ASUS A8N32-SLI Deluxe Motherboard - Full Speed SLI *Exclusive* - Benchmarks - CPU Overclocking

When nVidia first launched their dual graphics platform, it initially come under some scrutiny for only offering two 8x PCI-E ports. Many months later nVidia announced their nForce 4 SLI X16 chipset which offers two full speed PCI-E slots, each with 16 lanes. Today we've got a very exclusive look at the ASUS A8N32-SLI Deluxe motherboard. We closely examine the performance of the two different PCI Express port lane configurations to determine if it's actually worth upgrading to the new chipset or not!

CPU Overclocking

 

Even with the power of the AMD Athlon X2 and Intel Extreme Edition processors, we still find ourselves hitting a CPU limitation in a lot of our benchmarks. That is, the graphics cards have more performance to give but the processor is letting the team down.

 

By overclocking the processor we can see what kind of a performance increase we get. When something isn't CPU limited the performance increase isn't all that major but when we do have a CPU bottleneck, every MHz extra we can get can show us an excellent jump in performance.

 

The Athlon X2 3800+ was increased from 2GHz to 2.35GHz with a slight increase in the front side bus utilizing the stock X2 HSF.

 

While we don't call our 350MHz jump in speed a huge overclock, it is worth nothing that the A8N32-SLI Deluxe had no problems doing it which is good to know as we did wonder if the extra chip on the motherboard was going to hinder our overclock - which it didn't.

 

 

3DMark03 again shows the X16 behind the previous chipset by a few hundred points.

 

 

Both resolutions show the newer chipset being a little slower then the original nForce 4 SLI.

 

 

It seems that with the processor overclocked to 2.35GHz in our CPU limited benchmark we again see the x16 chipset lagging behind.
