Intel Core Ultra 7 155H

The Intel Core Ultra 7 155H presented in December 2023 is a powerful processor from Intel's new Meteor Lake generation.

Technical data and performance of the Intel Core Ultra 7 155H
The Intel Core Ultra 7 155H has six performance cores that support hyperthreading and eight efficiency cores. In the new tile/chiplet design, two additional low-power efficiency cores are also installed on the low-power island, which then take over in idle mode and at low load, thus helping to save power. The Intel Core Ultra 7 155H has a total of 22 threads and 24 MB L3 cache, which can be used to quickly retrieve and process frequently used data. Intel specifies the power consumption at 28 watts, in low-power mode the CPU only requires 20 watts, but then only clocks at 700 MHz. In boost mode, the consumption can increase to up to 115 watts, but then the CPU also clocks at up to 4.8 GHz. In comparison: The Intel Core Ultra 9 185H clocks up to 5.2 GHz with the same cores and the same consumption.

Integrated graphics card and additional functions
The Intel Core Ultra 7 155H uses an Intel Arc iGPU with eight cores. The new iGPU is based on the Xe LPG architecture, an efficiency-focused adaptation of the architecture of dedicated Arc GPUs. Just as the design of the CPUs within the Meteor Lake H series is largely the same, the iGPUs are also very similar. An Intel Arc 8C GPU 2.25 GHz is integrated in the Intel Core Ultra 7 155H, which has eight ray tracing units, eight samplers and four pixel backends in addition to the eight Xe cores and is manufactured using the 5nm process. According to Intel, the performance has improved significantly compared to the Intel Iris Xe Graphics G7 96 EUs. As a result, everyday tasks pose no problems for the new iGPU and even light video and image editing as well as gaming at low detail levels should not overtax it.

The Intel Core Ultra 7 155H supports WiFi 7 and Thunderbolt. The memory controller is identical to that in the Intel Core Ultra 9 185H and supports up to 96 GB DDR5-5600 or up to 64 GB LPDDR5x-7467 RAM. Intel Core i7-14700HX and Intel Core i9-14900HX can be installed with up to 192 GB DDR-5600.

Conclusion
All in all, the Intel Core Ultra 7 155H is a powerful processor that can be used for gaming and creative work. It is a good choice for anyone looking for a powerful and energy-efficient CPU.
