This is the main reason that you can't simply compare "core count" between AMD and NVidia GPUs to estimate their relative performance. AMD has more cores that can significantly speed up some calculations but are less flexible.NVidia has fewer cores but they are capable of more complex tasks than the AMD cores.The product lines of AMD and NVidia still have significant differences in architecture, the most distinctive difference is this:
These are different than the "cores" in the main processing chip - but the more the better. On the graphic card description you can read something to the effect has 512 streamprocessors, has 4096 streaming cores or what ever. I really did not want to get into a big technical discussion, because its not really germane. Just a note about what interested_observer said, number of 'cores' aren't meant to be compared between different manufactures for both cpu and graphics card.Thanks for keeping me honest. Their performance characteristics are a bit different but in general it's no big deal. That said, my 5 year old $500 desktop is still good enough.Īges ago there used to be some compatibility issues, nowadays it is non-existent. I have done this 3 times now with boxes from Costco over the years.Ībout 18 months ago, my son built a nearly no holds barred system for about $900 (took advantage of all the Black Friday and Christmas Holiday sales and discounts). The graphics cards will be the lower tier that will fit within the OEM power supply spec. You can drop in a graphics card (OpenCL), however the OEM power supply in the box will limit your selection. One note - Most of these boxes use the on chip graphics processor. You might not get the absolute optimum setup, but it should be close enough for the price. eSATA interfaces have a high transfer rate (near PCIe bus rates).Īll in all, you can go into a large box store (Best Buy, Costco, etc.) and find pretty much what you are looking for at a $500 price point. The faster the disk spins, the quicker you can get to your data. Get at least 1TB, and look for the rotational speed. Storage - Yes SSD is the fastest, however spinning media (disks) are still the cheapest (and fast enough).Graphic Cards - 1) Get OpenCL compatible, 2) more cores the better, 3) more graphics memory the better.
