GeForce GTX 860M vs Radeon HD 7750

Intro

The GeForce GTX 860M has clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1152 SPUs along with 96 Texture Address Units and 16 Rasterization Operator Units.

Compare those specs to the Radeon HD 7750, which makes use of a 28 nm design. AMD has clocked the core speed at 800 MHz. The GDDR5 RAM is set to run at a speed of 1125 MHz on this card. It features 512 SPUs along with 32 Texture Address Units 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 is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
