GeForce GTX 275 vs Radeon RX 460 2GB

Intro

Compare those specifications to the Radeon RX 460 2GB, which has GPU clock speed of 1090 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 460 2GB		75 Watts
GeForce GTX 275		219 Watts
	Difference: 144 Watts (192%)

Memory Bandwidth

The GeForce GTX 275, in theory, should perform a bit faster than the Radeon RX 460 2GB overall. (explain)

GeForce GTX 275		127008 MB/sec
Radeon RX 460 2GB		112000 MB/sec
	Difference: 15008 (13%)

Texel Rate

The Radeon RX 460 2GB should be quite a bit (about 21%) faster with regards to texture filtering than the GeForce GTX 275. (explain)

Radeon RX 460 2GB		61040 Mtexels/sec
GeForce GTX 275		50640 Mtexels/sec
	Difference: 10400 (21%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 275 is a better choice, but only just. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon RX 460 2GB		17440 Mpixels/sec
	Difference: 284 (2%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is worked out 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write 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 speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
