About the Intel Core i3-8121U CPU

The Intel Core i3-8121U is an end-of-life 2-core (4-thread) processor built for the mobile CPU market. It launched in Q2 2018. It is part of Intel's Core i3 lineup, which is based on the Kaby Lake-U Refresh microarchitecture. The i3-8121U is compatible with Intel BGA 1440 motherboards and is fabricated on Intel's 10 nm manufacturing process.

Memory and Cache

The Core i3-8121U supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i3-8121U 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 4 MB.

Cores and Clock Speeds

The Core i3-8121U 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 2.2 GHz, and it can boost up to 3.2 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 i3-8121U 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 i3-8121U has the 418th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 12.43% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i7-6600U CPU

The Intel Core i7-6600U is a 2-core (4-thread) processor built for the mobile CPU market. The i7-6600U is compatible with FCBGA1356 motherboards and is fabricated on a 14 nm manufacturing process.

Memory and Cache

In terms of cache, the Core i7-6600U has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 128 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 512 KB, is larger but slower than the L1. Its L3 cache, a shared resource among the CPU's cores, has a capacity of 4 MB.

Cores and Clock Speeds
