    I want 5Ghz as my 9900k
  • hary232 - Monday, May 11, 2020 - link

    +1
  • close - Monday, May 11, 2020 - link

    I guess then it would cost $500 and be slower than the competition.
  • Deicidium369 - Monday, May 11, 2020 - link

    What competition? The cheap Chinese knockoffs AMD?
  • Thud2 - Monday, May 11, 2020 - link

    Wow. Biased, Delusional and out of touch much?
  • kobblestown - Monday, May 11, 2020 - link

    Well, it supports 5G, doesn't it?! ;)
  • Wilco1 - Monday, May 11, 2020 - link

    You don't need anywhere near 5GHz to beat a 9900K. Eg. A13 has the same performance at 2.6Ghz, almost half the frequency!

    The same microarchitecture as Cortex-A76 is used in Graviton 2 and Ampere Altra which beat ridiculously expensive Xeon chips by a huge margin, all without needing 5GHz and while using far less power.

    5GHz = huge, expensive, power hungry chips which are easily beaten by smarter designs. Stupity, all driven by marketing rather than good engineering.

    This is a popular misconception that needs to die.
  • Kangal - Monday, May 11, 2020 - link

    Which part?
    The old AMD Bulldozer parts clock insanely high, yet they get outpaced by simple Core i3's and probably some ARM SoC's too.

    Frequency is important, but so is IPC, and so is efficiency, and so are drivers/software, etc etc....

    Every part? Coffee lake has a 19 stage pipeline, 22 execution units (up to 4 per operation type), and 1 MB of L3 per core.

    A76 has a 13 stage pipeline, 8 execution units, and 1 MB per core. Where is the supposed magic gain in IPC?

    A shorter pipeline is better for IPC. Most Arm designs have 64KB L1 caches and L2 at 512KB or 1MB, so 2-4 times as large as Skylake.

    Also Skylake can execute up to 4 instructions per cycle (plus 1 with branch fusion) and has 8 execution pipelines. Cortex-A76 does also 4 instructions per cycle and has 8 execution pipelines.
  • jospoortvliet - Monday, May 11, 2020 - link

    Note that a shorter pipeline means better performance (but lower clocks), all other things being equal (which they are not, of course!).

    But you are right that it is near impossible to imagine those 22 execution units not kicking the a** of the A76. But keep in mind that Skylake can only shoot 8 ops into these units per clock, that is beaten by Apple's a12 at 9, and yes, equaled by the A76 with 8. Im no cpu designer but it seems to ignorant me that if the execution units are fully pipelined it doesn't matter if you say there are 20, but you can feed only 8 per clock. Given all the other differences they are probably hard to compare but given they can pump a similar nr of instructions in the execution units i would guess they aren't THAT far off in IPC... not 22 vs 8, at least.

    We do know Apple with its 9 is far (30-40%?) ahead of the A76 so the 8 vs 9 doesn't say everything - it isn't 40% more...

    But I agree Intel is probably still ahead of the A76 in IPC, apple might have surpassed them, maybe the A76 is close but it sure isn't 40% ahead of intel which it would need to compensate for lower frequency..
  • Wilco1 - Monday, May 11, 2020 - link

    You're quite right it's all about feeding execution units. But let's compare using actual measured SPEC results rather than meaningless execution unit numbers.

    According to AnandTech's SPECINT results, Cortex-A76 has ~12% higher IPC than the 9900K - see https://images.anandtech.com/doci/15776/SPEC-D1000...

    Similarly Neoverse N1 (which uses the same microarchitecture as Cortex-A76) has ~16% higher IPC than Cascade Lake, see https://images.anandtech.com/graphs/graph15578/111... from the Graviton 2 review: "It’s a great showcase of the Neoverse N1’s IPC capabilities, as the cores are only running at 2.5GHz compared to ~2.9GHz for the AMD system and ~3.2GHz for the Intel system."

    The latter result is more accurate since memory systems, cache sizes and frequencies are very similar for these servers, unlike any mobile vs desktop comparison.

    The A13 has not just surpassed Intel and AMD in IPC, it has 1.8 times the IPC! The reason it can execute twice as many instructions per cycle as A76 or Skylake.

    So I repeat, aiming for 5+GHz is as stupid as Pentium 4 or Bulldozer was.
  • KarlKastor - Tuesday, May 12, 2020 - link

    Where do you see there a higher IPC for the A76?
  • Wilco1 - Tuesday, May 12, 2020 - link

    It's basic math:

    Neoverse N1 scores 32.34 / 2.5GHz = 12.9 SPECINT/GHz
    Platinum 8529 scores 35.74 / 3.2GHz = 11.2 SPECINT/GHz

    Excuse me, the P4 was NOT stupid. You talk about parallel processing, blah blah blah but what other CPU would allow you to fry an egg whilst SIMULTANEOUSLY weeping at the shoddy performance? We called it Simultaneous Multi Egging. It was ahead of it's time and AMD have clearly just ripped off the nomenclature.

    Okay, fine. I'll be quiet and go away.

    Amen

    I think i found the AMD stockholder. Was wondering when you’d pop up. How the f*ck can you be so retarded as to compare an ARM cpu against a fully fledged desktop cpu and even go as far as to claim that it “beats it”? Can the A13 execute x86 instruction sets? Do you think that, if it were that good, Apple wouldn’t use them in their line of Macs and iPads and instead, choose to pay Intel for their CPUs? God damn it, the internet’s wikipedia has turned all you dropouts into PhDs.
  • Wilco1 - Monday, May 11, 2020 - link

    LOL - A13 actually beats the 4.7GHz Ryzen 3950X on SPECINT: https://images.anandtech.com/doci/15776/SPEC-D1000...

    You'd have to be retarded to believe that the next generation will not beat the fastest Intel and AMD desktop CPUs. And: https://www.bloomberg.com/news/articles/2020-04-23...
  • MarcGP - Monday, May 11, 2020 - link

    Hold your horses, no need for name calling. He was talking about the Graviton 2 and the Ampere ARM server processors, not the Apple A13. They were reviewed and benchmarked by Anandtech and they did a pretty good job keeping up and even besting the top x86 server processors.

    https://www.anandtech.com/show/15578/cloud-clash-a...

    By the way, everybody seems to agree that this time is going to happen, that the next generation of Macbooks will use their own Apple ARM SOCs.

    And an heat shield to use it

    I’m making more than $75k by just doing very easy and simple online job from home.Last month my friend sister received $94280 from this work by just giving only 2 to 3 hrs a day.Everybody start earning money online. visit for more details… www.iⅭ­a­s­h­68­.Ⅽ­O­Ⅿ

    The first AP SoC supporting Bluetooth 5.2!
  • QhyQhy - Monday, May 11, 2020 - link

    where does we find official info about this alleged BT 5.2 ?
  • Vince789 - Monday, May 11, 2020 - link

    See Qualcomm's 768G product page
    https://www.qualcomm.com/products/snapdragon-768g-...
  • anro15 - Monday, May 11, 2020 - link

    I'm seeing in 'other' publications (sorry!), that the 768 also supports updatable graphics drivers for the 620. Any further info on this?
  • Spunjji - Monday, May 11, 2020 - link

    I really wish they'd stop it with this endless fragmentation.

    Snapdragon used to *mean* something, back in the earlier days of smartphone SoCs. Now I have to cross-compare across a spreadsheet to figure out whether this is actually better than last year's mid-range with a higher number and lower performance, or the high-end from the year before.
  • flyingpants265 - Monday, May 11, 2020 - link

    It's actually pretty simple:

    Snapdragon 800 = laggy, everything else = laggier

    A76 in 2020 = pass.
  • Wilco1 - Tuesday, May 12, 2020 - link

    Despite it having a higher IPC than your desktop PC?
  • s.yu - Monday, May 11, 2020 - link

    I wonder whether it's that Samsung now has improved yields on the 7LPP or that Qualcomm's been hoarding all these better bins since 765's release all along.
  • eastcoast_pete - Monday, May 11, 2020 - link

    Thanks Andrei! Question: How much efficiency does the Samsung 7 nm EUV LPP gain vs the 8 nm LPP?
