GeForce 9500 GT DDR2 vs Radeon HD 5450

Intro

The GeForce 9500 GT DDR2 features core clock speeds of 550 MHz on the GPU, and 500 MHz on the 256 MB of DDR2 memory. It features 32 SPUs as well as 16 Texture Address Units and 8 ROPs.

Compare those specifications to the Radeon HD 5450, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 memory running at 800 MHz through a 64-bit bus. It also is comprised of 80(16x5) SPUs, 8 TAUs, and 4 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.

ofcourse shubh is right. ive tested both of em in my pc.
what i found is 9500 is 70% better than 5450

Snowman says:

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.
