GeForce GTS 250 1GB vs Radeon R9 380X

Intro

The GeForce GTS 250 1GB comes with core clock speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare those specs to the Radeon R9 380X, which makes use of a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 memory runs at a frequency of 1425 MHz on this model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
