AMD Ryzen 7 5700X
► remove from comparison
The AMD Ryzen 7 5700X is a desktop processor with 8 cores and simultaneous multithreading (SMT), which means it can process 16 threads simultaneously. In April 2022, AMD presented the Ryzen 7 5700X, a new 8-core processor that is very similar to the AMD Ryzen 7 5800X. However, due to the lower TDP, there are no restrictions on the clock frequency. Nevertheless, the AMD Ryzen 7 5700X reaches up to 4.6 GHz in boost, which is only 100 MHz less than the AMD Ryzen 7 5800X. However, the base clock drops significantly to 3.4 GHz.
The performance of the AMD Ryzen 7 5700X is consistently excellent in all applications. The native 8-core can really show off its strengths, especially in multi-threaded applications, although the single-core performance has also been significantly improved compared to the older Zen 2 architecture.
The internal structure of the processor is similar to the AMD Ryzen 7 5800X. The CCX modules are also connected to each other via the I/O die, which we already know from Zen2. However, according to AMD, the Infinity Fabric should now achieve clock rates of up to 2 GHz, which in turn enables a RAM clock rate of 4,000 MHz without any loss of performance.
In terms of manufacturing processes, AMD also relies on TSCM for the 7nm production of the CPU cores in the Vermeer processors, although the I/O die is still supplied in 12 nm by Globalfoundries.
The AMD Ryzen 7 5700X is impressive in gaming thanks to the significantly improved IPC compared to Zen2. In terms of power consumption, the AMD Ryzen 7 5700X impresses with its low TDP of just 65 watts. This means that the processor can also be operated with a compact air cooler without any problems. The AMD Ryzen 7 5800X is operated with a TDP of 105 watts.
AMD Ryzen 9 3900X

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.
AMD Ryzen 9 3900

The Ryzen 9 3900 is a fast desktop CPU with 12 cores and 24 threads based on the Matisse series. It is the fastest 65 Watt CPU at launch in late 2019 and clocks the cores between 3.1 (base) to 4.3 (boost) clock (including Precision Boost). It uses 4 CCX-clusters where 3 of the 4 cores are activated. The CPU is manufactured in the modern 7nm process at TSMC. The I/O die on the package is separate and manufactured in 12 nm at Globalfoundries.
Due to the reduced Turbo speed, the Ryzen 9 3900 is aimed at content creators and other professionals that can make use of the 12 cores. For games, a fast 8-core CPU with higher boost clocks is the better choice.
