What is the max. safe temperature for the SPP?
There isn't that much difference between those 2 (only 3°C)
@ 3510 (9x390MHz) and mem @ 866.7, SPP is max 60°C @ 1.4v
@ 3480 (8x435MHz) and mem @ 870, SPP is max 63°C @1.55v
As for the benchmarks:
@ 3510: No increase to CPU score (Zlib score 0.002% more than @ 3480)
@ 3480: Enormous increase in memory score (+12% compared to 3510
, and synching memory to a 1:1 ratio @ 3510 will increase read performance, but decrease write and copy performance, as the latency stays just about the same
)
@ 3510: I have to increase the vCore to 1.525 to get it stable compared to the 1.49375 I use @ 3480 (This increases the temperature of the CPU with 5°C idle and 10°C in full load)
@ 3480: I have to increase vFSB to 1.5v compared to 1.4v @ 3510
So the higher bus speed is faster in overall performance, and the biggest difference is only noticeable in the RAM.
