GeForce GTX 960M vs Radeon HD 5670

Intro

The GeForce GTX 960M uses a 28 nm design. nVidia has clocked the core frequency at 1096 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this specific card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Compare those specifications to the Radeon HD 5670, which features core clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs along with 20 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 5670 61 Watts
GeForce GTX 960M 65 Watts
Difference: 4 Watts (7%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The GeForce GTX 960M is quite a bit (more or less 183%) more effective at texture filtering than the Radeon HD 5670. (explain)

GeForce GTX 960M 43840 Mtexels/sec
Radeon HD 5670 15500 Mtexels/sec
Difference: 28340 (183%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 960M is a better choice, and very much so. (explain)

GeForce GTX 960M 17536 Mpixels/sec
Radeon HD 5670 6200 Mpixels/sec
Difference: 11336 (183%)

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 megabytes per second) that can be moved over the external memory interface in a second. It 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 DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
