GeForce GTX 860M vs Radeon HD 5750 1GB

Intro

The GeForce GTX 860M makes use of a 28 nm design. nVidia has clocked the core speed at 797 MHz. The GDDR5 memory is set to run at a frequency of 1000 MHz on this specific card. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Compare all of that to the Radeon HD 5750 1GB, which features a core clock frequency of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also features a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 720(144x5) SPUs, 36 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
