Fourth representative of the Athlon II four core range, the Athlon II X4 645 adds 100 MHz to the clock in comparison to the 640. This quad-core, then, is clocked at 3.1 GHz, which is enough to see its performance level increase a little more than 1% on...

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 around...

From time to time a processor manufacturer will tweak current silicon, pushing a more stable clock speed. This is what gives us different processors speeds in the same family such as the Intel i7 and AMD Phenom II series. These tweaks, or “speed bumps...

The CPU landscape is really complex. Both AMD and Intel offer tons of different models. But how would today’s processors perform if they didn't have multiple cores? We take 16 different CPUs and compare them all using a single core running at 3 GHz. Ev...

Today we're putting the latest sub-$200 CPUs into a cage match armed with nothing but the latest DirectX 11 games (plus a helping of StarCraft 2) to see how they fare. Can AMD's familiar Athlons and Phenoms stand up to the new Sandy Bridge-based CPUs?...

For the third time in 2010, AMD is adding more speed to its processor lineup. But this time, both the Athlon II and Phenom II CPUs are being included. We spill the beans about the new dual-, triple-, quad-, and hexa-core chips in today’s article. It’s...

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 what's...

Last month, AMD released several CPUs with a slight speed-pump which also included the Athlon II X4 645. With current 3.1GHz it's the top of the L3 cacheless Propus line. All the other specifications stayed the same, with 4x256 L2 Cache, 64kB Cache for...
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...

In this review PCSTATS is testing AMD's latest mainstream quad-core chip, the 3.1GHz Athlon II X4 645 processor. Architecturally speaking the Athlon II X4 645 is identical to the preceding Athlon II X4 635 model, except for a modest clock speed increa...
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 m...

Anyone can build “the ultimate gaming PC”,with enough cash. It’s just a matter of finding the highest-end parts you can, surfing over to your favorite parts retailer’s website, and mortgaging an arm, a leg, and both kidneys. A more interesting challe...
AMD’s mantra has always been great performance at a great price, and the X4 645 certainly delivers. It delivers performance numbers mostly on par with the Intel i5 750, a CPU that retails for $200. If you’re looking to build a powerhouse gaming PC on...

If we’re honest, we’re a little bored with the top end of the CPU market. Intel’s LGA1366 socket dominates anything that AMD can throw at it and while that’s good for Intel, it’s not particularly interesting for anyone else involved.Thankfully th...
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 heartil...
