Are external GPUs (eGPUs) still a viable option in 2025? With the surge in laptop GPU performance and the rise of dedicated NPUs for AI workloads, understanding the practicality of eGPU setups is more crucial than ever. For gamers and creative professionals, eGPUs represent a compelling way to boost performance in lightweight ultrabooks, but the landscape is evolving.
As a professional content strategist focused on tech, I’ve observed the growing nuances in eGPU solutions and their impacts on users. Let’s dive into the current state of eGPUs and see if they still hold value for your specific needs.
1. What Can You Expect from Today’s eGPUs?
Modern eGPUs like Razer’s Core X V2 showcase the advancements in external GPU technology. This device leverages the new Thunderbolt 5 interface, boosting bandwidth to a staggering 80Gbps or up to 120Gbps in specific modes, offering desktop-class performance over a cable more effectively. However, not all previous limitations have been resolved. Users must still provide their own power supplies with the new models, and compatibility concerns with Apple Silicon Macs persist.
2. Performance Gains and Limitations
Even with faster Thunderbolt connections, eGPUs don’t quite match the speed of internal GPUs. For instance, a detailed analysis by PC Gamer compared setups using an RTX 4070 Ti and an RTX 4090 under various configurations. They found that Thunderbolt setups were approximately 25% slower compared to OCuLink connections, with evident frame stutter issues. If you’re considering an eGPU to enhance your gaming experience, it is advisable to pair them with upper mid-range GPUs. These are less likely to encounter bandwidth limitations and can still deliver commendable performance.
3. Is Cost a Major Factor with eGPUs?
Investing in eGPUs requires considerable financial commitment. The Razer Core X V2 itself costs around $350, not including a GPU or power supply. Considering comparable gaming laptops, you might find it more practical to buy a laptop that already includes a powerful graphics card. Moreover, many people are uncertain whether the cost justifies the performance trade-off, especially when cloud gaming services are on the rise.
4. Portability and Usability Concerns
Portability is another critical issue with eGPU setups. They’re not designed to be easily transported; unlike high-end gaming laptops, which integrate GPUs internally, eGPUs require space and additional power connections, making them less suitable for those frequently on the move.
5. Will eGPUs Become Obsolete?
With advancements in laptop technology, integrated GPUs are now more powerful than ever. This raises the question: is it worth investing in an eGPU? For many consumers, acquiring a new gaming laptop may be more straightforward than configuring an eGPU setup.
So, if you’re a gamer or creator asking yourself: “Are eGPUs still worth it?” the answer may vary. For gamers experiencing speeds of up to 120Gbps, there remain compelling benefits. Yet, for everyday users looking for compatibility and ease, alternatives like cloud gaming could provide a fitting solution.
What performance can I achieve with an eGPU compared to my laptop’s internal GPU? You can typically expect around 70-80% of desktop performance from an eGPU combination, depending on the GPU and the connection type. High-end GPUs might struggle due to bandwidth limitations.
Can I use an eGPU with my Mac? Currently, macOS devices with Apple Silicon do not support external GPUs, limiting compatibility and use to Windows systems with Thunderbolt or USB4 ports.
Are cloud gaming services an alternative to eGPUs? Yes, services like Nvidia GeForce Now and Xbox Cloud Gaming allow gamers to stream AAA titles without needing powerful local hardware. It’s an affordable alternative that requires a reliable internet connection.
In conclusion, as we weigh the advantages and disadvantages of external GPUs, it’s evident that they still have a niche appeal, particularly for specific use cases. If you own an older laptop and have existing GPU hardware, an eGPU can indeed elevate your experience. Yet, for most users looking for a straightforward solution, a new gaming laptop or cloud-based options may be the most efficient pathway to enhanced graphics performance.
