PotatoHog's daily lesson on the Wii U CPU/GPU situation

REPLY：

If the Wii U's GPU is 2x as powerful as the 360's but the CPU is the same performance, the system will actually be less than 2x as fast in graphical games. The system will probably be 50% faster in games than a 360. That's if the GPU and/or CPU are this fast, they might be slower.

I know this stuff because I have spent thousands on gaming computers and have ran various gaming tests. I like to think my lesson is a little better than what you'd learn over at Anandtech. Also, these are estimations and lowering the AI or even the GPU side of it can raise performance. The GPU can be used much better if games are 1080p but most games probably won't be because making a game 720p is easier.

AN OTHER：

Thats actually a pretty decent estimation
1.5x falls within the ballpark figure for the system.

Some info for you though. How much overhead does the 360 spend on audio? Sometimes as much as 33% of the cpu in many games is dedicated to sound.

Well, the wii u cpu isnt burdened with sound, the systems designed to offload the burden to a dsp that handles all audio.

Unfortunately, 360 ports cant do that, as the 360 cant, theyd have to reprogram the game instead of merely porting it, they emulate the 360's sound code through the cpu. Whoops.

How much cpu overhead does the 360 use on keeping the dashboard suspended? Xbox live features?

Wii u doesnt. It uses an arm coprocessor for os and system functions.

Something to think about.

背景：任天堂新一代家用机WIIU已于几天前发售，某些硬件相关网站已经第一时间放出WIIU 主机及GAME PAD的拆机图。鉴于WIIU采用全新架构设计，目前的技术力尚不能攻陷主机内部封装的显示核心数据。

在还没统一口径的前提下，任何关于WIIU 主机配置参数的说法都是不准确的。

目前最新的讨论进展为：

next-generation games at 720p on the Wii U will probably look better than current-generation games at 1080p would.
