AMD Phenom II X4 810 and X3 720 BE Processors

Article Index:   

Performance Summary: The Phenom II X3 720 Black Edition and X4 810 processors performed very well in multiple categories.  According to their respective benchmark scores, both processors are competitive with similarly priced offerings from Intel, trading victories depending on the application being tested.  Overall though, Intel still has the performance edge clock-for-clock and core-for-core.  The X3 720 Black Edition, however, finished well out in front of even a higher-clocked 3.0GHz Core 2 Duo in multi-threaded applications, due to the X3's third processor core.  Both the Phenom II X3 720 Black Edition and X4 810 processors were also very good overclockers, and they were quite power friendly as well.


Although we showed you only two new Phenom II processors in this article, AMD is announcing immediate availability of the following five new AM3-packaged Phenom II processors today, the Phenom II X4 810, the Phenom II X3 720 Black Edition, and the Phenom II X3 710, at prices of $175, $145, and $125, respectively, in 1K quantities, and the Phenom II X4 910 and Phenom II X4 805 (pricing wasn't available for the X4 910 and X5 805 as of this publication).  At these prices, and with the excellent overclockability these processors have shown, we suspect they will be very popular with the enthusiast and gaming communities.  The Phenom II X3 720 Black Edition is an especially enticing product.  Couple this unlocked processor with an inexpensive 790GX based motherboard and 4GB of DDR2 RAM, and you've for yourself a killer overclocking and gaming platform, for right around $300.  That third core in the X3 also offers marked performance benefits over most dual-core CPUs in multi-threaded applications, which is something rather important to consider.  These new processors have also proven to run cool and consume less power, relatively speaking, making them well suited to quiet or HTPC system builds too.

The flexibility of the AM3 platform, with its support for DDR2 and DDR3 memory types, is also a big plus.  Existing owners of socket AM2+ plus motherboards looking to take advantage of AMD's latest processor offerings can rest assured that these new chips will plug right into their existing systems and just work, with no need to upgrade any other components.  And new system builders, in the market for an affordable, high performing platform have the flexibility to choose from a wide range of motherboards and memory types, at multiple price points.  If you want the best AMD has to offer, you've got the 790FX and DDR3; want to save a few bucks and there's always the 790GX (or other 7x0 series chipsets) and more affordable DDR2.

They may not break any performance records in their stock form, but the Phenom II X3 720 Black Edition and X4 810 processors are definitely worthy of consideration at their respective price points and are excellent additions to AMD's affordable processor line-up.  They also offer a glimpse at what AMD has in store with, higher-clocked, future AM3 processors.  Using DDR3 memory with these processors resulted in performance gains across the board.  We can't want to see what a fully loaded X4 Black Edition can do when overclocked to almost 4GHz with some speedy DDR3-1600 memory.  Fun times lie ahead.


  • Good Performance
  • Highly Overclockable
  • Low Power
  • Very Affordable
  • Compatibility with AM2+ and AM3


  • Not Quite as Fast as Core 2
  • Confusing Naming Convention

Phenom II X3 720 Overclocked to 3.6GHz for about $145? Sounds rather tasty!

Can you get these yet? May have to retire to trusty old Pentium D.

Yes... this is what I waiting for. Now I can start pricing the new AMD Phenoms with DDR3 support and the related chipset MB's. I am going to put either one of them or a I7 and related system components into a new system. but you couldn't price them against each other until they were actively on the market of course. I think I may still wait for a minute to let the components get totally current driver wise etc.. What graphics implementation do you guys think would be the most advantageous? I was thinking either a 4870 or dual 4850's or maybe an Nvidia card but I want something that will do everything on a best perf. VS. price basis. How soon do you guys think the next GPU will hit?

What cooler were you using on the chips cause by rights you shouldnt have any trouble with a decent air cooler to hit 4ghz, especially on that triple core. The oc on the 810 is low, nearly all other review sites have that thing running at 3.7-3.8 like they do with the 720be, and a few sites have gotten the 720be to 4ghz on air.

AMD is on a roll with these Phenom II's, they just need a extreme CPU.

Bring back the FX!!

Phenom II X4 FX 990 3.4 GHz??

Der Meister 5 years ago

OOO I havent seen a FX series from AMD in some time, the last one i can think of was the 70 or 71 i think....

Which of Amd,s current offerings as far as performance would be on par with Intels current i7 / 920? And what kind of price range are we looking at!?

InfinityzeN 5 years ago

Sadly, none of AMDs current offerings are on par with Intels Core i7.  They finally managed to get up to Core2 level.

yoda8232 5 years ago

That's because the i7 is totally brand new technology while the AM3's are just AM2+'s with DDR3 support and some changes.

Look at the cost difference too.

AMD has been proven by Anandtech to run video games as well as or better than C2Q and according to them the game flows much smoother because of the onboard memory controller. Who can afford i7? There's great value in the new Phenom II's and the X4 955 will be out later this month which has been commonly shown to run over 4 GHz with low voltage and air cooling. Personally, I'd love to have one but their going to debute at over $300. Broken Heart

totally agree. An FX variant is what AMD needs to throw out next. I think if they could get an FX version out that came close to comparing to an i7 920 for around the same price they could get a huge share back.

FX clocked at 3.6 GHz with some special feature versus the other Phenom II's.

The X3-720 is a good CPU. I unlocked the 'hidden' fourth core and OC'd mine to 3.2 on air. With DDR-3 RAM in it, it's playing all of my shooters on high settings without problems @1680X1050 resolution.

So with the right motherboard, you get an extra core if you get lucky enough. Even with just three of them, it's a solid performer too.
