Running HD Tune 2.55, I came up with the following numbers.
500GB, 16MB cache, 7200.10 (3 platter design)
65 MB/sec average transfer rate, 15.1 ms Access Time, 34°C Temp
500GB, 16MB cache, 7200.12 (1 platter design)
104 MB/sec average transfer rate, 15.8 ms Access Time, 28°C
To put the 7200.12 500GB numbers in perspective, my 300GB WD Velociraptor has these specs (granted the Velociraptor is my boot drive, so Vista is accessing it quite a bit more than it is the Seagate drives, which only contain my game installs):
94 MB/sec, 7.3 ms Access Time, 31°C
I still feel the much lower access time of the Velociraptor is worth it for a boot drive, since the OS and productivity programs will get a nice speed boost, but for large sequential reads (e.g. loading games) the throughput of the 7200.12 is awesome! Not to mention it is about $150 cheaper than the Velociraptor.
Edit: For another interesting comparison, I have a 1TB 7200.11 drive, which has a 32MB cache and also contains 3 platters, but it has higher data density per platter than my 7200.10 500GB drive. The benchmarks for this drive are...
