Of course I know what flex mode is. For a console, it's not CLEAN, it would be a kludge at best.

A SoC with six gddr6 controllers (=384bits) is expensive, a lot more than a chip with four or five controllers. Gddr6 controllers are not cheap when it comes to die area and power consumption. As an engineer, you want to get away with the fewest needed to do the job.

With 16GBit gddr6 parts, four controllers give you 16GByte, five controllers give you 20GByte, six give you 24GByte ram (all full speed at all times). You are suggesting that MS builds a very expensive six controller system with only 16Gbyte ram (not at full speed all times), while a significantly cheaper five controller system would give them 20GBytes, 25% more ram (at full speed any access). I don't think MS engineers/beancounters are anywhere near that dumb.

I'm glad you're here, Xbox anaconda just leaked, they not using Flex mode as I thought. But Anaconda is 16GB Vram (13GB for games so flex mode is out) and they mixing 1GB and 2GB Vram, probably on a 320-bit bus or 384-bit bus. But I'm not sure what they are doing. Since you the expert you should figure it out :)

Yes I'm well aware of 6 64-bit controllers are expensive, but Anaconda is 12TF so it need high amount of bandwidth.

New Update from  " Thurot " ( Microsoft insider)  https://www.windowscentral.com/xbox-scarlett-anaconda-lockhart-specs

"In the 2019 reveal video, Xbox cloud architect Kareem Choudhry said Scarlett could "eat monsters for breakfast," and indeed, Anaconda looks as though it will be able to. According to several sources familiar with Microsoft's plans, Anaconda is targeting around 12 teraflops (TF) of computing power, compared to the Xbox One X's 6TF, and the Xbox One S's 1.4. Lockhart conversely will sport around 4TF, and according to marketing materials we've seen previously, it is being positioned as the most-affordable entry point to next-gen experiences.

It's important to note, however, that TF doesn't really tell the entire story of next-gen systems, owing to piles of custom tech Microsoft is planning to bake into these consoles. For example, Microsoft already spoke about how ray-tracing will be a factor in next-gen systems, and while Lockhart has less raw power than the X, it will have capabilities that elevate it further than the X in various ways."

So Thurots  believes it's 12 teraflop which is equal to RTX 2080 super  and more powerful than baseline RTX 2080 at10 Teraflop.
