RAM in computers vs phones

It prob depends on the game developer to make use of the phone in built GPU capability

EA made Need For Speed No Limits for the mobile and they use both OpenGL and Vulken API for the game and it does look stunning.

 

yes i agree to some point that ppl leave app running in the background without completely closing it.

 

Coming from my Samsung S4 to the current S7 Edge, I always have the habit of closing all my previous apps to clear the RAM being used. And also frequently clear my phone cache of any junk files.

 

With the current Android 7, true multi tasking is still not possible. Yes you can play your own music over the app that your are using.  

 

I still hate the fact I can't play my Youtube music play list while the screen is off.

My main browser for my phone is Firefox instead of Chrome. So my RAM usage isnt as bad

Prob the most RAM hungry app is prob Need For Speed No Limits

 

Vs the last gen consoles, the most glaring cutbacks (as far as visual effects) tends to be in the shadows. Very few mobile games make use of fully dynamic shadows, actually, though to be fair, it didn't look particularly good on the last gen consoles due to the low shadow resolution. I suspect a draw call bottleneck on mobiles, making dynamic shadows more expensive than they would otherwise.

 

Textures have been better than what the PS3/X360 could do for quite some time, undoubtedly due to the egregiously large quantities of RAM in modern devices. Even the textures in something as old as Epic Citadel tend to be of a higher resolution than what was seen in the aforementioned consoles.

 

Android 7 does allow for split screen multitasking, though the primary use I found is to get around YouTube's arbitrary (and idiotic) limitation against playing stuff in the background while browsing. Running Maps and the browser simultaneously also works well too.

most games use the phone RAM as VRAM as well so i will say recent phones with more RAM like the Razer Phone and DDR4 in particular will help boost the GPU performance because it will be able to load more textures onto RAM before displaying it on the screen.

While that is the case, I'm not sure memory bottlenecks are a problem in modern flagships. On some of the games I've played that suffer performance issues (this is a Snapdragon 821), changing the resolution makes no difference whatsoever. Though in the case of tiled rendering (where the gpu renders tiles to internal cache instead of memory), I don't think I can discount memory bottlenecks in the sense that the gpu can't pull texture and buffer data fast enough.

 

As shadows require a stencil, or z, buffer, which is probably stored in Main Memory, I suppose it is possible that it is an inordinately expensive effect on mobile devices vs just giving more work to the powerful shaders. Volume shadows wouldn't be much better either as overdraw is now a factor.

sounds like a case of a CPU bottleneck rather than a GPU or RAM bottleneck

 

i find it weird why Samsung still need two different CPUs for regions

 

Snapdragon in US/Canada and Samsung Exynos in Asia

the Snapdragon and a higher burst clockspeeds but the Exynos performs better in multi tasking and CPU workloads and Vulkan API leverages on the CPU treads to get more performance in games so far.

CDMA is still fairly popular in the US (Verizon, Sprint). This seems the most likely reason.

 

The Snapdragon 821 has a pretty monstrous gpu, but most games seem to be hamstrung by the CPU well before the GPU can get to work. For Qualcomm's part, the Adreno 530 gpu is probably vastly overkill for anything but benchmarks.

To answer anyone criticizing my pc/mobile specs, I have a laptop with 16 GB RAM, but then it obviously is not a budget laptop, I run solidworks and catia on it.

 

The reason for me to open this thread was actually a little different, I have a lumia 950xl (3 GB RAM) and a Motorola G4 plus (4 GB RAM) but I noticed that my Motorola works somewhat slow when compared to my lumia, that's why I started this thread.

If you want to play mobile games, 2 Gb is not enough.

You may be right, I haven't played games on my phone in awhile. The most demanding game I play is 8 Ball Pool. I used to play GTA 3 on my Xperia Tipo, but that was almost 3 years ago.

From my experience Android phones slow down over time. Some newer versions of apps use much more resources, but don't offer more feautures than older versions. For that reason I update apps only when they stop working or a new feature that I want/need is added.

I just tried that game. Another noted cutback that is relatively subtle seems to be in the poly counts. Wheels and the wheelwells are the giveaways here. Not necessarily knocking it, I definitely like the texture work. 

 

I didn't like this game much though, the races are far too short, and the fuel thing seems to be typical EA fashion (why I don't like Real Racing 3). Seems like it is meant to finish up the races before the device starts throttling.

So in other words, CPU bottleneck on a poorly-balanced SoC?

Probably, though draw calls always seemed to be an issue on mobile devices if browsing development forums is anything to go by. Not as though there's much faster in the Android realm on single thread performance anyway though, so I don't think it matters all that much.
