    Perhaps he just needs views so he made a video complaining about completely superficial things. Like the cooler is ugly from this angle if the card is out of the PC case.

    Maybe it's that, but we don't know his relations with amd/rtg. Maybe he got screwed over about something or I don't know...

    I'm too old for youtube, I belong to a generation that learned to read.
    Interesting pictures nevertheless.

    Generally too much emphasis on looks (RGB anyone) these days IMO. Like i care how the cooler or card looks as long it does a good job.

    Nah you just like to be able to extract information in the order you want, filtering what you want, and at an appropriate speed.
    Instead of sitting through some random muppet's train of thought and narrative

    Well AFAIK they supposedly didn't go anywhere after being purchased by ATI almost 20 years ago. They're part of AMD now, or at the very least their IP is.

    My viewpoint on this is that the gaming market has shifted and what we're really seeing the product stacks shift to match. For better or worse there is a market of people who want performance and they willing to pay the costs for it whether that's purely monetarily or through other considerations such as the higher nominal power consumption numbers. This means we're going to see the product stack stretch even more going forward, and even more so should we eventually move to MCM GPUs (more on this a bit later). Remember when graphics accelerators first came about the graphics stack was really tight by comparison (1 product per gen in some cases).

    If you want a lower cost (nominal) graphics they'll still have products that serve it. If you want a lower power graphics card (whether for SFF, noise, or whatever) they'll have products that serve it. It's just that people will need to psychologically/emotionally come to terms that they'll sit lower in terms of relative performance vs. the absolute highest performing tier in a given generation for those that are willing to go to the extremes in cost.

    Swinging back to MCM GPUs why would this get worse? Well if we were to hypothetically have a 4x75w (this like the lowest PC discrete GPUs atm) that is already 300w. But why would you stop there from a vendor perspective? There's going to be a sizable market willing to pay for more performance. A 2x200w of more mid size chips (eg. Navi 10 range ) config is already 400w. Remember we had 2xGPU cards in the past and they were still viable products (eg. the 500w $1500 2xHawaii 295x2) and that was with horrible scaling and support issues that were software dependent. A 250w

    Asking because the MoSys patents were ~20 years ago? Good question.

    edit:

    As it gets harder to shrink, maybe it's something they ought to be thinking about. hm...

    Unlikely, 1T-SRAM is DRAM with a SRAM interface, and DRAM uses capacitors which don't scale down as well.

    Cheers

    The quad-density ones are from later than that, they only showed in 2003 I think.

    But is AMD unable to license 1T-SRAM-Q from MoSys? I came up with 1T--SRAM simply because the density is much higher than regular 6T-SRAM. The Gamecube's Flipper GPU had a "humongous" amount of 3MB of 1T-SRAM inside a 100mm^2 chip with 51 Million transistors.
    If that was scalable (according to @Gubbi it isn't, though), then 128MB of it would mean nothing in a >300mm^2 chip at 7nm.


    Ok, I wasn't aware of that.
    The Wikipedia page shows pretty decent scaling on 1T-SRAM Q but only down to 45nm.

    Ah whoops.

    Gosh, now my mind's flashing back to Z-RAM & A-RAM. :D

    Anyways

    Is that cooler 3 slots wide or merely 2.5?

    Seems like it's the same set of photos JayzTwoCents leaked in his video, but Jayz only showed one of the photos.

    It's 2.25 or under, not sure if it could be counted as 2 slots though

    So, anybody being able to pixel-compare that naked ES board to this new set of pictures of Navi 21?

    Those two screws can be found on the ES board. However, comparing those small elements on the chip back is a bit tough.

    Whats the latest on N21 and bus width? Everyone still on the 256bit train? As a contrarian I have to call BS.
