Last month, AMD became the first company to bring a $99 quad-core processor to market, the Athlon II X4 620. The question, of course, is whether or not it delivers. At 2.60GHz, it looks to offer ample performance, but the lack of an L3 cache is sure to be seen in some of our tests. Luckily, the chip’s overclocking-ability helps negate that issue.
Autodesk’s 3ds Max is without question an industry standard when it comes to 3D modeling and animation, with DreamWorks, BioWare and Blizzard Entertainment being a few of its notable users. It’s a multi-threaded application that’s designed to be right at home on multi-core and multi-processor workstations or render farms, so it easily tasks even the biggest system we can currently throw at it.
For our testing, we use two project files that are designed to last long enough to find any weakness in our setup and also allows us to find a result that’s easily comparable between both motherboards and processors. The first project is a dog model included on recent 3ds Max DVD’s, which we infused with some Techgage flavor.
Our second project is a Bathroom scene that makes heavy use of ray tracing. Like the dog model, this one is also included with the application’s sample files DVD. The dog is rendered at an 1100×825 resolution, while the Bathroom is rendered as 1080p (1920×1080).
What a nice way to kick things off… with AMD’s $99 quad coming ahead of Intel’s $150 quad. It’s also interesting to note that the X4 620 pulled ahead of the X3 720 Black Edition as well. This might be a popular theme throughout the review, as although the X3 720 has a faster clock speed, it lacks the fourth core.
Like 3DS Max, Cinema 4D is another popular cross-platform 3D graphics application that’s used by new users and experts alike. Its creators, Maxon, are well aware that their users are interested in huge computers to speed up rendering times, which is one reason why they released Cinebench to the public.
Cinebench R10 is based on the Cinema 4D engine and the test consists of rendering a high-resolution model of a motorcycle and gives a score at the end. Like most other 3D applications on the market, Cinebench will take advantage of as many cores as you can throw at it.
Compared to the Core 2 Quad Q8200, the Athlon II X4 620′s dominance didn’t last too long. But, it’s hard to discredit the lowly quad in this case. It proved just 2% slower, but costs 33% less.
Similar to Cinebench, the “Persistence of Vision Ray Tracer” is as you’d expect, a ray tracing application that also happens to be cross-platform. It allows you to take your environment and models and apply a ray tracing algorithm, based on a script you either write yourself or borrow from others. It’s a free application and has become a standard in the ray tracing community and some of the results that can be seen are completely mind-blowing.
The official version of POV-Ray is 3.6, but the 3.7 beta unlocks the ability to take full advantage of a multi-core processor, which is why we use it in our testing. Applying ray tracing algorithms can be extremely system intensive, so this is one area where multi-core processors will be of true benefit.
For our test, we run the built-in benchmark, which delivers a simple score (Pixels-Per-Second) the the end. The higher, the better. If one score is twice another, it does literally mean it rendered twice as fast.
In the case of POV-Ray, raw frequency plays a huge role in overall performance, and that’s proven here when once again comparing the X4 620 to the Q8200. We’re off to a great start, so let’s move right into our other multi-media tests, including Adobe Lightroom and TMPGEnc Xpress.
