标题: PowerVR 6 将具备 20-100 倍 PowerVR 5 的性能

http://www.electronista.com/arti ... rvr.sgx600.details/

Imagination Technologies in a low-profile step has given out the very first details of its next-generation PowerVR mobile graphics. The 6 series, nicknamed Rogue, is expected to be an exponential speed boost; it should be at least 20 and as much as 100 times faster than the SGX500 series graphics it would replace, the chip designer said. Simultaneously, it won't use any more than one milliwatt of power, keeping it suitable for smartphones and tablets.

While the company hasn't outlined what the capabilities will be, ST-Ericsson has already given an estimate for what a production chip could do. Its future Nova A9600 will combine a 2.5GHz ARM Cortex-A15 with the PowerVR 6 to produce virtually desktop-level graphics; it should handle 350 million real-world polygons per second and five gigapixels per second, ST-Ericsson said. The speed up would lead to 1080p video at 120 frames per second, four times what's usually possible today, and "professional" quality 3D recording.

Imagination didn't say when mobile devices would start shipping with the new PowerVR hardware, but ST-Ericsson expected the A9600 to arrive as test samples sometime this year. The timing would imply mass production for other companies in or by 2012 and could lead to major PowerVR implementers, including Apple, getting major performance improvements in as little as a year.

In the interim, the company also hinted that its much nearer term PowerVR SGX543 and SGX544 would come sooner than expected. They should reach the first shipping products "within three months," it said.

好吧，估计只是理论，实际不可能有那么多，看太多了案例

我记得 6600 GT 的 pixel fillrate 也就是 4 Gpixels/s 的水平。

嗯，很好，WII2估计就用这个了

PowerVR在移动图形市场的地位还是非常强势的 NV以后可能授权给其它厂商吗？

最快的双通道lpddr2带宽也就4.3G/s，除了嵌入式显存以外，我看powerVR这牛皮要吹炸了

面对多个厂商，特别是NV的强力冲击，不得不搞宣传

这里还有一个情况，那就是 PowerVR 在填充率上都是宣传所谓的有效填充率，这样就有可能出现物理填充率为 1.25Gigapixels/s，这样也许可以得出 4 pixel pipelines @ 315MHz。

佩服。。。都21世纪第二个10年了，我想看看现在有几个游戏全程无效像素填充能占到70%。。。

st－ericsson官方提到是20倍性能提升，100的说法倒没提到。
就算是20倍性能提高也没有什么大惊小怪的吧，NV的TEGRA的路线图也是很夸张啊，从65nm时代的SGX530（5系最弱的一款）到28nm的新一代，这样的提升很正常

如果不信官方的说法也没办法

Changing the game: ST-Ericsson Unveils NovaThor™ Family of Smartphone Platforms Combining its Most Advanced Application Processors with the Latest Generation of Modems

February 15, 2011

Complete solutions bring unprecedented computing and graphics performance to smartphones and tablets, at lowest power consumption ......
The Nova A9600 will be the first platform announced to incorporate Imagination Technologies next generation of graphics processors, codenamed Rogue, which will set a new performance bar for GPUs at mobile power consumption levels. The Nova A9600 will bring more than a 20-fold improvement in graphics performance compared with the U8500 platform.

“POWERVR Series6, codenamed ‘Rogue’, moves the goalposts in terms of graphics performance and efficiency at low power consumption for next generation mobile.” said Hossein Yassaie, CEO of Imagination Technologies. “We are delighted to be working with ST-Ericsson on such a groundbreaking product.”
The Nova A9600 will also be able to play full HD video at 120 frames per second, supporting professional camcorder-quality recording in 3D, as well as high definition videoconferencing and tele-presence.

Notes to Editors
The Nova A9600, built in 28nm, will deliver groundbreaking multimedia and graphics performance, featuring a dual-core ARM Cortex- A15-based processor running up to up to 2.5 GHz breaking the 20k DMIPS barrier, and a POWERVR Rogue GPU that delivers in excess of 210 GFLOPS. The graphics performance of the A9600 will exceed 350 million ‘real’ polygons per second and more than 5 gigapixels per second visible fill rate (which given POWERVR’s deferred rendering architecture results in more than 13 gigapixels per second effective fill rate). Thanks to Rogue Nova will support all existing APIs such as OpenGL, OpenGL ES 2.0/1.1, OpenVG and OpenCL as well as the next generation of OpenGL ES, codenamed ‘Halti’ and Microsoft DirectX. The Nova A9600 is sampling in 2011.
The Nova A9540, built in 32nm, uses a dual-core Cortex-A9 running at up to 1.8 GHz and delivers graphics performance up to four times that of the U8500 and is sampling H2 2011.
The Nova A9500, built in 45 nm, uses a dual-core Cortex-A9 running at clock speeds of up to 1.2GHz, with Mali™ 400 improving graphics performance up to 20 percent, supporting full HD camcorder capabilities and up to 20 megapixel cameras. It is sampling and in design with ST-Ericsson customers today.

竞争激烈啊 PowerVR Nvidia ARM的Mail 都不断竞争。反观桌面的 AMD 和 Nvidia 就不激烈了。

实际游戏能有300%——500%就算它厉害。专门基于pv6的demo除外。
