The AMD Ryzen 9 5900X is a high-end 12-core, hyperthreaded (SMT) Vermeer series desktop processor that can process 24 threads simultaneously. Introduced on October 8, 2020, the Ryzen 9 5900X is the fastest 12-core processor and is specified at 105 watts TDP. The top model, the AMD Ryzen 9 5950X, offers even more power and at the same time offers another 4 cores and 8 threads.
The Ryzen 9 5900X clocks with 3.7 GHz base clock and reaches up to 4.8 GHz on one core in turbo mode. However, when all 12 cores are loaded, up to 4.5 GHz is still possible.
The performance of the AMD Ryzen 9 5900X is consistently excellent in all applications and significantly better than the AMD Ryzen 9 3900X. AMD has been able to significantly improve its single thread performance in particular and even beats the Intel Core i9-10900K in this discipline. The multi-thread performance could also be improved. In an in-house duel, the AMD Ryzen 9 5900X can even take on an AMD Threadripper 2950X.
The internal structure of the processor has not changed fundamentally at first glance. The CCX structure has changed a bit compared to Zen2, because now a CCX consists of up to 8 CPU cores. So each individual core can access the complete L3 cache (32 MByte). Furthermore the CCX modules are connected to each other via the same I/O die, which we already know from Zen2. According to AMD, the Infinity-Fabric should now reach clock rates of up to 2 GHz, which in turn allows a RAM clock of 4.000 MHz without performance loss.
For the manufacturing processes, AMD also relies on TSCM for the Vermeer processors for the 7nm production of the CPU cores, although the I/O die is still supplied in 12nm by Globalfoundries.
In games, the AMD Ryzen 9 5900X is convincing thanks to the significantly improved IPC. With the AMD Ryzen 9 5900X, streaming can be done simultaneously with gaming. But if you only want to play games, you are well advised to take a closer look at the AMD Ryzen 7 5800X or the AMD Ryzen 5 5600X.
The Intel Core i7-14650HX is a high-end CPU based on the new Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 and is similar to the older Core i7-13700HX except for slightly higher CPU clock rates (max 200 MHz).
The total of 24 threads are divided into P-cores and E-cores, which we already know from Alder-Lake. The 13700HX offers 8 performance cores (P-cores) with hyperthreading and 8 efficiency cores (E-cores) without hyperthreading. A total of 20 threads are therefore supported. The P-cores clock from 2.2 to 5.2 GHz (single core) or 4.5 GHz (all cores) and the E-cores from 1.6 to 3.7 GHz. The integrated memory controller supports a maximum of DDR5 with 4800 MHz (and not 5600 MHz like the i9 HX models).
Compared to Alder Lake, the new Raptor Lake architecture offers improved P-cores (Raptor Cove architecture with more cache), more E-cores (same Gracemont architecture) and higher clock rates thanks to the improved Intel 7 process. Furthermore, Intel now supports faster DDR5 main memory in the top models (up to 5600 MHz in the i9).
The performance should be slightly above the older Core i7-13700HX (with the same TDP settings and cooling). This makes the CPU ideal for demanding tasks and games.
The 14650HX continues to be manufactured using Intel's improved 10nm FinFET process (Intel 7 process) and is specified with 55 watts of base power and 157 watts of turbo power.
