ASUS AMD Radeon R9 270 Direct CU II OC 2GB Graphics Card Review

ASUS Radeon R9 270 DC2 OC (12)

Another day, another graphics card release. It feels like I’ve been saying that a lot recently as AMD have gone a bit GPU-crazy with all their new RX 2XX products. Today we have another one of those releases from AMD and it is the R9 270. The R9 270 is the non-x variant of the R9 270X which we reviewed not that long ago. This means it is the spiritual successor to AMD’s HD 7850 from the previous generation series. What’s nice is that the R9 270 isn’t going to be a straight up rebrand of the HD 7850, it is actually physically different but we will get onto that in a moment… first I want to draw attention to the particular R9 270 we’re reviewing today. Sadly AMD couldn’t provide us with a reference R9 270 graphics card (which is always ideal for far comparison purposes), but we’ve still got a pretty sweet looking ASUS Direct CU II OC variant of the R9 270 instead. ASUS have fitted the R9 270 with their renowned Direct CU II cooling solution and given it the OC treatment which means it comes with a high factory overclock – 50MHz more than the reference design, as shown below in the GPU-Z screen shot. The memory frequency is kept at the stock level of 1.4GHz/5.6GHz actual/effective.


As we’ve briefly mentioned the R9 270 replaces the HD 7850 but it isn’t an identical GPU. The R9 270 actually comes with 256 more GCN stream processors and 4 more compute units (CUs) while being within that same 150W TDP board power envelope.


In terms of the raw specifications the 1280 stream processors and 20 compute units make this unit virtually identical to the HD 7870. The only difference is a lower clock speed of 925MHz, compared to 1GHz on the HD 7870, which means the R9 270 is capable of 2.37 TFLOPS versus the 2.56 TFLOPS on the HD 7870. There’s also only a single 6 pin power connector on the R9 270 compared to dual 6 pin connectors on the HD 7870. Despite a lower core engine clock there is a much higher effective memory speed of 5600MHz compared to 4800MHz on the HD 7870 which should balance out some of that lost performance due to the lower core clock. The R9 270 isn’t that different to any other current high-end R9 2XX series GPU as it has Direct X 11.2 support, OpenGL 4.3 support and Mantle API support.


AMD says that upon launch there will be a wide selection of R9 270s available from its board partners, you can see those below.


The R9 270 will cost $179 which is $20 less than its bigger brother the R9 270X. If we compare the R9 270 to the pricing of the HD 7850 and HD 7870 when they launched, $249 and $349 respectively, we can see the R9 270 is a dramatically more affordable graphics card. The result is that consumers will be able to pick up the R9 270 for $179, which is cheaper than the HD 7870 GPU this is essentially based on (even taking into account current clearance pricing deals that can be had on HD 7870s).


ASUS’ packaging boasts that the Direct CU II OC version of the R9 270 is 20% cooler and 3X quieter than the reference AMD board and cooler design.

    Guys, i really want to know. Which card would be better the 7870 or the 270x? and are is it really worth paying 200 for the 270x instead of the 270? (with out ‘x’)?

    • In order of performance it goes 270x, 7870, 270 (if all at stock). Of course if you buy an overclocked 270 (like we reviewed) then its better than a stock 7870. You have to considering pricing at the moment goes (from expensive to lowest) 270x, 270, 7870. So by that logic the best value for money is the 7870 and the 270x/270 are joint. If you factory in overclocking value for money goes 7870, 270x and 270. Its a hard question to answer as they are all similar. If I had to choose I’d buy a HD 7870.

      • Nabeel Farooqui says:

        I was actually going for the 7870, until they released these GPUs, I’m only reconsidering because the 270 is newer and will be supported for a bit linger than the 7870 or the 7850. Its newer. Anyway, I’m already waiting a few months. Then we’ll see what happens.

    I’m thinking of buying this board.

    Not have an individual cooler for the memories VRAM is a long term problem? affect the longevity of the card?

  3. HERPIDY DERP says:

    I’m hoping power consumption was for the entire system… because if not those numbers are way to high.

  4. abrbabr says:

    great review, you helped me choose card

  5. Manitha Chandrasena says:

    i just bought this card and i plan oc it, i never oc before. The card has 1 6 pin connector which means the max power is 150 watt and the power consumption of the gpu is also 150w so you wouldn’t have enough room to overclock. i think i got something wrong but i dont know what

    • Kalan Petty says:

      Guru3d tested the R9 270 and found the card actually pulls about 143w. In this case you would have 7 watts of OC headroom.

  6. George says:

    Can I have 3 monitors running at the same time with this card? I’m looking to get 2 and put them in crossfire so I can get 6 monitors running at the same time, but not for gaming to be honest. Thank you.

    • chris robo says:

      yes, just remember you need an active display port not a passive display port for the 3rd monitor that you will use the display port for, i have used mine for quite some time with eyefinity and had no issues.
