So i was reading about skylake cpus and am wondering.

When are they coming( 2015?)

Should i wait for them for building my pc.

Any other relevant info( only using ddr4)

Cost

Cost for ddr4

Thanks for all answers

http://en.wikipedia.org/wiki/Skylake_%28microarchitectu...

it looks like they will still be supporting ddr3.

i think ddr4 will mostly benefit discrete graphics.

no k models to start... must really be powerful.

i was told that will be 14nm or 16nm gpu's to match.

a friend of mine has a 6 core haswell with 32gb of 2400mhz ram that he uses the discrete graphics and i am pretty sure that it can max settings in anything you throw at it and some games even at 120fps.

I think laate 2015 or q1 of 2016 , maybe a new socket , and the first motherboards will come with 2x ddr3 and 2x ddr4 , as we saw in the past 2x ddr2 + 2xddr3 .... .
It will most likely have a noticeable performance increase from the previus generations ... maybe as much as 20% with same amount of cores and same clockspeeds . they will most likely add native 8 cores + hyperthread meaning 16 logical cores on the top tier desktop cpus , also increase clockspeeds a bit , and with power draw under 90W. Also maybe more pcie lanes like +16 ...
BUT the big problem will most likely be the price ....if AMD can't make something spectacular(i mean ultra high end that can compete with a skylake based something like > i7-4960x) .... , cause right now intel dominates server cpus , and high end desktop cpus , also most laptops and almost every ultrabook .

This may be offtopic but i'm more interested in under the nanometer scale cpus,gpus,memory modules , like having the power of a GTX780ti+i7-4770k+16Gb ram+1Tb storage in your pocket for under 1000$ ......that may be 20 years away but....

Quantum computing is some amazing stuff but the programming algorithms need to catch up with the hardware as we see today in silicone.

I think 14nm will be the end of the road for silicone in say like 4yrs.. and graphene will begin to steal the show.
Of course at that point the skylake will remain a good solid machine for some time.

yeah cpus never really outdate to much i mean dont use a Pentium that struggled to beat an athlon at half speed its gpus that outdate especially if its 64 bit bus on agp your computer sucks then. And on graphene you can go to 1000ghz but the problem is it doesnt turn off.

well not too long ago we had 1-2-4 threaded cpu's in servers , well 16 may sound much but as we converted from single core to dual core (mainstream of today) , getting more and more quad core , even in laptops (with 8 threads) , than it's pretty much possible that 16thread will happen .
Even nowadays we have http://ark.intel.com/products/75279/Intel-Xeon-Processo... cpu's. Well it's more than 2000$ , and not very suitable for gaming , but in 10-12 years 16 threads will be the mainstream of good gaming PC's , and of course workstations.

5th Generation Intel Core CPUs will stay on LGA1150. Most Z97 motherboards say 4th Generation and 5th Generation Intel Core processor support. I know mine does and the ASUS boards that I was looking at do. For DDR4, we will have to wait and see, but according to many sources, the price will in the beginning (Q3 2014) will be very high, maybe twice DDR3. That is when Haswell-E CPUs like the Core i7-5820K (6C/12T, 3.3 GHz), Core i7-5930K (6C/12T, 3.5 GHz), and Core i7-5960X (8C/16T, 3 GHz) are released. By Q1 2015 when Skylake CPUs come out, the price will drop to DDR3, maybe even lower than DDR3. DDR4 has about 50% more memory bandwidth and 35% better power consumption. As of now, it is not really going to be worth it due to the 100% more price. I just had a large decision about this same thing (and also whether or not to wait for Devil's Canyon) and just went ahead and got the Core i7-4770K. If you can wait longer, you should, but if you want performance sooner, go ahead and buy the current Haswell CPUs (Devils Canyon). The Intel CPUs have followed a trend of only offering about 5-15% more performance of the last generation. Plus, Haswell CPUs are having large price drops now. My advice is to get Haswell if you can't wait, but if you can and have money to possibly buy a Z97 Refresh (DDR4 Support) board that will probably cost more due to DDR4 hype, but will eventually go back down, go ahead and wait.

From a Core 2 Duo to Haswell would be an insane upgrade, and with the 4790K, probably about 6x the performance. For a gaming or rendering PC, a server PC would not be good. A Xeon would not help in gaming and would hold you back because of the lower Single-Threaded performance and having SO many cores. To summarize, a Haswell CPU would be a huge upgrade, depending on what CPU you would get. Even the new Devil's Lake Pentium will be a lot better, about double the performance of a Core 2 Duo. The Pentium has a higher Single-Threaded performance than an overclocked 3770K! It is about equal to a quad core AMD CPU and my Core i5-3210M (2T/4C) and doesn't offer hyperthreading, so that's right, (2C/2T), and maybe better. The new Pentium would be a great choice if you can't afford the Haswell i3-4330, which would be a great choice. To hit the sweet spot with Haswell, a Core i5-4690K or Core i7-4770K would suit your needs quite well.

Alrighty. If you are gaming, get the 4690K. If you want to be sure of no bottleneck and want to render and record, get the 4790K. If you wait, then you may have a while to wait. For another thought on the GPU, right now, the MSI Radeon R9 280 is $229, so you could grab two of those and Crossfire for $460 and have better performance than the 780 Ti and the R9 290x, with a little more power consumption. My 270x's already beat 780 Ti's in Battlefield 4, 3DMark, and pretty much everything else. 280s have 1.5 times as much power, so you could be WAY about 290x and 780 Ti performance, and if you overclock, I can't begin to imagine the performance.

You should go with the 4790K, not the 4670K. It fixed many of the heat issues with Haswell and will all around perform better than a 4670K. And about the Crossfired 270x's, they are awesome. Because of the recent price drop of the 280, Crossfire those and you should be set for EVERYTHING.

you got a little double post on your chin.lol. but i think a 4790k is to expensive. I might consider your pentilum offer, get a r9 290 or crossfire 2 gtx 760 or r9 270x and upgrade to skylake and ddr4 when they come. Is the pentilium 4 75mhz single core good XD.

lol. You should just get a 4690K. Crossfire the 280. One 280 is better and cheaper than a 760. 2 are amazing.

R9 295X2 is better than crossfired 280s (2 290x's in crossfire and slightly overclocked), but it is also 3x as expensive... That aside, free games don't mean better performance. Crossfire is great. For about 4/7 of the price of a 780 Ti, I get better performance. There are games that are poorly optimized like Watch Dogs (which should get better with time) that do have stuttering with Crossfire, but other than that, it is awesome. As for DDR4, it is really not necessary yet, but I do see reasoning for getting a SkyLake rig if you don't already have Haswell.

yeah i think ill go that skylake route having my pentilum has bottle neck then just switching to skylake which will stop the bottleneck completly. I think i should go with a dual core i3 with some hyperthreading so its way less of a bottleneck. Yeah i wish they would hurry up and optimize sli and cfx so they did good but you can always take a card out and play on ultra/high 1920x1080 maxed out with a single r9 270x with 40fps+

thats the thing the pentilum use unrelvevent single core while the dual core still wont be enough but then i might only use one card for the time if i lose quality when skylakes hear ill jump on it then add my other r9 280 and it will be all good for like 3 yrs or more

Pentiums are bad for a 280. We don't even know what to expect with Skylake. I have a feeling it may suffer heat issues like original Haswell had. Get a 4690K and a Z97 board to accompany it.

A 3770k would be good, just make sure to get an LGA1155 Z77 board for it. I recommend the http://www.newegg.com/Product/Product.aspx?Item=N82E168... or a MSI/Asus/Gigabyte equivalent. A 3770K can overclock better than the 4770K but has 10% less performance at stock, but that is nothing a good overclock couldn't handle with good cooling. It doesn't suffer the heat issue that Haswell does AS MUCH, but it is still there a little bit.

aw it thought it had upgrading capabilities i want upgrades so if lets say i build my pc Q2 2015 it breaks down Q4 2015 and thats when skylake is there and reviewed kinda i can fully upgrade though having minimum performance boost it'll be better. I will get a closed water loop or i think a xspc 750 rayman( i think thats what its called) and watercool with that i know the risks but i can really effectively cool like that

I realized the whole time I was derping. Broadwell is the next series of CPU. 6th generation Intel Core CPUs are not really anything to talk about yet considering no information regarding Broadwell has even been released. If you are considering Skylake, you could be waiting until Q2-3 2016.

Thanks. Yes, it was originally budget and only one GPU and an Athlon X4 760K. Also mATX in the beginning. As my budget increased, I went FX-8320 and MSI 760GMA-P34(FX), then changed it to the ASUS M5A99X EVO R2.0 and got my case, then my other GPU, then got my 4770K! I will be getting an SSD right after I upgrade my RAM to dual channel. I am really REALLY wanting an SSD right now after being on TomsHardware.
