GeForce GTX 1050 3GB vs GeForce GTX 650

Intro

The GeForce GTX 1050 3GB has a GPU core clock speed of 1392 MHz, and the 3072 MB of GDDR5 RAM is set to run at 1750 MHz through a 96-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 24 Raster Operation Units.

Compare all of that to the GeForce GTX 650, which comes with a core clock frequency of 1058 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 650 64 Watts
GeForce GTX 1050 3GB 75 Watts
Difference: 11 Watts (17%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 1050 3GB is 8% quicker than the GeForce GTX 650 overall, due to its higher data rate. (explain)

GeForce GTX 1050 3GB 86016 MB/sec
GeForce GTX 650 80000 MB/sec
Difference: 6016 (8%)

Texel Rate

The GeForce GTX 1050 3GB should be a lot (more or less 97%) more effective at texture filtering than the GeForce GTX 650. (explain)

GeForce GTX 1050 3GB 66816 Mtexels/sec
GeForce GTX 650 33856 Mtexels/sec
Difference: 32960 (97%)

Pixel Rate

The GeForce GTX 1050 3GB should be quite a bit (about 97%) faster with regards to AA than the GeForce GTX 650, and also should be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 1050 3GB 33408 Mpixels/sec
GeForce GTX 650 16928 Mpixels/sec
Difference: 16480 (97%)

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 maximum amount of data (in units of megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better 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 texture map elements (texels) that are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
