Sorry but nothing you mentioned above will do the job.
Premiere has always been smooth and has never lagged once. Oh and I only have one video track if that makes a difference.
So any laptop i3 processor won't make it? What about an AMD A6 or A8? Those are much closer in terms of CPU/GPU balance.
Read the link I gave you; It is all spelled out there.
- CPU: at least a quad core i7 processor, preferably with hyper-threading. The faster the better.
- GPU: at least a nVidia GTX 660M or better with 1+ GB DDR5 memory.
- Disks: at least 2 internal 7200 RPM disks or a SSD plus a 7200 RPM disk.
- Connections: minimum is eSATA plus USB3 ports and Thunderbolt 2.0 is desirable.
- Monitor: at least 1920 x 1080 resolution and 15.4" screen size or bigger.
- Memory: bare minimum is 8 GB but workable is only 16 or 32 GB.
If you select a laptop with these qualifications, you can do some 'light editing' for most formats without too much jerkiness or choppy behavior, but it will still be much slower than a desktop.
The biggest drawback of a laptop is the limited number of disks, the need to use a wall-outlet and the premium price. It is a compromise.
AMD CPU's are not suitable for editing.
To see how good your desktop is, go to PPBM Benchmark, register and run the benchmark.
Oh my bad I thought that link was from Adobe themselves and so I automatically assumed they were "recommended system requirements".
the amd mobile cpu's would top out around the same speed as an intel i3 desktop speed, about half the speed of your i5 desktop. not recommended.
the average intel mobile i7 4-core cpu is around the same speed as your i5 desktop or amd 8-core cpu's. these are generally not recommended here, seen as too slow. however a few people have reported using these "too slow" cpu's in desktops and laptops with good results. the i7-47xxhq laptops with nvidia 845m or 950m, should be usable and may be lower in price as they are being replaced with next gen models. this would be similar spec's as cc_merchant points out.
the "amd not suitable for editing" recommendation may change when amd releases zen, but may also depend on adobe fixing large core count performance problems with their software.
