GeForce GTX 295 vs Radeon RX 570

Intro

Compare those specifications to the Radeon RX 570, which makes use of a 14 nm design. AMD has clocked the core frequency at 1168 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

GeForce GTX 295		92160 Mtexels/sec
	Difference: 57344 (62%)

Pixel Rate

The Radeon RX 570 will be a small bit (about 16%) faster with regards to anti-aliasing than the GeForce GTX 295, and capable of handling higher resolutions better. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 295		32256 Mpixels/sec
	Difference: 5120 (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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 are processed per second. This number is calculated by multiplying the total texture units 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 most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs 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 is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
