GeForce 9800 GX2 vs Geforce GTX 760

Intro

Compare all that to the Geforce GTX 760, which has GPU clock speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also is made up of 1152 SPUs, 96 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 760		170 Watts
GeForce 9800 GX2		197 Watts
	Difference: 27 Watts (16%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 will be 50% faster than the GeForce 9800 GX2 overall, due to its higher data rate. (explain)

Geforce GTX 760		192256 MB/sec
GeForce 9800 GX2		128000 MB/sec
	Difference: 64256 (50%)

Texel Rate

The Geforce GTX 760 should be a lot (approximately 23%) better at texture filtering than the GeForce 9800 GX2. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 9800 GX2		76800 Mtexels/sec
	Difference: 17280 (23%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 760 is a better choice, by far. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 9800 GX2		19200 Mpixels/sec
	Difference: 12160 (63%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock speed of the card. 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 also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
