GeForce GTX 460 vs Radeon R9 M265X

Intro

Compare all of that to the Radeon R9 M265X, which makes use of a 28 nm design. AMD has clocked the core speed at 575 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this model. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 460 should in theory perform a little bit faster than the Radeon R9 M265X overall. (explain)

GeForce GTX 460		86400 MB/sec
Radeon R9 M265X		72000 MB/sec
	Difference: 14400 (20%)

Texel Rate

The GeForce GTX 460 is quite a bit (about 64%) more effective at anisotropic filtering than the Radeon R9 M265X. (explain)

GeForce GTX 460		37800 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 14800 (64%)

Pixel Rate

The GeForce GTX 460 will be much (approximately 76%) faster with regards to AA than the Radeon R9 M265X, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce GTX 460		16200 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 7000 (76%)

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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the clock 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 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 reach the max fill rate.
