Why do people pay $20+ for the latest variant of thermal grease, just to turn around and splat it onto their lovely aluminum heatsinks? I mean, copper is a superior conductor and costs less than $3.00 a pound.

Ok so I won't pour any food into my CPU but if there are some "more precious" precious metals I can waste money on for a heatsink , let's hash out what that looks like please

The only benefit to using less and spreading by hand is to get more applications from a tube. But AFAIK using too little is more likely to cause temperature problems from dry spots than too much.

AMD confirmed that the R5 1600 "AF" SKU found in the wild is a 12nm Zen+ die. It is a 2600 with 200mhz lower clocks stock... but you can overclock it exactly the same as a 2600. Same cooler as the 2600 in the box too. So yeah, at $80 at microcenter (plus $20 board credit), it is a pretty drat great deal, and better than the APUs if you aren't planning on using the graphics. King of the value segment, and pretty much makes every CPU from Intel or AMD under the 3600 obsolete. https://www.youtube.com/watch?v=wRO_AUdmfis

There were recent news/rumors about Apple moving all their chips to TSMC 5nm, freeing up a lot of 7nm wafer capacity at TSMC. Allegedly a certain CPU manufacturer booked a very large part of it, making them TSMC's largest 7nm customer.

As other manufactures move to 7nmEUV AMD can get absolutely huge volume on Zen2 compared to Zen3, and it may make sense to support Rome longer and more vigorously than Genoa until Zen4 drops.

Does AMD manufacture the console's APUs or are they manufactured under their respective corporations? MS and Sony should start ramping up production soon for the 2020 EOY launch.

I've never been sure about this, because I've seen contradictory news stories. IIRC I read a story not too long ago that said the chips for xbox & PS4 had moved to different fabs. But then there's old stories like this where it seems like AMD had more say in the matter. Which might have been the case in 2014 -- maybe part of the contract was to use GloFlo because that was back when AMD was having trouble using up their wafer agreement?

Is the reservation at TSMC (confirmed N7 for one of the APUs at a Dr. Su presentation) done under AMD's name or Sony/MS? So is the huge reservation of TSMC N7 production for the consoles' ramp up or for AMD's own production?

It's not a licensed design. At least, not in the same sense as the Hygon chips. This is AMD's semi-custom division at work, where they take bits and pieces from the CPU and GPU divisions and boil it down to a single monolithic chip to send off to the fabs, get back, package, and then hand off to Sony/Microsoft's OEMs.

Shaocaholica posted:So when will the big OEMs start offering AMD flavor workstations? Dell/HP still seem to be intel only. Dell has them, they are the ones that end in 5, there just aren't many options. Dell also has a dedicated AMD page. They are pretty hidden and you have to look for them, but they exist. There's very little customization and any rep I've spoken to pretty much refuses to budge on price but will discount the Intel until it's a better value saying they have rebates with Intel but AMD isn't offering any. I might just have lovely reps. Biggest issue is you can't filter for them so you have to go to the main page and just happen to click a model number ending in 5 then click more info and realize it's an AMD. I feel like either major OEMs are just slow to change and are used to Intel only, or Intel is doing something underhanded. I want to believe Dell / HP are just waiting to see if there's further problems but I bet they also want to sell computers instead of preorders. The last few years I haven't been able to get any desktop / server quicker than 2 months unless I get a Walmart special. (and have! They made terrible temporary workstations for new hires until the real hardware came in). I'm hoping it's just chicken and egg and they don't see a demand because they only offer anemic AMD configurations and no one is really calling asking for custom.

Not that I'm surprised they're doing it again, but they lost a lawsuit and had to give AMD a bunch of money.

Intel and Dell can't deliver systems right now, so they're probably desperate. I'm getting 30-60 day lead times on some processors.

I might just have lovely reps. My wife's research lab had a similar experience and they ended up ordering a couple of Intel big boxes. List price was the best price possible for AMD stuff, but Intel stuff was discounted so deeply that core for core, clock for clock it was the same price as Epyc. At that point, you go Intel. Edit: If you guys are at HP shops, I'm curious what pricing CDW is giving you. I've seen advertised prices under $2k for 7402P / 64GB DL325s: https://www.cdw.com/product/hpe-proliant-dl325-gen10-rack-mountable-epyc-7402p-2.8-ghz-64-gb/5736036 Twerk from Home fucked around with this message at 18:06 on Jan 4, 2020 |

The 'rebates' thing was the same trick they pulled the last time around, except they were way too obvious about the rebates only being available to OEMs who didn't use AMD CPUs. And that's how they lost an anti-trust suit. I'm 100% expecting they're doing similar deals now but with more subtle and probably-not-illegal restrictions, something like the big rebates only when a model line is all intel. That would explain the visible effect of AMD being locked out of high-end product lines. OTOH this is how intel competes on price: only when it has to, and in secret. Stuff like the 10980 getting a $1000 price drop shows where their margins on high-end parts are. They can discount their stuff to be competitive, but they don't want to. If they can preserve their inflated price structure until AMD does Bulldozer 2 Electric Boogaloo, they can go right back to record profits.

I don’t think anybody actually buys those things anymore. Every corporate customer I see these days buys laptops for everyone, even if nobody works from home. The only towers that get bought are for labs or engineers, and generally are Xeons.

AMD haven't helped themselves by lagging behind on their APU line. The world of non-workstation business desktops seem to have decided that separate GPUs are an unnecessary expense; here AMD still only offer four cores which plays against their advantage. A 3700X APU would stand out a lot more and give reason to build lines around AMD.
