Audio/Video Encoding
MusicMatch Jukebox 7.10
DivX 5.2.1 with AutoGK
Armed with DivX 5.2.1 and the AutoGK front end for Gordian Knot, we took all of the processors to task at encoding a chapter out of Pirates of the Caribbean. We set AutoGK to give us 75% quality of the original DVD rip and did not encode audio.
The Sempron's encoding performance is pretty competitive, but the Celeron D still pulls ahead.
XviD 5 with AutoGK
Another very popular codec is the XviD codec, and so, we measured encoding performance using it instead of DivX for this next test. The rest of the variables remained the same as the DivX test.
Windows Media Encoder 9
To finish up our look at Video Encoding performance, we have two tests both involving Windows Media Encoder 9. The first test is WorldBench 5's WMV9 encoding test.
Next, we have our own home-brewed HD encoding test:

#28 overclockingoodnessMy point exactly!!! Someone with an AXP and a 6600GT looks at those charts and thinks: "Holy crap, I really gotta get me a S939 Athlon 3200", when in reality that would be a waste of his money, becasue his GPU would be the bottleneck and a S939 chip would not be able to do $h!t for him. That's why I think, it is important to run CPU game tests with a comparible GPU, otherwise the picture is seriously distorted!
The best thing to do, would be to run both sets of tests, because running just high end GPU tests is not telling the whole story. A VERY IMPORTANT PART is missing!
Because of tests like this, I don't really know how much of a bottleneck my Athlon 3200+ S754 is or is not, when coupled with my 6600GT. Should I primarily invest in a new CPU or a new GPU? Only if I get a new high end GPU, can I actually use tests like this to tell me if I should also get a new CPU or is that just a waste of my money?
GPU tests make this same mistake, by eliminating the CPU bottleneck, by using FX-55 and co. The problem is, that by doing so, they venture in unreal territory, with, for the most part, unrealistic CPU/GPU combos. Great for theory, not so great for practice!

I mean DUAL CORE READY.nserra - Tuesday, April 19, 2005 - link
I think this review lacks Athlon 64 with socket 754. Unless Athlon 64 with that socket is dead?Even so is not right comparing a socket 939 with a socket 754 CPU.
AMD is doing great with this new CPUs, too bad they have a bad markting machine.
Right now if INTEL WAS AMD we were already having a campain saying DUAL CORE COMPATIBLE on socket 939 boards. But no ....

can any reviewer give a guide as to which tests included SSE3 optimisations?This was not stated in the review.
Until the newer stepping of A64, many will not have SSE3, and so, in some media encoding tests you may have been able to show a difference between the A64 and the Semperon (in the semperon's favour).
I'm running an A64 3000 on S939, with no SSE3 support.

Tujan: The Lightscape benchmark comes as a portion of SPECviewperf 8.1. It is not a standalone application.Kristopher

This reminds me a little of a few years back when a thunderbird cost barley more than a spitfire / morgan. made the duron have no market place. AMD should keep the sempron much more crippled than the a64, to give the sempron its market and protect high end a64 chips sales / status. either that or make the lower number a64's unavalible sooner, and replace them with sempys at higer numbers.karlos

Cool & Quiet only works for the Sempron 3000+ or higher. The socket 754 2600+ and 2800+ do not support it.cryptonomicon - Monday, April 18, 2005 - link
Man I wish there was an exciting TWIST In this article, oh well. Just looks like AMD looked to cut costs in the latest sempron and produce a more power/heat efficent processor, not much fancy :(Avalon - Monday, April 18, 2005 - link

Anybody Have a Link to the Program used here. To browse:"""Lightscape Viewset (light-07)
"The light-07 viewset was created from traces of the graphics workload generated by the Lightscape Visualization System from Discreet Logic. Lightscape combines proprietary radiosity algorithms with a physically based lighting interface.
The most significant feature of Lightscape is its ability to simulate global illumination effects accurately by precalculating the diffuse energy distribution in an environment and storing the lighting distribution as part of the 3D model. """....
I looked at AutoDesk but 'Lightscape,is no longer supported/obsolete. Cant be the same program. thanks.
