Midrange CPU Roundup: It's Time to Buy

Throughout the past few CPU articles we've mentioned that now is an absolutely wonderful time to be building a new system thanks to incredibly competitive CPU prices. The AMD/Intel price war has really paid off in making the marketplace more competitive. The fact that you can buy a very fast quad-core processor for less than $300 is just incredible.
At the same time, it's very easy to get caught up in recommending the higher end parts simply because they are priced so low now. AMD's entire Socket-AM2 product lineup can be had for under $300, but we've primarily focused on the $150 - $300 range, when both AMD and Intel have some very powerful CPUs available at or below $100.
For many, these processors are great for primary systems built on a budget, but for others they make a solid foundation for a good second or third system, file server, or machine for a friend/relative. Price/performance means everything, but you don't always have the luxury of choosing a $160 processor over an $80 one, despite the incredible value of the former. At the same time, power consumption and noise matter tremendously, especially if you're building a Home Theater PC or file server, where CPU performance isn't necessarily the most important thing but building a quiet, power efficient system is.
Then there's the question of motherboards; it's finally possible to build a fast system that actually uses integrated graphics if you're not going to be playing any 3D games. Relying on integrated graphics will further reduce the power consumption and noise level of your system. There's no point in testing these CPUs with $200 - $300 motherboards, so we decided to focus on more affordable platforms, including testing with integrated graphics. This is the full experience: we're pairing $80 CPUs with $80 motherboards and seeing where they end up.
The question is this: if you're building a fast but affordable system, but you want it to be 1) low power and 2) potentially use integrated graphics, what do you do? We're about to tell you.

I too wonder about the Netburst admonition. There are probably millions of Netburst CPUs out there that are happily computing away with no thought of Anandtech at all; doing their thing; producing great results for their owners. The biggest concern I have seen is thermal and that, only in relation to overclocking. Assuming there are more than a few users that don't need to or want to overclock; then there are some great bargins in used Netburst Processors and accompanying motherboards.It doesn't appear to me that "...if you know what's best for you." is either technical, professional or helpful. Maybe it was meant as a joke...sorry it's not that funny.

Yes, you did. Given the combination of power usage savings, pure performance benefits, and overclocking ability (since you mentioned 3.6ghz on the Pentium D, I assume we can go with at least 2.4 out of an e2140, for comparisons sake), the C2D/Pentium E line is much better.
The problem with a lot of the "lol Pentium D overclocking" articles is they fail to overclock what they're comparing against. You take a Pentium D 805 and OC it to 4ghz, sure, the performance delta over an e2140 will be big. But apply the same cooling and thought into OCing the e2140, and that delta will swing the other way.

So what would make the most sense to change out the Pentium D805 to that would keep me at (or better yet raise the bar of) the performance I'm getting now? An OC'd e2140 or something higher up the ladder? I'm matching this to a 2gigs ram, an nice MSI SLI plat mobo, and an 8800gts320mb. I'd want something that wouldn't bottleneck the system which is what the P.D805 did when it was stock.

It's going to depend on a lot of factors. If you're gaming, a change in the CPU may very well do very little in changing any performance; especially at a higher resolution, the CPU may make NO difference.
I'd look into the e2140/e2160/e4X00 line, if you wanted to stay lower cost. At the VERY least, you'll get a boost in energy efficency: The Pentium Ds were and are power hogs, especially compared to the newer line.
What performance did you see increase when you overclocked the Pentium D? Did gaming increase? If so, then a C2D based system would be much better, regardless of an overclock; Netburst just don't handle the games as well.
If, somehow, you're running something that is AMAZINGLY well tuned for Netburst, you may see less of an increase. But these applications are rare these days, so I doubt you'd see that in most cases.

Anand did you do the power consumption tests on the overclocked cpus? I think it's important to know, if you haven't, can't you at least give us a rought estimation? It'd be greatly appreciated. Thanks.dm0r - Friday, September 28, 2007 - link
Thats a great article Anand, I missed this kind of roundup.Enjoyed a lot and the only thing is missing is the performance per watt, but anyway very good article.Thanks for sharing!eetnoyer - Friday, September 28, 2007 - link
Why not throw in the 4200+? I know it's 90nm, but I just got one for $74, and (for me)it looks like the sweet spot of price/performance for AMD. And, given how well tuned their 90nm process is at EOL, I wouldn't be surprised to see power consumption close to that of the 65nm chips. If you want, you could use the 65W version (it's only a buck more).Uter - Friday, September 28, 2007 - link
Anand, is the BE-2400 still coming out? Or, when you say that there are two Athlon X2 BE Processors, the BE-2350 and BE-2300, is that a subtle hint that we shouldn't expect to see it? I just want to make sure I pick one of these up while there are still available...bogda - Friday, September 28, 2007 - link
Oveclocking results are not fair. You chose horrible motherboards for AMD overclocking.For example, Biostar AMD motherboards cost 50-60 euros. They are much better overclockers than MSI or ASUS you chose. My Athlon BE-2300 easily overclocks from default 1,9GHz to over 2,8GHz with stock HSF.

I completely agree, the boards chosen for the AMD chips are horrible.Gigabyte's MA69GM-S2H and Abit's NF-M2 nView would have been far superior choices in every way...poor motherboard choices, very poor.
