Intel Core i3-4005U

The Intel Core i3-4005U is a 2-core (4-thread) processor built for the mobile CPU market. It launched in Q3 2013. It is part of Intel's Core i3 lineup, which is based on the Haswell microarchitecture. The i3-4005U is compatible with Intel BGA 1168 motherboards and is fabricated on Intel's 22 nm manufacturing process. It features the Intel HD 4400 integrated graphics solution.

Memory and Cache

The Core i3-4005U supports DDR3 memory. In terms of cache, the Core i3-4005U 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 3 MB.

Cores and Clock Speeds

The Core i3-4005U features 2 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 1700.0 MHz. Higher clock speeds result in higher performance for the same microarchitecture. The multiplier is locked, making it incapable of overclocking for pushing performance further.

Integrated Graphics

The Core i3-4005U includes an integrated graphics solution called Intel HD 4400. 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

The Core i3-4005U has the 568th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 6.78% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
