Does This Mean...?

I was comparing the two following processors:

Now it looks like the Atom D525 at 1.80GHz is better than the Intel Pentium 4 at 3.00GHz...but does this mean the first one is better overall, or is it possible the second one outperforms it in some way? For instance, which is better at single-tasking? And why is the Atom "1.80" whereas the Pentium is "3.00" and yet the Atom is better? From what I've heard, this Atom processor is good at "multi-threading", so maybe that is why it is rated higher? I would like to know how I can find out if the Atom is better at doing a single task.

I wish I can find specifics on this, but the CPU Benchmark site just simply says where processors "rank".

quite simply, since the advent of multi-cored cpus the speeds should no longer be based on the clock speed alone, the die size is just as important (smaller die sizes are faster than same clock of bigger scales in most instances) along with age of the tech inside... hence a Atom 1.8 can trounce a 3.0 pentium, and likely a dual or quad core cpu would eclipse them both to a huge amount even at 1.5ghz speeds.

Atom D525 1.8 Ghz has 2 cores hyperthreading --> 4 HT threads total. 2 HT cores ~ 2.4 real cores.
Pentium 4 3Ghz --> not sure, is this single or dual core?

Intel Atom D525

Atom is probably a little faster and better handles multitasking. But even more important is that Atom's TDP is way lower than Pentium 4's. I would choose Atom. : )

I suppose the other thing is that Atoms are mainly aimed at the laptop market, so the biggest rivial to them will be the Core Duo and i5

True, Pentium 4 3Ghz is usually a desktop pc. Atoms are mainly aimed at netbooks.

could just about cook eggs on my old pentium 4 (3ghz) prescott... even the newer "D" multicore edition were cooler

Oh you came thro that too? My Pentium 4 530J (Prescott) was never colder than 65 C.

Yea, i think if I recall correct I started on P75/P90 Pentium1, then jumped to Intel 166, Intel 333, AMD 500, Intel Pentium3 800 then leaped to AMD with 1300 AMD Thunderbird (went through two in a space of three weeks that melted!!) jumped back to Intel a few weeks after to the P4-1800 then P4 3000 Prescott which thus far has been hottest CPU even compared to my current Intel quad, the Q6600 2400, even when overlocked to 3.6ghz!!!

if ya read my new blog you'll see I rebuilt my rig today, currently the coldest i've seen my chip go on air, lowest core is sat at 24C with 21C ambient air in my room

Ya, I envy your case, very nicely designed. : )

Can't believe those temps are due to Zalman 9700? Mine is Zalman 9500 and the CPU (Q9450 @2,93 Ghz) is never cooler than 50C with 21 ambient in the room. : (

Well was your idle or at max load though? here's a grab after running prime95 x64 for an hour at 100% load on all cores I run earlier, after ended the test it drop to sub 30C on all core in about 3 seconds!
