When a processor is manufactured, it has a series of designations to identify it, such as the name. But alongside this, as with almost every manufactured product ever, each product will go through a number of revisions and design reinventions to do the same thing better or add new functionality. For microprocessors, aside from the model and family name, we also get what are called a ‘Revision’ and a ‘Stepping’ for each model, with the stepping being used for enhancements that increase the efficiency or add features. New steppings require a complete revalidation process for yields and back-end work, but for example a typical Intel mainstream processor will go through three or four steppings starting with the first silicon.

What Intel has published in the last couple of weeks through a 'product change notification' is an update to the Atom line of desktop-embedded processors that use Cherry Trail cores. The combination of cores and marketing position gives this platform the name Braswell. The Braswell update is a new stepping which adjusts the power consumption of the cores, raising the frequency, raising the TDP of the Pentium variants for a larger product separation, and renaming both the processor itself and the HD Graphics implementation. This change is referred to in the documentation as moving from the C-stepping to the D-stepping, which typically co-incides with a change in the way these processors are made (adjusted metal layer arrangement or lithography mask update).

Intel Braswell SKUs
SKU Cores /
Graphics TDP Price
Celeron N3000 2 / 2 1040 2080 1 MB HD 4 W $107
Celeron N3050 2 / 2 1600 2160 1 MB HD 6 W $107
*Celeron J3060 2 / 2 1600 2480 1 MB HD 400 6 W ?
Celeron N3150 4 / 4 1600 2080 2 MB HD 6 W $107
*Celeron J3160 4 / 4 1600 2240 2 MB HD 400 6 W ?
Pentium N3700 4 / 4 1600 2400 2 MB HD 6 W $161
*Pentium J3710 4 / 4 1600 2640 2 MB HD 405 6.5 W ?

* New parts

The new SKUs will still be Braswell parts, with the names changed from N to J with the number adding 10.  The Pentium models will go from 6W to 6.5W, have an increase in burst frequency, but at this point the exact value has not been published. Edit: Thanks to @jacky0011 who pointed out that the Intel Download Center auto-complete function has the turbo mode for these listed. Pentium models with 16 execution units in their integrated graphics will have their graphics model changed to Intel HD Graphics 405, while Celeron models with 12 execution units are now Intel HD Graphics 400. In both cases, these are accompanied by new drivers as well. For system designers, it is worth noting that the ICCmax value for the new stepping rises from 7.7A on the old to 10A on the new for the CPU, and from 11A to 12A for the graphics, meaning that the new chips can be plugged into original Braswell designs but only if they meet the new ICCmax criteria.

Intel expects minimal validation for customers wishing to use these new parts, but they will have new S-Spec and product codes requiring a change in ordering. Intel’s timeline puts the first samples for customers are available now, with qualification data at the end of November. Bulk shipments of chips for devices will start from January 15th 2016, with all shipments finishing on September 30th 2016. Chances are we'll see the current Braswell crop of devices (mini-PCs, NAS) with the newer parts, depending on availability and current stock levels.

    A little like the way the expensive G1 ssd never got TRIM support but the soon after released G2 model did.

    I've got a silent HTPC system too (using a slightly older J1900). These look like they have some enhanced graphics options, a smaller lithography and likewise a lower TDP, but are probably pretty similar overall.

    It's funny, I too have a silent PC. It has a Core i7-2600K in a cramped itx box. The only two fans are - one in the power supply, and the other 160mm or 200mm (don't remember exact size) installed on front of the case. I was hearing the 5400rpm HDD spin so switched to SSD. No more noise from my rig, granted that I'm not doing anything serious with it these days. The desktop use around 25W on idle.

    But it would be cool to have a very slim and tiny desktop with these chips completely passive cooking.

    It's nice to see Intel is continuing to put work into making more practical processors that fit into peoples' lives better than those huge, hungry Core iX chips in impractical, immovable desktop computers. Some of the most usable computers out there without stupid fans and high cost are using Bay and Cherry Trail processors. I would like to see more of them start to ship with 4GB of RAM in dual channel though. Most of the more cost effective computers are still on a single memory channel with only 2GB even though the processor is capable of doing more. I would really love to see a Stream 11 with dual channel memory and maybe 64GB of storage. It'd make the perfect little computer once you reload it with Linux to get rid of all the Windows 10 telemetry that has a lot of people losing their minds these days about Microsoft spying.

    Even the big cores are actually pretty tiny today. Even at 6 W TDP I'd rather have 2 Skylake cores than 4 Braswell cores for general office work. Comparable multi-threaded performance and vastly superior single threaded performance. The production cost is not all that different, it's just Intel charging more for the powerful chips because they know these are worth a lot more for many people and applications.

    That is the point. They weren't including support for 4GB RAM for segmentation. Otherwise, we will be fine with these Atoms with 4GB RAM. I can't forget that Asus T100 with 2GB RAM.

    Pentium N3700 for $161? Huh?
  • djsvetljo - Tuesday, March 15, 2016 - link

    It's now March and I can't find a single motherboard with these CPUs embedded. Anandtech, do you have any inside
