Differences between Skylake and Haswell

[DiamondRyce]

Been bouncing between Reddit and Forums but just wanted another opinion in the next week or so. Like I said before I am upgrading from a FX 6300 build to either Haswell or Skylake for gaming/livestreaming but I want to spend the least amount possible. I figured Skylake would justified its price but it seems like at most 5% difference between the two platforms. 

 

The only thing that I would find useful in Skylake is USB Type C since I recently bought a Nexus 5X earlier this month and plug directly into it. Also I would need to buy different ram even though I am perfectly fine with my 16GB DDR3 1866mhz ram. 

 

So if someone can help me compare Skylake vs Haswell that would be helpful. Thanks.

There is nearly no difference between the cpus ultimately...... BBBBUUUUUUUUUTTTTTTTTT the chipsets!!! Oh my "Ford" they are beyond different but haswell is still my top choice

So what does Skylake do in the chipset that Haswell doesnt. If its going to be socket how long is LGA 1151 going to last til the new ones? 

 

I know Haswell is dead in terms of the LGA 1150 socket so maybe still leaning that way.

The new intel cpu won't be out until 2018, 2017 at the latest and the chipsets really don't have much a performance difference other than faster data rates and ddr4 ability. Everything else is practically the same. The LGA 1151 line was just a side project for intel its just a slightly more powerful and more power efficient processor than the LGA 1150 line of processors.

[Clyne]

5-8% IPC increase

DDR4 Support

USB 3.1

Type C Support

More support for PCIE lanes(Different to Z97 and X99 with 5820K)

Lower power consumption

 

OP:If your on a budget, just get a 4790K. A OC'd 4790K will still be around a 6700K at stock or even overclocked.

Z97 platform with the 4790K is currently cheaper than the Z170 platform with the 6700K(also DDR4 RAM).

Ah thank you. The data rates and ddr4 are insignificant to me as I dont have the hardware for that anyway. I think I will just buy the Haswell then.

Well a 1x8gb stick of ddr4 is only around 40$ two is at 76$ or so

Thats the same amount I paid in total for the ram I have now. Like $30 like two years ago for 1866mhz and $34 dollars 3 months ago for 2133mhz... 

 

I know its DDR3 mhz is mismatched but all the timings are the same.

Haswell is by no means obsolete.  If budget is an issue it will be a cheaper platform offering almost the same performance, and you'll get to save a little more not needing to buy new ram.

[Lays]

The difference can be more than 5-8% depending on the setup, and Skylake offers much more "expandability" of your PC essentially.  If you run 2 GPU's, you still have the option to run M.2 SSD's and things off the PCH, which is really nice.

 

 

Here's a comparison between heavily overclocked DDR3 and heavily overclocked DDR4 as well, that I did myself

If you look at the "MEMORY" line, you can see the huge difference in bandwidth.

 

DDR4 @ 4000 Mhz C14-14-14-30 2T, AUTO secondary / third timings:

 

 

DDR3 @ 2800 mhz C9-12-12-17 1T, super tight timings for second / third timings:

The most useful thing to me there for Skylake is USB Type C and thats just for my Nexus 5x. 

 

IPC increase = Is not alot and probably wont affect me.

DDR4 = Well I do video editing but its mostly just for YouTube so slower encoding times doesn't effect me. 

USB 3.1 = I have a Kingston Hyperx usb drive that will support that but thats it. (I only have it because I won a giveaway) 

PCIE lanes = I use only one GPU, PCIE capture card, Xonar DG soundcard legacy pci and a wireless card.

Power consumption = Since I am coming a FX series, thats probably the other thing that I will benefit about.

Just get a i7 4790K, it's already cheaper if you don't factor RAM into the build.

If you need something way cheaper than a 4790K, Xeon 1231 V3 and H81 board is always a choice.

Thanks for the pictures. I can see the ram benefit in DDR4 but it doesnt warrant the price I guess thinking in my head. I was trying to keep this under $200. I might have to go used but I dont mind that. 

 

 "If you run 2 GPU's, you still have the option to run M.2 SSD's and things off the PCH, which is really nice"

Haswell has use M.2 SSD's correct? As I was telling the other person, I just run a single GPU. I dont like crossfire or sli as I utilize the other lanes for my streaming stuff, wireless card, capture card, and such.

Uh I was trying to keep this under $200 which was what I paid for my FX 6300 and Asus M5A97 R 2.0 board. An i7 would be nice but way out of my budget.

Yeah umm for 200 i wouldn't expect much...

Most of the time it's just a 50 dollar price difference(AMD vs Intel) for 1.2-1.8x performance increase.

Interesting, lots of good information. Maybe I should just held off the upgrade then. Or just play more optimized and less cpu bound games on stream til then.  

[branden_lucero]

if you plan to buy a Skylake processor that isnt the 6700K, then you'll be fine. a shortage has been having for months on that particular one, and prices are barely coming to a crawl to original MSRP. i feel that anyone who buys the 6700K at this rate is getting ripped off. unless you buy the 6700 and "force" overclock it with like an AsRock board that didnt get a bios update (or the processor getting a revision for that matter.)

Well i'd say just wait until the end of the year if you can. AMD's Zen is suppose to come out around that time with a 40-50 percent performance increase which would make it around Haswell-Skylake level, but it's all speculation right now.

If you can wait and save the money then that's great, otherwise Haswell is the cheapest option before it's discontinued from stores. 

I have the same motherboard as you, should be fairly easy to OC your 6300 in the 4.3-4.5GHZ if you have good cooling.

I have gotten up to 4.2GHZ on my 8320 but had to pull back due to thermal limitations(using stock cooler).

Thats the thing. I have not said any of my settings specs which I have been running since I got this build two+ years ago. 

 

Well my FX 6300 is already OC to 4.4Ghz on a Xigmatek Gaia (Think Original Hyper 212 cooler) 

 

R9 270 is OC 1100 Core 1450 Mem so basically stock R9 270x like what you have. 

 

16GB Ram is 1866mhz.

Been thinking about this as well. Cost wise, I feel would not need to overclock at all for some reason or maybe I just want a stable and quiet system. Idk.

Well i did overclock it to 1260 Core 1500 mem for a performance boost....

Mine causes a black screen issue when pushed over 1100mhz so I want more but I know my GPU should still be good after the platform upgrade.
