Here the 2.7GHz Conroe based system is shown getting 11411 3DMarks. Granted with very overclocked graphics cards, but it appears that the Conroe system is really unleashing the full power of the Crossfire system (and this is on a poorly supported, pre-release mobo).

Here is the first sighting of a B0 stepping 2.67GHz STOCK Conroe. Check out the CPU score in 3dMark06! 2282 stock @ 2.6GHz!!! FYI, The overall score is very low becuase it is running the integrated motherboard graphics. I can't wait to see this with a 7900GTX or something!

3.2GHz "Conroe" gets confirmed by Intel
Intel representatives just contacted DailyTech with the following information:
The Core 2 Extreme processor (Conroe based) will ship at 2.93GHz at Core 2 Duo launch. We will also have a 3.2GHz version by end of the year. And as you know, the Quad Core enthusiast SKU, Kentsfield, is planned for Q1'07.

Energy Consumption:
The 1.83, 2.16, 2.40, and 2.67GHz models have a 65W TDP, the 2.93GHz Extreme Edition has an 75W TDP. For reference, Intel's current top of the line Pentium Extreme Edition 965 has a 130W TDP and AMD's FX-62 has a 125W TDP. Even though Conroe seems to completely demolish these chips in performance, it uses nearly half the power.

The "So what makes Core so new?" Section:
Here I will try to present some of the differences between CORE and previous architectures (in particular, the Core Duo, Intel's most current architecture you can buy today).
Conroe features a large 4MB cache, which is a first in consumer x86 products. This cache also has ultra-fine-grained power control, and an intelligent sharing mechanism between the two cores (in fact on some motherboards you will see that you can turn off one of the cores and dedicate the entire 4MB to one core, for more stablity in ultra high overclocks for single threaded apps. I can't provide proof for this statement yet, but you'll just have to wait and see if I'm right). That power control and sharing mechanism is not a walk in the park to design, and while many of the principles are present in Core Duo, this was a complete redesign with more aggressive power saving algorithms and more sensors and much more fine grained control, meaning smaller sections of the cache can be turned off more frequently.
Conroe also features memory disambiguation which allows most Loads to be speculatively executed before Stores. This is a HUGE benefit for some workloads. This is also not present in Core Duo.
Conroe has a 4-issue core, which means that 4 (or in some cases 5, see below) instructions are simultaneously pulled from the instruction cache and fed through the pipeline. Core Duo (and every other x86 product on the market) is 3-issue.
Conroe has macro and micro-ops fusion which allows certain combinations of x86 ops to be combined into one as they are pulled from the instruction cache. Macro-fusion allows the chip to save energy and have higher bandwidth, particularly during popular CMP-JMP operation pairs (if/then or switch statements in most programming languages decode into these instructions). It saves energy because it can literally do the same work with less physical transistor switching as the fused instruction moves through the pipeline. Core Duo only has micro-fusion.
