Pentium D and core duo

[benjamat]

can anyone explain to me the difference between pentium D and the newer core duo processors.

Thank you.

In a nutshell, a Core 2 Duo is more than twice as fast as a Pentium D, when both are at the same speed.

Pentium D = Pentium 4 core architecture

versus

Core Duo = Pentium-M (Pentium 3 derivative core) architecture.

Depends on the level of detail you want.

The Pentium D is based on the Netburst microarchitechture. It's essentially two Pentium 4s.

The Core Duo is based on a modified form of the P6 microarchitecture. It's essentially a revised Pentium M. And the Pentium M is essentially a revised Pentium III, which is essentially a Pentium II, which is very similar to the Pentium Pro (that is, the P6). At a given clock speed, a Core Duo will outperform a Pentium D.

The Core 2 Duo (which I'm guessing you're refering to) is based on the Core microarchitecture. It's mostly similar to the Core Duo, but with aspects of Netburst folded in. At a given clock speed, a Core 2 Duo will outperform a Core Duo by a bit, and a Pentium D by considerably more.

If you really want the nitty-gritty of the differences, there's an Ars article I could hunt down.

Pentium-D= netburst architecture. Low IPC high clock speed design. Lacking in performance compared to AMD's X2 and Core 2 duo

Core duo=pentium-m based dual core. low power, low clock speed, higher IPC design. Pretty close to performance of AMD X2 clock for clock. Designed for laptops.

Core 2 duo=core architecuture. Higher yet IPC design. Higher stock clock speeds than Core Duo. Has the features of netburst chips such as 64bit, virtualization, SSE3. Also has improved SSE can do 128bit SSE in a single operation, compared to needing 2 for X2/Penitium-D/Core duo. Fastest clock for clock of current CPU's. 2.4ghz core 2 duo performs similarly to 2.8ghz X2. Faster than any pentium-d.

Thank you for your replies, it seems I made a big mistake in upgrading my p4 3.2 to a 3.0 pentium D. I was taken in by the hype about dual core.

Actually, that's a descent upgrade considering you can get some cash back on the 3.2Ghz CPU you replaced. Programs and games that are multithreaded will run much faster and multitasking and general system snapiness should improve as well.

Now if you have a motherboard that supports Core 2 Duo and you went with a 3.0Ghz Pentium D instead of a Core 2 Duo, then it was a bad decision.

I bought a 2.8 Pentium D to replace a Socket A Sempron chip...:thumbsup::thumbsup::thumbsup::thumbsup::thumbsup: (I'm all thumbs...lol)
I couldn't afford Core 2 Duo...
