So either I missed something somewhere or most likely just dont comprehend it. But with the new intel core i5 or some i7's with the integrated graphics on the same die, how many cores are there actually? since one core is the graphics..

So does this mean a quad core is actually 3 core cpu 1 core gpu.. or is it still 4 core cpu, 1 gpu making it a 5 core?
thnx

More about : cores core

None of the currently available Intel CPUs have graphics on die. That is planned, but currently unavailable. From what I can tell, i5 CPUs are those which have 4 threads. This means they are either 4 cores without SMT (1 thread per core) or dual cores with SMT (2 threads per core). Currently, the i5-750 is the only i5 available, and it is a quad core without SMT.

What he said. The i5-7xx processors are four cores, four threads. From what I gather from branding rumors, i5-6xx will be two cores, four threads + graphics.

I also think there will be a i5 with 4 CPU cores and 8 threads. Or will they retain that for Cire i7 LGA1366.

Core i7 on 1156 also has 4 cores and HT (8-threads). The Havendale I believe will have the GPU on die. 1155 chipset?

Core i7 / Core i5 = Four CPU cores only:

from this article

Future un-named CPU in the Westmere family will have the CPU and GPU in the CPU package:

I think the naming system is based on number of threads. i3 = 2 threads, i5 = 4 threads (whether via a dual with SMT or a quad without), i7=8 threads, and possibly i9=12 threads.

After that you'll have SandyBridge which will have the GPU on the same silicon as the CPUs:

SO then Core i13 would mean 16 threads? Or Core i14..... Man this will hurt my head....

Interesting. So I think its going to have the GPU connected to the L3 as well/. Wounder what that will do for it.

Who knows. Maybe they'll abandon that naming system before that would happen...

That wouldn't work, I3 is a dual core with HT to enable 4 threads.

That would mean no distinction between i5 and i7.

Rumor has it the next series will be called "Cores-a-Plenty" :D

AMD has their "Magny-Cours Multiprocessor" or MCM as I like to call it.

I'm pretty sure that i3 is a dual without SM, with only 2 threads, and that duals with SMT enabled would be branded as i5.

i3, i5 and i7 are replacing Celeron, Pentium and C2D/C2Q. Basically i3 are entry level CPUs, i5 are mainstream parts and i7 performance/enthusiast. It's more about 'branding' than how many cores or threads.

The Pentium brand stays, below i3.

Surprised they don't call it an aye-aye, as in "Aye-aye, 3 bags full Sir!" :D .

OTOH, AMD already beat Intel to the last level - they have the 'eye-finity' :) .

For our dear friend jennyh, I'd suggest a specially branded CPU - the X-eye-X (a Crossfired i-core, or cross-eye for short :D )

Well for the Core I(x) it would be odd numbers. i5 i7 i9 i11 i13 ect.

cores/ht

i5: 4/4
i7: 4/8
i9: 6/12
(if they continue this trend then it should go like this)
i11:8/16
i13 10/20
Ect.

cant say it hurts may head.

Yeh, and if you get a dual socket mobo and stick an i7 and an i11 in a Hordirc Cube, you get a puppy

It would be i5, i7, i9, iB, and iD if we were consistent with our inner computer nerd.
