Intel Core i7-12800HX - 16-core Alder Lake-HX processor already tested

Intel Core i7-12800HX – 16-core Alder Lake-HX processor already tested

It didn’t take long for the first review of Intel’s new high-end laptop processor, because practically the day after the announcement of the Alder Lake-HX series, a test of the 16-core Core i7-12800HX model appeared on the Chinese Golden Pig upgrade package platform.

The Alder Lake-HX series is the spiritual successor to the Tiger Lake-H45, but for one reason only. Unlike the Alder Lake-P, which comes with an integrated chipset, the HX series requires an additional I/O chip (the HM670 chipset). This one expands the number of PCIe lanes for the GPU, storage, and peripherals. The HX CPU itself has 16 lanes of Gen5 for the GPU and 4 lanes of a Gen4 SSD. This extends with an additional 16 Gen4 and 12 Gen3 lines across the chipset. This is evidenced by the image below, which also shows the NVIDIA GN20-E6 GPU (RTX 3070 Ti):

A test of the 16-core Intel Core i7-12800HX processor appeared on the Chinese Golden Pig upgrade package platform.

Due to the fact that this is the first time that we can take a closer look at the processor of the HX series, it is worth checking if there are any changes in the package compared to desktop counterparts. The BGA chassis (the same size as the LGA) is 2.2mm thinner and as the photo confirms, some of the capacitors are placed differently, but the CPU bones seem to be exactly in the same place.

The review covers two identical Lenovo Y9000P laptops with the same GeForce RTX 3070 Ti graphics card (125-150W TGP) and the same memory configuration (DDR5-4800). The comparison includes an Intel Core i7-12700H (14 cores Alder Lake-P) and a Core i7-12800HX (Alder Lake-HX), a 16-core processor (this is the first time we’ve had such a configuration in a regular laptop) . However, these are not the best CPUs in their series, but models somewhere in the middle of the range. However, it should be noted that the 12700H has PL1 and PL2 (power limits) set to 115W and 135W, while the 12800HX is set to 125W and 175W respectively.

The Core i7-12800HX processor delivers nearly identical single-core performance in CPU-related tests, while the multi-threaded score is on average 15% higher, which shouldn’t be surprising considering there are two ultra-high-performance P cores.

There are no significant differences in games, as both processors work more or less the same. In fact, Intel’s novelty is only 2.56% better at premium addresses (AAA), which are practically on the verge of a scaling error.
