (david sls) how many CPU cores are used in the calculation.
2-Which is the most important single-core speed or multi-core speed.
3-Which one do you recommend Intell i7 processor or amd ryzen7 processor.

I think I should take it.

amd ryzen7 1800x, quadro video card and 16gb ram

or

i7 7700k, quadro video card and 16gb ram

I don't know that David is multi threading and can take advantage of multiple cores. I also can't speak to Davids compatibility with non Intel processors. However I have spec'ed a new workstation and have done so with an 8th gen i7 (can't justify an i9) and here's why. Many of the other 3D mesh apps I use really don't play nice with anything but an i7. I have a Xeon and an older AMD machine and I have crash and memory usage issues with those machines. Of those two the Xeon is better but I also use Artec Studio and it does not support anything but an i7/i5. It really doesn't like the Xeon and crashes constantly on the AMD machine. I haven't tried to debug any of this to see for myself where these crashes and errors are coming from, but have spoken to tech support guys from both Artec and Geomagic and have gotten more or less the same story. That said AMD is "supported" by Geomagic". The i7 based machine I have which is now 3 years old practically flies with David (scan capture and mesh alignment). I can only imagine what a current i7 machine with lots of ram could do.

Micro,

Would you be able to take a video show your processing times with your setup? I’m mainly interested in aligning/fusing scans.

My current rig is painfully slow and would like to see how other setups are doing

Micr0 is very justified.
I did tests with two computers.
1.System
Dell M4800 i7 4800MQ 250SSD + 1TB HDD, Quadro K2100M, 16GB DDR3 RAM Win7
2 .system
amd ryzen 1800x, asus tuf b450, 250ssd + 1tb hdd, quadro k4000, 16gb ddr4 2400mhz ram win10

2. system better for 3D CAD modeling
1. system faster in alignment and fusion operations,
1. system 60% faster in the same piece of test 8.1min - 13min (global fine registration 55 scans).

now i'm thinking to replace my processor with i7 8700k or i9 9900k, but very expensive. Maybe i7 6700k also think

Wow you’d think the Ryzen core would blow the other right out of the water!!

Have you checked to see if the software is using all 16 threads during processing?

What resolution are you scanning at, Default?
With 55 scans I'd think that more ram may help you. 16gb isn't much by today's standards. If your mother board supports, it faster ram would be better too.

I surprised that the DDR4 and SSD of the AMD system didn't make more of a difference. That said the code for David may just be better suited for win7 and intel...

FWIW I far prefer win 7. I have no proof that its faster or slower in handling large mesh files though.

I did a test today and ryzen calculated it faster :D . All cores of ryzen were used during the process.
Result: ryzen: 1,42 min, dell m4800: 2,04 min

How many performance increases does 3200mhz memory?
