Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount 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 processed in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to 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.
