GeForce GTX 285 1GB vs GeForce GTX 660
Intro
The GeForce GTX 285 1GB features a clock frequency of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also uses a 512-bit memory bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 Texture Address Units, and 32 ROPs.Compare that to the GeForce GTX 660, which features GPU core speed of 980 MHz, and 2048 MB of GDDR5 RAM running at 1502 MHz through a 192-bit bus. It also is comprised of 960 Stream Processors, 80 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units by the core 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 per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.

One Response to “GeForce GTX 285 1GB vs GeForce GTX 660”If you're going for a 285 get the 2GB version... I would personally recommend an r9 280x though.
