Re: Brookdale (i845) disappoints with DDR SDRAM SPEC with the Intel compiler, especially since Intel gained control over detailing the algorithms and data sizes used, is little more than a utility for checking the number of memory channels and their frequency - it's almost totally useless as an indicator of real world processor performance. I know I'll be quite surprised if most real benchmarks don't show DDR P4 performing at least as well as RDRAM P4. DDR P4 is probably going to be a good combination for Intel, despite the bogus Intel SPEC scores. It will have good performance and low cost.

Andreas: Brookdale (i845) disappoints with DDR SDRAM (c't) (SPEC scores) One of the major advantages of SDRAM over DRDRAM is latency. This is a really important feature in real applications. It's easy to see if you compare 100MHz CAS2 SDRAM with 133MHz CAS3 SDRAM. The 100MHz SDRAM actually provides the better performance in most benchmarks (although they are close, it should be said). With SPEC, memory latency virtually doesn't matter - only bandwidth. So, basically what you have with SPEC is a worst case scenario for i845 vs i850. In other words, i845 with DDR SDRAM could still perform exceedingly well and I most certainly wouldn't discount it based solely on SPEC numbers. -fyo
