First Looks at Athlon 64 4000+ & FX-55
CrzyP writes "AnandTech.com has benchmarked the new "Athlon 64 4000+ and the FX-55" in various areas including business application performance, audio/video, gaming, and much more in this first look at AMD's newest 64bit chips. Just after AMD's announcement, AnandTech posted this article to help consumers choose between Intel and AMD."

Why should Anand get all the attention?

This is actually the last resort, as the cost of wafer real-estate versus speed increase is low. You rarely do this for raw speed rather for special needs like Servers and the like.
The increase in the speed for a workstation is probably one speed grade at a cost increase of 30% or so.
There is two good articles over on TheInquirer about Intels road map and why they have to go the Increase the cache route for 2005. Worth a read. Part One and Part Two

This is a major overhaul of the aging nforce3 chipset.. Check it out.
Expect a flurry of new advances by the end of the year.
I am ready to buy a new Linux system and am pulling hair out trying to make the best choice. Due to Linux compatibility issues (and mixed experiences with nforce2), I cannot really consider nforce4 so it will be Via for me. Though Nvidia will likely get the nod for graphics.
The 90nm chips are a mixed bag at the moment.

The 4000+ isn't clocked any higher than the 3800+, it's just got a bigger cache. It's basically an FX-53; in fact, that's exactly what it is, sans the name. It would seem AMD is plateauing as well, but perhaps 90nm will get them out of the jam later on.
However, this is a wise move by AMD even if the rating isn't justified (hint: the benchmarks say it's not). Intel will never have a 4GHz CPU, and idiots who don't understand performance will see the 4000+ and want it because it breaks the 4000 barrier. It could backfire, but probably not, because even though 4000+ isn't justified, it's still faster than any of Intel's chips on 90% of applications.

All of the energy going into the processor is going to come out as heat. It's similar to what would happen if you put a lightbulb in a box, and then measured how much heat was being produced outside.
Some of the power going to the lightbulb makes waste heat directly, and some of it makes light. But since it's all closed up in a box, all of the light ends up making heat, too.
So yes, some of the power going into the processor does useful work. But from the point of view outside the processor at the heatsink, even the useful work creates heat.
How can heat sinks keep up? If you've seen the size of heat sinks that come with these processers, you'll understand.
I built an P4/LGA system for a guy last week. The heat sink that came standard with the CPU really impressed me - it's the kind of heat sink you would have expected to see hardcore overclockers paying $60 for two years ago. Very large and well-designed!
Times used to be when heat sinks weighed one or two ounces, and came with 40mm fans. Then came the 60mm fans. Now, 80mm fans and two-pound aren't at all uncommon, with some models using 92mm fans, and some weighing three pounds or more. Copper is being used for more and more of the heat sink. Better heat conduction, more surface area, and more air. It's not rocket science. : )
Plus, on the new P4's, the chips are able to run at much higher temperatures than previous generations. The greater temperature differential between the chip and the heat sink, the faster you can get the heat to conduct.
