Xbox Portable Specs for 2008
Published: March 20, 2006, 12:23 PM CST

There are some solid rumors of an Xbox handheld game system in development.

What kind of hardware specs would it include? Microsoft could either squeeze the Xbox 360 hardware down into portable size or base the handheld on a new design. Full Xbox 360 hardware is many years away (~2015) from working affordably and with decent battery life in a handheld size. To have Xbox Portable release sooner (2008), the CPU would likely be based on new architecture (e.g. Transmeta, ARM). ATI would be my first guess for the GPU, but PowerVR is also possible.

I doubt that it would have an optical drive (DVD), as that adds unnecessary size and drains battery. Music, movies, and games should be downloaded to the internal storage (or memory cards). In other words, you'd be able to play games downloaded from Xbox Live Arcade/Marketplace. Another option is to have games distributed on carts like DS. I'd imagine that HD-DVD movies could be ripped (i.e. Managed Copy) to the portable Xbox.

I like the idea of running the same games (Live Arcade) on the home console (X360) and the handheld (Xbox Portable). That's similar in ways to playing the same games on a desktop PC and a notebook PC, watching the same DVD movies on a home player and a portable player, or listening to the same music on a home stereo and a portable MP3 player.

Does Microsoft have to squeeze the full Xbox 360 specs into the handheld? Could there be another solution? Do Live Arcade games have some processing limitation?

Known: Live Arcade games must currently fit within 50MB storage.
Known: XNA Framework allows managed code to run on multiple platforms.
Rumor: Original Xbox games will be downloadable from Live.
Likely: Xbox Portable will have low-resolution display, maybe 640x360.
Likely: Multiple versions (ports) of the same game could be on Live servers.

What does that tell us?

Games that fit within 50MB storage probably won't need 512MB RAM. Xbox Classic games are single-threaded and use no more than 64MB RAM. A gaming handheld in the next few years with screen size around 4-5 inches won't need 1280x720 (720p) resolution. The same games could be playable on a Windows PC, Xbox 360, Xbox Portable, and devices (e.g. cell phones) running Windows Mobile.

Now it's time to put together some estimated specs for the Xbox handheld. One CPU core is enough for single-threaded games. Main RAM size can be as low as 64MB, but 128-256MB should be doable. The GPU should be designed for low-resolution pixel rendering.

Estimated Specs
Transmeta or ARM CPU at 500-1200MHz
ATI GPU at 125-300MHz
128MB 250-600MHz DDR2 RAM
Internal Storage (8-16GB Flash or 20-80GB HDD)
3.6-4.5" Widescreen 16:9 Display (480x270 or 640x360)
Directional Control, Buttons
WiFi (LAN) and WiMAX (WAN)

Those specs may be possible in 2008 or 2009.

I like how the battery life and size are rather conveniently left out. It's not like they're important to handhelds anyway, I suppose.

If it uses flash memory and no optical drive, I see no reason it won't have decent battery life.

I was thinking about the screens and the specs.

How do you think that the load times would be?

I heard mentioned somewhere that the PSP's loadtimes were rediculously long.

By the time it comes out though, wouldn't the processors have got quite a bit more advanced?

Wouldn't be a very portable much less handheld unit anymore with 4-5" screen and use optical discs.

Any speculation or ideas on the physical design?

Clamshell, Slate, Convertible, or Slider? With a slate design, the screen and any buttons would always be visible.

How about the top of the clamshell folds completely back? The screen, buttons and analog sticks are all on the bottom, and the triggers and shoulder buttons are on the top, which when open becomes the back of the unit. That way, the triggers won't impede on the closed design and makes the handheld easier to fit into your pocket.

Also, if you use this design, the battery and the memory card slot/internal memory can be housed in the top of the clamshell. This leaves the bottom exclusive to the screen and the hardware.

Maybe rather than using a thumb stick they would implement a wheel sort of like the iPod, and then they don't need to be so thick, and keeps it flat. Same may go with the buttons, maybe something like the iPod center buttion would work well.

If I was to make a guess based on my perspective of where technology and gaming has been going, here's what I think might resemble the Xbox handheld (not including specs)if it came out around 2010 or 2012.

It will be a very slim (1/4" or less) device with one screen and no buttons. The entire area, including the screen will be touch sensitive. It will be simplistc and give the appearnce of being more of a thick peice of paper that you put into your pocket. It will be scratch resistant and bendable. Meaning, you'll be able to bend it to the point that the general popluace will be awed by its ablility to be bended. It will not use insertable media. All games will be downloaded to the handheld from some kind of a device, possibly a kiosk at every store it's games are sold.

Woah! That's like Year 2000™ stuff!

Bendable OLED or FOLED screens can be done. They can be rolled up like paper or put on clothing. But I've not read about any technology in development that would allow bendable processors, memory, and storage. Maybe some sections would have to be rigid. But anything's possible.

If the handheld is just one screen and no buttons, the priority should be a haptic multi-touch screen before trying to make it bendable. That would allow directional controls and multiple buttons on the screen that feel like buttons. It would probably involve vibration motors behind the screen.

with see through or transparent metal out now and so many leaps in materials it seems possible, but rigid sections don't seem like a drawback if they come with a natural cost advantage.

What would the graphic be like on a handheld like that? An Xbox-like quality?

More Speculations:

Xbox Live Wireless
System linkable with other Xbox brand consoles, not just handhelds.

Steve, how much do you expect such a device to cost?
March 28, 2006, 9:08 AM by saycheese to moofoo3
Howmuchever powerful the system might be, it won't gain mass market if the price goes north of 200-300USD. 400 bucks would be really pushing it, unless Microsoft manages to pull an iPod-esque surprise, effectively combining gaming, audio and video capabilities in a PSP-esque form factor.

Just improve the PSP and the iPod, and do it right without ducking around with new disc formats with limited usability. Price it alongside the iPod and the PSP and just make them play games. Reap the gold.

Anywhere from $200 to $400 is possible for Xbox Portable at launch. There may be two models with different size HDD, possibly flash in the cheaper model.

Xbox Portable would surely link with Xbox 360.
