Intel Core i7-12650HX vs Intel Core i9-14900HX vs Intel Core i9-12950HX

Intel Core i7-12650HX

► remove from comparison Intel i7-12650HX

The Intel Core i7-12650HX is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in mid 2022 and offers 6 of the 8 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 2.0 to 4.7 GHz on the performance cluster and 1.5 to 3.3 GHz on the efficiency cluster. The performance of the E-cores should be similar to old Skylake cores (compare with the Core i7-6920HQ). All cores can use up to 25 MB L3 cache. The CPU offers an open multiplicator and therefore the possibility to overclock the CPU cores. Compared to the similar i7-12850HX, the 12800HX does not offer vPro or ECC memory support.

Performance

Due to the similar specs, the performance of the 12650HX should be similar to the Core i7-12700H (14 cores, max 4,7 GHz, 45 W TDP). Thanks to the higher TDP, the sustained performance could be better (if the cooling of the laptop is sufficient). 

Features

The integrated memory controller supports various memory types up to DDR5-4800 and DDR4-3200. 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 supports 48 PCIe lanes consisting of 16 Gen5 (x16 or 2x8), 20 Gen4 and 12 Gen3.

The integrated graphics card is based on the Xe-architecture and offers 32 EUs (Execution Units) operating at up to 1.45 GHz.

The CPU is rated at 55 W base power (157 W PL2). The SoC is manufactured on a 10nm process at Intel, which is known as Intel 7.

Intel Core i9-14900HX

► remove from comparison Intel i9-14900HX

The Intel Core i9-14900HX is a high-end CPU based on the Raptor Lake architecture for large and heavy notebooks. The CPU was introduced at the beginning of 2024 and is a slightly higher clocked variant of the older Core i9-13980HX.

The total of 32 threads are divided into P-cores and E-cores, which we already know from Alder-Lake. Here, 8 performance cores (P-cores) with hyperthreading are used and 16 efficiency cores, so that a total of 32 threads can be processed simultaneously. The P-cores clock from 2.2 GHz (base clock) to 5.8 GHz (single-core turbo) and the E-cores from 1.6 GHz to 4.1 GHz.

Performance

Due to the slightly higher maximum clock rates, the single-core performance of the 14900HX in particular increases slightly compared to the 13980HX. Compared to AMD's top model, the Ryzen 9 7945HX or 7945HX3D the 14900HX comes in just behind (on average in our benchmarks). However, the performance depends on the benchmark and the cooling and is usually very comparable.

Graphics

Like the Intel Core i9-12900HX, the Intel Core i9-14900HX offers an integrated graphics unit. The Intel Iris XE architecture continues to serve as the basis. In terms of performance, however, not much has changed with the Intel UHD Graphics 770.

The 14900HX is manufactured on the improved 10nm FinFET process at Intel (Intel 7 process) and is specified with 55 watts of base power and 157 watts of turbo power.

Intel Core i9-12950HX

► remove from comparison Intel i9-12950HX

The Intel Core i9-12950HX is a high-end mobile CPU for laptops based on the Alder Lake architecture. It was announced in mid 2022 and offers 8 performance cores (P-cores, Golden Cove architecture) and 8 efficient cores (E-cores, Gracemont architecture). The P-cores support Hyper-Threading leading to 24 supported threads when combined with the E-cores. The clock rate ranges from 2.3 to 5 GHz on the performance cluster and 1.7 to 3.6 GHz on the efficiency cluster. The performance of the E-cores should be similar to old Skylake cores (compare with the Core i7-6920HQ). All cores can use up to 30 MB L3 cache. As a HX-variant, the CPU offers an open multiplicator and therefore the possibility to overclock the CPU cores. Compared to the similar i9-12900HX, the 12950HX supports vPro and ECC memory (successor of the Xeon line) but the CPU overclocking is limited.

Features

The integrated memory controller supports various memory types up to DDR5-4800 and DDR4-3200. 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 supports 48 PCIe lanes consisting of 16 Gen5 (x16 or 2x8), 20 Gen4 and 12 Gen3.

The integrated graphics adapter is based on the Xe-architecture and offers 32 EUs (Execution Units) operating at up to 1.55 GHz.

Performance

The average 12950HX in our database is in the same league as the Core i7-13650HX, Core i7-13700HX, Core i9-13900HK, as far as multi-thread benchmark scores are concerned. This is a very fast chip, as of early 2023.

Thanks to its decent cooling solution and a long-term CPU power limit of 82 W, the ThinkPad P16 G1 is among the fastest laptops built around the 12950HX that we know of. It can be 30% faster in CPU-bound workloads than the slowest system featuring the same chip in our database, as of August 2023.

Power consumption

The chip's "minimum assured" power consumption is 45 W. Its Turbo power consumption is not supposed to go over 157 W and its Base power consumption is supposed to be around 55 W. Most laptop makers will probably go for a higher value than 55 W to get better performance.

The i9-12950HX is built with Intel's 4th generation 10 nm process marketed as Intel 7 for average, as of early 2023, energy efficiency.
