Samsung’s Galaxy Alpha comes with Exynos 5430, the world’s first 20nm HKMG based chip

The Samsung Galaxy Alpha arrived with a splashing announcement yesterday, but there was one curious detail about the premium-looking metal-clad 4.7-inch smartphone that went a bit under the radar. Sure, we knew about the powerful Samsung Exynos 5430 octa-core chip roaring under the hood, but one interesting detail that has now slipped out was that this is in fact the world’s first 20nm high-k metal gate (HKMG) based chip on a smartphone.

This new, more precise 20nm process comes after for multiple years we had flagship phones running on chips made on 28nm lithography. The benefits of this new manufacturing node include the possibility to crank up clock speeds a bit, and achieve a better thermal footprint.

Samsung’s 20nm HKMG is a planar design, but the casting process now forms the gate as the last part of the transistor construction rather than the first, and this theoretically improves performance since gate characteristics are less affected by extreme temperatures in manufacturing.

We’re yet to learn more about Samsung’s 20nm process, but when it comes to the new Exynos 5430 system-on-a-chip, we do know that it is a big.LITTLE design using four Cortex A15 cores running at up to 1.8GHz, and four Cortex A7 cores running at up to 1.3GHz. Early benchmarks have shown it perform well, but we’ll reserve our final judgment for after we get the final Galaxy Alpha unit in our hands.

"Awesome!!! I cant wait to ditch my mi4 for this beast, mi4's $300 is overcheap and i hate it, not to mention 1080p screen, 3gb ram, 8mp front camera, 3080mah battery are way overkill and make me frustrating, while this beast costing $600 is attractive and i love it" -annoymous from parallel universe

More like an ignorant raging pathetic fanboy that spreads nonsense all over the place. For example, "GTFO! And sell your spyware somewhere else!". Gotcha beach!

Mediatek sweep exynos away

LOL I must be the #1 Exynos hater here on PA, But there's just no way those garbage mediatek chipsets can even come close to current Exynos crop.

Overpriced exynos can't even handle the heat properly

Are you a baby Do you have women's hands and fingers All electronic heats up when maxed out Do car and laptop and Pc users ever complain Do you love touching and feeling the part where the Cpu, Gpu is

LMAO, what? The weak, underpowered SoCs with weak GPUs sweep exynos away? Nice try troll.

I guess we can say that the 20nm compensates for the 1860mah of the Alpha...but by how much?

There's a Russian hands on video of it on YouTube and the device looks super fast and responsive. I would have considered buying it if it had a better screen, not that it's bad but with phones now sporting 400+ and 500+ PPI it's hard to overlook.

Im also a bit bummed by the screens brightness, 327 is not very bright...

But is it better than the Snapdragon 800?

It is, even 801 (checkhttp://www.gsmarena.com/samsung_galaxy_alpha-review-1114p3.php) With 20nm process, it is even more efficient. Remember Exynos 5430 is not the flagship SoC. 5433 with Mali T760 is, and to compete with S805 (supposed to be much better in term of CPU, GPU and even efficiency)

Samsung has been saying this ever since the very first big.Little architecture has been conceived, I wouldn't count on it though, SAMSUNG is all talk

If you have already formed this opinion then you shouldn't have asked. You should have just written "i think S800 is better than exynos 5430"... And btw the exynos chip in s5 is already better than s800.

Lol you think! big. LITTLE is a dog Deal with it

That's why Qualcomm is also using big.LITTLE in their next-gen SOCs (810/808) Moron go study about 8085 before you lecture others on big.LITTLE.
