GeForce GTS 250 512MB vs GeForce GTS 450 1GB
Intro
The GeForce GTS 250 512MB features a core clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also makes use of a 256-bit bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the GeForce GTS 450 1GB, which comes with clock speeds of 783 MHz on the GPU, and 902 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs along with 32 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out 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 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 number of pixels the graphics card 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 Raster Operations Pipelines 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

Comments
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.
