GeForce 9800 GT 1GB vs GeForce GTX 860M

Intro

The GeForce 9800 GT 1GB comes with a GPU core speed of 600 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also features 112 Stream Processors, 56 TAUs, and 16 ROPs.

Compare all that to the GeForce GTX 860M, which comes with clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 memory. It features 1152 SPUs along with 96 TAUs and 16 Rasterization Operator Units.

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

Texel Rate

The GeForce GTX 860M is a lot (approximately 128%) more effective at texture filtering than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 860M 76512 Mtexels/sec
GeForce 9800 GT 1GB 33600 Mtexels/sec
Difference: 42912 (128%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 860M is the winner, by a large margin. (explain)

GeForce GTX 860M 12752 Mpixels/sec
GeForce 9800 GT 1GB 9600 Mpixels/sec
Difference: 3152 (33%)

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 max amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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