Get optimised performance with the AMD Ryzen 7000 High Efficiency Processors. The AMD Ryzen 9 7900 harnesses the power of twelve cores and twenty-four threads, with frequencies up to 5.4GHz. Utilising the innovative Zen 4 architecture and 5nm process, this CPU is future-proofed and supports a wide range of technologies, including DDR5 and PCIe 5.0. What’s more, thanks to a 65W TDP, this processor operates with incredible efficiency and remains at peak temperature with the included AMD Wraith Prism cooler.
The AMD Ryzen 9 7900 CPU is part of the AMD Ryzen 7000 Series. This model features a much lower TDP, with a maximum of 65W, making it a highly efficient CPU to instal in your gaming PC. At the top of the range, this CPU is equipped with twelve cores, twenty-four threads, and SMT (simultaneous multi-threading technology) to optimise your gaming, content creation, and workflow.
As with the rest of the AMD Ryzen 7000 Series, the AMD Ryzen 9 7900 has a speed over 5.0GHz, reaching frequencies up to 5.4GHz. What’s more, this CPU is equipped with an innovative cache, intelligently splitting 76MB across L1, L2, and L3 tiers. This increases the amount of accessible information, allowing for smoother gaming and optimised workflows. Overall, this generation has an incredible uplift in IPC (instructions per cycle) and performance.
With the new generation of processors comes a new architecture. Evolving the highly performative Zen 3, the AMD Ryzen 9 7900 CPU utilises the innovative Zen 4 architecture. The new front-end design is paired with machine learning, enabling a better focus on core performance. Large frequency fluctuations are avoided thanks to the 256-bit data width, which also speeds up language and image processing.
Constantly innovating, AMD has integrated fourth-generation FinFET technology creating the world’s first 5mn consumer CPU. Overall, the processor is smaller, faster, and has lower power transistors to optimise performance. Whilst the die is 18% smaller, new features have been integrated that not only enable great functionality, but improve the energy efficiency of the processor. At the same power output, there is up to 49% more performance than in previous architecture.
Included with the AMD Ryzen 9 7900 CPU is the AMD Wraith Prism Cooler. Designed with near silent acoustics, this lower profile CPU cooler is compatible with both the AM4 and AM5 socket, allowing for flawless performance with the Ryzen 7000 Series. With adjustable fan speeds and direct contact heat pipes, this cooler provides an efficient thermal solution that easily manages the 65W TDP. What’s more, this model sports vibrant RGB LEDs, compatible with a number of RGB software packages.
A key feature of the AMD Ryzen 9 7900 is how future-proofed the platform has been made. Starting with the new socket, AM5. AMD want this to be the platform that grows with you, supporting upcoming technological advances and industry standards.
For memory, AM5 supports DDR5 RAM modules, with maximum memory speeds up to 5200 MT/s. Additionally, a memory overclocking program has been developed specifically for the AMD Ryzen 7000 Series and DDR5, called AMD EXPO. This will offer optimised, on-click overclocking that can enhance 1080p gaming by 11% and reduce latency by up to 63ns.
The other future-proof feature is PCIe support. The AMD Ryzen 9 7900 is equipped with PCIe 5.0, for both graphics cards and storage. Enjoy ultra-fast connectivity on all your PCIe devices.

The AMD Ryzen 9 7900 CPU has integrated Radeon RDNA 2 graphics, built on an all-new I/O die in 6nm with advanced low-power Navi 2 architecture. This die operates with better efficiency than previous models, thanks to a low power draw when idle or under medium loads.
To operate an AMD Ryzen 7900 CPU, a motherboard equipped with an AM5 1718 LGA socket is essential. The compatible chipsets are:
To optimise compatibility, AMD Ryzen 7000 Series CPUs can be equipped with either an AM4 AIO or air CPU coolers or AM5 AIO or air CPU coolers. A Wraith Prism cooler is already included within the scope of delivery.
The AMD Rzyen 9 7900 CPU is great for high-performance gaming and content creation. The twelve cores and twenty-four threads are equipped with SMT technology to effortlessly handle complex processes. What’s more, the Zen 4 architecture is packed with features that will optimise your performance.
The AMD Ryzen 9 7900 CPU has 12 cores and 24 threads.
The AMD Ryzen 9 7900 CPU is compatible with the AMD AM5 socket. This AMD socket uses a land grid array (LGA) rather than a pin grad array (PGA), so there is no cross compatibility with AMD AM4 sockets. However, the outer socket shape has been designed so that your AM4 coolers will remain compatible.
The AMD Ryzen 7000 Series supports DDR5 RAM, this includes the AMD Ryzen 9 7900. The recommended memory speeds are between 5200MHz and 6000MHz.
