GeForce GTX 460 (OEM) vs GeForce GTX 460 1GB

Intro

The GeForce GTX 460 (OEM) uses a 40 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR5 RAM runs at a frequency of 850 MHz on this specific model. It features 336 SPUs along with 56 TAUs and 32 ROPs.

Compare those specifications to the GeForce GTX 460 1GB, which comes with core speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 460 (OEM) 150 Watts
GeForce GTX 460 1GB 160 Watts
Difference: 10 Watts (7%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 1GB will be 6% faster than the GeForce GTX 460 (OEM) in general, due to its greater bandwidth. (explain)

GeForce GTX 460 1GB 115200 MB/sec
GeForce GTX 460 (OEM) 108800 MB/sec
Difference: 6400 (6%)

Texel Rate

The GeForce GTX 460 1GB should be a small bit (more or less 4%) more effective at texture filtering than the GeForce GTX 460 (OEM). (explain)

GeForce GTX 460 1GB 37800 Mtexels/sec
GeForce GTX 460 (OEM) 36400 Mtexels/sec
Difference: 1400 (4%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 460 1GB is a better choice, but only just. (explain)

GeForce GTX 460 1GB 21600 Mpixels/sec
GeForce GTX 460 (OEM) 20800 Mpixels/sec
Difference: 800 (4%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
