LAME first. This is all about FPU performance, the new bandwidth on the XP2700+ wont really help as much here, rather the raw performance of the processor.
Will XP2700+ keep up with the mighty 2.8 Pentium 4?
1 second is all that seperates the two systems and with overall time in the 196s area, that means identical real world performance. It also means that XP2800+ would be faster than 2.8 P4. Media encoding performance is important to a lot of people so that benchmark stands out for me.
Pifast, a real CPU and chipset test is up next. The memory performance increase will really show up here, XP2700+ and nForce2 should fly.
That's more like it. Low latency memory accesses at synchrous mem and front side bus clock, monsterously quick FPU are what make the grade here for XP2700+. XP2800+ would go < 70s which for an out of the box setup with no tweaking is outstanding and it's the only consumer, non-tweaked, system that would do that.
SETI and as we saw in the XP2600 review, it really flies on these new 'B' revision CPU's that are clocked high. 166MHz front side bus, sync memory clock with tight timings and 2.17GHz should see the XP2700+ put up a good fight.
That's more like it. The memory controller has a big hand in this score, along with the FPU performance. Synchronous low latency memory accesses are helping things along quite nicely and the XP2700+ CPU itself really flies doing this kind of work.
So some excellent non graphical performance from both chipset and CPU and things are looking rosier.
Lastly, another look at media encoding performance, this time encoding our Gone In Sixty Seconds .VOB using DVD2AVI, VFAPI to prepare and lastly VirtualDub and the DivX 4.12 codec to encode the data at high bitrate. The codec is SSE2 optimised in places so the P4 should beat the XP2700 here. Here's the graph.
The SSE2 optimisations in the codec help here for the P4 and it explains why it's the CPU of choice for those serious about their movies although the XP2700+ and nForce2 certainly isn't slow.
