I have never really pushed my 2500k, guess I should try one of these days before I decide to "upgrade"

I've never bothered to stress my 2500K simply because I'm happy at 4.4Ghz at bone stock voltages. I've got a big-rear end Silver Arrow on top of it and I've never seen it break 55-60C at load.

My 4670K (at 4.2 gHz) will tickle 80C but only if I'm stretching it (benchmarking or video encoding). Games only hit 60ish. I have a Noctua D15 (something like that) with one fan. Would the optional second fan help temperatures noticeably if I start pushing it a lot?

That sounds awfully high for what is the most overkill air cooler you can buy.

I understand that intel CPUs with the added "T" are downclocked to stay within a certain TDP range of 35 Watts. So what is the difference between a model with a higher model-number that is downclocked to a CPU with a lower serial number to begin with? E.g. Let's compare an i3 4130 at 3400Mhz which consumes 54 Watts to a i3 4370T at 3300Mhz consuming 35 Watts (not exactly the same Mhz but close). Which one is faster and why is this so complicated?

MaxxBot posted:Unless that 2500k is sitting at 5GHz or something you would get more than 10%, the benchmarks I saw were showing around a 8-10% increase from Haswell. In games, at least, the difference isn't impressive. A 4.5GHz 2500K performs outright better than a stock 3570K or 4670K. Overclocked Sandy Bridge also doesn't consume as much power as an overclocked Ivy or Haswell, and that's without talking about heat transfer issues with the nice gap between the IHS and die. When the CPU isn't the bottleneck, the difference between even a 4.5GHz 4670K and a stock 2500K is not worth talking about. Further evidence to that end is provided by AnandTech. Basically, there are good reasons the "Sandy Bridge is still relevant" drum gets beaten in this thread. Because it's true. HalloKitty fucked around with this message at 09:59 on May 30, 2015 |

So what is the difference between a model with a higher model-number that is downclocked to a CPU with a lower serial number to begin with? http://ark.intel.com/compare/81207,77480 The only two parameters that are different which matter for performance are that the 4370T is clocked very slightly slower but has a substantially larger cache (4MB instead of 3MB). Despite being larger it's probably still not going to do a huge amount so you're probably looking at a wash. You're overcomplicating your mental picture of this by thinking of the 'T' spec chips as "downclocked". Or perhaps the right way to put it is that you're complicating it in the wrong direction. Silicon process variation causes chips to have probability distributions on many dimensions, and one of them is power (holding frequency constant). Intel can bin-sort on this and sell the ultra low power chips for more money. They might also run some wafers with different process parameters. Leakier transistors switch faster, but use more power. By changing the process recipe a little, it's possible to deliberately skew the distribution of outcomes towards either slow-but-cool or fast-but-hot.

HalloKitty posted:In games, at least, the difference isn't impressive. Yeah, I should have specified that I was referring more to performance in multi-threaded CPU intensive tasks rather than games. I don't think we'll ever see a CPU give a big boost in gaming again for various different reasons. Col.Kiwi posted:That person has a seriously above-average chip. Yours I think is more average. I "sadly" have a below average 2500k in that it will NOT go beyond 4.2 and be stable, no matter what. But a 4.2GHz 2500k is still pretty goddamn good to be quite honest. It's definitely above average but quite a few people were hitting those numbers, I had my 2600k at 5GHz on air but for some reason it runs hotter now than it used to so I can't crank the voltage up that high anymore. Still not bad having it at 4.5GHz on a $20 air cooler though. MaxxBot fucked around with this message at 19:12 on May 30, 2015 |

My SB-E (i7-3820) is still rarely a bottleneck at 3.8 GHz (up from 3.6 GHz stock). I have however considered following one of the guides to Nehalem-style overclock it to 4.625 GHz, though I'm not sure if my Corsair H60 is enough for that...

god I love this CPU. Now to try and get the goddamn heatsink right so it's not hitting 80C while doing this. E: it drops back to 30C within a second or two after it's done encoding. Would that happen if the HSF was seated right? Panty Saluter fucked around with this message at 16:31 on May 31, 2015 |

My 4790k will burst straight from about 33C up to about 65C in an instant if I encode in Handbrake, then drop almost straight back down to 33C within moments. So aside from the upper heat you are hitting (which may or may not be normal, depending upon your ambient temp in the room) that is pretty normal for an Intel as far as I can tell.

# ? May 31, 2015 21:08 |
|
Yeah I'm seeing now that 80C is pretty normal for a Haswell under normal duress (which x264 certainly qualifies for). I only see 60ish with video games so maybe I'm making a mountain out of a molehill.

Yea, its normal for temp to shoot up that fast.

Biostar is supposed to have at least 1. Its going to be a 'budget' mobo though. I haven't been too impressed with their budget stuff before. Yea it was cheap but the build quality was PCChips-esque and they didn't last long.

Huh that i5-5675C is listed cheaper than I thought it would be. Not bad for 275$ at all if you're building a small box with iGPU. If you're too lazy to read it murders AMD A10's stone dead, and pokes the heels of low end AMD R7 and Nvidia 750 cards. sauer kraut fucked around with this message at 12:28 on Jun 2, 2015 |

All those years AMD worked on APUs, and Intel just up and doubles their graphics performance in one release. Impressive, especially the power consumption figures.

Just to temper any expectations, the iGPU was 15 % slower than a GTX 750 (non-Ti) playing GTA V at 720p minimum settings. A cool boost nonetheless, but not quite displacing low-end dGPUs yet.

sauer kraut posted:I have no idea who that is but apparently they're worth 10 times more than AMD They make FPGAs, chips that can be programmed at the hardware level rather than running software. They're expensive but extremely useful for high-bandwidth/low-latency stuff - the G-Sync module uses an Altera FPGA to do the heavy lifting for example.

I found this surprising at first, but Intel is clearly trying to diversify its offerings. I'd think there would be a usage case for FPGA type devices in a super computing application in combination with the Phi and a standard Xeon.

The weak CPU performance increases once again mean nobody needs to upgrade, but that said... Holy poo poo snacks, those iGPU numbers are seriously impressive. Well, they out-AMD'd AMD in that market, and now it's looking reasonable to build an HTPC/entry level gaming machine with no GPU. That's one hell of a small, efficient box.
