Caged said:You really think Core 2s and Xeons perform the same? Quick, tell the world, this secret has been kept by Intel for far too long.
To buy 2x of the 2.66GHz Xeons that are in the Mac Pro would cost you nearly £800.
Pricing doesn't mean squat for performance, notice how the core 2 extreme cpus cost double the price for a 270mhz speed boost, or how the mac pro costs way more than a more powerful pc?
Core 2 Quad 6700,
Clock: 2.67Ghz
Architecture: Core
Cache: 8MiB
Core: Kentsfield
FSB: 1066MHz
Intel Xeon 5150,
Clock: 2.66Ghz
Architecture: Core
Cache: 4MiB
Core: Woodcrest
FSB: 1,333Mhz
Both use the same architecture and clock speed. And the cache balances out with 2 xeons, though if the 8MiB of cache is shared on the C2Q then that will benefit it in some cases. And of course the Xeon uses registered memory which is a minor hinderence to performance. As you can imagine, the 267Mhz fsb improvement is hardly groundbreaking. Just take a look at some benchmarks.
Just because say opterons cost more doesn't mean they perform better than athlons. They are simply named differently because they are designed for a server environment where reliability is critical and that is why they charge more, not for performance, otherwise servers would be using £50 e2140s cranked upto 3.5Ghz which would own that Xeon.
