The base model of Intel’s upcoming Core i5 600 series based on Clarkdale, the Core i5 650, clocked at 3.2 Ghz and priced at $176, has been overclocked to a dizzying 4.7 GHz on air.

The test was done on a Gigabyte P55 motherboard, cooled by Noctua NH-U12P in tandem with Coolink 120mm fan. The final result stood at 4.70 GHz (25×188). It is worth noting that the CPU overclocked was an engineering sample which had an unlocked multiplier. The actual multiplier is 24 – but even this would return 4.5 GHz, not a shabby result by any means.

The base model of Intel’s upcoming Core i5 600 series based on
Clarkdale, the Core i5 650, clocked at 3.2 Ghz and priced at $176, has
been overclocked to a dizzying 4.7 GHz on air.

The test was done on a Gigabyte P55 motherboard, cooled by Noctua
NH-U12P in tandem with Coolink 120mm fan. The final result stood at 4.70
GHz (25×188). It is worth noting that the CPU overclocked was an
engineering sample which had an unlocked multiplier. The actual
multiplier is 24 – but even this would return 4.5 GHz, not a shabby
result by any means.

Of course, this is not the first time we have seen such overclocking results – there have been numerous tests which have put Clarkdale engineering samples well over 4 Ghz. It is clear that the final retail version will be an overclocking champion. The Clarkdale Core i5/i3 CPUs will of course release on January 3rd, so we are little over two months away.

The Core i5 650 takes on the AMD Phenom II 955 at ~$175, going by the latest round of price cuts, though we can expect the Phenom II 965 to drop to $175 by the time the Core i5 650 releases. That does make for an interesting battle – 2 cores, 4 threads of the more efficient Clarkdale versus 4 native cores of the Phenom II 965.
