Why even Dual Core? - Page 6

post #51 of 66
To vouch for the processing power of the C2D's look at things like -> Super Pi times. My P D805 @ 3.2ghz runs the 1m test on Pi around 26seconds, if I run the C2D at the same clock speed, I get around 16seconds. Even more.......Massive play games, such as Oblivion and Rise of Legends, really stress your system as a whole.....cpu/gpu/ram. Battle scenes would often lag'out my DualCore......I have had NO such problems w/ my 6700.....ever.
*Another factor that is often forgotten, is the fsb speed that a C2 runs at. The 1066mhz range for Intel fans has been limited through the past years to the 1337 few who could afford an Extreme series chip, which are often $900.00+ $$. Overall the increase in bandwidth is huge compared to 800mhz.....not to mention, now your OC starts, where your old 1 used to end.

You're getting 26secs in 1M SuperPI with a 3.2ghz 805? HOW?!?!

I'm getting 38secs with my 3.5ghz 805.

Ok.... Do realize one thing.

In order to upgrade to the E6300 Core 2 Duo Allandale, you'll need a new CPU (the E6300 of course), a new motherboard, and new RAM. That will cost at least like $475 or so, based on 1GB RAM ($600 if you want 2GB RAM).

Ok, having that said, I went from a dual core Opteron 165 that ran at 2.7GHz to an E6600, that I now have running at 3.4GHz. Even at stock 2.4GHz, the E6600 made minced meat out of the Opty.

Here is a review:
http://www.anandtech.com/cpuchipsets...spx?i=2795&p=8

The E6300 beats a dual core AMD X2 4600+ (which runs at 2.4GHz) in many of the benchmarks used by Anandtech. Thus, it easily beats yuor single core CPU in any application by a long shot (since I am sure the X2 4600+ destroys your CPU)


PS: I'd like to see a screeny also of that SuperPi time with the D805. That gotta be a record!!!

I'm getting 33 secs with my crappy Notebook. 1.86 GHz Single Core.

Check your running process's in the task manager. Knowing which ones you can eliminate for the purpose of running bench tests, will really improve your scores. Especially for super Pi times.

Even if you dont understand what are the factors that determin CPU speed. I would trust that a processor is not slow if 90% of the people on overclock.net are recommending it.
Everything tends to lean towards cpu architecture now, and the mhz war was over starting with the Athlon XP. Though a higher clocked cpu in the same class is faster.

Think of it like they used to think about cars. Before Core 2 Duo the fastest processors were like V-8's, easy to clock and work on and relatively good horsepower(processor speed). Now comes along the Core 2 Duo, a Twin Turbo charged V-6 that will eat the old school V-8s alive. When the Quad Cores come out they will be like Turbo Charged V-8's.

just a laymans explanation

And I'm talking only the benefits of gaming performance.
Its fine that it is fast in stuff like video editing, but I dont use that.
No, but you can make it work that way using task manager. Right click the process for program 1, and look for a setting other than end process, end process tree, and set priority. Set the core to 1 only. do the same for program 2, while setting the Core to 2.
Sorry for the vauge instructions, I only did this once on a school PC.

I'm waiting for the V12 from AMD.

I think its called set affinity, most of them are set to be able to run on either cores, and there are a couple processes that you can't set affinity for due to permissions.

It doesn't matter how many processes I run, I can never get even near 25secs.
And I have a 300mhz faster clock rate than you.
I still don't get it how you have such a good superpi result. That's a score similar to Allendale processors.
