And how much did nVidia pay Activison/id for the Doom 3 deal?
I've
heard
4-5 million. Gwarsch! Carmack has sold out to nVidia!! He's deh
devil!!

He also seems to be in bed with Intel. His engines always run
better on nonAMD systems.


That's because AMD sucks ass.





I'll take SSE2 over 3DNOW! any day....


I mean, come on people... give it up... 3dNow's optimizations are now
INCLUDED on most GPU's.


3dNow only aided older cards that didn't have the bandwidth to match
the processor.


Now, the GPU's are outperforming the CPU, so it's entirely unnecessary.



AMD should definitely update this instruction set... if they did they'd
be god.

Imagine a processor with Pixel Shader 3.0, bump mapping, vertex
shading... drool


Um, you do know the Athlon64 supports SSE2, right?

Carmack announced:
"As DOOM 3 development winds to a close, my work has turned to
development of the next generation rendering technology. The NV40 is
my platform of choice due to its support of very long fragment
programs, generalized floating point blending and filtering, and the
extremely high performance," said John Carmack, president and
technical director of id Software

When Carmack speaketh, the world stands still and the games will stutter.

He also seems to be in bed with Intel. His engines always run better on
nonAMD systems.

Because SSE is mysteriously disabled in Q3 engined games when run on
AMD CPU's.

Exactly. To be fair, the SSE-enabled AthlonXP did not exist when Q3 was
first programmed, and you can't blame Carmack for not wishing to revisit old
code.

There's a good chance he used a no doubt convenient Intel compiler
instruction that tests for the presence of an Intel cpu, rather than
actually test for SSE itself.

So, better start saving now for the 6800U ??? And power-supply.
Might as well just get a new case and power supply of the style
with the fan (hopefully quiet) in the middle of the cover and
close to the 6800U.........

John Lewis

Before the R420 previews are even out? Nope.

ATI has been rather quiet so far but I will hold onto my $ till they have
spoken. May the best card win...

From the nVidia news release:-
--------------------------------------------------------------------------
--------------------------------------
NVIDIA Corporation ( NASDAQ: NVDA), the worldwide leader in visual
processing solutions, introduced today the NVIDIA(R) GeForce(TM) 6800
models of graphics processing units (GPUs) for high-performance
desktop computers. The NVIDIA GeForce 6 Series, which includes the
flagship GeForce 6800 Ultra and GeForce 6800, is designed to deliver:

-- Industry-leading 3D performance -- new superscalar 16-pipe
architecture delivers more than twice that of current industry leading
NVIDIA GPUs

-- New features, including Microsoft DirectX(R) 9.0 Shader Model 3.0
feature set -- for ultra-realistic cinematic effects

-- Unprecedented on-chip video processing engine -- enabling high-
definition video and DVD playback

"This is the biggest generation-to-generation performance leap that we
have ever seen with a new GPU," said Jen-Hsun Huang, president and CEO
of NVIDIA. "In addition to the raw performance increase, we had two
fundamental strategies with the 6800 models. First was to take
programmability to the next level with the industry's only GPU with
Shader Model 3.0. Second was to extend the reach of GPUs to the
consumer electronics market with a powerful and fully programmable
video processor capable of multiple video formats and 'prosumer' level
image processing."

"As DOOM 3 development winds to a close, my work has turned to
development of the next generation rendering technology. The NV40 is
my platform of choice due to its support of very long fragment
programs, generalized floating point blending and filtering, and the
extremely high performance," said John Carmack, president and
technical director of id Software
--------------------------------------------------------------------------

Still have to hear from Gabe@Valve. All quiet from him, so
far......... Must be busy tweaking the HL2 code for Shaders 3.0 ?
Shaders 2.0 must now be just a little passe..... Far Cry V1.1
implementation of Shader 3.0 is apparently little rough at the
moment, but Crytek says that they are working on it. No doubt
it will be in a polished patch by the time the NV40 is retail
available.

For me personally the 6800 is as exciting a step forward in PC
peripherals as the Voodoo1 was when it first emerged. Not only for
the 6800s enormous graphical power, but also for its potential
contribution to PC-based video production and editing, which is an
active business for me. The very powerful integrated video processor
is as important to me as the graphics capability, particularly the
MPEG-2 encoding hardware elements. Adobe After Effects have
already declared support for the NV40 and no doubt other video
toolmakers like Pinnacle are looking hard at its capability. Now if
Intel would only reduce the price of the P4 EE to that of the retail
list of the 6800Ultra, or less, instead of fleecing potential
customers at $999 a pop, then I would be very happy indeed with my
video production/editing hardware after those two were installed.

SSE2 is 2nd generation SIMD instructions, 3DNow is first generation
and were the first FP SIMD instructions ever used on a CPU. You're
comparing old and new.

Besides, all AMD64 CPUs support SSE2 anyway.

Here is another John Carmack quote:

I don't care what Carmack or Sweeny say about video cards folks...
they are in bed together.. so its invalid. I'll let the specs and head
to head reviews make my decisions for me thank you. Use your heads
guys..

Actually I was rather amused to see the preview at HardOCP
(http://www.hardocp.com/article.html?art=NjA2). The performance is
now-where near where I expected. 10-15 fps better then the ATI 9800 XT
is a joke. Of course I expect the 3rd party companies to juice up the
card a bit. We'll see.. but my money is on ATI for retaining the crown
this next generation.

If you noticed
the 5950 beat the 9800 on most of the benchmarks also and the 6800 killed the
9800 on a lot of the games.

Yes, but note how HardOCP test - with different settings for different cards
for many of the tests.

Look here for a case of a doubling of performance:
