Level up your gaming, with the AMD Ryzen 9 7900X3D. This processor is optimised for mid-range gaming. With Zen 4 architecture and 3D V-Cache, the Ryzen 9 7900X3D is unlike any desktop processor in terms of performance. Utilising an innovative 5nm process, the die size has been reduced by 18% whilst IPC uplifts by roughly 13%. This model is the mid-range edition, with 8 cores, 16 threads, and SMT technology. Built for AM5 sockets, this processor supports DDR5, PCIe 5.0, and is future-proofed for upcoming advancements. Expect great things from this CPU.
As a mid-range CPU from the new AMD Ryzen 7000 Series, the AMD Ryzen 9 7900X3D delivers on gaming performance. Boasting twelve cores and twenty-four threads, this processor utilises SMT (simultaneous multithreading technology) to optimise performance during gaming workloads. Base frequencies for this processor are 4.7GHz but, as the AMD Ryzen 9 7900X3D is unlocked for overclocking, this can be boosted up to 5.6GHz with the use of Precision Boost 2 or Precision Boost Overdrive.
Overall, this generation of Ryzen processors has an incredible uplift in performance and IPC (instructions per cycle). Game with smooth frame rates, stream in high definition, and create content flawlessly. The maximum 120W TDP delivers premium performance, enabling you to get the most out of this processor.
3D V-Cache is an innovative cache system that allows the AMD Ryzen 7000X3D models to deliver incredible efficiency. The CPU’s cache memory is 3D stacked, which facilitates higher capacities and more simultaneous access to the data stored. The AMD Ryzen 9 7900X3D has a total 140MB cache, which is intelligently split into L1, L2, and L3 tiers.
With this generation of processors comes a new architecture. Evolving the highly performative Zen 3, the AMD Ryzen 9 7900X3D 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 seen in the previous architecture.
A key feature of the AMD Ryzen 9 7900X3D is how future-proofed the platform has been made. Starting with the new socket, AM5. AMD wants this to be the platform that grows with you, supporting upcoming technological advances and industry standards.
For memory, AM5 compatible with DDR5 RAM modules, ideally supporting speeds between 5200 and 6000MHz. 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 7900X3D 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 7900X3D 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 9 7900X3D 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. No cooler is included within the scope of delivery.
The AMD Rzyen 9 7900X3D CPU is great for gaming and creative workflows. 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.
AMD 3D V-Cache is an innovative 3D stacked cache system, that allows for greater capacities and simultaneous access to information.
The AMD Ryzen 9 7900X3D CPU has 12 cores and 24 threads.
The AMD Ryzen 9 7900X3D 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 7900X3D. The recommended memory speeds are between 5200MHz and 6000MHz.

This processor performs extremely well, upgrading from a 4790K how couldn't it. It runs cool under a 360mm Arctic Liquid Freezer II and obliterates games. However, there are a few things to consider before buying: Problem 1 - The Cost: Building an AM5 system is extremely expensive at the moment beyond the CPU with a decent motherboard and a good DDR5 RAM kit coming in at over £500 combined just to get you started. Going for an Intel alternative or an AM4 chip like the 5800X3D would be significantly cheaper overall. Problem 2 - The Design: Due to the design of the chip only having the 3D v-cache on one of the two CCDs, core parking during gaming workloads is applied, meaning 6 cores and 6 threads are deactivated so you're only utilising the 6 cores and 6 threads that hold the 3D v-cache while gaming. When the 7800X3D launches that CPU only have 1 CCD which holds all the 3D v-cache meaning all 8 cores will be available during gaming. Problem 3 - The Competition: Wait for the 7800X3D (£TBC) if you just want to game. If you want improved productivity go for the 7950X (£570) or 13900K (£580). If you want to do both and don't want to go Intel, spend the extra on the 7950X3D (£750). Overall, no one will be disappointed with this chip's performance, however pretty much everything else is a better option, I am overall happy with the chip however I do have some buyers remorse as the alternatives either, perform better or cost less and potentially in the case of the 7800X3D - both!
Having not used AMD for many years I was pleasantly surprised that paired with the Asrock x670e RS and Kingston Fury 6000 system booted immediately, overclocking well so far and has given my 7900xtx a massive boost over my older 8700K which was starting to bottleneck it. Temps around 40-50 idle and 70 when gaming with a Corsair H150i which is not the best AIO out there. Idle temps seem high but this is an average, some windows processes seem to bump it up temporarily so I am assuming it is a little sensitive at times.
