GeForce GTS 250 1GB vs Radeon HD 5450


Intro

The GeForce GTS 250 1GB has a core clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also uses a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare those specs to the Radeon HD 5450, which has GPU clock speed of 650 MHz, and 512 MB of DDR3 RAM set to run at 800 MHz through a 64-bit bus. It also is made up of 80(16x5) Stream Processors, 8 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
