Laptop Spec Decoder: what does this laptop spec mean?
Paste a laptop model, a processor code or a whole OLX ad title. You get the processor generation and year, what the letters mean, whether Windows 11 is supported, what the RAM, storage and screen mean for you, and the questions to ask before you pay.
The short answer
A laptop processor name tells you its age and power. In Core i5-8350U, "i5" is the tier, "8" is the generation (8th gen, about 2017-2019), "350" is the model and "U" means a low-power chip for thin laptops. Intel 8th gen and newer are on Microsoft's Windows 11 list; 7th gen and older are not.

How to read an Intel processor name
Take Core i5-8350U. i5 is the tier (i3 entry, i5 mid-range, i7 upper mid-range, i9 top). 8 is the generation. 350 is the model within that generation: higher is a little faster. U is the type of chip. From 10th gen the generation takes two digits: i5-10210U, i5-1135G7, i7-1255U, i9-13900H. After 14th gen Intel moved to "Core Ultra" names such as Core Ultra 7 155H.
| Letter | What it means |
|---|---|
| U | Low power (about 15 W). Thin and light laptops, good battery life. The most common letter in business laptops. |
| G1 / G4 / G7 | 10th and 11th gen low-power chips with Iris graphics. G7 has the strongest built-in graphics, G1 the weakest. |
| P | 12th and 13th gen mid-power chips (about 28 W), between U and H. |
| H / HQ / HK | High performance for bigger, gaming and workstation laptops. Faster, warmer, shorter battery life. |
| HX | The most powerful laptop chips, close to desktop chips. Gaming laptops and workstations. |
| Y | Very low power for fanless or very thin laptops. Quiet, but slower than U. |
| M | Older (2nd-4th gen) name for a normal laptop chip, e.g. i5-2520M or i5-4300M. |
| V | Core Ultra 200V (Lunar Lake): memory sits inside the chip package, so RAM cannot be upgraded. |
AMD Ryzen and Apple M chips
In a Ryzen name like Ryzen 5 5600U, the 5 after "Ryzen" is the tier and the first digit of the number is the series (5000 = 2021). The letter works like Intel's: U for thin laptops, H and HS for performance, HX for the top gaming chips. Two traps: in the 5000 series, the 5300U, 5500U and 5700U use the older Zen 2 design; and in the 7000 series the last two digits show the design (7x20 Zen 2 up to 7x40 Zen 4).
Apple's M1 (2020), M2 (2022), M3 (2023) and M4 (2024) chips are very efficient. Pro and Max versions add more CPU and graphics cores. Memory and SSD are fixed when the Mac is made, so a used MacBook cannot be upgraded later.
How to read business laptop model numbers
Dell Latitude
First digit = tier (3 budget, 5 mainstream, 7 premium, 9 flagship). Second digit = screen size (2 = 12.5", 3 = 13.3", 4 = 14", 5 = 15.6"). Last two digits = model step; higher is newer.
Example: Latitude 7490 = premium, 14-inch, newer than a 7480.
HP EliteBook / ProBook
EliteBook is HP's premium business line, ProBook the mainstream one. The middle digit is the screen size (3 = 13.3", 4 = 14", 5 = 15.6"). G plus a number is the generation.
Example: EliteBook 840 G5 = 14-inch, 5th generation.
Lenovo ThinkPad
Letter = line (T workhorse, X small and light, X1 premium, E and L value, P workstation). Older names: first digit = screen size (T480 = 14"). From 2020 the number is the screen size in inches and "Gen" counts the yearly update.
Example: T480 = 14-inch, older than T490; T14 Gen 2 = 14-inch, 2nd version.
Apple MacBook
The chip (M1, M2, M3, M4) and year matter more than the name. Pro and Max chips add CPU and graphics cores. RAM and SSD cannot be upgraded later.
Example: MacBook Air M1 = 2020, fanless, 8GB or 16GB memory.

Questions about laptop specs
How do I find out which generation my Intel laptop processor is?
Look at the number after i3, i5, i7 or i9. With four digits, the first digit is the generation (i5-8350U = 8th gen). With five digits, or four digits starting with 1, the first two digits are the generation (i5-10210U = 10th gen, i5-1135G7 = 11th gen, i5-1235U = 12th gen). Three digits (i5-520M) means 1st gen. On Windows, open Settings > System > About to see the exact name.
What does the U, H or G7 at the end of a processor name mean?
U means a low-power chip for thin laptops with good battery life. H, HQ and HX are high-performance chips for bigger, gaming and workstation laptops. G1, G4 and G7 are 10th and 11th gen low-power chips with Iris graphics; G7 has the strongest graphics. P is a mid-power 12th and 13th gen chip.
Is 8th gen still worth buying in 2026?
For office work, study, browsing and light coding, yes: 8th gen U-series i5 and i7 chips have 4 cores (7th gen U chips have 2) and they are on Microsoft's Windows 11 list. At NN Laptops today, 94 used 8th gen laptops are listed; most cost Rs. 60,000 to Rs. 97,500, the middle price is Rs. 80,000 and the cheapest is Rs. 39,500. For video editing, heavy software or gaming, look at 11th gen or newer, or a laptop with a dedicated graphics card.
Does my laptop support Windows 11?
Microsoft's official list covers Intel 8th gen and newer and AMD Ryzen 2000 series and newer, along with TPM 2.0 and Secure Boot. 7th gen and older Intel chips are not on the list, with very few exceptions. Our free Windows 11 compatibility checker goes through the full list of requirements.
Why is a Ryzen 5 7520U slower than a Ryzen 5 7640HS if both are 7000 series?
In the Ryzen 7000 laptop series the last two digits show the real design: 7x20 is the older Zen 2 design, 7x30 is Zen 3, 7x35 is Zen 3+, and 7x40 and 7x45 are the newer Zen 4. So a 7520U uses a much older design than a 7640HS, even though both names start with 7.
