GeForce GTX 1650 vs Radeon HD 5770

Intro

Compare those specs to the Radeon HD 5770, which uses a 40 nm design. AMD has set the core speed at 850 MHz. The GDDR5 RAM runs at a frequency of 1200 MHz on this specific card. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon HD 5770		108 Watts
	Difference: 33 Watts (44%)

Memory Bandwidth

In theory, the GeForce GTX 1650 should be 71% quicker than the Radeon HD 5770 in general, because of its greater data rate. (explain)

GeForce GTX 1650		131072 MB/sec
Radeon HD 5770		76800 MB/sec
	Difference: 54272 (71%)

Texel Rate

The GeForce GTX 1650 should be a lot (about 145%) better at texture filtering than the Radeon HD 5770. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 5770		34000 Mtexels/sec
	Difference: 49160 (145%)

Pixel Rate

The GeForce GTX 1650 should be quite a bit (about 249%) more effective at FSAA than the Radeon HD 5770, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 5770		13600 Mpixels/sec
	Difference: 33920 (249%)

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 data (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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 ability to reach the maximum fill rate.
