Which is the Best Graphics Card: 4GB AMD Radeon R7 M270 vs 2GB NVIDIA GeForce 840M
When it comes to choosing the best graphics card, particularly for laptops, the decision often hinges on several key factors such as clock speed, memory capacity, display and rendering quality, and overall performance. Let's break down the differences between the 4GB AMD Radeon R7 M270 and the 2GB NVIDIA GeForce 840M to help you make an informed decision.
Core Specifications and Performance
1. Clock Speed: The Radeon R7 M270 features a clock speed of 825 MHz, while the 840M operates at 1029 MHz. This difference means that the 840M will run slightly faster, especially for older games and applications that do not require high memory.
2. Memory Capacity: The Radeon R7 M270 boasts 4GB of VRAM, whereas the 840M only has 2GB. While 2GB may seem limiting, it is often sufficient for most users, particularly those who do not engage in high-end gaming or demanding graphical tasks.
Performance Analysis
1. Display and Rendering Quality: When it comes to display and rendering quality, the 840M generally outperforms the R7 M270, providing a superior visual experience by about 10-15%. However, this advantage is more pronounced in lower resolution displays and settings.
2. Newer Games and DirectX Compatibility: The R7 M270 has better directX 12 support, a larger memory bus (128-bit), and more memory (4GB). This combination makes it more capable of handling newer games and generally performs well at low to mid settings. The 840M, despite its higher clock speed, struggles with even low settings in recently launched games, particularly those developed after 2014-2015.
Practical Considerations
1. Wattage and Power Consumption: The R7 M270 requires less wattage, which is beneficial for laptops with limited power supply. However, lower wattage can sometimes translate to reduced efficiency in overall processing power.
2. Price, Availability, and Service: Both cards have similar performance levels, making the decision somewhat subjective. Factors such as price, availability, and after-sales service become important. If cost is a significant factor, the 840M is a more affordable option. Availability can also differ depending on the local market, and service quality will vary based on the brand and vendor.
Conclusion
In the grand scheme of things, the 840M's higher clock speed can provide a slight edge in performance, especially with older games and applications that do not require high memory. However, the R7 M270's better support for newer games, higher memory capacity, and directX 12 support make it a more versatile and capable choice for modern gaming and graphical tasks.
Ultimately, the best graphics card for you depends on your specific needs and budget. If you are a gamer looking to future-proof your system, the R7 M270 is likely the better choice. However, if you are prioritizing lower prices and current performance with older games, the 840M can be a more compelling option.
