Gravitas, how many K-corners were you running and what hardware setup? I'm personally curious because I work for an integrator and I want to see hard numbers against, say, K80s, given a modicum of optimization. For reference, I have CUDA benchmark numbers for 4 K80s with dual e5-26xx's on our hardware configuration. I know the whole point of K-landing is you shouldn't need to optimize, I just want to know where the sweet spot is for that optimization, especially versus CUDA.

For reference, I have CUDA benchmark numbers for 4 K80s with dual e5-26xx's on our hardware configuration. I was running just one Phi, quite briefly, hosted in a basic Haswell 4-core 4-thread Xeon, single CPU computer. It was a fun project, not very serious. When I turned out to be garbage for my load, I gave up on it. I think I posted dhrystone results in here already. I never got the Intel compiler sorted out, so I never got to run the vector units and the machine is pointless without them. Not that my workload was a very SIMD one either. I don't have the setup ready to run right now, I was basically homebrewing the ducting to cool the monster and I disassembled it a long while back. Fun ride, but a bad match. From what I have seen your code either works great on a GPU or you need a CPU. Stuff like branches? CPU. The Phi tries to kinda be in the middle of the CPU/GPU choice and if it only weren't garbage... Somehow all workloads I run are branchy as all hell and with unpredictable stride lengths and loop iteration counts. No GPU for me, but I can at least cluster across many computers.

If things already feel like they're happening as fast as possible, why change? Totally agree. I have been running an i5-2500k over clocked to 4.2 GHz in my rig since mid 2011, and just last week I had a visiting family member remark about how instantaneous everything felt while they were using it (I imagine the ssd containing the OS is part of that, to be fair). There is very little reason for me to upgrade, even for videogaming purposes. I can't see myself bothering until there is a need for more than 4 cores to avoid bottlenecking whatever flavour of gpu I have in the future.

Hell my C2Q 9550 Oced to 3.84 (2.84 stock) ran about the same with an SSD. Everything was instantaneous as far as basic usage was concerned. The only downside was the hacky way to get SLI to work on a X48 chipset, and the fact that even OC'ed, it wasn't powerful enough to really feed GPU's faster than a 580 or so at the time. Gave it to my Sis to do Photoshop stuff and it works like a charm for that to this day. Need to replace the SSD in it as its an old one without the Trim FW installed to it yet lol, but to upgrade it, you have to wipe the drive. Might just put in the old Plextor M3P's I just took out of my system as I needed more space then the Raid-0 240G they provided for these past years.

*snerk* You can run x86/AVX binaries on it natively, but even on KNL they will likely run like garbage unless you spend some time on them. In terms of total work, KN* and CUDA will both require you to expose a lot more parallelism in your code, it's just the language you do it in that differs. In terms of performance, K80 is significantly better than KNC.

I've got an I5-2500 non-k that's coming up on 5 years old now. Since OC'ing isn't an option, I take it an upgrade to Skylake is probably a good idea when I build my VR rig in a month or so? Should I go for an OC-able chip this time?

It is usually worth it if you buy a good motherboard and CPU cooler, OC'ing allows you to pull a good bit of extra performance out of your chip. If you would have had a K version of your chip, you would potentially have still been good for another year or two with a solid OC. And with the quality of some of the self contained water coolers out there now that are like 2 piece air coolers really, it is rather easy to keep things reasonably cool too.

The biggest boost here is that two USB 3 ports are required for Occulus VR (and probably others), and getting anew motherboard that includes a bunch will fulfill that nicely. If you can hold off making decisions around GPU's until at least April 7th, we will have some more news about next gen nVidia GPU's, and probably AMD as well, whcih should help with any planning you are making.

I'd kill for anything to run Lightroom faster than my i5-4690k @4.4GHz, but nothing helps no matter how much CPU, RAM, and I/O I throw at it. It's pure single-thread CPU. Can't help you on editing, but if you launch multiple export jobs they will run in parallel. So export your photos in 4 batches of N/4 photos each.

Latest, and no, the previewing of touching effects is GPU accelerated, such as brushes. Those layer on top of the photo. However, anything to do with white balance, color, or exposure (highlights/shadows/etc) is all reliant on the CPU, as is flipping between photos in a library. It doesn't help that Adobe's Fuji RAW converter is slow as hell in all this. (bla bla Adobe Fuji RAW bla bla demosaicing bla bla Capture One  I use LR and I like its workflow, I just want it to be as fast as working with JPEGs)

Well, I'm gettin' a Rift, so the extra USB3.0 slots will come in handy, besides I'd like to actually be able to use the front-panel ports on my case. I'm pretty much building a new system from scratch anyhow, as I don't have a SSD and the 560Ti I bought at the same time as the CPU isn't exactly going to cut the mustard for VR stuff. I'll probably spring for the OC-able CPU this time, as being able to ride out the rest of the decade+ without needing an upgrade would be nice. Any aftermarket coolers that are particularly good? I've never OC'd a thing in my life, despite having built a half dozen PCs over the years. And I can wait a week no problem, so hopefully the new GPUs are the step forward they've been advertised to be, or at least they'll cause a drop in 970/980Ti prices.

If anyone was considering a 980Ti, this is the deal to get. $545 for the MSI Golden, which has the all copper heatsink and is probably binned for massive overclocked. Also it's eBay, so chances are you wont pay taxes. Coupon code: C15LIMITEDTIME http://m.ebay.com/deals?&_trksid=p1468660.m2212&deal=5002796903

The only reason I upgraded from a Q9550 to a 2500K was because I was having weird mystery problems. (Unrelated to the actual CPU, it turns out).

Been trying to break into the VR market myself for ages since the KS, but timing and job position just doesn't seem to align for me.  That and now I seem to only be able to apply through the Facebook Careers page now which I haven't had much luck with.

What kind of idle power consumption would I be looking at for a W3565? I'd like to replace my mITX AM1 system with something that would be a heavier-duty server for ZFS and stuff. It's probably not going to run flat-out all the time, but I don't want to waste power idling if I don't need to. I have an old HP Z400 workstation with a W3565 and 16GB of ECC RAM right now - I could either build it on that, or sell/part it out and get something newer if there's a compelling tradeup there. Half wondering about looking for an AM1 mobo that supports ECC memory, but the W3565 is much faster and I probably won't notice an extra $10 in idle power per year or whatever.

You're also giving up quite a bit in clock speed, going to the quad core. Mr Chips fucked around with this message at 01:41 on Apr 4, 2016 |
