GeForce GTX 1650 vs Radeon HD 6950

Intro

Compare all of that to the Radeon HD 6950, which comes with core speeds of 800 MHz on the GPU, and 1250 MHz on the 1024 MB of GDDR5 memory. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1650		75 Watts
Radeon HD 6950		200 Watts
	Difference: 125 Watts (167%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6950 should be 22% quicker than the GeForce GTX 1650 in general, due to its higher data rate. (explain)

Radeon HD 6950		160000 MB/sec
GeForce GTX 1650		131072 MB/sec
	Difference: 28928 (22%)

Texel Rate

The GeForce GTX 1650 is a little bit (more or less 18%) faster with regards to texture filtering than the Radeon HD 6950. (explain)

GeForce GTX 1650		83160 Mtexels/sec
Radeon HD 6950		70400 Mtexels/sec
	Difference: 12760 (18%)

Pixel Rate

The GeForce GTX 1650 should be much (approximately 86%) better at AA than the Radeon HD 6950, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 1650		47520 Mpixels/sec
Radeon HD 6950		25600 Mpixels/sec
	Difference: 21920 (86%)

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 largest amount of information (in units of MB per second) that can be transported across the external memory interface in 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 must 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 anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
