Hello to all.

It's been 10 years since the introduction of LGA775 and that question still remains.
But don't worry guys, I'm here to answer it once and for all.

Answer will be interesting.
But first, introduction to those that doesn't know what CPU(s) are valid - since LGA775 is so old and has SOOO many CPU's to choose from.

I tried to make introduction a two point-view problem, that will be in form of conversation between two "geeks" and Me as starter.
Hope it will be interesting to read :)
--------------------------------------------------------------------------------------
agent_x007 : So, what would be Your pick for fastest LGA775 CPU ?

Geek "A" : Well best non-OC CPU for LGA775 would be 57x/67x Pentium 4 (depending on cache usage by program we test) or Pentium 4 Extreme Edition (if memory bandwidth is bottleneck). Simple, right ?

agent_x007 : Oh I forgot to mention - I'm not talking about fastest, without overclocking them.

Geek "A" : What, why ?

agent_x007 : Because that would be boring :p
What's the point of platform that can overclock any CPU, when U don't want to use it in this kind of problem ?!
So, with OC in mind, once again :
What would be Your pick for fastest Single-core in LGA775 world ?

Geek "A" : OK, fair point. But I still think Pentium 4 would be a good choice especially with HT enabled. It certainly has got frequency to backed that claim.

Geek "B" : But everyone knows that it's hot and end performance is really poor.

"A" : Oh, so U got better idea ?

"B" : As the matter of fact I think I do...
Don't know if U guys knew, but there was a Conroe based Celeron with active only one core - Celeron 4xx family.
And fastest chip from it is Celeron 450. It must be the fastest !
It's based on "Conroe" ie. "Core" architecture, and everyone knows that they can overclock 40% easily.

A : Well... not exacly. Because that still is "a Celeron".
And all Celeron's are robbed of everything expensive before they go on sale.
In case of Celeron 450, Intel took 7 out of 8 parts of it's original cache.
That's going down from 4MB cache in Conroe (Core 2 Duo) to tiny 512kB in Conroe-L (Celeron 4xx). That must HURT it's performance big time.

B : Still, that leaves overclocking and A LOT better architecture bottom line.
It will suffice.
What can possibly Pentium 4 HT have that Conroe based CPU can't ?!

A : Well that would be frequency :)
Pentium 4's are hot yes, but before Netburst "died" Intel released best incarnation of it on market.
Name is Pentium 4 and model is 651.
Oh yes... Cedar Mill in D0 revision.

B : "D0" ? Isn't that the same version that got to 8GHz+ about a year ago ?

A : Yup :cool:

B : I'm OK then :)

A : How so ?

B : That chip was cooled by LN2 and it was a Celeron D 360, !

A : In Pentium 4 651 it's the full version, 2MB L2 + HT so it won't need LN2 to get skyhigh performance :P

B : But still, "Core" architecture rules in LGA775 - everyone knows that.
So what if Pentium 4's got faster clocks, that Celeron after OC can do more in one clock that even the fastest Pentium 4 !

A : Wonna bet ?

B : OK, we got ourselves a competition now.
----------------------------------------------------------------------------------------------
End of introduction.
Hope I didn't messed up too much in this "English" language :D

So, since Overclocking is "allowed" what U guys think, who/what would win ?
Geek A's "Brute-force" approach in form of Pentium 4 651, or
Geek B's Celeron 450 based on superior "Core" architecture ?
Or maybe someone's got different opinion about fastest LGA775 CPU after OC ?

For now it's really late for me and I need to go to bed -_-
So it will be "few" hours before writting answer.
At least now, U got time to think and pick your CPU ;)
Cheers to all.

"Fast link" to result part : LINK

SOOO, the results part :)

First off, test platform :
Well, since I want to know what's which CPU is faster i need a good GPU...
GTX 780 Ti laying there should be good enough :p

Next up, motherboard...
Well there are no PCI-e 3.0 one's, but in theory PCI-e 1.1 should work with 3.0 card.
Let's try a cheap board and see.
After few minutes...
It works !
OK, we got motherboard.
ASUS P5B rev. 1.04G (P5B "Vannila")

CPU Cooling ?
Let's go with Air cooler with "enough" Heatpipes.
SPC "Fortis" HE1225 it is then.

Last but not least :
3GB of 800MHz CL4 DDR2 memory, check.
And Corsair TX750 (v1) PSU, check.

OK, we got all nessessary things.
We only need programs to test performance.
Well, since all CPUs are overclocked let's go with 3DMark benchmarks.
It's not like GPU is going to be a problem ;)

But which versions...
Hmm, how about all of them ?
OK :p, so first test is 3DMark...
Whoops !
Forgot to write OC settings for CPU's
I'm getting old...

Here they are [Ekhem...] :
In Red corner, overclocked to amazing ~4,9GHz and still cooler than most things today at that speed, u guess it, it's one and only Pentium 4 651 ! : LINK
And in Blue corner, overclocked by whooping 44% (or to 3,17GHz) and still using less power than Pentium 4 at stock, "eco OC" Celeron 4-50 ! : LINK

Since that's done, moving on to benchmarks.

3DMark03 :
Pentium 4 651 4,9GHz : 37644pkt. (LINK)
Celeron 450 3,17GHz : 33582pkt. (LINK)

3DMark05 :
Pentium 4 651 4,9GHz : 10086pkt. (LINK)
Celeron 450 3,17GHz : 8972pkt. (LINK)

3DMark06 :
Pentium 4 651 4,9GHz : 7484pkt. (LINK)
Celeron 450 3,17GHz : 6534pkt. (LINK)

3DMark Vantage :
Pentium 4 651 4,9GHz : P7509 (LINK), X11912(LINK)
Celeron 450 3,17GHz : P6175 (LINK), X9381(LINK)

3DMark11 :
Pentium 4 651 4,9GHz : P2936(LINK), X2777 (LINK)
Celeron 450 3,17GHz : P2327 (LINK), X2356 (LINK)

3DMark (2013) :
Pentium 4 651 4,9GHz : Fire Strike : 2679; Could Gate : 3496; Ice Storm : 31608 (LINK)
Celeron 450 3,17GHz : Fire Strike : 2544; Cloud Gate 3261; Ice Storm : 27384 (LINK)

OK, and we have a winner !
Best and overclocked, single core, CPU in LGA775 socket is Pen...

Geek "B" : HOOOOLD IT !!!
agent_x007 : What ?! Why ?
Geek "B" : U can't do that
agent_x007 : Again, why ?
"B" : U didn't overclocked Celeron 450 to it's limit !
agent_x007 : That's true, but it woudn't make a diffrence.
"B" : What, how so ?!
agent_x007 : Well, when I was overclocking it, 300MHz FSB wasn't stable (that's 3,3GHz) and 333MHz FSB didn't even show POST. So I decided to drop FSB a bit, to even it out with Penium 4's (it's fair, since now they can use same RAM settings).
"B" : U probably just got s**tty one.
agent_x007 : Well maybe, but bear in mind that this CPU is lowest end of Conroe. Basicly : They are the worst chip's Intel produced. So I really don't think they will EVER overclock as well as full fledged Core 2 Duo's or Pentium Dual-Core's will. Satisfied ?
"B" : Kinda...
U still didn't tested them in games, so it's not TRUE test.
agent_x007 : ...OK, let me try this again.

[Breathe]
Best, Single Cored CPU after OC, using LGA775 socket is... PROBABLY Pentium 4 "Cedar Mill" - D0 rev.

Oh, and best Single Core non-LGA775 CPU, without OC, is either AMD FX57 or Xeon L3014.

[Whisper]
agent_x007 : Happy ?
"B" : Yeah, but...
