CPU - Xenon's CPU has three 3.0 GHz PowerPC cores. Each core is capable of two instructions per cycle and has an L1 cache with 32 KB for data and 32 KB for instructions. The three cores share 1 MB of L2 cache. Alpha 2 developer kits currently have two cores instead of three.


3 X 3.0 GHz PowerPC cores

"Each core is capable of two instructions per cycle"

That means each core does 3,000,000 x 2 = 6,000,000 instructions per second.
So, all three combined do 6,000,000 x 3 = 18,000,000(18 Billion) instructions per second.

These PowerPC cores are 32 bit processors (not 32 + 32 + 32, just 32).  So, the instructions per second can be compared accurately to any 32 bit processor.

Amd Athlon XP 3200+ (32 bit)
1 Core @ 2.2 Ghz capable of 9 instructions per cycle.
2,200,000 x 9 = 19,800,000(19.8 Billion) instructions per cycle.

So, the Xbox 2's processor is slower than a Athlon Xp 3200+.

But, I don't understand why everyone thinks that MS is going to build a gaming console with all the hardware from a $2000 gaming pc and sell it for $300-350.  This console is going to rock, the processor isn't going to be the fastest retail processor ever made, but it will still kick most pc's asses.

5,131,000 instructions per second for the original xbox.
19,000,000 instructions per second for the Xbox-2.

Thats nearly 4 times as fast, and then you add a video card that is 4 times as powerful, and 4 or more times the ram (and faster ram at that).  What you get is one hell of a nice console.

I'd just like to remind those that have forgotten the specs for xbox

CPU: 733 MHz chip crafted by Intel
Graphics Processor: 250MHz XGPU, developed by MS and nVIDIA
Total Memory: 64 MB running at 200MHz DDR (Double-Data-Rate)

Its hard to emagine that people are still dissopointed in the specs for Xenon I mean come on from what we some what know about Xenon were looking at about 10 times more power than xbox if it were any more your looking at spending $1,000 so if your one of those that are dissopointed why dont you just get yourself a better PC not that it will help you any seeing how things are looking like Xenon will have more gameing power then most high end PC's that are available now

just remember there are no official facts about Xenon the only thing we know for sure is its gona be alot better than xbox

ok its obvious i need to explain some things at this point,

IBM has developed a revision to the G5 processor, and while the arch has changes somewhat, they are still labeling it as a G5. it features spus, similar to cell's around the ppc core. so in effect it is NOT a standard G5, and will be FASTER than a desktop g5 in boith general processing and graphics rendering thanks to the spus. i dont understand how anyone could think that a tri-core design with each running at 3 Ghz and and spus surrounding the core, is slower, than a desktop pc! trying to compare the two is like trying to compare the Gflops of a graphics card and the Gflops of a general processor! IT DOESNT WORK! you will get inflated numbers from a gpu  because it processes specific types of data. It doesnt work. the best we have to go on is benchmarks. which provide a much more accurate representation. I would also like to further add that the reason mac games get lower benchmarks is because they are all written in openGL and are not optimized for mac, but rather lazily ported to it. oh and yes the cell will have a single ppc but it also acts as a controller to the spus, handles  branch predicition, and various other processes in addition to its cpu duties, so it will be pretty taxed and occupied. its also worth noting that the cell ppc core is also built on the new arch and thus is not really comparable to a g5, or rather it will run fasteer than a g5

I still think the new xbox should have 512mb RAM. Imagine the possibilties for game modders once the system is cracked!

"I feel like making a new level for TES: Oblivion" damn, my computers down for the day. WAIT! I can open xbox-linux and use 3DSMAX right here on my xbox!"

Just wishfull thinking I guess.....

These cores aren't based on the G5, and they aren't 64 bit.
