From 5 years to 2 years. So they are catching up according to you
I will not deny that I underestimated TSMC's capabilities by a little bit XD. So back in 2014 or so and maybe early 15, based on how long TSMC took for 28->20, I thought TSMC would take a long time again, but apparently they learned a lot from their very long 28nm node. But what I view as the difference is that when I see evidence for something else, I will update by believes, I don't have an emotional stake in any of this. I am interested in the facts, not in being right ("winning" the discussion) per se .

Witeken. Its the entire idea of beeing first that is stupid. It might be easier to recon now than 4 years ago

We have seen the money go to mobile and that naturally changes who have the benefit of beeing first.

Its imo important to evaluate

1. If the plans made and presented 5 years ago was in alignment with what happened and was needed

2. Execution of the plan

We have seen capex reduction and adaption from Intel years ago. And rightly so it seems ! On the contrary samsung have been pouring more into the process poll and ofcource it shows. All as expected.

But Samsung process is imo still stuck in a bad place and they need a long term solution.

As mentioned earlier, the GPU sees a significant shift as we move from a Mali T880MP4 to a Mali-G71MP8, which essentially doubles the number of shader cores employed. HiSilicon decision to go with a wider GPU on the same process node was undoubtedly made much easier by the new G71's much better die area efficiency. The new GPU runs at 900 MHz, the same as the older SoC. The combination of doubling the shader cores over the 950 and moving to a new architecture over the 950 results in a 180% increase in the GPU's performance compared to the Kirin 950. As a result, Huawei is positioning the Kirin 960 directly above the other high-end SoCs launched this year (though we expect the other SoC vendors to also have respective increases with new generations soon).

Mali-G71MP8 @ 900MHz: >50 FPS @ Manhattan Offscreen / >100 FPS @ T-Rex Offscreen

Even a 2.4GHz A73 with a beefed up memory controller and more RAM bandwidth is only hitting 2K in GB4 ST.

At less than 1,3W... you have to take that in mind. They are more efficient than the Apple A10 Fusion cores.

The new mali gpu has extremely impressive performance. We can expect galaxy s8 to have mp16(16 gpu cores) which should put it >50 % more performance than a10 from apple. Was not expecting such a big jump from ARM at all.

So what?
Who needs more in a phone anyway. Its a crazy high score for a 2 wide core. That is both more efficient than a10 and also probably aprox a quarter the size if not less. Different solution and performance profiles with different cost. Both Impressive in their own way.

Can this gb4 bm come a tad down. For years its was specfp/int. Now this.

Necro .. and none .. I have the s5 and it is the direct reason I dont want to own anything samsung again. To be fair it may well be as much android but the piece is p* me off on a daily basis that i wanna throw it into the wall.

probably exynos5422 had problems with overheating because he had to be set to 2.1Ghz and now it is 1.9Ghz.
exynos probably more firmly than the heats snapdragon.

The new Exynos 8895 has been revealed officially: http://www.samsung.com/semiconductor/minisite/Exynos/m/solution/mod_ap/8895/

I wonder what are the improvements of the new M2 cores over the previous generation ( and clocks ).

We can share some love for Exynos too, don't pamper just Ryzen
Rumours were 5-10% IPC improvements. Who knows about clocks, the aforementioned 2.5GHz might be true as they didn't really give a single figure about performance or frequencies.

New GPU is in line with previous Exynos'.

Surprising was the modem. It seems to be better than the S835's X16 besides the obvious lack of CDMA.

Also 4K 120fps recording is ridiculous. There won't be any device supporting this as the sensors will be the limiting factor.

I don't trust that leak because they got wrong the clocks for the SD835 and with my calculations the GPU on the Exynos 8895 is clocked at ~450MHz instead of 550MHz.
They have given huge steps in the modem department in a very short time. Living in Europe I couldn't care less about CDMA, I am more concerned about efficiency of the modem. And yep I was very surprised when I saw that 4K120fps.

Or the dispute started because they couldn't negotiate something upfront to begin with and relations broke down. Forcing Samsung to go to Qualcomm instead.

Hence why nvidia would try to block them both if they lost the opportunity. But Qualcomm having bought AMD's IPs weren't worried.
Or maybe NV wanted an access to Samsung fans.

I think this was the most importsnt feature as it shows power to eg handle 4k 60fps digital stabilization. Samsung is behind here.
In real world usage thats highly important. Hope it comes as a result of it. It would make 4k video usefull.

Besides that i am not sure those new small sensors is limiting in readout speed anyways? What makes you say that? Not that people need 4k 120fps..

Camera modules have their own ISP stacked under the sensor. 4k120 is 1.5GPixel/s and 18GB/s at 12bit depth. Besides the fact that that's some stupid processing power and bandwidth, it's also very power hungry and can overheat the module. The first 4k phones limited 4k recording because of module temperature.
