WM8650 Uberoid Firmware Upgrade

 

In the Chinese tablet market find a variety of CPUs, more presisamente SOC (System on a Chip), the vast majority of these being of ARM architecture. These SOC incorporate parts as CPU, GPU, DSP, L1 and L2 caches in a single package. This guide is not 100% accurate and is based on my personal experience, current as of October 5, 2012

By choosing the cpu for your tablet or smartphone Chinese should carefully several aspects:

Cpu type: Just as you find excellent tablets cortex A9 CPU 2 cores as rk3066 also find garbage as those based on the WM8650 (ARM9), a better cpu will allow you to run games more complex, more fluid web browsing, better multitasking, if dual core is going to look at multitasking, if the cpu is common you can find alternative roms, web support, mods etcs. Look not only the speed but also the architecture MHZ as such is several times faster CPU at 600Mhz cortexA9 a 900MHZ ARM9

 
Type GPU: CPU is responsible for processing the standard code of games and programs, but for graphics tasks using the GPU (graphics card equivalent to a pc), GPUs are very good as the series MALI (400-400MP4 ), Power VR SGX531 Imagination-535-540, Adreno 200-220-320, regular as Vivante GC800 and GC400 Vivante terrible as-GC200. 3d Good games are usually optimized for certain types of GPUs, GPUs run these games uncommon as Vivante GC800 can produce unexpected results and strange colors, lack of textures, graphics errors, even some games do not run in the GPU. Search google details like processing power of polygons, OpenGL support, bandwidth, etc.

DSP: Also called VPU, this is responsible for the reproduction of video and audio hardware accelerated, improved DSP will allow you to play videos higher quality, also when using hardware acceleration will free the CPU of that work by increasing the battery life. There are very good as DSPs using Allwinner A10 processor that allows you to play up to 2 simultaneous videos in 1080p or terrible as the WM8650 processor to only play videos until resolution 640x480p

Caches L1 and L2 are small RAM located within the processor, are very fast but also expensive, so we can only include a few kilobytes in processor. This memory is used to store data that the CPU uses quite frequently to avoid having to access the main RAM is slower. Poor implementation of the cache can generate low yield as happened in AML8726 Amlogic cpu-M.

OS Quality: It is no use a fast CPU if combined with a poor implementation of Android. The android tablets using Chinese standard is not 100%, here companies change modules, improve some things, deleting others and work according to their programmers affects android experience. In my experience I have seen that Rockchip has always provided fast and stable versions of android, like Via, others like Infotmic were terrible.
CPUs TABLETS CHINESE IN DETAIL

WM8605-8650: cpus are produced by Taiwanese company Via, more precisely by its subsidiary WonderMedia Technologies, using ARM9 architecture, a single core, its speed does not exceed 600 MHZ, not integrated GPU (very bad for games) and the DSP terrible (video up to 480p and only certain formats), LCDs supports resolution up to 800 × 600 px, resistive touch screen supports only, supports flash mediocre player, high energy consumption and heating. As advantages of its low price, ease of installation, stable android firmware update is easy.

ATM7019: Made by the Chinese company ations semiconductors based on MIPS32 architecture, being ARM MIPS architecture and will not be compatible with the latest and greatest android games, I could not find info about that gpu uses. Its advantages lie in its low price and low power consumption. Be careful as many good cheap tablet vendors will use this cpu and going to be slow and will not be compatible with good games.

VC882: cpus are produced by Taiwanese company Vimicro, use Cortex A8 architecture, a single core, its speed does not exceed 1.2GHz, integrates a small GPU (regular games), DSP Regular (regular video playback), supports LCDs resolution up to 1024 × 800 px, supports resistive and capacitive touch screens, supports flash player. It is a somewhat unknown cpu, its software is not very stable but it is quite economical, its performance is acceptable.

AML8726-M: cpus are produced by Chinese-American company Amlogic, use Cortex A9 architecture, a single core, its speed does not exceed 800 MHz, a good integrated GPU (Mali 400 but at half speed in MHz than the competition) , well DSP (good video playback), supports resolution LCDs up to 1024 × 800 px, supports capacitive touch screens, supports flash player, supports HDMI. CPU performance is acceptable, although performance Cortex A9 has a Cortex A8, this I think is because it uses an ancient process (65nm) which makes the cpu can not exceed 800 MHz and the GPU should run low speed, L2 cache are low (also affects performance), plus the software is not very good.

A10-A13: cpus are produced by the Chinese company Allwiner, use Cortex A8 architecture, a single core, its speed is normally 1.0 GHZ 1.2 GHZ max tablets up to 1.5 GHZ small and large tablets, integrates a good GPU (Mali400 fast and compatible with many games), excellent DSP (simultaneous playback of 2 videos up to 1080p), LCDs supports resolution up to 1024 × 800 px, supports resistive and capacitive touch screens, good support of flash player. The A10 supports HDMI and is BGA package, the A13 does not support HDMI and is QFP package but is cheaper. Their software is very stable, low power consumption, good performance, very easy software update you.

NOTE: There is a high degree of confusion about the name of these cpus, but the brand name is really possess A10 Cortex A8 CPU, unlike what many published is 1 single core, plus the speed of the cpu in tablets small is almost always 1 GHZ and 1.2 GHZ very few actual times. When sellers the dual core is offered as allegedly relate because it contains cpu, gpu, vdp etc, but all cpus are 1 or 2 cores also include these components.
