GeForce GTS 450 vs GeForce GTX 860M

Intro

The GeForce GTS 450 uses a 40 nm design. nVidia has set the core frequency at 783 MHz. The GDDR5 RAM runs at a frequency of 902 MHz on this particular model. It features 192 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 860M, which has core clock speeds of 797 MHz on the GPU, and 1000 MHz on the 4096 MB of GDDR5 RAM. It features 1152 SPUs as well as 96 TAUs and 16 ROPs.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 860M is 11% quicker than the GeForce GTS 450 overall, because of its higher data rate. (explain)

GeForce GTX 860M 64000 MB/sec
GeForce GTS 450 57728 MB/sec
Difference: 6272 (11%)

Texel Rate

The GeForce GTX 860M should be quite a bit (about 205%) more effective at anisotropic filtering than the GeForce GTS 450. (explain)

GeForce GTX 860M 76512 Mtexels/sec
GeForce GTS 450 25056 Mtexels/sec
Difference: 51456 (205%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 860M is a better choice, though only just barely. (explain)

GeForce GTX 860M 12752 Mpixels/sec
GeForce GTS 450 12528 Mpixels/sec
Difference: 224 (2%)

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 max amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
