ATI Catalyst 3.2 Video Card Drivers
As predicted here we see the P4 3GHz "C" chip doing very well. Even with the 3GHz "C" chip no HT Enabled against the 2.4B clocked @3GHz, the 3GHz "C" chip pulls ahead in Dhrystone ALU probably due to the added FSB bandwidth. Although we don't see significant increases in all areas until HT is kicked in and even further when we bump up the CPU speed to 3.5GHz. For the first time since the introduction of the AMD AthlonXP line of CPU's we are seeing an Intel CPU that will not only compete, but blow by the competition. Also, when SSE comes into play things only get better.
We continue to see great performance from the 3.0C and enabling HT pushes the envelope even further. What's really great here, as that not only do you get good performance from the CPU, but with HT enabled we see a significant increase in overall performance. Can you say "free processing horsepower"? As I suspected, the P4 2.4B/533 keeps up rather well to the 3.0C/800 at an equal clock and no HT enabled on the "C" chip. Once we kick in HT it's an entirely different story however. In float performance, we are seeing a 45% increase in performance with HT enabled. That's incredible! Integer performance is seeing a 16% increase. Not too shabby either.
SiSoft Sandra Memory
The trend continues and we are seeing some killer memory performance out of the 3.0C/800 CPU. Notice no change between the 3.0C with and w/out HT enabled which is expected of course since there is no actual clock or bandwidth increase. Once we move up to 3.5GHz however, memory bandwidth is extremely impressive. Who am I kidding? It's impressive at 3GHz!!
