You have to forgive Ackmed... He has no clue why he is in this thread and for that matter, he has no clue what this thread was trying to prove.
Ackmed, let me explain this in simple terms. If we were to test at the highest resolution, then the GPU becomes limited and the CPU has to wait to feed it... Now, when we run a lower resolution, we become CPU limited and at this point the GPU is waiting for the CPU... Now, naturally, since this thread is about Dual Core peformance, we would want to test it in a CPU limited scenario, and that is 640 X 480.
Got it? Or should I simplify this even more for you?
Oh, I myself like dual anything, but the dual-core 820 is more expensive than a single core at a higher GHz. And not many programs are multi-threaded, etc.
I sure can, especially to someone who is rude is nearly every thread. This is the same person who calls everyone ignorant and so on... Basically, I have no problem telling you how it is. You are either his bunk buddy, or you have no idea what you just commented on. Perhaps you should turn up in a few more threads before you make a generalized statement like that. I definitely can be a jerk, but only if you deserve it... Do you deserve it?
What good does testing 1024x768 with a crappy synthetic benchmark do? If it doesnt increase frames in games, its worthless. (to me)
I didnt "suppose" your benches were ran at 640x480, read again. Someone quoted me, and gave some results with that.
Trying to prove? Who plays games at 1024x768 with a modern card and X2? Show of hands anyone?
Do the extra frames at such a low res matter, if it doesnt increase the frames at a higher res that people play at? Nope.
:roll: Its amazing how easy Video turns into a flame fest. And all it started over was benchmarking.........
Again I would doubt that you will see an increase in CPU starved Senarios. From what I have read it is more of a offloading of some computations (vertex is one rumor) to the second CPU. While great for improving performance now i am guessing it will be more of a hinderence once games actually use the Second core. To me it is a Hack, a good hack, a hack I would use, but a hack non the less.

Oh, ok. You really don't have a clue. If the CPU bottleneck is "moved up" so to speak.
For example. If a CPU bottleneck ends at say 1280x1024 in hypothetical game A, dont you think that this will move the CPU bottleneck UP one res "possibly"? 640x480 is just a sure fire way to see if the new driver IN FACT DOES UTILIZE MORE OF A DUAL CPU SYSTEM (sorry hit caps lock). This means that the point where CPU bottleneck becomes GPU bottleneck is Moved up. Meaning if people cant get any faster fps at 1280x1024 because of a CPU bottleneck, maybe they can now due to 2 cores being utilized more.
What do you think?

I did a few more tests on the dual core usage with my cpu at the factory default of 2ghz.
It seems that the drivers core usage is the same whether the cpu core is 2ghz or 2.6ghz. I was thinking that maybe it would use the 2nd core alittle more if the speed was slower. But that does not seem to be the case.
Whether the cpu is 2ghz or 2.6ghz the drivers still use about the same 15%-20% of the 2nd core. Just thought it was worth checking out

I think ackmed actually has a point. I mean the german site we all saw the first time around got some great increases in FPS in games. So maybe these drivers takes the load off the card in some way... by maybe making the other cpu calculate things the gpu would otherwise calculate ... that was just an example but i'm sure ill get flamed for saying such a "STUPID" thing... but that's how these forums are hehe.
So yea some gameplay FPS increases would be cool.

In fact that's exactly what I heard. The drivers offload vertex processing to the unused second core.
Maybe you are miss remember something, I on two or three accasions mentioned that (in this thread). All Ackmed has done is jumped up and down about useless benchmarks at 640x480 are.
Add the "Threads" column to Task Manager and I think you'll find that all Win32 apps are multi-threaded.
I think what you meant to say is that very few apps divide their processing into more than one worker thread, thus they end up with a single thread eating 100% of one core, rather than two threads using both cores.
All this assumes the user is only interested in running a single CPU intensive task.
Good ol' Performance Monitor (part of NT since the beginning) is a must-use tool. And yes, it can easily dump the log to a file that you can investigate later.
What I am curious about is if in fact the drivers do offload the vertex processing or other GPU
chores off to the second core, will other vid cards besides the 7800 series see a similar performance gain in fps? Especially say a 6600GT(which I own and would really lean me towards the X2 as my next CPU purchase). Also wondering what percentage of these driver gains are due to 7800 tweaks versus more dual core usage....Probably hard to pin that down.
