    Looks like it scales up to 24 cores/2.2ghz/27mb “cache” although it’s not clear how that cache total is organized: https://www.intel.com/content/www/us/en/products/p...

    Thanks for the link. Thats quite impressive for atom. And it is getting very wide compared to first atoms. 6-wide OoO is Sandy Bridge territory and most likely higher IPC thanks to newer instruction set. This will most likely be directly comparable to 12-16 big cores (where it can get most of parallelism).

    It has 2 sets of 3-wide decoders. In straight-line code it can only decode 3 instructions per cycle. For branchy code the 2nd decoder reduces latency and helps filling unused decode slots, but that doesn't make it 6-wide. It has 4-wide rename so even if the decoder could produce 6 instructions, it could process only 4.

    It's definitely the fastest Atom so far, but like all its predecessors, it remains lacklustre. At just 2.2 GHz (no turbo!), no AVX, no SMT, it would take ~3 of these to match 1 big core...

    I agree. Hence the choice of 4 Tremont cores and one sunny cove core in Lakefield.

    Not needed if you are ok with the 2GHz it offers. It's faster than a Raspberry Pi 4b per core, and it has up to 24 of them instead of 4.
    For Boinc, FAH, or other data crunching, the 24 core could probably outdo a 9th gen Core i5 (4/8 CPU/threads) in all core load.

    Thanks for the link. I am curious about two thing

    1. Is this basically tremont processor
    2. is this serious e basically the successful for C series chips like the C3955

    Never mind - article states it - but it does state it.
  • DanNeely - Monday, February 24, 2020 - link

    Those numbers imply 1MB + 128kB/core; although partitioning into 3 levels is certainly possible. Do we know anything about Tremont in general?
  • Wilco1 - Monday, February 24, 2020 - link

    Yes, according to https://www.anandtech.com/show/15009/intels-new-at... 27MB for 24 cores looks like 6 4-core modules with a shared 4.5MB L2 cache. So no L3.

    Interesting wrinkle here though: https://www.intel.com/content/www/us/en/products/p...

    "L2 Cache of 4.5MB per 4-core cluster and shared LLC cache up to 15MB"

    The L2 matches up, but this supposed shared LLC doesn't seem to show up anywhere.

    It's designed to be faster? You don't say.

    It reminds me of that time when Intel made Atom chips for phones but only released them in China because they could throw people in jail if they complained about how phones with "Intel Inside" are unbearably bad.

    After a decade of junk hardware (e.g. the netbook that takes 20 minutes to boot Windows, that has a 50 ms latency to the Wifi, ...) it seems Intel is positioning the "Atom" brand to places that are invisible to the consumers and when "performance sux" everybody can point the finger at somebody else. Put Atom in a 5G base station and latency will be worse than 2G. Can't get a signal even though the coverage maps say you should? Obviously you can blame the people who would open a Sprint store in my town, get 95% of the phones returned because Sprint doesn't work in this area (except for the 5% that is most built up), close it down, then wonder why they don't have a store in my town, and repeat...

    Their 16 and 24 cores are extremely interesting for singleboard computers!
    I was hoping they would release these CPUs for mobile and small singleboard computers, for hobbyists!
    Those 24 cores could compete with Ryzen 3000 series CPUs, if the single board computers would accept a single 12V input, and limit to 30W TDP.

    Thanks for the article, it would be great if there were such articles everywhere: https://radiofrench.fr/ecouter/rtl.html
