AMD Performance Midrange

The introduction of Phenom II has made putting together an AMD performance midrange a joy again. While the Phenom was an honest competitor at the price points where AMD chose to compete, the poor overclocking of the AMD Phenom compared to Intel Core 2 Quad processors was always a nagging reality. Phenom II changes all that, and AMD in 45nm clothes is once again a screaming overclocker. We reached 3.9GHz in our testing for the Phenom II launch with a Phenom II 940 CPU. That same CPU is the starting point for our AMD performance midrange PC.

For detailed information on the Phenom II, please read our AMD Phenom II launch article and the follow-up Phenom II X4 810 and X3 720. The Phenom II 940 at 3.0GHz is the fastest of the currently shipping AMD Phenom II processors, but that will likely change in a few weeks. The Phenom II is very similar in L2/L3 cache configuration to the Intel Core i7. Performance is also similar to comparably priced Intel midrange chips. As the first 45nm AMD processors the Phenom II also overclocks very well, finally approaching the overclocking levels enjoyed by Intel since the introduction of the Core 2 Duo.

The component that made the early Phenom II systems affordable was the Foxconn A79A-S motherboard, which is compatible with AM2+/AM2 and is based on the AMD 790FX chipset. The selling price of this Foxconn A790FX board was $224 just a few months ago. Today it is available for $140, and we have seen it as low as $105 with the rebates that come and go on this board.
 
This Foxconn board offers true dual x16 PCIe slots, which may be important if you plan to run Crossfire. If that is not important and single x16 or dual x8 PCIe will be fine, then you might consider a 790GX board with DDR2 support. These can be easily found for $100 or less, saving $40 to $45 on the system price. Performance is similar to the 790FX, though our Motherboard Editor still recommends the older FX chipset where squeezing the very last bit of performance matters.

The Phenom II is not the hot CPU you find in the Core i7, but it still benefits from third party cooling - particularly if you plan to overclock. We paired the Phenom II 940 with the Xigmatek Dark Knight, which performed well in the lab. At $40 the Xigmatek is also an excellent cooling value.

Since the Phenom II 940 does not support DDR3, our DDR2+ motherboard was populated with a 4GB kit of OCZ Reaper HPC DDR2-1066. This memory is rated at a fast 5-5-5 at DDR2-1066 and it performs at faster timings and lower voltages at slower speeds. Whether you use it as a stock DDR2-1066 memory or overclock it to its limits, this OCZ memory should provide the headroom you need to bring out the best in this system.

The case for the Phenom II performance midrange system is the well-regarded Lian Li black all aluminum case. This Lian Li case has a reputation for exceptional quiet with its four 80mm fans with a fan speed controller and the excellent heat dissipation you expect from an all aluminum case. What is unique is the $40 savings on this case through the month of April, which reduces the cost to $100. There is even a side window for those who like a view of their working system.

Other components in the AMD performance midrange system are the same used in the Intel performance midrange. You can find descriptions and thumbnail images of those components on the previous page.

Finally, you should notice that the AMD performance system, using the current top Phenom II and DDR2 memory, is around $180 cheaper than the Intel Core i7 performance midrange system. The reason for this is very simple, and that is that the Core i7 is a better performing system. AMD and Intel are competitively priced these days and the comparative costs of an Intel or AMD CPU is now a good indicator of the performance. There are always exceptions to a broad statement like this, but generally pricing and performance are fairly gauged in today's market.
 
You might also consider waiting for the AMD Phenom II high performance CPU that fully supports Socket AM3 and DDR3 memory.  AMD will soon replace the 940 and 920 with updated processors that fully support the latest Phenom II AM3 socket.  Performance of the 940/920 replacements will not likely be better than the current 940/920, but the future Phenom II upgrade path will be cleaner.

    Our Motherboard Editor, Gary Key, tested DDR2-1066 memory in the recommended Biostar board. It worked fine at DDR2-1066 speed, and of course faster memory will work fine at slower speeds and faster timings than rated if that is needed. That was not necessary though, as DDR2-1066 worked fine at rated speed.

    I suspect the Biostar spec was written BEFORE the AM3 chips were introduced, and should more properly read AM2+ or LATER required for DDR2-1066 support.

    AM3 CPUs will work in AM2+ motherboards, but AM2+ CPUs can't work in AM3 motherboards. The AM3 CPUs have both DDR2 and DDR3 controllers, which is why they're backwards compatible.

    You shouldn't include rebates in the price of a system unless you've actually bought that system and received the rebate. They are such a crapshoot it's a little dishonest to use them in an article.

    I've probably filed for close to 100 rebates on computer equipment, and only failed to receive 1. That was from MSI on a video card, they required the Newegg Invoice that is emailed to you instead of the order confirmation that everyone else accepts. It once took a year and a couple resubmissions to get a Seagate rebate, but I did get it.
  • Wesley Fink - Wednesday, April 8, 2009 - link

    Right now it is hard to NOT use rebates in pricing, since they are everywhere in component pricing. We hate rebates also, and much prefer a reduced price. We have listed the current rebate amount in the description to disclose as much info as possible. That seems a fair way to do it.

    Rebates are NOT dishonest and they are certainly legal, but it is frustrating for most to pay more up front and then have to wait months for their price reduction checks. Personally I have received every rebate I ever claimed, but it sometimes took way too much time to get the check.
  • Wesley Fink - Wednesday, April 8, 2009 - link

    NOT paying rebates for valid claims IS illegal. If that happens to you contact the company and ask why you haven't received the rebate. You should also keep copies of everything you send them in case you have to resubmit. It that doesn't work file a complaint with your State Attorney General's office.

    If all this is too much for you as a buyer shop for components with up-front price reductions. NEVER buy an item for the good Rebate price if you find mailing rebates is too much trouble. Manufacturers normally DO pay rebates, but they count on a lot of people never sending in the paperwork. Those that send in rebates are subsidized by buyers that don't.

    Agreed it's consumer FRAUD... the problem with these rebates and the like is that the law regarding them and internet related based deals is, the complete lack of law-enforcement. They are so behind the times regarding cyber "crime," that the actual pursuit of your money, cost MORE than you'd receive. I've got a rebate from Spectre 22" monitor that I filed 3yrs ago that never came. I complained blah blah... nothing. Pursuing was fruitless, for $35. To me it wasn't, but to the Inspect gen etc... they aren't going to do a thing for anything less than near class-action.

    Did you pick the Xigmatek Dark Knight because of its price? If so, what would you have chosen for somebody willing to spend more? I'm hoping you say spending more isn't necessary with the 940.
  • Wesley Fink - Wednesday, April 8, 2009 - link

    The Xigmatek cooler tested very well in lab systems and is one of the better coolers you can buy. The fact it is also reasonably priced is just a nice plus. I personally use a Thermalright Ultra 120 Extreme with a Scythe S-Flex fan, but I find the Xigmatek nearly as effective and I have no probelm recommending it.
  • BPB - Wednesday, April 8, 2009 - link

    Thanks. I have the Thermalright Ultra 120 Extreme in my Intel case, and am looking to get a nice cooler for my AMD CPU. Now I have to decide, I'm leaning toward the Xigmatek.
