AMD Launches New Mobile APU Lineup, Kabini Gets Tested

An anonymous reader writes "While everyone was glued to the Xbox One announcement, Nvidia GeForce GTX 780 launch, and Intel's pre-Haswell frenzy, it seems that AMD's launch was overlooked. On Wednesday, AMD launched its latest line of mobile APUs, codenamed Temash, Kabini, and Richland. Temash is targeted towards smaller touchscreen-based devices such as tablets and the various Windows 8 hybrid devices, and comes in dual-core A4 and A6 flavors. Kabini chips are intended for the low-end notebook market, and come in quad-core A4 and A6 models along with a dual-core E2. Richland includes quad-core A8 and A10 models, and is meant for higher-end notebooks — MSI is already on-board for the A10-5750M in their GX series of gaming notebooks. All three new APUs feature AMD HD 8000-series graphics. Tom's Hardware got a prototype notebook featuring the new quad-core A4-5000 with Radeon HD 8300 graphics, and benchmarked it versus a Pentium B960-based Acer Aspire V3 and a Core-i3-based HP Pavillion Sleekbook 15. While Kabini proves more efficient, and features more powerful graphics than the Pentium, it comes up short in CPU-heavy tasks. What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU."

      While that might be great for GP-GPU I really don't see how useful that is gonna be for gaming. As for the Xbox One I think Angry Joe nailed it when he said that MSFT has lost their way, hell he said they spent more at their little "unveiling event" talking about fucking TV shows and cell phone style apps running on the thing than they actually did about the games. Considering it looks like ALL used games WILL be locked behind a paywall AND the thing won't even work at all if it can't "phone home" every 24 hours? Yeah all Sony is gonna have to do is say "We don't have that" and they won the next console war.

      The problem with AMD is NOT the memory, its NOT the GPUs, and this is coming from somebody that has built AMD exclusively in my shop for 5 years so I want to see the company do better but its the CPUs that are the problem. I mean it should be PAINFULLY obvious to everyone by now that the "half core" design was a major misstep but instead of accepting that and going back to the drawing board like Intel did when stuck with netburst AMD seems to be going full fail ahead and the numbers show that this approach? it just doesn't work well for the kinds of loads a typical consumer has, it works even less well for gamers which is why I've been having onto my Phenom II Hexacore for so long, because Bulldozer and Piledriver just suck.

      But even more puzzling to me is why both MSFT and Sony picked the absolute WEAKEST CHIP that AMD sells for their flagships...what the fuck? For those that don't know AMD Jaguar is the next release of the line that started with Bobcat...a chip designed to compete with ATOM on price and power. Its a MUCH simpler design and is really built about being "good enough" while giving you decent battery life and you are gonna use THAT in a next gen console that is supposed to bring all the next gen physics and particle effects that need serious number crunching power... a netbook chip?

      I have a feeling it won't take developers even 2 years to max out these consoles NOT because its running AMD but because they really picked the wrong chip for the job. It would be like bragging about your new gaming rig powered by the latest Intel Atom CPU...I don't care how you slice up the memory its still gonna be seriously bottlenecked thanks to the CPU.

      Because of exactly what parent said:
      AMD can provide unified memory (hUMA) with a decent GPU and a decent CPU on the same die. Intel cannot, nvidia cannot.
      hUMA will not make your PC faster in general, but it will provide you with a feature, even a PC with 20 Geforce Titans does not have: Latency free data exchange between CPU and GPU.

      It will make GPU processing more feasible especially on a small scale. I can't give you an example from gaming, but I can give you an example from my own expertise. When we simulate big proteins, we do it on a GPU. However, for small proteins, the latency overhead simply kills us. Processing on the GPU would be faster, but we need to copy back and forth all the time. We don't need faster GPUs, we need faster transfers. With hUMA: no problem.

    4. Re:hUMA by VortexCortex · · Score: 4, Informative

      I can give you an example in gaming: TWICE THE WORLD GEOMETRY. The data has to be loaded from persistent storage or network into main RAM, then that same exact data must be shoved over into the GPU in batches to be rendered on demand. With hUMA I don't have to have a copy on the GPU and a copy in main memory -- just one copy. That means TWICE the geometry with the same amount of total RAM.

      Furthermore, physics is great on the GPU I can parallelize the hell out of that. However, triggering sound effects and updating network state via read-back buffer is a horrible slow hack. hUMA means the GPU can actually be used to update gamestate that actually matters -- instead of just non-gameplay affecting things like particle effects. Logic can be triggered much more easily and course grain physics data can be read back at will for network synchronization. Client side prediction (latency compensation) also becomes a lot cheaper.

      I can get a crap load of fine structural detail rendering and acting to physics right now on discrete GPUs, but the problem is when I want any of that to actually mean anything in terms of gameplay, I have to read back the data to the CPU side. hUMA utterly destroys the barriers preventing all sorts of RAM intensive gameplay. Hell, even weighted logic trees for AI can be processed on the GPU instead of only on the CPU, and we'll have the RAM budget to spare because we don't need two copies of EVERYTHING in memory all of a sudden. That means larger more complex (read: smarter) AI, and lots more of them.

      Folks really don't realize how horrible the current bottleneck is. You want world that's fully destructible down to the pixel (atomic voxel), with models that actually have meat under the skin, and rebar in the walls, and with different physical properties so that you can freeze a door then shatter it, or pour corrosive acid on the hinge or create reactive armored structures on the fly by throwing some metal plate atop explosives atop the concrete bunker... Yeah, we can do all that on the GPU right now. However, without hUMA, on the CPU logic side of things the GPU is seen as a huge powerful black box -- We put the equations and bits of inputs in, amazing stuff happens, but we can't actually tell what's going on except for through a very tiny output signal -- the RAM transfer bottleneck; So, we can't really act on all the cool stuff going on. Right now that means we have to just make all the cool GPU stuff not important for gameplay, like embers that burn and blow about but can't burn you, or drapes that flutter in the breeze but can't be used to strangle someone with, or tied together to make an escape rope; Unless we planned all that out in advance.

    So AMD says, but Tom's Hardware disagrees:

    So what about the Core i3-3217U, a 17 W processor? Surely that one is a more virile competitor, and not much more expensive than the Pentium. Core i3's on-die HD Graphics 4000 engine with its 16 EUs stomps all over the A4's 128 ALUs, despite the backing of AMD's capable Graphics Core Next architecture. Now, AMD claims that Kabini isn't meant to go up against Core i3. But we found notebooks with this exact CPU selling for as little as $360 on Newegg. It may turn out that the free market doesn't let AMD choose which Intel-based platforms its Kabini-based APUs contend with.

    The cheapest laptop newegg sells that I could find was $250, so there's a good $100 range where Atoms, Celerons, Pentiums and AMD is battling it out - that's not much, really.

    Which is likely the part that matters in these laptops. I mean if you're trying to use these for serious number crunching you are using the wrong tool for the job. It's not like the single threaded performance is poor, it is horrible. Anandtech compared it to a i7-3517U, which is totally unfair price-wise (it's a $350 chip) but fair power-wise (it's a 17W chip). In cinebench single-threaded the Intel chip scored 1.24, the A4-5000 0.39 - that's a 3.18x performance lead with 2W higher TDP, 2.8x if you scale it to be equal. You're getting a not-quite-as-dog-slow-as-an-Atom ultra mobile laptop, but you're not getting anything fighting above it's league either.

    You missread his post.

    Your failure to understand the argument does not constitute a failure on my part to comprehend his comment.

    He was asserting that single threaded performance is what matters on these laptops, because no one is going to use them for big number crunching tasks that can actually use multiple cores effectively. He's correct.

    No, he's complextely wrong. What do you imagine that typical users need single-thread performance for? Most users need this only for games, and poorly-written ones to boot. PC games which require single-thread processing power are now vanishingly rare thanks at least in part to the influence of the tri-core Xbox 360, and the overwhelming tide of console to PC ports. Everything else the user typically does which requires very much CPU is already multithreaded. Most things the user does require virtually no CPU.

    Running a GUI, editing files, I literally did these things on machines with single-digit MHz speeds which, when they were less responsive than using applications of today, were only so because of disk access times. And these tasks are today multithreaded, because they are based upon multithreaded libraries. Take a look at the programs running on a typical windows machine today, virtually all of them have a crapload of threads. Windows makes thread creation cheap in the way that Unix makes process creation cheap... not least because Windows is heavily multithreaded itself. And we are talking about what the majority of users will do with this hardware, which means running windows, playing the occasional game, watching cat videos on youtube.

    Aside from games, the only times that most users use much CPU is during video encoding or possibly decoding, both of which are aggressively multithreaded and often even GPU accelerated, or while using graphics or video editing applications which are also typically heavily multithreaded, and have been for years. In short, practically no typical user actually needs serious single thread performance any more — what they need is good multithreaded performance, so that their computer can do a million pointless things behind the scenes without causing their cat videos to skip.

    The Pentium beats the Brazos at single threaded performance, therefore, is a better chip for this kind of task.

    The Pentium is only better than the new AMD cores we're talking about at the kind of task that people who buy APUs don't do. Thus, while your statement is factual, it is also irrelevant.

In short, practically no typical user actually needs serious single thread performance any more — what they need is good multithreaded performance, so that their computer can do a million pointless things behind the scenes without causing their cat videos to skip.

    I would go one step further and say that the majority of users need neither better single-threaded performance nor better multi-threaded performance. They just need newer hardware that isn't on its last leg.

    Beyond the first two or three cores, throwing additional cores at the problem provides little benefit for basic tasks. Video decoding might be multithreaded, but it is usually not massively multithreaded. At best, most of the decoding software I've worked with uses one thread to decompress and a second thread to deinterlace, so you're unlikely to use more than two cores total, in my experience, with the exception of the tiny trickle of CPU power required to fetch the data over the network or from disk in the first place.

    And good app responsiveness typically requires only two cores, give or take—one to offload the minor background tasks so that they don't get backed up too far behind the foreground processing and one to handle the foreground app's processing needs. Beyond two cores, the benefits start to fall off pretty rapidly. I can perceive very little difference in responsiveness between my current-generation MacBook Pro (4-core 2.7 GHz Core i7) and my circa 2007 black MacBook (2-core 2.16 GHz Core 2 Duo) except in CPU-hungry apps like Photoshop. Once you get past four cores or so, the only benefit is for people running massively multithreaded tasks, which isn't typical end-user stuff by any stretch of the imagination.

    The big difference that faster single-core performance gets you, assuming all other things are equal, is better battery life—being able to crank through the background tasks in less time means the CPU is idle longer. So more single-threaded performance per watt is a big win over more multi-threaded performance per watt because the former is more likely to result in power savings.
