SB unfair in comparison reviews

[perdomot]

All of the reviews I've seen so far that include an i5- 750 seem to forget that the 2500K is over 600mhz faster at stock speed. I'd like someone to OC the 750 to 3.3Ghz and see how much advantage the SB really has. Has anyone seen a review like this yet?

 

[RyanGreener]

Haven't looked into SB much lately, but from what I remember, SB is more power efficient + OCs more, which might be it's advantage?

 

[gevorg]

Doing this will make SB look pretty bad since there would be barely any difference.

 

[richierich1212]

perdomot, you've figured out 99.9% of the reviews

Keep telling yourself that

I don't think any of the reviewers forgot that SB cpus have faster stock clocks than older cpus. I think YOU forgot that is how reviews are done, comparing what you can buy to another product (in the form that you buy it in, not overclocked).


When you buy a 2500K, you REALLY are getting that much more. Intel guarantees it will run at that speed.

This is a pretty silly objection to the reviews. If the two chips cost the same amount of money and one has a better architecture and design and can outclock it and out perform it and are aimed at the same market segment, how is it a bad idea to directly compare them?

 

[StinkyPinky]

It is comparing two retail products you buy at a store. You don't buy the 750 overclocked so why give it an artificial boost?

Um dosent the AT review clock them the same? 3.3ghz i think they overclock the old i7's to and it shows that sandy bridge barely outpaces them at all.

Well because its interesting to see if there have been any improvements in IPC or if this is basically just a die shrink with onboard graphics. As it stands its a die shrink with onboard graphics, there isnt much improvement in IPC at all.

Does this really matter when the $220 2500K bests the $294 i7-950?

 

[Phynaz]

What would the point be?

If you are going to time a Vette against a Malibu do you take 4 spark plugs out of the Vette?

 

[richierich1212]

No, you overclock both to the same clocks

So what? It still retails at a faster clock speed. That's like asking to downclock the 2500k to the 750 speeds so it is "fair". How is that "fair" to the 2500k?

At the end of the day the 2500k is guaranteed to work at its spec speed, as is the 750. Any overclocking is up to the user. To artificially boost one but not the other would be unfair.

Cars != CPU

Why not tie a rabbits back legs together so it only has two then race it against a human. Dosent work, makes no sense, bad comparison, no

Clock for Clock comparison, SB vs Nehalem

 

[Markfw]

Actually, I think there are two frames of mind her, and both are valid.

IF you are an overclocker, you want to see what both chips can REASONABLY do on a consistant basis, then bench them at those speeds, comparing chips of like price (including platform).

If you DON'T overclock, then take chips of like price(including platform) and compare them.

At least those are the 2 views that I see, but both are perfectly valid.

 

[AtenRa]

Actually Core i5 750/60 are being replaced by Core i5 2300 at $177 and not by Core i5 2500K.

This is exactly what I was thinking. It would be an interesting comparison, to see them both clocked the same, but I wouldn't call it unfair.

I feel like the only one in the room who cares more about the lower power consumption and that I won't need to buy a cooler that looks like something out of a Dr. Seuss book.

Why do there have to be winners and losers here?

People like to argue. It would get bored in here if we all agreed

I think Sandy Bridge will be more of a home run for laptops.

but then you should bench the Sandy Bridge cpu at a speed of 4400MHz at least. The OP wants the SB benched stock vs. an overclocked cpu. I can see the point of wanting that info, just for forum talk 'n all, but how does it help in real life? If one is OK overclocking older cpus, they are likely OK with overclocking the new cpu.

 

[Edrick]

Comparing a overclocked CPU vs a stock CPU is not fair. And serves no purpose really other than maybe comparing IPC clock for clock.

I have seen one of these reviews where they compared a 2500k to a i5 750 at 3.3Ghz. I will try to find the link.

Ah, okay. Carry on, then
