GeForce 9500 GT DDR2 vs GeForce GTX 460 (OEM)

Intro

Compare all of that to the GeForce GTX 460 (OEM), which makes use of a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 memory runs at a speed of 850 MHz on this particular model. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Pixel Rate

The GeForce GTX 460 (OEM) will be much (more or less 373%) more effective at full screen anti-aliasing than the GeForce 9500 GT DDR2, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 460 (OEM)		20800 Mpixels/sec
GeForce 9500 GT DDR2		4400 Mpixels/sec
	Difference: 16400 (373%)

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 max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
