Performance benchmarks for mobile parts are meaningless without power consumption data.

True. If this is around a 30 watt tdp, it would have amazing power consumption numbers (for reference, they were comparing it to a 1070 max q, which could have a max tdp of 115 watts).

[–] deegeese@sopuli.xyz 21 points 3 months ago (2 children)

Wikipedia lists the 780M as 35-65W so 30W sounds a little too optimistic.

[–] Addv4@lemmy.world 17 points 3 months ago

Even then, that is pretty impressive with a cpu and gpu together (sorry, haven't looked at the newer cpu tdps in a bit, was thinking older mobile chips).

I have an older 680m in my laptop and it performs pretty well with a combined package power of under 45 watts. Usually the last 10% comes at like 50% increased power consumption so that may be where the 35-65 watt range comes from, but the final performance shouldn't be too far off.

I always calculate performance /( TDP * price) when looking at new relevant PC parts, something most reviewers don't bother doing.

I can guarantee you that with a Radeon running at full speed, it isn't going to be long. But seeing a browser time benchmark would be nice.
