Anyone testing J4005 yet?
Today I have got a board and made some tests with Linux 64bit GCC.
The classic nsieve benchmark is fast or how do you interprete this:
Double as Jaguar at 2GHz and half of Core i7-8700 at 4.4 HHz
Open MP is like 90% on the second thread.
Any J5005 i have not seen yet.

i have only 32bit tests on J1900 and nsieve is close to Jaguar.

Time to revive this thread with the new Atom Roadmap!

image0.jpg

A new core every two years, Tremont in 2019, Gracemont in 2021 and “Next Mont” (month is a typo) in 2023.

Tremont is on 10nm, wonder if Gracemont shrinks to 7nm or if they will wait for the Next Mont for 7nm.

I think it's likely for Gracemont to be on 7nm, which makes more sense as TSMC is already working on 5nm and Intel needs to counter that.

Intel Pentium N5000/J5005 is between the Qualcomm Snapdragon 835 (Cortex-A73) and 845 (A75) in Geekbench 4 single-core (low-mid 2000s). Huawei Kirin 980 (A76) scores ~3360.

10nm Atom in 2019 huh. Hmmm, very interesting.

2021 for Gracemont on 7nm also seems likely. Gracemont may be used as a pipecleaner for the new EUV process. Might even be Jan 2021 if Intel is sufficiently aggressive. Anyone know when Tremont products will start hitting the market?

Forgot to mention something quite interesting notes under Gracemont

“Vector Perf”, I wonder if this means Atom will finally see some sort of AVX instruction set?

I’d say late 2019. Lakefield being one of those products.

Intel has done it before as a part of Phi. Kinda makes you wonder where they'll use Gracemont. Also I missed it, but the 'NEXT' Month is a funny typo there. Heh heh. Who proof-reads those slides?

Well well. It'll be interesting to see which makes it out first: Lakefield or IceLake U/Y.

Wasn't this the original plan before 14nm cause no new advancement for you are in foundry progression hell? Remind me but wasn't the goal to have a new atom core ever 2 years roughly?

Okay, here are the benchmarks! I've included my own Pentium J4205 (Apollo Lake) results where available and calculated the performance difference. Please note that the J4205 results are from Nov 2016 and used a different version of Windows as well as a much older graphics driver.

I observed the J5005 clock frequencies during an MT run of Cinebench R15. The CPU starts out at 2.7 GHz on all cores, but after ~1/3 of the test it settles down on alternating between 2.4 and 2.5 GHz.

It looks like the J5005 is 30-35% faster than the J4205 on average. I haven't done any extensive comparisons of operating frequency, but I'm guessing the J5005 runs at roughly 5% higher frequency. So average IPC improvement over Apollo Lake is probably in the 25-30% interval. Pretty impressive. Using Geekbench 4 for comparison, the J5005 seems remarkably close to the IPC of the Nehalem-based Core i5-760. Not spectacular performance for 2018, but I'd finally call the "Atom" pretty usable. This NUC, with a 256GB Crucial MX100, definitely doesn't feel slow. Single core performance appears to hover around 4 times that of the original Atom N270 (1.6 GHz) released in 2008.

After the table below, I've included URLs to some of the results (Geekbench/3DMark).

I spent an hour trying to get BOINC Manager to add the project, but it would always fail with a message along the lines of "Couldn't add the project. Please try again later". Yay... Tried two different BOINC versions and even attempted using boinccmd. Got a different error message there and decided to give up.
Hello! I admire your work a lot, may I know how I may send you a private message? Just some questions to ask about mini PC. Thanks!

Fresh Elkhart Lake code spotted with Gen 11 graphics. Most likely an potiental future Atom with a max of 32 EUs. The caviat of course is that assuming it is on Intel's 10 nm there's no guarantee a product using it will actually make it to market.
Going by the fact it’s using Gen11 and likely 10nm, it’s almost certainly using the Tremont core. I don’t expect to see Elkhart till 2020.

Lakemont is supposed to show up this year, isn't it? That has Tremont in it. If that can launch in 2019 then Elkhart Lake could very well ship at the same time.

I was actually going to suggest fabbing Elkhart Lake in some other node that's not Intel 10 nm. To me that seems like too much work for Atom but it'd be a waste to use 10 nm wafers on something so low margin when they are going to have to throw away a large percentage of the dies because of the yield.

That's the mystery behind it, at least to me. Are yields really going to be that bad? Intel is making Lakefield on 10nm. It's full-speed-ahead on that project. I see no reason why they wouldn't go ahead and keep updating Atom at every chance they got.

Elkhart SoCs should end up being smaller than Lakefield, but they’ll also be a lot cheaper, thus genenrally lower margin for Intel so I don’t think intel is going to prioritise Atom as 10nm first begins volume shipments. But hey, I could be wrong, maybe Intel will release what they can on 10nm ASAP.

The product that Lakefield is going to is going to be a low volume high margin device. Like Microsoft's version of the Galaxy Fold and/or the Courier. Intel is probably getting Coreish prices for the chip too.

Plus, Lakefield's 10 nm portion might just be the cores and the GPU, and nothing else. Elkhart Lake would most likely have to be a monolithic chip.

Hi !

I've bought a laptop with the N5000 (which I've not receive yet). And I would like to know if I made the right choice. Previously, I used a laptop with an i5-520um (ULV @ 1.07Ghz, overclocked by myself @ 1.6Ghz, boost @ 2.0Ghz).

According to benchmarks, the N5000 is more powerful, but it has less functionalities.
- pcie x16 for i5 vs x6 for N5000,
- turbo boost for i5, only speestep for N5000
- i5 with Flex & Fast Memory Acess, none for N5000 etc...

So, in use, these functions would make a difference ?

My second question is about the UHD Graphics 605. Obviously, this chip has the same power than the old Nvidia GT335m. Except for the Gpixel/s.

2.4Gpixel/s for the UHD 605 and 3.6Gpixel/s for the GT335m. This difference is really important or completely insignificant ? (the question behind, is : any game that I ran with GT335m will run with UHD605 ?)

Thanks

It might help people attempting to answer your question if you mentioned how you intend to use it.

Sorry, I forgot to mention my use case... So this laptop is for office, netflix and some old games (like Prey, Fear, or 1st far cry).
