GeForce GTX 295 vs Radeon RX 470

Intro

Compare all that to the Radeon RX 470, which features a clock frequency of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also features a 256-bit bus, and uses a 14 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Memory Bandwidth

Performance-wise, the GeForce GTX 295 should theoretically be a little bit superior to the Radeon RX 470 overall. (explain)

GeForce GTX 295		223776 MB/sec
Radeon RX 470		211200 MB/sec
	Difference: 12576 (6%)

Texel Rate

The Radeon RX 470 should be quite a bit (about 29%) faster with regards to texture filtering than the GeForce GTX 295. (explain)

Radeon RX 470		118528 Mtexels/sec
GeForce GTX 295		92160 Mtexels/sec
	Difference: 26368 (29%)

Pixel Rate

The GeForce GTX 295 should be a bit (more or less 9%) faster with regards to anti-aliasing than the Radeon RX 470, and will be capable of handling higher resolutions without losing too much performance. (explain)

GeForce GTX 295		32256 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 2624 (9%)

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 maximum amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video 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 most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
