About the Intel Core i5-9400F CPU
The Intel Core i5-9400F is an end-of-life 6-core (6-thread) processor built for the desktop CPU market. It launched in Q1 2019. It is part of Intel's Core i5 lineup, which is based on the Coffee Lake Refresh microarchitecture. The i5-9400F is compatible with Intel Socket 1151 motherboards and is fabricated on Intel's 14 nm manufacturing process.
Memory and Cache
The Core i5-9400F supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i5-9400F 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 i5-9400F 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 2.9 GHz, and it can boost up to 4.1 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 i5-9400F does not include an integrated graphics solution. A dedicated graphics card will be required if you require a monitor with your computer.
Benchmark Performance
The Core i5-9400F has the 219th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 30.24% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
About the Intel Core i7-7740X CPU
The Intel Core i7-7740X is a 4-core (8-thread) processor built for the desktop CPU market. It launched in Q2 2017. It is part of Intel's Core i7 lineup, which is based on the X-Series 7th Gen microarchitecture. The i7-7740X is compatible with Intel Socket 2066 motherboards and is fabricated on Intel's 14 nm manufacturing process.
Memory and Cache
The Core i7-7740X supports DDR4 memory and features a quad-channel memory controller, allowing it to utilize 4 memory modules simultaneously.
