It's fighting to keep up with the PlayStation 4
Microsoft gave its upcoming Xbox One console a graphics performance boost in an effort to compete with
the PlayStation 4
Xbox Live VP Marc Whitten said that the Xbox One's GPU clock speed is now 853MHz, up from the previous 800MHz.
While Microsoft seems to be making an effort, it still doesn't quite touch the PS4. According to
, the PS4 still beats the Xbox One in raw graphics power by about 40 percent.
Microsoft also announced other changes, such as a "mono driver," which is supposed to be a 100 percent optimized graphics driver for the Xbox One.
Microsoft announced its
Xbox One console
in late May. The new machine will feature an APU with eight x86-64 cores; 8GB of DDR3 RAM; a GPU based on an AMD GCN architecture; a 500 GB non-replaceable hard drive; three USB 3.0 ports; HDMI, and a Blu-ray optical drive.
Sony announced the PS4 in June, which is a $399 console featuring an 8-core 64-bit x86 Jaguar CPU built by AMD; a Radeon GPU comprised of 18 compute units (achieves 1.84 TFLOPS); a 6x Blu-ray drive; 8GB of GDDR5 of unified RAM; USB 3.0; Bluetooth 2.1; HDMI; optical out, and 802.11n Wi-Fi.
Sony has been ahead of the game with the PS4 thanks to the Xbox One being more expensive, having more DRM and being slower. The Xbox One has received a lot of criticism for the restrictions it placed on gamers, such as
the used games ban
and the new "always-on" digital rights management (DRM) system, which posed a problem for many people who are either in rural areas with slow Internet connections, travelling or experience Internet issues with providers. Microsoft later
retracted these features
after major complaints, and is now working to keep up with Sony.

It wont be able to match the sheer bandwidth of the PS4. Memory bandwidth is why video cards have thier own memory and cant use system memory. It's just too slow, yet here the the XBO using std dram for it...
MS is expecting it to be slower , thus why they are trying to up their specs to look better. It wont be that far off though, not a huge difference. I would worry more about MS's BS policies and potential failures than the speed of the GPU.

You are also forgetting that video memory is used differently. GPUs tend to render texture data which can be sampled linearly in memory maximizing spacial coherency, thus high bandwidth memory is more effective because you are basically just streaming data.
System memory is far more random access, and while cache coherency plays a large role for faster access, it's not uncommon to read one integer from a chunk of memory then have the next access be megabytes away in addressable space. Here, high bandwidth is not as important as low latency access.
You also must have missed the article about how the ESRAM in retail devices is expected to have a higher throughput, greater than the PS4's bandwidth using GDDR5:
