Intel Core i5 (mainstream Nehalem) benchmarks

Now the high-end Core i7 has been officially launch, Intel is working on the introduction of its mainstream Nehalem processor (codename Lynnfield). It's expected that the Lynnfield will be released in the third quarter of 2009, bearing an American recommended price of under 200 dollar. Chiphell has posted the first screenshots of alleged benchmarks, reached with an ES sample of this quadcore.

All benchmark screenshots contain this CPU-Z screen which identifies the CPU as a Lynnfield with a 2.13 GHz frequency. De processor has 256 kB L2 cache per core and 8 MB of shared L3 cache.

The screenshot shows that the mainstream Nehalem will be branded Core i5. The LGA1156 socket is identified by the infotool as LGA1160. This was allegedly the old name, before Intel decided to remove four pins from the specification. The images also show that the used test setup used 6 GB of dual-channel PC3-8500 DDR3 memory, combined with an nVidia Quadro NVS 290 graphics card. The motherboard could not be identified by CPU-Z. 

The results of the five benchmarks can be found below, being SuperPI 1M, Cinebench R10, FritzChess, wPrim2 and 3DMark Vantage. 

The tested Core i5 calculates pi to a million decimals in just over 19 seconds. To compare: the high-end Core i7 940 (2.93 GHz) does it in 5.5 seconds less with dual or triple channel memory. 

The Core i5 reached a single-core score of 3134 in Cinebench R10, as well as a multi-core score of 12523. A Core i7 940 reached scores of respectively 3428 and 14252.

FritzChess calculates 7784k nodes per second, over 16 times as much as a Pentium III 1.0 GHz. The program recognizes eight "processors" because the Lynnfield quadcore uses HyperThreading. 

wPrime numerically calculates the root of a large amount of numbers. The Core i5 took 11.42 seconds to process 32M and 352.2 seconds to do 1024M.  

3DMark Vantage showed a CPU score of 13271.  The Core i7 920 reached 18525.
