VS

GeForce 8300 GS (OEM) vs GeForce GTX 480

Intro

The GeForce 8300 GS (OEM) comes with a GPU clock speed of 450 MHz, and the 128 MB of DDR2 RAM runs at 400 MHz through a 64-bit bus. It also is comprised of 8 SPUs, 4 Texture Address Units, and 2 Raster Operation Units.

Compare all that to the GeForce GTX 480, which comes with a core clock speed of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also features a 384-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 60 TAUs, and 48 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
