Memory channelsiCounted in 64-bit channels, as Intel and AMD count them. A DDR5 module has two 32-bit subchannels and makers count it as one channel. A maker that counts narrower channels and states their width is converted by the total bus width, so Qualcomm's 8 channels of 16 bits are 2. A total bus width alone is divided by 64, so AMD's 256-bit interface is 4. The maker's own count goes in the source note.

Socket or packageiDesktop socket, e.g. AM5 or LGA1851. Laptop chips are soldered, so this is the package the maker names, e.g. FP8. When the maker names several packages, in the socket row or the product IDs, list them all separated by commas, such as "FP7, FP7r2".

CPU PCIe lanesiUsable PCIe lanes from the processor, one row per PCIe generation. Lanes that link the CPU to the chipset are not counted. If the maker gives only a total, a review that lists the split may be used, and the source note names it. When the package also holds the chipset, as on Intel Raptor Lake U and H chips, ARK's total includes the chipset lanes. Those are not counted, so the datasheet split is used. On Intel Core Ultra chips, such as Panther Lake, the platform controller or SoC tile is part of the processor, so its lanes count.

2.5GHz7Reviewtomshardware.com/laptops/dell-xps-13-9350-reviewRead 15 October 2026Tom's Hardware review of the Dell XPS 13 (9350), published 12 October 2024, tested in Dell's default out-of-the-box optimized mode with the Core Ultra 7 258V and 32 GB of on-package RAM. In the Cinebench 2024 stress test, run 10 times, the P-cores averaged 2.5 GHz and the E-cores 2.83 GHz. The P-core group is stored, since it has the highest rated clock. The review says the score started at 500 and settled in the 470s, so no single Cinebench result is stored. It gives a CPU package temperature of 73.33 C during the test without saying whether it is the highest or an average, so the stress temperature field is left empty. The clock is for this laptop and its power limits. Other laptops set other limits.
