GeForce 920M vs GeForce GTX 465

Intro

Compare all of that to the GeForce GTX 465, which comes with core speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs as well as 44 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 465 will be 612% quicker than the GeForce 920M in general, due to its greater data rate. (explain)

GeForce GTX 465		102592 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 88192 (612%)

Texel Rate

The GeForce 920M should be just a bit (more or less 14%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce 920M		30528 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 3820 (14%)

Pixel Rate

The GeForce GTX 465 will be much (approximately 155%) faster with regards to full screen anti-aliasing than the GeForce 920M, and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 465		19424 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 11792 (155%)

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 (in units of MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
