This held true at both idle and when the CPU was under 100% load. I'm selling an Intel Core i7-4790K 4.0 GHz Quad-Core (BX80646I74790K) Processor with an ASRock Z97 Extreme 4 Motherboard and 16 Gigabytes of GSkill Trident X DDR3-2133 RAM. Even though the i7 4790K has a higher default core voltage and speed than its predecessor, the temperatures were still a bit lower when both CPUs were at stock speeds/voltages. haha. Both of those are unlocked processors too… yes even the Pentium! Below each graph is the raw data used to produce it.Wrapping things up here, Intel has done a good job tiding things over until Broadwell CPUs are released much later in the year.
I would be happy with what you have I cant get mine above 4.8GHz with 1.3V, that's delidded and on a custom water loop.You can be daily usage stable at 5Ghz. Probably not, unless the 10% average performance boost is worth it to you. In the case of the two CPUs tested today, the default core voltage for the i7 4770K was 1.08 V, while the i7 4790K came in at 1.15 V (as read in BIOS). I would probably shoot for max. Forums. 3. Intel says a new next-generation polymer TIM (NGPTIM) is now used that should give a greater amount of thermal headroom for overclocking.So, we have better thermal performance and a little higher power consumption. Once past 4.8 GHz, this CPU required a lot of voltage to go any further. i want this chip to last me around 4-5 years. I tested both CPUs at their stock settings while idle and at 100% load. The i7 4790K carries a higher TDP of 88 watts versus 84 watts for the i7 4770K, which to no one’s surprise will mean higher power consumption.
I've gone all the way up to 1.4v and it won't take.Probably just reached the limits of the chip. The below slides give you a summary of features on all three of the new CPUs.As expected, a quick glance at the Devil’s Canyon quad-core die map shows pretty much the same layout as the first generation of Haswell CPUs. A higher percentage is better on scored testing and a lower percentage is better on timed results. Below is a list of the components used for all three CPUs.Overclocking will be CPU dependent with Devil’s Canyon processors, just as it is with its predecessor.
4.9 at 1.29 is pretty good imo. There will be a Devil’s Canyon i5 4690K and a G3258 Pentium Anniversary Edition available for those on a tighter budget. level 2. i7-4790k@5GHz 1.41v delidded 16GB@2133MHz Original … In the case of the two CPUs tested today, the default core voltage … Each graph is based on percentages with the i7 4790K being the basis, and thus always being 100%. As previously mentioned, one of the improvements Intel implemented on the i7 4790K was a better thermal design. We still have a 1.4 billion transistor count, and the die size remains constant at 177mm². Depending on the test, we see anywhere from an 11% to almost 20% advantage for the i7 4790K. This was accomplished with a core voltage of 1.35 V, however slightly higher voltage was required in order to complete a few of the benchmarks at this speed. Most systems, even budget models, should run it fine. Stupid voltages that is.
However, after reading around other review sites, it seems they’ve all pretty much landed right where I did. Keep in mind that voltage is chip specific and will vary a bit from one CPU to the next. All models except the i7-4770K and i7-4790K additionally support vPro and TXT; Transistors: 1.4 billion; Die size: 177 mm²; Model number sSpec number Cores Frequency Turbo L2 cache L3 cache GPU model GPU frequency TDP Socket I/O bus Release date Part number(s) Release price Standard power: Core i7-4770: SR149 (C0) 4 3.4 GHz 3/4/5/5: 4 × 256 KiB: 8 MiB: HD Graphics 4600: 350–1200 MHz 84 W LGA … I then tested both CPUs when set to an identical 4.6 GHz overclock using 1.35 V. Here again, the i7 4790K showed better temperatures. The other major improvement is the thermal design, in particular, the Thermal Interface Material.
