AMD 7800X3D Ryzen 7 CPU 8-core 3D V-Cache Unlocked AM5 Processor

The AMD 7800x3D CPU is aimed at the enthusiast desktop market and is part of the AMD Ryzen 7 family. Built on AMD's "Zen 4" architecture, it was formerly known as "Raphael AM5." It features 8 CPU cores and 16 threads, courtesy of Simultaneous Multithreading (SMT). The processor has a maximum boost clock of up to 5.0 GHz and a base clock of 4.2 GHz. In terms of cache, it includes 512KB of L1 cache, 8MB of L2 cache, and 96MB of L3 cache.

The CPU uses TSMC 5nm FinFET technology for its cores and TSMC 6nm FinFET for the I/O die. The CPU Compute Die (CCD) size is 71mm2, and the I/O Die (IOD) size is 122mm2. It has a default TDP of 120W and the package consists of two dies.

Overclocking features include support for AMD's EXPO Memory Overclocking Technology, Precision Boost Overdrive (PBO), and Curve Optimizer Voltage Offsets. It also supports AMD Ryzen Master software for further customization. The processor fits into the AM5 socket and is compatible with the X670E, X670, B650E, and B650 chipsets.

The CPU supports a range of instruction sets and extensions, including x86-64, AES, AMD-V, AVX, AVX2, and various SSE versions. It has a maximum operating temperature of 89°C, and it is recommended to use a liquid cooler for optimal performance.

Operating system support is extensive, including 64-bit editions of Windows 11, Windows 10, RHEL, and Ubuntu, although support can vary by manufacturer. In terms of connectivity, the CPU offers USB Type-C support and has four native USB 3.2 Gen 2 (10Gbps) ports. It also supports PCIe 5.0, with a total of 28 lanes, 24 of which are usable. It includes NVMe support for booting and RAID configurations.

Memory support includes DDR5 with dual channels, and it can handle up to 128GB. ECC support is also available, depending on the motherboard. Additionally, it features integrated AMD Radeon Graphics with two cores, clocked at 2200 MHz, and supports USB Type-C DisplayPort Alternate Mode.

What Are the Reviews Saying?

PCGamer's Review of the AMD Ryzen 7 7800X3D CPU praises its gaming performance efficiency. It delivers gaming performance at double the efficiency of the last-gen 3D V-Cache chip and practically double the efficiency of the Core i9 13900K. Its power-sipping nature also makes it impressively cool, with measurements topping out at 80°C under full multi-threaded load and roughly half of that during gaming. This makes it a solid choice for a cool and quiet gaming PC capable of the fastest gaming frame rates.

PCGamer also wrote that the AMD Ryzen 7 7800X3D also stands out for its ability to deliver gaming frame rates comparable to the most expensive processors in the business, the Ryzen 9 7950X3D and the Intel Core i9 13900K, despite having lower clock speeds. This is especially impressive considering its price point, making it a strong choice for gamers focused on performance.

The review from Tom's Hardware about the AMD Ryzen 7 7800X3D found that it is not as versatile as other chips and may not be suitable for users seeking an all-rounder processor. It falls behind in productivity applications due to power and thermal constraints. This makes it less suitable for tasks such as rendering or encoding. However, the Ryzen 7 7800X3D is exactly what AMD claims it to be — a highly specialized chip for gaming that won't offer as much performance in standard workloads as the regular Ryzen 7000 processors.
