AMDs Effect of a Cacheless Northbridge – Page 3

  I honestly tried to get very accurate results, but like I mentioned earlier a couple benches like 7-Zip made it hard to do. Also, Instead of providing peak numbers for the benches I picked the result that was the most common. Anyways, check out the results below for each program I used as a benchmark.


  SuperPI Mod1.5 XS


This is a Very popular bench application thats more sensitive to cache than the memory subsystem in general. I decided to use a 1 MB chunk since that is definitely the most popular size. Whats nice about the mod version of SuperPI is that it includes milli-second results instead of just providing second’s based results that the non-mod version uses.
As you can see, there is a consistant increase in performance. Although its approx a 4% increase from top to bottom..


  Fritz Chess Bench 4.2


This is another bench that is somewhat popular. It is actually based on an engine used in Chess software.



Not to much going on here. A small increase is all you get. About a 4% increase from top to bottom.




A well known bench program based on the actual game itself. Although not used as often now, it used to be a very popular benchmark in the past. The bench provides Graphics, CPU, and Total results.



The increase here is alittle more noticable than the previous benches. The CPU score rises nearly 8% from top to bottom while the Total score gets a solid 6% increase.


  Cinebech R10 32 Bit


This is a popular bench that can put a hurting on the cpu. It makes a great stability test as it will try to use every core it can to the full.


Whats interesting here is that the CPU benches only got alittle more than 3% of a increase. But got a big increase of almost 15% from top to bottom when it comes to the OpenGL rendering. The increase from 2256 mhz to 2820 mhz is very small and may be do to memory throughput being low. You should expect larger gains in connection with faster clock speed ram.
