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 i7-13800H CPU

The Intel Core i7-13800H is a 14-core (20-thread) processor built for the mobile CPU market. It launched in Q1 2023 with a suggested retail price of $457. It is part of Intel's Core i7 lineup, which is based on the Raptor Lake-H microarchitecture. The i7-13800H is compatible with Intel BGA 1744 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the Iris Xe Graphics 96EU integrated graphics solution.

Memory and Cache

The Core i7-13800H supports DDR4-3200, DDR5-5200 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-13800H has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 80 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 24 MB.

Cores and Clock Speeds

The Core i7-13800H features 14 total cores which can process 20 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 14 cores consist of 6 P-Cores and 8 E-Cores. P-Cores are designed for high-performance tasks and E-Cores are intended for efficiency and lighter tasks. The base clock speed of the CPU is 2.5 GHz, and it can boost up to 5.2 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 i7-13800H includes an integrated graphics solution called Iris Xe Graphics 96EU. 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 i7-13800H has the 42nd best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 62.86% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 23,253 score and $457 launch price (MSRP) gives it a performance per dollar of 50.88. This is the 45th best in value for the 3DMark 11 Perf. Physics benchmark.
