About the AMD Ryzen 7 7800X3D CPU

The AMD Ryzen 7 7800X3D is a 8-core (16-thread) processor built for the desktop CPU market. It launched in Q1 2023 with a suggested retail price of $449. It is part of AMD's Ryzen 7 lineup, which is based on the Zen 4 microarchitecture. The 7800X3D 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.

Memory and Cache

The Ryzen 7 7800X3D supports DDR5 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Ryzen 7 7800X3D 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 96 MB.

Cores and Clock Speeds

The Ryzen 7 7800X3D 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 4.2 GHz, and it can boost up to 5.0 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 7800X3D 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 7 7800X3D has the 3rd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 89.07% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 32,947 score and $449 launch price (MSRP) gives it a performance per dollar of 73.38. This is the 19th best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Core i5-8400 CPU

The Intel Core i5-8400 is an end-of-life 6-core (6-thread) processor built for the desktop CPU market. It launched in Q4 2017 with a suggested retail price of $182. It is part of Intel's Core i5 lineup, which is based on the Coffee Lake microarchitecture. The i5-8400 is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the UHD Graphics 630 integrated graphics solution.

Memory and Cache

The Core i5-8400 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-8400 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 256 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 9 MB.

Cores and Clock Speeds

The Core i5-8400 features 6 total cores which can process 6 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.8 GHz, and it can boost up to 4.0 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.
