I was advised to build a Core 2 Duo system. But, what is the equivalent AMD chip series?

Thank you.

The new Phenom 2 X3's have around the same bang for the buck.


High enough clocks to be better than the quad but the extra core helps in some multithreaded apps.

And they overclock fairly well too.

Oh, what series of C2D were you talking about?

The ones I mentioned compare with the e8xxx series.

Good C2D processors are comparable to maybe the original Phenom X4 or X3.
Slower C2D (celeron?) processors are equivalent to maybe the Athlon X2.
C2Q is equivalent to Phenom II X4.


It really depends what you're doing. The higher end C2D had no real competition from any of AMD's dual core processors, so AMD's equivalent is 3-4 processors, and this is only an ok comparison if you're talking about multitasking or using programs that can use 4 threads. If you're talking about something that uses 1-2 threads, then AMD doesn't really have an equivalent.

I am looking at the E5200. I have an idea of what system I want to build, and now I want to spec a comparable system with AMD/ATI components to compare the cost. The last time I bought as computer, AMD was still cheaper than Intel for similar performance, that was in 2004/2005.

I do not know how to compare the chips, are the numbers at the end the "comparable," at one point there was a number system like that to compare them based on some intel chipset and its potential gigahertz speed or at least AMD was giving their chips numbers like that. Use pricewatch.com as a baseline to easily compare prices, a core 2 duo e5200 is $30 more than a amd x2 5200. But the Pentium Dual Core are also $30 cheap that the Core 2 Duo's also.

Shawn - isn't that a severe problem for AMD? I am seeing all sorts of game specs with Intel Core 2 Duo listed in the requirements (and "or AMD equivalent"). I am not a gamer, but there are some games I might be interested in.

E7xxx Core 2 Duo = X3 Phenom 2
E8xxx Core 2 Duo = X4 Phenom 2
E5xxx Pentium = X2 Athlon

Amd's have HORRIBLE L2 cache which makes them lag even more behind the Intel Design.

The e5200 is not a C2D - it's a Pentium based on the C2D architecture.

AMD X2 6000/6400 and 7550/7750 are pretty comparable, if we are comparing at stock speeds. They all have slightly different strengths and weaknesses.

e5200 overlclocks better than those X2's.

It was never really a problem for games, but it does get in the way of penis waving. The E7400 and Phenom 9600 are about the same price and perform about the same in a lot of games, but people don't like the idea of needing 4 AMD processors to do the same amount of work as 2 Intel processors. Personally I don't really care how many processors it takes. Show me the price, show me the performance, and I'll decide based on those alone.

games


Sticking at stock speeds or close to stock speeds, I would pick the AMD quad core. Do you plan on overclocking at all?

E5xxx Pentium = X2 Athlon

Amd's have HORRIBLE L2 cache which makes them lag even more behind the Intel Design.

What have you been looking at? In many cases, PhII X3 equals or beats e8x00 (and, by extension, the e7x00, which only trail by a little). Check out the reviews at AT, TR, etc.

Why is the L2 cache "HORRIBLE"?

From Tech Report:

Conclusions Well, jeez, it's hard not to like the Phenom II X3 720, which is just a bundle of gimpy goodness. Thanks to its higher clock speed and larger cache, the X3 720 quite frequently outperforms its bigger brother, the Phenom II X4 810, even though it costs less. And, at 2.8GHz, the 720 is fast enough to match up pretty well against the Core 2 Duo E8400 in many applications?including games?that tend to run best with fewer and faster cores. In more widely multithreaded apps where the 720's third core kicks in, the Phenom II X3 almost always outruns the E8400, sometimes dramatically. Oddly enough, the 720's combination of three cores and relatively high clock speeds may be the ideal trade-off for the current state of PC software. Who knew? Add in the X3 720's fairly tame power consumption, its apparently excellent overclocking proposition, and the fact that?regardless of memory type?the Phenom II has a superior system architecture to the Core 2, and the E8400 starts to look rather weak by comparison. The Phenom II X3 720 is our new favorite among mid-range PC processors. Look for it to secure a place in one of the builds in our upcoming system guide refresh.

where would the old e6xxxs fit in? They run about the same as the e7s right?

You can't really compare more cores to more clock speed directly. Saying an Intel Core 2 Duo E8400 is equal to an AMD Phenom II X4 810 or an E7400 is equal to a X3 710 is completely subjective. It all depends on what you're going to use it for.

1. Internet, word processing, and general use? Get a dual core with a decent clock speed and save on power consumption, unless it's going to be 2-3 years before you upgrade again (in that case, grab a quad core).
2. Overclocking? AMD's Phenom II-based processors (X3 ###, X4 ###) overclock well from what I've heard, but Intel's Core 2 Duos are known for their excellent overclockability.
3. Gaming? Most games only benefit from dual cores, though some are starting to make use of more. Again, it depends how long before you'll upgrade again.
4. Rendering, encoding, or Photoshop? If the rest of your system supports the upgrade (4-8+ GB of RAM, fast enough hard drive, etc.) grab a quad core.

Take all of that into account, let us know what you'll be doing with the system, what your budget is, and what you currently have. Then someone can give you a real answer.

I have no plans to overclock. That would only happen if there is some game I would buy that my system can not handle.

Ok, but what are the goals of the system? Gaming and general use? Also, what's your budget and how long do you expect it'll be before your next upgrade?

Do you already have a motherboard, memory, etc. or will everything be new?

Curse, I will probably soon make a post int he general hardware section for a system, I just originally wanted an idea of what the comparable series would have been. The web searching I did found comparisons back to 2006, and that is a long time away in hardware terms.

I'm just talking from personal experience. My X4 P2 wouldn't overclock for SHIT over 3.8Ghz but my E8500 went to 5Ghz with ease.

If you're looking for potential and a better design intel is the way to go. If you're on a budget intel is also the way to go. Pair an E5200 with some 1066 DDR2 and a nice mobo and 4ghz is EASY and cheap

Understandable, but keep in mind what I said - there really isn't a good comparison these days. It all depends on what you'll use it for. Quads are great for things that use all four cores, while gaming still generally benefits the most from high clock speed (which you can obtain easily with a dual core and save some power at the same time).

It was easy until Core 2 Quad came around. :p

At this point, I would take a quad core from either side over a dual core. There are already some games that just run horribly on anything but a quad. This number will only increase with time. So even if your goal is just to game, might as well build with a quad.

Rick, are you even reading what the OP said? He has no plans to overclock.

I wouldn't say 4Ghz is "easy" for an E5200. Not at "safe" voltages. In fact, I haven't seen one hit 4Ghz yet, at 1.4v actual or less.

No overclocking? Where's the fun in that? May i suggest a Amd 6000+ Brisbane core then. Should do well for exactly what you want to do.

That is one link and at 1.389 volts. To say it is common is silly.

Since Rick James got his E8500 to "5GHz easily" and his i7 to 4GHz then all intel chips must overclock that easily *rolls eyes*
