Broadwell-E thread - Page 97

post #961 of 7252
Hey guys. I'm starting a new build and planning on using a BW-E chip. I've got some questions though, and be prepared because they're kind of "loaded" questions! tongue.gif

So, first things first. I've looked into benchmarks and saw that the 6700k is faster than something like the 6950X in single thread tasks. Is that simply because of the clock speed difference? IE, if I were to overclock the 6950X to 4.0GHz, would it perform about the same in single threaded tasks? Or is there something vastly different between these two CPU's that would make that scenario untrue?

Second, does anyone have any idea as to what temperatures I could expect on a 4.0GHz overclock? I'd like to keep voltage down as low as possible, and I'll be using a 360mm radiator.

Lastly, I'm trying to figure out which CPU is best for my needs. I'm most often gaming, but, I very often also record, stream, and have several other various software running in the background. I was thinking perhaps the 6900K. Seems like a good value, with 40 PCI lanes and a decent clock speed out of the box.

True, I just had my eye on a set of 32GB 2800Mhz Corsair Vengeance LPX (14-16-16-36).
Don't know which ram to get honestly, there isn't an abundance of lower latency higher frequency ram here, so slim pickings.

I know it's a bit of a side grade, but remember a few months ago on the Haswell-E thread I was going to build a new machine and give the wife/teenagers this one, so tossing up which CPU to get myself or them.
The teenagers are doing Film and TV, which requires a lot of video editing, also gives me a reason to buy some new toys..lol.

Yeah it's partly due to the clock speed (6700K can hit ~4.7-4.8ghz, broadwell sticks at ~4.3ghz mostly), but there IS a couple percent better IPC gained on Skylake over Broadwell (maybe 3-5% at best if that) so it does have a TINY gain over Broadwell even in single threaded.

However, there ARE many advantages to having Broadwell-E over the Skylake 6700K. You get quad channel memory which doubles your bandwidth (and you can have up to 128GB of RAM if you need it), you get more cores (obviously, since even the lowest model of Broadwell-E the i7 6800K has 6 cores) which more and more programs and games etc.. are taking advantage of. You get more PCI lanes so you can install a lot more stuff. (the i7 6700K only has 16 lanes, meaning installing two graphics cards takes up ALL 16 lanes! So you can't install ANYTHING else if you have two Graphic Cards in a 6700K system. Whereas the i7 6800K has 28 lanes, so you can have two cards and still have 12 lanes left for three PCI x4 devices like M.2 or PCI-e NVMe SSD's like the Samsung 950 pro, wi-fi cards, etc..etc.. And you can even have THREE graphic cards and still have four lanes left for one M.2 or PCI-e SSD)

And for things like video editing and rendering etc.. the 6800K will STOMP the 6700K. Plus in games like Total War: Warhammer, Battlefield 4, Crysis 3 (to a lesser extent but still there) you WILL see an improvement with more cores. Total War games for example will use ALL 16 threads of my 8 core hyperthreaded i7 5960X and actually gets more FPS than on a 6 core, with a 6 core getting SIGNIFICANTLY better fps than the 4 core 6700K does.


Honestly it really depends on what you do how many cores you need. If you do a lot of streaming and video editing etc. .and similar stuff then 8 cores is entirely usable for you. Although you won't see any improvement with the 6900K over say the 5960X; and you can get a 5960X on like amazon for as low as ~$730 currently, which is a better deal in my opinion (https://www.amazon.com/gp/offer-listing/B00MMLXIHM/ref=dp_olp_used?ie=UTF8&condition=used) whereas you're spending $1100 for the 6900K, and it's literally identical since the 6900K can only hit ~4.3ghz on average compared to 5960X's hitting ~4.6-4.7ghz at times, which makes up for the small increase in IPC that broadwell has..

So anyway...

Quick comparison here between SM961 in the M.2 port and PCIE x16_5

Wow...nice! Thanks for showing those. I had no idea that M.2 vs. PCI could actually make a difference at all, let alone a somewhat significant one in a couple categories. Specifically that ~450mbps difference in sequential read speed is surprising to me.

And you can even have THREE graphic cards and still have four lanes left for one M.2 or PCI-e SSD)

That part is not correct. z170 has an additional 20 PCIe 3.0 lanes on the chipset that can manage secondary peripherals and M.2 drives outside of the main x16 lanes on the CPU.

The one that ships with the ASUS Deluxe II. On the Deluxe, PCIEX16_3 shares bandwidth with the M.2 and U.2 ports, which is where my GPU is currently residing - so the contrast there may well be due to this. Just thought I'd post it regardless lol.

Why on earth would you put GPU and fast SSD on the same PCIe lines? Come on tongue.gif Is that some awesome ASUS design?

You don't, at least not primarily. PCIEX16_1 is the optimal slot for the GPU, it was just easier for me at the time due to tube length. The lanes are the most direct path to extract the kind of performance most people will be wanting. Only so many slots to go around on a feature rich board like this
