AMD Phenom II X2 550 Black Edition 3.1 GHz Socket AM3 Processor Review

AMD Phenom II X2 550 Black Edition 3.1 GHz Socket AM3 Processor Review - PCSTATS
Abstract: AMD's suggested retail price for the Phenom II X2 550 processor is a mere $103 USD ($110 CDN, £62 GBP), which positions it right between Intel's 2.6GHz E5300 processor and the Core 2 Duo 2.8GHz E7400 processor. This makes it both an inexpensive, easy upgrade for those looking to drop it into an existing socket AM2+ motherboard. The 3.1GHz clockspeed and potential overclocking headroom....

CPU Calculation Benchmarks: Super Pi, wPrime2.0, ScienceMark2, WinRAR

Super Pi Mod 1.5 Source: SuperPI

SuperPI calculates the number PI to 1 Million digits in this raw number crunching benchmark. The benchmark is fairly diverse and allows the user to change the number of digits of PI that can be calculated from 16 Thousand to 32 Million. The benchmark, which uses 19 iterations in the test, is set 1 Million digits.

Lower calculation times are better. SuperPi is not multi-threaded.

The higher clock speeds of the Phenom II X2 550 Black Edition give it a good win against the Phenom II X3 720 Black edition, however the reliance on a large L3 cache doesn't work well for AMD in this single-threaded test, where faster L2 memory and higher clock speeds help the Core 2 Duo processors finish faster.

wPrime 2.0 Source: WPrime

wPrime uses a recursive call of Newton's method for estimating functions, with f(x)=x2-k, where k is the number we're sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.

Lower calculation times are better. wPrime is multi-threaded.

This multi-threaded benchmark actually has the dual-core Phenom II X2 550 Black Edition faster than the dual-core Core 2 Duos. However for any work like this you really do need a quad-core processor, which can effectively half the amount of calculation time.

ScienceMark 2.3 Source: ScienceMark

Mol Dyn: Molecular Dynamics is a method for simulating the thermodynamic behaviour of materials using their forces, velocities, and positions. Most important of the afore mentioned is the force. Primordia: This code calculates the Quantum Mechanical Hartree-Fock Orbital for each electron in any element of the periodic table lower times indicate better results.

Lower calculation times are better.

AMD Phenom II X2 550 Black Edition 50.63983

ScienceMark's results have always been a little strange. The Primordia test seems to be very sensitive to pure clock speeds, with the fastest processors being the 3.2GHz 955BE and the 3.16Ghz E8500, with the 3.1GHz Phenom II X2 550 Black Edition in third place.

The Mol Dyn benchmark seems to appreciate bandwidth and memory efficiency a little more, which puts the Phenom II X2 550 Black Edition behind everything but the tri-core 720BE.

WinRAR Internal Benchmark Source: RARLabs

This command generates random data, which contain specially introduced redundancy increasing load to processor and memory. Then data are passed through RAR compression and decompression algorithms and output of decompression algorithm is compared with source data. If any difference found, WinRAR reports "Errors found - Yes" in the command window. Also WinRAR displays a size of processed data and compression speed, current and resulting, in kilobytes per second. You may use the resulting speed value to compare RAR performance in different conditions.

Higher results are better.

WinRAR's internal benchmark is multi-threaded, so the more cores it can access the better. Strangely, the E8400 has actually beaten its bigger brother, with the Phenom II X2 550 Black Edition right in between the two.
