Question

Ideal Mac Memory and Processor for Acrobat Pro OCR and Search Performance?

NOTE: this question is NOT about creation of PDFs from paper, and NOT about OCR of paper scanned documents to PDF. 

 

We receive very large PDF files that have not been OCR'd so we use "Tools, Scan & OCR" to make them searchable but it can be very slow on large files.

 

I have read that Adobe Acrobat Pro is not memory bound, (i.e., that the more memory you have, the more it can use).  Does this translate into better performance for Optical Character Recognition (OCR) of PDF files?

 

Some have pointed to 'specialty OCR packages' as an alternative but we don't want that. We want *fast* OCR and *fast* searching of PDF files using Adobe Acrobat Pro running on the right Apple hardware.

 

Has anyone bechmark tested Apple M1 Pro processor with 64 Gb on a Macbook Pro vs Intel Xeon W on Mac Pro 2019 with 128 Gb or 256 Gb or RAM, for example?  Are there specs on differenes in memory optmization?

    Yes there are different specs, and I wouldn't look at it from the memory optimization standpoint alone.

     

    In order to benchmark appropriately, if you intend to test this scenario with two completely different hardware platforms, the operating system must also be the same in both computers, and you will also need to test with the same Adobe Acrobat Pro and the same OCR software versions.

     

    Not because M1 was designed to integrate well with newest macOS versions, it necessarily means that a brand new  M1 processor will proove to be as efficient with only 64 GB of  Mac memory (RAM) when benchmarked against the performance of an older Intel processor (like Xeon W) fueled with twice the amount of RAM ( or more).

     

    That said, how many GHz and how much megabytes of cache has the Xeon W that you intend to benchmark with?

     

    Also, what Intel graphics does it supports? and how many cores does it have?

     

    Moreover, the operating system will also play a major role in allocating resources.

     

    In which case,  if the MacBook Pro with the M1 chip that you're referring to has everything soldered onto the mother board, then you will not be able to upgrade RAM, and therefore, your benchmarking will be very limited.

     

    If this would be the case, then just downgrade the RAM of the  Mac Pro computer to 64 GB and see how it behaves in contrast with the MacBook Pro that have the M1 chip with 64 GB of RAM.

    Thanks but I don't want to benchmark anything.  I want to get information.
