Chinese website Hardspell conducted a comprehensive pre-release evaluation of the upcoming Deneb 45nm Quad-core processor by AMD. The Deneb core incorporates thrice the amount of L3 Cache (that’s 6 MB), and uses the same SIMD sets as its 65nm counterparts.

Here’s a shocker: While the Phenom X4 9650 (65nm, 2.30 GHz, B3) consumes 104.1 W at load (peak), the 45nm Deneb (45nm, 2.30 GHz) peaks at an astonishing 57.3 W according to Hardspell’s findings, go to see, the Deneb has an added load of transistors due to a 300% increase in the L3 Cache size. Let’s bring in some numbers and figures.

Version 1.46.2 and above of CPU-Z detects the processor except the CPUID string which the engineering samples don’t usually bring along. The 2.30 GHz Deneb Part comes with a 1.80 GHz HT link with 3600 MT/s of system bandwidth over the HyperTransport 3.0 bus. The L3 Cache uses 48-way set-associative paths.
