GeForce GTS 150 vs GeForce GTX 1630

Intro

Compare all that to the GeForce GTX 1630, which comes with GPU clock speed of 1740 MHz, and 4096 MB of GDDR6 RAM set to run at 1500 MHz through a 64-bit bus. It also is comprised of 512 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTS 150		141 Watts
	Difference: 66 Watts (88%)

Memory Bandwidth

In theory, the GeForce GTX 1630 will be 207% quicker than the GeForce GTS 150 in general, because of its higher data rate. (explain)

GeForce GTX 1630		98304 MB/sec
GeForce GTS 150		32000 MB/sec
	Difference: 66304 (207%)

Texel Rate

The GeForce GTX 1630 should be just a bit (more or less 18%) faster with regards to texture filtering than the GeForce GTS 150. (explain)

GeForce GTX 1630		55680 Mtexels/sec
GeForce GTS 150		47360 Mtexels/sec
	Difference: 8320 (18%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 1630 is the winner, by a large margin. (explain)

GeForce GTX 1630		27840 Mpixels/sec
GeForce GTS 150		11840 Mpixels/sec
	Difference: 16000 (135%)

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 moved past the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
