GeForce GTX 285 2GB vs Radeon R9 M365X

Intro

The GeForce GTX 285 2GB makes use of a 55 nm design. nVidia has set the core speed at 648 MHz. The GDDR3 RAM is set to run at a frequency of 1242 MHz on this specific card. It features 240 SPUs as well as 80 Texture Address Units and 32 ROPs.

Compare all of that to the Radeon R9 M365X, which has GPU clock speed of 925 MHz, and 4096 MB of GDDR5 RAM running at 1125 MHz through a 128-bit bus. It also is made up of 640 Stream Processors, 40 TAUs, and 16 ROPs.

Radeon R9 M365X 72000 MB/sec
Difference: 86976 (121%)

Texel Rate

The GeForce GTX 285 2GB should be a lot (approximately 40%) more effective at AF than the Radeon R9 M365X. (explain)

GeForce GTX 285 2GB 51840 Mtexels/sec
Radeon R9 M365X 37000 Mtexels/sec
Difference: 14840 (40%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 285 2GB is the winner, and very much so. (explain)

GeForce GTX 285 2GB 20736 Mpixels/sec
Radeon R9 M365X 14800 Mpixels/sec
Difference: 5936 (40%)

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.

Memory Bandwidth: Bandwidth is the max amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total number of texture units of the card 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel 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 get to the maximum fill rate.
