GeForce 9800 GT 1GB vs GeForce 9800 GTX+
Intro
The GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this specific model. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.Compare all of that to the GeForce 9800 GTX+, which makes use of a 55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 RAM works at a frequency of 1100 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
