I think I remember someone saying that AMD wasn't planning on going nuts with APUs? AMD disagrees http://wccftech.com/amd-exascale-heterogeneous-processor-ehp-apu-32-zen-cores-hbm2/. I think the biggest take away is that the design still seems modular and can scale further up. But 32GB HBM2 seems insane unless that's something akin to a Fiji or Grenada sitting in the center there, and even then. IIRC, AMD intends to release server processors first, followed by mainstream APUs, and low end APUs (Construction cores) to get volume up on AM4 support, releasing Zen in Q3. This means Greenland has to be released a bit prior to Q2 if server chips are going feature Greenland. Can someone remind me what events AMD could use for public launching in Q1?

That lines up with my pipe-dream for Zen. Cut it down to 8 cores and 8gigs of HBM w/ integrated greenland graphics and you theoretically don't need any additional system ram. Just pop a M2 SSD on there and you have something that's the footprint of a NUC (plus a huge heatsink) that should be all you need for 1080p gaming. Or get real crazy and give us a mitx board that's just 4 sockets for APUs that can be crossfired together. Give us something to actually justify those 1.2Kw power supplies. But like it said Pipe-Dream.

Oh look. It's an HBM-enabled APU. (for HPC servers, but.) http://www.bitsandchips.it/9-hardware/5858-amd-exascale-heterogeneous-processor I am slightly concerned how the Intel/Micron crosspoint memory announcement was timed, though. If we're accelerating work on large data sets by making the storage medium fast enough to allow direct manipulation while bypassing traditional memory, it could make the idea of bringing GPU compute and memory onto the CPU die the final too-little, too-late entry in AMD's wikipedia page.

Anime Schoolgirl posted:I'd wager this was part of the reason of the development of HBM in the first place. This isn't going to come to desktop-class APUs in the near future. Especially not the interconnect. There's no way it's even in servers in less than 2 years. Knight's Landing is going to hit first and it's going to hit harder. It's the same idea except hitting in the range of 64 cores cores per processor (each quad-threaded), and with a couple generations of in-house development from a company that owns its own fabs that are more advanced than those publically available.

would take 4 to 5 years and $1.5B+ in R&D to ship something like that, since you're basically talking about coupling two vastly different processors at a level far beyond anything that exists today (actual shared MMU which is a new level of synchronization hell that no one is prepared to deal with), an entirely new interconnect, far better ECC/reliability functionality than exists on any GPU today, and complete rewrites of every software package that these exascale sites care about (plus all of the required driver/OS/networking stack bits). it's also something of a niche product--I don't think this is a great design for anything that doesn't require strong scaling, as your node throughput is going to be fixed and so you have a fixed ratio of nodes to networking gear, even in problem domains where you want the fattest nodes possible. (you know, deep learning) fake edit: I actually glanced over the AMD paper after writing the above, and they briefly touch on all of these concerns. the SW concerns are blown off with "eh HSA will handle it! it's open, everybody will be using it by then!" like every other AMD document ever produced, the RAS concerns are "oh yeah we figure that out huh," no mention of an MPI replacement or something that works better than MPI for so many nodes, et al. in other words, don't get your hopes up, pals, this is a fluff piece. it's exactly as fluffy as the NVIDIA SC10 preso that laid out "Echelon," their exascale processor. and shocking! it basically says exactly the same stuff.

So if any of you have AMD's marketing team sending you spam, they're offering the FX-6300 for less than $90 with rebates.  I guess if you need a new space heater that can (almost) do 4K-to-VP9 video things for you at a somewhat slower-than-reasonable clip, there's that. They also have their friends at Newegg selling FX-9530s at fire sale prices, if you want a more expensive space heater.

It looks like it's slower than an i3-3220 even at video encoding. http://www.anandtech.com/show/6396/the-vishera-review-amd-fx8350-fx8320-fx6300-and-fx4300-tested/3

Does that still hold true in hardware-assisted encoding? As always, I'm gonna throw the G3258's lack of AES-NI out there. If you're doing lots of SSL or using software-based full-disk encryption it could make a difference.

And for general home use a G3258 is really hard to beat for the money. It's not that great for beefy stuff like media encoding, but that fucker overclocks like crazy, on a per-core basis it can usually keep up with a 4770K in games. Used to be that you could pick it up with a Z97 board at Microcenter for $100 before tax and before a $10 rebate. Can't argue with that. You can still get pretty close to that if you're willing to take open-box gear. The one place I think AES-NI probably makes a big difference is software-based disk encryption. If you don't have encryption at the SSD controller level then AES-NI will greatly soften the performance hit. I don't quite get why more people don't use whole-disk encryption on laptops - nowadays everyone uses whole-device encryption on their phones, why not laptops too? I actually run an Athlon 5350 in my home media server. It's not going to break any speed records but it's about as fast as the Intel equivalent (J1900) and it includes AES-NI while the Intel doesn't. I'm pretty satisfied with it for what it does and I'd recommend it for that (note: I've never tried transcoding on it). An APU in a laptop is pretty ok at gaming for the market segment they're in, a discrete GPU wrecks their poo poo of course but the alternative for most people is probably another iGPU. Other than that - yeah, not a whole lot to recommend. Paul MaudDib fucked around with this message at 00:31 on Aug 7, 2015 |

I haven't tried multiple streams, but I suspect it will struggle with two or more HD streams. In general, the 5350 makes a pretty good home server setup for Plex or a basic web server.

I believe they originally launched at close to 1000 dollars as they were intended to be AMD trying to cater to the premium enthusiast crowd. Turns out the premium enthusiast crowd isn't stupid enough to spend that kind of cash on an AMD CPU. I think it dropped to Core i7 prices soon after and now is cheaper than a Core i5.

Most AMD boards that aren't $200 don't even have the VRMs to handle that CPU, so the 'value' of the chip's even worse when you factor in board costs and additional cooling on top of the already-insane power requirements. No one should have to have separate VRM and rear-socket fans just to run their desktop but that seems to be the recommended options in dwindling AMD sections on hardware forums. Even taking AMD's desperation into account it's mad to think that someone in their company thought a halo-tier CPU for almost 1K would sell when the competition destroys it with none of the downsides. Maybe if it's really cold outside and you don't pay for power..

Both have access to mini itx and the A6 has more oopmh behind it, but is that extra capability not worth the +50$ price tag? Wattage and cost. Depending on your usage scenario the 5350 is just as fast but consumes 40% of the power and costs somewhat less. Many home-server workloads tend to be very thready - eg you've got a thread for each Samba login, HTTP download, tar/unrar/unzip, etc. The A6-7400K wins in single threaded performance, but many of these workloads are also not really that processor-limited. tar -x or unzip aren't the bottleneck in TYOOL 2015. The exception is if you're running something like Plex and it can take advantage of GPU-accelerated transcoding. Someone else said that the 5350 is good enough for one HD (1080p?) transcode stream at a time, but the A6-7400K definitely has more GPU muscle and if that's your bottleneck it'll do better. Note that GPU transcoding is not as high-quality as CPU transcoding - it's fine for transcoding on the fly, but if you're archiving your MythTV rips you'll probably want to run that on CPU.

Maybe that's gotten better as the platform matured? Fairly sure AMD has refined the construction cores enough that a 9590 based off the latest iteration would "only" consume ~150w. Godavari and Carrizo both represent some impressive gains in power efficiency even if the improvements to single core performance have been less per iteration compared to Intel. But no one wants that right now, and with Zen so theoretically close, then . Maybe Bristol Ridge will be the last gasp of a high performance construction core for the end of 2015, early 2016 to get AM4 volume up?I have the biggest blue balls right now for TYOOL 2016, you don't even loving know AMD.

FaustianQ posted:So RIP AM1, you were a good platform The 5350 was based on their Jaguar microarchitecture, which was basically their low-power architecture, not a sizedown of a construction core. Depending on how many GPU cores they tossed on there it could be anywhere in the range from a server processor (5350) to a laptop chip/grandma-puter (A6-5200) all the way up to the console range (PS4 and Xbone). In answer to the question of "will we see more low-power chips dressed up as nettop mITX boards" the answer is "yes, undoubtedly". No more AM1 socket itself, though, which I actually am a bit butthurt about. What the gently caress was the point of not soldering them down if you never offer an upgrade past the original 4 processors? Right now actually I would say that the best buy is probably the Intel J1900 boards. In terms of CPU performance it's pretty damned close, and you can get them on a mobo for $60 now that the J2900s are coming out. This isn't really the thread for it, but I have the weirdest boner for using Thin-mITX boards as commodity blade servers. There's a company who makes chassis that fit 8x thin-ITX boards in 4U of space. That'd be fun with some Xeons, just wish they weren't $2100 a pop. gently caress yo' Raspberry Pi cluster
