A 4.1 GHz Dual Core at $130 - Can it be True?

A Budget CPU At Top Speeds, Continued

As one of our more enthusiastic readers wrote to us a few years ago, when we were chasing new overclocking records on what seemed like a daily basis: "I'll knock your numbers down to the ground." In this case, he was referring to the video encoding performance numbers that a heavily overclocked system could post when compared to a stock PC. We've also seen another similar phenomena in days of yore, which ambitious (but older) users probably remember. For example, the Intel Celeron 300A, for which a 300 MHz clock rate was specified, worked flawlessly at 450 MHz. Foreshadowing our current champ, this low-cost offering also knocked a much more expensive Pentium II 400 into the back seat.

Can be had on the cheap: Intel Pentium D 805 at a price of $130.

The Pentium D 805 gives Intel an unassuming budget CPU for its processor portfolio, but simply overclocking the device to 4.1 GHz puts it ahead of top-of-the-line high-dollar processors. For overclocking aficionados this means one thing: the AMD Opteron 144, which led the overclocking pack until just recently, has been dethroned by the Pentium D 805. This latter processor is not only easier on the pocketbook, it's also a noticeably better performer, thanks to its dual core architecture - the Opteron offers only a single core.

    I am quite interested in your post regarding the D 805. Considering that it is now available for around $60.00 (03/20/09), it still sounds like a steal. We just upgraded our Adobe CS2 software to the new CS4 Master Suite, which caused the need for a graphics card upgrade. We have an nVidia GeForce GTX 260, but haven't installed it because our computer is a HP Media Center PCm7350n computers each with a 2.8 GHz CPU on a ASUS P5LP-LE mobo. Your article seemed to imply that there is software available that might adjust the clock from inside windows and we are wondering if it can on that mobo or if we will have to get a different mobo. If so, we are wondering what might be our most cost effective but stable options. We are certainly going to need a new power supply for the GTX 260, which requires 525 Watts. We are looking at just putting in PC Power & Cooling’s, Silencer 610 EPS12V power supplyand letting it go at that, but we are also thinking about upgrading the CPU and mobo if necessary.

    Of course, we would like to keep the cost down as much as possible.

    We have no idea where the best bang for the buck will be. For us a stable system is more important than blazing speed. Thus, the HP's worked fine for what we originally got them for; it’s just that our graphics and video production software are forcing upgrades in speed and power.

    The D850 chip sounds incredible and the power supply we already have to get will handle overclocking that chip. It even sounds like that chip will work in the existing mobo if we can find a way to change the clock speed from inside windows instead of from the BIOS. HP BIOS does not allow adjusting the clock speed in the BIOS but can't BIOS just be changed as well; isn't it just an EPROM?

    Anyway, even if we opt for changing out the mobo for another case compatible Asus mobo, we still have to answer the question of which board and chip combination will give us the most stable service for the least cost.

    Any ideas that might help us plan the most appropriate upgrade and the least cost?

    With the price of components that you need to make this run stable, and the amount of electricity that this would use, a cheap Core 2 and motherboard and DDR2 memory would cost you less in the long run.


    Intel Pentium Dual Core E5200
    Kingston DDR2 2x2GB 800MHz
    Gigabyte G31M-ES2C

    This should cost less than $200.
