Performance scores
A 2022 ThinkBook with modern silicon, priced above its class
The Lenovo ThinkBook 15 G4 IAP (2022) pairs an Intel Core i7 1255U with 64GB of RAM at $495 — 66% above the business-class median of about $297, a placement the verdict labels premium-priced for the class. The silicon is genuinely current-generation: a 10-core Alder Lake processor that handles everyday and moderate compute with ease. What the price does not buy is a discrete GPU.
Current CPU plus pro-tier memory
The i7 1255U is one of the newer processors in this price neighborhood, and with 64GB of RAM (60% above the class median, top quartile) the machine has both the compute and the memory for serious office work, development and multitasking. For a buyer whose workload is CPU- and RAM-bound — spreadsheets, code, containers, heavy browser sessions — this configuration will feel quick for years.
What the premium does not include
Graphics remain off the menu: no discrete card on file (score zero against a class median of 3.84), no game capability flags surviving. The verdict's leading weakness is exactly that. At $495 the buyer is paying a top-of-class price for a machine whose visual capability is integrated-only — worth weighing against cheaper neighbors that trade memory for a modest dGPU.
A recent-machine depreciation pace
From a $1300 base the ThinkBook has come down to $495, about 10% per year, with a projected $401 in two years — the fastest curve shape in its neighborhood. The premium entry price means the two-year dollar loss is larger than the class average; buyers should plan accordingly.
Business-class neighbors
Pricier alternatives include the EliteBook 1040 G9 ($536) and Dell Latitude 5450 ($569); cheaper ones include the ThinkBook 16 G6 ($466) and ThinkBook 15 G2 ITL ($436). Both cheaper Lenovo options keep large RAM configurations for less money — the G4 IAP's premium rests on its newer CPU generation.
Bottom line
The ThinkBook 15 G4 IAP at $495 is a modern-CPU, 64GB-RAM office machine priced above its class. If the newest silicon and memory capacity are the priorities, the premium is defensible; if balance matters more, cheaper neighbors with similar RAM undercut it. Graphics claims are absent — that axis stays off the table at any price.
