Or maybe each layer holds 76GB, that'd be more like it!

There is also still a lot of work to be done before Project Silica can become a real product. Read- and write-operations need to be unified in a single device, and the amount of data stored on one piece of glass needs to increase. Microsoft isn’t revealing how much it has been able to squeeze onto the latest generations of the medium, but it is apparently not in the terabyte range just yet. Still, Rowstron is confident that Project Silica will lead to a break-through in storage technology. “I believe the future is glass,” he said.

8K has become popular enough that even Monoprice is now selling 48Gbps 8K HDMI cables for as low as $6.89 for 1.5 feet or 6 feet for $10.59.

https://www.monoprice.com/product?p_id=31231

$423.99 for the 330 feet 48Gbps 8K fiber cable that requires no external power source since the fiber to copper converter is built in the cable connector and uses power from the jack of the HDMI device.

https://www.monoprice.com/product?p_id=38629

Any future HDMI cables I purchase are going to be a minimum of 48Gbps compatible cables.

How do we know that Zeskit, SecurOmax, Belkin, Cable Matters, Monoprice DynamicView, Audiano are legit 8K HDMI cables?

You have to remember Belkin was claiming 48 Gbps on their cheap cables at the the Apple store that well over a year ago. So what application can you think of where you need a 8K cable?

There are no 8K sources, there is no 8K pass thru AVR's, only 8K upscaling TV's, some that still need a external box to utilize HDMI 2.1 interface that supports the full 48 Gbps.

Buyer beware on all of this until people need cables to support various HDMI 2.1 speeds.

[rachaeldeckard]

Just be aware that the official certification program for 48 Gbps aka "Ultra High Speed" cables has not begun yet.

Its likely a reputable brand like Monoprice will meet the spec but nothing is guaranteed.

Interesting ^ and thanks for your posts. Your comments are technically correct with worthy, and always realistic contributing comments.

On the subject of HDMI 2.1 48 Gbps 8K video with advanced audio are the leading reasons for the need of HDMI 2.1's extra bandwidth. Since we're stating terms, 8K is officially called "8K Hi-Vision HDR" or just "Hi-Vision HDR" and it requires HDMI 2.1 48 Gbps.

MediaTek 8K DTV SoC begins volume production at TSMC

HSINCHU, Taiwan R.O.C. — MediaTek (TWSE: 2454) and TSMC (TWSE: 2330, NYSE: TSM) today announced that the industry’s first 8K digital TV system-on-chip (SoC) manufactured with 12nm technology, the MediaTek S900, has entered volume manufacturing with TSMC. Built on TSMC’s low-power 12nm FinFET Compact (12FFC) process following the companies’ close collaboration, the S900 enables the next generation of smart TVs to deliver a richer and more interactive experience to consumers.

The S900 is MediaTek’s first flagship smart TV SoC, supporting 8K resolution and high-speed edge AI computation. Designed to help TV manufacturers create highly competitive flagship products, the integrated S900 supports features including AI voice-user interface and picture quality enhancements, enabling the next generation of smart TVs to deliver a vastly improved user experience.

TSMC’s ultra-low power 12FFC process leads the foundry segment’s 16/14nm generation technologies in reducing die size and power consumption, which is essential for digital TV applications. It provides a sweet spot between performance and low power that is ideal for enabling voice recognition and edge AI capabilities in consumer electronics, wearables and Internet of Things (IoT) devices.

“TSMC has been a key strategic partner of MediaTek for a long time, and their advanced processes have consistently enabled MediaTek’s industry-leading designs with innovative features which have satisfied the stringent requirements of our SoC solutions,” said H.W. Kao, Corporate Vice President of MediaTek. “We see a strong global demand for 8K televisions, and we are delighted to join hands with TSMC to collaborate on advanced technology for 8K TV SoCs to drive the growth of the premium smart TV segment.”

An 8K disc format is unlikely. Here's why

With the TV market slowly but gradually shifting from 4K to 8K, some are suggesting Ultra HD Blu-ray discs and players should follow suit. That’s not likely to happen, for a couple of reasons.

First of all, almost nobody has 8K TVs yet. IHS Markit pegs the household penetration for 2020 at well below 1%. Even in Japan, where the Tokyo Olympics will be shot and broadcast in 8K, the penetration will be just 0.1%. It’ll be a few years before there is a decent installed base of them.

Of course, you may say this situation is not unlike that of 4K about 6 years earlier, and yet we got the 4K Ultra HD Blu-ray disc format, but some circumstances are different. More about that in a minute.

Secondly, there is no 8K movie or TV content, and there isn’t going to be any any time soon. There is barely even any real 4K content and Hollywood is not in much of a rush to start producing it. Most movies are still finished at 2K. Even movies that are shot at higher resolutions (2.8K, 3.4K, 4K, 6K, 8K) typically get a 2K DI (Digital Intermediate – the main deliverable of the Post Production process, from which all theatrical and home video distribution media are derived) as CGI (computer-generated imagery i.e. graphics, also referred to as VFX or visual effects) are typically rendered in 2K (a resolution comparable to 1080p HD), because of a combination of time constraints and cost savings. Gradually, movies finished in 4K are becoming less exceptional but they’re not the norm yet and at the time of writing no Hollywood movie has been done in 8K yet.

It's funny but I don't recall HD or even SD upscales looking like blocky aliased trash on my steam-driven 4K TV? I got out the DVD for Wizard of Oz the other day (I was looking for the restoration featurette that's missing from the later Blu-rays) and decided to pop the movie in for a laugh. To my shock it looked superb when upscaled to 4K by the OPPO, and while it helps that Oz is in 1.37 so it's a good fit for the 4:3 frame size of DVD (i.e. no black bars or anamorphic shenanigans) it still looked far better than it has any right to.

Even the 'image database' revelation that's seemingly wowing people is old news, Sony have been doing this with their TV upscaling for years already. And while it may not be AI-driven in such a TV as my shitty old ZD9, that article readily concedes that the AI still needs a helping hand along the way to automate parts of the process, and it's not really doing the learning at the user end at all in Samsung's case, they have to 'teach' the processor at source and then squirt out new definitions via firmware.

I know that Penton et al will then reply with all the good it can do but this stuff just isn't some giant leap IMO, it's a game of increments and always has been. I've been chasing these increments for the last three decades, true enough - this is the first time in a long time I've actually owned a TV for more than a year or two, even my family pointed this out - but the tech has got to the point where I'm perfectly happy with "good enough". For those who have chronic FOMO and/or more money than sense (the two usually go hand in hand, oddly enough) then by all means go hog wild with buying an 8K TV but unless the Zed go kablooey tomorrow then 8K will be off my radar for a while yet.

I did some quick comparisons using test patterns and the LG Z9 does a better job upscaling 1080p than the Oppo 203.

On my 4K TV I had the Oppo upscale everything to 4K, but now I set it to Direct output so the TV can upscale.

[Geoff D]

Again though: does the OPPO's output (which is still having to be scaled further by the amazeballs TV anyway) suddenly look like blocky aliased trash? I love some test patterns but if you were played lots of different pieces of real world content, not just demo stuff but challenging pieces of content, in a blind test (not literally blind, natch) where you weren't told which was which then I wonder how often the 8K [scaling] would come out on top? (And no Penton I don't just mean in a test conducted by a Korean university with close ties to Samsung, lol).

[rachaeldeckard]

If you are referring to the article it is mostly marketing but the gist of what they are saying is true. When you increase the resolution of the display you also need to improve your upscaling algorithms. Doing a straight blow-up will result in larger pixels.

[Geoff D]

But again I ask: does the OPPO's upscaled output now look like utter trash in comparison, not with the patterns but actually comparing real world content back and forth?

[rachaeldeckard]

Trash? I don't know who is claiming that. The Oppo is already one of the best upscaling players. And as I said there was a definite and significant difference from test patterns. Enough to convince me to let the TV do the upscaling. I don't have the time or inclination to do frame by frame comparisons of every movie I watch. I am content with knowing that I have things setup to look the best they can be.

For what you spent I guess you have to reassure yourself often.

[Robert Zohn]

^^ @JohnAV

When you own LG's 88" 8K OLED you get reassured that you have the best picture quality every time you power it on.

Oh look who’s getting defensive concerning anything that might impact 8k now, it’s a joke. Guess now I have to wear protection!

[LordoftheRings]

Yup, it's that month of the year...November. It's snowing already in some parts ...
