LG eight nuclear run of exposure! LG Odin became the first PowerVR6 core

Recently a large number of mobile phones have released eight-core, LG is also eager for it. LG has been planned prior to produce their own ARM-based processor, code-named Odin now testing machine has been uploaded in the database security Bunny, Odin 28nm HK-MG-based manufacturing process from TSMC (TSMC) foundry, based on the ARM architecture There are eight cores. Rumors Odin and Samsung Exynos 5 Octa same as that using ARM's big.LITTLE / Cortex A15 architecture, its interior were made up of four eight-core Cortex A15 architecture core and four Cortex A7 core component architecture. From an engineering machine test scores, Odin score 27000 and Exynos 5410 was essentially flat, it is likely also the dual quad-core.

      There are rumors before Odin will be used in the LG G2 (D802) on, but to get the test machine and no significant data confirms this rumor, now more certain is that Odin has eight physical cores, running on a 2G RAM +36 GB on (engineering machine detects errors) of equipment, test with a resolution of 1776x1080, ie the resolution of this equipment is 1920x1080 (virtual key took part).

      CPU is clocked at 100MHz ~ 1008MHz now , here are two guesses:

1, Odin does not rely on high frequency to improve performance, micro-architecture should have a good competitiveness, while it can determine the lower limit frequency of 100MHz designers should focus on increasing the low-power control.

2, frequency testing machine still debugging, if higher, the results will rise significantly.

      Also Odin integrated powerVR ROGUE HOOD, because the reason the test machine, it is unclear the specific code. PowerVR ROGUE HOOD fact Imagination Technologies next generation GPU core, PowerVR 6 kernel name is called Rogue, this series seems very new, in fact, as early as in January 2012 it was released, but has been in the test, and now finally To the market. Currently known series includes a PowerVR G6200/G6400, PowerVR G6230/G6430.

      As PowerVR 6 series of new features, the official propaganda will ever support DirectX 11, is also planned to provide support for next-generation OpenGL ES (codename Halti), as well as OpenCL and GPGPU's.

        Compare the accident is the first chip PowerVR 6 is actually used in the above LG Odin, rather than the other veteran Soc manufacturers. As for the reason, we can take a look at the detailed scores, although the 6000 pay would only works in test scores, has not been fully determined, but generally does not fluctuate more than 1000 points, Odin built Fengyun GPU performance and Adreon 330/Geforce ULP/Mali-T628 or worse compared to many. So now used on speculation that Odin is positioned lower PowerVR G6200 , so this result is plausible, after all, PowerVR SGX544MP4 performance should exceed this.

This table also shows a lot of performance issues:

1, the test scores, and we found a significant low 2D test scores, which should be driven imperfect result , so for Fengyun GPU scores have a lot of expectations.

2, CPU floating point performance, the whole point of significantly more than 800 Xiaolong, CPU operation is part of LG worth seeing on their own strength.

3, the virtual machine performance is low, yingzheng drive a larger problem.

       For more information about the PowerVR currently still small, only know "PowerVR G6200 and G6400 are four double clusters and cluster design architecture offers the best performance in the smallest possible area; PowerVR G6230 and G6430 will" go all out " , at the lowest possible power consumption to further maximize its performance "through additional area overhead.

      LG developed its own processor would never act is just for fun, it's the same as Samsung aims filled the whole industry chain, the core things hold in their hands, Odin issue now because the driver testing machine, resulting in virtual machines, 3D testing results as well as a lot of upside here bold guess it should be the ultimate performance with Xiaolong 800, Tegra4, Exynos 5420 equivalent, and part pure CPU computing power is so strong that These chips over the top is not a problem.
