Hi,
I build a little bit more than i expected and push it there all in this thread.
I post it now, but i finished it 4-5 months ago.
I hope it is useful for anybody.
My old comfortable tableless working space(at now my 2nd but without eGPU)
System specs:
Model: Lenovo Thinkpad T14 (Gen 1)
CPU: Intel Core i5-10310U(4C/8T)
RAM 24 GB (16GB onboard + 8GB DIMM) DDR4
SSD: 1TB SK Hynix Gold P31 + Bitlocker
no dGPU
Windows 11 Pro 22H2
(and compare it with Lenovo Thinkpad E15 G4, i5-1245U)
eGPU hardware
eGPU: Razer Core X (bought it as used much cheaper, but cable was missing)
dGPU: MSI Radeon RX 6750 XT MECH 2X 12GB
(and compare it with KFA2 GeForce RTX4070 EX 12GB, KFA2 GeForce RTX 4060 Ti 8GB EX & ex. MSI Radeon RX 7600 MECH 2X 8GB)
Other:
0,8 meter Apple Thunderbolt 3 cable (40GB/s)
Internal Display only, no external Display
iGPU always on
-----------------------------------------------------------
Installation steps:
Not much.
Connected TB3 cable to TB3 port before press power on. GPU(or something unknown) are appear in Device-Manager.
1. Windows maybe install automatically drivers
- i have not check it, and not bann this, i dont care
2. Install AMD Adrenalin Driver
- Need driver with manual model select on the AMD-website. Auto-detect driver failed at first try.
3. Install newest iGPU driver from intel website.
- But Maybe install newest driver from OEM (Lenovo), when issues cant be solved.
done

usually Benchmarks:

3DMark Fire Strike & Time Spy

As i write a story....
-----------------------------------------------------------
...my english is not the yellow of the egg
-----------------------------------------------------------
At this time, i bought a eGPU for one game, Red Dead Redemption 2. For other games i used GeForceNOW, while at now, RDR2 ist not available.
Meantime is GFN sometimes unusable and i focussed me more for eGPUs now. A good alternative is Amazon Luna, but this service didnt support many Games. That is the reason, while i post this experience now.
My first steps was with a RTX4070 from KFA2. In tech sheets <1cm to long for Core X but it works fine.
In RDR2 i became ~15FPS ingame and ~30FPS in menu with this card at avg. 50% usage, and i was very sad, while its useless when i bought a 600€ Graphic Card for ultimatie 15 FPS ingame. Other users with TB3 and 4 lanes became the double FPS-Power.
I know: Newer Notebook perform better, but i use the Thinkpad origin for work in field service with thigh- and car-office and only with Excel, PDF, Word. At this time it was an unreally option for me. I bought the T14 before i think about an eGPU.
Any day, idea come in my mind, maybe AMD perform better... also i buy a suitable RX. Some Youtube fps-compare-Videos later, i decided me for an RX 6750 XT with good Price-Performance-Realtion at this time.
Result: With 400 €uro RX6750 XT i have out-of-the-box more FPS as with the RTX 4070 for 600 €UR.
Any problems?
1.
iGPU deactivate = system will be unstable after this.
2.
In RDR2 Graphics Settings Vsync must be off. When Vsync on = 1 FPS(& 0-1% GPU Usage) bug come by changing one graphic setting or when use integrated benchmark.
I found this Fix here: https://www.reddit.com/r/PCRedDead/comments/e8rpv5/performance_drop_to_1fps_and_1gpu_usage/
I have many time wasted with other Fixes there not help to solve this problem.
(DX 12 vs. Vulkan, DDU and clean driver install, Windows Graphic settings, Tdrdelay, ULPS off, etc...)
3.
With RX maybe change Output Adapter from 0 to 1 or 1 to 0 in RDR-Settings. After change between Vulkan and DX12, iGPU will start the game at first and Vsync and output adapter must be edit.
Courios is:
a) when graphic settings on middle-Level, CPU will be bottleneck while CPU is used 99% and GPU average 50%. With ultra settings, CPU will be 50-80% and GPU 99%
b) i have more FPS with Vulkan as with DX12 and on DX12 the Game shine a litte bit unstable
c) i havent lower issues with RTX. When RTX was connected, only dGPU will be used and i cant change Output-Adapter in RDR graphic settings
Other graphic cards and Notebooks:
After this, i would be do a very small experiment. I will test RTX 4060 Ti and RX7600 with my usecase-setup.
While i cant use the full bandwith, i was interested, how much better or badder perform this cards with my setup or usually with lower bandwith.
By time, i bought a Lenovo Thinkpad E15 G4, described as a E14 G4, but okay - i bought it used and cheap.
I havent much time for full benchmarks series. I forgot backup my graphic settings in RDR2 with E15, 4070 and 4060 Ti. My experience is maybe not compareable.
I have test the Razer Core X with:
1.
RTX 4060 Ti and RX 6750 XT on Lenovo Thinkpad E15 G4 (i5-1235U, 8GB RAM, 256GB SSD, TB4)
- i used the iGPU software from Lenovo, while i had issues with newest Intel driver and Display driver show a future date in version...wtf
- 8GB RAM and 256GB SSD are very tight, sometimes RDR would be crashed while not enough RAM.
- Maybe better performance with more RAM and bigger SSD
2.
RTX 4070(600 €UR), RTX 4060 Ti(400 €UR), RX 6750 XT(400 €UR) and RX 7600(270 €UR) with Lenovo Thinkpad T14 (G1)
I used at first 4070, then 2nd try with 4060 Ti and RX 6750 XT, and at last 6750 XT and RX 7600.
Between RTX and RX i used DDU before switch.
But, i didn't have all the cards at the same time
results?
Out of the box, any RTX performs very badly on the T14. RX performs always better.
With E15 Gen 4, RTX performs better and the difference between 4060 Ti and RX 6750 XT will be smaller, but RX is faster.
On T14 Gen 1 RX 7600 performs a litte bit lower as RX 6750 XT, but better than RTX graphics.
With similary graphic settings, RX 7600 is near RX 6750 XT on the T14.
T14 Gen 1 (G1) RDR-Benchmarks with similar graphic settings:
1. RTX 4060 Ti @ T14 Gen 1, DLSS on, DX12
2. RTX 4060 Ti @ T14 Gen 1, DLSS on, Vulkan
3. RX 6750 XT @ T14 Gen 1, FSR off, normal graphic settings, Vulkan
4. RX 7600 @ T14 Gen 1, FSR off, normal graphic settings, Vulkan
5. RX 6750 XT @ T14 Gen 1, FSR off, stronger graphic settings, Vulkan
6. RX 7600 @ T14 Gen 1, FSR off, stronger graphic settings, Vulkan
E15 G4 RDR-Benchmarks with unknown settings:
1. RTX 4060 Ti @ E15 G4, DLSS on, Vulkan
2. RTX 4060 Ti @ E15 G4, DLSS & FSR off, Vulkan
3. RTX 4060 Ti @ E15 G4, DLSS on, DX12
4. RTX 4060 Ti @ E15 G4, FSR on, Vulkan
5. RX 6750XT @ E15 G4, FSR on, Vulkan
by time, i sold the T14 G1 and E15 G4 and bought a newer T14 G3.
thx for reading.
