Lenovo ThinkPad L15 Gen 4: when the RAM outclasses the engine
The ThinkPad L15 Gen 4 at $886 is this batch's most instructive odd configuration: an Intel Processor U300 — the entry rung of the lineup — paired with an MX550 discrete card and 64GB of RAM. The memory ceiling clears the business-class median of 40 by 60 percent, the graphics score of 49.14 runs 12.8 times the class median of 3.84, and the resulting sheet has no resolved weak axis at all. The U300 is the humble part; everything around it is not.
Where it holds up
The MX550 does the heavy lifting: 49.14 in the mainstream band with a top-quarter placing, translating into a top-band 88 photo-design score (Photoshop minimum cleared) and a mid-band 46 gaming index with recommended-level passes for Overwatch and Grand Theft Auto V plus a measured Far Cry 5 result of 45 frames per second at recommended settings. The 64GB of RAM means the entry CPU will never wait on memory, and the performance index of 65.6 lands high-band — remarkable for the badge. Office reads 91.91 top-band; reliability of 68 runs 60 percent above the median.
Where it falls short
By peer comparison there is no low band, but the configuration's character is worth reading honestly: the U300 is the humblest badge in this batch's business class, and its 64GB of RAM is a specialist's answer to a problem most buyers do not have. Portability of 46.9 is mid-band — the 15-inch chassis sits at desks more than it travels. Value at 53.9 reads mid; the money bought memory and graphics, not badge prestige.
Price and depreciation
$886 is mid-tier business money. No listing history anchors the unit, so the class rate of about 10.62 percent a year is the working number — a gentle drain that suits the machine's steady-utility character.
Alternatives to consider
The E14 Gen 5 (model 1806) at the same $886 pairs the same MX550 with an i3 1315U and 48GB — matching graphics, photo and value figures with a humbler memory ceiling in a smaller frame. The L16 Gen 1 (model 1823) at $1,007 moves to the 125H platform with 64GB but surrenders the discrete card entirely.
Bottom line
Fairly priced for the class. The L15 Gen 4 proves a modest engine surrounded by premium parts can post a high-band performance index and an 88 photo score; buy it for the memory and the card, not the badge on the CPU.
