AMD Phenom X3 8750

AMD have released the revolutionary triple-core processor with three models available that include the AMD Phenom X3 8450, X3 8650 and X3 8750 (this review) which supports the latest B3 stepping technology. Like the QUAD core Phenom processors, the triple core processors incorporates three cores onto a single die of silicon, ensuring the best for multimedia, multitasking and gaming.

In relation to the AMD Phenom X3 8750 processor, it runs at a whopping 2.4Ghz and is manufactured with 65nm Silicon on Insulator process technology. Best of all, this processor has been designed to be energy efficient which still allows for high-end performance but with controlled energy dispersion. Add in 3MB of combined L2 and L3 cache, the AMD Phenom X3 8750 is no slouch when it comes to power.

We tested the processor with Sandra WI SP2 Memory Bandwidth benchmarking and discovered some startling results that performed also as well the AMD Phenom 9850 and better than the Intel QX9770 in this aspect proving that the CPU has the ability to move large amounts of information around in flawless perfection.

In regards to real world software such as Windows XP, CS3 Photoshop and Microsoft Office 2008, the CPU performed well, however was not as powerful as the Intel based CPU's but in regards to multitasking, it performed exceptionally well, given the cost and power of the higher end Intel processors.

Gaming is a real test for a CPU, considering the power that it uses to create vast gaming worlds as its renders graphics, calculates artificial intelligence and a wide gamut of other options, it can sometimes be considered a definitive test for the CPU.

We tested the game with Crysis and medium resolution and detail which produced an exceptional 30 frames per second which is quite impressive for this game that struggles on even the high end Intel systems.  Crysis is a first person shooter that requires a considerable amount of CPU and graphic processing power and to be able to run the game at this speed is a true test for this processor. BioShock performed equally well as did World of Warcraft.


In conclusion, the AMD Phenom X3 8750 Triple Core Processor worked quite with a variety of applications and games with no issues whatsoever. As developers continue their support of multiple cored processors such as dual, quad or triple core, these are definitely the CPU's of the future that not only improve performance, they reduce energy consumption and allow the user access to a greater number of software opportunities.

One of the best aspects of the X3 8750 is the ability to install the CPU into almost all AM2 boards without any hassles whatsoever which is a huge advantaged over Intel which require new motherboards. With the inclusion of B3 stepping, this processor produces quite a few benefits to the user with a stable operating system and decent performance.
