GeForce GT 315 vs Radeon HD 6570 (OEM) 1GB

Intro

The GeForce GT 315 has a core clock speed of 625 MHz and a DDR3 memory frequency of 790 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 48 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.

Compare those specs to the Radeon HD 6570 (OEM) 1GB, which uses a 40 nm design. AMD has set the core speed at 650 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this particular card. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
