GeForce GTX 280 vs GeForce GTX 965M

Intro

The GeForce GTX 280 has clock speeds of 602 MHz on the GPU, and 1107 MHz on the 1024 MB of GDDR3 RAM. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Compare all that to the GeForce GTX 965M, which uses a 28 nm design. nVidia has set the core frequency at 944 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GTX 280 141696 MB/sec
GeForce GTX 965M 64000 MB/sec
Difference: 77696 (121%)

Texel Rate

The GeForce GTX 965M should be a lot (approximately 25%) more effective at texture filtering than the GeForce GTX 280. (explain)

GeForce GTX 965M 60416 Mtexels/sec
GeForce GTX 280 48160 Mtexels/sec
Difference: 12256 (25%)

Pixel Rate

The GeForce GTX 965M is a lot (approximately 57%) more effective at AA than the GeForce GTX 280, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 965M 30208 Mpixels/sec
GeForce GTX 280 19264 Mpixels/sec
Difference: 10944 (57%)

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 largest amount of information (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses 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 higher screen resolutions.

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

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