[VrZone China]Haswell Support DDR4 memory, Haswell-E fastest debut by the end of 2014 - Page 5

post #41 of 127
I heard that AMD was going GDDR5 for system RAM. There was an article about it around here, maybe a rumour. Is DDR4 faster than GDDR5?

On first release, DDR4 is only going to be slightly faster than most DDR3 versions.

By the time DDR4 outspeeds GDDR5, that's when GDDR6 shows up.

Usually get a new architecture, followed by a revision (Tweaking of the existing arch Then a new arch and cycle continues.

I have faith that AMD are gonna pull back some ground in the high end CPU space next year. Maybe not enough to beat the 3960x but whatever comes after will be decent enough to warrant an upgrade. Broadwell E may be the one to wait for though.

No, and I suspect that rumour is crap...GDDR5 has a lot of bandwidth but high latency, it'd be good for the IGP but the CPU may suffer.

True, as Piledriver is a bit of a Bulldozer 2.0 while SR is much bigger.

On desktop apps? Of course not. BD/PD is a very good server arch but a terrible terrible desktop arch
SB-E on the other hand vice versa. AMD does very good on the server market for multi-proc systems but Intel does badly because the only ones they have are expensive to hell
and not to forget if it performed underwhelmingly why are so many server OEMs selling AMD now? Unless you didn't know that now you need to. My dad manages servers and every new server locations built seems to have AMD not because of cost but because PD on Server environment performance is VERY GOOD.
Who cares about single-thread performance here? NOBODY DOES. It's all about the amount of scalable performance across threads. That intel can't do much more than 10% with HT

and both DDR3 & DDR4 have far less latency than GDDR5.

I'm curious if the timeline in that article is to believed. Here is what I think they are saying:

- Haswell in June 2013 (we know that)
- Ivy Bridge-E at the end of 2013, 22nm
- Broadwell sometime in 2014, 14nm
- Haswell-E at the end of 2014, ddr4
- Skylake in the first quarter of 2015, ddr4


It seems unlikely that Skylake could be ready in a year and half from now. It also looks like the -E's keep getting pushed further back such that they are almost always either a process node or an architecture generation behind.
