Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
GeForce 9800 GX2		197 Watts
	Difference: 122 Watts (163%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1650 is 2% quicker than the GeForce 9800 GX2 overall, because of its higher bandwidth. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce 9800 GX2		128000 MB/sec
	Difference: 3072 (2%)

Texel Rate

The GeForce GTX 1650 is a little bit (more or less 8%) better at AF than the GeForce 9800 GX2. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce 9800 GX2		76800 Mtexels/sec
	Difference: 6360 (8%)

Pixel Rate

The GeForce GTX 1650 is much (more or less 148%) more effective at anti-aliasing than the GeForce 9800 GX2, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce 9800 GX2		19200 Mpixels/sec
	Difference: 28320 (148%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units by the core 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 processed in one second.

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