2017 15" Alienware 15 R3 (GTX1070) [7th,4C,H] + GTX 1070 @ 32Gbps-TB3 (AORUS Gaming Box) + Win10 [itsage] // boot off external SSD
My guess is that the firmware apply to the enclosure , not the card itself . So probably if the H2d update is done, replacing the card shouldn't have any effect on the bandwith . But this just a guess. What i found interesting is to gain 30% of performance in order to have an even partial compensation of the loss due to my 2lanes TB3 and to get close to a 1070 dGPU ...
Hi @papoose02 and @dream3, the AORUS Gaming Box enclosures are the same for both the 1080 and 1070. The only difference is the GPU. I took them apart and captured a couple pictures. The cooling fan on the GTX 1080 mini ITX is so massive that there's no room for a shroud. This fan is 130mm vs. the 90mm fan in the GTX 1070 mini ITX.
The firmware in the AORUS 1080 Gaming Box does not have H2D issue. It's running at 2,6XX MB/s Device to Host and 2,2XX MB/s Host to Device.
@Ty, I don't have an iMac to test but the performance hit will be significant. This is due to the iMac firmware disabling the integrated GPU. Without an active iGPU, you have to rely on a ghost-display adapter workaround.
Any (subjective) comments on the fan noise from that 1080 beastie?
About mid 40s dB during my testings. The majority of fan noise comes from the side where the two 40mm fans are. The GPU itself is rather quiet with the huge 130mm fan. The discrete GTX 1070 inside the Alienware 15 R3 screams in a bad way. When I ran dGPU benchmarks the noise exceeded 70 dB and temperature was higher than 60˚C. These were measured at the exhaust vents at the rear of the laptop. AW15R3 runs much cooler and quieter with the eGPU.
