Intel Core i7-12800H vs Intel Core i5-11400T vs Intel Core i5-11600K
Intel Core i7-12800H
► remove from comparison
The Intel Core i7-12800H is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in early 2022 and offers 6 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 20 supported threads when combined with the E-cores. The clock rate ranges from 2.4 to 4.8 GHz on the performance cluster and 1.8 to3.7 GHz on the efficient cluster. The performance of the E-cores should be similar to old Skylake cores (compare to the Core i7-6920HQ). All cores can use up to 24 MB L3 cache. Compared to the 12900H, the 12800H is lower clocked and also features the full "Enterprise" set of vPro features (for remote management).
Features
The integrated memory controller supports various memory types up to DDR5-4800, DDR4-3200, LPDDR5-5200, and LPDDR4x-4267. The Thread Director (in hardware) can support the operating system to decide which thread to use on the performance or efficient cores for the best performance. For AI tasks, the CPU also integrates GNA 3.0 and DL Boost (via AVX2). Quick Sync in version 8 is the same as in the Rocket Lake CPUs and supports MPEG-2, AVC, VC-1 decode, JPEG, VP8 decode, VP9, HEVC, and AV1 decode in hardware. The CPU only supports PCIe 4.0 (x8 for a GPU and two x4 for SSDs).
The integrated graphics adapter is based on the Xe-architecture and offers 96 EUs (Execution Units) operating at up to 1.4 GHz.
Performance
The average 12800H in our database matches the Ryzen 9 6900HS and the Core i9-11900H in multi-thread performance. Which is fairly impressive, as of mid 2022.
Thanks to its decent cooling solution and a long-term CPU power limit of 70 W, the ZBook Studio 16 G9 is among the fastest laptops built around the 12800H that we know of. It can be about 70% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.
Power consumption
This Core i7 series chip has a "minimum assured" power consumption of 35 W, with 45 W being its Base power consumption. The maximum Intel-recommended Turbo power consumption sits at 115 W.
The i7-12800H is built with Intel's fourth-gen 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
Intel Core i5-11400T
► remove from comparison
The Intel Core i5-11400T is a power-efficient six-core desktop processor based on the new Rocket Lake architecture, which was introduced in March 2021. The processor clocks with a base clock of only 1.3 GHz and reaches an all-core boost of 3.7 GHz under load. Intel also gives the Rocket Lake processors the Hyperthreading feature, which allows the i5-11400T to process up to 12 threads simultaneously. As known, the Intel Core i5-11400F is manufactured in the 14 nm process. Nevertheless, many changes have been made with the Rocket Lake architecture, which is also reflected in the performance compared to the Comet Lake.
Performance
Compared to the Intel Core i5-10400T, the Core i5-11400T offers a significantly better IPC. This can be seen clearly in the single-core benchmarks. The multi-core performance also benefits from the better IPC compared to Comet-Lake. A performance increase of up to 20 percent can be expected.
Graphics
The processors integrates a Intel UHD Graphics 730 iGPU that features 24 EUs clocked at 350 - 1200 MHz.
Power consumption
The TDP turns out relatively low with 35 watts. This is the PL1 value. For Turbo, the Intel Core i5-11400T offers a higher TDP of up to 84 watts with PL2. However, this may only be applied for a maximum of 28 seconds (dew).
Intel Core i5-11600K
► remove from comparison
The Intel Core i5-11600K is a high-end desktop CPU based on the Rocket Lake architecture. The CPU offers 6 cores and 12 threads clocked at 3.9 - 4.9 GHz (Turbo Boost 2.0 only). Using all cores, the CPU can clock up to 4.6 GHz.
The TDP is rated at 125 Watt (PL1, power limit sustained load) but the PL2 is set to around 250 Watt for short term boosts (up to 56 seconds).
The Sunny Cove processor cores (known from the Ice Lake mobile CPUs) offer larger caches and an improved IPC (up to 19%). Furthermore, the chip also includes (partly) integrated WiFi 6E and Thunderbolt 4. The platform supports PCIe 4.0 and Intel DL Boost for AI acceleration.
Thanks to the faster core architecture, the 11600K can beat the old i5-10600K by around 20 percent. Therefore, the i5-11600K is a good mid range choice for gaming.
The faster Rocket Lake-S CPUs also integrate a new Intel UHD Graphics 750 that is based on the current Intel Xe architecture (e.g. mobile Tiger Lake) and offers 32 EUs. In the 11600K, the GPU is clocked from 350 - 1300 MHz.
The CPU is manufactured on the old 14nm process like the Comet Lake predecessors. The power consumption is not as high, as the Core i9-11900K, but can't come close to the power efficient Ryzen 5 5600X.
