GeForce GTS 250 512MB vs Radeon R9 M385X

Intro

The GeForce GTS 250 512MB makes use of a 65/55 nm design. nVidia has clocked the core speed at 738 MHz. The GDDR3 memory is set to run at a frequency of 1100 MHz on this card. It features 128 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M385X, which uses a 28 nm design. AMD has clocked the core frequency at 1100 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this particular card. It features 896 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
