I asked a former instructor about the Sparc processor and he said the following: "The Sparc processors are able to due a high-level of multi-threaded tasks simultaneously. If you have an application that requires this such as a web server or database server, the ability of running a 64 threads simultaneously is awesome. However, if you do not have the need to process that many threads simultaneously, the cost of the Sparc system is not worth it. Intel and AMD have made huge strides in the past 10 years and their processors do an amazing job. For most applications, one of the AMD or Intel multi-core systems will do the job. If you are using one server to do e-mail, web, database, file-sharing, etc., then an Intel or AMD system is probably the better choice since the required code is so different. I believe Sparc processors are typically socket type processors, but usually you cannot upgrade them like a PC. The motherboard is only designed to handle a certain chip or maybe a few chips of very similar capabilities." It's still not clear if the Sparc is socket based or embedded though and what they mean that the process are still not upgradeable like Intel and AMD processors. The only stuff about the 8 threads per core for a total of 64 threads simultaneously or more does though or at least it should and compared to Intel 2 threads per core that would be awesome if I had a need for it, but I probably don't. Also how does this compare to AMD's hyper-transport, which if I'm not mistaken is the equivalent of Intel's hyper-threading. What do the Sparc processors look like especially the current ones and if they are available seperately how much do they cost and where can I purchase them besides from Oracle? I currently have a dual processor Xeon E5 2600 v2 series system as my server for live testing of network configurations, so why would I need a system that uses a Sparc processor(s))? At the most even a Xeon E3 system may suit my need, but I choose the E5 because I had other plans as well, such as folding at least if not OpenCL or DirectCompute or anything in that neighborhood.
