Many seem forget to calculate the real world latency, since DDR4 often works faster even with higher rated latency in cycles the real world latency is lower.This makes me feel better about my choice of upgrading from DDR3 1866 to DDR4 3000 on my Sky Lake build. Those higher latencies did put me off a bit.
Reason to use DDR4 over DDR3: voltage. If you are chasing speed with 1.65v DDR3 in an attempt to keep up with DDR4, you're out of spec on Skylake. If you fry your mem controller, that's because you thought you were smarter and could "cheat" the system. Yes, you may get a configuration that is temporarily faster for today, but will it still work properly in 6mo? A year? Is shaving a few seconds off a long encode or a couple FPS out of 100 really important enough you're willing to deal with instabilities and repairs down the road?We know DDR4 is better, its just not worth upgrading simply for DDR4. Upgrade for other reasons, such as features that Skylake has.
People are still satisfied by sandy bridge, but upgrading now will bring a lot to the table. M.2, DDR4, more native usb 3.1, faster CPUs, lower power usage, etc. Upgrading for one reason is silly. Upgrade for the platform.
i3.lmfao i3 doesn't support ddr beyond 1600 and it's fsb is limited to 1333 in all i-3's pointless to even bother with i-3 it's work station cpu.If you really want to compare the memory performance in games, you have to pick games where the CPU is easily a bottleneck. GTA V for example. Not BF4... And, using a weak CPU instead also helps. So, an i3 rather than an i7.
idk where the cas11 came from 8-8-8-24 was the standard for ddr3 1600 aside from 9-9-9-24 which was considered the slow stuff CAS wise. this cas 11 stuff only came out when you were trying to buy 1600 for $20 for 8gb sticks, seemed like a purposely built handicapped ram just to make ddr4 look attractive, much like the 64bit ddr5 video cards vs the same model 128bit with ddr3. 128bit ddr5 models refute everything said about 64bit even if it had ddr12 soon as you bumb up that bit width back to 512 like the ati3850 and 3870's they destroyed anything 256bit or less."Consider that CAS 11 is the most-common latency standard for DDR3-1600"
Simply not true, the most common latency for DDR3 1600 is CAS 9, I don't think I've ever even seen a 1600MHz stick with a CAS latency of 11 (other than cheap value RAM), CAS 10 is more common than CAS 11 even, but really it should be CAS 9. In fact CAS 9 can and has been used on DDR3 modules up to 2400MHz, further making your use of CAS 11 on 1600MHz bunk...
ya it's a repeat of ddr1 vs ddr2 at the 400mhz level and ddr2 vs ddr3 at the 1066 levelWe saw this same thing when DDR3 came out. "Is Core 2 better with DDR3?" We saw DDR3 come out at 1066, when DDR2 was just reaching 1066 and even 1200. And no, DDR3 wasn't any faster. As a matter of fact, it was slightly slower. However, DDR3 was able to stretch on and get faster than DDR2 would ever have been able to do.
It doesn't really matter. DDR4 is needed for the future. We need a point where people start adopting it. That point is now. The platform is this one.
So, stop griping about it.
