GeForce GTX 965M vs Radeon HD 6670 (OEM) 1GB

Intro

The GeForce GTX 965M has a core clock frequency of 944 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 1024 SPUs, 64 TAUs, and 32 ROPs.

Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which features a core clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

The GeForce GTX 965M is much (more or less 215%) faster with regards to AF than the Radeon HD 6670 (OEM) 1GB. (explain)

GeForce GTX 965M 60416 Mtexels/sec
Radeon HD 6670 (OEM) 1GB 19200 Mtexels/sec
Difference: 41216 (215%)

Pixel Rate

The GeForce GTX 965M is a lot (approximately 372%) more effective at FSAA than the Radeon HD 6670 (OEM) 1GB, and also will be able to handle higher resolutions more effectively. (explain)

GeForce GTX 965M 30208 Mpixels/sec
Radeon HD 6670 (OEM) 1GB 6400 Mpixels/sec
Difference: 23808 (372%)

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 max amount of data (counted in megabytes 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 its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
