GeForce GTX 465 vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which makes use of a 28 nm design. nVidia has set the core speed at 915 MHz. The GDDR5 RAM is set to run at a frequency of 1500 MHz on this particular model. It features 1344 SPUs along with 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Geforce GTX 670		170 Watts
GeForce GTX 465		200 Watts
	Difference: 30 Watts (18%)

Memory Bandwidth

The Geforce GTX 670 should in theory be quite a bit faster than the GeForce GTX 465 overall. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 89408 (87%)

Texel Rate

The Geforce GTX 670 is a lot (more or less 284%) faster with regards to AF than the GeForce GTX 465. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 75772 (284%)

Pixel Rate

The Geforce GTX 670 is quite a bit (approximately 51%) more effective at FSAA than the GeForce GTX 465, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Geforce GTX 670		29280 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 9856 (51%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
