Good time to buy a new laptop.
We need new Nvidia laptop gpu's for these cpu's.

It crushes it, as to be expected.

No power / battery test? Always needed for testing a mobile platform / chip, at least IMO.

Plus there are two other chips clocked significantly higher, and one has 3Mb more cache.

I see that there is an 8400H also, which is a 4C8T mobile chip.

I'm sure that will come later.

 

[LTC8K6]

So we do have new mobile i5 chips that are 4C8T instead of 6C6T.

Yeah. Remember that the i7 H models have the L3 cut to 9 MB already so there isn't much more to cut.

Power consumption is definitely higher on the 6 core H, about 15% according to NBC.

NBC also said the power consumption numbers might change.

Note: Although power consumption values appear on the higher side at the moment, they are also largely dependent on software optimizations at the firmware and OS level. Values may change as vendors release software optimizations over time.

You can't have 2 more cores for free, of course.

Wow. VERY nice turbo speeds. The highest clocked one even has higher single core turbo than the 8700K desktop chip.
So Intel is ahead in the mobile "core wars".

 

[epsilon84]

About time, the 7700HQ is getting pretty long in the tooth now. Better MT performance aside (which was a given) the gains in gaming are significant in some titles and somewhat surprising. Always thought that a 7700HQ was sufficient to not bottleneck something like a GTX 1070, clearly that isn't always the case as the benchmarks show.

It's TVB - Thermal Velocity Boost.
It's above Turbo Boost.
https://en.wikichip.org/wiki/intel/thermal_velocity_boost

i9-8950HK Turbo Boost 2.0 is 4.3 on six cores, 4.6 on 1 core, and TVB mode is 4.8 on 1 core.
TVB might be 4.7 on all cores, but I only saw that reported in one place.

 

[Bouowmx]

Isn't Thermal Velocity Boost kind of pointless on the i9-8950HK? The multiplier is unlocked already.

From a news release:

The Intel® Thermal Velocity Boost feature is supported on Intel® Core™ i9-8950HK and Intel® Xeon® Processor E-2186M and is designed to increase performance of both multi-threaded and single-threaded workloads. The maximum Core Frequency is achieved while the processor is at a temperature of 50°C or lower and turbo power budget is available. Frequencies may reduce over time as processor temperature increases.

By miracle (since in reality, cooling and power will not be sufficient), the Xeon E-2186M can do 4.5 GHz all-core with Thermal Velocity Boost.

 

[LTC8K6]

Isn't an unlocked multiplier a bit silly on a mobile chip? The thermal headroom is unlikely to allow much of a gain.
I'd rather have an "unlocked" version of TVB that can get to whatever it can get to...

Unlocked TVB on a desktop chip, where the better the cooling, the further TVB goes up the core/clock/multiplier ladder?

But then how would that be different from TB2?

Looks like a win for Intel. All the big players seem to be releasing top laptops with this chip as soon at the same time. It makes a market splash.

Raven Ridge is great chip for laptops, but it never really made a splash when released.

Yea, despite all the criticism heaped on intel for lack of progress, the gains in mobile cpu performance have been really very good.

Currently, Turbo Boost 2.0 is not temperature-opportunistic. Assuming unlimited current and power, from cold bug to throttle temperature (100 C), Turbo Boost frequencies are the same.

Thermal Velocity Boost would be useful for lower-power desktop processors, like i5-8400, in which the power output does not overwhelm the IHS TIM.

 

[hasu]

Is there a faster version of 8700k as well?

 

[ondma]

Is there a faster version of 8700k as well?

Yea, overclocked to 5ghz!!!
Seriously, not at the present time, although there are rumors again about an 8 core version, which of course would be faster in multithreaded loads but might not clock quite as high.

 

[jpiniero]

Actually watching the video, it does seem like the main difference in games is the additional turbo clock over the 7700HQ and the faster stock DDR4 speed.

Not at all. DTR's can overclock quite well!

nah i think dedicated gpu's on a laptop is kinda moot now.

Best to have a thunderbolt or a type C port and have a external gpu if and when you do intend to do that gaming.

Otherwise the dedicated gpu = extra stuff on the laptop to make it more expensive, less room for a larger battery, and ultimately makes the thing hotter because there is more things that heat pipe needs to cool.

I bet a lot more people will choose dGPU in the laptop over the Thunderbolt GPU box.

Time for a faster Thunderbolt!

Probably those that don't know about eGPU's.

I dont see the point in a dGPU over a eGPU now.
You really cant game on battery power. The thing will last you what? 25-30min on battery.

You can get a eGPU up to a Titan XP if you wanted.

I know about eGPU, but wouldn't get one.

1: eGPU is a lot more cumbersome to take with you, or just move to another room in your house.
2: eGPU box + GPU card is more expensive than just getting dGPU.
3: eGPU performance is worse than dGPU performance.

From my perspective, and eGPU box is worse in every way that matters, and I bet the vast majority will see it that way as well.
