Chinese site posts Lynnfield CPUs benchmark results

By on August 3, 2009, 5:14 PM
We’re still about a month away from the expected launch of Intel’s Lynnfield processors, but as usual some folks seem to have gotten hold of these parts a little earlier than everybody else. Specifically, Chinese website PConline has posted a full review of two upcoming LGA-1156 parts – the Core i5 750 and Core i7 870.


As previously reported, the Core i5 750 part features clock speeds in the range of 2.66 and 3.2GHz using Turbo Boost and no Hyper-Threading. Meanwhile, the higher-end Core i7 870 will run at 2.93GHz with a top speed of 3.46GHz for individual cores and supports Hyper-Threading technology for up to eight threads. So how did they fare in the tests? A brief look shows that despite being limited to dual-channel memory and the old DMI interconnect instead of QPI, the Core i7 870 outperforms the existing Core i7 920 overall.


A screenshot of CPU-Z also shows the effect of the Turbo Boost feature which increases the frequency of the Core i7 870 to 3.2GHz. The Core i5 750 appears to be the most power-efficient of the bunch but still manages to sit between the Core i7 920 and Core 2 Quad Q9550 in terms of performance. Both chips will outclass AMD’s Phenom II X4 955, according to PConline.

Naturally, you should take these results with a grain of salt considering Intel hasn't even announced the CPUs yet, but it’s always interesting to see some numbers. The report includes benchmark results from applications such as WinRAR, Everest Ultimate and CineBench to games like Call of Duty: World at War and Far Cry 2. You can find a translated and somewhat readable version here – the graphs are pretty self-explanatory, though.

Why oh why must they keep making new sockets?! Just for once I want to take my 2 year old socket LG775 motherboard with DDR3 and 1600 MHz FSB and upgrade it to the next generation CPU! Why must Intel make CPU's faster with more pins? Why not just faster?!

Because the features that make it faster NEED more pins, but your right, intel is abusing their market dominance by creating many differently priced motherboard sockets targeted toward different market segments, unlike AM3 which is backwards compatible but also makes room for further development.

Integrated mem controller... then I guess different flavours of it. Not having done any research on it, at a guess, I'd say an i5 has a dual channel controller? i7s have triple channel hence the extra pins.

I'm not really upset at this news as its a good heads up for people looking to buy phenom cpus, watch the price drop even more. Although the article says "dont take this to heart," but we all know these surface because they really exist.. GG for Intel, and GG for future phenom purchases, you'll get your money's worth.

IMHO the need to change sockets this often is manufacturer BS.

This actually makes a lot of sense. What would the answer be if you added the 775 pins of a standard CPU with the number of pins on a North Bridge, 1366 ? (or thereabouts)

And Darth Shiv, "flavours" drives Firefox's spell checker nuts. I'd betcha "colours" would too.
