GeForce GTX 280 vs Radeon R9 M290X

Intro

The GeForce GTX 280 uses a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 RAM works at a frequency of 1107 MHz on this particular model. It features 240 SPUs along with 80 TAUs and 32 Rasterization Operator Units.

Compare that 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 works at a frequency of 1200 MHz on this specific card. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock 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 applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
