To be honest, number crunching on a GPU is better than a CPU, since GPUs were designed to number crunch. Look at the newer CUDA and ATI GPU cards. They have 32, 64, 128, 512, or more "cores" or "streams". There is a movement to create systems that are GPU based instead of CPU based. The gaming systems are almost all GPU based, since they do not need to run traditional packages that a "home" or business computer needs to work with. Well, the Excel vs. Calc speed comparison on the same system [32-bit] is a different "thing" than making a 64-bit version of LO or a GPU based LO package. The difference between Calc and Excel may be the efficiency of the coding. There are still a lot of old legacy code in LO that is being worked on to make it work better and much more efficient. Just saying we need to create a 64-bit version of LO to fix the "speed issues" is not really solving that issue. As for making LO work with a GPU card, well I would not be surprised that not too long from now, both Windows and Linux will have a version that is GPU based. That is one of the things that would make our current systems faster without replacing the motherboard or CPU. Just buy a newer, faster, GPU for the system. This is what the gamers do currently. The price of these faster GPUs are going down. For $100, I could buy a GPU 3 to 4 time faster than one I could buy 2 or 3 years ago. The GPU speeds per price is a much better "ratio" than the CPU speed per price. You just get more speed or number crunching power for you money with a GPU card, compared to the CPU/motherboard costs. -- To unsubscribe e-mail to: [email protected] Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
