Intel Core i7-7700K "Kaby Lake" SANDRA Scores Surface

6700k annihilates Sandy in several games. By annihilate I mean the minimum FPS's are drastically improved. The 7700k will further increase this gap.

It's no longer 'cool' to harp on about using old hat sandy chips - they are now bottlenecking the latest GPU's.

I wouldn't say 'big differences', marginal incremental differences maybe, but it's not like P4 to Core2, that was a big difference.

I'm on a 2600K @ 4.4GHz, have been for what feels like forever now, and as a gamer I have absolutely no need to upgrade. There is no situation where my CPU holds back my GPU in a game.

http://www.techspot.com/article/1039-ten-years-intel-cpu-compared/page5.html

So why would I drop a packet on moving to a 6700K, new mobo, and new DDR4?

I don't believe for one second believe that we are at the limit of CPU tech. Fact of the matter is AMD have offered no competition, as such Intel have provided marginal IPC and clockspeed increases for the past few years. Meaning anyone on an older OC'd CPU isn't missing out on much. Had AMD been competitive you can guarantee Intel would have pushed harder for larger gains over previous generations.

Yes it seems like forever not much has happened in the cpu business for several years now. Stick with what you have until 6 core cpu`s become the norm.
 
It'll be similair to how it was with haswell to devils canyon. From experience of owning both a 4770k and a 4790k, the performance increase was tiny. 4790k did oc a bit better though.

To be honest, the man does tell the truth, as there was a decent benchmark suite that came out recently from one of the sites that actually did test i5/i7 generations against each other on a number of games.

SOME games, like IIRC Crysis 3, GTA V and Witcher 3 did benefit from some of the improvements on generations since Sandy, sometimes with a noticeable jump in average (and minimum FPS); albeit some games saw no improvements.

That said, a well clocked 2700K will still do pretty well. As it stands I'm holding off until Zen; the testing we've seen so far suggests its at least as Broadwell clock for clock, so a lot will depend on whether that holds true across a wider set of software to represent general IPC, and also what clock speed it releases at. Assuming that turns out to be true on release and clock speeds aren't too low, it won't be far off Skylake or Kabylake, with the difference being that AMD are intending to offer upto 8 core, 16 thread Zen into the mainstream market (although not cheaply I'd wager!). That increased core/thread count and an IPC boost (because Broadwell does have higher IPC than Sandy), with a decent clock, WOULD be worth considering an upgrade, especially if you use the system for other CPU intensive work not just gaming :)


If Zen at least turns out to be an interesting proposition, I think we'll start to see more interesting competition from Intel, either pricing, or new tech.

I don't have a problem with minimim frame rates or bottlenecking on my 980Ti in any of the games I play. I'm perfectly happy with Sandy until Intel release something that is more than a marginal increase over previous gens.

I know you love Skylake and I actually agree minimum frames are better but nothing else about it is going to tempt me to drop cash on it and Kabylake looks the same. I don't know if Intel have stalled because of lack of competition, shifting focus to mobile or technical limitations and eventually if Intel do enough generations of marginal increases it'll be worth while upgrading but the current pattern is overwhelmingly dull.

I think you need to define the word annihilate because I'm not seeing the annihilation TBH.

Yes a stock 6700k with very fast memory is faster than a stock 2500k with 1600Mhz memory but it's not huge a upgrade and an overclocked 2500k with 2000Mhz memory is faster. Overclock both chips and the performance is close enough not to matter.

Even if the 6700k was a drop in upgrade for Sandybridge users the £330 cost of the 6700k is questionable and at £500-£600 for the system upgrade makes Skylake and from the looks of it Kaby lake non starters.
 
Skylake does have a good IPC improvement over Sandy, but they are 4 generations apart, that's 4 generations to get a 15% IPC uplift.
 
Personally i think skylake is a good upgrade if your on something like an old X58 setup. Sandybridge onwards are all still pretty decent. In recent years ive owned the following.

3570k
3770k
4770k
4790k

Performance increase was pretty marginal tbh. Now settled on a 5820k, which tbh from a gaming point is a sidegrade from the 4790k. But with anything that makes use of the 6 cores, there is no comparison.
 
I don't see any point in upgrading to Sky Lake or Kaby Lake.

What i need is more threads, not a marginal IPC gain, that makes no beneficial difference.
Even DDR4 is still only Dual Channel unless you get a Broadwell chip, Dual Channel DDR4 is not really any faster than DDR3 unless you get 3200Mhz RAM and even then the gain is not much and sporadic.

Increasingly 4 threads without HT is not enough, or the CPU is highly stressed trying to pack a lot of instructions which would normally be spread across many more threads into just 4

This includes games.

Hopefully AMD with Zen will say "actually 4 cores 8 threads is the new i3, 6 cores 12 threads the new i5 and 8 cores 16 threads the new mainstream i7"
 
I'd say for anyone with a P55 quad core i7. X58 users can drop in a 4.2Ghz 6 core 12 thread Xeon X5650 for £70 and that system would give a 6700k run for it's money/spanking.

If core/thread usage does improve humbug, (which id like to see too). In your situation a switch to a 4770k/4790k would be a good move. They can be had quite cheap now. Personally im done with the whole cpu upgrading thing now. The 5820k will last me a good few years. Id only change if i could source a decent clocking 5930k. Even then thats only if i went sli. Which tbh on an older non DX12 card such as my 980ti is perhaps a bit pointless now.

At what resolution though? For cpu testing and to see any difference they will often run at 720p or even lower yet show absolutely no difference at 1080p/higher settings or higher resolution.

The 5820K is just what Intel should have been doing as par for corse.

I know i will benefit from an i7, and yes a Haswell/Devils' i7 used is about £200.

Its still a lot of money, at this point i would rather wait for Zen, maybe my Board, RAM and 4690K will go a long way to a DDR4 6 core 12 thread setup, hopefully its enough to buy the chip, then i only need to explain the board and RAM to my bank manager. :o

Iirc i sold my 4790k, 8gb of 2400mhz ram and a pretty high end Z87 maximus 6 formula for circa £300.00. Added £100.00 to that money and purchased a 5820k, msi X99 mpower board, 16gb of 3000mhz ram and a 128gb pcie ssd. The ssd i sold for £37.00 as i wasnt using it. So all in all it was a pretty cheap move to X99.
 
I'm thinking at this point my stuff is worth at least £250, maybe?

Gigabyte Gaming 3 Z97.
4x4GB Hyper-X Savage Red 2400Mhz.
4690K.

Total cost was just shy of £400 new.

Its 8 months old.
All original boxes ecte, unused reference cooler for the CPU.

You could do a MM price check. I think you're looking at around £180 for the bundle.

Charlie's hilarious take on Kaby:

Sarcasm detector needed to fully enjoy.

According to him Samsung vastly outstrip Intel in 14nm tech too:

Intel just knocked one out of the park with their stellar new 7th generation Core processor aka Kaby Lake. SemiAccurate knows that this new CPU line will only speed up the innovation train of Intel silicon.

And then goes on the say that again in a more long winded way, still with no context or even the slightest hint on what has him so excited.
