Wow! Now I know I'm getting one! 2Kg makes it the heavyweight

4.4 pounds, eh? I can see that one... I just hope that Sega included a
fan in their system... RISC processors are notorious for running hot,
and they seemed to have packed this thing pretty tightly... PVRNG,
modem, processor(s), 16mb (main) ram, 64-bit sound chip, controller
interface... etc. I do wonder how much video ram is in there... in
order to produce the numbers they are talking about, at 640x480
interlaced - NTSC is interlaced by standard, then they would need at
least 4-6 just to start off with... then with WinCE2.0 (special tuned
version, mind you) they would have to have probably more... or is the
memory unified... hope not.

personally I think it should have been shaped like the console in my
dream a couple of months ago. At least it is not black, since there is
the theory that all black consoles fail (I still see the Genesis as the
exception to this one). Unified memory is not bad if it is well
designed.

Wasn't an extra 10 MB (or so) of RAM added specifically for the WinCE
operating system, on top of the 16MB already there?

No comment on the rest, but RISC processors known for running hot? Where
did you come up with this one? The exact opposite is almost always the
case.

8 was added, although whether or not that was for OS overhead is
up for speculation. Initially, I thought it was, but other sources have
informed me that CE is VERY low overhead and shouldn't take up more than
4, at WORST, when the developer decides to use DirectX. The rest of the time
it will be even less. There is 26 Megs total, divided thusly: 16 Megs main
RAM, 8 texture RAM, and 2 sound RAM.

64 Megabits is 8 Megabytes, not 16.

Who came up with that goofy theory? The 2600 was a success and it was
black. So was the Genesis and ColecoVision. The Lynx & Game Gear were
black, they were both mild successes. The SMS did well in Europe and the
TG-16 (PCE) did well in Japan.
OTOH, the Odyssey was white - bombed big time. Odyssey2 was silver.
Studio II was, uh, off white.
So, what was that silly theory again?

This is a pretty stupid discussion to have on rgvs, but what the hell ;).
The only major CISC chip to compare to is the Pentium or PII and those run
much hotter than any mainstream RISC chip.
The reason is that the RISC chips contain fewer transistors and take less
power to run (and so generate less heat) than a CISC procesor.

Man, what is the world coming to, when we can sit and calmly say that an
operating system gobbling up 4 megabytes of RAM space is LOW overhead?

I dont know, but if you follow it after NES, it works with fair
accuracy.

If you start it after the NES like I would, the Genesis is the only
true major hit.

The theory is black consoles fail, I apply it to the NES and onward (I
consider the crash in 83 an interruption and dont count the stuff
before it, but that is only my opinion), I dont know what the original
inventor of this theory is but I did not say white or gray consoles
succeed, I simply said the black ones tend to fail (at least to capture
the market) in most cases. There is a trend in it, but I agree it is
not the best theory.

Actually I came up with the theory. Its White systems always beat out
black systems. The side effect is almost all black systems fail too =)
Plus its a goofy theory that's for fun, not to be taken very seriously.
Its just funny that it fits. I remember when I saw the N64 and said, oh
shit and thought of the theory. Turns out to have been true =)
NES/Famicom - Light Grey = #1
SNES/SFC - Light Grey = #1
Nintendo 64 - Black = Flopping in Japan, distant 2nd in Europe, 2nd in
the US
Take it as you will =)

Well, I guess the world is dumping 2D for good... Without a dedicated
2D proccesor, won't DC suffer the same problems as the PS?
Or maybe Sega feels that the new CPU is so fast that a 2D
GPU is pointless... ?

This is an entirely groundless assertion. The amount of heat generated
by an IC is due to a number of physical factors. Instruction set design is
only suggestive of what that physical form might be. In the case of an
Alpha the sole imperative was performance and the system engineers could put
it in a refrigerator if necessary. (Check out the Kryo-Tech offerings
sometime.) The Alpha also sucks juice like crazy and consequently
dissipates a great deal of heat.
The SH-4 in the Dreamcast is the latest in a line whose primary target
has always been embedded systems, especially portable battery operated
devices like digital cameras. It is very power efficient, second only to
the StrongARM at this point. As a result heat will not be an issue with the
CPU. The PowerVR chips in this design are made using .25 micron fabrication
and also run reasonably cool for the performance delivered.

Unlike the previous generation of PowerVR chips the latest incorporate
2D so as to offer a single slot solution for PCs and a reduced part count
for embedded apps like Dreamcast.

No, CE should take up about 2MB or so - how much memory do Palm Pilots have?
<10MB currently I think - and they use CE. No doubt Sega made MS customize CE

CE is a pretty decent OS folks...it's 95/98/NT without the fat.

Palm Pilots use PalmOS, which is MB with built-in apps in its current
form. WinCE is probably bigger than that, given that it has more
fluff/frills, but the new WinCE machines start at something like 4MB,
so it can't be too big.
>CE is a pretty decent OS folks...it's 95/98/NT without the fat.
That's still relative. It all depends on how much it puts itself in
the way of the hardware. WinCE machines are slower compared to their
processor than Palm machines, for instance.

Agreed. Hopefully it's more like NT, less like 95/98...

Ahh! This is good to know!
Can you imagine the people's reaction when the
most hyped/anticipated 2D fighting games (CapVsMar and SFIII) show up
in DC, and it isn't arcade perfect becauseSEGA didn't incorp. good 2D hardware
in the console? (Kinda reminds you of the first Daytona USA on Saturn launch,
doesn't it? ) :P

According to Hitachi's own website, SH4 is a 64 bit RISC processor.
not 128 bit. True, Dreamcast has two of them, but that doesn't make
Dreamcast a 128 bit system. Just like Saturn is not a 64 bit system,
just because it has two SH1 32 bit CPU.

I don't think so, the most up to date chip from Hitachi in the SH family
is the SH4 (SH7750), it does 360 MIPS, just came out in April. This
is the same chip some of the Windows CE system will be using. Look
at the press release
http://www.halsp.hitachi.com/news/html/hitachi-microsoft.html.
The SH7750 is MOST CERTAINLY 64 bit, not 128 bit CPU.
look at the originally announcement of the SH7750
http://www.halsp.hitachi.com/news/html/pmh14pr001d1.html
it runs at 200 MHZ, and has 360 MIPS, 1.4G flops. Sounds like the same
chip to me. Which means DC is not 128 bit system.

That's pretty recent news. Game Busters also didn't mention that the
general purpose RAM was specced up to 16M (they quote 64 megabits -
8 Megabytes).
