Lenovo X1 Carbon vs Lenovo T590 in Kenya: Detailed Feature Comparison and Which One Should You Buy?
If you’re looking for a reliable Lenovo ThinkPad in Kenya, two models worth considering are the Lenovo ThinkPad X1 Carbon and Lenovo ThinkPad T590.
Both are business-class laptops built around Intel Core processors, fast SSD storage, excellent keyboards and strong productivity performance. However, they are designed for slightly different users.
The X1 Carbon prioritizes portability, premium construction and mobility, while the T590 gives you a larger 15.6-inch screen, a numeric keypad and better RAM upgradeability.

So, is the extra KSh 2,500 for the X1 Carbon worth it? Let’s break it down

1. Lenovo ThinkPad X1 Carbon vs T590: Design and Portability
This is where the X1 Carbon immediately separates itself from the T590.
The ThinkPad X1 Carbon 8th Gen is designed as an ultraportable business laptop. Its lightweight construction makes it easier to carry between the office, home, meetings, campus or travel destinations.
By comparison, the T590 is a larger 15.6-inch machine weighing approximately 1.75kg.
That extra size isn’t necessarily a disadvantage.
In fact, the larger chassis gives the T590 room for a bigger display and a full-size keyboard with a numeric keypad.
Winner: X1 Carbon
If portability is your priority, the X1 Carbon is the obvious choice.
2. Display: 14 Inches vs 15.6 Inches
The T590 gives you more screen real estate with its 15.6-inch display.
Depending on configuration, the T590 can have:
- 15.6-inch FHD IPS
- 15.6-inch FHD touchscreen
- 15.6-inch UHD display
- Up to 500 nits on the UHD configuration
Lenovo also offered multiple display configurations for the X1 Carbon 8th Gen, including:
- 14-inch FHD
- 14-inch FHD touchscreen
- 14-inch FHD PrivacyGuard touchscreen
- 14-inch WQHD
- 14-inch UHD 4K
The higher-end X1 Carbon display can reach 500 nits, while the 4K configuration supports Dolby Vision HDR.
T590 advantage
The 15.6-inch display is excellent for:
- Excel
- Accounting
- Research
- Split-screen work
- Large documents
- Watching content
X1 Carbon advantage
The 14-inch screen gives you a better balance between workspace and portability.
Verdict: Depends on your needs
Large-screen productivity → T590
Portable productivity → X1 Carbon
3. Processor Performance
The two laptops can be surprisingly close in performance because their processor options overlap.
The T590 was available with 8th Gen Intel Core i5 and i7 processors. Its Core i7 options include the i7-8565U and i7-8665U, both quad-core, eight-thread processors.
The X1 Carbon 8th Gen was also offered with Intel Core processors, including configurations reaching 10th Gen Core i7.
For the particular ValueHub configurations you’re comparing, both are Core i7 systems with 16GB RAM and 512GB SSD.
That means everyday tasks such as:
- Microsoft Office
- Google Chrome
- Research
- Zoom
- Programming
- Accounting
- Business software
- Multitasking
should be handled comfortably on either machine, assuming the laptops are in good condition.
Winner: Tie for the specified configurations
The processor generation and exact CPU model matter more than simply seeing “Core i7” on the laptop.
4. RAM: The T590 Has a Major Advantage
Here’s an important difference that buyers sometimes overlook.
The X1 Carbon 8th Gen has soldered LPDDR3 memory with no RAM sockets. Lenovo lists configurations of 8GB or 16GB.
The T590 is much more flexible.
It has one soldered memory module plus one DDR4 SO-DIMM slot. Lenovo documents configurations up to 40GB or 48GB depending on the onboard memory configuration.
That makes the T590 particularly attractive if you plan to upgrade the laptop later.
Winner: T590
For buyers thinking about long-term upgradeability, the T590 has the edge.
5. Storage: Both Offer Fast SSD Performance
Both models support SSD storage, making them significantly more responsive than older ThinkPads using mechanical hard drives.
Your ValueHub configurations provide:
T590: 512GB SSD
X1 Carbon: 512GB SSD
A 512GB SSD gives you plenty of space for:
- Documents
- Photos
- Software
- School projects
- Business files
- Videos
- Applications
The T590 supports M.2 SSD configurations, including PCIe NVMe options, with Lenovo documenting support up to 2TB for the M.2 2280 configuration.
The X1 Carbon 8th Gen also supports M.2 PCIe NVMe SSD storage up to 2TB.
Winner: Tie
Both are excellent with a 512GB SSD.
6. Graphics Performance
Neither of these machines is primarily a gaming laptop.
The X1 Carbon 8th Gen uses Intel UHD integrated graphics.
The T590 can also use Intel UHD Graphics, but selected configurations were available with an NVIDIA GeForce MX250 with 2GB GDDR5.
Therefore, if you find a T590 with the MX250, it can have an advantage for certain graphics workloads.
For normal office use, however, integrated graphics are perfectly adequate.
Winner: T590, if equipped with MX250
7. Keyboard and Numeric Keypad
ThinkPads have one of the strongest reputations for keyboard quality in the business-laptop market.
The X1 Carbon delivers the classic ThinkPad typing experience in a compact chassis.
The T590 takes it one step further for users who work with numbers by including a numeric keypad. Lenovo’s specifications list a six-row spill-resistant keyboard with a numeric keypad.
This makes the T590 especially useful for:
- Accountants
- Finance students
- Data entry
- Excel users
- Business owners
- Inventory management
Winner: T590
For typing alone, both are excellent. For numerical work, the T590’s number pad is a big advantage.
8. Battery and Mobility
The X1 Carbon 8th Gen was designed with mobile professionals in mind.
Its compact design makes it easier to carry throughout the day, while Lenovo’s specifications include Rapid Charge support.
The T590 uses a larger 57Wh battery, while the X1 Carbon 8th Gen uses a 51Wh integrated battery.
However, don’t judge battery life solely by battery capacity.
Processor configuration, display resolution, brightness, Windows settings, workload and—especially with older machines—the actual health of the battery all affect real-world runtime.
Winner: X1 Carbon for mobility
9. Ports and Connectivity
The T590 provides a practical selection of ports, including:
- USB-A ports
- USB-C
- Thunderbolt 3
- HDMI
- Ethernet
- MicroSD card reader
- Headphone/microphone combo jack
- Docking connector
Selected versions can also have a Nano-SIM slot for WWAN connectivity.
The X1 Carbon 8th Gen also offers a strong business connectivity package, including USB-A, USB-C/Thunderbolt 3, HDMI and a headphone/microphone combo jack.
Winner: T590
The larger chassis gives it an advantage for users who prefer having more physical connectivity.
10. Security Features
Both machines belong to Lenovo’s ThinkPad business family, so security receives considerable attention.
Depending on configuration, the X1 Carbon 8th Gen can include features such as:
- Fingerprint reader
- ThinkShutter camera privacy cover
- TPM security
- Optional IR camera
- Windows Hello support
The T590 also offers business-focused security features, including TPM, fingerprint authentication and ThinkShutter on applicable configurations.
Winner: Tie
Both are well suited to professional environments.
X1 Carbon vs T590 for Students in Kenya
For students, the answer depends on how the laptop will be used.
A student who walks around campus with a laptop every day may appreciate the X1 Carbon’s lightweight design.
It is easier to place in a backpack and carry between lectures, libraries and accommodation.
On the other hand, the T590’s 15.6-inch screen is excellent for research, spreadsheets and working with multiple windows.
The T590 also gives you RAM upgradeability, which can be useful as software requirements increase.
Our student pick: X1 Carbon for portability
Our productivity pick: T590 for screen size and upgradeability
