AMD Radeon R9 270X GPU Overclocking

To take a quick look at overclocking we fired up AMD Catalyst Control Center and used AMD Overdrive to overclock these two Radeon R9 270X 2GB video cards.

270x-ccc

The AMD Radeon R9 270X 2GB comes clocked at 1050MHz on the core and 1400MHz on the memory. You can go up to 1400MHz on the core and 1625MHz on the memory in AMD OverDrive.

We were easily able to overclock the AMD Radeon R9 270X to 1205MHz on the core and 1625MHz on the memory. The limit in AMD OverDrive is 1625MHz on the memory, so we might be limited by the utility on this clock speed.  Let’s take a look at some Futuremark 3DMark scores with the Fire Strike Extreme preset to see what happens with performance when the card is overclocked.

270x-3dmark-oc

With this overclock we ran a quick run of 3DMark Fire Strike Extreme and found our score went up from 2,740 3DMarks to 3,110 3DMarks, which is an improvement of 370 3DMarks or 13.5%. This is a solid overclock, but what can the Sapphire Toxic R9 270X overclock to?

trixx-oc-utility

To overclock the Sapphire Toxic R9 270X video card we used Sapphire’s TRIXX overclocking utility. We were sent TRIXX v4.6.3 beta to try out and it appeared to work fine.  This utility goes way beyond the clock settings found in AMD OverDrive, so it will be interesting to see how far we can push this card. We were a bit dissapointed to find that the GPU Voltage (VDDC) was already set to the max by default, so all we could adjust was the GPU and memory clock speeeds.

After playing around for a couple hours and crashing the system a dozen times with failed overclocks, we were able to get 1260MHz on the core and 1652MHz on the memory (6608MHz Effective). This is 55MHz higher on the core that we could get from the reference card. This isn’t much higher than the reference card and guess what?  We’ve gotten slightly higher overclocks on AMD Radeon 7870 GHz Edition cards in the past when it comes to GPU clock speeds!   Our 3Dmark Fire Strike Extreme score went from 2,994 to 3,191 with this overclock.  The performance gap when overclocked is under three percent between the two cards.

    Looks like the card can be 3 or 4 crossfire it ?

  • CuriousAboutVDDC

    Hello guys, a quick question here.
    It’s mentioned in the reviews that the Sapphire Toxic R9 270X GPU Voltage VDDC is already set to max at default in the Trixx utilities.
    Does it means that it is indeed at it’s max limit of voltage or is it just software configuration and that the GPU can actually take in more ?
    Would it be possible that in future software uptes or through other software that we can meddle with the GPU voltage and maybe push the Clock speed and Memory speed a lil bit higher ?

    Much ado about nothing. So a little price cut will be forthcoming. WoW 50bucks. I’m going to fill up my gas tank, halfway.

  • Lazy too

    Just ordered a Sapphire Dual-X R9 270X and Ill be happily gaming on Tuesday. Abot time I replaced my old 5850. I dont bother with nvidia anymore, their stuff is way overpriced.

    • rishi dev

      You know what, i always bought AMD no matter the price.

      But AMD partners along with retailers have a monopoly over world market in Europe and Asia. Which means i cant afford to buy AMD anymore!!!! A $199 US listing translates to a $260 in major markets across Asia. Which means i can buy 2 gtx 650ti BOOST for less than a single 7950. Although i dont want to, im forced. A pathetic 7790 is at the same price point as the BOOST. The 650ti boost manages to level or surpass a 7870 in some games.

      I dont know why this is so. Maybe because AMD gpus have better gpgpu code and hardware; to offload intense CPU loads. For now HSA and GCN are oblivious. Those who dont know the GTX 700 have crippled opencl and opengl performance, not much but a significant bit less.

        any opengl tests out there? like rage from id software?

        wtf? a 650 ti boost doesnt beat a 7870, not even a 7850.

        • Ko zhi yi

          A 650 Ti Boost is equal to HD 7850. The test in Techpowerup that says the 650 Ti Boost is better than HD 7850 by a mile is heavily biased because it includes the StarCraft II benchmark. StarCraft II benchmark heavily bias NVIDIA cards. The heck, a regular 650 Ti (not boost) beats HD 7870 @ 1920×1080 in SC2

      • CuriousAboutVDDC

        Strange enough. In my part of Asia, nVidia cards are priced more expensive than the AMD cards.
        In my country, GTX 660 Ti is about the price of R9 280X.

    • Ko zhi yi

      Cheapest NVIDIA GTX 770 in my store also RM1399, but Sapphire Vapor-X R9 280X costs RM1229, yet it performs as good as the GTX 770.

      • KStream

        Not really. Any of the OC:d GTX 760′s perform aprox 10% better

        • Ko zhi yi

          OC’d GTX 760 = GTX 670. I should bought the 760 (RM939) but R9 280x DUal-X now costs only RM1099 in Malaysia

  • basroil

    Pretty much how I called it, Nvidia did a very smooth move cutting the price of only the 600 series cards while keeping the 700 series at standard price. The R-200 series cards based on the old architectures just were too overhyped, and the only thing that can even challenge nvidia’s higher range price:performace will be the 290x

    • Thermogenin

      It will do more than just challenge the 780 GTX=)

      • azbest

        hopefully they repaired the power consumption on the chip. they should really work hard to produce chips with better asic rating.

    • blablabla

      too lazy to sign in, but actually AMD& Nvidia are moving in lock step. Both rebranded old cards, both only introduced 2 new high end cards. But AMD actually introduced 3 new cards if the 7790 is counted, and slashed prices to boot. Why so much AMD hate?

      • azbest

        because of the high power consumption :)

      • basroil

        Nobody is hating on AMD, I actually alternate between the two companies (Geforce 440Ti then Radeon 9600 then Geforce 7200(go) then HD4850 then Geforce 425m, and then a 560Ti) for my primary computers. I just don’t care for the hype they made for the R260-280x. The GTX 770/760 weren’t special either, but at least Nvidia didn’t go showboating (like they did with the 780). So far the R290x seems to be a decent card for decent price, and might live up to the hype if it’s priced lower than the 780.
