Like the superheroes of old, the AMD Phenom streaks out of the night to lay waste to your enemies. The 9950 Agena has 4 cores that run at 2.6GHz. The quad-core Phenom processor has 128KB L1 and 512KB L2 caches for each core and a total of 2MB L3 cache to buffer really heavy data flows.

Memory transfers get faster than ever. HyperTransport Generation 3.0 mode allows up to 16.0GB/s of bandwidth. Add that to the 17.1GB/s from the integrated memory controller for an amazing 33.1GB/s of memory bandwidth. This unprecedented bandwidth is needed to feed the data hungry AMD64 with Direct Connect Architecture cores.

You'd think that all of this power could get too hot to handle. Think again. AMD's Cool'n'Quiet 2.0 technology works with CoolCore Technology to minimize heat while keeping power and efficiency up. Now the cores can shut down unused parts of the processor when not in use. This saves power and helps to reduce the amount of heat generated. This function is built in so there's no need for drivers or BIOS updates.

  • newegg AMD64 Quad-core Technology AMD64 is designed to enable simultaneous 32- and 64-bit computing with no degradation in performance. With Quad-core technology, four complete processor cores on a single die run at the same frequency to deliver exceptional multi-tasking power, allowing users to surge through the most demanding processing loads, including advanced multitasking, critical business productivity, complicated visual design and modeling, serious gaming, and visually stunning digital media and entertainment.
  • newegg HyperTransport 3.0 Technology HyperTransport 3.0 Technology (HT 3.0) is a high-speed, low latency, point-to-point link designed to increase communication speeds between integrated circuits in computers, servers, embedded systems, and networking and telecommunications equipment. With HT 3.0 technology the AMD Phenom 9950 Agena processor enjoys 4000MHz system bus speeds.

5 out of 5 eggsAn old gaming friend...

Pros: Solid and consistent performance
Overclock Stable on AIR COOLING
Extremely Durable

Cons: I seriously can't name any other than TLC timing bug. I didn't know it existed until year 3 or so, but once that was handled, this monster's potential was truly unleashed.

Other Thoughts: This was my first real upgrade. I have seen so many amazing worlds and done so many amazing things because of this CPU. It is finally time to retire my old friend. Over to Intel I go, but I will never forget this absolute IRONMAN of a chip. From hot 3rd floor apartments, to humid summers in our new rental house, this beast has kept me playing literally without fail. Not a crash, not a bug, nothing caused by the CPU itself. EVER. Even when OC'ing. It was always my memory or GPU causing issues. It's running solid at 2.9 as I write this, and my new parts ship in the mail. Hats off to AMD for this one, minus the pesky little mishap with TLC timing, I don't think I'll ever have another piece of hardware as reliably awesome as this one. Thank you guys for the years of fun. Cheers.

5 out of 5 eggsSolid processor

Pros: Great processor. Still running strong

Cons: Runs a little hot, but I've seen others say the same thing about this chip

Other Thoughts: I've gotten my money's worth out of this chip.

5 out of 5 eggsWorth Every Penny

Pros: Purchased this in 2009 for gaming build and is still working great in 2011. Overclock-able to over GHz with the right cooling. never have any shudder of speed or stability running on stock speed.

Cons: OEM Heat sink was made for x2 but sold with the x4 so it runs really hot. Mine gets up around 65 Celsius on stock speed. I would recommend getting aftermarket cooler.

5 out of 5 eggsProcess Juggling

Pros: Cranks through multiple processes like a minature mainframe. Still scores 7+ in Windows 7 even though it's becoming a little dated. I run two VMware guests OSs plus play BF2 with no stuttering or slowdown. Even tried it one time with a DivX encoding running also and still no slowdown.

Cons: Not an AM3 so it will never get to play with DDR3 memory which would be neat to see. Does generate a bit of heat.

Other Thoughts: Mine is coupled with a Koolance EXOS2 so getting the heat out isn't a problem; I'd be a little careful running this (especially with a high-end graphics card) on air unless you have a really good case with excellent flow. Also, if your motherboard doesn't sport 8 phase VRMs or better, you'll need to cool those down somehow--they get brutally punished with core voltages spiking up and down and heat build-up.

4 out of 5 eggsGreat Bang for the $$

Pros: Low cost, fast speed, overclockable.

Cons: Runs HOT! AMD still uses vertical standing pins for chip install.... easy to bend if you aren't paying attention.

Other Thoughts: Got this in a bundle deal with the Biostar motherboard, and 4 G of ram for $220.... hard to go wrong at that price!

But I would definately make sure you have a WELL vented case (at least 2 120mm case fans), and get a GOOD 120mm CPU cooler. I used a 120mm Zalman cooler and I idle at 28-30 °C and hit 32-36 °C under load. I would not run this chip with a stock cooler.

5 out of 5 eggsYou're crazy to pay for anything more

Pros: Used on a Gaming Rig I built August 2009, this processor is lightning fast.

Running SO COLD and SO FAST with a rosewill aftermarket air cooler. O/C'd to 3.1 STABLE AS HELL
you could honestly go to 3.5 on Air cooled and have a great "daily driver"

This thing dollar for dollar GHz for GHz is the fastest processor your money can buy.

Battlefield 2142 1080p res and Full settings? Hell yeah
Oblivion on full settings at 1080p? Not even a blink
this is on a 9500 GT card, and 4 gig of ram, can you imagine if i actually spent more than 100 bucks on a video card? the universe would spilt... no doubt.
Whatever you want it to do... it does, no questions asked.
i can't say enough good things about this CPU.

i upgraded from a dual core Turion X64.

Cons: I can't afford to buy the whole world one.

Other Thoughts: Dont think about it, AMD makes some great products, this chip is a budget rig masterpiece.

5 out of 5 eggsAwesome Processor

Pros: -Overclocked to 3ghz
-Doesn't go above 50c with stock cooler and artic

Cons: -None, If i wanted fancy features i would have shelled out 100 more dollars

Other Thoughts: awsome!

5 out of 5 eggsI love it

Pros: Fast and efficient.

Cons: Runs hot and included heatsink/fan is so so.

Other Thoughts: I've replaced the heatsink fan twice trying to cool it down under load. First an AC Freezer 64 Pro and now a ZALMAN CNPS 9500. The ZALMAN works better, about 2-3 degrees drop over the AC.

Part of my heat issue is with my case. Once I get the airflow out of it better I'm sure the temp on this sucker will drop.

1 out of 5 eggsTERRIBLE EXPERIENCE !!!

Pros: Wish there were some... This product should have been awesome, but Newegg ruined the experience.

Cons: Memory Channel #2 and #4 would not read RAM - possible bad memory controller. RMA'd it and Newegg refused to replace. First bad experience with Newegg - totally shocked that they refused to replace a defective product (Retail version too).

Other Thoughts: This has been the worse experience I have ever had with Newegg !!! After contacting customer service on two different occasions and being told that they would have a manager contact me with an explanation as to why they weren't replacing my part - STILL NO ONE HAS CONTACTED ME ! This is not the same service I had grown to know from Newegg, and needless to say I'm very dissappointed and will search for a better vendor next time.
