GeForce GTX 285 1GB vs Radeon R9 M395X

Intro

The GeForce GTX 285 1GB uses a 55 nm design. nVidia has clocked the core frequency at 648 MHz. The GDDR3 RAM works at a speed of 1242 MHz on this card. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M395X, which uses a 28 nm design. AMD has set the core speed at 723 MHz. The GDDR5 memory works at a frequency of 1250 MHz on this specific model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 number of pixels that the graphics chip can possibly record to the 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 speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
