GeForce GTX 460 SE vs Radeon HD 6670 (OEM)

Intro

The GeForce GTX 460 SE makes use of a 40 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR5 memory is set to run at a speed of 850 MHz on this particular card. It features 288 SPUs as well as 48 Texture Address Units and 32 Rasterization Operator Units.

Compare all of that to the Radeon HD 6670 (OEM), which features a core clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 applied per second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
