I don’t have any information specifically on iflex, however I can give you some data points on the scalability of single task workloads with our latest generation server processor.
While the Xeon 5500 is a quad-core processor, it does a great job computing single thread workloads since the OS can turn cores off and boost frequency (if needed) and has very high platform bandwidth to feed the processor due to an integrated memory controller coupled with intel quickpath technology, pci express gen 2 and ddr3 memory.
The Xeon 5500 has top scores in SPEC’s single task (SPEED) benchmark suite based on best published data (www.spec.org as of march 30 2009) and at http://www.intel.com/performance/server/xeon/server_table.htm
Xeon X5570 quad core
Xeon X5470 quad core
Xeon 5160 dual core
Xeon 3.8 single core
For a Financial Services Application (Sunguard), the Xeon 5500 beat out the previous Xeon 5400 by 38% (source intel measured data)
Hope that helps, Chris
How does the i7 series stack up to the Xeon 5500 for single threaded mathematically intensive (Markov Chain Monte Carlo) I/O bound applications where only a single instance of the application will be running? Do you have any recommendations on improving performance in these types of I/O bound secenarios?
