Polish Parhelia confirmation

Hang on...

You are now going on about a single core with multiple memory bus. (dual bus).

The first PII and PIII cartridges had one core, and some really fast cache memory on them.
That cache memory eventually ended up being included in the core itself.

Multi-core or Multi-bus is asking for more traces, and more and more complex boards, hence a big hike in price.

...and why should one die die?

isn´t the g450mms a multi-chip vga btw?

One die could die in the manufacture process. If all dies are needed to function correctly you can throw the entire chip into the bin. If for example you employee an -independent- dual-bus with two different memory chips then you can still sell it as a half-baked solution.

IMHO:
A bit like GeForce4MX which is a GeForce4 Ti with broken programmable T&L and possibly one or two broken Pixel pipelines. Just cut a few traces to open the bypass.... and you're done.

So instead of selling a Ti for 300$ you can sell a broken (MX) chip for 150$

Except this is done on-chip and not on separate dies.

You would think that the same can be done with multiple cores...

Be patient.... even the light itself takes more than 8 minutes from the sun to shine on us.

TDB,
The MMS video cards are two/four independent video systems, each running their own display. They aren't working together

The MS and Intels are two/four independent companies, each running their own business. They aren't working together...

Sorry, just couldn't keep my mouth shut...

So how hard would it be to hijack a horizontal retrace and start outputting some other memory region (even output other chip's z-buffo)? If this could be tuned, then.. A card could (theoretically) share tex memory and chip should have it's own z-buffer, but only for a limited screen space (1280x512 instead of 1024x1024). And then you could have hw multiplayer (a la Ps1 games) a bit easier, also horsepower enhacement by just dumping more chips on PCB .

Well. I guess it would already be done if it was viable. I don't exa ctly remember what 3dfx SLI did, wasn't it that they rendered every other scanline?

umm... NV17 is based on NV15/NV10 core and NV25 is based on NV20 core so GF4MX isn't broken GF4Ti... they are different chips. even John Carmack said that naming them like they are named sucks.

So nVidia just picked their old GF2GTS and add some features (DVD decoding, nView, GF3 style memory controller.), re-spinned it to smaller line and slapped a new name to it. And Voila! we got GF4MX that isn't GF4Ti Compactible, but more like an new mainstream DX7 chip.

they made it to compete against Radeon 7500 over a half a year later after Radeon 7500 was introduced. And I think this is the only reason why ATI hasn't released RV250 chip yet. There hasn't been any reason for it.

Maybe GF4Ti4200 release will make Ati to launch RV250. Or then they are just renaming it to RV300 and it will be released as Mainstream DX8.1 chip simultaneusly when ATI releases R300 as High End DX9 chip.

jwb, I sure glad your not an EE and only speculating

We know, but we'd really, <I>really</I> appreciate it if you would - at least until you can start making sense and not spouting erronous ****.

See, this is excactly what I mean. I'm in that forum because of fantasy, hopes, etc...

But you sound like I'm a complete idiot and your tha man which keeps erveryone well informed except me.

If you know more then your crystal ball is washed out and dirty and actually havn't lost anything in this forum. Got me?

BTW This is not meant as a personal offense.

Yes you are right... in the sense that this is the "offical" version.
