Phenom Two X4 955: AMD'due south Dragon Platform Evolves
AMD Phenom Ii X4 955: Finally, A Flagship
The concluding acme-end processor we saw from AMD was launched in January of this twelvemonth. Running at 3 GHz, information technology leveraged a brand-new-to-AMD 45nm manufacturing procedure and a number of notable micro-architecture enhancements, including a larger (and faster) L3 enshroud, Cool'north'Quiet 3.0 applied science, and improve co-operative prediction.
But, as mentioned, the subsequent introduction of Socket AM3 the calendar month later on saw a brand new platform flanked by more mainstream CPUs, taking a lot of the shine off of what we causeless would be a faster hardware combination.
At long last, AMD is unveiling a new flagship to go along with AM3: its Phenom Ii X4 955 running at 3.2 GHz and equipped with the same half dozen MB shared L3 enshroud.
In that location's really not much to add that hasn't already been said about the Phenom Two family, merely to epitomize, the chip is armed with 64 KB each of L1 data and educational activity cache per cadre, 512 KB of L2 cache per core, and again, that six MB shared L3.
An integrated 128-bit DDR2/DDR3 retentiveness controller (running at 2 GHz by default) interfaces with a pair of 64-bit channels. If you're using the X4 955 on an AM2+ motherboard, speeds of upwards to DDR2-1066 are officially available. If you're using it on an AM3 platform, you tin install DDR3-1333, though it should be noted that only one module per channel works at that frequency. And whereas AMD shipped its Phenom 2 X4 940 with a ane,800 MHz HyperTransport link, the X4 955 accelerates that to 2 GHz--but like the other AM3 processors.
The chip's nominal voltage range is .875V-1.5V, similar to the Phenom Two X4 940, then we won't be surprised if power consumption falls within the previous flagship's ballpark. In fact, this new processor also sports a 125W TDP.

The New Dragon: Pictures, Prices, And Comparisons
I've mentioned this earlier, but there was a time when AMD shunned the platform concept, preferring to focus on processors alone. I was critical of that approach back and so and recognized the value of Intel's CPU, chipset, motherboard, networking, storage, etc. arroyo, especially in the workplace. Arrangement builders favored it, and for skillful reason given centralized support.
At present AMD is fully on the platform bandwagon and nosotros think the decision is a good one. In fact, the company is thumping its platform drum then hard that it's difficult to believe it ever wanted anything different. First, it was Spider. Then AMD wanted to talk Dragon. And now the company is fawning over this "Dragon Update."
Exercise what you will with the marketing terminology—information technology all boils down to a hardware combination. Dragon 1.0 consisted of a Phenom Two, a Radeon Hard disk 4800-serial GPU, and a seven-serial chipset. All of those components are nevertheless in play.
This update nudges united states upward 200 MHz with a flagship running at 3.two GHz. It gives us the option of adopting DDR3 memory and a Socket AM3 interface. Information technology's available alongside ATI's new Radeon HD 4890 graphics menu. And it includes a new processor-in-box reference cooling solution, which is just a tad smaller than its predecessor.
Practise all of those "upgrades" emerge at comparable prices to hardware at the time of AMD'due south Dragon launch in January? It'southward a shut match-up. Nosotros originally calculated a processor/motherboard/DDR2 memory parcel at roughly $450 ($275 for the X4 940, $130 for an inexpensive 790GX motherboard, and $50 for iv GB of DDR2). Today's update can be done for roughly the same price. The X4 955 is launching at $245, only the price savings is consumed by the 4 GB of DDR3.
We only so happen to exist using a pricier motherboard in our evaluation hither: Asus' $190 M4A79T Deluxe, based on the 790FX, rather than the 790GX chipset.
