Rendering and Encoding Tests
Next up are the rendering and encoding tests.
For this, we are going to look at Cinebench, POV-Ray, and
Cinebench 10 is a very well known rendering
benchmark that can utilize a single CPU, multiple CPUs, or even
GPUs. For this test, we used Cinebench 10 64-bit, looking at
both single threaded and multi-threaded performance. Higher
scores are better.
In the single threaded test, clock speed and
architecture are all that matter, and in this test the stock 965
handily beats out the competition. However, when overclocked,
the x3360 again takes the lead.
For the multithreaded test, the dual and triple
cores move to the bottom, leaving the x3360, 965 and 955 alone at
the top. The 965 again tops all of the stock CPUs, but loses
to the x3360 when overclocked. For whatever reason, the 955 at the
same clock speed also took a bit of a lead here, too. Why this
is the case is not clear.
POV-Ray is another popular rendering benchmark
that also supports both single and multiple threads. Test
results are measured in Pixels Per Second, and a higher score is
better. For this test, we used version 3.7 beta 29.
The PovRay test seems to favor the AMD
architecture a little better than Cinebench does, and it shows here
as the 965 takes a pretty substantial lead over the E8400 and x3360
at stock speeds. When overclocked, the 955 actually still
beats out the 965, while the overclocked x3360 still is the top dog.
In the multithreaded test, the 965 again places as
the top stock CPU, and sits directly behind the x3360 and 955 at the
X.264 Encoding Test
Finally, we have the X.264 encoding test. In
this test, a small video file is encoded into the H.264 format.
There are 5 runs that get two passes each; since each run typically
performs identically to the other 4, we are just going to report
both passes of the first run. Higher scores are better.
In the first test, the stock 965 really outshines all other stock
CPUs, while falling just under the 955 for the overclocked category.
In the second test, the 965 again takes the crown as the fastest CPU
at stock, but is again beat out by the x3360 when overclocked.
