DDR4 will not be any where near 3000mhz on launch. No way!!!
I've tried my best to explain this as the thread has progressed. Now I could be wrong, but, from memory....
When DDR3 launched it was terrible. First off, it was terribly incompatible and there weren't many vendors pushing it out. OCZ was one, it was awful. In fact, I still have two 'launch' sticks of DDR3 and they are 1.85v and the timings were laughable. As we know, DDR3 had terrible timings and it's only been very recently that they have finally been able to match the timings DDR2 was on when it was supposedly phased out.
And the same happened when DDR2 launched. DDR was hitting speeds of close to 500mhz, DDR2 launched at 533 only the timings were far slacker. History repeated itself.
As I said before, I could be eating my hat here but I strongly doubt it. If history repeats itself as it often does in the world of computing then DDR4 will be -
No better than DDR3 at launch, and will take at least a couple of years to settle in.
Be prohibitively expensive.
But then I guess if you can see Haswell E for what it is (Haswell, only with more cores and DDR4) then like any other technology you'd be well advised to avoid it at the beginning. Prices will be high, issues will be common.
What I want to know (and tbh? it's the only thing I can't really figure out myself using 30 years of knowledge) is how it overclocks. It needs to if it's going to be £1500 or so for the top end CPU board and ram.
If it's more of the same Haswell? then maybe people will finally learn. Honestly, if it has trouble overclocking due to heat and so on then it's not going to catch on.
With CPUs I have always stayed a couple of steps back. I'm glad I did too, because I don't like buying bad products.
Boom.
** mod edit - less of the personal insults ** . I asked for benchmarks from a I5 2500, not a 4790k. If you wanted to wave your willy go do it against people with rigs that aren't as good as yours. My SBE chip hits nearly 1300 points in R15, miles beyond your paltry 4790k.
If, of course, it was a willy wave on your behalf (come on now let's be real, it totally was).
I've also got SLI Titans if you want me to start posting irrelevant spam?
To those who can read between the lines.
Thank you. It's nice to have some reasoned, well thought out intelligent discussion with you.
