Hi guys,
Is there any documentation on the power consumption of the Mali 400 MP2 during different ops. How does this compare with the Mali 470 ?
Just curious.
Regards,
Rajesh.
It is a fact that Mali 400 MP2 is one of the most popular GPU for their consumers and users that features almost 20% of devices. It is the world's first OpenGL ES 2.0 supporting multi-core GPU. It has also the capacity of supporting the powers for CPU & GPU separately. Moreover, the design for GPU 400 MP2 separates it from others because straightforward implementation and interface. More importantly, Mali 400 MP2 also gives a quality of graphics to users that not only help them during their daily operations but also help them in viewing logos of different programs quite clearly. Specially, logos that are being created by professional logo designers in Dubai for their prestigious international clients of different industries.
HI Anees,
Thanks, but I was hoping for some numbers in terms of mA at different loads. Ballpark figures.
Hi, There isn't any public power data available from Arm because (1) our partners will use different silicon implementations (process nodes, cell libraries, choice of top frequency, etc) and (2) on most platforms it can change dynamically due to frequency and voltage scaling. The combined effect of these two together can be large - even on a single process node I would expect to be able to create a 5x difference in energy consumption for an otherwise identical piece of content across implementations just by using different physical implementation choices and voltage levels.
As a horrible rule of thumb things which touch memory, such as texturing and vertex attribute access, are going to be more expensive in terms of energy consumption than simple arithmetic operations in a shader program.
Mali-470 is substantially more efficient at handling texture cache misses than the earlier Mali-400 and -450 products, so we expect something like 40% energy efficiency improvements for texture streaming content such as user-interface rendering.
HTH, Pete
Thanks Peter .. that helps a lot.
