amd vs pentium 4

[nguyen1025]

why does my friends amd 64 3500+ (2.2 ghz) feel as fast or as faster as my pentium 4 3.0 ghz with the same amount of ram when its lacking amost one whole ghz behind?

Are you being serious?

if it holds up to its rating (which they do in benchmarks) it should be faster than a 3.4 P4. This is becuase of higher IPC (intructions/clock cycle) of the AMD. This has been answered many times on this forum. You appear to be new, so I am giving you a break. There is a search button that helps a lot.

Totaly differant architecture. The pentium 4 was designed around increasing the clockspeed by using longer pipelines, while the A64 uses shorter pipelines that are wider. You can't compare them by just the clock speed, it's like comparing apples to oranges. An A64 3500+ will pretty much blow away most Intel CPU's in most applications.

And it gets worse for each 200mghrtz increment increase in processor frequency because each 200mghrtz at 9 instructions per tick gives and 12 pipes give you better performance at 6 instructions per tick and 31 pipes (or whatever insane amount it is)

Just take your AMD64 and multiply its actual frequency by around 1.5 to give you an approximation of the Intel counterpart (simplistic but true enough)

2600 FX-55 equates around 3900 EE.
2200 3500+ equates to 3300 PIV.

You can see the increase in frequency favors AMD at equal measure. This is all approximates. If you took gaming the 3500+ is faster than every Intel process (except maybe the 3.73 EE) while it would be slower in heavier multitasking or video editing than a 3.4Ghrtz Prescott/Northwood

Mhz doesnt mean anything anymore. It's only use is compairing processors of the same family against eachother.

Well, there you go.

Aslo, AMD is a brand, and Pentium is a processor. You speak of Athlon 64;

Athlon 64 has the best price/performance ratio than any other desktop processor in the market. You should look at the ratings instead of the speed when checking performance on the processor.

a 3500+ is the equivalent of a pentium 3.5 ghz

thread necromancy, why? 😕

i have notice in some things a 3.0 p4 is faster than a 3400+, like in multitasking (when there are 3 different games or large applications, the p4 will blow the a64 away) but in games, they give higher frame rates. however, i don't really notice a difference in speed and performance, they seem to be the same. a64 x2 > anything basically.
