Broadwell ULV performance review and benchmarks

[thedavexp]

Hey Guys

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

I wish I could have done a few more performance tests because I don't think anyone else has done any benchmarks yet.

So 15W i7-5500U is 30% faster than i7-4510U in graphics? I was almost blown away since the 3DMark site says the Haswell CPU has a 28W TDP...

Core i7-5500U (2.4-3.0 GHz / 2C4T / HD Graphics 5500 / 15W TDP)
4510U HD 4400 (GT2) 15 W / 2.0 GHz 3.1 GHz
4500U 15 W / 1.8 GHz 15 W / 1.8 GHz 3.0 GHz

How did you get the Broadwell laptop? Does that mean BDW-U will launch even before March, at CES?

I think the 3dmark site is incorrect the i7 4510u is definitely a 15w TDP cpu

I do not really know how we got it to be honest I work in nz at a small retail store and for some reason HP sent us one, we had a whole lot on order but didn't expect them till 1Q 2015. So I took the opportunity to borrow one for a night and run it through its paces.

 

[thedavexp]

I can't even find any info from HP on the laptop.

30% improvement in GPU at same TDP, not too shabby. What's the memory config on those laptops?

That latter score is significantly lower than this one: http://www.3dmark.com/3dmv/5167982 GPU 3608 / CPU 9943
That means +20% on GPU and +10% on CPU.

So 20% more EUs for 20% more performance.

Which for the same TDP looks very good.

Thanks to the op, for doing the video review & showing us all the side by side comparison.. We appreciate it :thumbsup:

 

[liahos1]

question: is linear scaling not typical for synthetic benches?

 

[therealnickdanger]

Great job, thanks for the video!

 

[Arachnotronic]

Good stuff! Thanks, OP. Looking forward to the crop of Broadwell-U based systems when they hit the market.

I expect newer drivers to increase gains in GPU performance. Even so the gain is extremely mediocre. Intel needs +50% igp performance to really catch up.

Remember, this is the 15W ULV market...I'd say this is a pretty solid improvement within the same TDP.

Actually the performance is there but the drivers are not up to it.
Then remember this is a IGP with 15W TDP, shared with a CPU, so definitely you can't expect much more.

Dang this is just 82mm^2 of chip: it's fabulous it can already match 2-3 old discrete laptop cards (think low-mid range ones) and also include the processor.

It's pretty neat. I just hope that OEMs put it into good systems that make the correct user experience focused trade offs.

The OEMs need to drop the super high resolution panels (esp. since Windows DPI scaling is pretty bad) which drain battery life as well as the crazy obsession with paper-thin, and instead focus on better touch pads, sturdier industrial design, and higher quality displays (color, viewing angles, etc.)

The process power reduction should allow for 50% gains on the GPU. I'm not seeing this so either BW is using much less power or something else is happening.

20% with node shrink at the same TDP is downright pathetic.

 

[Arachnotronic]

What I found interesting was the big boost in 3DMark Physics score (CPU perf) even with the base frequencies/IPC relative to the Haswell processor not up all that much.

Intel seems to be using the 14nm transistors to keep clocks to the same but to allow for higher average performance in a thermally constrained envelope. Smart.

Yep OEM choices matter more than the single part now, I'm looking at Broadwell-Y and whoever choose to put a 4K display with it... just use a good quality 1080P, even the new power saving variant (I dont remember the name at all) would be great for a premium price.

I am baffled too by the weird CPU increase: mostly base clocks gains, big ones, but looking thorough the charts there are also decreases in max turbo sometimes...
Then the new 5y71 chip even has a 2.9GHz turbo in a 4.5W TDP so I'm really speechless when a 15W part is limited to 3ish or a few bins more.

Maybe it's all marketing and they (Intel) are going to release much better variants in the future?
Stress tests shoud give a better picture: just think how long they could keep those turbo speed up vs the much more limited -y variant.

I'm more interested to see battery life.

Haswell was pretty good in 3dmark but often failed in games. So having a 34% better Vantage GPU score and overall P5100 is a nice result for a 15W CPU, I would expect that in real games the increase can be 50% over Haswell.

The implication of this being that you believe Broadwell's changes will be more meaningful for real world performance than Haswell's?

 

[AtenRa]

What Memory did the BW laptop used ?? 1600MHz or higher ??

Yes of course. There was a big deficit from 3dmark or Computing to real gaming performance in the past, one reason could be the poor texturing performance. Intel improved it for Broadwell. Should help for MSAA as well.

Thanks!
Feel free to post new numbers, people have been starving for this.
