[AMD] Exposing the Phantom x86 Bottleneck - Page 2

With Bulldozer's architecture wielding more integral processors, it should scale very well.
True, it depends on the server workload. Magny Cours actually beats Xeon overall in data mining and HPC: http://www.anandtech.com/show/2978/a...-s-6-core-xeon

Hi Relevant,

True but then ocing and all is so much fun! Kind of like drag racing nobody needs a 1000hp car but boy are they fun to drive!
Now what I got out of the article is that if you want straight up numbers do intel, if you want bewtter integration go with amd. Since a computer, server, workstation or terminal, is the sum total of its parts amd is looking to gain the edge in a synergistic computer environment in which all the compnents to benefit from the core processor's strength. Personally I don't see this as being much different than Intel's emphasis on multi threading (hyperthreading). Both are trying to utilize the cpu down time to incrementaly increase over all system performance. Hyperthreading was successful at this. Now let's see how AMD answers that when we finally see the real data on BD.

As an afterthought I also recall AMD saying server workloads were something like 90% integral. Which would also place the bulldozer architecture at a huge advantage. (Since it would be ditching all that extra floating point power that sitting idle.)

So what if they render video better? I offload it to the GPU's anyway.

I'm interested in ONE thing...GAMING!

All I want to know is will the next generation of AMD CPU's have enough grunt to remove the sometimes dreadful bottleneck my Phenom 2 places on my 5850's?

If I blow up a car in Crysis will the framerate drop down to the teens until the CPU catches back up...

Interesting, I would think HPC workloads would most be FP and DP-FP?

Your 4.2GHz Phenom II should not be bottlenecking your GPU.... your CPU usage on a 2-4 cores are at 100% in game?

I agree with Duckie. You shouldn't see any bottleneck. Especially with ATI cards on a Phenom II.

You can probably attribute your dip in framerates to crossfire and not the CPU.

Crysis, Warhead, STALKER series......80% of the games I play are only dual threaded and while for the most part performance is really good. When the on screen action heats up or things explode the frames drop down below 30, sometimes way below 30...

It's the CPU as it only happens when things get heated, Or when heavy CPU work loads are involved..

More "Oh my noez the framerates dropped so it must be my cpu!". Why? Why does one always come to this conclusion???

When things get heated, your GPUs get loaded too....


How do you know how heavily the CPU is loaded? Like I said, do individual cores hit 100% load during these instances?
