GeForce 8300 GS (OEM) vs Geforce GTX 770

Intro

Compare all of that to the Geforce GTX 770, which comes with GPU core speed of 1046 MHz, and 2048 MB of GDDR5 RAM set to run at 1753 MHz through a 256-bit bus. It also is made up of 1536 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
