    Thanks Ryan, this clears up a few misconceptions about kaveri overclocking, looks to be a decent 720p medium solution for budget gaming, I will advise not not to try and do what I did with a gen 1 apu, and that was overclock ram, apu cpu, gpu and a discrete gpu for an overclocked hybrid crossfire set up, did not work, even though I tried for around 3 months to get the system stable with everything overclocked.

      If you need 60 FPS+ then yes its good for 720p, if you’re happy with 30-40 FPS then I think we can say this is good for 1080p.It does of course vary by game and by the settings chosen. Yes with regards to what you’re saying I agree that’s why it didn’t work. When we increased the system base clock from 100 to 101+ MHz which overclocks the CPU and RAM by a tiny amount the whole system just collapsed. You can of course overclock the CPU through the multiplier which works but as we mentioned it results in reduced GPU performance. I think the key to the APU is in the GPU part, the CPU can be overclocked but it doesn’t reap huge returns and causes a lot more heat and power draw.

      • Derek Johnstone Macrae

        I really do think the faster that amd moves the apu chipset to ddr4, the better, your results clearly showed a huge gain when using faster ram, and overclocking the gpu on the apu was, in effect, the cherry on the icing, also, a move to a 1,000 shader core model would make 1080p at medium to high settings possible, I would love a high end single chip APU solution, and would be prepared to spend a lot on such a system, I am sure a lot of people would find that as attractive as I do.

          Excavator will have DDR-4 and AVX-2. Rumors also hint at a major redesign. It might be the next great AMD architecture.

          • Derek Johnstone Macrae

            thanks for the info Mike

            I had heard the same about the AMD Bulldozer, of how a great architecture would be, and it was a disappointment

          • Mike H

            That was from different management. It is clear that AMD is no longer moving in the direction of the original Bulldozer architecture. Comparing the 2 is like comparing the Intel that made Pentium to the Intel that made the core architecture.

          • BillyJ

            As opposed to Intel’s claims right? Sandy to Ivy to Haswell are pretty pathetic, certainly not leaps of any kind, granted, Intel had a good base to build on to begin with, they are quite non-revulutionary in any way…

            Same can be said for AMD, but in a different sense, their gains have been vastly bigger than Intel’s tick-toc BS, but then again, they started from a way worse base, also, for a lot of the improvements you need to pay a lot of attention to the details, which don’t always bring the end-results you would expect.

          • BillyJ

            Both of the first things you say are true, also, being 20nm, chances are they will be able to stick to the 65W TDP AND bring a sensible performance increase.

            However, I’m literally… praying for them to also consider a FX/APU hybrid line… as I know almost for a fact that new FXs in the classical sense won’t be seeing the light of day anymore… I would however love a 3-5 module APU w/ triple channel DDR4 and 768 ore more Pirate’s Islands GCN cores (to compete with Intel’s Socket 2011 or so… hence, TDPs up to 140-150W would be acceptable)… and for HSA to gain more traction…
            I also hope the new processes they will be made on allow for better clocking out of the box… OR some uber IPC increases at least… (or obviously, both, ha).

            Would love to see beastly FX-8900K run Crysis 3 on Medium 1920×1080 at 45+ fps and also keep up something like a i7-4930K in most x86 tasks… while obliterating it in hybrid compute ones…

          • Mike H

            Yea with Mantle and HSA and DDR4 an FX core like that would be enough to play Star Citizen fairly well for 300 or so dollars.

          • Blue Gum

            Excavator is DDR3.

      • BillyJ

        Not everyone played only the latest and “greatest” games you know… If you’re playing CS: Source or Mass Effect or Modern Warfare 2, I’m guessing you can get the 60fps 1920×1080 with minimal or no quality sacrifices at all.

  • Αντωνης

    So with higher DDR frequencies the CPU works much faster. The new APU looks good overall but certainly it is still weak for High-end gamers…

    • Peter Donnell

      You’re forgetting to factor price, any idiot can figure out that a more expensive product might perform better.

    • http://www.eteknix.com/ Ryan Martin

      Try playing games on a Core i7 4770K iGPU then come back to me and tell me it’s a better choice for high end gaming. If you’re suggesting that you would pair the Core i5 or Core i7 up with a discrete GPU (like a GTX 770 or R9 280X) then you’re completing missing the point of the APU. It’s a sub $180 “all in one” system chip, it isn’t meant to be for high end gaming nor is it meant to compete with the $240 i5 4670K or $330 i7 4770K. It is meant to be a convenient all in one solution.

      • BillyJ

        If AMD didn’t also make dGPUs, then I would say… yes AMD, please make even faster APUs, so they will take over ALL of the gaming and computing markets… but no, they also make THOSE. And I ask him, the person you also replied… why would AMD want to harm their own discrete graphics segment by making insanely fast APUs for “hardcore” gamers again?

        It’s fast and it will keep getting faster with every generation, but it’s fast within what it’s supposed to do, not what you think it should.

  • BillyJ

    Sooo… why not test with a DDR3-2666 kit or something? Didn’t you guys have one around or did the APU not like that speed for it’s IMC? Either way, yes, 2666MHz kits have a pretty huge premium when compared to 2133 and 2400 ones, but there’s at least a couple of them that aren’t an arm and a leg… Personally, I would have done that just for the heck of seeing how far can you go… and also, to confirm the “games need more bandwidth, compute workloads don’t, hence the biggest gains are in the compute tests” bit.

  • benchmarks_of_truth

    Have you tried overclocking the NB frequency to see if it has an effect on the iGPU’s gaming performance ?

  • ramonzarat

    Once properly overclocked to ~4.5Ghz on the CPU, ~1Ghz on the GPU and fitted with 2400Mhz RAM, it’s the perfect setup for 720P medium settings on the cheap. As of November 2014, I went on Newegg and was able to build a
    PC for 405$ US:

    Case: Any case at ~30$ will do. I found the Cougar Spike for 27$ with USB 3.0 ports!
    PSU: Brand name / 80 plus certification is a must. The EVGA 100-W1-0430-KR will do just fine especially at 15$ after rebate
    MB: Motherboard with 2400Mhz DDR3, USB3 and HDMI. The Asus A78M-E FM2+ at 49$ is perfect
    RAM: Cheapest 2400Mhz 8GB DDR3 kit. The Mushkin 997084 CL10 at 79$ will do
    CPU: Of course, the A10-7850K at 160$
    HD: Cheapest 1TB will do. The Western Digital blue WD10EZEX 7200 RPM at 55$ is fine
    Cooler: The best cooling/price ratio ever is still the Cooler Mater Hyper 212 plus at only 20$

    Total: 405$

    You might add a DVD burner for 20$ and a Radeon R7 250 to use in “dual graphic mode” to get 30-40% boost in FPS for 69$ ( GIGABYTE GV-R725OC-2GI REV2.0 )

    Total with option: 494$

    For under 500$, you can play all modern DX11 games at 720P/900P at medium settings and get mid 40s to low 50s FPS. The best part is you can upgrade this setup to a full blown R9 270 or a GTX 760 in a few years and practically double your score. If you would like to upgrade to a more powerful video card down the road, the 430 Watts PSU will not be enough, a 500/550 Watts model would be required.

    Why isn’t AMD making FX 6000/8000 series based on Steamroller is still beyond me.

    • Topias Olavi Salakka

      They’re creating an all-new architecture, better than Steamroller. I think it was called Zen.

      • Cryio

        FX 6300/8320/8350 are still great CPUs and great deals overall. Newer architecture and some or slightly higher prices would still sell like hotcakes.

        The FX 6300 is selling like crazy.

        • Topias Olavi Salakka

          Yep. I have an FX-8320 and works great.

          • Cryio

            I have a FX6300 and I couldn’t be happier as well.
