GeForce GTX 960M vs Radeon HD 3850 256MB

Intro

The GeForce GTX 960M uses a 28 nm design. nVidia has set the core speed at 1096 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Compare those specs to the Radeon HD 3850 256MB, which makes use of a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 memory is set to run at a speed of 828 MHz on this particular card. It features 320(64x5) SPUs along with 16 TAUs and 16 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 once 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher 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 that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
