GeForce GTX 285 1GB vs Radeon R9 380 4G

Intro

The GeForce GTX 285 1GB has a clock frequency of 648 MHz and a GDDR3 memory frequency of 1242 MHz. It also makes use of a 512-bit bus, and uses a 55 nm design. It is comprised of 240 SPUs, 80 Texture Address Units, and 32 ROPs.

Compare those specifications to the Radeon R9 380 4G, which has core speeds of 970 MHz on the GPU, and 1425 MHz on the 4096 MB of GDDR5 memory. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends 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.
