Solder vs. Paste within the Main i9-9900K

Only recently we reviewed Intel’s most recent Core i9-9900K and Main i7-9700K processors. In summary, the 9900K was rapid, but not rapid ample to justify the worth and that seems being the general consensus among reviewers. In conjunction with pricing, another significant situation was the running temperature. Most reviewers are reporting really significant stock temperatures applying high-finish coolers and this fundamentally kills the overclocking opportunity.
Inside our assessment we spent quite a bit of time discussing the stunning thermal effectiveness. We realized the 9900K was going to be a seriously electricity hungry CPU and thus was destined to be a scorching product, I just didn’t count on Intel’s to start with soldered chip in an incredibly very long time to run pretty as incredibly hot because it did.

7700K and 8700K chips

Before we’ve delided 7700K and 8700K chips with astounding results. Working with liquid metal dropped temps by no less than twenty levels nevertheless a major Component of that advancement was achieved by eliminating the IHS glue which minimizes the gap amongst the CPU die and heatspreader.
Still we know that soldering CPUs functions quite a bit a lot better than the paste method Intel’s been utilizing to save on manufacturing expenditures For several years now. We know this for the reason that Intel’s desktop CPUs ran Considerably cooler back again if they have been soldered in 2011, the Sandy Bridge times for that mainstream desktop, while the significant-conclusion desktop parts have been soldered up until eventually the Broadwell-E era in 2016.
For instance, a Core i7-3770K working at 4.seven GHz working with 1.35v would peak at just over ninety degrees functioning an AIDA64 pressure exam utilizing a huge tower design and style air cooler. Beneath almost precisely the same circumstances but with one.4v, a lot more voltage, the 2600K operates at the very least twenty levels cooler.
That remaining the case we have been anticipating the 9900K to be a little something special, and not the sort of Exclusive it turned out to generally be. What we planned to know is how a lot better will be the solder method utilized by the 9900K compared to the paste in the 8700K/8086K? To find out we’ve disabled two 9900K cores which properly turns it into an 8700K or 8086K. Admittedly, it’s far from an actual science as the 9900K is usually a bodily more substantial chip packing additional L3 cache, nevertheless it’s about as near as we could possibly get While using the components We’ve got offered.
The Main i5-9600K could make for an even better comparison but we are however watching for our chip to arrive, so we are able to revisit that down the track. The 9600K is just a 9900K with two dies disabled, but you do receive the lesser L3 cache. Anyway, this comparison should really give us a very good notion of just the amount of the improvement Intel’s STIM will make.

For the main examination configuration

we locked both equally the 9900K and 8086K at four.5 GHz around the MSI Z390 Godlike. Blender was applied to position whole load on all cores and yet again both equally CPUs were being examined with six-cores active and for this test the voltage options were being still left on auto.
This saw the 9900K working at 1.16v In most cases as well as 8086K at one.26v. The 9900K noticed a peak Main temperature of 61C as well as the XTU software also reported a sixty one C offer temperature.
The 8086K However went as substantial as 74 C about the package with a peak Main temperature of 72c. So for the four.five GHz car voltage comparison the soldered approach lowered temperatures by eleven levels, a 15% reduction even though as I mentioned voltages have been also eight% reduce. The package deal TDP was also sixteen% larger over the 8086K hitting a hundred twenty five watts opposed to just 107 watts for that 9900K.
That being the case for the subsequent exam I locked the voltage at 1.35v on both CPUs, leaving the functioning frequency at four.five GHz. This evened things up and now the 8th gen processor was hitting at deal TDP of one hundred forty five watts although the 9th gen chip strike one hundred forty four watts. That’s a sixteen% increase with the 8086K in the previous take a look at in addition to a 35% boost with the 9900K.Best Buy Laptops

The 9900K Conversely

That’s an honest result to the soldered 9900K, Having said that we’re previously Just about at eighty degrees, so exactly how much hotter do factors get at five.one GHz While using the exact same 1.35v and What exactly are the enhancements about the six-Main 8th gen element? In the event you recall I opted to run my 8700K check rig at five GHz since the temperatures had been much more suitable than what I had been viewing at 5.1 GHz and a similar is genuine for that soldered 9900K.
Compared the 9900K peaked at 91 degrees with the Main and ninety C for the package. The typical voltage over the load take a look at was one.366v and this resulted within a bundle TDP of 181 watts. So This suggests when overclocking the soldered chip was just 3 levels cooler than what we saw Along with the 8th gen model applying paste. This also explains why we saw a 98 degree functioning temperature with all eight-Main Lively, that’s essentially a Significantly smaller sized boost than we would have guessed.
