About the Intel Atom Z3795 CPU

The Intel Atom Z3795 is a 4-core (4-thread) processor built for the mobile CPU market. The Z3795 is compatible with UTFCBGA1380 motherboards and is fabricated on a 22 nm manufacturing process. It features the Intel HD Graphics for Intel Atom Processor Z3700 Series integrated graphics solution.

Memory and Cache

In terms of cache, the Atom Z3795 has multiple levels of cache. Its L1 cache, which is the smallest and fastest, is 224 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 0 MB.

Cores and Clock Speeds

The Atom Z3795 features 4 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 1590.0 MHz, and it can boost up to 2390.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Atom Z3795 includes an integrated graphics solution called Intel HD Graphics for Intel Atom Processor Z3700 Series. 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 Atom Z3795 has the 684th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 3.52% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.

About the Intel Core i7-11800H CPU

The Intel Core i7-11800H is a 8-core (16-thread) processor built for the mobile CPU market. It launched in Q2 2021 with a suggested retail price of $395. It is part of Intel's Core i7 lineup, which is based on the Tiger Lake-H microarchitecture. The i7-11800H is compatible with Intel BGA 1787 motherboards and is fabricated on Intel's 10 nm manufacturing process. It features the UHD Graphics 750 integrated graphics solution.

Memory and Cache

The Core i7-11800H supports DDR4 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-11800H 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 1.25 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 i7-11800H features 8 total cores which can process 16 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The base clock speed of the CPU is 1900.0 MHz, and it can boost up to 4.6 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 i7-11800H includes an integrated graphics solution called UHD Graphics 750. 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 i7-11800H has the 108th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 45.24% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 16,736 score and $395 launch price (MSRP) gives it a performance per dollar of 42.37.
