What People Are Saying Give it to me straight
Socket Type
by Tech RadarSurely the 100MHz increments provided by the multiplier are good enough for everything bar bragging rights?
by Tech RadarYou get 20 execution units as opposed to 16, but that's still half the number of the really interesting Iris and Iris Pro graphics cores that Intel is restricting to other Haswell chips.
by Tech RadarOur sources in the chip channel tell us that the new Haswell models are much more variable in terms of the speeds you can achieve with retail chips, which means most gaming systems are likely to be sold with a conservative 4.2GHz overclock at best.
Applications
by Tech RadarThe new Intel Core i5-4670K enters the CPU charts as our new favourite all-round gaming CPU.
by Tech RadarYou just can't feel 50MHz in-game and it's not going to shave significant time off a video encode job.
Performance
by Tech RadarWe're not overly distracted by the new base clock strap Intel has exposed for the K series models, either.
by Tech RadarThat leaves only clockspeeds and core counts to give them a chance of achieving a tangible performance improvement.
Power
by Tech RadarBetter power consumption is always a good thing, but the savings are tiny for grid-connected appliances.
Multiplier
by Tech RadarIt gives a bit more flexibility, allowing you to hit some intermediate speeds you can't achieve with the CPU multiplier alone.
