AMD Ryzen 9 5900HX vs AMD Ryzen 9 5900X

AMD Ryzen 9 5900HX

► remove from comparison AMD R9 5900HX

The AMD Ryzen 9 5900HX is a processor for big (gaming) laptops based on the Cezanne generation. The R9 5900H integrates all eight cores based on the Zen 3 microarchitecture. They are clocked at 3.3 (guaranteed base clock) to 4.6 GHz (Turbo) and support SMT for a total of 16 threads. The chip is manufactured on the modern 7 nm TSMC process. The "X" in the name indicates the overclocking capabilities of the CPU.

The new Zen 3 microarchitecture offers a significantly higher IPC (instructions per clock) compared to Zen 2. For desktop processors AMD claims 19 percent on average and in applications reviews showed around 12% gains at the same clock speed.

In addition to the eight CPU cores, the APU also integrates a Radeon RX Vega 8 integrated graphics adapter with 8 CUs and up to 2100 MHz. The dual channel memory controller supports DDR4-3200 and energy efficient LPDDR4-4266 RAM. Furthermore, 16 MB level 3 cache can be found on the chip.

Performance

The average 5900HX in our database trades blows with Intel's Core i9-11980HK, as far as multi-thread benchmark scores are concerned. While not much faster than the less power-hungry Ryzen 9 5900HS, this is still a great CPU for quality gaming laptops as well as DTRs and high-performance mini-PCs, as of mid 2022.

Thanks to its decent cooling solution and a long-term CPU power limit of 80 W, the Strix Scar 17 G733QSA-XS99 is among the fastest laptops powered by the 5900HX that we know of. It can be roughly 15% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

This Ryzen 9 series chip has a default TDP (also known as the long-term power limit) of 45 W, a value that laptop makers are allowed to change to anything between 35 W and 54 W with clock speeds and performance changing accordingly as a result. Either way, a high-performance cooling solution is a must for a CPU like this.

The R9 5900HX is built with the 7 nm TSMC manufacturing process resulting in decent, as of late 2022, energy efficiency.

AMD Ryzen 9 5900X

► remove from comparison AMD R9 5900X

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.
