i want to see AMD-64 come up against the Itanium 2 design.
What does it have to do with the opteron-xeon topic......?
addresing yoiur question, exactly how.....? An itanium 2 box will beat an opteron is single and dual configurations with
properly compiled software..... for 4 and 8 way machines, I wouldn't be that sure..... not to mention the huge difference in price.
because people keep playing "AMD will take the lead for 64-bit" card, and that doesnt apply in the server arena because thats where the Itanium is marketed. Intel specifically markets the chip for high end servers and even says on their own website that Itanium is better than Xeon for high end servers, offering a 30-40% performance increase for a 10% increase in cost.
Opertron 148 - 1405 Int 1393 FPU
Itanium 2 1.5ghz 6MB L2 - 1332 Int 2119 FPU
Are those figures for a 4 way machine or a single CPU one? As I posted, in a single CPU the itanium will be faster with very properly compiled software..... give me the score for a 4 way or 8 way machine versus a comparable opteron and I will believe it.
If you think that an architecture that NEEDS a chipset sharing a FSB with all the CPUs AND managing the memory can scale better than one with integrated memory controller per CPU AND dedicated paths to inteconnect the CPUs, then you need to revisit your concepts. For medium and high end servers, the bottleneck is data transfer.
Regarding the SPEc results, even if the FP number of the itanium is higher, most of the database/SQL or related server applications benefit more from INTEGER performance, right?
Do you have any numbers on 4 way or higher configurations for REAL server applications?
"For medium and high end servers, the bottleneck is data transfer" Do you think it is coincidence that what will be the most powerful supercomputer is based on Opteron?
Keep in mind that the compilers for AMD can only get better.....
