AMD Kaveri

If you follow our website and the technology industry more broadly then you may have heard a lot about Kaveri since it was officially launched on January 14th 2014. Kaveri is the codename for AMD’s fourth generation of desktop APU (Accelerated Processing Unit) after Llano, Trinity and Richland. In successive generations we have seen AMD’s APUs grow a lot stronger mainly in terms of graphics performance but also bringing refinements in terms of power consumption and CPU performance as well as new features.

So what does Kaveri bring to the table that is new? In terms of new architectures we see a transition from Piledriver (Trinity) to Steamroller on the CPU side and from VLIW4 (Trinity) to GCN 1.0 on the GPU side. Yet the most exciting and easily the most talked about new feature is the inclusion of AMD’s new HSA technology. HSA is AMD’s “Heterogeneous Computing” plan which includes two main components: hUMA (Heterogeneous Unified Memory Architecture) and hQ (Heterogeneous Queuing). hUMA allows for the sharing of system memory equally between GPU cores and CPU cores and hQ allows for both the CPU and GPU cores to independently schedule tasks.


There is of course more to Kaveri than Steamroller, GCN and HSA – but those are the main components. Other new additions include full support for AMD’s TrueAudio technology, Mantle support and an improved Unified Video Decoder and Video Compression Engine. However, before we delve into those new technical improvements and features, let’s first discuss what this article is all about.

Today we are examining AMD’s entire new range of Kaveri Desktop APUs – the A10-7850K, A10-7700K and A8-7600. In addition we will be comparing those to their equivalents from the last generation – the A10-6800K, A10-6790K and A8-6500T respectively. Then for a bit of perspective we are comparing those three parts with their main Intel rivals – the Core i3 4330 and Core i5 4440. What we’re looking to do is provide a complete perspective on how AMD and Intel’s offerings match up across a wide range of CPU, GPU and combined benchmarks covering areas like gaming, productivity and general system performance, as well as the generational changes Kaveri offer over Richland. Below you can see a summary of all the contenders in this comparison. Please note that the number of GPU cores are not comparable between all processors below, but are only for reference. GCN cores are much more powerful than VLIW4 cores while Intel’s “cores” work in a different way, they are technically “execution units” not cores.

    may as well brand the A10 as the 720p chip, if your happy to game at that rez, still waiting for a capable APU that can play games at 1080p, the 512 cores just isn’t enough on its own, the chip needs around 650-1,000 cores, also, ram speed is critical for future apu performance, the quicker amd move to a ddr4 chipset, the better

    • Yes RAM is critical! We will be adding more about RAM with our RAM scaling featured coming up. Watch this space 🙂

      • Derek Johnstone Macrae says:

        excellent, also, love the way which the article summed up the cost of cpu+gpu V apu, it hits the nail on the head why you should buy an apu, however, I feel that AMD are missing trick here, a 1000 core apu with ddr4 support would allow many to build a slim steam machine that could compete with the consoles, as it is, you still need a gpu to provide an apu system with playable frame rates at 1080p, and overclocking an apu with a discrete gpu is no easy task, hybrid crossfire gives an apu system a much needed boost, as does ram speed, but it still leaves a lot to be desired, and the cost of a crossfired apu system v performance from an i5+discrete gpu puts many off, AMD need to make a huge leap in performance for the apu’s, I know why these chips are aimed at the budget segment, its to stop Intel grabbing market share, plus, a more powerful apu would probably eat into AMD’s own gpu business, I wish they showed more courage, and give us the one chip solution that the APU’s originally promised…

        • Derek Johnstone Macrae says:

          Could you maybe look at crossfire performance for the A10 ?…..can you get smooth 1080p gameplay ?, and is the cost V performance worth it ?

          • I am currently doing hybrid crossfire testing right now. Will also be doing overclocking and the RAM scaling I mentioned. We just wanted to get the base review out first. We will be adding the other bits over the coming week or so.

          • Derek Johnstone Macrae says:

            more tech goodness, thats great Ryan, cheers

    • Streetguru says:

      1600x900p is the sweet spot for APUs right now.

    DONT THINK ITS MADE FOR GAMERS… but for people who game on facebook pogo nad things like that will be fine

  3. Acidz says:

    i seen a demo of the kaveri APu playing Battlefeild 4 on 720p with medium details it hand handle some games pretty well

  4. Marcus Ellwood says:

    I hate to say this, but even though I am a part of the kaveri’s intended market (which is *poor* entry level gamers and HTPC users), I don’t see why you would buy one. The Richland 6800k does comparably well to the 7700K but costs $30 less. I’m a poor gamer so that $30 does mean something to me. With the Kaveri’s dual graphics not coming anywhere close to the performance of the $120 260x, The new APUs don’t even make sense in the long run because you might as well pay for a 260x instead of spending that money on the 250 or 240. Power consumption vs. performance only improved significantly on the 7600, but that hasn’t released yet so the kaveri doesn’t really win in any case.

    • Marcus Ellwood says:

      Well, I stand corrected on 3 issues so I guess I’m not really an expert like I thought I was. At first I didn’t see the power consumption chart on page 12, where both of the Kaveris in dual graphics mode beat the 6800k in power efficiency. I simply went by the TDP of the APUs (which dropped by 5W between generations). Then, I saw Newegg has $150 7700ks, so the margin between it and the Richland is now $20. Lastly, I learned that the Richland APU is really just an overclocked Trinity ($120), so the margin is still $30. Oh well, i guess I’m saving $10 because the power consumption doesn’t matter to me whatsoever.

  5. HMan2828 . says:

    As a reference, to convert a thermal margin to a processor temperature, you take the processor’s rated TDP and substract the thermal margin. So for a processor with a 95C TDP, the margins you posted are roughly equivalent to the temperatures measured. 95 – 57.9 = 37.1C for an A10-7800K at load. I think the reason they cannot specify the temperatures is because the TDP is configurable on those chips. Also keep in mind the temperature will likely rise dramatically with the GPU also on full load, because they both use the same cooling device. The stock fan will probably not handle the CPU and GPU at full load in turbo mode for too long, so I wouldnt cheap out on the cooler on these things.

  6. Albert89 says:

    Well this would have to be one (& only) of the most honest reviews about AMD ‘s Kaveri.
    And with all the bias against AMD, its about time someone did a solid review about it’s latest APU.
    Showing it to be a performer that exceeds all expectations with built in technology that’s starting to show even greater promise.

  7. Justin Downer says:

    You forgot about ram speeds with a Pentium+250X you only need 1333mhz ram vs the high speed ram for the APU’s plus you forgot about the differences in performance from DDR3 to GDDR5 on the 250X

  8. Dr. NEGA says:

    just add 4 more cores then it beat haswell 4 cores but amd is doing the mainstream architure tweak first then release to FX version last if proves it can hurt haswell 8 cores monster..and steamroller is not it but its huge improvenment than piledriver in 4 cores alone….the last generation excavator is the fix and improve version of bulldozer..and 8 cores can mess intel haswell-e very well at the end even it took them awhile to come around from the back of intel …since carrizo apu has 4 way l1 data and 3 way l1 inst. code its only 3 modules with 6 cores total and 20nm is very small and less power than haswell-e………combined with a dual carrizo with 8-way l1 data, 6-way l1 inst. code total in last FX version with it can fit up 3-6 modules in that processor with 6 and 12 cores from 95 watts to 125 watts and 220 watts for 4.0ghz to 5ghz…

  9. rs says:

    “In terms of temperatures with Kaveri it isn’t possible to judge. The temperature readouts on the Kaveri APUs are totally “borked” and the motherboard sensor readouts give ridiculously low temperatures which cannot be accurate – 37 degrees at full load for the A10-7850K? I think not.”

    But you think that Haswell processors need more than 10W less at idle because of “the incredibly power frugal nature of the Haswell design and the advanced idle sleep states.”? Really funny. Dear author, please always try to use your brain. The difference between AMD and Intel at idle is hardly measurable because both need only a few watts then (normally less than 5W). It should be clear that a difference of 10W or more is only possible if the motherboards draw different amounts of power. Or do you think every motherboard draws the exact same amount of power, regardless of the processor?

    Pure idle comparisons mostly don’t make much sense nowadays due to very advanced power saving mechanisms. We don’t have P4s anymore which really could draw a lot of power at idle. At least as long as you can’t guarantee the same power draw of the motherboards you won’t get meaningful values to compare.

    Nice review!.
    the concept of APU for gaming maybe didn’t look that interesting for western buyers where you could get better price/performance with separate CPU+GPU combo, but please don’t forget us that live at third world country where the price of an i5 is more than minimum wages in many parts of our country. With that in context, the A8-7600 combined with “Steam Sales” surely the best option for people who want enter the The Glorious PC Gaming Master Race at budget. and don’t forget the low power consumption too.

    yeah, i know i’m late into this.

  11. Ross McIvor says:

    It is quite interesting when you consider it is a CPU with a GPU integrated onto the Processor Die. I am currently Running an AMD FX-8300 @4.1GHZ. My Daughter is running on an AMD A6-6400 at 3.8GHZ dual core with 8GB 2133MHZ RAM. Performance wise, SHe can run World of Warcraft on Medium settings at 40FPS easy and watch youtube videos in the background. With her only being young I am not going to spend a fortune on her first PC. These AMD APU’s are perfect and hit the right spot in bang for buck. people always tell me “for £100 more you could have had an Intel I7 4790k instead of the FX-8350” but in doing some research the AMD FX-8350 gave me the best bang for buck coupled with the R9 270X 2GB card

  12. BongCastaneda says:

    i was looking at my country’s local pc stores for the 480 amd vc which is supposedly 225 USD for the 8gb version but i was shocked to find it sellin 50% higher than the recommended price. then i compared prices of low to midend video cards to their US counterparts and i was saddened to see the same 50% markup from the recommended prices in the USA.

    No wonder a lot of people here are just depending on IGP and APUS to play their games.
    I settled for the AMD 7890k and got my self 16gb of memory since i cant get a price performance ratio for an intel cpu plus graphics card (overpriced in my country) that is equal to what other countries get.
    The 7890k turned out to be the best option for me.
