GeForce GTX 465 vs Radeon R9 M365X

Intro

Compare those specifications to the Radeon R9 M365X, which makes use of a 28 nm design. AMD has clocked the core frequency at 925 MHz. The GDDR5 RAM works at a frequency of 1125 MHz on this card. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the GeForce GTX 465 should in theory be a lot superior to the Radeon R9 M365X in general. (explain)

GeForce GTX 465		102592 MB/sec
Radeon R9 M365X		72000 MB/sec
	Difference: 30592 (42%)

Texel Rate

The Radeon R9 M365X should be quite a bit (more or less 39%) faster with regards to texture filtering than the GeForce GTX 465. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 10292 (39%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 465 is superior to the Radeon R9 M365X, and very much so. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon R9 M365X		14800 Mpixels/sec
	Difference: 4624 (31%)

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 information (in units of megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 can be processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
