GeForce GTX 285 2GB vs Radeon R9 M290X

Intro

The GeForce GTX 285 2GB comes with clock speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 RAM. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M290X, which makes use of a 28 nm design. AMD has clocked the core frequency at 850 MHz. The GDDR5 memory is set to run at a speed of 1200 MHz on this card. It features 1280 SPUs along with 80 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
