GeForce GT 340 vs GeForce GTX 1650

Intro

Compare all that to the GeForce GTX 1650, which comes with GPU core speed of 1485 MHz, and 4096 MB of GDDR5 RAM running at 2001 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 340		69 Watts
GeForce GTX 1650		75 Watts
	Difference: 6 Watts (9%)

Memory Bandwidth

In theory, the GeForce GTX 1650 should be 141% quicker than the GeForce GT 340 overall, due to its greater bandwidth. (explain)

GeForce GTX 1650		131072 MB/sec
GeForce GT 340		54400 MB/sec
	Difference: 76672 (141%)

Texel Rate

The GeForce GTX 1650 is a lot (more or less 373%) faster with regards to texture filtering than the GeForce GT 340. (explain)

GeForce GTX 1650		83160 Mtexels/sec
GeForce GT 340		17600 Mtexels/sec
	Difference: 65560 (373%)

Pixel Rate

The GeForce GTX 1650 will be quite a bit (more or less 980%) faster with regards to full screen anti-aliasing than the GeForce GT 340, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 1650		47520 Mpixels/sec
GeForce GT 340		4400 Mpixels/sec
	Difference: 43120 (980%)

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 maximum amount of information (measured in megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface 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 better 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, 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 amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
