Athlon II X3 435: AMD's Three-Core, 2.9 GHz, $87 Triple-Threat

Athlon II X3 435: AMD's Three-Core, 2.9 GHz, $87 Triple-Threat
By

Today AMD introduces what might turn out to be the ideal budget CPU, with three cores for multi-threading, a relatively high 2.9 GHz clock speed, and an impressive sub-$90 price tag. How does it stand up to the rest of the company's Athlon and Phenom IIs?

After the launch of the Athlon II X2 and Athlon II X4 CPUs, it would be difficult to feign surprise at the introduction of the new Athlon II X3. We all knew it was coming, we even mentioned the upcoming X3 flavor of Athlon II in our Athlon II X4 620 launch story.

While the shock and awe might have been spoiled, the Athlon II X3 certainly isn't. AMD's vanguard model is the Athlon II X3 435, and it combines two very compelling components: a relatively high clock speed of 2.9 GHz (that's 100 MHz faster than the top-of-the-line Phenom II X3 720 Black Edition), and a relatively low MSRP of $87.

AMD already has the sub-$120 CPU market sewn up with a glut of Athlon IIs and Phenom II X2s and X3s, but at under $90, does the new Athlon II X3 435 offer the best value in the bunch? Let's find out.

    AMD CPUs been appealing to budget builders lately :)

    AMD is really thriving in the budget sector, I wonder how the i3's will affect the market. I hope AMD can get back to head to head with Intel on the high end though.

    Smart move by AMD by attacking the budget crowd (especially around the holiday season). I am surprised how well this thing did against the X2 550! Seems like a good candidate for a budget gaming/multipurpose build. Any release dates available (for NewEgg)?

    I think my HTPC just found its new processor, been running a 5200+ for the last while

    this is awesome but (and its a big one) i kinda wanted to see something that pwns intels core i7 in everything. Kind of like what they are doing in the graphics department but total domination. How long will i wait!!!

    2 cores 2 threads?

    3 cores at almost 3Ghz for this cheap? Hmmm not a huge AMD fan but this is plenty of CPU for most people. I would snap one up if I was building a system right now.

    That's one impressive little chip! Pair this with a 770 chipset and you'd have the basis for a cheap and cheerful gaming PC!

    Aha! Thanks for catching that. After I had done the testing I was playing around with disabling CPU cores in the OS, and I forgot to turn them back on to take the screenshot. Fixed!

    did the disable core of Athlon II X3 435 can be unlock ?

    The RAR and 7z archive formats make use of a large size 'dictionary': a small store of patterns that, when used on a solid archive, can help achieve very high compression ratios. If this dictionary can be made to fit in fast memory (ie. cache), then comparing its patterns to currently compressed data can yield tremendous speed improvements:
    - the dictionary doesn't have to be called from RAM on every new data page, which frees memory bandwidth
    - when the dictionary is half the size of cache, then uncompressed data can fit in cache too, thus actual compression doesn't need 'paging' from memory.

    As an example, the PKZIP algorithm (used in .zip files) has a fixed dictionary size of 64 kb; .zip can't handle solid file compression either (the same algorithm can be found in gzip, but when used with the tar archiver, can in essence achieve solid file archiving, which can yield non negligible compression improvements).

    In 7-zip, when creating the archive, try setting up the dictionary at a size lower than half the biggest consolidated cache the least gifted CPU has, and compare again: performance will in fact be rather close. However, if you go over the cache's size, performance plummets.

    About AVG appreciating core counts better than CPU speed: this could be explained by how I/O intensive a virus scan is; and since Vista sucks at I/O, what's left to compare are how many file handles can be opened and used simultaneously. A test that could be done:
    - Install AVG on Vista, XP and Linux
    - Run a scan on the same file set (be mindful though that the Linux file set should be put on an ext3 filesystem, NTFS access still being rather CPU intensive on Linux)
    - see if there are differences.

    with mutlicore cpus reaching sub $100 pricepoints, do developers still have an excuse that "not everybody" has a multicore rig?

    even an atom netbook can do 2 thread simultaneously.

    kudos to amd for launching budget options ... look at core lga775 prices they havent moved as expected even with lynnfield ... htpcs are going to benefit especially with the low power options ... 3 cores great for encoding and bluray playback etc ...

    And I thought I would wait till new year for an extra build for my household. Great AMD!
    I really hope they get their act together and hit Intel hard on their flagships just as they did with Nvidia.

    This way no one will buy Intel for budget rigs...

    "We will also be simulating an Athlon II X3 720 with a Phenom II X4 965 by lowering the CPU multiplier and disabling the forth CPU core" Close but not quite, heads up.

    Nice article by the way and I haven't even gotten to the benchmarks.

    Pretty amazing performance for such an extremely low price.
    Looking at the gaming benchmarks I'm impressed.
