My MSI FX5900 Ultra (2.2ns) runs evey thing just fine and i ran that card for the last two years o/c @510MHz core/930MHz ram and i never had any problems with any programs or games at 1024x768 @85Hz with 2xaa/8xan. this is the fastest 4-pipe around next too FX5950 Ultra.

I getting a spring upgrade to the G71 (7900 Ultra). I thing this is going to be a big jump for me!


Oh, it will be.

I noticed a tremendous performance increase when I got my 6800GT. So you'll notice even more with a 7800GTX/Ultra.

And the 5950U was NOT a bad card. The only game MY 5950U actually struggled with (aside from FEAR) was FarCry, but that was cause I had AA/AF all the way up and vsync enabled. Even the 9800Pro/XT would start lagging with those settings. But alas, the 5950U DID have problems with shaders, it WASN'T the most efficient card of all time. But it was far from a poor performer.

:rofl:
No it wasnt/isnt this bad.
From what i think, it was Valve for HL2 responsible for this reputation of FX59xx. I remember the Official Leaked benchies of Hl2, where the 9800 had 90 fps and fx5900 had 40.

AFAIK the FX59XX series defaults to DX8 in HL2 cause of low performance.I also remember some TRAOD tests were it also sucked but I'm too lazy to search for them.
Anyway who cares, that series is dead and better things have come our way.(xmasgrin) (cheers)

Half Life 2 was sold to ATI, a simple fact. It would have ran fine had Valve offered a mixed mode support for FX59** series. FARCRY offered mixed mode and there wasn't any image or speed degredation.

Just imagine where would ATI be with their last generation of cards (X800 vs 6800) had games supported Shader 3.0!! Atleast FX59** was a Directx 9 compatible card and needed games to be coded in mixed mode, ATIs last generation couldn't even do that for shader 3.0.

N.B didn't mean to hi-jack the thread.

I had 5900 Ultra 2 years ago, it ran Half Life 2 fine with all options maxed 1024x768 8xAF at 25fps average to 50fps maximum with forced DX9. It not that slow or slideshow, it acceptance speed when Radeon 9800 Pro was the fastest at 100fps. (xmastong)

Let's talk about G71 speculation here please folks

[KillerX]

I just wanted to buy a 7800 GTX 512 Meg Card. But now after reading about upcoming hardware like G71 and AMD's 533 Mobo Platforms, I have my doubts. I suppose its always like that, there will always be that new and improved upcoming hardware release that will blow everything else away.

If you always wait for the latest and greatest, you will never upgrade! There will always be something a little better just around the corner. Atleast SLI technology provides you with a good upgrade path for the future. You can always slap a 2nd GFX card in your machine, and double your performance (These days its all about graphics card power - Focus has def. shifted away from CPU's)

I reckon a card as powerful as the 7800GTX 512 should let you run any games at decent qual for atleast the next year and a half.

Keep to the topic people thanks

Whatever specs the G80 supports I want it now !!!!

[Monnie Rock]

What is the difference in the G-71,G-72, and G-73 ?

[coldpower27]

What is the difference in the G-71,G-72, and G-73 ?

From what I can gather:

G71
32 Pixel Shaders
10 Vertex Shaders?
256Bit Memory Interface

G73?
Better be clocked at like 750+ MHz :S if it's anything like G73M.

G73M
450 MHZ
1 GHZ Memory
8 Pixel Shaders
5 Vertex Shaders
128 Bit Memory Interface

G72?

G72M
450 MHZ
900 MHZ Memory
4 Pixel Shaders
3 Vertex Shaders
64Bit Memory Interface

shaders and pixel processing pipelines are different. Each pixel pipeline can have a combination or pixel proccessign units mini or fulll or whatever combination, it is not so clear cut as all IVHs have differnt ways of implementing this.

g71 is essentially a 8 quad GPU ie with 32 pixel processing pipelines not 32 shaders!

Indeed .. i believe the G71 might end up with 64 fragment (MADD) shaders if we assume 2 ALUs per pipe.
thats of course when ignoring the specialised ALUs in the pixel shaders like dynamic branching and fog units.

Pixel shader term is ok but I think it's a bit confusing....

NVIDIA's official term for "pixel shader" is fragment processor or fragment pipeline. Probably the most common "open" term is still pixel pipeline :)

The G70 fragment processor has two fp32 shader units (1 & 2) per pipeline, and fragments are routed through both shader units and the branch processor before recirculating through the entire pipeline to execute the next series of instructions. Both shader units has a full MADD ALU, mini-ALU (bias/scale, floating-point capable) and SFU (special function unit for nrm, sin, cos, rcp etc. instructions).

The branch processor and fog ALU (fixed unit) are part of the fragment processor. The texture memory unit (TMU) is called as texture processor or texel pipeline (L1/L2 (shared with vertex texture fetch)/DRAM). The texture processor is in-build into shader unit 1.

If G71 has 32 fragment or pixel pipelines then it has 32 fragment processors and 64 shader units (64 full MADD ALUs, 64 mini-ALUs and 64 SFUs). G71 can do 64 four-wide fp32 vector MADs per clock cycle in the fragment processor, plus 32 texture lookups per clock cycle.

The MADDs per clock cycle (pcc) performance (pixel shader) estimation:

NV40 425 MHz = 16 MADDs pcc = 6.80 GFLOPs
G70 430 MHz = 48 MADDs pcc = 20.64 GFLOPs
G70 550 MHz = 48 MADDs pcc = 26.40 GFLOPs
G70 625 MHz = 48 MADDs pcc = 30.00 GFLOPs
G71 430 MHz = 64 MADDs pcc = 27.52 GFLOPs
G71 550 MHz = 64 MADDs pcc = 35.20 GFLOPs
G71 625 MHz = 64 MADDs pcc = 40.00 GFLOPs
G71 650 MHz = 64 MADDs pcc = 41.60 GFLOPs
G71 700 MHz = 64 MADDs pcc = 44.80 GFLOPs

R420 525 MHz = 16 MADDs pcc = 8.40 GFLOPs
R480 540 MHz = 16 MADDs pcc = 8.64 GFLOPs
R520 500 MHz = 16 MADDs pcc = 8.00 GFLOPs
R520 625 MHz = 16 MADDs pcc = 10.00 GFLOPs
R580 500 MHz = 48 MADDs pcc = 24.00 GFLOPs
R580 625 MHz = 48 MADDs pcc = 30.00 GFLOPs
R580 650 MHz = 48 MADDs pcc = 31.20 GFLOPs
R580 700 MHz = 48 MADDs pcc = 33.60 GFLOPs
