GeForce GT 230 vs GeForce GTX 960M

Intro

Compare those specs to the GeForce GTX 960M, which makes use of a 28 nm design. nVidia has clocked the core speed at 1096 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce GTX 960M should theoretically be much faster than the GeForce GT 230 in general. (explain)

GeForce GTX 960M		64000 MB/sec
GeForce GT 230		38400 MB/sec
	Difference: 25600 (67%)

Texel Rate

The GeForce GTX 960M is quite a bit (more or less 398%) faster with regards to AF than the GeForce GT 230. (explain)

GeForce GTX 960M		43840 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 35040 (398%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 960M is a better choice, by far. (explain)

GeForce GTX 960M		17536 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 13136 (299%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
