You'd have to isolate CPU power consumption then, how many reviews have you seen do that?

Toms is the last major site which did this, for some odd reason they've stopped doing so!

I thought it was interesting how Anandtech's pre-review saw some anomalies in a few games where the i5-8400 trounced the i7-8700k. Both Rise of the Tomb Raider and Grand Theft Auto 5 saw some rather odd numbers at 1080p. They saw...

RotR-1
i7-8700k: 100.45
i5-8400: 112.43

RotR-2
i7-8700k: 93.73
i5-8400: 121.73

RotR-3
i7-8700k: 116.36
i5-8400: 141.48

GTA5
i7-8700k: 90.14
i5-8400: 98.16

The other games didn't see a spread like this, and it wasn't nearly pronounced at higher resolutions (due to GPU limitations), so it's interesting to see how some games see a lead like this. I'm assuming it's due to the game using HT "cores" instead of physical cores. I checked ArsTechnica's write-up, and they saw the same low maximum framerate in Rise of the Tomb Raider. So, it's likely something that we'll see fixed sort of like what happened with Ryzen.

Yeah, I mentioned that on the last page, but no one took notice.

IMO this is the biggest reason I want an unlocked multiplier. This was probably some kind of bios anomaly that killed the Turbo frequency.

Tom's test included the OC'd scores and the 8700K pretty much ruled everything.

Set it 4.8-5GHz and you don't have to worry if Bios is going flake out on turbo frequencies.

 

[JoeRambo]

Yet another disappointing "initial data" preview from Anandtech. I mean this is consumer computing shift, on the level of Core2, Nehalem quad, Ryzen, and we get this junk article? I don't even want to point out what is wrong, just reading their sister site THG review should be enough.

 

[LTC8K6]

Yah definitely something going on with Tomb Raider and 8700k!

Looks a bit like reversed results...

 

[PhonakV30]

according to WCCFtech , 8700k Oc reached 92 degree .time to delidding Cpu !!

 

[Elfear]

Would you prefer a 4K graph showing all the CPUs being GPU limited instead? 720P testing shows the relative strengths of the CPUs without GPU bottlenecking. This will become more relevant as GPUs get faster, if you run a multi GPU setup, or if you are a single GPU user willing to sacrifice some graphical detail in order to maximise framerates for 144Hz or even 240Hz gaming monitors.

That's a big maybe. I'd rather review sites just test those scenarios rather than try and extrapolate what SHOULD happen based on the results of a super-low resolution.

 

[moonbogg]

Seems like a paper launch. Best thing to do is forget about these things for a few months IMO.

This or there actually is an issue with HT which the 8400 lacks.

 

[DrMrLordX]

I see that only HardwareCanucks did Overwatch tests:

I wonder how much time they put into that round of testing. For when 260 fps isn't enough!

I'm going to mod - mod - mod - mod - mod my cooling system. Please don't report me, can't help the stutter.

It's okay, Max, we won't hold it against you.

.... plus you get more women!

Definitely not enough Gamer Babes around.

Can i get laid with an i3-8100?

Maybe in foreign markets where those chips have more cachet.

What if you have 8700k in your rig but the gamer babe is an amd fangirl?

Wait. AMD Fangirl Gamer Babes? Where?!?!?

As far as the power consumption numbers go . . . why is anyone surprised? Take the CPU power consumption of the 7700k and multiply by 1.5x . There you go! It will pull down some pretty serious juice when overclocked. The 8c chip should be even toastier. Though I am genuinely surprised by the supply issues.

Have a few drinks. Everything follows a bell curve.

I wouldn't go that far. It's the same old cores on the same old memory platform using the same old die process. There just happens to be two more cores to make 6. We had consumer level hex cores in 2010 with the 980x. If anything, this isn't much of an advance at all.

I wouldn't really classify the $1000 extreme edition HEDT CPU as consumer level. Available to consumers, sure.

The first real "consumer level" 6 core was probably the 5820k, but the platform costs made it out of the reach of many consumers still.

A sub $200 6 core on an affordable mainstream platform is definitely a big shift for Intel.

 

[epsilon84]

That's a big maybe. I'd rather review sites just test those scenarios rather than try and extrapolate what SHOULD happen based on the results of a super-low resolution.

Which part is a big maybe?

Here are gaming benchmarks with a 1080 Ti, complete with frame time figures:
http://techreport.com/review/32642/intel-core-i7-8700k-cpu-reviewed/6

8700K is a beast for high fps gaming - provided you have a fast enough GPU to power it.

 

[eddman]

I'm getting quite disappointed with a lot of these reviewers. How hard is it to clearly mention the maintained turbo clocks under benchmarks? This is some really needed info.

The results seem to be all over the place. Based on what I can see and guess, some reviewers' board's turbo apparently did not engage properly and caused low scores, some of them were locked at 4.7, and some were either at 4.3 or 4.4.

Yes, not as major as Core 2 and nehalem, but it's intel's first non-HEDT more-than-4-cores consumer lineup. That's still big.

 

[VirtualLarry]

We are not even halfway through day one...

You sure bail out easy...

LOL. Not sure what you mean by "bail out". I've already ordered an i3-8100 and ASRock Z370 ITX/ac board. I think that qualifies me to be in the Coffee Club. Though, I don't expect to be given a key to the 8700K Owner's Washroom.

 

[VirtualLarry]

Also according to power draw tests from Computerbase.de Core i3 8100 draws LESS power than 35W TDP Core i7 7700T.

Sounds like I made a good choice of processor for an ITX / HTPC / router box.

 

[coercitiv]

So, with snapshots like these can we finally acknowledge people who argued for more cores in gaming were actually on to something?

 

[Glo.]

Im pretty sure that 8100T at lower voltage and lets say 3.2 GHz will be truly 35W TDP CPU, if 8100 has power draw of 55-60W under load.

 

[WildW]

Has anywhere bothered to review the i3 8350K? I know today is all about hex-cores but isn't this basically a cheaper 7600K with more cache?

If I didn't know better I'd look at the 8MB cache on the i3 vs 12MB on the 6 core i5/i7 and think they were harvested from those, but as far as I know Intel have never done that. Or is it just a consequence of a modular design?

 

[Bouowmx]

There is a dedicated 4-core die, Core i3 is not cut from i5 and i7 6-core.

i3-8350K price looks really bad next to the i5-8400. Nevertheless, here is one review: https://www.computerbase.de/2017-10/intel-coffee-lake-8700k-8400-8350k-8100-test/

In that game, anyway.

 

[Glo.]

There is a dedicated 4-core die, Core i3 is not cut from i5 and i7 6-core.

Same die as Kaby Lake Core i5 and i7, but reengineered for 1151v2 socket, and made on new process, hence the power savings of Core i3 8100 vs 7500 and 7600 SKUs.

I've been wondering too, if the CFL quads were really harvested hex-cores. Anyone feel like delidding an i3-8100? (Preferably, not me... I need this one working for a build.)
