GeForce GTX 950M vs Radeon HD 6450 (OEM) 1GB

Intro

The GeForce GTX 950M makes use of a 28 nm design. nVidia has clocked the core frequency at 914 MHz. The DDR3 RAM works at a speed of 1000 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

Compare those specs to the Radeon HD 6450 (OEM) 1GB, which comes with a core clock speed of 750 MHz and a GDDR5 memory speed of 900 MHz. It also features a 64-bit bus, and makes use of a 40 nm design. It is made up of 160 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics 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 maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
