AMD Phenom II X4 Quad Core 940 Black Edition
 
 
VERDICT
Reasonable choice for building a cost-effective quad-core system
PROS
Very good price/performance ratio
CONS
Not a patch on Intelís Core i7
COMPANY
AMD

AMDís original quad-core Phenom processors werenít very well receiving. Unfashionably late to the party and unable to keep up with even low-end Intel quad-core processors, Phenom was a brand looking for a quick death. A lot can happen in a year. AMD has been working hard over the past year. Hence, Phenom II is here. As the insertion of the ĎIIí suggests, this new processor isnít simply a new stepping, but a heavily redesigned chip. The two most notable improvements are a die shrink from 65nm to 45nm transistors (allows faster speeds while cutting power consumption), and 6MB of Level 3 cache instead of 2MB.

Major improvements include a larger L2 cache and higher core frequencies. The flagship Phenom II 940 Black Edition (Best Current Price: £199) represents AMDís high-end and clocks in at 3.0GHz. Good news is that the processor doesnít require a motherboard upgrade, unlike Intelís Core i7, which requires you to buy a new motherboard, cooler and RAM. Any socket AM2+ motherboard capable of handling a 125W processor can support all of Phenom IIís features, although a BIOS update will likely be needed. Having said that, the Phenom II doesnít support the latest super-speedy DDR3 memory (DDR2 only). AMD has plans for an upgraded Phenom II with a DDR3 memory controller later in the year. The Phenom II 940 Black Edition also doesnít have a mental feature like Intelís Core i7 Turbo Boost, but its core clock multiplier is unlocked for overclocking up to 3.6GHz (this entailed increasing the CPU multiplier from 15 to 18, and boosting the vcore from 1.336V to 1.45V).

The Phenom II X4 Quad Core 940 Black Edition is undoubtedly AMDís fastest and most overclockable Phenom yet, but itís still a million miles away from competing with Intel. While AMD canít keep up with Intel on raw performance, the company is at least keeping high-end computing within reach of mass market. As an added bonus, AMD-based 790GX motherboards are cheaper than those using Intel's X58 chipset, so you can build a quad-core system much more cheaper than an Intel-based solution. While thatís true, X58 boards generally offer more robust overclocking features, including BIOS setup programs which make life easier for seasoned tweakers. With the Phenom II X4 Quad Core 940 Black Edition you get what you pay for. If you want maximum performance and cost isnít an issue, youíll want Intelís Core i7. [7]
