GeForce GT 440 1.5GB vs Radeon HD 5670

Intro

The GeForce GT 440 1.5GB features a GPU core clock speed of 594 MHz, and the 1536 MB of GDDR3 memory is set to run at 900 MHz through a 192-bit bus. It also is made up of 144 Stream Processors, 24 TAUs, and 24 Raster Operation Units.

Compare that to the Radeon HD 5670, which comes with a GPU core clock speed of 775 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 400(80x5) Stream Processors, 20 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends 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.

pues vemos que se esta comparando una 440 ddr3 , si fuera una 440 ddr5 quiza superara a la 5670

Hi says:

The chart 4 GT 440 is WRONG..
Its 128 bit nt 192 bit..
Texel Rate and pixel rate are also wrong so plz correct them..
And plz add benchmarks for gt 440...

Anonymous says:

actually gt 440 has 810mhz of core speed
