[Various] 6-Core Coffee Lake Lineup: i7-8700K & i5-8600K / Official Reviews & Benchmarks (Update 19) - Page 240

post #2391 of 6247
Can someone disable HT on 6 or 8 core CPU and run some game benchmarks with 6 cores with and w/o HT to compare results. IMO 6 real cores will act at least on par if not faster on the same platform and frequencies.
There are many examples where 4 threads are bottleneck but not sure 6 real ones will be, especially considering 5+Ghz OCing capabilities...
Edit:Can run some benches but in at least 6-7 hours from now.

This is all you need for that:

2600k demolishes 2500k in a ton of games, like nearly 50% ahead. Yes of course 6c is going to last longer than 4c, but with the ever increasing thread counts and ryzen exisiting i am not comfortable suggesting 8600k when 8700k is only 100 bucks more.

Just remember at sandy bridge launch, you would be hard pressed to find ONE game where 2600k was above 2500k. i5 used to be the best choice, times have changed and now it isnt.

Not 100% cool with that. However, I'm buying it anyway because my Haswell is getting pretty dated paired with my GTX 1080 Ti. I have been spending all my money on GPU upgrades as that has been the best bang for my buck.

The true rip off to me is going to be buying 16 GB of fast DDR4....

What happens is that the i5 Skylake and Kabylake were released by U$ 243. The i7-8700K got a bigger bump of almost U$20. But I am OK with it, because I feared it would be close to U$ 400 (and they are still below Broadwell price)

The i5-8600K will come ahead of the i7-7700K by my calculations. If you overclock it, it will open even more because we are talking about real cores, not threads. But if you intend to keep the CPU for several years, better invest in the i7-8700K. But if you don't have money, I don't see the R5 as an option unless you are gaming in 4K and the bottleneck will be on the GPU, but even then I think the i5-8600K is a better option for games, especially if you already have a water cooler to take it to 4.8Ghz without delid.

Just to be clear, if all you are going by is launch benchmarks then yes of course 8600k will be ahead of a ryzen 1600......so will 8350k in a lot of titles.

But of course, that is not really what is being discussed.

And now there is just a remaining question. Why all these benchmarks shown the same single core speed as 4.5 GHz CPU? Also Intel, stop selling overclocked CPU, you are depriving overclockers of fun.
post #2397 of 6247
Well in reality 2500k-4770k were "underclocked" tongue.gif

I know what you mean tho, not much fun overclocking 300mhz when i had a 1ghz overclock on my 2500k. Same thing with GPU's, oh boy a whole 100mhz, i dont even bother with GPU's anymore.

As for leaked benchmarks, im convinced its down to memory. I would blame it on turbo boost 3.0 but skylake x has that and the scores look normal at stock speeds.

You see i learned my lesson getting a 2500k, i am sharing my experience with people and am somehow getting called out as a fanboy for it! Had i got a 2600k originally i would not have upgraded to ryzen, and i would be on the fence about coffee lake.

Spending just that little bit more on CPU goes succccchhh a long ways, it really does. This is not as true for GPU's.

Because being a PC gamer core count is all that really matters to me. Hence the reason kept upgrading my gpu while keeping my Haswell from 2013.


I get why people love the I7 for anything besides video games thru. What really affects right now is my 1080 ti is bottlenecked to all hell.

Take this screenshot showing how badly the GTX 1080 TI gets bottlenecked with even the latest CPUs and RAM:




The 97th percentile number is the one I care about most when playing games because that's what you can feel the most.

My Haswell with ddr3 is the bottleneck. The 1080 Ti is too powerful for anything made in 2013. I knew this was going to happen someday anyway.

Right now the plan is to overclock the 8600k to 4.8ghz as the rumors all suggest it hit easily that and maybe go with 16gb of G.SKILL TridentZ DDR4 3600.

I wait for the official reviews and plan to take a very close look at all the game benchmarks pairing it with the 1080 Ti.

Did you happen to click on the link i posted above? Its gamers nexus testing the 2600k in 2017, it is head and shoulders ahead of the 2500k in a good amount of games. You seem to have the same mindset as someone buying a cpu in 2011, where i5's were the bargain because you saved 150 bucks and almost no games benefited from those extra threads. Not only is this starting to happen today, but there is now only a 100 dollar price hike from the unlocked i5 to i7, going forward we will be seeing more and more games take advantage of exra threads not only because of intel, but because of ryzen being on the market (amd is currently outselling intel in desktop cpu sales).

Ram can make a difference in games of course, but it does not being to compete with the FPS loss you can experience by not having enough cores that the game wants to make use of. Keep in mind again, launch reviews of coffee lake only tell part of the story, the real answer is going to happen a few years down the road.

I think intel intentionally priced 8600k and 8700k so close, they know where the market is going and this is their way of saying "buy this, not that".
