GeForce 9800 GT 1GB vs GeForce GTX 965M

Intro

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

Compare those specs to the GeForce GTX 965M, which comes with GPU clock speed of 944 MHz, and 2048 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also is made up of 1024 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 965M 60 Watts
GeForce 9800 GT 1GB 105 Watts
Difference: 45 Watts (75%)

Memory Bandwidth

In theory, the GeForce GTX 965M will be 11% quicker than the GeForce 9800 GT 1GB overall, because of its greater data rate. (explain)

GeForce GTX 965M 64000 MB/sec
GeForce 9800 GT 1GB 57600 MB/sec
Difference: 6400 (11%)

Texel Rate

The GeForce GTX 965M will be much (approximately 80%) better at AF than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce 9800 GT 1GB 33600 Mtexels/sec
Difference: 26816 (80%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 965M is the winner, by a large margin. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 20608 (215%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a 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 amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 - the lower the bandwidth is, the lower the potential to reach the max fill rate.
