GeForce GTS 150 vs Radeon HD 3690/3830

Intro

The GeForce GTS 150 makes use of a 55 nm design. nVidia has clocked the core speed at 740 MHz. The GDDR3 RAM works at a speed of 500 MHz on this particular card. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare that to the Radeon HD 3690/3830, which has GPU clock speed of 668 MHz, and 256 MB of GDDR3 memory running at 828 MHz through a 128-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 TAUs, and 16 ROPs.

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

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount 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 a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
