GeForce GTX 280 vs GeForce GTX 650 Ti 2GB

Intro

Compare all that to the GeForce GTX 650 Ti 2GB, which uses a 28 nm design. nVidia has clocked the core speed at 928 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this card. It features 768 SPUs along with 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
GeForce GTX 280		236 Watts
	Difference: 126 Watts (115%)

Memory Bandwidth

The GeForce GTX 280 should in theory perform a lot faster than the GeForce GTX 650 Ti 2GB in general. (explain)

GeForce GTX 280		141696 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 55296 (64%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be quite a bit (more or less 23%) faster with regards to AF than the GeForce GTX 280. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GTX 280		48160 Mtexels/sec
	Difference: 11232 (23%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 280 is the winner, and very much so. (explain)

GeForce GTX 280		19264 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 4416 (30%)

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 (in units of MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 are applied per second. This number is worked out by multiplying the total amount 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
