GeForce GTX 285 1GB vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which makes use of a 28 nm design. nVidia has clocked the core speed at 1024 MHz. The GDDR5 memory is set to run at a frequency of 1652 MHz on this model. It features 768 SPUs as well as 48 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 950		90 Watts
GeForce GTX 285 1GB		204 Watts
	Difference: 114 Watts (127%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 285 1GB will be 50% quicker than the GeForce GTX 950 in general, because of its higher bandwidth. (explain)

GeForce GTX 285 1GB		158976 MB/sec
GeForce GTX 950		105728 MB/sec
	Difference: 53248 (50%)

Texel Rate

The GeForce GTX 285 1GB should be just a bit (about 5%) more effective at texture filtering than the GeForce GTX 950. (explain)

GeForce GTX 285 1GB		51840 Mtexels/sec
GeForce GTX 950		49152 Mtexels/sec
	Difference: 2688 (5%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 950 is superior to the GeForce GTX 285 1GB, and very much so. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce GTX 285 1GB		20736 Mpixels/sec
	Difference: 12032 (58%)

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 transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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