GeForce 9800 GT 1GB vs GeForce GTX 965M

Intro

The GeForce 9800 GT 1GB makes use of 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 along with 56 TAUs and 16 ROPs.

Compare those specifications to the GeForce GTX 965M, which has core clock speeds of 944 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 1024 SPUs along with 64 TAUs and 32 ROPs.

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

Theoretically speaking, the GeForce GTX 965M should be 11% quicker than the GeForce 9800 GT 1GB overall, because of its greater bandwidth. (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 a lot (about 80%) more effective at texture filtering 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 965M is superior to the GeForce 9800 GT 1GB, 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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
