Yesterday Microsoft finally took the covers off the new Xbox, what it hopes will last for many years to come. At a high level here’s what we’re dealing with:
- 8-core AMD Jaguar CPU
- 12 CU/768 SP AMD GCN GPU
- 8GB DDR3 system memory
- 500GB HDD
- Blu-ray drive
- 2.4/5.0GHz 802.11 a/b/g/n, multiple radios with WiFi Direct support
- 4K HDMI in/out (for cable TV passthrough)
- USB 3.0
- Available later this year
While Microsoft was light on technical details, I believe we have enough to put together some decent analysis. Let’s get to it.
Sony gave the PS4 50% more raw shader performance, plain and simple (768 SPs @ 800MHz vs. 1152 SPs & 800MHz). We’ll have to wait and see how this hardware delta gets exposed in games over time, but the gap is definitely there. The funny thing about game consoles is that it’s usually the lowest common denominator that determines the bulk of the experience across all platforms.
On the plus side, the Xbox One should enjoy better power/thermal characteristics compared to the PlayStation 4. Even compared to the Xbox 360 we should see improvement in many use cases thanks to modern power management techniques.
Differences in the memory subsytems also gives us some insight into each approach to the next-gen consoles. Microsoft opted for embedded SRAM + DDR3, while Sony went for a very fast GDDR5 memory interface. Sony’s approach (especially when combined with a beefier GPU) is exactly what you’d build if you wanted to give game developers the fastest hardware. Microsoft’s approach on the other hand looks a little more broad. The Xbox One still gives game developers a significant performance boost over the previous generation, but also attempts to widen the audience for the console. It’s a risky strategy for sure, especially given the similarities in the underlying architectures between the Xbox One and PS4.
