About the Intel Core i7-12800HX CPU

The Intel Core i7-12800HX is a 16-core (24-thread) processor built for the mobile CPU market. It launched in Q2 2022 with a suggested retail price of $457. It is part of Intel's Core i7 lineup, which is based on the Alder Lake-HX microarchitecture. The i7-12800HX is compatible with Intel BGA 1964 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 i7-12800HX supports DDR4-3200, DDR5-4800 memory and features a dual-channel memory controller, allowing it to utilize 2 memory modules simultaneously. In terms of cache, the Core i7-12800HX 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 25 MB.

Cores and Clock Speeds

The Core i7-12800HX features 16 total cores which can process 24 threads simultaneously. The multi-threading capability allows the CPU to execute multiple computational tasks in parallel. The 16 cores consist of 8 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 2000.0 MHz, and it can boost up to 4.8 GHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture. The multiplier is unlocked, enabling overclocking for those seeking to push the CPU's performance further.

Integrated Graphics

The Core i7-12800HX 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 i7-12800HX has the 51st best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 60.48% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D. Its 22,373 score and $457 launch price (MSRP) gives it a performance per dollar of 48.96. This is the 51st best in value for the 3DMark 11 Perf. Physics benchmark.

About the Intel Atom Z3745 CPU

The Intel Atom Z3745 is a 4-core (4-thread) processor built for the mobile CPU market. The Z3745 is compatible with UTFCBGA1380 motherboards and is fabricated on a 22 nm manufacturing process.

Memory and Cache

In terms of cache, the Atom Z3745 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 Z3745 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 1330.0 MHz, and it can boost up to 1860.0 MHz under heavy workloads. Higher clock speeds result in better performance for the same microarchitecture.

Integrated Graphics

The Atom Z3745 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 Atom Z3745 has the 686th best 3DMark 11 Performance Physics score among the 721 benchmarked CPUs in our database. It achieves 3.41% of the performance of the best benchmarked CPU, the AMD Ryzen 9 7950X3D.
