GeForce 9800 GT 1GB vs GeForce GTX 650 Ti

Intro

Compare all that to the GeForce GTX 650 Ti, which has GPU clock speed of 928 MHz, and 1024 MB of GDDR5 RAM running at 1350 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 9800 GT 1GB		105 Watts
GeForce GTX 650 Ti		110 Watts
	Difference: 5 Watts (5%)

Memory Bandwidth

Theoretically, the GeForce GTX 650 Ti should perform quite a bit faster than the GeForce 9800 GT 1GB overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
GeForce 9800 GT 1GB		57600 MB/sec
	Difference: 28800 (50%)

Texel Rate

The GeForce GTX 650 Ti should be a lot (about 77%) better at anisotropic filtering than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 25792 (77%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 650 Ti is superior to the GeForce 9800 GT 1GB, and very much so. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 5248 (55%)

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 moved past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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