Intel Core i9-10900, 10C/20T, 2.80-5.20GHz, boxed

Neben den K-Modellen mit offenen Multiplikator bietet Intel auch sehr ähnliche CPUs mit leicht reduziertem Funktionsumfang an. Wir haben uns die non-K-Version des Core i9-10900K genauer angesehen und haben eine Hand voll ältere Modelle zum Vergleich gebeten.

The Intel Core i9-10900 is our last 10th Comet Lake 10th Generation processor review. I've looked at pretty much the whole range, the only reason the i9-10900 is last is because it wasn't in stock anywhere until last week. I'm buying these CPUs, Intel isn't sampling anything other than the i9-10900K and i5-10600K. With Comet Lake, Intel was forced to make concessions because AMD's Zen 2 architecture is more power efficient due to the 7 nanometer production process, which offers more cores and threads. AMD CPUs are usually more affordable than Intel offerings, too. Comet Lake opens up HyperThreading to the whole lineup—previously, it was limited to the top models, which definitely helps with application performance. Cache sizes have also increased across the board. Comparing the Core i9-9900 to the i9-10900, we see that Intel has adjusted the core configuration from 8c/16t to 10c/20t, maximum boost is up from 5 GHz to 5.3 GHz, but base clock is down by 300 MHz (2.8 GHz vs. 3.1 GHz). The L3 cache is 4 MB bigger, but only because there are two more cores, and the amount of cache per core hasn't changed; TDP has remained 65 W, too.
