The Intel Core i7-12800H is a powerful mobile CPU designed for use in high-end laptops. It is based on the Alder Lake architecture, which was announced in early 2022, and features 6 performance cores (P-cores) and 8 efficient cores (E-cores). The P-cores are based on the Golden Cove architecture and support Hyper-Threading, which enables the CPU to support up to 20 threads when combined with the E-cores. The clock rate of the P-cores ranges from 2.4 to 4.8 GHz, while the E-cores have a clock rate of 1.8 to 3.7 GHz. The E-cores are similar in performance to the old Skylake cores, as seen in the Core i7-6920HQ. All cores can access up to 24 MB of L3 cache.
In terms of performance, the Core i7-12800H compares favorably to the AMD Ryzen 9 6900HS and the Intel Core i9-11900H in multi-threaded tasks. This makes it a great choice for use in gaming laptops and DTRs (desktop replacement laptops).
The integrated memory controller of the Core i7-12800H supports a range of memory types, including DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director, which is a hardware feature, helps the operating system to decide which threads to use on the performance or efficient cores for optimal performance. The CPU also integrates GNA 3.0 and DL Boost (via AVX2) for AI tasks. Quick Sync in version 8 is similar to that found in the Rocket Lake CPUs and supports hardware decoding of various video codecs, including MPEG-2, AVC, VC-1, JPEG, VP8, VP9, HEVC, and AV1. The CPU only supports PCIe 4.0, with a maximum of 8 lanes for a GPU and two lanes for SSDs.
The integrated graphics card of the Core i7-12800H is based on the Xe architecture and has 96 execution units (EUs) that operate at a maximum clock rate of 1.4 GHz. The CPU has a base power rating of 45 watts, with a peak power draw of 115 watts (PL2). However, most laptops will use a PL1 of around 60 watts. The SoC (system on a chip) is manufactured using a 10nm process at Intel.
In terms of features, the Core i7-12800H supports 64-bit instructions and includes Enhanced Intel SpeedStep technology, which allows the CPU to adjust its clock rate and voltage to conserve power. It also supports Intel Hyper-Threading technology, Intel Turbo Boost 2.0, and Intel Virtualization technology. The CPU has a maximum temperature of 100°C and is compatible with the FCBGA1744 socket.
The Core i7-12800H also includes support for Intel Advanced Vector Extensions 2 (AVX2), which are a set of instructions that can improve performance for tasks that involve floating point calculations. The CPU also supports Intel Optane Memory, which is a high-speed memory module that can be used to improve the overall performance of a system by providing a cache for frequently accessed data.
In terms of graphics, the Core i7-12800H includes the Intel Iris Xe Graphics G7, which has 96 EUs and a maximum clock rate of 1.4 GHz. This GPU is based on the Xe architecture and is capable of supporting a range of graphics and compute tasks. It supports DirectX 12, OpenCL, and OpenGL, and can handle up to three displays at once.
The Core i7-12800H is also equipped with a range of security features, including Intel Identity Protection Technology, Intel Secure Key, and Intel BIOS Guard. These features help to protect the system from various types of attacks and provide an additional layer of security for sensitive data.
In summary, the Intel Core i7-12800H is a high-end mobile CPU that is well-suited for use in laptops. Its strong performance, wide range of memory support, and hardware-level features make it a solid choice for a variety of applications, including gaming, AI tasks, and video decoding. Its integrated graphics and security features add to its overall value as a CPU for laptops.
