GeForce GTX 960M vs Radeon HD 6670 (OEM) 1GB

Intro

The GeForce GTX 960M features a GPU clock speed of 1096 MHz, and the 2048 MB of GDDR5 memory runs at 1000 MHz through a 128-bit bus. It also is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Compare all of that to the Radeon HD 6670 (OEM) 1GB, which has core speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6670 (OEM) 1GB 63 Watts
GeForce GTX 960M 65 Watts
Difference: 2 Watts (3%)

Memory Bandwidth

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

Texel Rate

The GeForce GTX 960M will be much (approximately 128%) more effective at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)

GeForce GTX 960M 43840 Mtexels/sec
Radeon HD 6670 (OEM) 1GB 19200 Mtexels/sec
Difference: 24640 (128%)

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 6670 (OEM) 1GB 6400 Mpixels/sec
Difference: 11136 (174%)

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 (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units of the card by the core 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 the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
