hey all,

I have been readuing about the new i7s coming out and i was wondering how are they differnt from the C2Qs and the old i7 chips.

The things i know about are:

New sockets LGA 775 > LGA 1366 > LGA 1156/ 1366

Hexa cores

I also read that C2Qs are not really "quad cores" that they are fake and the i7s are "real quad cores" is this true and could you please clear this up?

Thanks for any replies.

1366 has a higher IPC than 1156 i7, and 1156 i7 has a higher IPC than C2Q.

the Core 2's aren't real quads because they are two dual core CPU's stuck together.

C2Q have 4 core.
EX : the Q9650 is a "dual" E8400 ...

If not, C2D arnt DUAL ? ... C2Q are QUAD and C2D are DUAL ...

I7 just have 4 real core. Its a new architecture. Like its been told. I7>C2Q Clock for clock. They can do more work per clock.

Edit : ++ the I7 are really better for Multi GPU !

So 2 + 2 no longer equals 4 :heink:

^ 2+2 = 4, but 2 cores per CPU * 2 = 2 dual core CPU's.

Reply to Helloworld_98

It still has four cores though.

Really!?

He's trying to answer his question stfu.

They are not known as 'true quad cores' because of the marketing thing AMD did with their quad cores when they came out. Intel made quads by sticking 2 dual cores together where as AMD made them from the ground up. (and now intel is with the i7s, for obvious reasons of the i7 not having any duals or starting with any duals whatsoever)

Exactly, so perhaps you should stfu and and go look up the definitions of 'true' and 'quad'.

It's still a quad core. And the Core2Quads perform on the same level as any Phenom2s. The Core2Quad Q9550 that goes for $170 at Microcenter beats a Phenom2 Quad that goes for $200 at Microcenter.

He was not saying he didn't think they were 'real (true) quads'. He was more so quoting the OP and what AMD (and pretty much everyone pro-AMD) was saying, and you were giving HIM *** and being a smart ass for it...? Everyone has been calling the AMDs 'true quads' because of that, he was trying to speak and answer the best way for the OP to understand.

You're like one of those people who thinks the way he pronounces coupon is the correct and only way. Soooo perhaps we should BOTH stfu and YOU should learn how communication works a little better.

Anyways, intel is being extremely competitive. According to newegg intel looks like the best bang for buck (in quad cores) if you are overclocking. Reason Phenom gets so much praise is the higher stock clocks. It's sad but very true. Though it seems the P2-955 is $30 cheaper than the 9550. This looks about even, some may disagree with me but I think (in my mind I KNOW) the 9550 beats the 955 up and down, and is worth more than $30 extra. The new I5s could make P2 obsolete if they do it right, we'll have to see.

hahaha !

A friend of mine have a 955 rig with a HD4890.

3.8ghz vs 3.8ghz im 2k over in 3dmark06 with my GTX285 and Q9550. + He have 4g DDR3 running @ 1333 and me DDR2 @ 900mhz. I can tell that for gaming, my rig overpass his rig. But not that much. Just a lil notch.

two things

What is IPC? inter process communication? and what does it do?

is the C2Q quad or not?

C2Qhas two sets C2Ds so two teams of two that have to talk to each other versus the i7 which has a team of four people that talk directly together so that makes it a real quad core. and faster.......

right?

C2Q is a quad core, and it is real. The fact that it has 2 dual cores in it makes no difference in performance. People have been calling the i7 real quad cores because they were built from the ground up without putting 2 dual cores together, but it really makes no difference. The i7 is only faster because it is a totally different and newer/better architecture.

^ isaw that but didin't really help on how it is used or how it ismeasured like how can you tell that new i7s have (faster or better?) IPC than old ones?

Reply to Upendra09

GOOGLE is your best friend.

Find a 1m calculation ( SuperPI ) from :

Pentium D 3.0ghz
E6850 3.0ghz
E8400 3.0ghz
OCed I7 @ 3.0ghz

and youll see that the SAME 1m calculation is faster and faster and faster ... they are all 3.0ghz proco ... WHYY !!!! WHY THE **** ... cause they are faster and faster clock for clock. I7 have more bandwith cause they have the mem controller directly on the die and this helps alot.

+ newer architecture, bleh bleh. its the way things are, generally newer things are better. GENERALLY !

IPC = Instructions per cycle. Clock speed and number of cores alone doesn't give you the whole performance picture because some microarchitectures are more efficient than others and can execute more program instructions in a given number of clock cycles. More detail in this Wikipedia article.
