news 28 Posted April 30, 2013 When GPU computing came on the scene it was full of great promise. The idea of a heavily parallel processing unit that will accelerate both integer and floating point workloads could be a potential gold mine in wide variety of applications. Alas, the promise of the technology did not meet expectations when we have viewed the results so far.

A dedicated GPU will have its own attached memory as well as shared memory with the main CPU. Due to the communication latency issues of writing from main memory to the video cardÂ’s memory, it is not nearly as seamless as what an APU can accomplish. It makes sense that such a setup would benefit a solution with a shared memory pool as well as a shared memory controller. Everything else involves more latency and differing amounts and types of memory." Thanks for a post! Ryan Shrout PC Perspective rshrout ( -at -) pcper.com Share this post Link to post
