GeForce GTX 1630 vs GeForce GTX 295

Intro

Compare those specifications to the GeForce GTX 295, which comes with core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs along with 80 TAUs and 28 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1630		75 Watts
GeForce GTX 295		289 Watts
	Difference: 214 Watts (285%)

Memory Bandwidth

In theory, the GeForce GTX 295 should perform quite a bit faster than the GeForce GTX 1630 overall. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GTX 1630		98304 MB/sec
	Difference: 125472 (128%)

Texel Rate

The GeForce GTX 295 is quite a bit (more or less 66%) faster with regards to anisotropic filtering than the GeForce GTX 1630. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GTX 1630		55680 Mtexels/sec
	Difference: 36480 (66%)

Pixel Rate

The GeForce GTX 295 will be a little bit (approximately 16%) better at anti-aliasing than the GeForce GTX 1630, and also should be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GTX 1630		27840 Mpixels/sec
	Difference: 4416 (16%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. 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 many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
