Broadwell U series HD5500 vs older dedicated graphics (HD5500 in general)

I was browsing around and noticed that there are a few more broadwell U computers coming to the market. Some of the GPU benchmarks are showing pretty high numbers for the integrated HD5500. The first comparison I made was of a Nvidia GT 720m from a dell latitude E5440 and the passmark numbers were about the same (only +20 for the Nvidia). I know that numbers on paper do not always translate to better performance in reality, but is anyone looking forward to the new version of intel's integrated graphics? Would the HD5500 actually out perform something like a Nvidia GT 720M?

 

From a 15W Broadwell IGP I'm waiting double the performance of a 720M, based on a Trinity APU back in 2012 already could outperfom an a 630M Nvidia which is about 720M.

 

Look all I know is, the Iris Pro GPU, the HD5200, is in between the GTX 460M and the GTX 560M. To think an iGPU is quickly matching the dedicated card in my laptop... it's crazy... o_o

 

I'm not overly impressed to be honest. The 460m was released 3 years prior to the Iris Pro 5200 and is bested by the 650m released about the same time by 40-50%. The Iris Pro is an overpriced and overly hot solution that nobody asked for to be quite honest.

The HD 5500 is a low performing chip, about on par with the integrated HD 4600 that's been in mobile chips since Haswell 2013. Nice to see them getting a slight bump in performance on ULV CPU's but not all that impressed still. It will likely be speed limited or TDP limited anyhow and not perform where it's supposed to which is how most of the ULV chips end up. A large part of it due to the under engineered cooling in the laptops that support these chips.

 

I would say the iris pro was released more then 3 years after the 460M but whichever way, I have to agree with what you have to say... The ULV chips are just too crippled by Intel to achieve high performance..

 

With all this being said, I would assume throttling has to come into play. With the IGPU and the low power processor working overtime, I am going to say that after 10 minutes or more games are going to have some issues. In theory, wouldn't a dedicated GPU work better if you were doing a 1 hour gaming session? Look at the surface pro 3 for example. Poor cooling and overheating basically leaves the SP3 on par with an ivy bridge HD3000 after a little while (ok I may be exaggerating a little).

 

Haswell in general was a huge failure due to becoming so freaking hot. Even my AW18 have issues sometimes cooling the chip. It can cool it, but the fan ramps up pretty high sometimes. And we are talking thickest notebook out there with a big heatsink.

Haswell U/Broadwell U could be semi good due to low TDP (15/17W). The problem however is that these chips are always used in paper thin notebooks which again means they become very hot.

 

I hear that. I used a Yoga 2 Pro to play league of legends and it ran pretty good, but man it got hot. With this next round of laptops getting even thinner, there is only so much a cpu and igpu can take.
