Confused about Pentium4

[yo2tup]

When looking at the architecture it looks as if intel forgot the FPU on the processor and put everything in ALU, and that's what people usually attack. but in benchmarks or whatever, it says that the pentium4 is actually good in FPU but is really bad in interger? i dont get it

Pentium 4 is extremely powerful in FPU with SSE/2 compiled code. If the code is x87, P4 will suck.

Basically, the x87 FPU architecture is cumbersome and outdated. Intel seems to want to replace it with SSE.

Unfortunately, this hurts performance in todays apps as well as legacy apps.
