Core i7 7700k benchmark

[patrickjp93]

They get clicks that way. Journalism does have to be successful as a business at the end of the day.

[Zeeee]

My easily attainable 4.7ghz 6600k already gets 5700 and 16k so i mean decent gain especially cuz same chipset which i love so i dont have to replace my mobo when i wanna upgrade cpu...

I feel like that might indicate the opposite, actually. If someone were to fake this I don't think they would make that dumb of a mistake, so my guess is that the board is an engineering sample that got put under the Z170 name for some reason. IDK though that is fishy.

But the Z270 is also there

Right, so maybe the motherboard model is the name they masked it with because Z270 isn't public, and the Z270 thing there is taken from the chipset? The more I think about my argument the less sense it makes... maybe just ignore me

Z270 is confirmed. They get model from the BIOS.

The manufacturer can change the DMI string of unreleased products (in this case, the Z270 motherboard) to anything they want it to be. When programs such as Geekbench request the DMI string, it will display whatever name is attached to it. In this case, the DMI string of the motherboard is the Z170 SLI, but the chipset itself is Z270. 

 

Just because the two are different, does not make it fake. The score itself is also in line with a 4.5ghz chip of Skylake IPC, I've proven that already with my own tests. There is no 100% confirmation as to whether or not its real, but if it is, its performance is no different than Skylake, clock for clock.

Haha! See I was right and I totally knew that and stood by it the whole time...

People often forget that DMI strings are misleading. Look at my previous score. My CPU was clocked at 4.5ghz, yet DMI string says its 4.0ghz. For all we know, the 7700k in this benchmark could be overclocked, and we wouldn't even know it. People need to take things like this with a grain of salt.

For leaked info about a new tech product? More like a boulder of salt. A mountain of salt. Perhaps a moon of salt for Wccftech...

Yeah, there are quite a few of them now.

https://browser.primatelabs.com/v4/cpu/633138

 

Notice how low the scores are? Also, they are on ASrock Z170 Pro4 boards (or so the DMI string indicates). Either that previous 7700k score was heavily overclocked compared to this, or this score was heavily underclocked. Either way, this has gotten a whole lot more interesting.

Interesting, considerably higher score than the i7 6700k

Single Core:

i5 6600k: 5309
i7 6700k: 5822
i7 7700k: 6131

 

Multi-Core:

i5 6600k: 14568
i7 6700k: 19437

i7 7700k: 20243

 

i5 6600k: https://browser.primatelabs.com/v4/cpu/620296

i7 6700k: https://browser.primatelabs.com/v4/cpu/621525

i7 7700k: https://browser.primatelabs.com/v4/cpu/583064 (Same as in the main post)

 

Hopefully that'll mean some real world performance increases lol

Well... I'm sure we already figured this out by now, but if we take the turbo boost clock speed for the single-core scores:

 

6600K - 5309 / 3.9 GHz = 1361 per GHz

6700K - 5822 / 4.2 GHz = 1386 per GHz

7700K - 6131 / 4.5 GHz = 1362 per GHz

 

And the base clock speed for the multi-core scores (excluding the i5 due to no hyperthreading):

 

6700K - 19437 / 4.0 GHz = 4859 per GHz

6800K - 20243 / 4.2 GHz = 4819 per GHz

 

It's pretty much the same same score per clock, just a higher clock speed, making it really just a Skylake refresh. That's actually assuming that these results are accurate. It's still a nice respectable bump though, and I'm sure other parts like the iGPU will be considerably improved.

Question: Are the 7th generation i series CPUs going to be better enough versus the 6th to bother with if I already have a 6700K? (stock speed)

Not unless you want optane 3DXPoint or 10-bit H.265 encode/decode iGPU capability.

Idk what either of those are so I'm going to assume no then.  ?

 

Though if a 7th gen i7 would turn out not to be much more than whatever 6th gen CPU I might otherwise get for the mini-itx build I want to do eventually then I might swap the 6700K in my main desktop for a 7th gen i7 and use my 6700K in the itx build.

In terms of gaming performance, 5% improvement in CPU core clock speed is really not going to affect much of anything unless your CPU is the bottleneck, such as if you're playing at 1080p, which even then, it's not very meaningful. When it's not CPU-bound, then you might still see slightly higher minimum frame rate, but nothing really worth it.

 

You're going to end up paying another $350 for the new CPU, and if you want to take advantage of what actually matters in Kaby Lake, another $150 or so for a Z270 motherboard. Otherwise, the best price-effective option is, if you are using a Z170 motherboard, is to set the clock speed to 4.2 GHz and the turbo boost of the first core to 4.5 GHz. Even if you're using something like an H170, B150, or H110 motherboard that doesn't have the support for overclocking, there's little reason to spend so much for so little improvement.

I thought the 7th Intel CPUs were supposed to still use the 1151 socket?

 

Or you just mean that a new Z series chipset motherboard (Z270) would be needed to properly make use of a 7th gen CPU?

Nah, you'll probably be able to use the i7-7700K in a Skylake motherboard with a BIOS update. These processors should work just fine if so.

 

I'm talking about taking advantage of the other features of Kaby Lake, like native USB 3.1 and Thunderbolt 3 support, and more lanes provided by the chipset. Basically, some things that you might see that'll benefit newer motherboards.

Ah.  Ok.

 

But doesn't Z170 have 3.1 and thunderbolt 3 already?  I know my Gigabyte Z170X Gaming 7 does.

 

Unless you mean those will be on all Z270 boards and not just some like with Z170?

 

Sorry for my confusion.  It's almost 5am where I am so I'm a little scatterbrained atm.  (Thank you insomnia.  /s lol)

 

I should probably try to go sleep now..  >_>

USB 3.1 and Thunderbolt 3 already exist, but require an additional component on the motherboard. It'll be supported from the chipset, meaning you may see it on a lot more motherboards, including cheaper ones.

This sort of socket really need's a bump up to 6 Cores IMO. I feel like i have no reason to move from a i7 4790k on any of these CPU's for the 5-10% Performance Gain. They otherwise have a couple of nice things like thunderbolt and stuff but stuff that you can live without, My Board even supports NVME i mean really not seeing the point tbh.

Coffee Lake will be bringing that.

[VagabondWraith]

Does the chipset affect performance? Like, would I be better off with a z270 board and 7700K over a z170 and 7700k?  Or is the chipset different from actual CPU performance? Jw
