MacBook Pro 2018 4GB Graphics: Radeon Pro 555X vs 560X Explained
MacBook Pro 2018 4GB graphics: This Kenya-specific guide explains practical buying decisions with manufacturer-supported information, highlighting what still must be checked on a real used or refurbished unit. Infinite Tech’s priority is accurate specifications, transparent condition and current WooCommerce prices—not unverified claims or imaginary benchmarks.
Technical facts and purchase decisions
‘4GB graphics’ is incomplete
Apple’s MacBook Pro 15-inch 2018 specification lists Radeon Pro 555X 4GB GDDR5 with the 2.2GHz Core i7 base and Radeon Pro 560X 4GB GDDR5 in other configurations. Optional Radeon Pro Vega 16 or 20 had 4GB HBM2. The memory figure alone cannot identify performance.
Automatic graphics switching
These Macs also use Intel UHD Graphics 630 and can switch automatically for power-saving tasks. A hardware report should identify the actual discrete Radeon GPU. A listing that states only ‘4GB’ loses essential buying information.
Video and design needs
The 555X, 560X and Vega options differ in architecture and performance; modern editing software can also be constrained by OS compatibility. Do not advertise a 2018 model as fully supported for current software without checking the application’s version requirements.
What to inspect
Look at About This Mac/System Information, confirm 16GB RAM, 512GB SSD and exact GPU, then test battery, keyboard, cooling and charging ports. Ask for written warranty and current machine condition.
| Apple 2018 15-inch graphics option | Graphics memory | What to verify |
|---|---|---|
| Radeon Pro 555X | 4GB GDDR5 | Exact model in System Information |
| Radeon Pro 560X | 4GB GDDR5 | Correct installed GPU |
| Optional Radeon Pro Vega 16/20 | 4GB HBM2 | Optional configuration, not standard on every machine |
Quick buying matrix
| Buyer concern | How to evaluate |
|---|---|
| Software and security | Confirm supported OS, current application versions and required licences. An unsupported older device can have substantial security limitations. |
| Performance | Use exact CPU suffix, installed memory, SSD and GPU model, not the name of the laptop alone. |
| Mobility | Test battery report, charger, screen usability, keyboard and ports on the physical unit. |
| After-sale confidence | Get written warranty, clear cosmetic grade, receipt and return terms before payment. |
Six checks to perform before paying
- Identify the full machine model and CPU model using BIOS or system information.
- Match the manufacturer documentation to the model, not just the seller’s marketing phrase.
- Confirm the currently installed RAM, SSD and GPU memory category.
- Examine battery health, screen, touch, keyboard, camera, ports and charger.
- Verify OS and software security compatibility and previous-owner account status.
- Check the live price, exact stock configuration and written warranty.

Frequently asked questions
Can I trust the CPU label on a reseller listing?
Use the exact CPU model read from the device and compare it with manufacturer support records; vague labels can be misleading.
Does a manufacturer specification prove the hardware inside my used laptop?
No. It establishes what was officially offered, not every component currently installed after refurbishing.
Should I buy a used laptop only because it is inexpensive?
Consider software compatibility, security updates, battery health, physical condition and the cost of replacement parts.
Does Infinite Tech guarantee the availability shown in this guide?
No. This guide links to available product information but does not establish current physical stock. Call to confirm before visiting or paying.
