GeForce GTX 285 1GB vs Radeon R9 280X
Intro
The GeForce GTX 285 1GB comes with core clock speeds of 648 MHz on the GPU, and 1242 MHz on the 1024 MB of GDDR3 memory. It features 240 SPUs along with 80 Texture Address Units and 32 ROPs.Compare all that to the Radeon R9 280X, which comes with core speeds of 850 MHz on the GPU, and 1500 MHz on the 3072 MB of GDDR5 RAM. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 can be processed in one second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.

Comments
One Response to “GeForce GTX 285 1GB vs Radeon R9 280X”I can't believe the 285GTX costs more than the R280X yet it's apparently a lot worse and it even uses outdated API versions.
But oh well, I guess it's normal because the 285GTX was released in 2009, while the R280X was released in 2013.
Still, pricing bullshit...And it still costs a lot more today!
