GeForce 9400 GT 256MB vs GeForce GTX 870M

Intro

The GeForce 9400 GT 256MB uses a 65 nm design. nVidia has set the core frequency at 550 MHz. The GDDR2 memory is set to run at a speed of 400 MHz on this particular card. It features 16 SPUs along with 8 TAUs and 4 ROPs.

Compare those specs to the GeForce GTX 870M, which comes with a clock speed of 941 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It features 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 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 better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 maximum fill rate.
