Intel Core i7-4790K Devil's Canyon Increases Clocks By 500 MHz, Lowers Temps

Vigile (99919) writes "Since the introduction of Intel's Ivy Bridge processors there was a subset of users that complained about the company's change of thermal interface material between the die and the heat spreader. With the release of the Core i7-4790K, Intel is moving to a polymer thermal interface material that claims to improve cooling on the Haswell architecture, along with the help of some added capacitors on the back of the CPU. Code named Devil's Canyon, this processor boosts stock clocks by 500 MHz over the i7-4770K all for the same price ($339) and lowers load temperatures as well. Unfortunately, in this first review at PC Perspective, overclocking doesn't appear to be improved much."

Speed is not the only thing.

Not everyone is limited by speed. In fact a vast majority of the users are limited by network latency and bandwidth. They will not be helped by overclocking much. Even among people running heavy duty local executables farm out graphics to GPU. So non-GPU heavy duty local apps limited by clock speed makes up for a small subset of the users and applications.

For common people video re-rendering is probably the most CPU intensive task. Even that could be farmed out to GPU, if not already pretty soon.

There are some power users in the accounting and finance department who commit crimes against software using atrociously written Excel macros. Their spreadsheet update time scales as the square or cube of the number of cells. They blame the computer for being slow and demand faster computers. Even this group does not benefit by overclocking because Excell is such a bloat, it triggers so many page faults and long (out of L1, L2, L3 cache) fetches.

So might benefit? May be people like me, doing finite element analysis, mesh generation or other such physics simulations.

For a vast majority of the users, reducing the temperature and applying it to more reliability, longer lasting, less power consuming chips would give bang for the buck. But that is difficult to test, does not garner press reports and more importantly cuts into future sales. So they will obsess with overclocking gimmicks.

I play Skyrim on a core 2 duo pegged to 30% at the moment. At 1920*1200, with a gtx460. It runs fine.

If it were actually cpu bound, it'd play like complete crap.

Didn't I read about this last week??

That was a paper launch announcement. This post is a review with benchmarks and overclocking.

Yawn
