AMD's Socket 939, Athlon 64 FX-54 amd 64 3800+
BudKnight writes "It looks like AMD is launching four new desktop processors, a new core, and
a new socket infrastructure today.
HotHardware has tested AMD's two new
flagship processors, the Athlon 64 FX-53 and the Athlon 64 3800+. The new
FX-53 no longer needs registered memory to function and the 3800+ has only 512K
of cache, but it gets an upgraded 128-bit memory controller. The usual
suspects also have reviews posted as well -

AcesHardware found that disabling the 2T memory timing in the BIOS improved S939 performence by over 10%. The only limitation with this is one DIMM per memory channel.
A lot of reviews you read today will not be using this, and the results will therefore be significantly lower than what is possible.
SGI's Origin supercomputer's are essentially clusters of Itanium 2 boxes in a NUMA architecture...And they're still supporting them.

Assuming the software would run faster in 64-bit mode, which isn't necessarily true.
Most likely it will - though not necessarily through the use of 64-bit math. The AMD64 adds several additional registers, and that alone can make for a huge performance boost when a complier knows how to use them...
As I understand it, you can't build a 4-layer motherboard with socket 940 (you have to use 6 layers). By changing the pin layout for socket 939, it is now possible to use 4 layers. This should reduce the cost of motherboards.

What?
Have you been hibernating past few months?
Prescotts with Intel's version of x86-64 are coming out by early autumn. MS delaying the OS is partly because they don't want to piss Intel off. They also want to ensure the thing works perfectly on both versions, and while they are largerly compatible, there are couple of small differences.
Be aware that this is a benchmark for jvm's, and has little to do with machine performance. According to the benchmarks results page. A PIV 3.0 GHz computer can score anywhere between 228 and 557. This benchark also seems biased towards 32bit machines. One thing that is essential for any test is for it to at least be internally reliable.
As introduced with our Athlon 64 article, we are looking at compile times for the Quake III Arena source code. In running this test, we compiled the source for both Q3A and Q3TA in both debug and release modes using the Batch Build feature of Visual C++ 6.0. The build was run three consecutive times for each processor (in order to try to reduce file read time impact), and we used the third compile time.
Note to self: Stop putting jokes in my insightful comments so I can get something other than +1 Funny!
740 was not released in the last year, it has been around forever as the Athlon XP socket.
940 is for the high end. You can't put a Xeon in a P4 board. It's not going anywhere.
754 was a stepping stone to 939 which is better and cheaper. Intel did the exact same thing when the P4 came out and they went from Williamette to Northwood (socket 423 to 478). It may be inconvenient to people who didn't do their research - socket 939 was known to be coming from day one - but it's not unreasonable or unprecedented. Also, Socket 754 will be supported for at least another year so it's not like they are totally abandoning it today. The 3700+ which is very comprable to the 3800+ is on 754.

Out of curiosity, I tied these scores to CPU prices as listed at http://www.pricewatch.com/:
CPU SCORE US$
Athlon64 3200 64: 523.70 $255
Athlon XP2700: 467.15 $ 80
Athlon64 3200 32: 449.07 $255
Athlon XP2600: 448.42 $ 71
Pentium4 3.0GHz: 387.57 $203
Athlon 1400: 305.26 $ 97
AMD Athlon 950: 209.51 $ 69
Sparc 500MHz: 52.21 ???
Sparc 440MHz: 51.89 ???
Sure, I've done this.
1. Buy whichever AMD64 processor you like.
2. Buy a motherboard that supports that processor.
3. Buy all the other parts (RAM, hard disk, graphics card, etc.).
4. Put it together.
5. Install Fedora Core 2.
Personally I used an Athlon 64 FX-51, an ASUS SK8N, Corsair low-latency RAM, and a Radeon 9800 Pro (if you're not playing games, get a cheaper video card).
