GeForce GTS 250 1GB vs Radeon R7 250

Intro

The GeForce GTS 250 1GB features a clock frequency of 738 MHz and a GDDR3 memory speed of 1100 MHz. It also features a 256-bit memory bus, and uses a 65/55 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon R7 250, which comes with clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
