GeForce 9500 GT 512MB GDDR3 vs Radeon HD 4670 512MB

Intro

The GeForce 9500 GT 512MB GDDR3 has core speeds of 550 MHz on the GPU, and 800 MHz on the 512 MB of GDDR3 RAM. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.

Compare all that to the Radeon HD 4670 512MB, which uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory works at a frequency of 1000 MHz on this specific card. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher 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 amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
