how do you figure out the speed of amd

[davidjaii]

i have a a64 3000 . It says 200 htt x 10 multiplier = 2000. how does 2000 = 3g speed

 

[biostud]

it's similar to a Intel p4 3 Ghz, AMD processors are more efficient pr. mhz than p4, so they name them after the similar Intel processor.

 

[davidjaii]

so what would a 2100 core speed = intel speed ?

It's not comparable like that actually. AMD and Intel processors have different architectures. One performs better than the other in one area, and worse in another.


Benchmarks are your friend.

Look at the specs or if you already own the chip then just run something like CPU-Z

Hi guys,

I though I've read somewhere there's some kind of multiplier that you can use to get a rough estimate of how fast an AMD chip is compared to an Intel chip. I think it was 1.7xx or 1.5xx.

I can't remember for sure. But you multiply the amd clock speed by the multiplier and it's supposed to give you what the Intel speed would be.

Anyone ever hear of this??

How about using AMD's own naming scheme? A 3000+ chip is equal to a P4 3.0GHz chip...AMD chips execute more instructions per clock cycle, thus get more work done, thus require fewer GHz than a P4 to do the same task. KindaSorta ;o)

Nope, no such direct comparison does, or can exist.

Some AMD chips are faster than others at given clock speeds. Some AMD chips are faster than others with identical ratings. Equally some P4 chips are faster than others at given clock speeds.

To top it all off, the difference varies according to the benchmark. AMD tends to do better in games, Intel in media applications.

There's no direct correlation - as other people have said, benchmarks are you friend.

Oh, and AMDs scheme is based on a Athlon XP Thunderbird running at the same clock, not a P4.

Modern AMD CPU's process 9 instructions per cycle, while pentiums only carry out 6 instructions per cycle. So:

(2GHz Athlon64): 2000 Mhz x 9 = 18,000 Million instructions per second (MIPS)
(3GHz Pentium4): 3000 Mhz x 6 = 18,000 MIPS

So a 2GHz athlon is basically equal to a 3GHz pentium. There are other factors (such a memory controllers, cache, etc...) that affect performance, but the instructions-per-cycle is the main difference.

Hi, The best way I have found is to go to sites that sell the processors. Most will list the name of the processor followed by their actual clock speed. Luck, Jim

 

[supastar1568]

a 3000+ is equal to a Pentium 4 3.00Ghz . Well obviously NOT EQUAL to, but in the same "class" per say.

Its probably so consumers dont go buying a P4 3.0Ghz over a Athlon 3500+ because they think the more GHz the better.

Oh, Lord...

First of all, it may help to look at a few things....

Celeron D 345 (3.06 GHz, 28KB L1, 256KB L2, 133 MHz FSB, LGA775)
Celeron D 346 (3.06 GHz, 28KB L1, 256KB L2, 133 MHz FSB, LGA775, 64-bit)
Pentium 4 3.06 GHz (20KB L1, 512KB L2, 133 MHz FSB)
Pentium 4 3.00 GHz (20KB L1, 512KB L2, 200 MHz FSB)
Pentium 4 3.00 GHz (28KB L1, 1MB L2, 200 MHz FSB, s478)
Pentium 4 530J (3.00 GHz, 28 KB L1, 1MB L2, 200 MHz FSB, LGA775)
Pentium 4 531 (3.00 GHz, 28 KB L1, 1MB L2, 200 MHz FSB, LGA775, 64-bit)
Pentium 4 630 (3.00 GHz, 28 KB L1, 2MB L2, 200 MHz FSB, LGA775, 64-bit)

And that's not even a complete list. How can an A64 3000+ be comparable to a P4 3.0 when a P4 3.0 isn't comparable to a P4 3.0?

i think zebo determined tat it was amd *1.57= intel but i maybe wrong.

[/quote]In terms of raw power (based on clock speed):

Intel = (AMD*9)/6 = 1.5 * AMD

But other factors such as Cache, FSB etc... will make a difference in real-world applications. So so an AMD*1.57 may be equal to an Intel in gaming, but I'm sure that in video editing it would be a different story.

Excellent point.
