Intel Skylake / Kaby Lake

[SelenaGomez]

Ok so my computer died and I was forced to buy a 6600k and z170 board. I was upset because i wanted to wait for cannonlake etc but I coulnt go without a computer. So with these results I shouldnt feel so bad correct? The cpus coming out in January arent much of an improvement over the 6600k correct?

You aren't losing anything worthwhile. KL isn't much different from SL.

Unless you're keen to overclock - 5ghz on air sounds good to me.

Yeah I just purchased a i3 6300 and a Asus Z170s Sabertooth motherboard from newegg for the early black friday sale last night , for an HTPC for the living room to replace my AMD 5370 . I plan to upgrade the cpu to a 7700k on this motherboard if its going to be compatible. What I want to know is,is this cpu going to be strong enough to encode from DVD to MKV and maybe do some minor gaming? Also I bought Crucial DDR4 2400 so will this work ok with this setup?

~10% more out of the same core seems like a pretty good job to me.

? People were able to overclock their 6700k's by 200Mhz over a year ago, when Skylake launched. I'm 100% sure that every 6700k ever made can do 4.2Ghz base clock and 4.5Ghz turbo, so I don't think the 10% from increased clock speeds is impressive at all.

As I've said before, all that matters is how far it overclocks. If the average 7700K can do 5Ghz on air then I'll agree it's an impressive improvement in terms of 14nm process optimisation.

Why buy into old, used technology, especially if your endgame is to get a 7700K? (which is what your post indicated)

DDR4 is likely to be portable to a next gen system; you're at the end of the line with DDR3 (unless your next stop is used Haswell/Z97). 6700K is also faster, supports more threads (as games become more threaded, this will be useful), and comes as part of a more modern platform (PCIe 3.0, NVME, etc.).

I ended up going with an i3 6100 OC'd to 4.5Ghz w/ 16GB Ram - I can now play BF1 on ultra settings at 1080p at a solid 60Fps.

The whole upgrade cost me less than a 6700k and now I can just drop in a 7700k in the future and reuse my mobo / DDR4 RAM. Dead happy with the upgrade.

Some BOINC project tasks are memory-bound. This is extremely visible on Core2-era quad-cores, due to the lack of an IMC, even though they support dual-channel on the chipset memory controller.

If you are looking for synthetics, consider the SPEC "Stream" benchmark, which I have read is primarily a memory-bandwidth benchmark.

Not everything in the computing world is gaming-oriented.

I am looking for non gaming comparison multichannel vs single channel with a significant in improvement to prove your point, can't find any Proof?

Here is one article with a variety of tests. The results are mixed will dual channel doing a bit better than single. I was looking for Spec FP comparisons between single and multichannel, since FP operations can be very memory intensive, but haven't had luck yet. Since I'm not a fan of gigantic posts, I'll just provide the link: http://www.gamersnexus.net/guides/1349-ram-how-dual-channel-works-vs-single-channel/Page-3

That looks like a good CPU-Z score.

Yes I already posted that link above. The topic is does multichannel memory give a significant increase in performance, no.

So to be clear, they changed the socket again right? I will not be able to just swap my 6600k for a 7700k in my asus z170-a?

Same socket. Only need a BIOS update (in most cases).

Ohhh so i wont need to change any hardware but my cpu if i want to upgrade my cpu to the latest ones coming out in January?

I don't understand this line of thinking. May as well just buy the 6700K in the first place and not worry about peddling the 6100 on eBay 2 months from now and hope you don't get scammed.

In reality, I probably won't upgrade now as I have no need to until i get a higher res screen as what i have seems to run just fine on max settings / 1080p for the games i play.

I originally assumed i'd need a powerful i5 / i7 for BF1, but it turns out i don't.

Higher resolution will bring down your framerates (GPU intensive), so your need for a faster CPU will actually be diminished when/if you transition to a higher-resolution screen.

Nevertheless, I have to agree with jpiniero -- if your endgame is to go with 7700K, why didn't you just get a 6700K and call it a day for the next 3-5 years?

Looks like this was posted by a TweakTown editor. Review samples are apparently out!

My end game isn't to go with a 7700k anymore as my OC'd i3 is good enough for what i need - literally, it isn't bottlenecking any tasks i throw at it.

I will likely upgrade to a 4k monitor next, so i'll do a GFX card / processor upgrade then.

I will see no benefit upgrading to a 6700k or 7700k at this time, so logic dictates that i defer that upgrade to when it is necessary (when? who knows) at which point it will be a cheaper upgrade.

It's like buying a Bugatti Veyron for it's max speed, but you'll only stick to the speed limits on public roads. No point, no need - unless you travel to the autobahn.

Makes sense to me. Enjoy the i3!

Why were you even considering an I7, if a I3 is enough for your light computing needs? Also please remember that there are definitely use case scenarios to fully take advantage of a quad core CPU, such as the 6700k or 7700k. Just because you don't require it doesn't mean others don't!

I'd love to know this too! Then again I won't commit to upgrading my 6700k until we see if non cherry picked retail samples are capable of it too

Yes, ~10% more speed from the same core sounds good to me. I consider that a good optimization from Intel. 4.5 + 10% is about 5.0 give or take. You just said that would be impressive.

That would be about 4.6 base and 4.9 turbo overall.

 

[SelenaGomez]

IMO a 10% increase in speed is not something to brag about and is not a good upgrade. Many have been conditoned by the money hungry corporations to think that 10% is a great worthwhile upgrade. Its not. And its those people who are the reason why we are only getting 10% increases every year or two.
