Intel Coffee lake - Worth to wait?

[Alcatraz]

So i sold my pc and currently using my 2 years old laptop right now. Im planning to build a PC but with intel CPU not AMD's because i only gaming and ryzen is not pretty good at gaming which's sucks. So, my choice is: Get the I7 7700k, or wait until august for intel coffee lake to be released?

Wait for coffee lake, the mainstream i7 should have 6 cores.

Wait fot i7-7740k. It will take crown of best gaming CPU in the world in less than a month.

[Radioaktivist]

Unless applications use 6 or more cores its a waste of money. By the time this power is required the price dropped several times

[CursedPanther]

If you really have to ask such a question, then I'd say you can wait.

Only difference is quad channel RAM and no iGPU. That isn't going to be worth the cost of the more expensive platform if you're only gaming.

I personally wouldn't bother with Intel Coffee Lake, due to the tick/tock cycles.

It's pretty much 6-cores:
- Reduce the core size
- Reduce the iGPU size
- Remove hyper-threading capabilities
- Increase its die size to accommodate six cores

Thank you all for your comment. It is settled, i will get nvidia volta and coffelake in my next pc build

A 6 core i5 could offer better gaming than the a 4 core i7.

The purpose of hyper-threading is to use the idle time of a core when it is in a wait state. Consequently HT doesn't double the core's throughput but only increases it by 25-35% at high load. So a 4/8 cpu is roughly equal to a 6/6.

In theory, doing the maths bassed on Passmark scores, a 6-core 7600k could be 14% better than an i7-7700k multi-threaded. Then if the clock was boosted to i7 levels, it could be 23% better. Without boosting the clock it might not be as good.

As intel wouldn't be rushing to bring out new cpu's without a reason, it is probable there will be a performance boost of some sort or better pricing competitiveness against ryzen.

However, unless you buy a 1080 ti, or the ti-p if that materializes, the chances are that the gpu is the component that governs performance in an i7 system.

You've forgotten the most basic requirement, which is the game will have to be programmed to make use of all those cores and threads in the first place. Yes a hexa-core CPU will always win the numbers crunching contest i.e. benchmarking over a quad-core, but may not provide any meaningful boost when it comes to gaming.

I'd say yes. Ryzen is already pushing multi-core gaming, so by Coffeelake's launch 6 and 8 cores will be normal. Heck, we may even have Zen+/Zen2.

Then again, that may take longer than we think, so a 7700k is still good.

Minor correction here but Intel doesn't do tick/tock anymore.

Sure they do; SkyLake vs KabyLake is a tick/tock example

How do you figure that? All we have is tons of benchmarks showing the opposite and an ID-tech interview that reeks of a paid commercial. XD

Well thanks for the correction.

However, in that case: Process, Architecture and Optimization Strategy

Broadwell (process) > Skylake (Architecture) > Kaby Lake (Optimization)

(I personally ignored and skipped Broadwell as a mere stepping stone, assuming it was still using tick/tock cycles, opting for Skylake - Kaby didn't offer much in the way of gain unless on a Laptop, with better GPU and battery saving, etc)

Then repeat...

Coffee Lake (process) > Cannon Lake (Architecture) > Ice Lake (Optimization)

???

They do say that Cannon Lake will co-exist with Coffee Lake however, and I don't have any specs on it currently (except that it's a 10nm chip).

EDIT:

Actually it would be...

Haswell family: Haswell (tock) > Haswell Refresh (Devil's Canyon - refresh) > Broadwell (tick)

Skylake family: Skylake (tock) > Kaby Lake (refresh) > Coffee Lake (refresh) > Cannonlake (process)

Icelake family: Icelake (architecture) > Tigerlake (optimization) > ??? (process)

Sorry was still getting my head around the reordering without using tick/tock anymore.

Coffee is another refresh, after the Kaby refresh (which confused me). Then it starts over with Cannonlake.
