i5 2550k no on die gpu?

[darknite]

Spotted the new 2550k does not have on die gpu. So does this mean you can clock the bclk?

What is the gain of not having the on die gpu?

No on die GPU means a cheaper chip for intel to produce, hence a better profit margin. Most users of k series chips have a separate graphics card so it won't affect them. The only thing you lose is quick sync. Still no base clock overclocking though.

Shame. I thought the restriction with bclk clocking on these cpu's was the on die gpu.

Thanks for the prompt reply!

Do you recon they might run slightly cooler without the graphics chip in them? maybe need less voltage for OCing?

Would like to see some OcUKing results (*Cough* Gibbo)!!

Aye, with the LGA1155 platform the BCLK is unified - so it is used to also drive other important signals, hence why it can only be varied very slightly while maintaining system stability - disabling the graphics core doesn't affect this.

Pretty much the only gain of the 2550K chip is the slightly higher base clockspeed (3.4GHz vs 3.3GHz). The real benefit is to intel who can now sell the quad core chips with defective graphics cores (but otherwise fully functional CPU) which have been piling up since the launch of sandy bridge.

It is unlikely that they will run any cooler or overclock any better as on the i5 2500K the graphics core is disabled anyway if you install a discrete graphics card.

so more of a disabled iGPU than a non existant one.

This, binned parts

Yea, this isn't a new design chip with no graphics core installed (like the SB-E chips which have no graphics core at all), instead this is just a standard sandy bridge LGA1155 quad core like all the other i5 and i7 2000 series, but with the graphics core disabled in the factory.

This makes sense, that way they can sell all of the perfect CPU's that simply have duff GPU's.

Why the chip is £20 more though for a mere 100mhz when a very useful feature (iGPU) is missing I have no idea, it should be priced the same as 2500K or slightly less tbh.

Intel can charge what they want at the moment though. Where's the AMD competition for this chip?

Well no doubt it's better than anything AMD offers but I can't see many people buying it over a 2500K.

In their i3 range you have:

i3 2125 3.3ghz/HD3000 - £112
i3 2130 3.4ghz/HD2000 - £113

That is much more sensible pricing because it's a simple choice between an extra 100mhz or a better iGPU, whereas with the i5 they're charging £20 more for no iGPU at all... not even a HD2000. Worst still is the fact that they're both K models and can be overclocked so why even pay for the extra 100mhz?

It would have to be the dogs dangly bits when overclocking (compared to normal 2500K's) to justify the price.

 

[Blue160]

If you're right the pricing will come down because it won't sell.

 

[darknite]

You're right, it might not sell so prices may fall. Depends if people can wait until mid april for new cpus. . . .

 

[Kelt]

So for anyone who can overclock, an absolutely pointless CPU, and more expensive than an I5 2500K!

 

[Uther]

Pretty much yes IMO.

 

[the1gooner]

On special today so will be good to hear from anyone that buys one as to it's overclock potential.

 

[mmj_uk]

£174 is far more sensible pricing but I still don't think many will buy it over a 2500K unless they're under the false impression it's a 2500K+100mhz.

In terms of overclocking I'd expect it to be a lottery, sure there will be 2700K quality chips which had faulty iGPU but at the same time there'll be those at the lower end of the spectrum.
