Leadtek and Gainward cards; Specifications

Ad

The card models we tested are from Leadtek and Gainward. The Leadtek WinFast PX9600 GT Extreme uses the same design as the nVidia reference card. On the outside, nothing sets it apart from the GeForce 8800 GT V2 – that is, the version that was equipped with the new, larger cooling fan with the advantage of being quieter under load (a better air flow/noise ratio thanks to the significant reduction in rotation speed due to its size). It’s a single-slot card whose PCB is entirely covered by the cooling system housing, keeping hot air inside the case. Aside from the usual two connectors (PCI Express 6-pin power and SLI), there’s a 2-pin connector, and the reference card comes with a small cable for connecting the internal S/PDIF connector on the motherboard or sound card (via 2 pins) to the 9600 GT.

Nvidia Geforce 9600GT

As you may have gathered, this version also comes with an active DVI->HDMI adapter including audio. nVidia is implicitly recognizing the soundness of the initiative AMD ushered in with its Radeon 2000 – but without the same elegance, since, lacking an audio controller, the GeForce 9600 GT needs to be connected to an external controller via this cable, meaning that it loses the motherboard/sound card’s S/PDIF connector and system sounds (if you want to distinguish your Home Cinema/TV installation from your PC speakers).

The really good news about the 9600 GT, finally, is the presence of 512 MB of onboard memory, though 256 MB and 1 GB versions are probably in the works. The 256 MB on the GeForce 8800 GT 256 MB was that card’s real limiting factor (despite its lower frequency than the 8800 GT’s). The GeForces were handicapped by too little memory, starting at 1280*1024 + antialiasing and 1680*1050, even with PCI Express 2.0 (which our motherboard uses).

Despite the reference design, the Leadtek model justifies the "Extreme" in its name because of its factory overclocking, with the GPU clocked at 720 MHz (1750 MHz for the stream processors) compared to the reference 650 MHz (and 1625 MHz); the memory remains at 900 MHz. It’s tempting to draw the conclusion that all models will be able to be clocked to those frequencies… The Bliss 9600 GT Golden Sample from Gainward, however, has made the choice of taking up two slots, in order to provide a wider range of outputs – and very attractive ones at that; two DVI-Is as on the Leadtek, but also an HDMI, a DisplayPort, digital coaxial, and finally a grille to help vent some of the hot air out of the case! Gainward took advantage of the extra real estate to build in a dual-slot heat sink using two heatpipes and an axial fan (for a better speed/noise ratio) with a PWM connector. This card’s frequencies have also been boosted – to 700 MHz for the GPU and 1000 MHz for the memory. The extra cost compared to the basic version (also offered by Gainward) is 20 €, which, for once, seems pretty reasonable.

Nice analysis as always but does anyone every proof read this stuff. On
Page 17 it seems clear that the TH UK guys were sent it by the American site and they forgot to check all the links, hence the [link to your 8800GT 256MB article here] comment. Also a mix up on the first page saying the 8800GTX had 786 not 768 ram.

It seems to get worse and worse!

Seems like a very good card. Fewer shading units, but faster memory than the 8800 GT. That 256-bit memory interface really shines, although I would not personally be willing to use any 9600 GT with less than 512MB, certainly not if they switched from GDDR3 to something inferior. I would buy this card and at this price I think it fills the mid-range gap very nicely. Thanks Tom.

Don't forget that the driver it's a new one...
I had msi 8600gt oc and i see big diferrent between 163.75 and 169.25 forceware driver so maybe the 9600gt come closer to 8800gt and with little overclocking maybe it can pass it!!

Ok so what happened to the next Generation should be faster and more powerful than the previous... Good rule I thought...

This is not good news for us recent EVGA buyers waiting for the new 8800 GTX/Ultra GPU killer...

Bob, it's classed as a mid-range card, but is able to compete with 8xxx series high-end cards. With more shader units it would be faster. Sure you can make it faster, but the cost soon jumps. Considering the kind of card it can out-class I think it's a very good card for the money.

Overclock the shaders. That should bring the performance up somewhat.

Still, why didn't they badge it as the 8650 or something? This generation-jumping that ATi started with the 3850/3870 gets incredibly confusing after a while. I'd hate to know how the poor saps in retail are coping with it, particularly with the average client/gamer IQ.

Yeh,

If they had just started the 9xxx series with the G92 8800GT and 8800GTS then everyones lives would be simplier!!
