Energy-Efficient Sandy Bridge: Intel Core i5-2400S CPU Review
The whole point of integrating a GPU into the CPU is so that it can be much more powerful, because TDP isn't a problem, unlike with chipsets.
Unfortunately Intel's GPU is terrible, and Ivy Bridge won't change that. They should've included a powerful GPU with just the dual core CPUs.
In a few months Fusion comes out, and it'll completely outclass Intel. Sure they CPU won't be that powerful, but the GPU will be amazing (compared to other integrated solutions). That's exactly what an APU should look like.
Please could you compare real energy consumption of the 2400 and 2400S CPU required to accomplish certain task? For example run a CPU-intensive task (like MP3 encoding, video encoding, file compression), measure the power consumption during the task and then integrate it over time to get the total consumed energy (in Joules).
The instantaneous power consumption of 2400S would be lower but as the task would require more time to accomplish the total energy consumption could be very similar on both processors.
Ergo, the S version is pointless
