GeForce GTX 1650 vs GeForce GTX 280

Intro

Compare all that to the GeForce GTX 280, which makes use of a 65 nm design. nVidia has clocked the core frequency at 602 MHz. The GDDR3 RAM is set to run at a frequency of 1107 MHz on this specific model. It features 240 SPUs along with 80 TAUs and 32 ROPs.

GeForce GTX 1650		131072 MB/sec
	Difference: 10624 (8%)

Texel Rate

The GeForce GTX 1650 is much (more or less 73%) faster with regards to AF than the GeForce GTX 280. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GTX 280		48160 Mtexels/sec
	Difference: 35000 (73%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 1650 is the winner, by a large margin. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 28256 (147%)

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: Bandwidth is the max amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
