Asus ExpertBook Ultra review: One helluva debut for Intel Panther Lake X7

[Redaktion]

Asus and Intel are starting off the year strong with the debut of the Core Ultra X7 358H. Although technically a business-oriented laptop, both graphics performance and performance-per-watt are insane for a 14-inch form factor.

[Say in bits per channel]

AFAIK, LPDDR5X is measured in terms of 16-bit per channel (and LPDDR6 is 24-bit per channel). So, why not state it in terms of bits to make it absolutely clear? In this case you would state it as 128-bit.

128-bit checks out with what is measured by AIDA64.
136528 MB/s (theoretical maximum) = 128 (8[or state octa-channel]*16-bit) * 8533 MT/s / 1000 / 8.

[Say in bits]

Sorry, I meant in bits, not bits per channel, as the bits per channel vary depending whether it's LPDDR5(X) or DDR5.

Actually surprised the battery life isn't better than what it is.

ExpertBook Ultra X7 = 70 Wh/16.1 hr = 4.35 W/hr of wi-fi time
Dell Pro Ryzen 7 350 = 55 Whr/11.8 hr = 4.66 W/hr of wi-fi time
VivoBook S14 OLED HX 370 = 75 Whr/16.5 hr = 4.54 W/hr of wi-fi time

Maybe that tandem OLED is a bigger power hog but I'd thought the 4 LPE cores, TSMC 3nm, and Intel 18 A would obliterate AMD on TSMC 4 nm with no LPE cores in low power wi-fi tasks.
