One thing that NVIDIA has been keen on with their video cards of the last couple of years is the re-use of the same chip for different SKUs. This has the advantage of higher utilization of chips as you can use a bad GeForce 9800GTX with SPs disabled as a GeForce 9800GT. This has an inherent disadvantage in that if the chip is poorly designed as was the case with the G86 all of the chips designed could have issues.

The GeForce 9800GT uses a modified version of the G92 chip that was first introduced with the GeForce 8800GT cards last year. This chip has 112 SPs, 16 ROPs and was highly successful. NVIDIA uses the codename G92b for the 9800GT chip. They say they will move this chip to the 55 nanometer process in the near future with this chip.

I won’t get into the politics of DirectX 10.0 versus DirectX 10.1 in this review. ATI cards were the first to hit the market with support for this graphics API and S3 has followed suit. NVIDIA says with some justification that it is a minor update and the DirectX 10.0 hardware on their video cards is capable of running some of the features of 10.1, but compliance requires full feature support.

Palit has clocked their GeForce 9800GT card to the reference 9800GT clock speeds NVIDIA recommends with these cards of 600MHz for the core, 1.8GHz for the memory (effective) and 1.5GHz for the Shader clocks. The Palit 9800GT Super+ 1GB card has a memory bandwidth of 57.6GB/second and 1GB of Framebuffer memory. The Pixel fillrate is 9.6 Gigapixels/second and the texture fill rate is 38.4 Gigatexels/second.

One of NVIDIA’s big pushes is the support for CUDA, their computing for graphics cards initiative and the PhysX game physics engine. NVIDIA bought Ageia a few months ago and has now integrated the drivers into a PhysX driver package. Due to the fact that ATI cards currently do not support PhysX natively, all tests were run with PhysX disabled.

One change to the chip is the addition of Hybrid Power and support to the 9800GT card which is not present on the 8800GT card. HybridPower allows the motherboard to turn off the discrete graphics card when in idle mode or 2D mode, saving energy. With the big push of the Green initiative, the video card manufacturers are pushing energy-saving technologies onto every card they sell.

Here’s a chart of the current NVIDIA and ATI lineup with the lowest prices for each card on Note the overlap of the various cards and pricing due to the competitive nature of the industry. The Palit GeForce 9800GT Super+ 1GB card is available for $170, a small premium over the pricing of the 9800GT and 15% less expensive than the 9800GTX.
