Speed Tests Comparison
Comparing Thunderbolt 5 and Thunderbolt 4 speeds helps us understand their real-world performance. External GPUs rely heavily on fast data transfer. This comparison focuses on how each version handles GPU speeds under typical conditions. The tests measure throughput, latency, and stability during high-demand tasks. Results reveal how each Thunderbolt version impacts eGPU efficiency and user experience.
Test Methodology
We used the same external GPU model for all tests. The laptop had ports supporting both Thunderbolt 4 and Thunderbolt 5. Each test ran multiple times to ensure accuracy. Transfer speeds were recorded using benchmarking software. We measured data rates during gaming and graphic rendering sessions. The environment stayed consistent to avoid performance fluctuations. These steps created a fair and controlled comparison.
Thunderbolt 5 Results
Thunderbolt 5 showed a clear speed advantage over its predecessor. Average data transfer rates reached up to 80 Gbps. Latency dropped, allowing smoother frame rates during gaming. Stability remained high with no significant drops in speed. The interface handled large file transfers more efficiently. These improvements suggest Thunderbolt 5 better supports demanding external GPUs. Users experienced less lag and faster load times.
Thunderbolt 4 Results
Thunderbolt 4 delivered solid performance but lagged behind Thunderbolt 5. Data rates maxed out near 40 Gbps in tests. Latency was higher, which caused slight frame drops. File transfers took longer, especially with large data sets. Stability was generally good but less consistent under heavy loads. Thunderbolt 4 still works well for many eGPU setups. It provides reliable speeds but at half the bandwidth of Thunderbolt 5.
Gaming Performance Impact
Gaming with an external GPU depends heavily on data speed between the computer and the eGPU. Thunderbolt 5 offers higher bandwidth than Thunderbolt 4. This increase can affect how smoothly games run and load. Understanding the impact on gaming performance helps gamers choose the right setup for better play experience.
The connection speed affects how fast game textures, models, and effects load. Faster speeds reduce lag and stuttering during gameplay. Let’s explore how read and write speeds influence this and see real-world gaming tests.
Read Vs Write Speed Effects
Read speed is more critical than write speed for gaming. Games mostly read data from the eGPU to render frames. Thunderbolt 5’s higher read speed means faster delivery of graphics data to the computer.
Write speed mainly matters when saving game data or streaming gameplay. Thunderbolt 5 improves write speed, but this has less impact on real-time gaming.
Lower latency and better read speeds reduce frame drops and improve responsiveness. Thunderbolt 4 can handle many games well, but Thunderbolt 5 provides a smoother experience with high-demand titles.
Real-world Gaming Benchmarks
Tests show Thunderbolt 5 delivers up to 20% better frame rates in some games compared to Thunderbolt 4. High-resolution and VR games benefit the most from this boost.
Older or less demanding games see smaller differences. The speed gain helps mainly with games that load many assets quickly.
Benchmark results confirm that Thunderbolt 5 reduces stutter and load times. It supports higher refresh rates and better graphics quality without lag.
