Default OK, now I'm miffed

Overall, AMD Athlon XP processors are able to perform 9 operations per clock cycle while Intel can only manage 6.

AMD cpus (athlon 32 bit) perform 9 operations (units of actual work)
Intel cpus (P2-3, older P4 and newer P4 while not in a hyperthreading state) only do 6 operations per clock cycle...

so you do the math...

*opcc = operations per clock cycle
*ops = operations per second
EDITED FOR ACCURACY
(AMD) 9 opcc multiplied by 2000 (2ghz) x 1,000,000 = 18,000,000,000 ops (eighteen billion)
(INTEL) 6 opcc multiplied by 3000 (3ghz) x 1,000,000 = 18,000,000,000 ops

realistically, the exact same amount of real world work, regardless of overrated megaherts hype....

The athlon does 9 operations per cycle ... how many does the p4 do??? Yes that's right ... only 6. Pretty poor show really.

AMD Athlon CPU make up its disadvantage in memory bandwidth by providing three Full x86 decoders (while Pentium 4 has only 1) and performing 9 operations per clock cycle (while the Pentium 4 has 4). Consider the much more expense on the latter system, we still believe the former one is worth to report here.

Also, the Athlons perform 9 operations per clock cycle, compared to 6 for the P4 (non HT).

AMD Athlon XP 2800+ (2.083Ghz) (Inc fan/heatsink) (OEM)

# Frequency 2.083 GHz
# Cache Size: L1 - 128KB and L2 - 512KB
# Die Size: 128mm2
# Transistor count: 37.5 million
# Infrastructure: Socket A
# QuantiSpeed™ Architecture
# 9 Operations per clock cycle

Intel's do 6 operations per clock, AMD's do 9 operations per clock.

Simply put, AMD's do more calculations, and have less bottlenecks when gaming.

I could write you a book about it, but I'd just be quoting AMD...and even I would get lost in the technical explanation.

So AMDs or Intels?
Let me out an example of the XP 3200. It only goes up to 2.2ghz. On the other hand the P4 goes up to 3.2ghz and over. *ok more ghz, im happy*.
Unforuntely, no. the Intel does only 6 floating points per cycle meaning that it can only carry out 6 operations per cycle. The AMD does 3 more so it can do 9 points.

Maths Lession:
3.2ghz x 6 = 19.2 (Intel)
2.2ghz x 9 = 19.8 (AMD)

OK, Praetor, now how precisely can you call this bullshit? Obviously something's amiss, because I couldn't find one shred of credible information that even remotely refuted my statement. In fact, it would seem that there is an overwhelming tendency to agree with my statements. By all means, you may ask for my sources of information, but before you call my words "crap" and/or "BS," at least confirm that they are "crap," and/or "BS."
