Solder vs. Paste about the Main i9-9900K

Only in the near past we reviewed Intel’s most recent Core i9-9900K and Main i7-9700K processors. In summary, the 9900K was fast, although not quick ample to justify the worth Which seems to become the final consensus amongst reviewers. In addition to pricing, another key concern was the working temperature. Most reviewers are reporting pretty superior inventory temperatures employing superior-conclude coolers and this basically kills the overclocking opportunity.
In our critique we used quite a bit of time discussing the stunning thermal overall performance. We understood the 9900K was destined to be a severely energy hungry CPU and for that reason was destined to be a incredibly hot product, I just didn’t assume Intel’s initial soldered chip in an exceptionally while to run rather as scorching since it did.

7700K and 8700K chips

Up to now we’ve delided 7700K and 8700K chips with wonderful effects. Employing liquid metal dropped temps by a minimum of 20 degrees however a giant Component of that enhancement was achieved by removing the IHS glue which lessens the gap concerning the CPU die and heatspreader.
Continue to we understand that soldering CPUs will work a good deal much better than the paste strategy Intel’s been employing to save lots of on output costs For many years now. We know this because Intel’s desktop CPUs ran much cooler back again after they ended up soldered in 2011, the Sandy Bridge days for that mainstream desktop, even though the superior-stop desktop components have been soldered up right until the Broadwell-E period in 2016.Best Budget Laptop
For instance, a Core i7-3770K managing at four.7 GHz using one.35v would peak at just about ninety levels managing an AIDA64 tension check employing a significant tower fashion air cooler. Beneath Nearly the identical situations but with one.4v, a lot more voltage, the 2600K operates at least twenty levels cooler.
That becoming the case we ended up anticipating the 9900K for being anything Unique, and not the type of Unique it turned out to get. What we planned to know is how far better is definitely the solder method utilized by the 9900K when compared to the paste of the 8700K/8086K? To learn we’ve disabled two 9900K cores which correctly turns it into an 8700K or 8086K. Admittedly, it’s far from an exact science given that the 9900K is actually a physically more substantial chip packing extra L3 cache, nevertheless it’s about as near as we could get Along with the components we have out there.
The Core i5-9600K may make for a much better comparison but we’re however looking ahead to our chip to reach, so we will revisit that down the track. The 9600K is simply a 9900K with two dies disabled, however , you do get the scaled-down L3 cache. Anyway, this comparison must give us a pretty good notion of just the amount of of an advancement Intel’s STIM tends to make.

For the main check configuration

we locked the two the 9900K and 8086K at four.five GHz over the MSI Z390 Godlike. Blender was employed to position total load on all cores and once more both equally CPUs have been tested with 6-cores active and for this examination the voltage selections were left on automobile.
This saw the 9900K running at one.16v In most cases plus the 8086K at one.26v. The 9900K noticed a peak core temperature of 61C and also the XTU software package also documented a 61 C package temperature.
The 8086K On the flip side went as high as 74 C over the offer by using a peak core temperature of 72c. So to the 4.5 GHz auto voltage comparison the soldered process lessened temperatures by eleven degrees, a fifteen% reduction although as I observed voltages ended up also eight% reduce. The package TDP was also 16% better over the 8086K hitting one hundred twenty five watts opposed to just 107 watts to the 9900K.
That staying the situation for the subsequent test I locked the voltage at one.35v on the two CPUs, leaving the operating frequency at 4.5 GHz. This evened items up and now the 8th gen processor was hitting at deal TDP of a hundred forty five watts whilst the 9th gen chip hit 144 watts. That’s a sixteen% boost to the 8086K within the prior examination as well as a 35% raise for the 9900K.

The 9900K Alternatively

That’s a good outcome for your soldered 9900K, that said we’re previously Practically at 80 degrees, so simply how much hotter do items get at 5.one GHz While using the very same one.35v and Exactly what are the improvements over the six-core 8th gen part? When you remember I opted to run my 8700K examination rig at 5 GHz as the temperatures ended up way more suitable than what I was viewing at five.one GHz and exactly the same is accurate for your soldered 9900K.
In comparison the 9900K peaked at 91 degrees to the core and ninety C for that package deal. The typical voltage in the load exam was one.366v which resulted inside a package deal TDP of 181 watts. So this means when overclocking the soldered chip was just three degrees cooler than what we observed With all the 8th gen design applying paste. This also points out why we observed a ninety eight degree functioning temperature with all eight-core Lively, that’s actually a Significantly scaled-down enhance than we would have guessed.
