Mobile CPU Wars: Core 2 Duo vs. Core Duo


Recommended Posts

While the world has been focused on the launch of Intel's desktop Core 2 Duo, codenamed Conroe, Intel has been readying its mobile counterpart also called Core 2 Duo. With only a few changes to its desktop counterpart -- mainly its lower clock speeds and FSB frequency and thus lower power -- there's no reason to call the mobile version anything but Core 2 Duo.

There hasn't been much interest in Core 2 Duo on the mobile side for two major reasons; for starters, unlike on the desktop, Intel already had a very competent mobile CPU - the Yonah based Core Duo processor. Seeing as how Core Duo is the predecessor to Core 2 Duo, you can already expect that Intel's current mobile performance is quite good.

The other major reason there's not much hype surrounding Core 2 Duo in notebooks is because there's simply not the level of competition from AMD that we had on the desktop. While AMD's Turion 64 and Turion 64 X2 are good processors, you simply can't find them in nearly enough notebooks, and definitely not in as unique packages as you can find Intel's Core Solo and Core Duo processors. AMD is hoping to rectify this situation by both working on a lower power mobile CPU architecture and acquiring ATI to help complete its platform offering on the mobile side.

I liked the conclusion...

General application performance can improve a bit by switching to Core 2 Duo, but the biggest performance gains are associated with 3D rendering and media encoding tasks. Considering the nature of the improvements to Intel's Core 2 processor, the areas in which it succeeds are not surprising. If you use your notebook as a professional rendering or encoding workstation with no desktop in sight, then you'll probably consider Core 2 Duo a lot more carefully than most.

One of the items that clearly stands out is that discussing gaming performance on laptops is largely an academic endeavor, as the vast majority of shipping laptops are going to be completely GPU limited. We will hopefully have some results from a high-end gaming laptop in the near future, at which time we can detmine how much of an advantage Core 2 Duo really has over Core Duo. The designs are similar enough that we don't expect a huge difference, and the lower FSB bandwidth will certainly limit performance potential more than on the desktop. However, we would expect a difference somewhere in the range of 5-15% in most games if we can remove the GPU bottleneck as is evidenced by the Oblivion results.

did you guys know that intel will be relasing its "quad core" processor at the start of next year? :)

i think that'll greatly help the new nvidia "quad sli" to melt some faces =P :P

now if nvidia would hurry up an release their board that supports all that i think they'll corner the market on almost all high end rigs, not to mention giveing computers that power they need to achieve autonomous conciousness, lol

(chuckles quietly to himself) only a matter of time now my pretties until the good doctor wright completes his code in sc5 that thinks for itself! MUHAHAHA! :)
