Muzosi, Re: "point out the fact that what intel advertises as a 2.2 p4 is a 133mhz/2.2ghz/4.4ghz chip (at least)." What?!? I see where you might be getting 4.4GHz from the double pumped ALUs, but where the heck does 133MHz come from? Re: "in this context, one has to consider whether a 2.2g p4 is any faster than a 1.6g athlon." It is. Countless benchmarks verify that this is so. wbmw

Muzosi, if AMD wants to break down the notion that clock speed equals performance, they would make an honest effort in pushing their True Performance Initiative. Instead, AMD would rather push the notion that "QuantiSpeed" equals performance. Tenchusatsu

"but point out the fact that what intel advertises as a 2.2 p4 is a 133mhz/2.2ghz/4.4ghz chip (at least)." This is somewhat inaccurate. First, a significant portion of the chip - caches - runs at 1.1G, because it is simply the physical limit of their SRAM cells for the given technology. Second, the ALU appears to be only 16-bit-wide, Message 17045696 so the 4.4G is quite a stretch due to half of the bandwidth. Third, there are indications (discussed at length by kapkan4u here) that another third of the chip is also running at half of marketing frequency - decoders for example. Lastly, to be honest, the bus interface unit must run not at 133MHz but rather at 533 or 400, to handle the quad-pumped data. So, IMHO, the P4 formula mix should look like: 2HGz P4 = 10%(@533)70%(@1000)15%(@2000)1%(@2000*2/2) - Ali
