Thanks for the informative OP. Does Bulldozer have anything comparable to Sandy Bridge's QuickSync hardware transcoding engine? For me, video transcoding is the only usage scenario where I wish I had a faster CPU. Even my dated 2.13 C2D in the MBA is sufficient for just about everything else I do. So looking at this picture:  … I really hope that Bulldozer has a similar trick up its sleeve to not end up near the "unaccelerated" time, or else I won’t even consider it.  //edit: To clarify, Quick Sync is faster and almost as good as x86 in quality, whereas GPU based solutions are much worse in quality and in some cases not even faster than x86. GPU encoding also doesn’t scale well, if at all. Here’s the detailed anandtech article. (and check what CUDA does to the police car scene at the bottom of the article). After googling for a bit, I don’t think AMD has any similar feature for Bulldozer. Meh.

You Am I posted:AMD will find someway of screwing it up, like dodgey third party chipsets or some CPU bug. Then it’ll probably be their last screwup, because I don’t see how they have a chance in the x86 game once Ivy Bridge is out. See Intel’s 22nm Tri-Gate Transistors and AMD’s lack of having something comparable within the near future.

Factory Factory posted:One of the rumors going around, not sure if it was for PS4 or XboxNumbers, was that there would be a CU set aside for GPGPU programming to take over some of the highly parallel functions in the current CPUs of the PS3 and Xbox360. I would expect that extra CU to be responsible for background tasks such as the permanent, time-shift-like h.264 encoding and various streaming / decompression tasks. Possibly also some of the image and signal processing for the new Move/Kinect device? quote:Lead system architect Mark Cerny also confirmed the upcoming system will have a local storage hard drive, along with an extra chip build into the system with the sole purpose of handling all the PlayStation 4 downloading. Interesting enough about this second chip is the fact you will now not only be able to download games in the background as you continue to play, but a new feature coming to consoles is being able to download and play what your downloading all at the exact same time. //edit: nevermind, you’re talking about a CU in the APU and not an extra chip. Disregard this post.

Since this seems to be a realistic scenario now: If this really happens, why the heck doesn't Apple just buy AMD? Surely a company like Apple has analysts and insiders that can gauge the performance of Zen by now. They'd free themselves from Intel and probably get a boatload of useful GPU/CPU patents for their ARM chips as well.

SwissArmyDruid posted:Will save you the trouble of digging the answer out from answer from many times over: AMD's present arrangement with Intel contains a clause that states that if either party should be acquired (obviously this makes it only pertinent to AMD, and not Chipzilla) AMD's x86 license is terminated, as is Intel x86-64 license. This makes acquisition untenable for anyone desiring to enter the x86 space. Oh I see, thanks. That changes everything as AMD minus the x86 license and designs is not even attractive to Apple, even though they're rumored to switch to ARM. (thinner! lighter!  )I think there's a decent good chance we'll see Zen in future Macbooks assuming the performance pans out, unless they really switch ARM before that.

pixaal posted:Are the two lower ends more expensive than the Intel equivalent? That top one is a deal though! Going to wait on benchmarks but the prices are reasonable enough that I could see it being worth $50 to stick it to Intel. Actually taking into account motherboard it might be cheaper platform even if the CPU is more have to wait on pricing there too. i7 7700s have 4 cores, 6800K has 6. Ryzen has 8. I'm really interested in reviews/benchmarks now. Kaby Lake will probably still rule at single thread, particularly when overclocked, but I'm at the point where I'll gladly trade a good chunk of single thread performance to double the core count.

It's getting increasingly hard not to get excited. $490 for the top 8C/16T model would be a complete game changer if they can manage Haswell level IPC. I am a bit worried that the aggressive pricing is a hint at lower performance but we'll have to wait for benchmarks to find out. Unlike with Bulldozer the time is ripe for a bump in mainstream core count, particularly since many games these days are optimised for the 8 cores in the current gen consoles. Looking at Vega/Polaris performance I'm fairly sure that this would also lock down AMD's APUs for the next console generation. Opteron based Mac Pros with more than 16C/32T would also be in the cards.

If those benchmarks are really at 3.4 Ghz Base without turbo then AMD turned the desktop CPU market upside down and it would be pretty hard to recommend Intel CPUs for gaming in 2017. That being said I don't think there's the slightest chance that these benchmarks were really without any turbo. The "n/a" is probably a result of the variable, completely cooling dependant turbo boost. I expect Kaby Lake with a realistic 5 Ghz OC to win out vs a OCed 1800 X in todays gaming loads but the 4 additional cores could cause Intel serious headache in the next 1-2 years. edit: wccftech

Per-core OC/Turbo seems interesting because the system could select the best performing core and utilise that for single threaded loads. Kind of like binning the single best core for OC/Turbo on the 8 core die, or the two best cores for 2-core boost, if that makes sense. (perhaps I'm outdated and CPUs already do this)

The AM4 upgrade path would be one of the main selling points of Ryzen to me. Intels sockets seem so fragmented that I can't even be bothered to figure out which one would be "right" for me. My current homeserver/NAS/VM host/game streaming machine has a 4C/4T Haswell Xeon and I wouldn't mind more cores/threads but won't swap the mainboard for a socket that will be obsolete once again next year. Hopefully they'll support ECC/IOMMU with consumer cpus + workstation grade boards.

NewFatMike posted:What's the estimated price on that? Like $400? For half the power envelope (give or take, IIRC Intel and AMD calculate differently) of the 6800K, my hype juices are flowing. leaked pricing is ~$260 for the R5 1600X and ~$230 for the R5 1500.

the only reason why I added the 7700k is because it's the best ST CPU and benchmarks are readily available. it looks like the 7700k gains an additional ~25% from ST -> MT cinebench with hyperthreading so the 30% indicated by those leaks seem about right. as anime schoolgirl said it looks like IPC will be exactly on par with Haswell and there's a good chance that Zen will scale better with more threads thanks to a solid SMT implementation. now excuse me while I contemplate buying some $AMD

The R7 1700X is basically identical (CB) or 5% faster (3DMark) compared to the 6900K at $389 vs $1050. I suspect that the overclocking headroom will be minimal because XFR is essentially automated overclocking but the value looks tremendous. I hope this is not a flash in the pan and AMD can keep this up without Keller on board.

1600X @ 4.0 Ghz vs a 7600K @ 5.0 Ghz is going to be a fairly close race overall.  >50% of all 7600Ks will do that stable according to silicon lottery and judging from the early reports I'd be surprised if a 1600X goes far beyond 4.0. Intel will still have the edge for  . AMD for content creation (3D and video rendering, code compilation, VMs, etc).

SourKraut posted:The bundles or the processors? Aren't these 95w parts? the processors. it's all speculation but what we've heard so far the CPUs are very aggressively binned and barely scrape by their rated boost clocks with the (relatively beefy) stock coolers. higher voltages don't seem to do much except make them run a lot hotter, so it makes sense that one would need water to get a 1800X over 4.0 on all cores. I'm also pretty sure that their XFR-auto-OC-feature ignores rated TDP and clocks to the temperature limit. that bundle would confirm that.
