I have been looking for more laptops with Thunderbolt 3 connection attaching directly to the CPU. So far the Thunderbolt 3 15″ MacBook Pro is the only such host. I have good news. The Alienware 15 R3 is configured the same way with a x4 PCIe 3.0 over Thunderbolt 3 connection to CPU.

Most people who buy one of these gaming laptops will probably not consider an eGPU. They have valid reasons. There are downsides for having such a powerful GPU inside the laptop though. First of all, Geforce Experience caps the GTX 1070 at 30FPS by default when on battery. When this option is turned off, the fans on this AW15R3 are very loud during heavy graphics use. 

The fans run at much lower speed when the eGPU takes over. This of course comes with performance loss. I ran Unigine benchmarks with the dGPU powering the internal display and the eGPU powering the external display. I received the AORUS 1080 Gaming Box this morning so I added some quick benchmarks on this table too. Here are the numbers.

An additional great review. Thank you. Great finding a non-Mac TB3-CPU host too.  This will be a good system to benchmark the upcoming GTX1080 Aorus Gaming Box. Since that GPU is 20-25% faster than a GTX1070, we may see it outbench the GTX1070 dGPU

@Nando4, I re-ran the AIDA64 tests and updated the original post. I received the AORUS 1080 Gaming Box today and did some quick benchmarks on it as well. First impression is that the 1080 eGPU indeed can beat 1070 dGPU.

Am amazed that the Alienware 15 R3’s GTX1070 dGPU outperforms the GTX1070 eGPU in raw computing numbers. Nvidia really did step up in their Pascal series to see mobile chips match their desktop equivalents in performance.

We see too the GTX1080 eGPU now does show the expected 20-30% improvements in raw computational and synthetic benchmarks.  Given the losses across TB3, does that now see the GTX1080 TB3 eGPU match or outperform the GTX1070 dGPU in some games?

I’m running game benchmarks and the GTX 1080 eGPU barely edges out the GTX 1070 dGPU at 1080p. At higher resolutions, my guess is the GTX 1080 eGPU will enjoy a wider disparity.

Usually in this cases there is a cpu bottleneck at 1080p and a gpu bottleneck at 1440p/4k resolution.

You need to assay the performances gain based on the resolution scaling when reviewing powerful gpu like the 1070/1080 and a locked cpu.

I’m not sure you can translate the performances gain differences between the 1070/1080 like you could do on a desktop.

Since even with a good 4x pci-e, it is not fully comparable with a desktop/laptop grade 16x wide, especially on minimum framerates and general frametime.

Can you do some tests for Ultra Wide Monitors at 3440×1440. That will be very interesting to see how the Gaming Box copes with that.

I will be running tests with a 4K monitor at 1440p and 4k resolutions. I don’t have an ultrawide at 3440 x 1440.

Hello everyone . As the new aorus box approach , so is the one of the GTX 1080mini from gigabyte . My aorus box 1070 is working fine but i can’t help wondering while reading these first reviews : is the enclosure exactly the same , and then is it easily feasible to swap from the 1070 to the 1080 mini ? Thanks for your answers .

I’m interested in that as well.

 

Also would like to know if  issue with half bandwidth has been addressed. 

 

Any thoughts, itsage?

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.

How much of a performance hit will this 1080 gaming box take running into a 2017 iMac 27″ i7/580 on the internal display at 1440p and 4k resolutions? Thanks

@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?

Thanks theitsage.

the 1080 mini is on its way. Will keep posted about the replacement process if it’s useful .

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.
