About the AMD Ryzen 9 7900 CPU
The AMD Ryzen 9 7900 is a 12-core (24-thread) processor built for the desktop CPU market. It launched in Q1 2023 with a suggested retail price of $429. It is part of AMD's Ryzen 9 lineup, which is based on the Zen 4 microarchitecture. The 7900 is compatible with AMD Socket AM5 motherboards and is fabricated on TSMC's 5 nm manufacturing process. It features the Radeon Graphics integrated graphics solution and is bundled with a Wraith Prism cooler.
Memory and Cache
The Ryzen 9 7900 supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 9 7900 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 1 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 64 MB.
Cores and Clock Speeds
The Ryzen 9 7900 features 12 total cores which can process 24 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 3.7 GHz, and it can boost up to 5.4 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.
Integrated Graphics
The Ryzen 9 7900 includes an integrated graphics solution called Radeon Graphics. This graphics processor is directly integrated into the CPU and is not as powerful as a dedicated graphics card. While integrated graphics can handle basic tasks like web browsing and office applications, it is not suitable for more demanding activities such as gaming or video editing, where a dedicated graphics card offers superior performance.
Benchmark Performance & Value
The Ryzen 9 7900 has the 19th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database.
