ZX NEXT Vs. who MSX ???

It's complicated to compare a machine designed in 2017 with MSX from the 80s.
The ZX Spectrum Next is a strange hybrid between elements that bring it closer to 8-bit computers and others that seem quite anachronistic to me.
Having said that, I have the impression that an MSX Turbo-R with a V9990 card could run most of the games designed for ZX Spectrum Next.

Personally, I’m not at all interested in a ZX Spectrum Next type “enhanced” feature set.

For MSX I have a connection to it and like to work within the constraints that it has. You can choose MSX1 for some tough constraints but also simplicity, MSX2 for colourful graphics or boosted pattern mode power, MSX2+ for scrolling power, and turboR for something that really needs CPU power. Even the Graphics9000 already feels like a cheat to me tbh, but if there’s something I really wanted to do that the base systems couldn’t, I would use it.

But then to use a system with a new feature set based on today’s technology which were just a selection dreamed up by some random person or group of persons, I do not understand the connection with our retro system, it seems like a strange extension of capabilities while still imposing unnecessary artificial limitations because you work within an existing architecture, but it’s not really a part of the legacy. At that point I might as well develop for a different existing widespread platform at that point, and gain more enjoyment and user base from it.

For ZX Spectrum, for me the system is characterised by the attribute clash graphics and the bitmap-based games. It is awesome to see what people can achieve with it, e.g. in terms of beautiful graphics or huge software sprites like Travel Through Time. If you expand it so far beyond that, I think it loses what makes a Spectrum a Spectrum. Why not just develop for GBA or Android or something.

My 2 cents also for 1ChipMSX / Zemmix, since both of them (1Chip and Next) are FPGAs, so they can be compared.

But the ZX Spectrum Next has new graphics modes and a _lot_ more memory. On top of that it has new Z80 commands apparently. So just because it is a FPGA doesn't mean we can compare it to a 1ChipMSX.

As other people have stated before, this is a very difficult comparison because the the ZX Spectrum Next is build using current day technologies and insights.

Roughly speaking it might be 'comparable' with a TurboR machine?
(TurboR has additional memory, R800 CPU is Z80 compatible but with more commands and faster).

I don't think there needs to be comparison between the Next and the MSX range.

The Next is on the one hand, an updated Spectrum, and in those cases the later editions of the MSX can do similar things.

If we're talking about the Raspberry Pi in the some of the Next's, then it's more comparable to a modern Linux setup, and then you really shouldn't compare that with an MSX.

Keep in mind that the Spectrum never had hardware sprites nor hardware scrolling, therefore the Next is a step forward from the Spectrum 128K (or +3). But the MSX has hardware sprites from the beginning so it's really not comparable.

I would likely not develop any games specially for the Next, but then again I already made games for the Spectrum and they are obviously working on the Next. I might change my mind if I get a physical Next, but no for now.

(I also think it's hard to make something that's really Next only, since they have to look a lot better and has to have more content than 128K.)
