AMD Ryzen 9 7900 vs AMD Ryzen 9 5900HX

AMD Ryzen 9 7900

► remove from comparison AMD R9 7900

The AMD Ryzen 9 79 00 is a high-end desktop processorfrom the Raphael series with 12 cores and hyperthreading (SMT), which means it can process up to 24 threads simultaneously. Launched in early 2023, the Ryzen 9 7900 is the fastest 12-core processor with 65 watts TDP.

The Ryzen 9 7900 clocks at 3.7 GHz base clock and reaches up to 5.4 GHz on one core in Turbo mode. This is also the difference to the higher clocked Ryzen 9 7900X.

At first glance, the internal structure of the processor has not changed fundamentally. The AMD Ryzen 9 7900 is still based on the chiplet design consisting of two CCD clusters, each containing a CCX with 8 cores. However, the manufacturing process has been scaled down to 5 nm, which ensures higher clock rates. There is also the IO die, which contains the memory controller and the iGPU, among other things. This is now manufactured in a 6 nm structure width.

The AMD Ryzen 9 7900 can impress in games thanks to the significantly improved IPC.

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.
