Intel To Launch Sandy Bridge LGA1155 Processors That Lack iGPU

"Visibly Smart" was the tagline with which Intel brought its 2nd Generation Core processor family codenamed "Sandy Bridge" into the market. What every Sandy Bridge chip in the LGA1155 package launched thus far has in common is its integrated graphics controller. Apparently, Intel is planning to launch three new Core i5 quad-core processors, which lack that integrated graphics. The processors very much will work on H61, H67, and Z68 chipset-based motherboards, only you can't use the integrated graphics, making them functionally-identical to first-generation LGA1156 Core i5 quad-core chips.

The Core i5-2550K, which has been talked about for the past few weeks, is one of these three models that will lack iGPU. This chip is geared for overclocking, as it features an unlocked base clock multiplier. The other two models are the Core i5-2450P, and Core i5-2380P. Intel is perhaps counting on the "P" marker to intuitively denote lack of iGPU, like with P67 chipset. Clocked at 3.10 GHz with a Turbo Boost speed of 3.40 GHz, the Core i5-2380P is clocked identically to the Core i5-2400, except of course it lacks the iGPU. The Core i5-2450P, on the other hand is a little unique, with a clock speed of 3.20 GHz and 3.50 GHz Turbo Boost speed. Pricing and availability are not known, though it is expected that some of these chips will be priced lower than existing models with iGPU.

Does this matter for overclocking?

When you don't use the iGPU, does it still consume power/create heat?

Wonder how this will affect overclocking and power usage as well. Most of us who have 2500k/2600k/2700k arnt using the IGP feature and those of us who have a p67 board don't even have the option too.

Is this a new die?

I wonder what exactly does this entail. Is the chip physically any different to the i5-2500k, or is it just deactivated? Also, what are the results of that on heat/power consumption?

The weird thing to me also is that the naming would suggest some sort of performance gain, or at least an improvement of some sort (if not in raw performance, in overclockability).

Also weird is the timing of this. Considering this isn't on the market yet, it's basically got four months to sell, then it will be superseded by Ivy. If the only gain the 2550k has over the 2500k is lower head and power consumption, odds are that Ivy would bring an even bigger improvement.

Intel won't make a new die for a handful new models, and when Ivy Bridge is three months away. It's most likely the existing die with iGPU gated.

that's right btarunr
intel expert in cutting the cpu in pierces and sold in different name... and keep changing the socket as well.. lol

Such a cpu with a new die would be really great for low-power gamer builds (where there is a dedicated graphics card), but not sure about these, the same die won't overclock significantly better like this....

well, perhaps if it's much cheaper....

Oh well, then the decrease in price is justified. Although users will miss out on the Quick Sync feature entirely I guess.

why do ppl say that sb is 2nd gen core family?
when really its 3rd
first core was 1366, the came 1156, and THEN came 1155, i see that as third

It's 2nd generation from Intel's logic of "Tick - Tock" Where Sandy Bridge is Tick, and Sandy Bridge-E is now the Tock. Ivy Bridge will be the new Tick making it third generation I believe. The tock of every generation has always just been the refinement of the tick.

I thought certain models already existed without the iGPU. Guess not.

1156 and 1366 are first-gen (Nehalem), 1155 Sandy Bridge and 2011 Sandy Bridge-E are second-gen.

Besides, it's not just "ppl" that call Sandy Bridge "2nd Gen Core Family", Intel does it as well.

In other words, they're chips that have good CPUs but defective GPUs. They must have good yields if it took them this long to build up an inventory of them.

Xeon's yes, Core i consumer models, no.

Better be more than a few $ price cut for this. If they charged more for removing their eyesore of a GPU, I think I'd be rather irritated.

Or they have binned enough faulty ones.

Good. They should have made them from the start. I was going (still am...eventually) to get a P67 board anyway, so I had no intention to use the iGPU.
I should be getting the one that has the same performance as the i5 2400, since it has moved up the price scale, thanks to the introduction of the 2320... :

No. SB and SB-E are the same stage. I can't remember which is tick and which is tock, but it goes:

-New tech (Conroe, 65nm)
-Die shrink (Penryn, 45nm)
-New tech (Nehalem, 45nm)
-Die shrink (Westmere, 32nm)
-New tech (Sandy Bridge, 32nm)
-Die shrink (Ivy Bridge, 22nm)

Notice how each new architecture ("tock", iirc) brings a new socket or pair of sockets, which the die shrink is compatible with.

As I understand it, Nehalem and Westmere are considered the first generation core architecture.

My guess is to get rid of their stock of dies with bad GPUs.

You're right, I simply had it explained incorrectly in the past by a moron.

It will be interesting to see how removing the IGP impacts performance, overclocking, and price.

Just got me a 2500K, and I'm very happy with it so far. But I always contended that I don't need the GPU in it, so it would have been nice if these have out a little earlier.

No big deal though as I got a good deal and who knows, I may use it someday.

I'd never buy this cpu if your comment is true.
