Geforce GTX 670 vs Radeon R9 M290X

Intro

The Geforce GTX 670 features a core clock frequency of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also features a 256-bit memory bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Compare all of that to the Radeon R9 M290X, which makes use of a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory works at a frequency of 1200 MHz on this particular card. It features 1280 SPUs along with 80 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
