Power, Temps, Overclocking

Next up we have power economic consumption and it's important to measure using software that stresses all cores. I've found Corona works well for providing accurate results, so these payload figures are based on the Corona benchmark later on a single pass and I'm reporting the maximum logged resultant role. This is total system draw and I'm exploitation a Cabac Power-Mate to measure from the fence in draw.

The Threadripper 1950X sucked down 257 watts and that meant total system consumption was 8% take down than that of the Core i9-7900X. Interestingly the 7980XE actually John Drew less power than the 7960X in this test. Both CPUs delivered similar performance so this suggests the 7960X had to time more aggressively to achieve that result and this meant greater great power draw.

Low-level overfull load the 7960X system was consuming about 25% more power than the 1950X while the 7980XE used up 16% Sir Thomas More power.

Due to the circumscribed time we had to test these new CPUs I haven't explored the temperature reduction options all that much. I simply threw them both on our custom liquid state cooled X299 test bed and got benchmarking. So I'm even to interpret how badly they punish air-coolers and AIO liquid coolers.

At stock clock speeds the 7980XE solely pushed temps as high arsenic 65 degrees which is certainly getting up there given that we birth a massive 360mm radiator attached to the loop.

Let's see how things look after a microscopic overclocking...

Time to tinker. The 7980XE overclocked whol cores to 4.1 GHz quite easily and it might be possible to go further just for now this is where I stopped due to might draw and a couple of other reasons. The 7960X was riant at 4.3GHz and of course we antecedently got the 7900X to 4.7GHz. Threadripper has also been down in A wellspring, clocked at 4GHz.

Clocked at 4.1GHz the 7980XE produced a multi-threaded grudge of 3974pts so bear to see people breaking the 4000 barrier with this one. That's a 20% increment over the out of the box performance. The 7960X saw a 17% boost as it rack up an splendid 3681 pts.

The Threadripper 1950X only managed to boost its out of the box public presentation aside 13% but notwithstanding that allowed for a hit of 3425 pts. Overclocked, the 7980XE was 16% faster than the 1950X. So what difference does this make in our extreme Blender workload?

Well not a huge add up. Both Skylake-X parts are today 9% faster while Threadripper was 11% quicker. Still the 16-CORE and 18-marrow Intel CPUs are blistering fast in this test.

What about power draw you ask? Overclocked, Threadripper pushes total system draw to 414 watts and that's bad extreme. However, it also pales in comparison to the 7900X at 475 watts, the 7960X pushing total arrangement draw just all over 500 watts and at length the 7980XE at 530 watts. Remember this is just Central processing unit load so if you have a few high-stop GPUs in your workstation you might to require a ZPM to power it.
