GeForce GTX 960 vs Radeon HD 4850 X2 512MB

Intro

The GeForce GTX 960 features a GPU core speed of 1127 MHz, and the 2048 MB of GDDR5 memory is set to run at 1750 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 32 Raster Operation Units.

Compare those specifications to the Radeon HD 4850 X2 512MB, which features core clock speeds of 625 MHz on the GPU, and 993 MHz on the 512 MB of GDDR3 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Theoretically speaking, the Radeon HD 4850 X2 512MB should be 13% faster than the GeForce GTX 960 overall, because of its greater data rate. (explain)

Radeon HD 4850 X2 512MB 127104 MB/sec
GeForce GTX 960 112000 MB/sec
Difference: 15104 (13%)

Texel Rate

The GeForce GTX 960 is quite a bit (approximately 44%) faster with regards to anisotropic filtering than the Radeon HD 4850 X2 512MB. (explain)

GeForce GTX 960 72128 Mtexels/sec
Radeon HD 4850 X2 512MB 50000 Mtexels/sec
Difference: 22128 (44%)

Pixel Rate

The GeForce GTX 960 should be much (approximately 80%) more effective at full screen anti-aliasing than the Radeon HD 4850 X2 512MB, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 960 36064 Mpixels/sec
Radeon HD 4850 X2 512MB 20000 Mpixels/sec
Difference: 16064 (80%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Memory Bandwidth: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
