About the Intel Core i5-6400 CPU
The Intel Core i5-6400 is an end-of-life 4-core (4-thread) processor built for the desktop CPU market. It launched in Q3 2015 with a suggested retail price of $182. It is part of Intel's Core i5 lineup, which is based on the Skylake microarchitecture. The i5-6400 is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process. It features the HD Graphics 530 integrated graphics solution.
Memory and Cache
The Core i5-6400 supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-6400 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 6 MB.
Cores and Clock Speeds
The Core i5-6400 features 4 total cores which can process 4 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 2.7 GHz, and it can boost up to 3.3 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 Core i5-6400 includes an integrated graphics solution called HD Graphics 530. 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 Core i5-6400 has the 374th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 16.99% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 6,283 score and $182 launch price (MSRP) gives it a performance per dollar of 34.52. This is the 102nd best in value for the 3DMark 11 Perf. Physics benchmark.
