GeForce GTS 150 vs Radeon HD 6570 (OEM) 1GB

Intro

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

Compare those specifications to the Radeon HD 6570 (OEM) 1GB, which has a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
