CPU -which type you perfer?
    #5270164 -

I was just curious what people though of the different CPU's and their pros and cons.

you can also suit a cpu to do what ever job you have a need for it works both ways. get a cpu optized for what ever task. or optimize a cpu for the taskes that you need.

I disagree with you completely.

edit:
I'll assume desktop for this question. I'm going with AMD's 3800+ Athlon X2 right now because it's 64-bit and I can always upgrade to something much faster in the future.... I also assume it will work with Vista when it comes out... as well as the AMD64 port of Debian when I find the time to install it.

AMD for gaming and price

Intel for crunching @ home, seti, ect

I prefer a CPU with a single instruction as its instruction set.

I like the 939 opterons becouse they fit in dfi lanparty boards and overclock like mad and are cheap as fuck. AMDs pwn becouse they have on board memory controlers. This is why they are faster than intels.That is why a venice core 3500+ is 2.2ghz but the 3500 means that it will be equal to a intel 3.5ghz.It seems that intels need more ghz to get the same preformance as amd's. The 939 opterons are sometimes the same stepping as the fx chips. except with locked multi's. Opterons that have any stepping besides cabge seem to overclock to at least 2.8 on air cooling.

What is the difference between the different Intels and AMD's if they are rated at the same speed?

these are what make amds 31337

my opterpwn will do 2.8 at stock volts 28-32C idle 45C full load with air cooling. opteron s939 can be thought of like regular a64-fx chips. but usely cheaper but some times the prices are higher now that they are harder to get.

CPU Multiplier
All A64s are at least Half Locked. This means that you can set the CPU Multiplier Lower than
stock, but not Higher. This is a Good thing. Very rarely with A64's would you ever need to raise the CPU Multiplier over
the Factory setting. The exception to this are the FX chips, they are fully unlocked.

CPU Voltage
Most A64s have a default voltage of 1.4v to 1.6V. A64s are extremely efficient and usually can only take about 1.7v before they just start producing excess heat. I've run my Mobile up to 1.9v but found it did NOT help my overclocks and simply caused the CPU to produce enormous amounts of heat. These are NOT XP-M chips! While I doubt that running voltages between 1.75 and 1.9 will cause any permanent damage, it certainly has not shown to be beneficial in any tests I?ve seen so far.

HTT Frequency
A64s don?t use a traditional Front system Bus. Instead they use a HyperTransport. I can only assume its abbreviated "HTT" to differentiate between Intel?s "HT" and Hyper-Threading Technology. They are VERY different.

The HyperTransport is what controls the base frequency for communications and CPU speed in our A64 System.
The CPU Speed is controlled by the HTT Multiplied by the CPU Multiplier, The HyperTransport or Memory controller is controlled by the HTT Multiplied by the HTT Multiplier, and Memory speed is controlled by the HTT Frequency, Multiplied by the CPU Multiplier and then DIVIDED by the Memory Divider. That?s a bit confusing for most folks. And it took me a while to grasp the concept as well.

HTT Multiplier
Most AMD Motherboards are designed to handle an 800-1000 MHz Hyper Transport bus. Factory Default on 754 CPUs is 800 MHz (A 4X Multiplier) and 1Ghz (5x) on 939 CPU's this is a Critical part of Overclocking an A64 to the Max. Pushing the HyperTransport past 1Ghz can cause all kinds of system instability that is commonly misconceived as "I maxed out my CPU" or "My Ram is holding me back"

Memory Divider
This is one of the most Confusing aspects of A64 Overclocking. There is ALWAYS a memory divider.
Setting the Memory to 1:1 means that the HTT bus is multiplied by the CPU Multiplier and then Divided by the CPU Multiplier to set the Memory speed. This means that it is OK to run your Memory at its peak efficiency and still go higher with your HTT bus if your CPU can take it. Take note that I said its "OK" not advisable. There are still sufficient tests out there showing that running a 1:1 ratio will garner you the best overall performance. I plan on adding a few test results in the next week or so showing the difference in performance using a higher memory divider than CPU Multiplier.

Since A64's use an On chip memory controller, the Ratio must be calculated a bit differently than old. 5:6 is NOT always 5:6. See that chart at the end of this post for a prety darn close representation of what each divieder is doing. Thanks to Oskar from DFI for the chart.
