whats the difference in k series haswell orn the other one

Solution


The i7-4xx0 (non K, S, T, R) are the baseline models. They have all hardware features activated. The clock multiplier is locked.

The i7-4xx0K series are the enthusiast models. They often have business and enterprise features such as VT-d, Vpro, and the brand new TSX-NI disabled. They are meant for gamers and overclockers.

The i7-4xx0S series are low power models. They have a slightly lower clock rate, but much lower TDP. Feature wise, they are the same as the baseline models.

The i7-4xx0T series are ultra-low power models. Same deal as the S series

The i7-4xx0R series (unreleased) will...
Look a typical 4770 would be same clocked as the 4770k

But the difference between the two is that the k version is easily overclockable and factory unlocked with a multiplier so pretty easy to overclock


There is no diff in 4770 n 4770k except overclockablity for more info check the link

Now 4770s is a cheap downgraded version of 4770 which is downclocked

The i7-4xx0R series (unreleased) will contain a more powerful IGP. Although it is presently unreleased, Intel's specification shows it as having the same features as the K series processors, with VT-d, Vpro, and TSX-NI disabled. I am unsure if the clock multiplier will be locked.

Haswell chips are supposedly a bit more difficult to overclock than Sandybridge or Ivybridge, but most review sites have used Asus RoG boards to take Haswell chips up to ~4.7Ghz
