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 417th best 3DMark 11 Performance Physics score among the 720 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 i3-N305 CPU

The Intel Core i3-N305 is a 8-core (8-thread) processor built for the mobile CPU market. It launched in Q1 2023 with a suggested retail price of $309. It is part of Intel's Core i3 lineup, which is based on the Alder Lake-N microarchitecture. The i3-N305 is compatible with Intel BGA 1264 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 770 integrated graphics solution.

Memory and Cache

The Core i3-N305 supports DDR4-3200, DDR5 memory and features a single-channel memory controller, allowing it to utilize 1 memory modules simultaneously. In terms of cache, the Core i3-N305 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 96 KB in size, providing rapid access to crucial instructions. Its L2 cache, at 2 MB, 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 i3-N305 features 8 total cores which can process 8 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 100.0 MHz, and it can boost up to 3.8 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-N305 includes an integrated graphics solution called UHD Graphics 770. 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 i3-N305 has the 279th best 3DMark 11 Performance Physics score among the 720 benchmarked CPUs in our database. It achieves 24.13% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 8,926 score and $309 launch price (MSRP) gives it a performance per dollar of 28.89. This is the 123rd best in value for the 3DMark 11 Perf. Physics benchmark.
