GeForce 9500 GT DDR2 vs Radeon HD 5450
Intro
The GeForce 9500 GT DDR2 comes with a GPU core speed of 550 MHz, and the 256 MB of DDR2 memory is set to run at 500 MHz through a 128-bit bus. It also is comprised of 32 SPUs, 16 Texture Address Units, and 8 ROPs.Compare that to the Radeon HD 5450, which comes with core clock speeds of 650 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 80(16x5) SPUs as well as 8 TAUs and 4 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.

4 Responses to “GeForce 9500 GT DDR2 vs Radeon HD 5450”geforce 9500 gt is better than hd 5450. go for 9500 gt
ATI RADEON BEM MELHOR AGUENTA BELO OVERCLOCK RODEI CALL OF DUTY MW3 TUDO HIGH+EXTRA COM RESOLUÇAO DE 1280X720 30 FPS DE BOA COM OVERCLOCK DE 700 MHZ GPU E MEMORIA 531 MHZ DDR2 !!!!
ofcourse shubh is right. ive tested both of em in my pc.
what i found is 9500 is 70% better than 5450
In a machine with only PCI slots, these two were the top dogs for a long time. The GT520/610 cards that Zotac released in PCI after these two have only managed to knock off the HD5450 for the number two spot. 9500GT is still faster. It might be another generation or two, if ever, before someone releases a PCI card with both more features and more speed than 9500GT.
