AMD's X2 A Failure Over At Tom's

"AMD's X2 A Failure Over At Tom's"

Tom's Hardware guide is doing a live test of the latest AMD X2 4800+ vs Intel?s 840EE CPU based systems. What is showing is that the AMD multitasking is faulty. The AMD X2 CPU's push aside tasks that they find difficult and result in low priority.

We all know AMD CPU's are poor at floating point operations and also heavy work like Divx encoding but in the test it's showing that in one of the tasks of doing a Divx encoding loop, the AMD is struggling to equally dedicate CPU operations for the task.

I personally think the problem is at the stage where machine code instruction are prioritised before thread computation. It seems the AMD is congesting the thread and allowing other threads to get more attention.

This is shocking news for AMD's dual core project as it indicates they are poor performers for balancing task load. Also there are issues with business use reliability regarding AMD's X2 fan running at crazy speeds of 6000RPM.

Wow, X2 bashing at Tom's, whodathunkit?

I don't know anything about the internals of OS scheduling and load balancing, but if someone thinks that 6000RPM fans are going to be such a big issue, one needs to pull one's head out of one's anus and realize that one is not forced to use such an insane cooling device.

Nice troll thread. The P4 has HT which does give it an advantage when running four CPU-heavy tasks at once instead of 2 or 3. If you must RAR warez while encoding MP3s and divx and playing Far Cry at 1600x1200 then I guess you want to buy intel since X2 seems to top out at only 3 CPU-heavy tasks.

Of course for gaming P4s are a lousy choice, but hey if you spend all day encoding 3 things at once while you game then yay intel.

I would say that the Intel systems 3 reboots (one recent and not recorded) is more of a problem. Its only been about 2 days, right?

So the AMD X2 is great for 3 tasks and anything over, it refuses to do? Sorry but there is a clear fault happening since the start of the test.

I don't understand THG website. It looks like they don't give any benches or draw any conclusions.

Rebooting isn't an issue other than if it's repetitive. We all know games like Farcry crash once in a while, and especially there will be crashing on SLI drivers etc. The AMD system was the first to fail and rebooted, so this factor isnt' important. Crashing isn't the concern as of yet.

The topic we are discussing is AMD?s X2 failure to multitask.

If you can't take negatives in previews then you are undermining your quality expectations when purchasing.

You're contradicting yourself (Intel system crashes 3 times, but it's not a problem if it's not "repetitive"), and you post a blatantly trollish thread and bitch when people call you on it. You, obviously, love to point out any negatives you can squeeze out about the X2, but get really uncomfortable when anybody brings up Intel's weak points.

anand previews came out quite positive for the X2.

Here's the previous intel troll thread from porkster!

What's happened to BTX and PCIexpress. I hope AMD64 isn't balls'n the market up again. God I hate AMD.

link sounds like objective criticism to me!

 

[Bar81]

Well, at least he's subtle

I just looked at the chart, and in 3 of those 4 tests the X2 creams the dual core P4, including a CD encoding task, I'd say wining 3 out of 4 tests that are constantly being looped is better than only being good at one test that doesn't look like an issue to me and we all know the P4 is better at Divix encoding esp. since most of the divix tests over at toms are optimised for the P4.

The only reason the intel can do that is it has hyperthreading, so it shows up as 4 CPU's to the windows scheduler. Because it shows up as 4 threads, the CPU can run faster in some scenarios. But, it also runs significantly slower in other scenarios because the windows scheduler doesn't know how to properly deal with 4 threads. So, if you ask me, its the P4 XE thats is a failure, because its "feature" often cuts its performance in half.

Plus the fact the P4 has crashed 300% more than the X2

Well there is a tiny point buried in the trollish bile, that while the X2 is good at time-slicing 3 heavy loads, it doesn't seem to give any time slice to a fourth (the divx encoding).

Of course the test was probably designed that way by Toms to make the X2 look bad. If there were 5 (or maybe 6) high-load tasks the P4 would likely ignore the last task just exactly like the X2 ignores the fourth task in this test.

(And if there were 3 heavy load tasks we'd see a real comparison of work done, but Toms might not want that.)

Where are you getting this nonsense about "struggling to equally dedicate cpu operations"? The X2 is clearly outperforming the 840 EE in three out of four tests as seen here.

I did notice a very large difference in the fan RPMs however.

Note to self: Get aftermarket cooling solution when you upgrade to dual core.

You're missing the troll's overhyped point, that the X2 is devoting essentially NO CPU time to the divx task, it is being starved for cycles.

If Windows task scheduler worked better, or X2 supported hyperthreading, that fourth task would be charting much, much closer to the P4 performance, while the other 3 tasks would not be so far ahead of the P4.

But again, this is not the big deal the troll wants to make it into, the P4 has a limit on how many CPU-and-I/O heavy tasks it can juggle at once too, that number is just a little higher (and Toms was probably careful not to find that limit)

Answer this, the stress test has been running for approx 2 days (actually closer to 42 hours) IF the Intell system had been running the whole time it should be able to encode 1 minute of DivX for in every 3.5 actual minutes (42 hours x 60 minutes in an hour = 2520 minutes divided by 720 minutes of encoded video = 3.5 minutes). The problem is the Intel machine was not processing for 9 of those hours so it should be even faster (42 hours - 9 hours x 60 minutes in an hour = 1980 minutes divided by 720 minutes of encoded video = 2.75 minutes) but I have been watching it sine before porkster post at 12:36 and it is now 1:40 and there has been no change in either the Intel or AMD DivX numbers. If Intel was actually going that fast I should have seen an increase of at least 15 to 20 minutes of encoding for the Intel system. No matter how you look at this something must be wrong with the DivX score, so it doesn't make you look to bright using this as proof.

BTW Intel at 720, AMD at 30
