A question. Cherry Trail tablets is expect to this year?

Cherry is braswell 64?

Cherry is BayTrail-T
Braswell is BayTrail-D

I think...

A question. Cherry Trail tablets is expect to this year?

Cherry is braswell 64?

According to Fudzilla Braswell is the successor to Bay Trail-D and Bay Trail-M while Cherry Trail-T is the successor to Bay Trail-T. I wonder what are the differences if that's true.

Bay Trail reinvented the Atom line-up, which was neglected by Intel for years. It also brought Windows 8.1 to new form factors, namely compact and affordable tablets. The company has now announced Braswell, the 14nm successor to Bay Trail-M and Bay Trail-D parts. Cherry Trail will replace Bay Trail in the tablet space.

It's not going to be 20-30% on the CPU side unless it's an incredibly memory centric measurement. It will be a substantial gain on the power side however. The GPU side is going to be easily more than 50% in most scenarios

We don't know if there are some enhancements in Armont over Silvermont beside the frequency increase. The GPU is more likely a 2x improvement.

Maybe is same design only with lower tdp/perf? 10w(low factor pc, ultrabooks etc) vs 2w (tablets/smartphones)?

Indeed. Might be the case that Intel realized the confusion that having variants - Baytrail-T, Baytrail-M, Baytrail-D and such - creates and instead decided to give them different code names more appropriate to the target markets? The 'wells' are for desktops/laptops while the 'trails' are for tablets and the 'fields' are for phones... at least for the moment.

So, Braswell is Broadwell-Y?

BT-T while offering a smaller package, it did still have inside all the SATA, pci-e controllers inside... i think if they do this, its because Cherry Trail is not having any of that.

 

[mikk]

Braswell is Atom based, so most likely a renamed Cherry View.

Quick sync and eMMC on starting on Spring refresh '14 Bay Trail-M. Nice....although I thought eMMC was already enabled on Bay Trail-M looking at the ECS Liva Mini-PC--> http://forums.anandtech.com/showpost.php?p=36207287&postcount=2338 and seen much earlier here---> http://www.tomshardware.com/news/ecs-v20-mini-lake-bat-i-v20,25679.html

^^^^^ Notice N2805 (Bay Trail-M) listed together with 32GB eMMC in that above picture.

Regarding Braswell, I wonder if it doesn't end up being a die chop variant of Cherry Trail that has less EUs for the iGPU.

In other words, Intel takes Cherry Trail (14nm airmont atom) and makes a new die with something like 6 or 8 EUs. Maybe even make it dual core?

It might have fewer EUs than Cherry Trail due to less competitive pressure in the laptop market, but it can't just be a fused version of the tablet chip as it will need support for SATA/PCI-Express which is totally useless due to power/cost constraints in a tablet.

I was thinking there would also be a Cherry Trail-M and Cherry Trail-D (Just like we see with Bay Trail)

......then this new Braswell would simply be a new die derived from Cherry Trail via chopping out certain sections at the design stage and then rearranging to make the new SOC before it hits the fabs for production:

Example of "chopping out sections at the design stage to create a new die derivative" from this RWT article using Sandy Bridge; http://www.realworldtech.com/sandy-bridge-circuits/

Braswell is Cherry View not Cherry Trail. So it's a different Die regardless of what Cherry Trail offers. Here is a schematic: http://chinese.vr-zone.com/107448/aim-for-chromebooks-intel-outs-braswell-soc-04042014/

There is PCI Express and Sata functionality which Cherry Trail-T doesn't offer.

Then its exatly the same thing as BT but with a name change....

btw, what is SVID? s-video?

No it isn't. Bay Trail and Cherry View/Braswell are two different products.

 

[bullzz]

why would there be 2 products if they are the same i.e braswell and cherry trail.
i think braswell is a cut down haswell or broadwell

 

[cbn]

According to the schematic mikk provided in post #2415, it is atom (specifically quad core atom). We also know it will be built on 14nm.

My question is how many EUs will it have? 16 EUs.....or less than 16 EUs?

If less than 16 EUs, will these be die hardvested from that parts than originally had 16 Eus or will Braswell have it own specific die than contains less than 16 EUs?

Who told there are two products? It's a simple Cherry View renaming, most likely for a more suited product segmentation. -trail for tablet products, -field for smartphones and -well for desktop and notebooks.

Kirk Skaugen told at IDF it is Atom based by the way.

To me that implies Braswell would have 16 EUs.

If so, that is rather disappointing

I was hoping this "low cost chip" (Braswell) would truly be a low cost chip from the ground up. (ie, small die size, fast airmont dual core, modest iGPU and the appropriate SATA/PCI-E for laptop and economy mini-desktop)

They should just fire their entire marketing department, because a six year old would have done better without conjuring painful experiences with 2008 era netbooks in consumers.

I'm serious.

Cut the hyperbole. Core-based chips do offer much better performance per-core but comparing Bay Trail to 2008-era netbooks is just stupid, Bay Trail is noticeably faster than older Atoms. There's a market for both 10W soldered Bay Trail-D and 54W LGA Haswell Celerons, its not like they're replacing one with other. I do agree that Intel's current branding is a bit confusing though.

16EU its more than Broadwell GT1, i bet Braswell ones will be using higher igp and mem frecuency, thats all they need.

Why it is disappointing? Haswell GT1 has 10 EUs. 16 EUs would be pretty high for this SoC. We don't have a confimation for EU count on Cherry View/Braswell.
