GeForce GTX 285 1GB vs Radeon R9 280X
Intro
The GeForce GTX 285 1GB comes with a clock frequency of 648 MHz and a GDDR3 memory speed of 1242 MHz. It also makes use of a 512-bit bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 32 Raster Operation Units.Compare all of that to the Radeon R9 280X, which has a clock speed of 850 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred across the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach 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vs Radeon R9 280X”I can't believe the 285GTX costs more than the R280X yet it's apparently a lot worse and it even uses outdated API versions.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!
