AMD - Zen chitchat

[CAT-THE-FIFTH]

AMD CPU and GPU marketshare has seen some decent increases:

GPU seems to be in-between a GTX1050TI and a GTX1060 in performance.

Dell also CBA making more than a few AMD systems it appears,as Intel is bigger:

Worth noting that the interviewee here is the CTO of Dell EMC, rather than Dell Inc.. Given EMC is an enterprise storage and virtualisation company (albeit a wholly owned subsidiary of Dell) his worldview is likely to be somewhat different to the people in charge of Dell's consumer and workstation line-up...

It hasn't stopped the former Intel chief engineer going out and using it to spread fud about AMD on Twitter,and didn't we see the same lame excuses back in the day?? Isn't that the same area Intel has identified as a "growth area!" ??

It seems Baidu and MS don't agree with him,since they are early adopters of Epyc,and so is QNAP for their usage of Zen based products. Guess what these companies use them for??

Edit!!

I suspect its more the case Zen based products would end up being cheaper than comparable Intel ones,and that would force Dell to drop pricing on the Intel based ones,and that would probably annoy Intel as they would have to drop pricing,and if they didn't Dell would have to drop margins.

Looks like the new Intel control panel is basically a blue version of the AMD one!!

Edit!!

Some benchmarks of the Acer Nitro 5 which has an RX560:

It looks like the chassis has enough cooling for the Ryzen 7 2700U in the laptop to run at a 25W TDP.

Pmsl i have no words. I really do hope Amd can do two things, continue after 2020 to produce great cpus and really from 2019 start slapping nvidia about a bit .

all i care about is the cinebench score (actually use cinema4d ) .. wait till april or take a 1700x/1800x now ..

Yeah,its quite funny!!

Edit!!

Ryzen 7 2700X clockspeeds apparently leaked:

Runs at 3.7GHZ~4.1GHZ it seems.

Not sure if i should get the 1800x now .. or will the extra ipc/mhz speed be worth it .. i suspect the 2800x will hit 2k in cinebench r15

The first Ryzen 3 based laptop has been released:

Ryzen 3 2200U goes down to 2C/4T and only 3 Vega CUs. Unless yields are very bad, they must be throwing so much potential away there.
Two dies to rule them all for now, but if they get their volume up making a much smaller die would be essential. Getting over 200mm² down to under 100mm² should be possible with half the dies and 3/10 of the CUs.

The the die is new, it should sort itself out in a few months. Not sure what the normal vega yield is like but 3 to 8 Cus should be less of an issue than the full vega core

Without fully understanding AMD's financials it's hard to say for sure, but it's not as simple as just chucking out an arbitrary number of die variants for each market niche. Exacerbated by current cutting-edge nodes, mask costs can have a substantial impact to margins - the target market needs to be large enough to offset the initial costs whereas conservative binning is very flexible and allows greater selectivity of the higher-end parts. In addition, yet another die variant adds complexity to inventory management, but again binning is flexible and allows fast response to market demands vs lead time measured in months for wafer orders.

It's not necessarily correct to attribute segmentation/binning to yield either - Intel have long been heavily stripping features from cheaper CPUs which have little to no impact on yield e.g. SMT, instruction sets, cache sizes, etc. Same for their chipsets which generally all use an identical die. Intel still had plenty of market for dual core dies though given their reluctancy to allow 4 cores in 'mainstream' products (at least until competition forced their hand) and selling dual cores as 'high end' in the laptop market.

Stripping half of the cores and most of the CUs wouldn't necessarily save as much as 50% of the die anyway - take a look at the die shot.

Okay, that's a fair point.

So the one CCX takes up ~19.5% of the die, and all the Vega cores take up 31.3%.
Meaning half the die is taken up by fixed stuff. Half the CCX would only save 9.7%, and 3/10 CUs about 21.9% for a saving of around 32%. At around 210mm² for Raven Ridge, that would make such a die about 140mm² still a lot bigger than the Sky/Kaby/CoffeeLake 2C dies which are around 99mm².
I'm sure once AMD's volumes are high enough it might eventually be worth their while to make smaller dies - although then again if they want to hit, for example, a 5W target they might be better off with 6CUs running slower etc. That is, they have plenty of options.

The first Ryzen 3 based laptop has been released ...

$680 for a Ryzen 3 2200U/8GB/1TB HDD?! Even for a 17"FHD laptop that looks a bit insane. The $900 option Ryzen 5 2500U/16GB/2TB looks quite reasonable though....

[watercooled]

I could be wrong but I suspect AMD are aiming more to push quad cores into mobile rather than their dual cores so they might not want 2C volumes to get that high. However maybe if they also use a cut-down die in their embedded products it could make more financial sense?
