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 18th best 3DMark 11 Performance Physics score among the 720 benchmarked CPUs in our database. It achieves 71.17% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 26,325 score and $429 launch price (MSRP) gives it a performance per dollar of 61.36. This is the 31st best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i9-13900K CPU

The Intel Core i9-13900K is a 24-core (32-thread) processor built for the desktop CPU market. It launched in Q3 2022 with a suggested retail price of $589. It is part of Intel's Core i9 lineup, which is based on the Raptor Lake microarchitecture. The i9-13900K is compatible with Intel Socket 1700 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 770 integrated graphics solution.

Memory and Cache

The Core i9-13900K supports DDR4-3200, DDR5-5600 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i9-13900K has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 36 MB.

Cores and Clock Speeds

The Core i9-13900K features 24 total cores which can process 32 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 24 cores consist of 8 P-Cores and 16 E-Cores. P-Cores are designed for high-performance tasks and E-Cores are intended for efficiency and lighter tasks. The base clock speed of the CPU is 3.0 GHz, and it can boost up to 5.8 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.
