Sandy Bridge vs Lynnfiel clock for clock

post #1 of 27
Thread Starter 
I noticed a lot of people wanting to see a clock for clock comparison when the reviews were released, there is one at 2.8GHz in Hardware.fr's review, it's in French but you should be able to understand the graph (moyenne means average) :

It's called a control.

It's not 100 fps, it's 100% - anything above 100% is a gain.

English review would get more attention.
post #9 of 27
Google chrome el translator.

All you really need to know:

Before you begin testing the commercial processors in their configuration, we wanted to isolate the gains offered by Sandy Bridge (32nm quad core Core i5/i7 LGA1155) compared to the Lynnfield (quad-core 45nm Core i5/i7 1156). To do this, we have two processors clocked at 2.8 GHz, and measured the performance gap achieved. The results are presented as an index for readability.

Without HyperThreading, the gains vary between 5.6 and 20.4%, for an average of 13.2%. With hyperthreading, Sandy Bridge is 5.6 to 19.3% faster, with an average of 11.3%. Combined with the increase of frequency equal to tariff mentioned above, we can expect significant gains in price / performance ratio.

(HT review) The average gain was 7%, with up to 22% better under MinGW and Avidemux. Only Nuendo 4 and Arma 2 are especially impacted performance negatively by this technology.


That's i7 8xx @ 2.8 vs i7-2600k @ 2.8

The average gain is 2.8%.
