Revolutionary: Respectable Specs

Every Tuesday, Mike Sylvester brings you REVOLUTIONARY, a look at the wide world of Wii possibilities.

Nintendo still hasn't confirmed any of the technical specs of the Wii hardware in detail, and we wouldn't recommend you hold your breath until they do. They don't want people making assumptions of what the system can or can't do based on arbitrary numbers and jargon. We do know that the Wii is much more than "two Gamecubes taped together." In addition to the revolutionary controllers, we get integrated Wi-Fi, 2 USB 2.0 ports, 48 MB more RAM, internal flash storage, an SD card slot, full-sized DVD disc capacity, and a new operating system and GUI that brings us software like Mii Channel, Photo Channel, Forecast Channel, and Internet Channel. Wii Shop and Virtual Console could not have been done on Gamecube, and with support for component output reintegrated, we can enjoy our old and new games in glorious 480p. That's a pretty long list of upgrades over the Gamecube, and it's in a smaller, more attractive package.

With 50% faster GPU, CPU, and memory speeds, Nintendo didn't make quite as large a leap beyond their prior console as Sony and Microsoft did, but they made their design decisions to keep production high and prices low. That's not to say the hardware can't produce epic games with great graphics.

729MHz IBM PowerPC-derived CPU, codename "Broadway" manufactured on a 90nm SOI process
243MHz ATi-designed GPU (now AMD), codename "Hollywood" manufactured on a 90nm process
3MB eDRAM and 24MB 1-T SRAM on the GPU
64MB GDDR3 external "A-RAM"
512MB NAND flash memory
SD card reader for storage expansion
8.5GB DVD9 optical disc drive
802.11b internal Wi-Fi adapter
Bluetooth internal wireless I/O adapter

These days, a 729MHz single core CPU practically warrants a "pshaw" and a dismissive wave of the hand. Some developers wouldn't get out of bed for less than 2GHz. But (as CPU manufacturers have been forced to admit in recent years) clockspeed is not all that matters. The Broadway is a RISC architecture, so by nature it can do more with its roughly 730MHz than the CISC Xbox CPU can. When we first heard the Nintendo 64 would be deviating from console tradition by using a RISC processor, we were directed to look at Macs as an example of one such architecture. To put the Wii's power in perspective, I started learning Photoshop in college on a 366MHz PowerPC G3 Mac, which had only 64MB of RAM. (And we liked it!) Doing my homework on a 550MHz Intel system didn't make filters and effects render any faster. A ~730MHz PowerPC-family chip is no slouch when it comes to general purpose applications, and apps like the Internet Channel, the Photo Channel, and Everybody Votes can be considered general purpose. The Mac platform was never strongly marketed for its games, but that's not for lack of power. To the contrary, id Software made the grand unveiling of Quake 3, one of their most popular PC games, on a PowerPC-based Mac. And while the "competition" has since adopted PowerPC-based architectures, they're still taking a more brute force approach and pricing themselves right out of the hands of eager gamers.


"Hollywood" is a dual-chip configuration, which doesn't look dissimilar to the Xbox 360's "Xenos" GPU. However, the 2 chips that comprise the "Xenos" package are both dedicated to graphics processing, while one chip ("Vegas") handles I/O, RAM access, and graphics processing, and the other ("Napa") integrates the audio DSP with the 24MB pool of 1-T SRAM. It's definitely not in the same class as the "state of the art" GPUs in the PS3 and Xbox 360, but it's not quite the relic some would have you believe. Its TEV engine performs the functions we would normally expect of the pixel shaders and texture units in more common GPU architectures. It can work with as many as 8 texture layers per pass (specular maps, diffuse maps, normal maps, etc.), so it's quite possible to have bumpy, shiny graphics at least equivalent to what the Xbox can render. We've seen developers making use of the EMBM effect of the hardware, and Starfox Adventures already showed us how well the hardware can handle fur shader effects.


Now, it's a little confusing that the 24MB of 1-T SRAM that was the main system memory for the Gamecube has been moved onto the GPU package in the Wii. We also have a flip-flop in the configuration where the external auxiliary memory is now in greater capacity than the internal system memory. That increase, along with an increase in bandwidth, gives the external memory more versatility. The 16MB pool of 1-T SRAM in the Gamecube was fairly limited in functionality, and commonly thought of as a buffer for audio samples. It's a strange prioritization having 16MB for audio and 3MB for graphics, but there just wasn't enough bandwidth in the A-RAM to use it for much more demanding tasks. That problem has been addressed in the Wii where the A-RAM bandwidth matches that of the system memory.

Both Xbox 360 and PS3 have multiple gigabytes of hard drive space to use as a cache for loading data faster than is possible directly from the optical drive. Wii's A-RAM can be used in the same way. 64MB isn't much, but it's 4x more than the Gamecube had, and it allows even faster access than the hard drives in those other consoles. What does that mean for games? Maintaining the same quick and/or infrequent load times we had on the Gamecube, we could have larger levels, or levels that are filled with more objects.

What about higher resolution textures? Well, not so much ... Yes, we can pull those off the disc into the A-RAM, but when it's time to apply the textures to models and the world, we're still stuck with the same 3MB of eDRAM on the "Hollywood" as we saw in Gamecube's "Flipper." Usually, it's divvied up 1MB for texture caching and 2MB for z-buffering and frame buffers. It doesn't necessarily curse us to textures worse than on the PS2. Although the PS2 has 4MB eDRAM for graphics, it doesn't employ texture compression. Wii and GC's S3TC can make the 1MB of texture cache seem more like 8MB, and with a greater range of colors than we see in PS2 textures.

We could have lived with the slow CPU and GPU. We could have bought a Wi-Fi network adapter and wireless Remote controllers. We could have played games spanning multiple 1.5GB mini-DVDs. But what really makes the Wii more than just a "Gamecube 1.5" is the internal flash memory. For the first time, we can upgrade and instantly get new games for our Nintendo systems without leaving the house. The flash memory can store system software updates and new channels that enhance the functionality of the system. We can create levels and trade them through WiiConnect24, or potentially download extra content from the game developers. And it makes the Virtual Console possible.

When we take in the whole picture, it is evident that Nintendo doesn't intend for the world of Wii possibilities to be populated with just PS2 ports and minigames. Epic games with online multiplayer, downloadable content and improved graphics are all apparent in Nintendo's upgrades to the Gamecube base hardware. "So where are these games?" you cry. "They're comin'!" was Nintendo's reply at E3. You may not have heard it over the sound of them patting themselves on the back, but they did show more of Super Mario Galaxy and gave us release dates for it and Smash Brothers Brawl, and thankfully didn't announce anymore delays to Metroid Prime 3.

It's pretty clear in my mind that when Iwata-san was presaging our first impressions of the Wii's graphics rendering aptitude, he was thinking of Super Mario Galaxy. The graphics certainly make us say "WOW," followed by a *thud* and then silence as our jaws hit and remain on the floor. Nearly every surface is coated with sharp detail textures and EMBM effects. The artistic use of rim lighting plays well with the celestial motif and makes Mario look seriously out of this world!


Metroid Prime 3: Corruption is shaping up to raise the already stellar production values set by the first 2 Metroid Prime games to even higher heights. Instead of getting the narrative from scanning artifacts and scenery for transcribed histories, we'll be interacting with live people that actually speak and join us in the intense action. And there's guaranteed to be plenty of shooting, now that we have a nifty controller that works for aiming. The color palette is much more vibrant this time around, and it's Metroid Prime, so you know you're going to be saying "WOW!"

Smash Brothers Melee sold more units than any other Gamecube game, so I'm sure you're as impatient as we are for December 3rd to come. The sales figures of Smash Brothers Brawl will show the world that it's not just senior citizens lining up Saturday night outside of Target to take home a Wii on Sunday morning. Unless our grannies, too, have been fervently waiting to make Snake bust some CQC on Pikachu. We're still looking forward to finding out what modes will be supported, while anxiously anticipating Wi-Fi matches. In the meanwhile, we'll have Mario Strikers: Charged and BWii to satiate our online multiplayer hunger.

We're counting on Nintendo to school third parties on how to make deep games with stunning graphics. The hardware's capable, but do you think Nintendo's setting the right example? Do you think third party developers will broaden their lineups for us? Give us your view in the comments.

This was just a really long post stating how much the Wii sucks compared to the 360 and PS3. No matter what anybody says, it won't be able to play in the same league as the PS3 and 360.

Cereal&Milk

Ignorant? Very. It's an article that practically hacks the "GameCube 1.5" claims in half and incinerates the left overs. It's just stating that the Wii has potential to deliver truly outstanding visuals even though it's meak in comparison to the others.

At the very least, this proves that it has the power to out-do the first XBOX.

So this is why Mario Party 8 lags like hell?

No. It lags like hell because of poor optimization (tsk, tsk Nintendo), sort of like how Rappelz has the ability to lag on high-end rigs.

Haven't read the whole thing cause I got to leave for work soon, but the biggest thing people forget about electronics is that there are different architects, and different architects can allow fast speeds in various of ways.

There are already chips that have far surpassed 8GHz on default clock speed, but they are also slow as hell because it's simply a different architect.
Something like GHz is only worth measuring speed when you're talking about the same architect. It's pretty much impossible to compare the speed of two different architects. They work in completely different ways, therefor the "specs" mean completely different things on each.

All of those numbers that the other companies spout out is just them bullshitting.

The problem is that the 3rd party devolpers think that the Wii is Gamecube 1.5 and so are only making party games and shity ports, while Nintendo is still trying to find the potential of the Wii.

Nintendo knows the potential - they produced it. It's the developers that are using the motion controls as an excuse for releasing shitty games. There are very few from 3rd Party developers that are even worth buying and I'll admit that. Hopefully someone will step up and make some great shit for the system.
