- I wonder where you got that information from...
-
-
- As far as I can see and as far as you can trust benchmarks (where I
- rate SPEC as one of the more reliable ones) the processors are about
- equally fast. (Note that the SPEC numbers for the 604 is the highest
- reported so far and that they fall below the estimated 200/200
- (SPECint/fp-92)). See the table below:
-
- *******************************************************************
- Processor Clock (MHz) SPEC-92 SPEC-95 Note
- int fp int fp
- M68040 25 21 15 (0)
- M68060 50 ~60 ~45 (0)
- Pentium 133 191 121 4.1 3.1 (1)
- Pentium Pro (P6) 150 276 200 6.1 5.4 (2)
- Pentium Pro (P6) 200 366 283 8.1 6.7 (2)
- PPC 604 133 176 157 4.1 3.3 (3)
-
-
- (0) Just for comparison. The 060 performance is estimated to be ~3
- times faster than the 040 (there are no actual SPEC numbers reported
- for the 060 that I know of).
-
- (1) Pentium is available at 66, 75, 90, 100, 120, 133, 150 and 166
- MHz. The last three are all faster than the PPC 604.
-
- (2) Pentium Pro is available in these two versions today.
-
- (3) This is the fastest available PPC today. There is a 150 MHz 604e
- coming up, expected to give 250 SPECint-92, but it isn't here yet.

-
- So what they did was comparing one "top of the line" PC (I wonder what
- they considered was "top of the line"), probably running Windows or
- Win95, and one PowerMac running System 7.5 or some such. Now, what
- conclusions could you make about processor performance from such a
- test? The answer is *none*.
-
- > The P6 is not showed to be a major leap forward at all ...
-
- No, it isn't but it is still more than twice as fast as *any* existing
- PPC today (see table above).

-
- They will probably not have such an advantage (they don't have it now)
- but they will probably have a (much) better price/performance ratio
- even if Intel probably could lower their prices significantly if they
- felt like they need to.
