AMD Ryzen 9 3900X vs Intel Core i5-9400H
AMD Ryzen 9 3900X
► remove from comparison
Der AMD Ryzen 9 3900X ist ein Desktop-Prozessor der Matisse Serie mit 12-Kernen und Hyperthreading (SMT), weshalb dieser 24 Threads gleichzeitig verarbeiten kann. Mit dem Launch am 07.07.2019 ist der Ryzen 9 3900X der schnellste Ryzen 9 Prozessor und mit 105 Watt TDP spezifiziert. Bis zur endgültigen Verfügbarkeit des Ryzen 9 3950X bleibt der Ryzen 9 3900X allerdings das Topmodell, denn der Ryzen 9 3950X soll erst im September 2019 folgen und insgesamt 16 Kerne bieten.
Der Ryzen 9 3900X taktet mit 3,8 GHz Basistakt und kann per Turbo auf bis zu 4,6 GHz takten. Bei Last aller 12 Kerne erreicht der Ryzen 9 3900X maximal 4,3 GHz. Dank des Precision Boost 2 kann der Takt auf einem höheren Level gehalten werden, wie wir es schon von Zen+ her kennen.
Die Leistung des AMD Ryzen 9 3900X ist durchweg bei allen Anwendungen hervorragend. Vor allem bei Multi-Thread-Anwendungen kann hier der native 12-Kerner seine Stärken ausspielen und kann es sogar mit einem AMD Threadripper 1950X aufnehmen.
Die vier CCX-Cluster bestehend aus jeweils 4 CPU-Kernen, von denen jeweils drei aktiv sind befinden sich in zwei CCD-Packages (je 3 Kerne mit eigenem 16 MByte L3 Cache). Ein CCD-Package ist genau 74 mm² groß und wird im neuen 7 nm Verfahren bei TSMC gefertigt. Bei den beiden Ryzen-9-Prozessoren befinden sich zwei dieser CCD-Einheiten unter dem Heatspreader. Der I/O-Die ist separiert und kommt im mit der älteren 12 nm Strukturbreite daher, welcher weiterhin von Gobalfoundries gefertigt.
Bei Spielen kann der AMD Ryzen 9 3900X dank der verbesserten IPC überzeugen. Schlussendlich kommt es jedoch immer auf die Unterstützung der Spiele an. Wer nur Spielen möchte, ist gut beraten sich den AMD Ryzen 7 3700X genauer anzuschauen. Wer jedoch gleichzeitig Streamen oder Videos bearbeiten möchte, für diejenigen ist der Ryzen 9 3900X die bessere Wahl.
Intel Core i5-9400H
► remove from comparison
The Intel Core i5-9400H is a high-end processor for laptops with four cores based on the Coffee Lake architecture (2019 refresh, CFL-HR). The processor clocks at between 2.5 and 4.3 GHz (4.1 with 4 cores) and can execute up to eight threads simultaneously thanks to Hyper-Threading. According to Intel, the CPU is manufactured in an improved 14nm (14nm++) process. Compared to the predecessor, the Core i5-8400H from 2018, the 9300H is only clocked slightly higher (+100 MHz CPU Turbo, +50 MHz GPU).
The Coffee Lake architecture is similar to Kaby Lake and differs only in the amount of cores (now six cores for the high end versions) and the improved 14nm process (14nm++ according to Intel).
Performance
The Intel Core i5-9400H should perform similar as the older Core i7-7920HQ (3.1 - 4.1 GHz). The faster Coffee Lake CPUs, like the Core i7-9750H offers two additional cores and is therefore up to 50% faster in multithreaded benchmarks. Still, the performance of the i5-9400H should be sufficient for even demanding applications and games.
Graphics
The integrated Intel UHD Graphics 630 iGPU is supposed to offer a slightly higher performance as its clock rate has been increased by 50 MHz. The architecture is identical to that of the Intel HD Graphics 630. We do expect a performance improvement, but as a low-end solution it will probably only display current games smoothly at reduced details - if at all.
Power Consumption
Intel specifies the TDP with 45 watts and therefore the i5 is only suited for big laptops with good cooling solutions. Using cTDP-down, the CPU can also be configured to 35 Watt resulting in a reduced performance.
Beware, the CPU was not yet released at the time of writing and the information is based on leaks and early price list information (e.g. by Intel or on Baidu).
