  • All of AMD's desktop plans for 2019 may have just leaked.  (WCCFTech)

    Yes, WCCFTech, but also at Reddit and AdoredTV, so two independent sources that agree on most of the details.  And none of it is prima facie implausible.

    Summary of the leaked CPUs:

     Part  Cores  Clock  TDP  Price
     3300  6  3.2 / 4.0  50W
     $99
     3300X  6  3.5 / 4.3  65W  $129
     3300G  6 + 15 CU  3.0 / 3.8  65W  $129
     3600  8  3.6 / 4.4  65W  $179
     3600X  8  4.0 / 4.8  95W  $229
     3600G  8 + 20 CU  3.2 / 4.0  95W  $199
     3700  12  3.8 / 4.6  95W  $299
     3700X  12  4.2 / 5.0  105W  $329
     3800X  16  3.9 / 4.7  125W  $449
     3850X  16  4.3 / 5.1  135W  $499

    All the parts have SMT, so 6 cores means 12 threads, and so on.  The G series parts are APUs with built-in graphics, so the 3300G has 6 CPU cores + 15 GPU cores (called CU, for compute units).  The current 2400G has 4 CPU cores and 11 CU, and the Radeon 560 card has 16 CU, so that's a significant upgrade.

    The low-end 6 and 8 core parts (low-end!) have one of the new CPU chiplets. The APU parts have a CPU chiplet and a GPU chiplet, and the high-end parts have two CPU chiplets.  The new design lets AMD mix and match without having to design and test new dies.

    The CPUs are expected to be announced at CES in January (where AMD CEO Lisa Su has the keynote), except the 3850X which is believed to be a special 50th Anniversary limited edition and will arrive in May.  The APUs will be along in the second half of next year.

    The 3800X and 3850X may need updated motherboards as they exceed the power specs for the AM4 socket.  There will be a new X570 chipset as well.

    There are new graphics cards coming as well, but information on those is scant.  If you want all the details, watch this video.



  • Nvidia's Titan RTX is a bigger and more expensive RTX 2080 Ti.  (AnandTech)

    Not a lot faster except for the AI performance which is clearly artificially limited on the consumer graphics cards.  But double the memory - 24GB vs 11GB - which could be a big win for heavy processing tasks.

  • Razer has updated the Razer Blade Stealth with crappy dedicated graphics to replace the crappy integrated graphics.  (AnandTech)

    Really, it's intended to use an external GPU over Thunderbolt.  The Nvidia MX150 just makes it suck a little less when being used on the go.

  • Qualcomm announced the Snapdragon 855.  (Fudzilla)

    Details: It's designed by Qualcomm and is called the Snapdragon 855.  Yeah, not much of an announcement really.

That's the complete run so far, in two convenient bundles.  The second bundle runs a little over an hour, so get some snacks, maybe a drink.

1 I can't remember where I saw it but earlier I saw claims the 855 will have 8 cores:  one at something like 2.8 or 2.9GHZ and 3 more around 2.4GHz; those will all be A76s, and then it'll have 4 slower cores (A53 or A55, I forget which).  Don't remember if that was presented as a leak or "this is what it's going to have".  I guess it'll be interesting to see if it matches reality.
Can't wait to see what the 3000-series Ryzens look like.  Those turbo numbers look like either serious Intel-style binning for segmentation, or that the yield of the best cores won't be great.  I'm still using a 1600X, but on an Asus X470, so no PB2, instead I manually set up a bunch of P-states, something like 3900, 3500, 2200.  Am thinking of tweaking it a bit more; I'm pretty sure the chip can handle 4000, and maybe a hair more, and I'd probably also like to add a few more low-power states.
Rzyzen 1 doesn't shed heat nearly as fast as Intel chips do when clocking down, and I don't think it likes to clock as low at idle, either, but I kind of want to explore the limits of that.

2 One of the things the video goes into is that the new chiplet design makes it much easier for AMD to do crazy part binning.  They don't need a perfect 16 core chip, they just need two perfect 8 core chiplets.  Since the 8 core chiplets are half the size, you get about four times as many in the top bin.

3 The way those clock speeds are all over the place makes me wonder if there are yield issues that result in chiplets that aren't capable of clocking up very high, although it could just be Intel-style artificial product segmentation.  Also, I wish some of the lower products on the stack could clock up as high as the higher-end ones.  With the 1000- and 2000-series, even the low-end chips could XFR up nearly as fast as the high-end ones (although in my experience, seeing my 1600X boost to 4.1 at stock clocks was pretty rare; it tended to just peg all 6 cores to the base XFR speed of 3.7.  My guess is limiting the boost to 2 cores was too conservative and that the thing spent too much time with too many cores active to get the boost.)
Nonetheless, if the 3000 series is anything like these numbers I'll probably upgrade.

4 The clock speeds actually have a steady progression as the price increases - except for the two G series models.  That's almost certainly because the GPU chiplet is power hungry and those models are TDP constrained.

Which means they should overclock nicely.  I'm sure they are binning parts to get as many high-end high-margin CPUs as they can as well.

5 And the 855's specs have been announced, and it was more or less as I remembered:  a 2.84GHz A76-derived Kryo 485 Gold, 3 more 485s at 2.42GHz, and 4x485 Silvers (A55-derived) at 1.8GHz, plus an Adreno 640.  Should be a powerhouse.
I'm pretty happy with the Mi Mix 2s (Galaxy S9 specs at half the price!) I ordered from Gearbest a few weeks ago, except for MIUI's goofy no-app-drawer, obsession with killing background apps to save power, and the fact that it constantly wakes the screen when I'm on the phone so I wind up face-dialing while I'm talking.
Seriously, it does a great job of keeping your notification bar empty because it kills all your games and other apps about a minute after they get backgrounded (meaning good luck running Map My Walk or something.)  To be fair, you can turn that behavior off on a per-app basis (which is another minor annoyance.)

6 Have you tried Nova Launcher?  Will fix most UI issues right up, including giving you the app drawer back.

Posted by: Pixy Misa at Thursday, December 06 2018 11:27 AM (PiXy!)

7 I've tried it on another phone but not this one.  I keep thinking about putting a custom ROM on it but you have to jump through hoops and ask permission for a boot unlocker.

8 Nova Launcher is the first thing I install on any new Android thingy.  My Huawei Mediapad had similar weird UI, and Nova Launcher made it all go away.

9 Ok, I just installed Nova and lost all my desktop shortcuts except for the search bar I never use, lol.
I don't think it's helping with the notification shade but I'll take any reduction in weirdness.

Posted by: Rick C at Thursday, December 06 2018 03:27 PM (Iwkd4)

10  You can get it to hide the useless search bar too!

Posted by: Pixy Misa at Thursday, December 06 2018 04:45 PM (PiXy!)

11 Sure, and I did--it's just a bit different from the usual way (long-press and choose "remove" from the popup instead of long-press and drag to a "delete" area of the screen).  I was just griping a bit about having to put all the icons I used back on the home screen. smile

Posted by: Rick C at Thursday, December 06 2018 11:31 PM (Iwkd4)

12 Yeah, I get that.  Worth it, though.
