Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.

One Response to “GeForce GTS 250 512MB vs GeForce GTS 450 1GB”i have a hd4770 with a self build reasonable spec pc on benchmark06 it has a score of 11285 compared to my 8600 score off 3640 and my hd4650 score of 4750 from but i still get frame gerking playing burnout paradise.its not so bad in windows xp but windows 7 it not so good.even worse when nero 10 is installed.i`ve never been a big fan off ati cards and i got this hd4770 cheap for around £50.graphic quility is a big thing for me but i have a small budget.i`ve always gone for nvidia so i`m considering a gts250 or gts450 oc version .i still might get gerking but ive found nvidia are better in some ways and even though I`m impressed with the hd4770 but i think i`ll stick with nvidia. thanks hwcompare helped me.
