VS

GeForce GTX 260 Core 216 vs GeForce GTX 470

Intro

The GeForce GTX 260 Core 216 uses a 65 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory works at a frequency of 999 MHz on this specific card. It features 216 SPUs as well as 72 TAUs and 28 ROPs.

Compare those specifications to the GeForce GTX 470, which features GPU core speed of 607 MHz, and 1280 MB of GDDR5 RAM running at 837 MHz through a 320-bit bus. It also is comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 260 Core 216 202 Watts
GeForce GTX 470 215 Watts
Difference: 13 Watts (6%)

Memory Bandwidth

In theory, the GeForce GTX 470 should be a small bit faster than the GeForce GTX 260 Core 216 overall. (explain)

GeForce GTX 470 133920 MB/sec
GeForce GTX 260 Core 216 111888 MB/sec
Difference: 22032 (20%)

Texel Rate

The GeForce GTX 260 Core 216 should be much (more or less 22%) faster with regards to texture filtering than the GeForce GTX 470. (explain)

GeForce GTX 260 Core 216 41472 Mtexels/sec
GeForce GTX 470 33992 Mtexels/sec
Difference: 7480 (22%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 470 is the winner, and very much so. (explain)

GeForce GTX 470 24280 Mpixels/sec
GeForce GTX 260 Core 216 16128 Mpixels/sec
Difference: 8152 (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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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