GeForce GT 210 vs GeForce GTX 465

Intro

Compare all that to the GeForce GTX 465, which features a GPU core clock speed of 607 MHz, and 1024 MB of GDDR5 memory running at 802 MHz through a 256-bit bus. It also is made up of 352 SPUs, 44 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GTX 465		200 Watts
	Difference: 169 Watts (545%)

Memory Bandwidth

In theory, the GeForce GTX 465 will be 702% quicker than the GeForce GT 210 in general, due to its higher bandwidth. (explain)

GeForce GTX 465		102592 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 89792 (702%)

Texel Rate

The GeForce GTX 465 should be a lot (about 467%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)

GeForce GTX 465		26708 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 21996 (467%)

Pixel Rate

The GeForce GTX 465 is quite a bit (approximately 724%) better at full screen anti-aliasing than the GeForce GT 210, and should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 17068 (724%)

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: Memory bandwidth is the largest amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. 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 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 maximum fill rate.
