AMD Athlon 64 3800+ and FX-53: The First 939 CPUs

SYSmark 2004
When running at 2.4GHz, the FX architecture drives past everything else. We are seeing that the 939 pin FX53 is a little bit slower than the 940 pin version. This is not the norm for our benchmarks, as we will see, but the socket 940 solutions do manage to pull slightly ahead in some tests. Our theory on this is that the build quality of a 940 board is a little higher as it is intended to be a workstation or server platform. And, of course, we are using the very high performance SK8V board as our 940 platform. The 3500+ is outperforming the 3400+ as expected.
The content creation suite of SYSmark 2004 shows that the 3800+ and FX-53 939 parts are very similar in performance, meaning that cache size has little impact on this benchmark (as the only difference between those two processors is 512kB of cache).
We see the same trends in Office productivity that we saw in the content creation suite, with the exception of the fact that the FX-53 pulls a little further ahead of the 3800+ (showing that cache size is a little more important in this test.

That earlier french review couldnt get 4 DS sticks to work at DDR400:http://www.x86-secret.com/articles/cpu/s939/s939-3...
Still, I'd sooner have the dual bank memory than the extra cache. But if it is $800 and $600 then the Skt754s become good buys.

#6 - With memory prices where they're at now, the more dimms the better.For example, if you were to be building a system right now, you'd be hard pressed to justify getting anything more than 1GB (2X512). This fills up 2 slots already, thus only allowing 1 free slot for upgrade in the future. If you were to upgrade with another 512 stick, you'd have 1.5GB, but all your spots filled. If you want this system to last a while, that might just not do.
I say that 3 is definately the minimum you'd ever want, and wanting 4 is definately not out of the question.

#5 - Is running four unbuffered DIMMs really that necessary? I mean... I haven't ever had more than two DIMMs since my 486, which technically didn't have any DIMMs... but it had 4 one MB SIMMs.mechBgon - Tuesday, June 1, 2004 - link
One potential benefit to the Socket939 platform is that it should open the door to running four unbuffered DDR400 DIMMs.JGF - Tuesday, June 1, 2004 - link
Hmm, now Toms is reporting the $700US+ price of the 3800+ as well. This had better not be true. Roughly $50 seperating the FX line and the 'regular joe' A64 line?? Please AMD, tell me this isnt right...Jeff7181 - Tuesday, June 1, 2004 - link
Well well well... looks like socket 939 isn't really worth waiting for, especially if it's priced a lot higher than socket 754. Socket 754, here I come :)JGF - Tuesday, June 1, 2004 - link
Good read. Couple of disappointments (though not neccessarily wesley's fault):1. Pricing/availability - supplies of 939 parts are rumored to be VERY constrained and some quarters are even uttering the dreaded p-phrase (paper launch). Also early listings for the 3800+ are placing it at an astronomical $700US+ which is obviously bunk. SAtill we are without any official statement regarding price and availability.
2. No 3700+ scores or even a word with what is happening there. With the rumored constraints on 939 and the fact that PCI-E from VIA or nvidia wont be around until late summer, I'm actually seriously looking into a 3700+ 754 system. When will we get info?!?

hmmm, 30 mins after the nda ended. Yall need to get on the ball.
