How many cores are in the new Intel's Core i7 processors?

Lynnefield has 4 physical cores (i7-860, i7-870, i7-875, and some i5-7xx)

Bloomfield has 4 physical cores (i7-930, i7-940, i7-950, i7- 960, i7-975EE).

Gulftown has 6 physical cores (i7-980x, i7-970)

All i7s have hyper-threading, so 1 physical core works as 2 logical cores.

However, multi-threading is not perfect, so a hyper-threaded core can only do the work of about 1.2 physical cores.

NO OFFENSE, yet you have very constrained pc awareness, and that's purely being polite... an uncomplicated answer would be: 4 is larger than 2... those are 2 thoroughly diverse processor fashions and technologies. The lots extra moderen technologies Intel middle i7 is a quad middle processor (4 actual processing cores), lots speedier and extra effective than the previous twin middle Intel middle 2 Duo (in uncomplicated terms 2 actual processing cores). Intel middle 2 Duo is previous, released back in 2007-2008. What you are attempting to ask is that if a center i7 will play a activity that has a minimum or cautioned requirement for an Intel middle 2 Duo. the respond is definite, and you gets lots extra effective gaming overall performance from an Intel middle i7.

4 cores and 8 threads.

it supports hyper threading technology.

it is best suited for gaming.

it has 6 mb cache memory.

That would be the Gulftown, and it has six cores.
