The PS4 CPU will be comparable to an i7 only if the game tested uses the 8 cores, in a standard PC these would have about the same IPC as a pentium for dual-core tasks

The reviewer compared it to Ivy Bridge i5 clock to clock performance or IPC, so if an i5 was downclocked at 1Ghz you would see the same performance in benchmarks without Intel CPU using hyperthreading for fair comparison 4 cores 4 threads vs 4 cores 4 threads.

i7 3770k in total has 14Ghz of raw performance and PlayStation 4 will have 12.8 to 16Ghz depending if its clocked at 1.6 or 2.0Ghz, developers will use all 8 cores and we already saw that FX 8350 beat i5 3570k in Crysis 3 by a considerable margin. Imagine if Steamroller has 30% IPC over Piledriver, it would demolish Ivy Bridge and Haswell in Crysis 3 and soon Crysis 4.

Is this real life?

Make the battery/screen a tiny bit better (say, options for 1600x900/an attachable battery), and this is literally a perfect student (non-gaming) laptop.

Most students like me just use laptops for work, and do gaming on consoles (or desktops). Kabini will give me better battery life than an intel chip anyway... WANT.


EDIT: Does this have a replaceable SSD?

in comparison terms, a .4 ghz overclock increased cinebench cpu performance by +45% and graphics score by +21%. So assuming that the statement saying that the cpu is about a third of a performance of a ivy i5 in cpu performance is pretty accurate, an Intel Core i5-3337U 1.8GHz can go up to 2.7 in ghz on turbo mode. rounding the performance gain in a linear fashion, if the temash magically went up to 2.7(1.7 above base clock), a 1.6 ghz overclock would result in a +180% increase in performance, so linearly the 1/3 power of ultrabook ivy i5 is semi realistic. Though of course overclocking gains aren't linear so there will eventually be a drop off point in performance gain per clock.

Looks nice. I'm waiting for something 13'' with 25w kabini in it.

"He also ran a few benchmarks and concludes that the laptop offers about a third the CPU performance of an Intel Core i5 Ivy Bridge processor and about the same kind of graphics performance you’d expect from a Sandy Bridge chip".

 

you all can talk about price/performance all you want, but there's  limit to how much performance you can sacrifice.  I have an Asus zenbook with a i5-3317U.  It's typically clocked at 1.7ghz and runs windows 7.  If I drop the clock speed by half, and run it at 850mhz, it's still faster than this AMD 1ghz CPU. However, I rarely drop the clock that low because the performance is terrible.  Loses all of it's "zippyness" 

 

Saying "oh but the wattage!"  Well look at those old brick phones, they last for days! Nobody cares though because you can't get the same experience on a brick phone as you would on a SG4.  

 

but "oh but the GPU!" What're you running?  Same kind of GPU performance as the iGPU on a sandybridge?  Is that supposed to be a badge of honor?  These are for windows 8 right?  What x86 game runs well on a HD2000?  Nothing recent.  

 

Lastly, the GPU performance, regardless of perf/watt is not some sort of saving grace.   CPU speed is what's going to drive your daily tasks.  As far as I can see, the CPU is lacking...heavily.  And this "but you can plug it into a wall for performance!"  Good for you, buy a desktop.  

 

Great performance per watt, just not enough performance yet.  Simple as that.
