isnt amd doing an entirely different chipset for itx? I'd imagine that would introduce some complications even if isn't that much of a difference and just 'less ram' and 'only one pcie slot'

Wait, ryzen's 4/4 structure is not internal to the chip, but rather from 2 4 core dies? No loving wonder

No, that was a poor use of words on my choice. I meant to convey that a dot over each of the two smaller rectangles might be better than one larger dot in the center. I absolutely should not have used to word "die" in my post and apologize, and have fixed the post.

No, it wasn't your words, I was confused from the line in the middle-- i thought it was from two dies rather than the 2 patches of solder the top two posts said

Ryzen has a 20 degree delta built into it for something. I'd be very surprised if this wasn't a result of that (hwmonitor being ignorant)

im kinda surprised (in a researcher sense) that they haven't gone with gaa sooner, since itd 'only' be what, an extra 2-3 masks to get that? theyd have to mess with the mandrels, but it shouldnt be too much.

RWT did a great article on GAA for anyone wanting read more on it: http://www.realworldtech.com/intel-10nm-qwfet/

Its a couple years old now but much of the information still holds up.

Seems like DK was expecting it sooner too but maybe it just wasn't practical yet.

Gah good loving lord that 'quantum well' gate growing a layer of si in the middle of all that? granted, you really only need one mask for all of that metal, but still.

Google says $490. That seems like a good price for that CPU and mobo and here I thought everything electronic was usually lots more expensive in the EU. Does it not include VAT in that price?

There seems to be some sort of commercialization of it already for solar cells of all things. Or maybe they're using something a bit different here, it was several years ago now I saw something about this and haven't heard much since, here is a paper on it but its way over my head:

yeah that metal fuckery is par for the course for photo-diodes. You need all of those energy levels to get the precise voltage/current/wavelength, though its not like LEDs need very fine features. However all of those different metals are expensive, especially when you have to make sure it etches away anisotropically through every layer so you can get that buried gate, form the very small features, etc

*sync over SiHS is something that I need to investigate. Straight up getting measurements is hard enough on a standard system. There are a few things I need to figure out, but I'm not sure how to do it (output stream from server, output stream from Link, server client latency, etc).

I'm super *duper* curious to see if there's a way to get a crazy cheap Freesync APU powered device hooked up to my TV as the client box for that. My TV has Freesync, so maybe it'll send Freesync all the way through. Probably not, though.

The SiHS thing is also more for putting games on my TV, I think there's a software that'll let you just move your mouse between desktop and laptop as a kind of extended screen, so maybe that'll be fun to play with.

Maybe a sufficiently low latency desktop instance could do it? Can you pass adaptive sync through virtualized video output? That would be crazy but also nice.

Or just crazy over buy and peg your frame rate limit where you want like I'm doing for older games?

E: I'm glad you understand the laptop thing. Sturdiness is so good.

gsync on the host or client machine? I've streamed from my pc which has gsync running, and it did fine.

Raven Ridge uses Vega, not Polaris, and the most recent "leak" indicates the M385X as most comparable in performance, or about 15% faster than the RX 550.

that sounds like a cut down rx 560

Are there any decent large-die-area low-power optimized processes (eg something similar to what you'd use for smartphone silicon that supports 150mm^2 dies or larger)?

I wonder if you could do a low-power micro-Navi on that.

gp107 was done on the same process as one of the top tier ARM SoCs. I forgot which one, though I want to say its whatever came after the one in the american galaxy s7? 832?

it says 11 but the marketing pic for the power has 3 inductors separated from the other 8 in a little box for the taichi. But fwiw it just seems to be a 'thing' they do with some of their boards. All of the boards I took a cursory look at are the same, at any rate.

AFAIK all of the existing discrete Thunderbolt controllers still need an Intel PCH in order to function. That's why PCI-E TB3 cards require this extra cable that hooks up to a proprietary header on the motherboard:



Whether this connection serves an actual purpose or is just there to lock out AMD and older Intel platforms is anyone's guess though.

with those 5 WIRE connectors, there is no way that's anything more than some dumb spi connection, which i can only surmise is a way to go 'Oh btw are you an intel thing?" or to change over pcie lanes on the fly which is dumb since theres no reason why that cant be a part of the handshaking for the card (unless theres no way of piggybacking that over the pcie connection???)

e: Apparently the pinout is "Ground, Platform Sequence Control, Platform Sequence Control, Plug Event, Power"

stuff separating almost certainly means the emulsion settled-- its not an entropic phenomenon in the slightest. Just mix it back up! But regardless, any aio will come pre-pasted so you only need a tube if you gently caress it up or need to take it off again for whatever reason.

r/AMD is hosed in the head because Steve only ever poo poo on the 1700X and 1800X for being overpriced relative to the 1700, and was iffy on the 1700 from a pure gaming standpoint as the 7700K performs better for a similar enough price. Oh and he rightly pans AMD for Vega. Otherwise I've never seen him explicitly down on AMD and instead has been supportive of basically the 1700 and down, and even Polaris as budget options.

I suppose tho I could totally be wrong and they're churning out tons of chips and relatively few TR packages.

On the substrate, I wonder if they're even connected at all to the PCB or just pads on there.
Cos if the wiring is hooked up it'd be another vector for package faults.

14nm success rate for something that's not on a cheaper, fewer mask, process is ~75%. That includes ALL dies which pass, whether its bin 1 or one that fails one thing like voltage, but not so egregiously that it would take 150W to hit 3.8ghz or whatever. For zen, the dies are 213mm2, which means there are approx. 300 dies on a wafer: 225 that pass, 75 that outright fail. I think there's more than enough dead dies for threadripper Hell, even if they got things going amazingly up to an 85% yield (the highest i've personally seen for a 14nm product was 86-88% for a 'budget' arm soc), there'd still be enough for like 20 tr processors per wafer

nodes are marketing names at this point this is very likely "10nm" FEOL with "14nm" BEOL or somesuch like tsmc 16nm used older BEOL tech

Heck intel is basically hosed with 10nm, 14+++ is gonna be better than 10 for everything but extreme density/power needs (apparently SemiAccurate has the scoop on whats wrong but i am not spending 1k on that)

And I was just about to make this point lol. It's almost certainly that either they decided the process improvements were advanced enough for 14+++++++++ or whatever to merit a new marketing name, they decided to implement triple/quad patterning for FE and kept double for BE 1/2, or both.
