The AMD Ryzen 7 7800X3D 8-core CPU with 5.0 GHz Precision Boost 2
The AMD Ryzen 7 7800X3D from the Raphael processor family features eight CPU cores based on the "Zen 4" architecture . Following "Zen 3," this is the fifth generation of the Zen microarchitecture. Compared to the previous generation, each processor core now has access to the entire L3 cache. This has significantly improved gaming performance. Furthermore, the Ryzen 7000 processors offer significantly increased per-clock performance and a higher boost clock.
When paired with an AMD X670(E) or B650(E) chipset, the AMD Ryzen 7 7800X3D supports the PCI Express 5.0 standard, which is twice as fast as PCIe 4.0. All Ryzen 7000 processors utilize the AM5 platform and were designed for use with compatible AMD chipsets. An update to the latest BIOS version is required.
The AMD Ryzen 7 7800X3D features eight physical CPU cores , each capable of processing two threads simultaneously thanks to Simultaneous Multithreading (SMT). With the addition of eight virtual cores, the number of processing cores effectively doubles to 16. This 8-core processor operates at a high base clock speed of 4.2 GHz per core, which, thanks to Precision Boost 2, adapts precisely to the specific application scenario in real time, boosting up to 5.0 GHz within its 120-watt Thermal Design Power (TDP) .
The silicon of the CPU cores is lithographed using the advanced 5nm FinFET manufacturing process with stacked transistors (also called 3D transistors) using Extreme Ultraviolet (EUV) technology. The space gained on the processor die due to the significantly reduced feature sizes allows for the integration of more cache memory .
The I/O chiplet in the CPU package, responsible for data lines, is manufactured using a 6-nanometer FinFET process and provides 24 PCIe lanes. Four lanes are reserved for the connection to the motherboard chipset and four for connecting NVMe SSDs. This leaves 16 lanes for communication with graphics cards, while additional PCIe lanes are provided for further storage devices, expansion cards, and peripherals, depending on the motherboard chipset.
PCI-Express 5.0 with AMD X670 or B650 chipset
When paired with an AMD X670/E or B650/E chipset, the AMD Ryzen 7 7800X3D supports the PCI Express 5.0 standard. PCIe 5.0 is backward compatible and can be used with all previous generation expansion cards. Each PCIe 5.0 lane offers twice the data transfer rate of PCIe 4.0, allowing an NVMe SSD connected via four PCIe 5.0 lanes to achieve a theoretical read/write speed of up to 15.75 GB/s.
The CPU's integrated memory controller supports fast and energy-efficient DDR5 memory in dual-channel mode with or without ECC error correction at a native clock frequency of 5,200 MHz, with significantly higher clock rates possible through overclocking.
AMD's 3D V-Cache technology boosts gaming performance
With 3D V-Cache, AMD is bringing a technology to market that significantly increases average performance in games. Thanks to 3D V-Cache technology, the AMD Ryzen 7 7800X3D is equipped with an impressive 96 MB of Level 3 cache .
Why does the new memory improve your gaming performance? When the cache is full due to heavy workloads, data is moved to RAM. However, access times to RAM are significantly higher than those to the cache memory located directly on the CPU. Thanks to the large 3D V-Cache, the processor can quickly access significantly more data and accelerate calculations. This means your system performs more actions in less time . Particularly demanding games benefit enormously – more frames per second result in a smoother gaming experience.
