<div class="IPBDescription">with these processors</div> I was looking through newegg at some AMD processors and seeing what the price of them and how fast some were and i found this. This processor is the one i have.

it is a AMD 64 3200+ 754 in at 2.2ghz. now i found this.

it is the same AMD 64 3200+ processor but with a 939 socket but it is clocked at just 2.0 ghz. why is it that a 754 is clocked faster than a 939 pin?

    Different cores probably. The first is a Newcastle 130nm while the second is a Winchester 90nm.

    939 pins-> 128-bit memory interface (aka dual channel). It's estimated most modern processors spend as much as 80% of their time rolling their thumbs and trying to find something to pass the time while they are waiting for the RAM. 128-bit memory interface helps a little but since it's mostly a latency thing it isn't that huge an advantage.

    Clock speed is a very minor component in performance in general unless architectures are similar. Look at the cell processor from Sony, it's a very agressive and different architecture, it is rumored to use a g5 or similar with a bunch of 8-16 attached simpler processors that can be linked up as a stream processor architecture on the fly if wanted or be allocated to various tasks, and have extremely fast rambus memory technology(I know some of you hate this IP company, but really, good tech is good tech no matter how much you hate those who made it possible...). If the processor anywhere near delivers on the performance promised a single cell processor will for many parallellizable tasks(DSP, FFT, practically anything to do with graphics, collision detection and the newtonian style physics you tend to find in games are obvious targets) be an order of magnitude faster than anything on the single processor PC market and the ps3 is rumored to have 4 of them.

    edit: the e0 stepping is rumored to be comming out soon and that will run even cooler than the winchester and include SSE3 support. It is also rumored to include an updated memory controller that will allow all 4 RAM slots to be populated with double sided RAM without dropping to a 333 MHz FSB configuration.

    939 pins is alot of soldering ^_^

    No wonder they cost so much!
