Intel broadwell vs haswell ULV review

Hey Guys

So I am a long time lurker first time poster

I managed to get my hands on a laptop running the new intel broadwell i7 5500 so did some benchmarks etc
Am a tad camera shy so probably not the typical charismatic youtube reviewer

Nice...So at least in ULV's broadwell is better then Haswell... That's good to know.. I wonder how the full voltage processors are going to perform...

 

What does ULV mean exactly, the above uses 0.665V at 8x, my 4700MQ uses 0.586V. I thought the "L" was supposed to stand for "Low". The core-m displayed voltages I've seen appear high as well. Perhaps they can be undervolted.



I see the 5500U appears to be able to down clock to ~500MHz. Interesting.

 

Excellent first review on Broadwell ULV, pretty nice performance jump though.

 

It stands for "Ultra low Voltage" but in reality it's more TDP limited. Something like a 15W TDP on those things.

 

The ULV processors have TDP Limit's of 15W... I'm surprised about the voltage being higher however, I'd take this wth a pinch of salt for now.. CPU-Z might not be the most accurate for reading CPU voltages and it's probably can't read these Broadwell ULV CPU voltages properly yet...

 

A 3dmark 11 test would be also very interesting to see and how it can handle faster RAM than 1600MHz. For example many Haswell ULV running at 1866MHz memory speed, but they cannot do 2133MHZ. Maybe this new Broadwell. That would definitely will bring another 5-10% extra performance

 

I don't think broadwell supports 2133Mhz.. Surprised that even 1866MHz worked...

 

I don't think it's the ULV cpus itself... it's likely the motherboards.

For example: Alienware 18 (Not M18x R1 or R2) will only support 1866MHz RAM. Anything higher does not work. My clevo, however, can do 2400MHz+. And they're using the same CPUs and same chipset. Just that Dell decided nobody needs above 1866MHz RAM so they locked it off. It's possible that ULV-using laptop manufacturers place this hard limit itself (as Haswell is reported to support 1866MHz max officially).

Broadwell would not go backwards.

 

Maybe it should have been called ULP (Ultra Low Power), not ULV.

4th Gen shown as only core-m described as to date.

 

Slightly off-topic, but looks like most laptops in 2015 will ship with USB 3.1: http://www.digitimes.com/news/a20141224PD224.html

 

What is that mean? Faster? Consumes less power? Compatible with current usb 3.0 devices?

 

Much faster, different connector. I believe adapters can be used or something to get backwards compatibility; not sure.

 

Yep, another adapter cable It also offers 12V and 20V as well as 5V with the higher voltages rated for 100W.

 

30-40% increase in graphic performance (IGP) and 20% higher clocks (+5% clock vs clock) =25% faster in CPU performance vs Haswell.
Not bad, not bad.

Too bad you didnt monitor temps of the two chips, will be interesting to see how a even smaller chip will run.
Nice little review. Those i5/i7 ULV processors wasnt expected to be revealed until CES 2015 next year. Thank you

If they run similar temps as Haswell it will be a nice little upgrade actually. But it remains to be seen how high clocked the gamer Broadwell chips are over Haswell.

 

That is good, because very difficult to plug pendrives into today's usb connectors at the back side of the televisions. Hope they will be like Apple's lightning connectors. Sorry for the offtopic, looking for more reviews on Broadwell

 

It will be a while.. This was a leak and probably Intel will make it even harder for further leaks..

 

Err, not necessarily. USB 3.1 still allows the old-style connector. The new connector is, AFAIK, optional, though the USB-IF (the specifications body) says it aims to replace small and large USB ports.

 

Thanks for the correction ikjadoon, seemed to have it in my head then were only going to use the newer connector.
