A quad-core CPU that offers performance levels at times lower than dual core models. It is nevertheless a good performer in applications that are adapted to the use of several...

A quad-core chip on the cheap is a compelling concept. The new 3.1GHz AMD Athlon II X4 645 is certainly a quad-core chip, but is it cheap enough at £95?For sure, there are more affordable Athlon II X4s on offer. The 2.6GHz 620 model can be had for...

The X4 645 struggles to carve out a place for itself in the market. It's only averagely fast in single-threaded applications as, despite its high clock speed, it’s still based on an old architecture. For a cheap gaming rig or image editing PC we’d...

Like it's predecessors, AMD's 3.1GHz Athlon II X4 645 is an ideal computer processor for those who need good multi-threaded application performance, but have to live within the reality of a tight budget. This chip costs $122USD, making it one of the...

As was evidenced by our test results, the Athlon-II X4-645 offers great performance for its price range. It competing very closely with processors costing a lot more. The most important thing, however, is just the simple fact that it can get the job...

Looking back at the performance graphs, Athlon II X4 645 performed as expected in every way, both good and bad, and even throwing a few pleasant surprises along the way. Strong points for this processor are by far its reasonable price, and fast four...

Benchmarking 86 CPUs takes a while. After long last, though, we have 51 models from AMD and 35 from Intel tested in our current suite. If you want to know how your processor sizes up to its competition, you'll find plenty of comparison data inside! 86...

This time we'd like to offer you the summarized test results of as many as 71 processors. This generally marks the end of the year, not the end of another test method's life cycle (like the last time). We believe this summary contains all important...

Although we've tested most processors from Intel, no due attention has been paid to a lot of CPUs from AMD. Today we shall make amends and examine as many as five affordable processors from this company. Testbeds Today's lineup to test will include...

The overall score quite precisely describes processor standings which marketing specialists could have in mind when setting prices. So, formally, we can say that every processor is in its place and is worth buyers' attention. Although, considering architectural differences, you should choose...

We are not very fond of the 100/133MHz increases of any manufacture on any CPU. It's quite senseless to increase the frequency so little in the 3GHz age, because it does not make much difference, besides the money the companies will cash it for. AMD...

AMD recently refreshed their Phenom II and Athlon II lines with six new processors. Of course it wouldn’t be any fun to just tell you about new processors without showing off what they can do, now would it? We didn’t think so either, so today we’re...
