Potential good farming tool.....!!

Intel Woodcrest processors will feature 1066MHz or 1333MHz processor system bus (PSB) depending on the model and will also have thermal design power (TDP) of 80W. The new chips will have two execution cores and will be made using 65nm process technology. The initial lineup will include models 5110, 5120, 5130, 5140, 5150 and 5160 that will operate at 1.60GHz, 1.86GHz, 2.00GHz, 2.33GHz, 2.67GHz and 3.00GHz, respectively. The chips will feature 4MB unified L2 cache, 1066 or 1333MHz PSB and will have TDP of 80W or below.

Intel Woodcrest processors promise to feature enhanced performance and moderate power consumption, two peculiarities that are expected to increase demand for the new Xeon central processing units and put a lot of pressure onto AMD Opteron processors, which have been gaining popularity in the most recent quarters. Besides, Woodcrest chips will feature rather aggressive pricing: the top-of-the-range model 5160 will be priced at $851, while the 5110 will cost $230 in 1000-unit quantities. The remaining 5120, 5130, 5140, 5150 models will be quoted at $700, $470, $330 and 270, respectively.

I know! The power savings will be insane! Check out some of my various machines I've hooked up to a Kill A Watt meter here. Looks like it's time to get rid of all the Athlon MPs, A64 X2s, P4 Northies, and Xeons I've got sucking juice around here! Probably keep one of each for "nostalgia" sake.

Of course this is all speculation at this point in time, but I see a chance to do some cheap overclocking on them simialr to what the laptop overclockers are doing with 400 fsb Dothans in Sonoma class laptops by a pinmodding for a higher fsb. Buy the cheap 1066 fsb Woodcrest then pinmod it for 1333 Mhz fsb. I imagine it will have to be done on the mobo though, since it's an LGA socket design. But that would get you some decent overclocking even with a mobo that doesn't support fsb adjustments.

Basically, a 3GHz Woodcrest chip gives you 3 billion x 4 FP ops x 2 cores per second, or 24 GFLOPS theoretical peak (Rpeak number in Linpack) per socket in 64-bit precision.

So, two chips on a typical workstation or server board give you 48 GFLOPS Rpeak - almost as good as a quad-chip Montecito, or 50% better than dual-chip (four cores total) POWER5+.

With the rumoured improvements, Woodcrest is hitting 80% efficiency in Linpack, i.e. its measurable Rmax rate of execution will be four-fifths of theoretical peak, or over 38 GFLOPs in this case.

Now, the 2.8GHz dual-core Opteron grade, expected to be the one greeting Woodcrest, has some 88% efficiency per socket, but the Rpeak per clock is half. So, it is 2.8 billion x 2 FP ops x 2 cores per second, or 11.2 GFLOPs Rpeak per socket. For two-socket Opteron, the Rpeak then would be 22.4 GFLOPs, and Rmax some 19.8 GFLOPs - half that of Woodcrest two socket setup! Wow, AMD should have had K8L now, not in a year's time.

We all know that Itanic is darn great at least in Linpack, with over 90% efficiency in some cases - but its clock is nearly half that of Woodcrest, with the same peak FP rate per cycle anyway. So, for a dual-core 1.6GHz Montecito, we have 1.6 billion x 4 FP ops x 2 cores per second, or 12.8 GFLOPs Rpeak per socket. Times 0.9 for Rmax, we have 11.5 GFLOPs Rmax per socket, or roughly 23 GFLOPs Rmax per two-socket board.

And 2.2GHz Power5+? Let's say 77% efficiency in this case. Dual-core chip too, so 2.2 billion x 4 FP ops x 2 cores per second, or 17.6 GFLOPs Rpeak, and 13.5 GFLOPs Rmax per socket, or 27 GFLOPs per two-socket board.

In summary? Woodcrest will, socket for socket, outperform all other CPUs in the market, X86 or RISC or EPIC - when it comes to the TOP500 battle and its Linpack benchmark.

So what processor is best now I know it used to be AMD chips gave you allot more ppd over intel systems. At that time all the big guns used AMD for there farms. Is Intels processors doing the same work as AMD processors now? Or is it just a matter of ppd to cost ratio people are looking at more now?
