Radeon R9 270X vs Radeon R9 280X

Intro

The Radeon R9 270X comes with a GPU core speed of 1000 MHz, and the 2048 MB of GDDR5 memory is set to run at 1400 MHz through a 256-bit bus. It also is made up of 1280 SPUs, 80 Texture Address Units, and 32 Raster Operation Units.

Compare that to the Radeon R9 280X, which uses a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 are applied in one second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better 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 most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.

Hello, i have a question.
appears in yours table that the memory bandwidth is measured by MB/s, however I see in another website that measured memory bandwidth as GB/s , wich one is correct ?
Thanks, and sorry for my bad english 😛

nima says:

mb/s should be more accurate

SAM says:

their both correct 1 gb equals 1024 mb, so the Memory Bandwidth of amd r9 280x which is 179200 mb would be around 175gb/sec

vahid_dez says:

hi i have 530 watt power suply.
it's enoght for r9 280x ???

Robin says:

@vahid_dez. yes it will.

rob says:

i am just wondering if upgrading from the R9270 2 gb to the R280X 3g will help me with locked $g video i experience from time to time it will be 100.00 differece in price thx rob
