Revolution vs. Xbox One
So, Revolution specs have been leaked onto IGN's site. The quote that best describes the specs is the following: "As soon as we find out what it can do then we'll know if Revolution will just be like an Xbox or something a little more." To me, these specs are quite disappointing. If you aren't disappointed, then you don't appreciate the new gaming experiences that increased power can open up. Complicated physics? No can do. Realistic reflections? Ha! Normal mapping? Laughable! Hundreds of enemies? Sorry, wait for Revolution 2 (or buy a PS3 or Xbox 360). Since I like speculating on the Revolution, let me tell you if it'll be like an Xbox or something a little more.
Processor
The Revolution has a processor that's possibly twice as fast as the GameCube processor. GameCube has a 485 MHz PowerPC, so let's assume the power is like a 970 MHz PowerPC. Xbox has a 733 Mhz. It's difficult to compare different architectures just based on clock speeds, but since the Xbox 1 got about twice the CPU performance of GameCube, I'd say they are the same.
Winner: The same.
GPU
No details have really emerged, but IGN reports that the Revolution dev kits are just GameCube dev kits at the moment. Let's assume that the GPU is a souped up version of the current GPU. The current GPU isn't nearly close to as good as the Xbox GPU, which features shaders and all sorts of goodies that GameCube lacks. So, although it's not obvious what the clear winner is, I'm guessing they'll be similar in power.
Winner: The same.
RAM
Revolution has 88 MB of useful RAM along with the 16 meg of slow ARAM according to IGN. Xbox has 64 MB.
Winner: Revolution!
HDTV support
Revolution will support 480p. Xbox 1 supports 480p, 720p and 1080i. Miyamoto has claimed that people can't tell the difference... I don't know what mushrooms he's been eating, but you can totally tell the difference between a 480p game and the higher HD resolutions.
Winner: Xbox
Controller
Yeah, yeah, yeah, everyone is claiming that the Revolution controller is the greatest thing since the joystick, so MAYBE I'll let the Revolution win here. But really, what good is the controller if no one makes games for it? Most development studios aren't really enthused about making games for it. Sure, the big companies release press releases saying they will develop for it, and individual people say how great it is, but I'm betting most of the game developers who praise it won't actually make games for it since it is their studio's decision, and most studios (that I know of... Sure, I don't know everyone, but I know a good slice of game developers) aren't doing Revolution games. You can do a cross plat game for PS3 and Xbox 360 and hit a large target audience, or risk it all on one platform that might not actually have good market penetration... So, most studios aren't going to want to do it, especially because a lot have already started developing next gen tech. They aren't going to abandon it and go back to their current gen tech for Revolution, are they? Maybe that's good because Revolution will get some fresh, new developers, but on the other hand, the new blood will be inexperienced and might
make mediocre games...
Winner: Uncertain
Well, there you have it! The Xbox has better HDTV support, but the Revolution has more RAM. Otherwise, they'll probably be comparable. The one ramification of the poor hardware specs is that Revolution won't get ports. That's someone good because titles will be able to utilize the controller more, but it's also bad because there won't be very many games for it...
