Evaluation of the 45nm AMD Deneb Reveals an Efficient Processor in the Making
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.
CPU-Z Identification
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.
Power Consumption
Specifications of the test-bed are provided. The 65nm Agena part was compared to the 45nm Deneb at the same clock-speed, idle and load consumptions were measured (first chart: idle, second: load):
Benchmark Scores
Fritz Chess (higher is better):
W-Prime Multithreaded Benchmark (time, lower is better):
POV-Ray 3.7 beta23 SSE2 (higher is better):
H.264 Encoding (time, lower is better):
3DMark Vantage (CPU score, higher is better):
The test bed was configured as follows:

if someone is buying on a budget the E2160 kicks ass for its OCability, but if they're concerned abotu warranty or have no intention to OC then AMD certainly has a place there.
its not like AMD are useless, its just that in most situations theres a reason to go intel over AMD... and some of those will go away if those new wattage numbers are true.
that test was done with SB600 mobo so Deneb and SB750 would
lower the power draw even more
3 minutes later....
He's on vacation for 2 weeks.
Though I´d like to see power consumption for the 3.2 GHz OC.
Anyways, killing ~50% energy appetite sounds record-breaking to my ears.
