Which Is Better An Rtx 3070 Mobile 140w Or An Rtx 2080 Desktop

When it comes to graphics cards, the choice between a high-performance mobile GPU like the RTX 3070 (140W) and a desktop behemoth like the RTX 2080 can be a challenging one. Both have their own set of advantages and disadvantages, and the decision ultimately hinges on your specific requirements and preferences.

Performance Showdown

RTX 3070 Mobile (140W)

The RTX 3070 Mobile (140W) is a formidable mobile graphics card known for its raw power. With 140 watts of thermal design power (TDP), it delivers excellent performance in gaming and content creation tasks. Its architecture is optimized for laptops, providing a good balance between power and efficiency.

RTX 2080 Desktop

On the other hand, the RTX 2080 desktop variant is a beast in terms of raw performance. With a higher TDP and more CUDA cores, it outpaces the RTX 3070 in pure computational power. Desktop GPUs also have the advantage of better cooling solutions, allowing them to sustain high clock speeds for extended periods.

Power Consumption

One of the key differences between these two options is power consumption. The RTX 3070 Mobile, despite being a high-end mobile GPU, is designed to operate within the power constraints of a laptop. This means it consumes significantly less power compared to the RTX 2080 desktop, which can draw a substantial amount of electricity.

Portability and Form Factor

When it comes to portability, the RTX 3070 Mobile has the upper hand. Laptops equipped with this GPU are compact and can be carried around easily. In contrast, the RTX 2080 desktop requires a full-sized PC tower, limiting its mobility.

Price Point

Price is always a crucial factor in any purchasing decision. The RTX 3070 Mobile laptops are generally more affordable than building a desktop system with an RTX 2080. However, prices can vary significantly depending on the laptop’s brand and specifications.

Ray Tracing and DLSS Support

Both GPUs support ray tracing and DLSS (Deep Learning Super Sampling) technologies. However, the RTX 3070 Mobile may struggle to deliver ray tracing at ultra-high settings due to its lower TDP.

Content Creation Performance

For content creators, the RTX 3070 Mobile offers excellent performance on the go. It can handle video editing, 3D rendering, and graphic design tasks with ease. The RTX 2080 desktop, though more powerful, lacks the mobility factor.

Gaming Experience

Gamers will appreciate the RTX 2080’s desktop power for running the latest AAA titles at high frame rates. The RTX 3070 Mobile, while capable, might not match the performance of its desktop counterpart.

Thermal Management

Desktop GPUs typically have superior cooling solutions compared to laptops, allowing them to maintain lower temperatures during demanding tasks. This can lead to more consistent performance over extended gaming or rendering sessions.


Desktop systems have the advantage of being highly upgradeable. You can easily swap out components like the GPU, CPU, and RAM to keep your system up to date. Laptops, including those with the RTX 3070 Mobile, have limited upgrade options.


In terms of future-proofing, the RTX 2080 desktop may have a longer lifespan due to its higher performance capabilities. However, technology evolves rapidly, and both options will eventually become outdated.

Software and Driver Support

Both NVIDIA GPUs benefit from regular driver updates, ensuring compatibility with the latest software and games. The experience is quite similar in this regard.

User Experience and Versatility

The choice between the RTX 3070 Mobile and RTX 2080 desktop ultimately comes down to your specific needs and preferences. If portability is crucial, the RTX 3070 Mobile is a strong contender. However, if raw power and gaming performance are your priorities, the RTX 2080 desktop shines.
