Xbox One CPU

It’s safe to say that the Xbox One eclipses the 360 in all aspects. A system such as the Xbox One can boast impressive figures and software capabilities, but all of this is possible due to the core of the machine. I am of course referring to the Xbox One CPU.

Before we take a look at the Xbox One, let’s focus on the 360 and what that the current generation brought us. Designed by IBM, the CPU is triple-core, 64-Bit PowerPC based. Each core boasts a rather mammoth 3.2GHz. The SIMD vector processor evolved from the original Xbox and includes a dot-product instruction, which takes far fewer latency than its predecessor. It was also given the addition of D3D (Direct 3D). Pushed to its absolute limits, it manages 115.2 gigaflops and has the power to produce 9.6 billion dots per second. To bring down costs but raise power the processor uses in-order execute processes, as opposed to the out of order execute processes of the original Xbox. The CPU houses ROM which stores encryption keys used for game data. 360 devotees will also remember overheating problems caused by first generation 360’s 70mm twin fans, which was later changed to a single side mounted fan. Each slight redesign of the console has seen slightly altered fan style and configuration, which suggests that Microsoft never did quite get ahold of the famous red ring of death problem which plagued early consoles.

Xbox One CPUThe Xbox One CPU is set to be nothing short of immense. The behemoth of the CPU world, if you will. We’ve heard that the Xbox One will have a mighty impressive 8-core 1.6GHz processor.

“But you said the 360 had a 3.2GHz CPU!” I hear you cry.

As technology and our understanding of technology grows, developers learn how to better harness that technology (which makes them sound like a super villain). The fact that the CPU is less than half the size of that of the 360 is not important.

To put things in to perspective, the Wii U only has a 1.4GHz processor.

It's likely that the Xbox One CPU will be AMD Jaguar-based, which is what the console's biggest rival, the PS4, is also home to.

In fact, many are predicting that they will be scarily similar to that of Sony’s PS4, and we know that those figures went down well during the consoles unveiling in March.
“They’re copying them,” I hear fanboy’s around the world cry.

And to that I say: “Shush.”

It may not be something Xbox fanatics like to admit, but it is rumored that the Xbox One will only house 12 processing clusters, as opposed to the PS4’s 18. So what does this mean for graphics? Will the One’s graphics suffer as a result?

Not likely. The Xbox One will be fitted with an AMD Radeon 7790 chip, so while the system may not have the same amount of processing clusters as its biggest rival, it will have greater speed, which will mean that there will be very little difference when comparing the two consoles side by side.

Of course, with talk circulating that the heart of the Xbox One will be windows based, anything is possible at this stage. Perhaps, finally, PC gamers will see their allegiance to the mouse slide to the dark side of the controller? While consoles will never be able to keep up with PC’s, the One is certainly looking to close the gap. PC gamers familiar with the X64 should feel right at home when using a One.

This also means less power is required, which subsequently means less heat is produced. That, my fellow Xbox aficionados, means we hopefully won’t be experiencing those 3 little red lights we all know and love*. (*hate.)

Let’s take a look at the Xbox One CPU stats:
8 Core, X64 at 1.6GHz, 4MB L2
GPU D3D, 800 MHz

Now who could possibly argue with that?

With the PS4 CPU already announced Microsoft has had plenty of time to come up with something equally powerful.
