Intel i7 4710MQ vs 4700MQ - there seems to be a huge difference...

... based on CPU Boss info. It reports that Intel i7 4700MQ supports 1333Mhz RAM and 1600Mhz RAM and has max bandwidth of 25,600MB/sec while 4710MQ only supports low profile 1333Mhz RAM and has max bandwidth of 12,800MB/sec. Here, take a look for yourself - http://cpuboss.com/cpus/Intel-Core-i7-4710MQ-vs-Intel-Core-i7-4700MQ .

Is that true or not? That bandwidth difference is HUGE. Dual channel 1600Mhz DDR3 undeniably runs above 12,800MB/sec! Yet, if 4710MQ does not support 1600Mhz and only 1333Mhz, then it could be the case I guess... But why going backwards in bandwidth? Why does Clevo/Sager include only 1600Mhz RAM in their configurations that use 4710MQ or 4810MQ CPU's? If all they can do is 1333Mhz DDR3, then using 1600Mhz is overkill. This all smells BS. 4710HQ and MQ CPU's are laptop counter-parts for 4790K and similar CPU's, which support RAM speed up to 2400Mhz, not 1333Mhz. Is CPU Boss simply messed up? Shall we gather, march, and rally to expose their falsehood and lack of indeedness as words smooth out of their conversing mouths and finger dee-dee's?

Also, it shows that the 4710MQ supports 2 new extensions - FMA3 and EMT64T, neither of which are supported by 4700MQ. Do either of those extensions or could either of them affect game performance? I know ultimately its the speed, cache, etc., but sometimes certain extensions actually do make a difference in framerate or even features. Are either of those features like that???

 

Rule of thumb, do not trust CPU Boss.

Secondly, a quick look at Intel ARK would show you that the 4710MQ also has the same bandwidth - http://ark.intel.com/products/78931/Intel-Core-i7-4710MQ-Processor-6M-Cache-up-to-3_50-GHz.

Thirdly, the 4710MQ is basically a higher clocked 4700MQ as suggested by the name.

 

Basically the 4710 to the 4700 is like the 4720 to the 4710. They are physically the same chip (give or take a little maybe), but as intel's yields improve over time the chips can maintain a higher stable threshold level and they peg it 100mhz or so higher and rename it, then call it a new product.
In practice though, the 4700, 4710, 4720 shouldnt have too much difference between them in day to day use. Benchmarking is probably the only place where you find a distinctive divide in performance if any.

 

There's none, I've had 4710 and 4720, for all practical purposes, no difference ......

 

Haha i stand corrected then, performance is the same as they are literally for all intents and purposes basically the same chip.

 

Not many places where you'll even notice a measly +100 MHz when they're all clocked well above 3 GHz these days
