GeForce 9800 GTX vs Radeon R7 250

Intro

The GeForce 9800 GTX uses a 65 nm design. nVidia has set the core frequency at 675 MHz. The GDDR3 RAM works at a speed of 1100 MHz on this particular card. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R7 250, which features GPU core speed of 1000 MHz, and 1024 MB of GDDR5 RAM running at 1150 MHz through a 128-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
