Processor Clasification What's the difference between a Pentium 4, a Pentium M and a Pentium D? How can I tell a Celeron D from a Celeron M? In fact, which Pentium processors are 64-Bit? What on earth is going on with the markings for new Intel chips? For example, what is a Pentium 4 530's clock and bus speed? Was it down to bad marketing people, or was it done on purpose, to hide the fact that CPU speeds aren't increasing? Please read this article: http://www.tomshardware.com/2005/10/25/pentium/ Things were a lot simpler when we used typewriters....... EDIT: PLEASE MOVE THIS TREAD TO WAR ZONE!
They're doing what AMD has successfully done: using performance ratings instead of clock speeds to advertise the CPU. Intel has hit a brick wall in processor speeds, and that was where they were winning...for quite awhile. However, AMD's strategy of more work per clock cycle has given them a major boost. Today, if a CPU, say Pentium M, has an 'M' after it, it's a pretty good indicator that it's been designed for mobile applications, i.e. laptops. Lower power usage and heat output (as a result of lower power) are the major point of intrest. Intel uses a slightly different socket for their mobile chips, but AMD does not. Overclockers like mobile CPU's for the low heat output, which generally leads to some very nice overclocks with stock cooling. On the flip-side, mobile CPU's aren't as cheap as a standard desktop CPU. Multi-cores and increasing the work per clock cycle are the new way of getting more power. As stated before, Intel has abandoned trying to hit super high clock speeds. They ran into trouble trying to get a stable 4GHz CPU...by which I mean stable with stock cooling and stock voltages. The Pentium D takes the place of the Pentium 4, and is LGA775 only. The 300, 500, and 800 Pentium4/D CPU's have differences regarding HyperThreading and dual-cores. I haven't paid attention to the differences, but the 800 series CPU (I believe) have both dual core and hyper-threading. I'm not sure on the Pentiums these days, as I really haven't been paying attention. The higher the number in a series, the faster it is. The higher the series number is, the more features the CPU has. The Pentium D is available in the LGA775 format only, where as the P4 can be found in PGA Socket 423, mPGA Socket 478, or LGA Socket 775. PGA=pin grid array, mPGA=micro pin grid array, LGA=land grid array (the pins are in the socket, not on the CPU).
Wouldn't it have just been easier to call it the Pentium 5, or is it based too much on the Pentium 4? BTW, when & why was the 478 socket retired? I bought a new computer last year with a socket 478. I was under the impression this socket was going to be the last for the Pentium 4?
I've just read that Intel are finally retiring the Pentium brand name! ! They will be fased out first on mobile products, then eventually desktops as well! Here is the news: http://news.com.com/Bidding+adieu+to+Pentium+M/2100-1006_3-6004731.html?tag=nefd.lede
For the Pentium 4, yes, Socket 478 is the last. LGA775 P4's were there mostly because there needed to be some CPU's for the new interface. The Prescott core wasn't designed with 478 in mind, which is where LGA775 came into play. LGA775 was designed for Prescott and future Pentium brand chips (until Intel changes the socket at some point---and they will). I can't recall why Intel went with the Pentium D in lieu of the Pentium 5 branding. I suspect it was due to the shift toward dual-cores instead of pure clock speed, but this is just my personal speculation.
Is that what the 'D' in Pentium D stands for, Dual-core? :x: How did I miss that one..... But wait, there is also a Celeron D. Are they dual-core? As you can see, I am really living in the dark ages!
celeron d's are not dual core, the only difference between celeron d, and celeron s is that celeron d's run on prescott cores i think (celeron d's are like a pentium 4 prescot with its wings clipped)
obviously not, as i said, there is no celeron dual cores. celern d is just the newest type of celeron cpu for desktop boards i think. the d is just another revision i think, like with ad 64's, instead of numbers or letters, they have place names, like venice, san diego, newcasttle etc...
Actually Intel uses codenames like AMD does, but it seems that AMD's cores are generally getting more attention. At this point, Intel does not have a dual-core Celeron, but I think they added the D onto the Celeron naming scheme to keep it attached as a Pentium derivative.
