GeForce GT 240 GDDR5 vs GeForce GTS 450 1GB

Intro

The GeForce GT 240 GDDR5 has a clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 32 TAUs, and 8 ROPs.

Compare those specifications to the GeForce GTS 450 1GB, which makes use of a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 RAM works at a speed of 902 MHz on this card. It features 192 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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