AMD Phenom II X4 955 Pro Reviews

bjorn3d‘s review Edit

The Phenom 2 X4 955 BE offers great performance at a good price. You can use your existing AM2+ board and DDR2 ram then upgrade to AM3 and DDR3, making it an even better choice in economic hard times. If we had to place it inline with current Intel offerings, we'd say it fits roughly in with the Q9400 or Q9500 and is price point competitive with those CPU's. By that we mean it will perform on the same level as those CPU's at stock and overclocked speeds.

extremeoverclocking‘s review Edit

The Phenom II X4 955 & X4 945 processors are certainly a welcome addition to the AMD lineup. AMD is just starting with socket AM3 so it should be a solid investment for drop-in CPU upgrades. With the recent launch of the Radeon HD 4890 video card, and now the Phenom II X4 955 processor, AMD is pushing hard to win the hearts (and dollars) of enthusiasts and gamers. As we have seen with all the previous Phenom II processors, AMD continues to price them aggressively against competitively performing Intel chips. As we mentioned before, this chip's main competitor is the Intel Quad Core Q9550, in which our benchmarks have shown performance is extremely close... Like "photo finish" close.

pcstats‘s review Edit

AMD's Phenom II X4 955 Black Edition is an easy recommendation for anyone who's been daunted by the cost of going Core i7, and isn't doing massively multi-threaded CPU tasks like raytracing or scientific simulations. It's also an absolute no-brainer for those that already own AMD socket AM2+ motherboards and simply want to move up to a quad-core processor with more power. When under both extreme technological and financial pressure, AMD has still managed to pull off a winner with the Phenom II X4 955 Black Edition. It's one of a few very rare computer parts that gives you more value than what you paid for. Recommended.

Fudzilla‘s review Edit

With prices so low for any Phenom II, there is no reason not to consider buying one when you have to update your system. While the most efficient CPU is still the Intel Core 2 Quad 9000 series, in our opinion Phenom II X4 955 offers similar performance, especially with AMD optimized software. Also, it's much easier to overclock any Phenom II compared to Intel Core 2 Quads. Phenom II X4 955 with an overclock to a stable 3.8GHz is a great CPU for €225, and we can recommend it.

The AMD Phenom II X4 920 strikes a better balance between performance and value. We'd only recommend the X4 955 to those who want the fastest upgrade for their AM2/AM2+ PC.

motherboards‘s review Edit

The 955 Black Edition CPU is able to outperform the 810 CPU we use in platform testing across the board with higher performance. Compared to the Intel Core 2 CPUs, this CPU performs nearly as fast as a Q9650 in most situations and is therefore a great buy when paired with the $245 price tag online. This CPU also overclocks very well meaning that it is a great choice for those wanting the highest possible performance out of a new CPU.

ITreviews‘s review Edit

The first models of Phenom II were fairly competitive against Core 2 but the new Phenom II X4 955 is so much faster that it can do battle against the mighty Core i7. It loses by a fair margin but still represents very good value for money.

HEXUS‘s review Edit

Phenom13 Clocked in at 3.20GHz and able to interface with either DDR2 or DDR3 memory the AMD Phenom II X4 955 Black Edition AM3 is a good chip. AMD's new 45nm process has enabled higher clocks and the AM3 form-factor's given them a degree of additional flexibility.

TechSpot‘s review Edit

Overall we are pleased with what AMD has accomplished with the Phenom II X4 processor series, and the Phenom II X4 955 is a worthy addition to their quad-core family. While AMD may not be setting any performance records with this new processor, they are applying even more pressure to Intel’s mainstream processors, and ultimately this is good news for the consumer.

HardwareZone‘s review Edit

If there's one area where we wished the Phenom II processors would buck-up, it's their 3D performance handling where the equivalent processors still managed a decent lead. Despite that, we have to say that the Phenom II X4 955 processor has narrowed the gap between itself and the Intel processors by leaps and bounds since the first Phenom hit the streets. 3D performance aside, several other benchmarks showcase how capable the newcomer is and we really have to give it credit.

techreport.com‘s review Edit

That, I think, leads us to our conclusions, which ought to be fairly straightforward. The performance contest between the Phenom II X4 955 and the Core 2 Quad 9550 is crazy close, and even the X4 955's one apparent weakness, a higher power/thermal rating, turned out to be a non-issue in our testing.

HotHardware‘s review Edit

AMD has released some mighty interesting processors as of late. The inexpensive tri-core Phenom II X3 720 Black Edition generated quite a bit of buzz upon its release, due to its excellent value and overclockabilty. And it didn't hurt that a few weeks later news broke showing that some 720 BE processors could be modded into quad-cores with a simple BIOS tweak. The Phenom II 720 Black Edition was clearly a strong product in AMD's mainstream CPU line-up. The new Phenom II X4 955 Black Edition and X4 945, however, take things up a notch at the high-end of AMD's product stack, and like the Phenom II X3 720 Black Edition, they do so without breaking the bank.

Tom's Hardware‘s review Edit

Performance-wise, this means the Phenom II X4 955 is still an upper mid-range processor, dolled up with an unlocked clock multiplier and a platform message that bests the Core 2 Quad lineup (thanks to a strong software infrastructure supporting tweak-happy enthusiasts), yet falls short of Core i7 and its superior CrossFire/SLI ecosystem.

tweaktown‘s review Edit

As the latest addition to the AMD line-up in the Black Edition family, the 955 processor is extremely impressive. Without a huge price tag this processor is ideal for users who want to tweak and overclock their systems without having to clock buses. With unlocked multipliers this processor has enough to keep everyone happy.

www.trustedreviews.com‘s review Edit

In the Phenom II 955 Black Edition, AMD has created a great CPU that will satisfy the vast majority of power users, gamers, and enthusiasts. Most importantly, it's priced very competitively and makes for a great alternative to all of Intel's solutions at around the £200 price point. However, the apparent overclockability of these chips due to their unlocked multiplier doesn't actually hold out in normal circumstances.

AMD gives its high-end Phenom II X4 processor a speed boost, but the supporting utilities are even more interesting than the hardware.

bit-tech‘s review Edit

The bottom line is that with the Phenom II X4 955 Black Edition, like the 940, AMD has developed yet another great processor and more importantly positioned it competitively in an area that needed it. It's not the definitive choice - we still think crucially the overclocking is limited for air coolers - and in fact we still think the Intel answer is still marginally more favourable. If you don't care about an upgrade path, we feel the 940 is now the favourable AMD choice, due to the fact it has recently dropped in price quite significantly, and the overclock compared to the 955 will likely be the same.

benchmarkreviews‘s review Edit

It's definitely a welcome addition. The new chip rounds out the Dragon Platform refresh and can now take its place as AMD's new flagship processor. In addition to the 200 MHz increase over the X4 940BE, the new X4 955 also brings full AM3 and DDR3 support. Paired with a good AM3 motherboard and high bandwidth DDR3 RAM, the X4 955 outperformed the Intel Q9450 and should prove a worthy competitor for the Core i7 920 as well.
