So the Microsoft Store has Surface Pro 6 8 GB 256 GB i5 Models on the floor. The CPU is a 1.6 GHz Quad Core but I had just tested Surface Pro 2017 models the week before from the SD Card reader. This was due to me purposely looking to get a Surface to then read .RAW or .ARW formats from my Digital Camera (Sony 5r and A7r3). As such the model I tested last week didn't have issues reading images, it immediately opened the .RAW files in most cases natively to then allow me to quickly filter the photos and then delete the bad ones via the Surface (my intended use). Last week I had also tested the Surface Go, which was noticeably slower due to the cheaper SD Card Reader in the Surface Go, it can't handle opening files as it takes 1-6 seconds to open them in the photo viewer (even .JPG files). However, the Surface Pro 2017 model I tested last week didn't have any issues reading files directly off of the SD Card. The Downside from my test today with the Surface Pro 6 was that reading the exact same files I had from my SD Card from last week were opening in about 1-5 seconds which is closer to the Surface Go's horrible performance. Was the SD Card switched out with a cheaper model or the CPUs are just throttled more to where burst reading files like this may be an issue? Or would the removal of the Iris graphics in the Surface Pro 6 line then ultimately greatly decrease the graphical capabilities and thus make it less ideal for reading images, digital editing and the such as I had intended? I was all set to pre0rder a Surface Pro 6 but after this, I think I'll have to wait until formal reviews on benchmarks, stress tests as well as seeing if they cheapened out on the SD Card reader or if the lack of graphics is a bigger deterrent for photo editing performance. If anyone knows at this point it would be greatly appreciated.
