GeForce GTX 960M vs Radeon HD 3850 X2

Intro

The GeForce GTX 960M uses a 28 nm design. nVidia has set the core frequency at 1096 MHz. The GDDR5 memory works at a frequency of 1000 MHz on this specific card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Compare all of that to the Radeon HD 3850 X2, which has a GPU core clock speed of 668 MHz, and 512 MB of GDDR3 memory running at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 3850 X2 should theoretically be much superior to the GeForce GTX 960M in general. (explain)

Radeon HD 3850 X2 105984 MB/sec
GeForce GTX 960M 64000 MB/sec
Difference: 41984 (66%)

Texel Rate

The GeForce GTX 960M will be much (approximately 105%) faster with regards to texture filtering than the Radeon HD 3850 X2. (explain)

GeForce GTX 960M 43840 Mtexels/sec
Radeon HD 3850 X2 21376 Mtexels/sec
Difference: 22464 (105%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 3850 X2 is superior to the GeForce GTX 960M, by far. (explain)

Radeon HD 3850 X2 21376 Mpixels/sec
GeForce GTX 960M 17536 Mpixels/sec
Difference: 3840 (22%)

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 maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are applied per second. This figure is worked out 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 graphics 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 amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
