Dhrystone ALU: 4970 MIPS
Those are NOT FL

perations Per S
econd. They're Generic Instructions thus stress, and benchmark, a whole
different part of the CPU that has nothing to do with FLOPS. CPU's are mainly designed to process generic instructions, which is why you see
processors such as Cell blow away Desktop PC's in specific kinds of instructions such as Floating Point. Cracks me up... Cell is only an in-order
processor, which means half the processor will be at idle even if it is at, so called, '100%'.
Whetstone FPU: 1443 MFLOPS
Those Floating Point Instructions stress the Floating Point Unit.
Whetstone iSSE2: 2652 MFLOPS
Those are SSE2 instructions which are yet again, different to the above.
If you want the true total, you have to add all the FLOPS that stress different parts of the core together to get a closer value. However, in reality
it can be difficult to acheive that, because more often than not, you'll run into bottleneck in the bus, memory, schedulers, or cache. Those numbers
are theoretical only, or under very special circumstances.
By the way, FX-57 and Pentium 4 are old hat. My processor.... Dhrystone ALU: 55403
MIPS... 11 times as fast. Once I get my new cooler, it will
be 25% faster. That was with a newer Sandra which didn't have SSE2 test.
Link to 2005 version?
