Hardware accelerated UI and AHB bus overclocking

[Guest adam5533]

I just changed my rom today to jellyfish rls6 and wondered what the addons were for. Can anybody tell me what it actually is used for and is it beneficial?

thanks

[Guest vareBlade]

And couldnt you ask in the jellyfish rls6's topic?

[Guest adam5533]

Didnt think it was just for jellyfish. Ive seen different roms that use it and at different speeds.

So, have you used the search to find out yourself? Because there is a lot of information that people should first try to find themselves.

[Guest adam5533]

Nevermind.

Actually it is used for draining battery faster :D

hw acceleration helps some 3D games at the expense of shorter battery.

AHB bus overclocking theoretically improves the phone's performance by speeding up the communication between the device's different parts, but your mileage might vary.

[Guest adam5533]

Thanks thats what i wanted to know, I had searched but could only find info about peopl saying they had done this but not actually saying what it is for and how it could affeft lifespan, Just the same as on the ps3 or psp. Thanks

That AHB bus overclocked drains more battery too?

[Guest Pierreism]

Practically anything that speeds up operations in your phone consumes more battery, but it shouldn't be by much if it's not doing anything intensive.

Ahhh, I remember when you could choose to play PC games with software rendering instead of OpenGL. /OT /nostalgia

Well, it doesn't seem so obvious - rendering requires power even it it is done by the CPU instead of GPU.

Of course. You are running things at higher speeds than default.

[Guest KenBW2]

Of course. You are running things at higher speeds than default.

But for example a GPU is better optimised for what it does than the all-purpose CPU. So just because you're getting more horse power out of the GPU doesn't mean it's using more battery to do it. Note I'm not saying what happens in reality - just that it's theoretically possible to get better performance without affecting battery life.

[Guest Swiftes]

Think of them has overclocking your HTT/FSB/QPI etc on PC's, you're increasing the bus speed so the cpu and memory can communicate faster and use less clock cycles, at the expense of poorer power consumption.

Anyone know what AHB actually stands for? I've never seen it written out, and like adam5533 I've had no luck searching.

I'm really not buying into this idea that HW acceleration is a battery drain. Dedicated HW can perform a task much more efficiently than SW running on a general purpose processor. I'm a professional electronics engineer (not in the cellphone business though) and in my field we would always choose to offload SW tasks to dedicated HW if we need low power, all other things being equal.

Just trying to think what is it about cellphones that could make them different in this respect.

With the availalbe roms on the ZTE Blade, enabling hardware acceleration in build.prop increases battery drain, try it and see. ZTE probably have it disabled by default in their roms for a reason, it could be unfinished, inefficient code that adds unecessary computation.

I suppose it comes down to how efficient the CPU and GPU are. Perhaps at this early stage power management is not at it's very best on the GPU side of things. Could be a number of reasons, even bad drivers.

[Guest Cardyology]

Is it ok to use the AHB over clocking add-on with setCPU?

[Guest AceOfSpades]

I just installed the hardware acceleration and it seems to make menus more laggy thatn with it off, havn't tested any games with it though. On japjelly latest

[Guest snowbord]

So does hardware accelaration decrease battery or not? It does sound counter intuitive that it may.

I'm entering late on this topic but:

Against facts we can't have arguments!

I have now a ZTE Blade/Libra with GEN2 and Swedish Spring RLS5.

It comes with an App wich is "Extra Settings". This App can enable/disable "Hardware Accelerated UI".

Without this activated I have +/-3 days battery. With it ON I have +/-1 day.

This should answer anyone's question.

Advantages or What does it do?

As far as I can tell: it enables, or more than that, it powers ON a GPU (like someone said).

Why do I say that?

Because, running "Angry Birds Rio" without it the game runs with hiccups (freezes for a few miliseconds so many times) and finnaly crashes!

With the "Hardware Accelerated UI" ON the game runs beautiful! No freezes, no lags , nothing bad. Really smooth.

The problem?

I think the GPU is always ON once enabled.

Windows has a process called "IdleCPU". Android should have one too.

There should be a process that powered ON the GPU.... ONLY when needed.

Hope this clarifies the subject.

Thank you.

You must be new to the internet! :D

"SSParts.apk" wich come with SS RLS5.

You're right on your remark, 'though I'm not new.... it was silly! I admit. :D

In fact, since I posted this I remembered that I haven't calibrated my battery..... I'll come back later.
