Recent tests results , obtained with the aid of dual core processors intel ( different generations ) , which work at 2.33 GHz frequency . proved that the average speed increase is limited to 5-10%, and only sometimes penryn generation processor demonstrated faster noticeable performance - in this case we deal with video coding , which is optimized by the SSE4 expansions , Intel for the first time presented this expansions simultaneously with the passage on 45 nm technology.
Today Were compared two four core processors intel LGA 775, working at the frequency 2.33 GHz. The penryn generation presented the 45 nm processor yorkfield with 1333 MHz system bus and 2 X 6 mb cache in the second level. AND the 65 nm processor was the core 2 Extreme QX6700 with 2 X 4 mb cache in the second level, which worked at 1333 MHz system bus at the frequency 2.33 GHz.
We should note that in synthetic tests the improvement in the L2 cache level from penryn generation processors result in approximately 7% performance boost. We should consider that yorkfield processors has about half larger cache volume than 65 nm processors series core 2 Quad.
From applications, which have real practical value, were used only Cinebench 10 and DivX 6.6 - average value composed 8%. The new tests of yorkfield processors will reveal their other strong (or weak) sides, but there is no miracles to expect in any event. The energy consumption level was low - The TDP level is not more than 80 W with frequency 3.0 GHz, but model with 3.16 GHz frequency will already obtain the value TDP=120 W. Related Products :
