Compare any two graphics cards:
Radeon R9 270X vs Radeon R9 280X
IntroThe Radeon R9 270X features a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1400 MHz. It also makes use of a 256-bit memory bus, and makes use of a 28 nm design. It is made up of 1280 SPUs, 80 TAUs, and 32 ROPs.Compare those specifications to the Radeon R9 280X, which has a core clock speed of 850 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 280X should be quite a bit faster than the Radeon R9 270X in general. (explain)
Texel RateThe Radeon R9 280X should be a lot (approximately 36%) more effective at anisotropic filtering than the Radeon R9 270X. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon R9 270X is superior to the Radeon R9 280X, but not by far. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount 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 rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.

7 Responses to “Radeon R9 270X vs Radeon R9 280X”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 😛
mb/s should be more accurate
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
hi i have 530 watt power suply.
it's enoght for r9 280x ???
@vahid_dez. yes it will.
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
