First off on this page, the UT2003 Flyby results which are graphics card dependant more than anything else.
UT2003 Flyby performance
The graphics card is the bottle neck here so it's nice to see the 3.06 in the BT2 edging ahead of the 2.8 solution, despite having a less powerful memory subsystem. The DDR333 support on the BT2 really helps here, the observed DDR266 numbers were quite a lot lower showing just how much the processor in a P4 system likes its memory bandwidth.
UT2003 Botmatch performance
Here we are more CPU limited in the botmatch benchmark where the CPU is doing more work driving the game logic than pushing the 3D data to the graphics card during a frame render.
3.06 + BT2 with HyperThreading enabled gives us the win over the 2.8 + RDRAM solution but on the whole the DDR subsystem on the BT2 gives it a slight performance loss against the other solutions that use RDRAM. There's a nice balance of performance here depending on memory subsystem and processor used, some good scaling going on.
Onto the first of our non 3D based benchmarks, Pifast. Calculating the value of the mathematical constant Pi to 10 million decimal places puts a massive strain on your CPU and especially your memory subsystem using this version of Pifast. So how does the BT2 do?
Pifast performance
The RDRAM and highly tuned DDR controllers on the nForce2 help those systems more than the BT2. While its DDR controller on the i845PE bridge isn't exactly slow, it's one of the most efficient DDR controllers out there, it doesn't give the bandwidth needed to help it get higher in the graph of results.
Low latency DDR or RDRAM are the keys to winning a Pifast race against similar processing power, they simply give you the edge.
What about DivX encoding performance, a task where CPU and memory bandwidth are to the fore?
DivX 4.12 encoding performance
The 1.8KBit/sec encoding of the Gone In 60 Seconds first .VOB is a decent high end test of processing power and with the 3.06GHz Pentium 4 the BT2 can't best the D850EMV2 with its RDRAM memory, but it can push the 2.8 and the AMD solution to the bottom of the list and sit comfortably in second place. It's worth noticing that HyperThreading gives you a decent boost in performance.
The last page of benchmarks now.
