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.

Search for 939 on newegg.com folks, you will be pleasantly surprised! Now if we could just find a motherboard...I had been hopping this launch would bring the 754 prices down a bit to, say, $220 for a 3200 and $350 for a 3400, but it doesn't seem like that's going to happen quite yet what with 939 starting out at $500 for the 3500 and $700 for the 3800... *sigh* ... more waiting... perhaps prices will come down by the time true PCIe motherboards are availeable.

"Everything here is graphics card limited even at 1024x768, but perhaps in the near future when we upgrade the video card we use in CPU and motherboard tests..." i have said this at xbit site and I say it here again!What about lowering games resolution and details it may help! There is a detail level in almost every game, it may help. You are testing a processor not the video card! I don't want benches in a processor review that limit the differences between processors.
fx53 35 fps vs xp3000+ 34fps, what a difference!

#22 while I certainly agree these new prices are too high I dont agree with the wholesale gutting of prices that you're recommending. AMD deserves some decent margins, they shouldnt have to give their product away all the time. Thats unhealthy business and has really hurt amd in the past. I want a healthy amd and for that they are going to need some fatter margins on some sku's.RyanVM - Tuesday, June 1, 2004 - link
Found a typo on page 13: "Winstones hare usually very static..." should be "Winstones are usually very static..."XRaider - Tuesday, June 1, 2004 - link
What the heat issues with these newer AMD cpu's? I believe I read on that French site that the new AMD's are putting out alot of thermal wattage! 100+ Can anyone confirm this? I believe the P4 3.4 puts out around 102 - 104 watts! That's alot.AtaStrumf - Tuesday, June 1, 2004 - link
I found a couple of typos if anyone would care to correct them:p.13
Workstation performance is more sensitive to memory bandwidth, and we do see a wider range in variation among the --3.2GHz-- (THAT WOULD BE 2,2GHz) processors in SPECviewperf.
The pattern was the generally the same fastest to slowest of 939-949-754 (THAT WOULD BE 939-940-754)
p.14
Since we have found the performance of the Dual-Channel Socket 940 and the Single-Channel 754 to be close when hey (THEY)ran...
Anyway these new S939s suck a$$. Well actually their prices do. Here's what I suggest: retire Athlon XP socket A, introduce it as Socket 754 but only higher models, price 20% up, bring S754 down 33% and S939 down 50%, retire FXs. These prices now are insane.
AMD are you listening? Of course not.

"i'll be getting a Dual Channel for sure when the arrive. Pair that with a nice new X800 XT from ATI and i'll be sitting pretty with the flexibility of upgrading for awhile"Horses for courses I guess...I'll be getting one too, but I think I'm going nvidia because they appear to have a better handle on 64bit drivers...
JMHO

Sure would be nice if they released something more along the lines of a 3000-3300+ for 939 this year. Maybe then my brother can finally be nice and justified with an upgrade without having to spend a lot.Icewind - Tuesday, June 1, 2004 - link
Hmmm, well i'll be getting a Dual Channel for sure when the arrive. Pair that with a nice new X800 XT from ATI and i'll be sitting pretty with the flexibility of upgrading for awhile.Thanks again AMD, im anxious to get out of this P4 setup I have now.
