Bring Out the Dual Cores

Cool Tech

June 2, 2005 01:01 PM PST

With AMD's new release of its dual core line it's time to start the frenzy of reviews and comparisions.

NeoSeeker has good reviews of the Pentium D and the Athlon 64 X2. These articles have a Geek Factor Rating of 2 stars: **.

Here is my 30 second summary:

Pentium D:
Basically just two Pentiums bolted together in the same package. They share the same 800 Mhz front side bus. All interprocess communications goes through this 6.4 GB/s bus. Due to heating concerns both procs run at lower clock speeds than the current single proc pentiums. The D requires new motherboards and chipsets, but is priced almost half of the X2 price.

64 X2:
The core was designed from the beginning to be multi-proc. The architecture communicates between the two procs via hypertransport that when combined with the memory bandwidth yields 14.4 GB/s of total processor input/output bandwidth. The procs are available at the same clock speed as their single proc counterparts. The X2 does not require a new MB, you can drop it in your 939 slot with a bios upgrade, but is is nearly double the PD price.

Performance:
Best to read the reviews and draw your own conclusions.

[H]ard|OCP had a great article on the X2 a few weeks ago that I didn't get around to posting. AMD has done an awesome job in the performance and power consumption of this processor. Having dual procs (like tons of memory) is just an excuse for the average app to have 10 threads on windows, but I'm still happy to have one of my cores free to use while all the various background processes are trickling away on the other one. I dedicate one of the procs as my Dirty Harry proc - handling any dirty job that comes along. Ha ha ha.

The cost of these is going to be high for a while, but it is absolutely insane the types of performance we're seeing nowadays. It's almost TOO fast (nearly all operations nowadays are IO bound). How cool is it that the X2 dual core still uses the same heatsink/fan and socket as the single core!
