Lenovo ThinkPad T15 series guide
Lenovo ThinkPad T15 — 3 models, 2019–2021, from $373 to $686.
Lenovo ThinkPad T15 — 3 models in the used-laptop catalog , spanning 2019 to 2021 , priced from $373 to $686 . This guide covers the configuration spread across the line and which setups are worth buying in 2026.
Where the ThinkPad T15 line stands in 2026
Lenovo's 15.6-inch mainstream business workhorse of the 2019–2021 window: 3 models in our catalog, priced $373 to $686 with a median of $529, all listed and all in the classic 1.75–1.81 kg T-format with RAM ceilings of 48 to 64 GB. The T15 line paired U-series CPUs with small GeForce dGPUs — a light-graphics formula that made it a "does everything, quietly" corporate standard.
The configuration spread
Core i7 leads the recorded CPU configurations (4 to Core i5's 2) — the two 2019 rows run the same i7 10510U, and the 2021 Gen 2 moves to the i5 1135G7. Every row carries a small GeForce card: MX330 in the 2019 pair (with and without the 2GB marking in our data) and the MX450 2GB in the Gen 2 — modest dGPUs that exist for display headroom and light creative work, not gaming. RAM options reach 16–32 GB on the Gen 2 row.
Price versus age
The ladder has a wrinkle worth more than the ladder itself: the two 2019 rows — same Core i7 10510U, same MX330 class — list at $373 and $529, a $156 gap between machines our data cannot distinguish on silicon. That is listing-condition spread, not spec spread, and it means the cheaper of the two is the obvious starting point. The 2021 Gen 2 at $686 asks $157–313 more for a newer platform but a nominally lower CPU tier — the honest read is that year buys the Tiger Lake refresh, not more power.
Which one to buy
The value row is the Lenovo ThinkPad T15 Gen 1 (2019, $373, Core i7 10510U + GeForce MX330) — identical silicon to its $529 sibling and the roster's cheapest entry into the format. The ThinkPad T15 Gen 2 (2021, $686, Core i5 1135G7 + GeForce MX450 2GB) is the pick if the newer platform and warranty-era matter — its MX450 is the strongest graphics in the bucket. The second 2019 row ($529) is only worth it if its specific condition beats the cheaper twin. None of these is a gaming machine; all are solid office-plus-docking candidates.
Bottom line
Across the roster the profile is mid-era business competent: best CPU median 43.7, best GPU median 24, performance index 45.9, USComp Score 46, and exactly 1 game clearing recommended settings at the median configuration — the small-GeForce formula stated in one number. Gaming index 17 confirms it. Portability 46, mobility 41 and energy efficiency 70.4 are middling; reliability 29 is the figure to weigh before buying. The summary: a sensible $373–686 lane for the classic big-screen ThinkPad — start at the $373 twin and pay more only for the 2021 refresh.
