    TSMC to Enter Mass Production of 6th Generation CoWoS Packaging, up to 12 HBM Stacks

    TSMC, the world's leading semiconductor manufacturing company, is rumored to start production of its 6th generation Chip-on-Wafer-on-Substrate (CoWoS) packaging technology.
    As the silicon scaling is getting ever so challenging, the manufacturers have to come up with a way to get as much performance as possible. That is where TSMC's CoWoS and other chiplet technologies come.

    They allow designers to integrate many integrated circuits on a single package, making for a cheaper overall product compared to if the product used one big die. So what is so special about 6th generation CoWoS technology from TSMC, you might wonder.
    The new generation is said to enable a massive 12 stacks of HBM memory on a package. You are reading that right. Imagine if each stack would be an HBM2E variant with 16 GB capacity that would be 192 GB of memory on the package present.
    Of course, that would be a very expensive chip to manufacture, however, it is just a showcase of what the technology could achieve.

    Samsung and Stanford Uni create 10,000ppi OLED display tech

    In the not too distant future tech enthusiasts might be keenly discussing the merits of devices with 'metaphotonic OLED displays'.
    This is a new kind of OLED display which branched from research into ultra-thin solar panels.
    Key attractions of the new metaphotonic OLED displays are their very high pixel densities (up to 10,000ppi), as well as being brighter and offering "better colour accuracy," than existing OLED tech.

    [​IMG]

    To create ultra thin and efficient solar panels Stanford University materials scientist Mark Brongersma decided to try and take advantage of the fact that, "on the nanoscale, light can flow around objects like water".
    The theory has worked really well in solar panel design and thanks to some lateral thinking by Won-Jae Joo, a Stanford visiting scientist from the Samsung Advanced Institute of Technology (SAIT), it looks like the nanoscale tech will impact the OLED display market.

    "The crucial innovation behind both the solar panel and the new OLED is a base layer of reflective metal with nanoscale corrugations, called an optical metasurface," explains the Stanford News blog.
    "The metasurface can manipulate the reflective properties of light and thereby allow the different colours to resonate in the pixels. These resonances are key to facilitating effective light extraction from the OLEDs."

    Having all the pixels of the same height makes the manufacturing process simpler and aids large-scale as well as micro-scale fabrication.
    In tests of early lab made metaphotonic OLED displays, Brongersma and SAIT researchers have created pixels with a higher colour purity and a twofold increase in luminescence efficiency compared to TV OLED tech (colour-filtered white-OLEDs).

    [​IMG]

    Samsung is currently busying itself creating a full-sized display using this new nanoscale tech.
    The metaphotonic OLED displays are expected to become particularly appealing in devices such as HMDs where the display is situated very close to the eye and high ppi figures are particularly welcome.

    Important part is not that it generates bit better color space.

    Important part is: Price it generates this better color space in comparison to existing technologies.
    And technical properties like achievable refresh rate, power draw, degradation over time, ...

    In two days, the AMD RX 6000 series graphics cards will be officially released, but this is only a paper announcement. There is still a little time before the evaluation is lifted and the product goes on sale, but AMD has not notified the specific time point.

    According to the latest information obtained by Bobantang, AMD will announce all the information of the RX 6000 series at one time on October 28th, US time (early morning of October 29th, domestic time), but the listing time in China will have to wait until November. Around the middle of the day, the conventional evaluation performance will not be announced until then.

    The first models include RX 6900 XT, RX 6800 XT, and RX 6800, which are all based on the Navi 21 core, and there will be the RX 6700 series behind, which will use the Navi 22 medium core.

    The RX 6900 XT is the most anticipated flagship card, but it can be confirmed that it does have only a public version of the card, and the number is limited , there will be no non-public version, AIB brand vendors can only get the RX 6800 XT.

    The performance of the RX 6900 XT is expected to basically catch up with the RTX 3080, and the RX 6800 XT can be tied with the RTX 3070 at best. This means that AMD has strategically abandoned the battle for the commanding heights this time and directly competed in the mid-market .

    It is still unclear why AMD did this. It is estimated that the Navi 21 XTX used in the RX 6900 XT has limitations in one or more aspects such as yield, power consumption, and performance.

    According to rumors, the RX 6900 XT has 80 computing units, 5120 stream processors, a core game frequency of 2040MHz, an acceleration frequency of 2330MHz, 256-bit 16GB GDDR6 video memory, and an equivalent frequency of at least 16GHz.

    RX 6800 XT is code-named Navi 21 XT, 72 computing units, 4608 stream processors, core game frequency 2015MHz, acceleration frequency 2250MHz, and memory as above.

    RX 6800 is codenamed Navi 21 XL, 64 computing units, 4096 stream processors, core game frequency 1815MHz, acceleration frequency 2105MHz, and the video memory remains unchanged.

    The next step is RX 6700 XT and RX 6700. In terms of specifications, we only know that the former has 40 computing units, 2560 stream processors, and 192-bit 12GB GDDR6 video memory. Others are unknown.

    Its so hard to really know where these new cards will end up performance wise. But even if the 6900xt is give or take 10% within the 3080 and the 6800xt the same with the 3070, its a huge improvement over the last couple of generation releases. That is a massive feat on its own. Because competiton breeds innovation. So come on AMD, wow us all like you did with RyZen.

    At this point I'm really interested in getting a 6900XT, wherever it ends up compared to the 3080.

    The rumours about limited availability are what worry me though.

    Same! I want 6900XT, rumors about it being ''limited'' and reference design only are worrying tho.

    Limited Edition will mean that there is indeed LC XTX like Vega or Fury.
    Less than 8k units was manufactured (Don't know exact number, it's more or less with emp. on less)

    5700XT (Navi 10) had plentiful supply due to good yields and production capacity. Navi 21 Chip may have reasonable production capacity as Navi 10 is no longer made.
    Question is yields as it is larger chip. But then if there are fewer 6900XT, there will be more 6900/6800XT/6800 based on same chip. (That's if there is actual 6900.)

    But considering there are no news about chip full that would have around ~60 CUs, everything is possible.
    If yields for Navi21 sux, AMD can go with 80/72/64/56 cut-downs. Or other way of disabling problematic parts.
    People originating rumors about 80/60/40 variants are now very quiet about it. And that's problem with this launch. Not that AMD did not leak details themselves. But because TY click magnets spread fake data.
    Tomorrow, everything may end up being very different. As today's state of things is just consensus. And even now, it is rather unstable one.

    RT is what maters most for ATI IMhO.
    We need good performance with RT Enabled Games.
    I don't want to Wait to Play: Control, Metro, BFV and other games.
    I need 70FPS with RT at 1440p.

    If don't then nV will outsell ATI yet again.
    For me it's 3080 or Big Navi (for now).

    Control is nothing special. Metro does not need RT and BF5 is rather trashy.
    From F.E.A.R. games, 1st one was the best even while having worst graphics. There is performance to gaming and there is visual necessity for story telling.
    (And I would rather seen/play next installment of "The Suffering" than Control.)

    Games that focus only on visual without using it for story telling are doing it wrong way. At least, visuals should set atmosphere. But for that DX-R is still not needed.
    It will become important once games can't be played without it. Or at time there is enough performance for game to actually stop looking like rasterized one.
    (Not this generation.

    Currently, only benefit there is comes from easier setup (cheaper game to make). But for that, we pay on HW side and games are not any cheaper.

    That's why I care little if game has it as long as it does not look worse than traditional games when disabled. And when that's the case, no point in paying for visual downgrade.

    13 RT for now. Also in a lot of the games the implementation doesn't really change the look of the game that much. Control still best example of RT and you lose nothing imo playing it without it.

    Opinions vary, but most will enable RT rather than do without.

    Depends ofc on the implementation and at what penalty it comes with.
