GeForce 9800 GT 1GB vs GeForce GTX 950M

Intro

The GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM works at a speed of 900 MHz on this model. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has set the core frequency at 914 MHz. The DDR3 memory runs at a frequency of 1000 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

GeForce GTX 950M 32000 MB/sec
Difference: 25600 (80%)

Texel Rate

The GeForce GTX 950M is just a bit (about 9%) faster with regards to AF than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 950M 36560 Mtexels/sec
GeForce 9800 GT 1GB 33600 Mtexels/sec
Difference: 2960 (9%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950M is superior to the GeForce 9800 GT 1GB, and very much so. (explain)

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's 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 ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 can be applied per second. This is calculated by multiplying the total amount of texture units 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 in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
