Nokia x100 vs samsung a13

I recently purchased a new eGPU that uses a newer JHL7440 controller compared with my previous eGPU which uses two controllers (a JHL6540 and a second JHL6240). I observed a surprising result where the lows were much better on the new eGPU compared with the old one. Both eGPUs were tested with the same 4070Ti graphics card and Samsung Book3 Pro 360 with a i7-1360p laptop.

The older dual controller eGPU performed better in synthetic benchmarks like Timespy.

However, in actual games, the dual controller eGPU demonstrated substantially lower CPU-95%-lows. In Horizon Zero Dawn, the JHL7440 based eGPU performed 37% better (48 fps vs. 35 fps). In the Shadow of the Tomb Raider, the new eGPU performed 60% better on the 95% lows (78 fps vs 50 fps) compared with the dual controller solution. This was the difference between playable with G-Sync and a unplayable stuttery mess.

This was an unexpected result so a bit of further research seems to suggest a potential cause for this issue. In the eGPU.io review of the Razer Core-X-Chroma they report the following:

We have learned single-Thunderbolt 3 controller enclosures can experience mouse/keyboard lag issues during heavy load. The remedy is to limit device-to-host bandwidth through Thunderbolt 3 enclosure firmware. This is not an acceptable workaround because the already-limited bandwidth (22Gbps) of the Thunderbolt 3 connection is reduced further. Fortunately there’s another solution. Razer was the first to implement a hardware fix for mouse/keyboard lag by adding a second Thunderbolt 3 controller to the main board of the Razer Core V2. They did the same with this Core X Chroma.

Basically, high end eGPUs of the earlier generation use a two controller solution to achieve 40Gbps bandwidth while still avoiding lag issues. However, my speculation is that this split setup causes the same type of problems as Crossfire or SLI. Having two controllers results in better synthetic results but when in actual gaming this results in stutter. Reviews have pointed out that while these dual controller setups are advertised as having a dedicated controllers for the GPU part and I/O expansion ports this is misleading because both controllers are daisy chained and share at most 4 PCIe lanes via a single cable (see https://egpu.io/razer-core-v2-review-think-inside-box/). I suspect that problems with this sharing of bandwidth and switching between the two daisy chained controllers can cause issues when using a more demanding 4070Ti card that I didn't experience using a 3060 or 3060Ti for example.
Conclusion: Older eGPUs based on single JHL6000 series controllers don't have enough bandwidth resulting in occasional mouse freezing issues (according to Razer). Higher end dual controller designs (like the Mantiz Saturn Pro or Razer Chroma X) tried to fix this by using adding an extra controller. When using newemore powerful graphics cards (4070Ti and 4080), however, I observed microstuttering on a dual controller system that wasn't observed when a newer single JHL7000 series controller is used.
Note: Thanks to u/glamdivitionen and u/esuil for pointing out that the JHL7440 controller is TB3. For some reason, I thought I read that it was TB4 and that the performance difference was simply due to increased bandwidth. These results suggest to me that further performance increases may be observed when TB4 compatible eGPU's come on the market.

I'm haven't watched competitive in a while so idk

I just wanted to share this, nearly spent £30 on a monthly pass before remembering they usually do it every year.
Would probably also ask the Mods to add this information on the pinned "Where to watch" thread.
