Branch predicting != OoOE and sometimes you have to have lots of branches, if theres enough branches in program even old Xbox would perform better than CELL. Theres also problems with memory in CELL approach. SPEs have way too small memory for some tasks. For example 50MB chunk in memory with random depencies into other points of that 50MB chunk. You would have to use main mem only and that would make processing quite slow. And about that blind eye. Show me one link that shows that its better in general purpose stuff than PCs today. If you run only simple instructions/integer stuff, CELL wouldn't beat even 3-4 years old average computers and if you put some branches there it would render even slower. Well, as there seem to be title war. I am going to be master of science in computer science in year or two. (Btw, first program is available. For linux & windows. Check sig, ty. ^^) |
That's not true, IF the programmer use the branch hints PROPERLY. If they don't, you would be right. However, that would be the programmer's fault and not the processor, because the processor is capable with proper effort.
Don't ask me to provide the links AGAIN, when I went through the trouble of putting them all in one place (one to two pages back). Just look at the multiple purposes (by definition that's general) that were demonstrated.
What's this about a title war? BTW, Mike Acton, from Insomniac, tells you to UNlearn what they taught you in school. He says the UNlearning process is what makes parallelizing your code for the Cell hard. Have you UNlearned your old practices today? ;)
