Actual AMD speed

I've heard that an AMD 3400+ is comparable to an Intel 3.4Ghz. Now is this true? If you ran a benchmark for a cpu, would they come out pretty much comparable or would the AMD 3400+ be slower than the Intel 3.4Ghz?

Now i know you going to say, what type of AMD or what type of Intel, but im not quite sure if the Atlon XP or Athlon 64 is comparable to a P4, so just tell me if thats pretty much how to tell the speed of an AMD to a Intel.

Thanks
 
3400+/3000+/whatever+ wasn't supposed to be the Intel speed equivalent (according to AMD) but it tends to work that way. It's a rough comparison that is close enough.
 
So if i were trying to compare an AMD with an Intel, i should look at the number before the +, not the actual operating frequency. And i have another question, what the difference between all the cores? (Venice, winchester, etc.)?
 
Yeah

The frequency is not the main performance indicator. In fact, AMD can accomplish more work per clock cycle. Therefore there is no such need for high frequencies like that seen in Intel processors. Rouhly said, the 3000+ rating for example is about the speed of a Pentium 4 3Ghz (although AMD does not claim that is the intent). The difference between the cores is often the Vcore requirement (1.4 for Venice and more for Winchester) and the on-die memory controller which is better in the Venice than in the Winchester allowing for all four banks to be occupied and still work at 400Mhz (Although at 2T command rate).

Yes

It can get overclocked well (look at my sig). The Venice/San Diego cores also have SSE3 support as well.

So, theoretically, a 3.2 pentium is about as fast as a 2.13g amd? Im not sure I did that math right.

That would be between a 3200+ and a 3400+.

The price difference there is not that large. (between the pentium and the amd's)

Not... The AMS 3400+ socket 939 Venice is faster than a Pentium 4 3.2.

Amd 3400 runs at 2.2Ghz. The 3.2Ghz processor runs at 3.2Ghz. I hardly consider the AMD being faster.

Operations per clock cycle:

AMD: - 9
Intel: - 6

looked it up on several websites

1. It depends on the OPcalls being made
2. Many, if not most of the opcalls usually take 2-5 cycles to execute. The ones that take 1 cycle for execution ... they arent common (although more common on K8s than on Pentium4's interpretation of ASM)
3. Just looking at plain numbers like that doesnt take into account branch predictor efficiencies or cache hits
