GeForce GT 430 vs GeForce GTX 1050

Intro

Compare those specs to the GeForce GTX 1050, which comes with a clock frequency of 1354 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 32 ROPs.

GeForce GT 430		28800 MB/sec
	Difference: 85888 (298%)

Texel Rate

The GeForce GTX 1050 is quite a bit (about 384%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 1050		54160 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 42960 (384%)

Pixel Rate

The GeForce GTX 1050 should be a lot (approximately 1447%) better at AA than the GeForce GT 430, and also should be able to handle higher resolutions more effectively. (explain)

GeForce GTX 1050		43328 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 40528 (1447%)

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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
