Palladium posted:Besides like the 7700K, how much OC can you realistically get for a K-chip that is already at base 4.2GHz....maybe 10%? I'm skeptical that AMD will manage to get to i5-4690K single threaded speed, and it's OK if they're not quite there if they're selling $300 8 cores. The 5960X isn't quite at 4690K single threaded speed, even!

Palladium posted:Besides like the 7700K, how much OC can you realistically get for a K-chip that is already at base 4.2GHz....maybe 10%? AMD even slightly undercutting them, even with Sandy Bridge IPC and current-ish instruction sets, would light a fire under Intel's rear end - but Intel might just settle for getting burnt given the state they're in. dont be mean to me fucked around with this message at 19:38 on Jan 3, 2017 |

AMD wants to bring the fight to the E5/E7 Xeons, and probably just like the last time they were competitive they can sell quad socket SKUs at 2 socket prices.

If past 10 years of AMD launch prices is of any indication, they will bite the heels of Intel pricing even if they had the clearly inferior chip. If Zen is the Broadwell IPC savior like the fanboys craved, we can pretty much write off any meaningful price war with Intel. Palladium fucked around with this message at 20:07 on Jan 3, 2017 |

Being barely on top does not a king make. Then this shows up in the conclusion: quote:The fact that there’s a new performance champion gives us something to cheer about after the Skylake/Devil’s Canyon discussion is a plus for enthusiasts with a short upgrade cycle. Anandtech used to give a good cost-benefit bottom line in their conclusion, but this is all wet noodle. I mean, yes, technically, press buttan on Kaby for literally the absolute top.

Professor Science posted:eh? are you talking about the calling convention? because you definitely don't have to push/pop all registers on every function call (caller vs callee saved regs, liveness analysis) I thought that was pretty clear talking about caller/callee, was there something incorrect about "if you actually want to use them" conditional? I understand I work in a niche area but more registers are so often pitched as a panacea and I rarely see the tradeoffs actually examined. Renaming gets around most of the OoO bottlenecks, conventions mean memory hits are often incurred on usage indirectly. Like is there a particular workload that always benefits? Anything computationally heavy gets memory-bound anyway.

That is 600 MHz faster than the stock Turbo clock rate and a good 300-400 MHz faster than I have been able to reliably run at on my various Core i7-6700K parts over the last year.

If it was running at only 70 (under water, granted) then that should make for really good temps de-lidded. If it's similar to plain old Skylake under the hood, that is.

If Intel/Micron are showing this off, it's much closer to reality than previous concepts. Also, a few pages ago people were talking about Intel and their short lived idea of selling cards that would unlock better performance. I'm pretty certain it was exclusively for OEM Pentium models and the unlock was for more clock speed. Not any additional cores or HT functionality.

Though if the H100i GTX is capable of keeping this thing cool without a delid, drat I need to upgrade from my OG H100 for my 3930K. Things still good at encoding near 100% at just around 70C at times, but I'd like to loose 5C or so on that. Really do hope AMD can present something as everything at Intel seems to be really stagnant and lacking any sort of drive.

If anybody's looking for the bright side of this launch, it's that Pentiums picked up hyper-threading and have the full media capabilities. $60 chip with 4 threads and native 4K HEVC and VP9 decode? Don't mind if I do. This is going really far down the codec details rabbit hole, but I'm very curious to see how software encoded h264 looks vs hardware encoded HEVC.

The massive RAM speed increase combined with the CPU significantly raises the minimum FPS/reduces stuttery frame times, even if max FPS doesn't go up all that much (Since that part is still down to your GPU at the resolutions any of us play at). Especially so if you're still using DDR3 1333 or 1600 on the Sandy Bridge system- That review comparison is using maxxed out DDR3 2133.

So my ancient Core 2 Quad box from like 10 years ago died. It was my old desktop repurposed as a Plex server. My current desktop is an Ivy Bridge 3570K overclocked to like 4.2 GHz with 16 gigs of ram and a GeForce GTX 670. I'm debating on whether I should just build myself a new Kaby Lake desktop for my main rig and retire my Ivy Bridge rig to become my new Plex server. Does that sound like a not terrible idea?
