GeForce GTX 260 Core 216 vs GeForce GTX 650 Ti 2GB

Intro

Compare all that to the GeForce GTX 650 Ti 2GB, which comes with GPU clock speed of 928 MHz, and 2048 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 Ti 2GB		110 Watts
GeForce GTX 260 Core 216		202 Watts
	Difference: 92 Watts (84%)

Memory Bandwidth

The GeForce GTX 260 Core 216 should in theory perform quite a bit faster than the GeForce GTX 650 Ti 2GB in general. (explain)

GeForce GTX 260 Core 216		111888 MB/sec
GeForce GTX 650 Ti 2GB		86400 MB/sec
	Difference: 25488 (30%)

Texel Rate

The GeForce GTX 650 Ti 2GB should be much (approximately 43%) more effective at AF than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 650 Ti 2GB		59392 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 17920 (43%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 260 Core 216 is superior to the GeForce GTX 650 Ti 2GB, not by a very large margin though. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce GTX 650 Ti 2GB		14848 Mpixels/sec
	Difference: 1280 (9%)

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 (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be applied per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
