GeForce GT 1030 vs GeForce GTX 295

Intro

Compare those specs to the GeForce GTX 295, which features core speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 28 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 1030		30 Watts
GeForce GTX 295		289 Watts
	Difference: 259 Watts (863%)

Memory Bandwidth

In theory, the GeForce GTX 295 should be 355% faster than the GeForce GT 1030 in general, because of its higher data rate. (explain)

GeForce GTX 295		223776 MB/sec
GeForce GT 1030		49152 MB/sec
	Difference: 174624 (355%)

Texel Rate

The GeForce GTX 295 will be quite a bit (about 128%) faster with regards to texture filtering than the GeForce GT 1030. (explain)

GeForce GTX 295		92160 Mtexels/sec
GeForce GT 1030		40480 Mtexels/sec
	Difference: 51680 (128%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 295 is superior to the GeForce GT 1030, by a large margin. (explain)

GeForce GTX 295		32256 Mpixels/sec
GeForce GT 1030		20240 Mpixels/sec
	Difference: 12016 (59%)

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: Bandwidth is the max amount of information (in units of MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the 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 - 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
