    You've landed on the AMD Portal on AnandTech. This section is sponsored by AMD. It features a collection of all of our independent AMD content, as well as Tweets & News from AMD directly. AMD will also be running a couple of huge giveaways here so check back for those.

Although AMD's second-generation mainstream APU platform, codename Trinity, launched months ago in notebooks the official desktop launch is today. Rumor has it that AMD purposefully delayed the desktop Trinity launch to clear out unsold Llano inventories in the channel. Although selling APUs in notebooks is pretty easy, convincing desktop users to forgo the discrete GPU option (and ignore Intel) has been a tough battle for AMD. I keep going back to two slides that show us where AMD wants to go and the cores it'll take to get there:

The ultimate goal is this beautiful cohesive operation between CPU and GPU on a single die. That future will require a lot of software support, not only at the application level but also at the OS level. And I'm not talking about Windows 8. We're still far away from this APU dominated future, but AMD is marching in that direction. The second slide shows the x86 cores that we'll see from AMD along the way. AMD is still playing catch-up in the x86 CPU space and it's got a lot of lost time to make up for. There's no hiding the fact this is going to be a multi-year effort to simply get close to Intel's single-threaded x86 performance. Through pricing, leveraging its GPU technology and throwing more transistors at the problem AMD can still deliver competitive solutions, but it's not going to be a walk in the park.

Last week we took a look at the GPU side of the desktop Trinity APUs. We looked at the top end 384-core Radeon HD 7660D configuration as well as the slightly slower 256-core Radeon HD 7560D GPU, both of which easily outperformed Intel's HD 4000 and HD 2500. As far as processor graphics go, Trinity on the desktop maintains a healthy lead over Intel. There's still a place for discrete GPUs but that's pretty much at the $100 and above price points.

Today we're able to talk about pricing and x86 CPU performance among other things. The good news on that front is the most expensive Trinity APU is fully unlocked and is priced at $122:

AMD Socket-FM2 Lineup
  Modules/Cores CPU Clock Base/Turbo L2 Cache GPU TDP Price
A10-5800K 2 / 4 3.8 / 4.2 GHz 4MB 384 cores @ 800MHz 100W $122
A10-5700 2 / 4 3.4 / 4.0 GHz 4MB 384 cores @ 760MHz 65W $122
A8-5600K 2 / 4 3.6 / 3.9 GHz 4MB 256 cores @ 760MHz 100W $101
A8-5500 2 / 4 3.2 / 3.7 GHz 4MB 256 cores @ 760MHz 65W $101
A6-5400K 1 / 2 3.6 / 3.8 GHz 1MB 192 cores @ 760MHz 65W $67
A4-5300 1 / 2 3.4 / 3.6 GHz 1MB 128 cores @ 724MHz 65W $53
Athlon X4 750K 2 / 4 3.4 / 4.0 GHz 4MB N/A 100W $81
Athlon X4 740 2 / 4 3.2 / 3.7 GHz 4MB N/A 65W $71

Compare this to Llano's launch where the top end SKU launched at $135 and you'll see that AMD is somewhat getting with the times. I would still like to see something closer to $100 for the A10-5800K, but I find that I'm usually asking for a better deal than what most CPU makers are willing to give me.

AMD's competitive target is Intel's newly released Ivy Bridge Core i3 processors. There are only five Core i3s on the market today, four of which use Intel's HD 2500 graphics. The cheapest of the lineup is the Core i3 3220 with two cores running at 3.3GHz for $125. Intel disables turbo and other features (there's effectively no overclocking on these parts), which AMD is attempting to exploit by pitting its Trinity K-series SKUs (fully unlocked) against them. AMD's TDPs are noticeably higher (100W for the higher end K-series parts compared to 55W for the Core i3s). Intel will easily maintain the power advantage as a result under both CPU and GPU load, although AMD's GPU does deliver more performance per watt. Power consumption is a major concern of AMD's at this point. Without a new process node to move to for a while, AMD is hoping to rely on some design tricks to improve things in the future.

At the low end of the stack there are also two Athlon X4s without any active GPU if you just want a traditional Trinity CPU.

The Test

This will be our last CPU/APU review on the current test platform/software configuration. The next major CPU review will see a move to a brand new testbed running Windows 8. As always you can get access to far more numbers than what we report here if you use our performance comparison engine: Bench. Of course if you want to see the GPU and GPU Compute performance of AMD's Trinity APU check out part one of our coverage.

    That's what they said about Trinity last year. I'm not buying it, not since Bulldozer. Reply

    Yep, it's always the future, the next one, for the amd fanboy Reply

    I agree, the best case scenario for AMD is the A10-5700 with 65 watt TDP in a SFF ITX enclosure utilizing the integrated GPU. Reply

    Oops that last line should read "That puts a $50 saving towards..." not $70

    So:
    - Pentium G850: $70 (HD2000 less Quicksync)
    - Gigabyte GA-B75M-D3V: $70 (with PCIe 3.0 and USB 3.0 onboard)

    Can easily upgrade to a more powerful GPU/ CPU down the line..

    Correction to your comment
    The G850 will only support PCIe 2.0, you would need to wait for Ivy refresh of celeron/pentium.

    If it was me and I was going cheap/Intel, I would just buy a Celeron G530 for $40, why bother with the G850, its just as handicapped with a little more CPU freq.

    But trinity would be a whole lot more fun to play with then those chips even though it may be slower doing a lot of the same task. Some of us just enjoy overclocking while undervolting while rooting for the perpetual underdog.

    The G850 has Intel HD 2000 graphics. Big step up. Also as far as motherboard compatibility, if you go with a celeron, your choices for boards that are also compatible with i3, i5, i7 boards is slim pickin's. Going with a pentium gives you more advanced motherboard options. I agree that the G530 is a great CPU for cheap but it's just a little harder to upgrade to anything amazing. Trinity is quite interesting though. Would be great in a small desktop for the wife. Reply

    HD 2000 is a scrap ;) Reply

    Having Intel graphics is not, in any way, a plus. Especially a turd like HD2000. Reply

    how is the ivy bridge pentiums or celerons going to have pci express 3.0 when even the core i-3 processors don't? intel decided to omit pci express 3.0 from everything under an core i5.

    the only thing besides a slightly better clock for clock that ivy gives you with the ivy bridge pentiums is memory support up to speeds of 1600 instead of 1333 like sandy bridge.

    also forgot to mention that one ivy bridge pentium has been out for a while now. the G2120. it is retailing for $100 on newegg. Reply
