I am going to buy a new Desktop and kindly need some professional advises regarding to best hardware requirements for analyzing satellite images specially Radar (Sentinel) data without any trouble or time wasting.
(how many GB RAM? What types of processor? What type of graphic card? Which operating system?( Does Snap install under Mac also?)
Would be appreciated to advise me regarding this issue.
Hello all, I’m also interested in this topic. I’ll have to work on sentinel1 and sentinel2 images to extract data concerning agricultural indicators and I was wondering which hardware will suits better, still keeping reasonable budgets. I’ve been adviced for the following specs that seems to me a bit too high, but I’m new in these matters and I don’t want to be stucked in the coming years.
RAM between 32 and 64 Gb,
Quad-core processor minimum,
SSD-disk of 1 Tb for calculations,
HD of 10 Tb for storage.
I am planning to buy a new laptop and I am wondering whether the processor type Intel i5 or i7 matters when using SNAP? For example, i5-8265u vs. i7-8565u. Is it worth spending money on i7 in this case?
I am mainly working with Sentinel-2 images now.
So if to choose whether to buy a laptop with i7+16GB RAM or a laptop with i5+>16GB RAM, the latter one would be better? Just trying to figure out whether to pay for i7 (would it make a difference from i5) or better to invest to more on RAM.

Hello in this regard, is better a laptop with a processor from AMD - Ryzen 7 4800H OR from Intel - Core i7-9800X @ 3.80GHz.
In some search, I feel that since Software SNAP makes use of multiple cores is better this particular AMD than INTEL.
Any other opinions?
Both can run 16 threads in parallel. So both should do a good job. The intel CPU is older than the one from amd you mentioned and the intel one is for desktops.
Having these two options I would go for the amd cpu.
Thank you Oana. Yes, i found is something about RAM requiments. However, about graphic card i didn’t find out nothing. In your opinion, for sar processing and post processing (e.g. GIS), is better an integrate or dedicate graphic card?
Most (all?) SNAP operators don’t use the GPU, so I suggest getting an integrated one and maybe spending more on a faster CPU or more RAM (or just saving the money). You should also be mindful on the heap size, but that depends on how you’ll be running it (SNAP or GPT). A larger Java heap won’t always result in better performance.
Integrated graphics in current systems is quite robust, older versions often had annoying limitations. RAM usage often depends on what apps are being used concurrently with SNAP. Web browsers and GIS software can use big chunks of RAM.
