When choosing between the Dell Inspiron 15 3511 and the Lenovo ThinkPad X1 Titanium Yoga, consider your primary needs. The Dell Inspiron offers more storage and is significantly less expensive, making it a practical choice for general use and those who want to prioritize budget friendliness. It has a larger screen, but is heavier and thicker, which might not be ideal for frequent travel. On the other hand, the Lenovo ThinkPad X1 Titanium Yoga is pricier but provides better build quality, a higher resolution in a compact design, and is much lighter and slimmer, thus offering superior portability. It is also a 2-in-1 convertible, doubling as a tablet, which appeals to those needing versatility for presentations or creative work. However, it comes with less storage out of the box. If performance in a portable and flexible form factor is crucial and you're willing to invest more, the Lenovo might be the better option. Otherwise, for standard needs and where cost savings are important, the Dell could be sufficient. Give Feedback

The Lenovo ThinkPad X1 Titanium Yoga has a better screen than the Dell Inspiron 15 3511 for general use, gaming and AI, and engineering and design.
For general use, the Dell Inspiron 15 3511's screen is adequate due to its resolution and brightness, while the Lenovo ThinkPad X1 Titanium Yoga's higher resolution and brighter display provide a more comfortable and sharp viewing experience.

The Dell Inspiron 15 3511 and Lenovo ThinkPad X1 Titanium Yoga are both good for general use.
The Dell Inspiron 15 3511, with more storage and RAM, a larger screen, and a strong CPU, is well-suited for general use due to its ample processing power and display size, although it is heavier and less portable. The Lenovo ThinkPad X1 Titanium Yoga, on the other hand, offers a high-resolution touchscreen with superior brightness and color coverage, a lighter and thinner build for better portability, and longer battery life, making it ideal for use on the go and in varied environments, but with half the storage and RAM compared to the Dell.

The Dell Inspiron 15 3511 and Lenovo ThinkPad X1 Titanium Yoga are both only fair for gaming and AI.
The Dell Inspiron 15 3511 and Lenovo ThinkPad X1 Titanium Yoga are considered fair for gaming and 3D due to their integrated Intel Iris Xe graphics, which can handle casual gaming but aren't as powerful as dedicated gaming GPUs. Both have a screen refresh rate of 60Hz, which is sufficient for everyday use but less optimal for fast-paced games that benefit from higher refresh rates.

Zachary Cuevas | November 2021
"The Dell Inspiron 15 3000 (3511) is a solid, if unremarkable, 15-inch budget laptop. It improves on many of the issues we had with the previous 3505 model, and with the inclusion of Windows 11, the 3511 is already a step above its competition. The lack of a USB-C port, the subpar speakers, and the dim display are drawbacks to factor in, but it's still one of the better 15-inch budget laptops on the market, especially when you consider it's under $400."

"The ThinkPad X1 Titanium is a showcase of what Lenovo thinks business computing will look like in the near future. People want thinner, lighter laptops with high-quality screens and enough computing power to get their work done. The X1 Titanium achieves these goals with some controversial but innovative design choices, including a redesigned keyboard and a pared-down port selection."
