Sorry, what I meant was that Morphos without JIT is equal in speed to UAE with JIT on a MHz for Mhz basis, meaning that a 1Ghz Pegasos would be as fast as my 1Ghz PC?
First, you must understand that speed is dependant on many things beyond just MHz. As a member of the amiga community you must realize this. A 40Mhz 040 based A4000 will smoke any 40Mhz 486 system. Unfortunately, in today's world this is further complicated beyond simple differences in the CPU.
My 600Mhz/G3 Pegasos smokes my 950Mhz Celeron PC for *most* tasks. When running Amithlon (w/JIT) against my non-JIT install of MorphOS (same PC, just amithlon instead of windows) the speeds are comparable in most instances, with one or the other getting the nod of better performance depending on what I'm doing. Unfortunately, my mileage may not match with your mileage.
The reason? Speed isn't about MHz anymore. You have memory speed, bus speed, harddrive speed, the graphics card speed, and all of that before getting into the CPU's cache sizes, which can make a world of difference depending on the application. (Try encoding a video on a 1ghz celeron vs a 1ghz PIII. Remember, they ARE the same CPU with different cache sizes.)
Thus, it becomes very difficult to make any blanket statements. With that said, UAE has to sit on a host OS (windows, linux, etc), so it has some drawbacks right out of the gate. However, in the end, it will still depend on who built the system, how careful they were with selecting parts, etc. I have seen 1Ghz PIII's outperform 1.7 Ghz P4's due to the configuration of the other parts in the system. In the end, my earlier statement stands. Visit the AmiGOD2 statistics site if you want to see test results.
