GeForce GT 230 vs GeForce GTX 650 Ti

Intro

Compare those specs to the GeForce GTX 650 Ti, which has a core clock frequency of 928 MHz and a GDDR5 memory speed of 1350 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 768 SPUs, 64 TAUs, and 16 ROPs.

GeForce GT 230		38400 MB/sec
	Difference: 48000 (125%)

Texel Rate

The GeForce GTX 650 Ti is a lot (about 575%) better at texture filtering than the GeForce GT 230. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 50592 (575%)

Pixel Rate

The GeForce GTX 650 Ti should be quite a bit (about 237%) faster with regards to anti-aliasing than the GeForce GT 230, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 10448 (237%)

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 data (measured in MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
