About the AMD Ryzen 7 5800X3D CPU

The AMD Ryzen 7 5800X3D is a 8-core (16-thread) processor built for the desktop CPU market. It launched in Q2 2022 with a suggested retail price of $449. It is part of AMD's Ryzen 7 lineup, which is based on the Zen 3 microarchitecture. The 5800X3D is compatible with AMD Socket AM4 motherboards and is fabricated on TSMC's 7 nm manufacturing process.

Memory and Cache

The Ryzen 7 5800X3D supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 7 5800X3D has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 64 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 96 MB.

Cores and Clock Speeds

The Ryzen 7 5800X3D features 8 total cores which can process 16 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.4 GHz, and it can boost up to 4.5 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Ryzen 7 5800X3D does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.

Benchmark Performance & Value

The Ryzen 7 5800X3D has the 15th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 73.63% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 27,236 score and $449 launch price (MSRP) gives it a performance per dollar of 60.66. This is the 33rd best in value for the 3DMark 11 Perf. Physics benchmark.

About the AMD Ryzen 9 3900 CPU
