No big issue till now, very happy to made a self soldered HMI cable that allow me to work in GEN2 ExpressCard mode (GPU-z tell me PCIe x 16 2.0 @ 1x 2.0 during 3dMark and Fraps benchmark)

 

  • Performance
    • 3Dmark 06
      • 10143 (SM2.0 4079, HDR/SM3.0 5030, CPU 2507)
    • 3Dmark (steam DEMO version)
      • Firestrike 3886 (24.81 FPS Gt1, 20.92 Gt2, 8.7 FPS Physx, 7.9 FPS Combined)
      • Icestorm 22488 (98 FPS Gt1, 98 FPS Gt2, 71 FPS Physx)

 

Unfortunately i have bad performance on benchmark (except Firestrike) if i made a comparison also on this Forum with other systems. I don't know if Opt1.2 use pci-e compression through HD3000 or is just a CPU limit that i reach. All test are made on internal lcd only (that is my focus now).

 

Does anyone idea why? Any suggestion?

 

Follow system screenshots and pics

Yeah, your processor is the weakest point in the system. The best performance for egpu provides i7 Quad Core. You should think about CPU upgrade.

You posted benchmark results - you tested on external screen (attached to egpu) or on internal screen of your laptop?

I am interessed only on internal display. But if i use external one should i have maximum performance (so limitation is sure CPU related?). Can i use this data to see if HD3000 compression is disabled or not?
