GeForce GT 1030 vs GeForce GTX 295

Intro

Compare those specifications to the GeForce GTX 295, which uses a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this model. It features 240 SPUs along with 80 Texture Address Units and 28 ROPs.

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

Memory Bandwidth

Theoretically speaking, the GeForce GTX 295 should be 355% quicker than the GeForce GT 1030 overall, due to its greater bandwidth. (explain)

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

Texel Rate

The GeForce GTX 295 should be quite a bit (approximately 128%) better at AF 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 a high screen resolution 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 (measured in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
