Literally two-thirds of all general-purpose PC users use Intel integrated or motherboard graphics as a sole or primary video interface. I'm stunned there's that few complaints.

I bought a Haswell i3 for my HTPC and there is a bug/issue with the drivers that caused my CableCard delivered video to Windows Media Center to chug and black out and generally not work. I haven't tried it since because I bought an GTX 750 Ti for it, but it was annoying as gently caress.

I was looking at AMD APU video benchmarks. There doesn't seem to be a lot of gain since trinity. Has AMD stated they are only working on power consumption or did they realize killing off the low end card market was a bad idea?

With only dual-channel DDR3 to work with, they're pretty bottlenecked. Their low-end cards have far more memory bandwidth to work with.

I know there was a tenuous "Socket FM3" to go with Zen, but part of me wonders if AMD will say gently caress it and make the CPUs and APUs fit a G34 socket size if they adopt HBM L3 cache or something even more complex. Would this provide any advantage?

G34 has all those pins for extra memory slots + allowing CPU's to communicate, its not needed for HBM or any other on package memory really. Socket size isn't the limitation for HBM. Its price that could (probably will) kill the idea for low cost APU's which is the way AMD has to price them in order to sell them. Slapping HBM on their APU's might allow them to get mid-tier-ish GPU performance but also means they'll have to price them lots higher just to break even. WAG on my part here but $2-300 would probably be the price range of a 'high end' APU with a 1-2GB HBM cache on package via interposer. Even tied to Excavator CPU's the performance vs price wouldn't be bad but most enthusiasts, and those are the ones who'd be interested, probably wouldn't bother with it for that price. A low end Intel chip and a mid range dGPU would probably be better value over all even if it ends up costing a bit more. It sucks but I think they're stuck being bandwidth limited with their APU's for a long time.

PC LOAD LETTER posted:G34 has all those pins for extra memory slots + allowing CPU's to communicate, its not needed for HBM or any other on package memory really. I don't think so, not quite as much. We honestly don't know the pricing for HBM right now, but if I had to take a guess, its eventual pricing cannot be much more than mass-production GDDR5. If it isn't, it doesn't make sense to use it across an entire product line the way Nvidia wants to do with Pascal. Because that's that entire architecture's thing. I really do not think that it will cost anything remotely approaching Intel's 128 MB of eDRAM. A lot of the cost incurred there is due to the cost of the interconnect, something neatly dodged by how HBM is built from the ground up. Now, casual information that I have on bulk GDDR5 is from the BOM breakdown of the PS4, which then was said to be $110-$140 for the 8 GB of GDDR5. Per gig, that turns out to be $17.50. That's... not really that much. I feel that any increase in cost will be large enough to cover the cost of BOM + interposer + added complexity, but remain low enough to allow AMD to market the part to ultrabook makers. It's contingent on them that they get the pricing on this absolutely right. Pricing should come down even further with HBM2, which is slated to hit the market in 2016. Given that HBM just began sampling risk production back in... I want to say August? That's a phenomenally fast dev cycle for doubling capacity, which means that it must be something they were already cooking + die-shrink. And really, given that current Intel parts with onboard memory only have 128 MB, I think AMD stands to gain a lot more performance with the 1 GB minimum per stack.

Supposedly its not so much the memory costs that get you with HBM. Its the cost of the interposer, which is effectively a huge die IC fabbed on a 'coarser' process, plus the cost of assembly and testing. The interposer has to be gigantic since it sits under the die, Fiji has a rumored 550mm2 die while Carrizo has a ~250mm2 die size, and must be still big enough to allow the HBM memory packages to be mounted to it too. Smaller multi die interposers to bring down costs are something that is being worked on but I don't think its working outside of a lab yet. IIRC HBM2 is about giving you more bandwidth and/or RAM capacity and not necessarily bringing down costs. Depending on how they configure the GPU (ie. going all out for more bandwidth or RAM capacity) you might see costs go up or stay the same.

I was thinking simply that physical space might be a limiting factor for such a decision, not whether it was specifically a limitation on HBM. Thus the real challenge is trying to get a CPU with ~50-100$ performance without adding more than ~100$ to the total cost to justify it? If they can get Zen to have Skylake like performance (achievement in itself), I could see the costs being justified on A8 and A10 processors. Based on released information, maybe AMD does realize there might be a cost problem, hence the usage of ARM cores for the low end of Zen. A4 and A6 are ARM, A8 and A10 are x86? Maybe the replacement of the FX series are A6s and A10s with the GCN deactivated to give the processor cores unlimited access to the L3 cache?

The HBM packages themselves are tiny. About the size of a small pill, so size isn't an issue for putting them on a FM3 package. Stolen from this thread which BTW has tons of great info. and discussion on the subject about HBM and Fiji in general. It was other types of RAM that would've had possible packaging issues with FM3 due to size. I suppose they could've just left the pin out the same size and extended the package out to one side and plopped the RAM there if they really wanted to use something off the shelf and not do a custom RAM package. There is no indication that they ever wanted to go that route though. Zen we have hardly any information, branding or otherwise, at all on so only the most wild of WAG's are possible about it at this point. I would think if they can get near-Skylake performance at similar TDP they'll be thrilled. Skylake-ish performance with a significantly higher (10-25w) TDP is probably more realistic given the process and R&D disparity. I hope they can pull that off. If they do and they sell it for a bit less, like historically they did normally, it could be a successful chip. PC LOAD LETTER fucked around with this message at 16:06 on Feb 14, 2015 |

So even if they say, double the number of GCN cores, it'd still comfortably fit on the FM3 package? HBM and DDR4 potentially makes more than 8 GCN cores worth it, so maybe my poorly worded question is better put as "Would they go with a larger chip if the increased the number of GCN cores?" I wasn't arguing about the size of the HBM, SAD had corrected me earlier upthread. Still fascinating to read and learn. If they only manage a 10w disparity and close performance than it might start becoming a toss up between the two brands, especially if the Zen design shows a low level of maturity and they can eventually get more out of it.

Yea it'd probably fit. Even at 500mm2 the die would be still quite smaller than the package. Would they actually do that? I dunno. Kinda doubt it. That'd be an expensive die that they couldn't sell for a low price.

WCCFtech claims to have had "the chance to talk to a guy high up in the AMD supply chain", which they split into four parts: Part 1: About AMD sticking with 28nm. "Nolan APU is on the 28nm process ... it will only be a ‘mild’ update to the Beema/Mullins platform and be FP4 BGA packaged" Part 2: "AMD actually had a desktop Carrizo planned, something that was later canceled ... they decided to reiterate Kaveri with a refresh named Godavari. If they do decide to go forward with a Carrizo Desktop, it won’t arrive till H1 2016" Part 3: "Zen will be AMD’s focus for the duration of 2016 ... AMD will be releasing Zen for the server side first, then workstations and then HEDT (mainstream market)" Part 4: "[Intel] Skylake has something brand new – Intel keeping an above top secret attitude even after NDA ... Our source stated that he is fairly certain AMD knows about this ‘new’ feature and will try to incorporate it into Zen" And bonus WCCFT crap, just in case four helpings wasn't enough: Carrizo presentation leaked: "The die is still based on a 28nm node yet AMD has managed to optimize the overall chip design by adding 29% more transistors than Kaveri thanks to the high-density design library. This results in a 3.1 Billion transistor die that delivers 40% lesser power consumption and 23% lesser die area than its predecessor. The H.265 encode support allows 3.5 times transcode performance of Kaveri while the compute architecture enables the 8 GCN compute units (512 stream processors) a reduction of 20% in power consumption."

PSA, WCCFT can be full of crap, trust nothing unless you've got a second corroborating source other than the one that they list that has independently verified the story instead of just parroting. It's a good practice in general, but particularly pertinent for WCCFT. That aside, interesting to see that AMD is aping Intel by targetting servers and mobile, and letting binned parts flow to desktop. I think that's the best approach, and there's no shame in stealing a better way of doing things. Also, I'm pretty sure that AMD *tried* to make a MorphCore competitor.

Another design win for AMD. MediaTek is going to start licensing their graphics. http://www.fudzilla.com/news/graphics/37209-mediatek-to-license-amd-graphics I like to think that it must have been because AMD knows how to play nice with ARM on the same die. Should be interesting, though. AMD sold off Imageon for way too goddamn little to Qualcomm, which now forms the basis for their Adreno graphics. So technically, this is ATI vs. AMD. This, plus all the glNext getting rid of embedded OpenGL news should make things pretty interesting. SwissArmyDruid fucked around with this message at 06:30 on Mar 11, 2015 |

I wonder if this is more than a mere licensing deal? There is a lot of potential profit with some careful sharing of institutional knowledge. This might be what AMD needs for ARM Zen cores, a good step into the mobile market with their strongest foot, and this could give Mediatek the advantage to push an excellent midrange series of tablets, or even break into servers, laptops and desktops (pipedream?). Also, I would find it high comedy if AMD and Mediatek sometime in the future push Qualcomm to desperation, and suddenly there is an offer for 65 million dollars.

What I want to see, actually, is whether or not Vulkan can run on existing silicon, as DX12 will. That, I think, will be the biggest draw to widespread adoption beyond "we need a graphics API but we're not building for a Windows platform" Just as a purely scientific experiment, I'd love to see if any additional performance can be eked out of the PS4 using it, and then seeing how it stacks up a DX12-enabled Xbone.

NyxBiker posted:Is the AMD Opteron 4334 optimal for a small-medium web hosting company? (On a Dedi) There's no way it's optimal and I have doubts it's even acceptable. It's about half the per-core performance of an Intel Ivy Bridge Xeon, and there are now Haswell Xeons with solidly better performance per watt than Ivy. The scale-out prospects on an old AMD CPU are just awful. If you did Atom or ARM microservers you'd get far better performance per watt at a similar cost, with the downside of lower peak performance. And you could just keep some buff Xeon servers around for the relatively small number of heavy load customers, and they'd be the best of everything except for up-front hardware costs.

Similarly making special region-only games if there's not any local developers is just wasting a bunch of money if they don't sell.

For the console makers themselves, they typically run negative margins the first few years, which is made up for by a few game sales and the licensing fees charged to publishers. For the chip makers, well, AMD gets a flat license fee since they don't really own their own production lines for the console makers to buy from.
