Intel Announces 12th Gen Core Alder Lake: 22 New Desktop-S CPUs, 8 New Laptop-H CPUs (anandtech.com) 35

When Intel launched its 12th Generation Core family of processors late last year, it was only a small set of overclockable parts for desktops that came to market. Featuring Intel's new hybrid core design, the hardware proved competitive and cost effective, making it a very interesting time to be a consumer. However, the main battle for volume sales is typically in the mid-range and notebook segments which power millions of devices, and Intel is launching these processors today. From a report: These include the 35 W and 65 W desktop processors, new desktop coolers, and a handful of 45W+ laptop offerings for the creator and gaming markets. While all the glitz and the glamour goes to the high-profile overclockable processors in any given generation, the bulk of Intel's sales actually comes from the standard, run-of-the-mill hardware that gets put into the majority of commercial and pre-built hardware. To that end, Intel usually releases anywhere from 10 to 50+ new desktop processors to fill in the markets where needed. These processors usually come from anything up to four base physical designs, and parts of those chips are disabled depending on yield or market demand and sold accordingly.

For Alder Lake, Intel is launching 22 new desktop processors, from $42 dual core Celerons at 35W all the way up to $489 Core i9-12900 parts. Split down, here's what all the Core names mean:
Core i9: 8 Performance Cores + 8 Efficiency Cores
Core i7: 8 Performance Cores + 4 Efficiency Cores
Core i5: Either 6P+4E, or 6P only
Core i3: 4 Performance Cores only
Pentium: 2 Performance Cores only
Celeron: 2 Performance Cores only

Just putting Core i5 aside for a split second, what we have here is a scale of hardware that changes in performance cores, but only a select few have efficiency cores. This is because Intel is using two base physical designs for this hardware: either a large 8P+8E chip or a smaller 6P only chip. The smaller chip makes the economics of the lower core count processors work out better, but it does mean that one of the key features for Alder Lake, the hybrid CPU, will be limited to the high-end hardware only.

    The whole power vs efficiency cores. It vaguely reminds me of the Optimus setup that was popular on laptops at one point. Nvidia for horse power and the Intel for when you didn't need it. Honestly, the one laptop I had that on, I forced it to always use Nvidia. For what I do it worked better. Not sure if this will be similar at all, but I'm not sure I personally need or care about the 'hybrid' idea. I'll try and keep an open mind, but I do have some lingering doubts about how ultimately useful it will be.

      As many things, it depends.
      For one, the cores are all on the same CPU die, meaning that they're a lot more integrated than if you try to split loads between discrete GPU and integrated graphics, which should make things easier for a scheduler to handle. But ultimately what you observed can still hold true, that you just don't need the efficiency cores, because the performance cores are already enough to handle everything sufficiently.

      However what I suspect is that these high core trends may also lead to
    • It also needs to be retitled "Intel announces their usual confusing muddle of one product in two dozen almost-indistinguishable variants that exist only to hit artificial price points".
    • What I remember about Optimus was the horrible pain it was go switch GPUs under Linux. I was reading elsewhere (sorry can't remember where) that P and E core usage on Linux is not sorted yet- a little ominous, but I suspect this will be handled soon with new kernels.
  • If, like me, you had no idea about what an "efficiency" core is, there is some information here [pcmag.com]

    • Yea, what's in a name?
    • I build Linux based DAWs (digital audio workstations) and this is interesting. On Skylake processors the advice is to disable hypertheading (or get a single threaded CPU - the i5 range features these) and disable Turbo or Boost mode (I forget what they called it). These new CPUs seem to invert the paradigm where "Turbo Mode" is the default and background tasks are handed to the Efficiency Cores. I don't like the idea of multithreading and now they throw different clock speeds into the mix. Digital audio nee

        Depending to processor model and generation, there are two or three turbo modes each with its own name.

    Tom's got a very early review: https://www.tomshardware.com/n... [tomshardware.com]

    tl;dr: It's great value at $185, almost as fast as the 12600 in games and about 20% slower in rendering etc. Also faster than comparable Ryzen CPUs.

      That isn't being entirely genuine. That is the case with their "FPS" and "Gaming" (1080p and 1440p, no 4k tests for some reason) benchmarks, but go down to the iGPU benchmarks especially, but also both the Single Threaded and Multi Threaded CPU Performance benchmarks, and you see Ryzen keeping its own or beating Intel, especially the Multi threaded

      • That isn't being entirely genuine.

        Er...not exactly. Keep reading their analysis in the first article you referenced. Seems to me the fuller picture is that the 12400 on the whole meets or beats the Ryzen offerings, except for one of the benchmarks. So it seems the Intel wins much more than the Ryzen, even on non-gaming benchmarks. But, the thing that I don't see anyone pointing out here, is power consumption to get there. Intel TDP != AMD TDP. On average AMD TDP is really a max power measure, and Intel's is less so. In fact, Intel h

  • Manufacturers can't even get their machines out the door because private industry screwed up the supply chain. I have orders from last April which still aren't filled. I'm supposed to care about new chips?

  • ...until at least 14th generation.
  • FFS, they are still selling 14nm devices. My toaster will have a 4nm CPU before Intel does.

  • Seriously. They have not had a good CPU in a long time.

  • 115 watts peak, just for the processor. btw: power consumption increases linearly with the square of the frequency. You might be impressed to hear 5.5 GHz, but that's really not something to be proud of.

    Have they worked out all the security bugs in the architecture? Seriously, is Spectre and it's zillion variants finally dead? Did Intel fix the SGX flaws? Are the synchronous transfer instructions still flawed?

    Intel really needs to address a bunch of design flaws if they haven't. On top of that, has Intel stopped lying about it's benchmarks? How about the anti-competitive behavior? Intel has a lot of things to work on and until they do, I'm not buying shit from them.

    • Mod up. The right for non-defective processors. Clearing memory and cache, preventing 'dirty' scavenging, costs performance. Doing this on slow 14nm Vs 5nm means AMD are all over them till they shrink. If they cant compete on speed, how about adding keyed memory like IBM and ZOS - for decent security and that will also break poorly written programs. Never-mind Apple is doing their own thing now, while AMD is refining finished product. You may not remember original Pentium III processors with the daughter-b
      • They have encrypted memory - one encryption key for privileged OS code (OS/supervisor) and a single different one for client code.
        As for the cartridge Pentium !!!, AMD had that too in the early K7 platform (and looked much better too).

      • You may not remember original Pentium III processors with the daughter-board upright with a bigger fan attached.

        You may not remember original Athlon processors which were sold in the same sort of form factor (and with the same connector [wikipedia.org]! but with different signaling.)

  • i have to buy 15 new machines so i guess i'll go with one of these cpus.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
