I think the reason is a I/O limit, rather than space to provide just a basic GPU... also the encoder block was not needed.

I think the reason is the same one of why Ryzen APU are limited to 8x mas PCIe... i belive they are using the pci-e lanes to provide video output.
That's the other thing I think people miss. AM4 is a huge compromise to keep the Zif socket and maintain support for APU's and CPU's on the same platform. I don't think their is enough IO, pins, or basically anything to support a Video output on Mattiase and honestly I don't think it makes a difference if it Vega 3 or Vega 11.

Which, last I saw a comparison, was the worst of the three. All three are also only as good as the support in software. Both Edius and Premier have support for Quicksync, and at least according to HardwareCanucks, it's about twice as fast
. iirc, Premier also has or had support for cuda as well, but the last numbers I saw on that weren't anything to write home about. Edius uses the QS hardware for decode acceleration as well, and that makes it a lot easier to have a real-time 4k60p timeline during editing, which my 2950 struggles with (after a few edits). In my opinion, that's more valuable than encode acceleration, because I'm happy to let my 4k encodes run overnight.... Even better would be if Neat could be hardware accelerated -- denoising is currently an absolute hog.

All three hardware solutions suffer from being restricted to 4:2:0 video, and so I've frequently dropped the idea of "someone" leap-frogging this stuff and, say, replacing a few of those chiplets with some dedicated hardware for 8k-sized, 4:2:2 and 4:4:4 hardware decode/encode. I think I was also pretty careful to mention that they need to engage software vendors, otherwise the hardware is going to wind up being pointless. I've also spent some time in the Edius forums asking for them to get nvenc working (nvenc has actually seen updates, I haven't heard hide nor hair of VCE :shrug: -- I think AMD has other struggles with their gpus).

Thus far, only Intel has gotten traction. :sigh:
In the past years I always wanted to live in a world where all that intel and its collateral people can say as a saving grace is quicksync

I kept hearing originally that today would be the review embargo lift for Zen 2. However, it seems like there would have already been some reviews posted. In the last week, rumors have shifted to the embargo being lifted on release day.

Do we have any official date/time? Clearly, it seems to not be today, as they would have almost certainly been released by this time of day.
it was always 7th July, but I have no idea about what time. All Su has said about today wa the start of pre-orders. But I have yet to see one

A compromise, which was most likely born out of financial considerations / boundaries rather than out of humanitary good will, but it benefits almost all AMD customers hugely, nevertheless

Apparently this is misinformation. She never said anything about preorders during computex. This rumor comes from some guy at gamers nexus, or so I’ve heard. So 6 more days for us.

The term "pre-order" almost guarantees that we can order sometime this week.

It was a specific request of the OEMs. Not to beat a dead horse. But this also plays a part in the A320 convo's from earlier. AMD had almost no penetration in the OEM's. They went to them and said "Hey I am making a new platform and I want to know what you guys would like to see from it". They wanted one platform for CPU and APU, they wanted it Zif for cost, and they needed a compatible APU before RR (Bristol Ridge). AMD told them it would compromise IO on both APU's and CPU's to keep it on a zif socket. They were okay with what AMD had to cut out. The point that circles back is its not just a compromise in technology internally or financially. It's a compromise with the OEM's to get buy in on their new product.

AMD has VCE.


The format is h.264. x264 is a software encoder implementation of it. Quicksync, NVENC and VCE are hardware implementations of a couple of codecs, one of which is h.264.

I tend to use them interchangeably even if that is not correct. You know what they say about old habits. I should probably work on that though.

I have a feeling AM5 will be LGA. By then AMD won't be at the mercy of the OEM's so much.

seeing that the downsides turned out to be not too big of a deal, I'm quite glad they did so

The estimate of 4 mm2 per CU should be pretty good. It's either 4mm2 or just under but close enough to round up. You can see the 11 rows in the RR die shot form the 11 CUs (the very green area measuring a tiny bit above 40mm2). And this area is just somewhat bigger than the CCX area, which is just under 40 mm2 (mobile oriented CCX has half the L3 versus PR/desktop oriented Zen CCX).



https://en.wikichip.org/wiki/amd/ryzen_5/2400g

The DE and ME together are between 4 to 5 CU's worth of area. The memory controller and Phy are present on the IO hub anyways. The coherency logic on a single chiplet hub can be skipped. So an OEM and mainstream MCM 6c-8c APU oriented 6CU hub would hit the sweet spot. I think 25W-65W cTDP should be doable. 25W-50W for a BGA variant; no OEM could complain.


3, 6, and 11 CU total iGPU area would add just an estimated 31mm2, 43mm2, or 63mm2 to the IO hub.

(8 or 10 CU would also be options, and take up mm2's in the low to high 50s. I think 12nm CUs can clock high enough that anything over 8CU is overkill, unless users go with pricy high frequency DDR4.)

If they wanted to, they could launch such a 4000 gen APU this Xmas. And monolithic Navi 5000 gen APU could follow up year-end 2020.

I've never been big on pre-ordering anyway. I like to give them a month or two to get all the bios patches, Windows drivers etc in order. Let the impatient do the beta testing. ;-)

See the builders thread. NO pre-orders. I was wrong.

7/1 was the unboxing embargo. 7/7 is for reviews and product launch.

Yeah i think AM4 was designed from the ground up to have both APU and pure CPUs whiout IGPs and that it is. There is no enoght pins. OEMs probably dont care so much, they have the APUs, they have Intel and they have Nvidia.

The only problem im seeing with this is that the motherboards has to wire the video outputs to the pci-e data lanes, what would be a wierd thing to do if you actually have a CPU and you are actually using them.

this guy has a low-end sku(3600?) and has 1.664v@5.1Ghz, but they also said temperature is not good and OC headroom is very limited.

now I begin to doubt Chiphell is not a reliable source anymore, all good&bad news flowed out just from this, I wont quote their rumor again. I must say sorry here about the '5Ghz' rumor(whatever 1core or all core) which was from them

edit:
typo:1.64v -> 1.664v
author said he used LN2 to cool it

That s 90% more power than at stock 4.2GHz, if a 3600 use say 65W@4.2GHz then this sample is at 125W@5.1GHz.

Curious why you think they will go lga, it was my understanding that pga and zif were a more durable connector due to pins being more substantial in size on pga than lga. Is there a major bandwidth difference?
