Lastly, If you really use applications that need memory bandwidth, you should not be using 115x CPUs at all. That's what X58/X79/X99 are for.

I was commenting on those games. For example 2400Mhz gives noticeably higher min. fps in them, just like noted in couple of threads here.

On Skylake, even games can benefit from faster memory, there is a difference between 2033 and 2600 on Skylake, past that it can be a bit neglible but there is no reason to buy slower than 2600MHz memory on Skylake, even faster than that is not much more expensive.

Older gens did not benefit much if any at all from faster memory, that is true.

The amount of bump you get depends on how much of an increase in memory speed you're making... if it's only a few hundred mhz, no big deal on any system...

The thing with older gens is that the IMC can only be OCed so far. DDR4 is relatively new and with higher timings than DDR3, so they compensate with higher clocks on Skylake, plus Intel already knew how to build a beastly IMC as they had already made Haswell-E. However anything Sandy can only get to 2133 MHz so far in average, but CAS 9 timings which makes it go on par with DDR4 which is faster but with looser timings..

True. But DDR3 can not be compared to DDR4. Even at slower speeds and loose timings the DDR4 will out performance DDR3, granted some of that is because of newer cpu as well but fact is DDR4 in the end is faster than DDR3 even at terrible timings and relatively slow clock speed ie 2133 @ 15-15-15.

Here's a test of a 4790K against a 5820K that doesn't show a bit of difference between the two, even with DDR4 running at 3000 vs. DDR3-2133: https://www.youtube.com/watch?v=utWnjA4NzSA

Newer memory technologies always take a while to prove their worth. Certainly, if someone is upgrading their whole system, they should probably choose a DDR4-based platform, but fast DDR3 is still competitive today and should be for some time to come. Getting DDR4 is no reason to retire a 2500K-based system if it's still doing the job. In fact, if you can hold off for a while longer, you might be able to get faster DDR4 that actually will provide a performance benefit.

Outside of your claimed 10fps difference (I am surprised its that high actually), If you look at CPU benchmarks, to benchmark A CPU... you will find it is a different story:

https://www.cpubenchmark.net/compare.php?cmp[]=804&cmp[]=2565
http://www.anandtech.com/show/9483/intel-skylake-review-6700k-6600k-ddr4-ddr3-ipc-6th-generation/13

If you would like to improve your gaming experience I would be looking else where. Overclocking your graphics card might claw back some of that 10fps difference.

If your typical workload is often CPU limited.. well there you go.


The answer to this i assumed to be obvious, i play games and dont run synthetic benchmarks on a daily basis?

http://www.overclock.net/t/1578480/i5-2500k-4-5ghz-vs-6700k-4-5ghz-in-games

Its not that i dont trust this guy, i just dont trust the internet lol. Upwards of 30 average fps gain between the 2 CPU's, ya i have a real hard time swallowing that. Even in MMO's you wouldnt see anything near that high of a gain, and from my experience they are the most CPU intensive games out there.

Just to be clear, say linus put up a video showing i could gain even 20 FPS in WoW or another MMO i would drive up to microcenter that same day. I want to do a new build, but i just cant justify the gains vs cost.

I can afford a nice $1000+ 5960x, fancy new high end motherboard, new extra awesome DDR4 if I want. It's not going to do much more for me than the system I have now for what I use it for. My 980GTX is more of an issue than my 2600k, IMO.

Might as well just order a 6700k and an Asus or MSI X99 board and some uber DDR4 memory and see how much more fun it would be than what you have. I guarantee it won't be $500 more exciting. Oh, and Skylake bug. lol

That test makes me giggle. Its like showing me that a drag car with bicycle tires is no faster than a street car in a drag race lol.
