Choosing the right laptop or desktop is crucial for smooth performance and productivity.
Should I go for a heavy graphics card or a powerful processor?
What is the ideal RAM required?
Will it last for a minimum of 5 years?
1. Laptop VS Destop
| Feature | Laptop | Desktop |
|---|---|---|
| Portability | Highly portable – ideal for students & professionals on the go. | Not portable – best for fixed workspaces or offices.Heavy tasks users |
| Price | Higher cost per performance – good for basic to mid-level CAD tasks. | More value for money – better specs at lower prices. |
| Maintenance | Harder to maintain – limited access to internal components. | Easier to maintain – open build allows quick fixes and cleaning. |
| Upgradability | Limited upgrades – RAM, SSD sometimes expandable, GPU not upgradeable. | Fully upgradeable – easily swap CPU, GPU, RAM, storage, and more. |
2. Laptop Buying Guide for Designing– Budget-Wise
1. Budget: ₹20,000 – ₹35,000
| For | Type | Processor | RAM | Storage |
|---|---|---|---|---|
| AutoCAD, Basic 3D Modelling (SolidWorks, Revit & 3Ds Max, SketchUp) | Refurbished / Entry-level New | Intel Core i5 10th Gen (6 cores, 12 threads) or equivalent AMD Ryzen 5 | 16 GB DDR4 | 256 GB NVMe SSD |
📌 Use Cases:
- 2D drafting with AutoCAD
- Light 3D modeling with SolidWorks, SketchUp
- Basic usage of Revit and 3Ds Max
2. Budget: ₹40,000 – ₹60,000
| For | Processor | RAM | Graphics | Storage |
|---|---|---|---|---|
|
AutoCAD + Advanced 3D Modelling + Rendering |
Intel Core i5 12th Gen + or AMD Ryzen 5 5500
6 Cores, 12 Threads |
16 GB DDR4 or DDR5 RAM |
2-4 GB Dedicated GPU For rendering Better visuals & stability |
256 GB NVMe SSD Fast boot & load times |
📌 Use Cases:
- Advanced 3D modeling in SolidWorks
- BIM workflows with Revit
- 3D rendering & visualization in 3Ds Max and SketchUp
3. Budget: ₹60,000 – ₹90,000
| For | Processor | RAM | Graphics | Storage |
|---|---|---|---|---|
|
AutoCAD + 3D Modeling & Good Rendering |
Intel Core i5/i7 14th Gen
or AMD Ryzen 7 7500+ 8–16 Performance Cores |
24 GB DDR5 RAM Perfect for large projects |
4 to 8 GB Dedicated GPU (RTX Series) Supports ray tracing & lighting |
1 TB NVMe SSD Fast access to large files |
📌 Use Cases:
- Big & complex 3D modeling in SolidWorks
- Large-scale BIM projects using Revit
- Photorealistic rendering in 3Ds Max and SketchUp
- Complex assemblies and simulations in engineering workflows
- Vray, Lumion, Keyshorts rendering in less time

4. Budget: ₹1,00,000+ ❌ Not Recommended:
While laptops above ₹1 lakh may offer high-end specs, they are not cost-effective for most engineering design tasks.
| Issue | Why It’s a Problem |
|---|---|
| High Cost |
Paying more than ₹1 lakh for a laptop doesn't always mean better performance. You get fewer upgrades and less power compared to a desktop at the same price. |
| Poor Value | For complex rendering or simulation in SolidWorks, Revit BIM, and 3Ds Max, a desktop offers far better value. |
| Limited Upgrades |
Even high-end laptops are hard to upgrade. Desktops let you swap out RAM, GPU, CPU, and storage as needed. |
| Cooling & Performance |
Laptops overheat faster under load. Desktops have better cooling and deliver consistent performance during long design sessions. |
📌 Recommendation:
- Avoid spending over ₹1 lakh on a laptop for CAD or BIM work.
- Use that budget for a powerful desktop PC instead — it will last longer and perform better.
