Radeon R9 270 vs Radeon R9 270X

Intro

The Radeon R9 270 features core speeds of 900 MHz on the GPU, and 1400 MHz on the 2048 MB of GDDR5 memory. It features 1280 SPUs along with 80 TAUs and 32 ROPs.

Compare all of that to the Radeon R9 270X, which uses a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1400 MHz on this specific card. It features 1280 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.

Radeon R9 270 150 Watts
Radeon R9 270X 180 Watts
Difference: 30 Watts (20%)

Memory Bandwidth

Both cards have the exact same bandwidth, so theoretically they should have the same performance. (explain)

Texel Rate

The Radeon R9 270X should be a little bit (more or less 11%) more effective at anisotropic filtering than the Radeon R9 270. (explain)

Radeon R9 270X 80000 Mtexels/sec
Radeon R9 270 72000 Mtexels/sec
Difference: 8000 (11%)

Pixel Rate

The Radeon R9 270X will be a small bit (about 11%) better at FSAA than the Radeon R9 270, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 270X 32000 Mpixels/sec
Radeon R9 270 28800 Mpixels/sec
Difference: 3200 (11%)

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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.

Asus R9270X-DC2T-2GD5 is the best graphic card f the year.i love it.it works very smooth with no noise.i had played battlefield 4 in ultra graphics.

MG says:

Now looking back several months later, it seems like the R9270 can be clocked to run just as well as the 270X. This makes the 270 the better deal, even more than the NVidia equivalent. If you have the choice, get the 270 instead of the 270X, unless you find that they're only a few bucks apart.

Josh says:

I've ran the 270 vs my friends comp which is running the 270x and in every benchmark I've blown his card away,

lolno says:

Josh u have not blown a 270X away with ur 270 even not if u have overclocked ur 270.

ROFLHELLNO says:

The 270x can be overclocked as well. And Josh if you are "blowing away" your friends 270x with your 270, something is bad wrong with his system.

Blair says:

Actually the 270 can match the 270X clock for clock. They are both the exact same chip, All they did was clock one higher and slap a X on it. Now some R9 270 models can't overclock as much as the 270X but most can. This is why they are not priced very far apart either. I got the 270 because I am cheap but I wanted a High End GPU, Some may claim it is only High mid or whatever, But this card is a high end model. All R9's are high end. Just like Nvidia Starting with the 760 they are all high end.

Tom says:

I run a 270 non X also. I keep mine set at 1050mhz all the time. I have tried 1100mhz and was very impressed with how it performed. I was beating most GTX 760 Benchmarks with it at 1100mhz, But I keep it 1050mhz because I want to keep it awhile, And it performs outstandingly enough at stock 925mhz. At 1050mhz All my games can be cranked way up with FPS that everyone hopes for.

Morten says:

I actually got a 270 + 270x setup atm, running crossfire, overclocked both mems to 1450 and the 270 up to 1050 and the 270x up to 1120. got an awesome boost 🙂 tomorrow gonna try and extra pci cooler blowing air directly at the 270 mounted on the bottom, hope it will be slightly cooler so i can clock it to 1100 🙂 the clocking i did today brought me up to 17k graphic points in 3d mark basic 🙂 great cards both of them 🙂

Morten says:

got the 270x used btw in norway at around 120 buckaroons 🙂 4gb version 😀

Anders says:

I picked up the Asus r9 270, it runs at a stock 975mhz and can easily run 1Gz just like the 270x. Its a bargain at its price level right now.

nelly says:

30 extra watts for a couple of FPS is pretty lame for the same price of a 270X i can get the more powerful 760 but i don't really need all that juice and i hate hot cards anything above 150 watts is a no no i don't give a fuck about how efficient the cooler is
