Arzachel posted:I don't think Ryzen hexa and octa cores are worth it for gaming until they figure out how to keep critical tasks from migrating between the clusters. You can do that manually with a programme like Process Lasso. If what SwissArmyDruid says is true, though, that the 6-cores will have one core disabled from each CCX, that's a disappointment. 2 enabled on one, 4 on the other would be perfect, because you could assign Windows processes to 2 on the same die, and then have all your other tasks running free on one quad core CCX, avoiding that problem of migrating between them.

 https://www.io-tech.fi/uutinen/6-ytiminen-ryzen-prosessori-teknisesti-mahdollista-toteuttaa/ That's the layout these guys said their sources said AMD was looking at. quote:We have confirmed from our sources that AMD’s upcoming Ryzen processor can be technically configured as 6-core model. It is possible to disable each CPU core separately together with dedicated L2 cache from CCX without affecting shared L3 cache. Possible L3 cache configurations are 1/1 (8 MB), 1/2 (4 MB) or completely disabled. Basic rule is that both CCXs should have similar CPU core and L3 configuration for example both should have 3 cores and full 8 MB L3 cache enabled (6C & 16 MB L3). Which means that 4-core Ryzens are likely to be 2 + 2, and not "all on one CCX" parts. SwissArmyDruid fucked around with this message at 12:42 on Mar 15, 2017 |

Is the separate l2 cache going to cause problems with more highly threaded games, going forwards? I don't really see how it can't.

dont be mean to me posted:Why is the 1600 a 95W part and the 1700 65W? 'lol AMD TDPs' notwithstanding. 1600X is a salvaged high leak binned 8 core, with two cores not working or disabled. It is clocked at the same frequency as the 1800X. 1700 is a low leak binned 8 core, that is clocked much closer to the most efficient state for the architecture (which is a high IPC low clock/TDP design pushed to all market segments).

SourKraut posted:I was excited about possibly getting a R5-1600X, but reading above, it sounds like it might be a crippled chip? Not really, it's just people were hoping for a chip with a 4/2 CCX split instead of a 3/3 one, this is because passing threads between the CCXes is much slower than within CCXes. If you are doing workloads that will benefit from the extra threads the chip should still be very good at that and while still behind Intel's offerings in gaming it should be a decent chip for that too. Ryzen is really a nice chip for mixed workloads, but if you are just gaming Intel is still going to be the better choice for now.

Potato Salad posted:16MB L3, 6c, 65W for $220? Yeah, this parts are much more competitive, and like you said, loving the huge cache. That said, they still need actual clock increases over the 8-core parts, but it seems like their process just won't allow them. Hm. Once they get these 6-core parts to 4.5GHz or so, there's pretty much nothing holding them back. vv It is, I'm just saying that a lot of people will still shy away for gaming reasons because the single-thread performance still isn't up there due to the slightly low clocks.

Yeah, the later stepping of these same dies should help them find a couple hundred more MHz. I wouldn't expect anything game-changing but for launch silicon this is pretty great, especially at 65W.

Don't care about a 4 GHz wall with mobile parts and to a lesser extent, servers, but I worry the APUs will bring last-gen perf to throw down with Cannonlake, when ideally it should be Zen+ or Zen 2 or whatever the hell.

Doesn't Zen L2 cache always run at full clock speed? I wonder if that is part of the reason why it won't go far past 4.0-4.1 Ghz. AFAIK Kaby Lake L2 cache frequency (uncore) also tops out around there but it's on an independent multiplier.

The only people buying AMD laptops currently are idiots who can't evaluate what is good/bad for a computer so naturally you're going to make a poo poo laptop with the current poo poo processors. You're fleecing them already by selling them a bulldozer laptop, you might as well fleece them on every other part. If it is an actually good processor, its worth targeting people who know what makes a laptop good when using the processor.

Aren't AMD laptops, if you can get one with the best APU offering AMD offers, better GPU wise then say a midrange Intel with a 620 or whatever the low end iGPU is for those? Sure the CPU is going to suck, but if you just wanted a basic media consumption device, is AMD really that bad currently in the laptop realm if you aren't buying a i5+? *Have not done any research because all I have been looking at are 1070-1080GPU powered laptops for replacement of my old i7-720QM-5870M beast...

I'm talking about build quality, tiny batteries, poor low res screens, etc. Carrizo is an already existing reasonable AMD solution, but try finding anything that has a build that's on par with the best Intel laptops..

AMD is absolutely better for basic media consumption and browsing or whatnot at same price points. The problem is, the kind of laptop OEMs put AMDs in will fall apart after 6-12 months. e;fb

So for most people except those trying to squeeze out every single last FPS, the 1600 is going to become the best value CPU right? With cooler included it's a pretty solid proposition.

They need to fix memory compatibility with their controller. Can they patch this with microcode or a bios update? As is it will create a problem when the more numerous R5 users can't get over 2400 with their 3000+ dual rank kits they already have.

You are right about a lot of crap laptops, though if you sift through enough of them, there are at least a few that have 1080P screens and aren't made of the cheapest plastic you might find on a low end Acer or something. Asus made one... Still pretty sad but bang for the buck its not terrible. Though hopefully if mobile Zen becomes a thing then the OEM's might take notice. Only time will tell currently as the iron out all the bugs and chips get made.

I hope someone sticks an 8 core chip in a laptop. Would be nice to have a semi-portable workstation, even if it gets as bulky as some of those gaming laptops with dual 1080s inside.
