The next-generation Xbox will include an 8-core CPU, a DirectX 11.1-capable GPU, 8GB of DDR3 RAM and a Blu-ray disc drive, according to a new report.
The latest leak comes courtesy of VGLeaks.com, which claims to have received information on the unannounced console's "general components" and "some technical details".
According to the site, the next-gen Xbox features an x64 8-core CPU clocked at 1.6GHZ, similar to the processor alleged to be included with PlayStation 4.
The site also claims that "each CPU thread has its own 32 KB L1 instruction cache and 32 KB L1 data cache," and that "each module of four CPU cores has a 2 MB L2 cache resulting in a total of 4 MB of L2 cache.
"Each core has one fully independent hardware thread with no shared execution resources," the site continues, and "each hardware thread can issue two instructions per clock".
Meanwhile, an 800MHz Direct3D11.1 class graphics processor will allegedly let the system "issue 1.2 trillion floating-point operations per second", while 8GB of DDR3 RAM will provide a "peak bandwidth of 170 GB/sec" when paired with the system memory and 32MB ESRAM.
Interestingly, the site claims that a SATA 2.0 hard drive will "always be present", suggesting that Microsoft may not allow users to remove their hard drive, or offer a console without a hard drive attached.
A 6x Blu-ray disc drive capable of reading discs with 50GB storage space will also be included, the site alleges, and the hardware will include support for HDMI 1.4a, 802.11 a/b/n/g Wi-Fi and USB 3.0.
Kinect will also be supported.
And finally, "move engines" and "cryptography engines for encryption and decryption, and hashing" are also listed by the site as hardware accelerators support by the console.
Rumours emerge hours after VideoGamer.com reported leaked specs on rival console PlayStation 4.
VGLeaks has previously leaked details on Wii U's system specs and screens from Gears of War Judgment's debut trailer prior to it being aired.
The site claims it will reveal details on PlayStation Orbis, the rumoured codename for PlayStation 4, "next".
The next-generation Xbox is expected to be announced in around two months' time.
