NVIDIA 第四代 Tegra —— Wayne 强大到令人难以置信

Even though Kal-El hasn't even launched yet, we have received some preliminary information on NVIDIA Wayne. You're free to take this information with a grain of salt, we're just the messengers here.

NVIDIA's Public Tegra Roadmap Shows 28nm Wayne Arriving in 2012, ahead of Logan and Stark

T40 is 4th Generation Tegra, said the people, who asked not to be identified because details are confidential. The prototype Wayne silicon will be released to manufacturers and software developers in December 2011, in order to get ready for the Windows 8 release in October 2012. With Wayne, NVIDIA plans to target smartphone, tablet, netbook and [color=#000064 !important][color=#0064 ! important]notebook market. In order to do just that, the company decided on Batman/Robin strategy, i.e. developing two silicons.

The initial silicon is a quad-core design based on a yet undisclosed ARM architecture. There are two choices: NVIDIA licensed Cortex-A15 and own in-house 64-bit architecture. Given that Project Denver is scheduled for tape-out by the end of 4th quarter - we doubt it. It is safe to assume that Cortex-A15 is being used.

Initial silicon also features "at least 24-core" CUDA-enabled GPU part which resembles contemporary GPU architectures, bringing a lot of [color=#000064 !important][color=#0064 ! important]computing [color=#0064 ! important]performance. The people said that the "10x" performance increase (from Tegra 2) includes a lot of GPU computing power, which is being used for numerous segments. One of such uses was motion-picture sharpening a'la CSI i.e. technology similar to what MotionDSP developed. Lightfield focusing technology was also mentioned to us as "the next big thing" in mobile - and processing side will handle Lightfield on-the-fly using GPU cores.

This first silicon is targeting the 1.5GHz clock for the ARM cores and packs triple-digit GFLOPS number. Given that the competition already announced 2GHz and 2.5GHz parts based on Cortex-A15 [color=#000064 !important][color=#0064 ! important]CPU core, we asked wouldn't 1.5GHz clock prove uncompetitive. The answer was that 1.5GHz is targeted for core-per-core comparison with the A9-equipped "Kal-El" T30 and that final clock speeds depend on the power consumption as the "Robin silicon" needs to keep the same power envelope as Kal-El.

Second Wayne silicon can be described as "Holy Smokes Batman". Unlike 4/24+ "Robin", NVIDIA's is planning an 8CPU/32-64GPU part for tablets, netbook and ultra-low-power notebooks. Think up to 13.3" in screen size. We were confused by the "up to 64" claim as NVIDIA's contemporary Fermi architecture is designed in 32 and 48-core blocks. However, in order to rea**e power targets, [color=#000064 !important][color=#0064 ! important]engineers are working to be as flexible as possible. Whatever the final design ends up being it is a DX11+ compliant part, with full support for OpenGL 4.x and OpenCL 1.x. Also, an interesting note is that PhysX was explicitly mentioned in the "we have full support for PhysX now" sense. Draw your own conclusions on what that means.

The 8-core ARM design is being designed to go head to head against not just ARM competitors, but against the X86 [color=#000064 !important][color=#000064 !important]processors as well. Remember, for Windows 8 Intel should cover top-to-bottom market with the next-gen Atom architecture (22nm Silvermont) on the low end and 22nm Ivy Bridge. At the same time, AMD plans 28nm 4-core Krishna and 2-core Wichita, both based on Enhanced Bobcat CPU core and a [color=#000064 !important][color=#000064 !important]32nm Trinity APU with dual and quad-core designs based on Enhanced Bulldozer core.

In a nuts**, Wayne is actually a split personality - quad-core Robin and octa-core Batman. No doubt, competitors will probably make a reference to Harvey Two-Face Dent.

骂x86的就别用电脑办公上网打游戏，通通用平板搞定
骂ARM的赶紧把自己的手机、相机、MP3之类的全扔掉。

有什么好吵的，arm和x86正在各自进军对方的领地，几年内必见分晓。现在吵得最凶，喊得最得意的人对结果也不会有任何的影响力。

本贴注定要被挖坟的。各位参与者就等着吧，建议稍安勿躁。

我本人，是倾向于支持arm阵营，将会把x86目前的市场吃掉一块，甚至一大块；但在4,5年的时间内，不会出现arm全面推翻x86的情况。5年后就难说了。
而移动的cpu市场的分量仍然是会越来越重，所以移动方面的arm影响也是越来越大。intel在这个领域还没取得过分数。

三八0同学，我还真是想听听您如何评价SW M500呢。

嗯，明白，在打开500张2M图片方面，重数十克的、拿在手里随时可用的手机要比连着市电电源插座、重数千克的PC慢好多好多。完全认同您的看法。

因此，您就评价ARM烂，还真是完美论证呢。

可是，重数十克的、拿在手里随时可用的手机在打电话方面对比PC又如何呢？

三八0同学老是觉得受了委屈，其实真没必要，三八0同学要比较性能，其实我只不过提醒三八0同学比较性能的时候应该考虑比较的前提和环境。这有啥问题啊？

长风

性能就是渣，o(︶︿︶)o 唉，您倒是另外找个性能不渣的手机用的CPU啊？

您到底为啥拼命认为别人是在反驳您呐？您开拓了一片新的讨论天地，就不许别人也开一个？
主贴说Tegra系列产品规划，您扯出个CPU的性能比较，从主贴里面，哪里能看出ARM性能烂了，您所说的性能烂到底是从何说起呢？跟谁比较呢？是否是您别开天地呢？

好吧好吧，你只不过说arm性能烂，错不在您。那能否请您明示，您“性能不烂”的标准到底是什么？哪种架构的CPU性能不烂。

长风

功耗低有PI用，o(∩_∩)o 哈哈

o(︶︿︶)o 唉，悲哀啊，悲哀

你说的性能烂其实本也没人说啥啊，只不过提醒你注意对比对象，还是那句话，您是否认为SW M500性能烂，跟您的ARM性能就是烂这个论点，是一个道理啊，您只要说句“SW M500真是烂”不就完了么？我就想听听您对SW M500的评价。
我这里本来也只不过说X86功耗烂么，不适合手机之类的应用，做手机就是没法用X86，我到底哪里说错了？

看样子你要往死里埋汰arm了。
