Samsung announces 3nm MBCFET

Recommended Posts

Quote

 

Today’s announcement is that Samsung is offering its first alpha version of the PDK for its first generation 3nm process that uses MBCFETs. Samsung is calling this process its ‘3GAE’ process, and this alpha version will allow its partners to start getting to grips with some of the new design rules for its 3GAE process.

Samsung is making a lot of promises with its first 3GAE process. One of the headlines is lowering the operating voltage from 0.75 volts to 0.70 volts, which will be a good step in power. The headline PPA values that Samsung is announcing are also impressive: compared to 7nm, 3GAE will offer 1.35x performance, 0.5x power, with a 0.65x die area.

 

 

 

My thoughts:

While I think 3nm MBCFET is a ways off for consumer end, this announcement is a game changer, especially considering Intel's current position, their inability to hit 10nm, and considering their rival, AMD, is just starting on 7nm. Hopefully we'll see some collaboration between the 2 major CPU players in regards to this technology, which I think could bring it to the market even faster.

you realize it's a annoucement? it can one: still take years

 

and two: TSMC is already working on a more dence 7nm ("6nm) and already announced 5nm

 

it's still pretty cool tho

Yeah, I mean it's in the title.  But TSMC is using FinFet for their 5nm design.  It's nothing really new, just smaller FF.

Wonder what material they are going to use to prevent quantum tunneling which was the reason most people didn't think you could go smaller than 7nm.

 

sometimes i think people forget that Samsung is the largest Semiconductor manufacturer in the world since everyone gets caught up on TSMC and Intel, though that might be because their focus isn't on Microprocessors. would love to see Samsung join the race for CPUs though

That's all they do now, but they are the largest semiconductor manufacturing in the world. I'd love to see a collab between them and Intel / AMD. It would benefit both companies. I could at least see them licensing MBCFET, as it seems to be a better way forward over FF.

Samsung is a lot of things; one of them is a foundry. They can make anything you want as long as you pay.

 

If you want examples they've made some Nvidia GPUs. I also think IBM will use them for some upcoming high performance CPUs or so I've heard.

as long as they don't sell off the fabs that matter to progressing down that path ._.

also they have a contract with AMD to get them to utilise their fabs up to 12nm (they've got quotas. yeah), so oof for AMD

CPU's are by far the most important product from fabs, x86 and ARM, they have only produced mobile optimized ARM's, when high clocks and high performance/density is the problem their technology maybe wont be that good. They did produce GPU's for nvidia but GPU's are not CPU's, they run at much lower clocks, and yields while still important its not as damaging since GPU have many units that can be disabled if faulty, CPU's not so much.

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

what has nodes really done for consumers since 32 nm besides lower the cost or energy at times?

It has doubled the core count in 95w parts, boosted stock frequencies by over a GHz on similar architectures and decreased power draw on laptops allowing for thinner and lighter products. Seems good to me.

core count has always been around just premium-ed til amd started core wars 2 which they are winning this time

remember 22nm had stock of 4ghz on dc and 4.4 on boost

and sandy bridge 32nm was quite easy to get 4.5 using STOCK cooler acted like 7700k

This is interesting, I like the vertical scaling, not sure how that works in lithography. I want to see more on this. I like the idea of converting existing FinFET designs to MBCFET and seeing what kind of changes to power and performance will be seen.

I don't think it will be much longer. I'm interested to see what's the plan is. It could be stacking, but I doubt we're getting much smaller than 3nm. I'd imagine there is work being done regarding graphene and molybdenite as a way forward. Or at least I hope there is.

You're not listening - it has doubled the core count on 95w parts. Without compromising the singe core performance. FX cpu modules were hardly the same thing as two zen cores. Also, AMD will launch a 64 core part soon - we never got anything close to that. Intel has been crawling up to 28 cores at a painfully slow 2 cores at a time, at ludicrous production costs, because they 1) couldn't shrink their process and 2) don't have a modular design like AMD. AMD on the other hand went straight for 32 cores and is doubling that thanks to their upcoming die shrink.

This would not be possible without 7nm tech - you can clearly see how those 8 chips wouldn't fit if they were twice the size.

95w sandy was 4 cores max - and no, you couldn't get 4.5 on the stock cooler without overheating. I have one, the stock cooler is barely enough to keep it from overheating at stock speeds. Also just because Intel didn't use the lower process nodes to make a better cpu doesn't mean the potential wasn't there, and AMD came in and used it forcing Intel to step up their game.

 

Node shrinks are literally the main reason we have advancements in CPU technology at all. There's only so much you can tweak to get better performance and only so many cores you can fit on a die - unless you shrink the whole thing.

well global foundries is specializing on different nodes that others dont offer, a good example of this is their new 12nm planar node which seems great promising power and cost savings

temps were at 75-80 on stock

2600k hit 4.9 with mid sixties on d14

 

fyi I had few sandy bridge cpus it was easy

and there is many articles/threads/reviews/etc on them hitting 5ghz too

 

yes i know node shrinks help but how to the consumer? really how? they get more and consumers get same price pretty much even with new nodes

maybe few hundred mhz if that

cores would be same thing if amd didnt start this core wars 2

 

tweaks to isa get advancements too plus many others

The node shrinks were pretty important on the mobile side too. 32nm peaked with the Apple A5X used in the iPad 3, which was hot, quite power hungry and was just barely enough performance to drive the display. 28nm or lower was really necessary here.
