Lets post what we think we know so far

[Spiritwalker]

nV40:

8x2 dynamically allocated pipelines
can act as 16x1 and 16x0 depending on the circumstances
has 3 or 4 vertex shader units 3.0 compliant
may use said vs units to help in non Z PS functions
PS3 compliant
core 500 memory 500-600ddr3


R420

12x1
core built using quads (4 of them for 16 actual pipelines)
cores are being binned with the functioning 16 pipe ones being held back
VS 3 compliant
PS2+ (much improved over the R3xx)
may function as 8x1 for 32bit DX9
high end core running 600 memory at 550-600ddr3


anyone else?

[zakelwe]

GDDR3 is up to 800Mhz / 1600MHz effective and I think it will need all that to be honest.

Which card? Or do you mean both?
Post what you think the specs will be. See who can come closest in 3 weeks :D

Lets try to keep this as a spec only thread for the fun of it

[Geforce4ti4200]

nv40 8x2 at 475/1200
r420 at 12x1 at 500/950, 600/1100 for the xt verson

[Fiver]

NV40 16x1/32x0 475/1200.

[GlowStick]

NV40 16x1 475/500(raw), Dual DVi, GDDR3, 256bit bus, PS3.0, 175M
R420 8x1 500/500(raw), 6 Vertex Shaders, 256bit bus, PS2.0+++, GDDR3, 160M

[bkswaney]

NV40 16x1 475/500(raw), Dual DVi, GDDR3, 256bit bus, PS3.0, 175M
R420 8x1 500/500(raw), 6 Vertex Shaders, 256bit bus, PS2.0+++, GDDR3, 160M



I'll go with Glowstick on this one. :)
I still think the NV40 is a 16 pipe
and the 420 is a 8pipe with 6 vertex sharders.

So now NV40 is real 16 pipe and R420 not even 12 pipe :bleh:

[Geforce4ti4200]

god theres so much misinfomation its funny! before there almost no info now I keep hearing different things. Let me just make it final:


fx6000 at 8x2 475/1200
9900 pro at 12x1 at 600/1100

[GlowStick]

Yes, i do belive that R420 is 8x1 and i am guessing on the 1 part, honestly the only thing i feel is wrong with my specs is the memory clock, but i really dont count that as a 'big' deal because they buy the memory from the same manufacutres and have access to the same memory, so i woudlnt be suprized if they boht use the same high end gddr3 memory.

And you know this how? Everything we know for "sure" differs from what you just wrote. Meaning, Baron etc. are saying that R420 will have faster memory than NV40 has.

[Geforce4ti4200]

Has barton seen this in person? almost everyone is saying ati's clocks will be lower but perform better

[lokeshray]

r420 12x1, core clock:475mhz;memory effective :1000mhz, no PS 3.0
(no truform or severely crippled truform)
why i am being so conservative is coz of the core and memory clock speeds on the radeon 9800 pro , radeon 9800 pro 256 MB, radeon 9600 pro and radeon 9800 xt.

ATI doesnt have the guts to aggressively clock memory and cores. NVIDIA is far more aggressive and competitive.

r423 , 16x1, core speed:480 mhz, memory effective:1000mhz, pci express.. NO PS 3.0
(no truform or severely crippled truform)

and ofcourse, the usual hyper Z x+++++, and other stuff

[jAkUp]

NV40 will have 2 molex connectors... and dual DVI

[Geforce4ti4200]

two molex connectors is gonna hurt em bad, especially if the 9900 pro has only one!

NV's conference notes on anti aliasing (http://download.nvidia.com/developer/presentations/GDC_2004/D3DTutorial_Sim.pdf)

I am no techies but several things hit em when skipping thru it, they talk of Centroid, RGMS and Dynamic AA. So if they are talking about it, does it mean nv40 will at the very least have RGMSAA?

[zakelwe]

nv40nu 8x2 425Mhz core 1200Mhz memory $399
nv40u 8x2 500Mhz core 1400Mhz memory $499
nv40 Gainward GS Ultra XP/2000 8x2 525Mhz core 1600Mhz memory $599 :D

r420 8x2 500Mhz core 1000Mhz memory $999 plus HL3 voucher

heh heh.

Regards

Andy

[Geforce4ti4200]

heh very funny but I doubt neither card will be over $700 anyway. also the r420 is most likley the better card, ati wins once again

[ninelven]

Here goes :) :
NV40 -
16x1/32x0, 475/500 core, 1200+ effective GDDR3
PS 3.0 support, VS 3.0 support
New AA method (still inferior to ATI's but much improved)
AF (slightly better IQ wise than R420, slightly slower too)
4 VSU's

R420 -
8x2 (disguised as an 8x1) 500+ core, 1600 effective GDDR3
Not quite VS 3.0 support (very close)
PS 2.0+ (not as much/significant improvement here)
New AA mode (should be very nice), Same AF
6 VSU's

At GDC nVidia normaly do not talk about things that they are not able to do.

What is your guess for nv40 and r420 configuration demirug ? :)

NV40: 16x1/32x0
R420: 12x1

But without clockrates and FPU confuguration this mean nothing at all.

[-=DVS=-]

You know while we speculate who will win , i sure hope someone will have a real 16 pipe card or at very least 12 , so we CUSTOMER will get a nice upgrade doesn't realy matter if its Nvidia or ATI at this point :bounce:

If this NV40 16x1 475/500(raw), Dual DVi, GDDR3, 256bit bus, PS3.0, 175M
R420 8x1 500/500(raw), 6 Vertex Shaders, 256bit bus, PS2.0+++, GDDR3, 160M
or
fx6000 at 8x2 475/1200
9900 pro at 12x1 at 600/1100
or
NV40 -
16x1/32x0, 475/500 core, 1200+ effective GDDR3
PS 3.0 support, VS 3.0 support
New AA method (still inferior to ATI's but much improved)
AF (slightly better IQ wise than R420, slightly slower too)
4 VSU's
R420 -
8x2 (disguised as an 8x1) 500+ core, 1600 effective GDDR3
Not quite VS 3.0 support (very close)
PS 2.0+ (not as much/significant improvement here)
New AA mode (should be very nice), Same AF
6 VSU's


Are true all good for us except one below would be realy bad :eek2:

nv40nu 8x2 425Mhz core 1200Mhz memory $399
nv40u 8x2 500Mhz core 1400Mhz memory $499
nv40 Gainward GS Ultra XP/2000 8x2 525Mhz core 1600Mhz memory $599

r420 8x2 500Mhz core 1000Mhz memory $999 plus HL3 voucher
