6th Gen with ddr3

[Sahadath]

In my country core i5 4690K and core i5 6600 are same so should i go for 4690K or 6600?
I am not want to OC. Another thing is can anyone ensure me that 6th in good with DDR3 or i have to switch 100% to DDR4?

At this point in time, the decision between Haswell (4th generation) and Skylake (6th generation) usually comes down to the differences between cost in RAM (DDR3 vs DDR4) and motherboards.

Skylake requires DDR4, Haswell needs DDR3.


Skylake is a little faster, but not significantly so and is of course the most current generation.

Most of Skylake's gains come from running fast memory (DDR4).

You CAN run DD3L (low-voltage DDR3), but there's not much point, as it's just as fast as Haswell at those memory speeds. Regular DDR3 should be avoided with Skylake builds. Yes, some motherboards *may* "support" it, but the voltages are higher than the internal memory controllers and will shorten the life of the processors.

There is very little difference in speed between DDR3 and DDR4. Please don't spread misinformation.

There is, at the higher DDR4 speeds, and paired with Skylake memory controllers. Very slim margins, but still an improvement nonetheless. 2133 is a bad test case when there are higher memory speeds now on the market.

Please, provide links to relevant benchmarks. Don't just say it, prove it.

DDR3L-1600 (a more typical DDR3 speed) vs DDR4-2133

Very small improvements between 2133 and 2666, but improvement nonetheless.

Like I said, very small improvements, barely noticeable to the average user, but nonetheless, they are there. At the same time, not drastically faster than Haswell with DDR3 either, though, but the gap widens very slightly with faster DDR4 memory.

OK wow. Look at your first post when you said.

Now you totally back off that. by saying:

very small improvements, barely noticeable to the average user,

I'm not seeing how those two statements are contradicting each other. Both are true.

Personally, I don't think I'd go for the Skylake over a Haswell build, because indeed, there is very little performance advantage between the two. However, if I already HAD the Skylake build, its main advantage is coming from the new technology - DDR4 + support for fast PCI 3 SSDs. The increased transfer speeds between PCIE lanes and DDR4 are this generation's main performance advantage, and maybe next year's processors will take better advantage of what the chipset has to offer.
