920M for After Effects and Flash

[AfterLife6]

Good afternoon
Is an GT920M and 4GB RAM enough for low-medium work at 720p (rarely at 1080p) at after effects, flash and premiere?
I have two choices for this software:
i5 4210U - GT920M - 4GB RAM
I5 5200U - GT840M - 8GB RAM

The second one is 80€ more. Is it worth it, whould I notice the improvement in the performance?
Thanks

The 920m is based on the older Kepler architecture. The 840m is only clocked a little higher, but is based on the newer Maxwell architecture. So despite its model number seeming to be older, the 840m is actually the newer GPU. Its benchmarks seem to be about 30%-40% higher than the 920m.

Unfortunately I don't use After Effects or Flash so I can't say how important this difference is. Maybe the above links will help someone who does know.

There's not much difference between the CPU performance, since they both turbo boost to nearly the same speed. The big difference will be the i5-5200U should use less power since it's based on a 14nm process vs 22nm for the i5-4210U. (The architecture is the same for both CPUs.)

4GB vs 8GB is a pretty big deal if the memory is soldered and can't be upgraded. In that case I would definitely say the latter system with 8GB and 840m is worth it. But if you can upgrade the memory on your own, a 8GB memory module is only a bit more than 30 Euros. So you may be better off getting the first system and upgrading the RAM yourself.

the more expensive option should be quite a bit faster in After Effects work simply due to having twice as much RAM on top of a faster CPU (minor improvement) and GPU. the additional 80€ would be well spent in my opinion. (did a lot of After Effects work during college and found 4GB's to be inadequate, however for flash, its enough if your not multitasking much)

Thanks a lot!
