Gaming Performance

Normally on an Ultrabook we would not dedicate an entire page to gaming performance, because the integrated GPUs do not perform very well on our gaming tests. However, with this being our first example of Broadwell-U, it is a good time to revisit this and see how the new graphics capabilities of Broadwell compare to the Haswell processors.

With the Core i5-5200U in both of the XPS 13s that we received, we have 24 execution units, compared to only 20 on Haswell-U. In addition, the 14nm process should help with throttling. The FHD model (1920x1080) arrived with a two 2GB memory modules and the QHD+ version came with 2 x 4GB.

First, let's look at the synthetic benchmarks, starting with 3DMark and then moving on to GFXBench.

The 3DMark results begin to show the increased GPU performance of the Gen8 graphics. Broadwell-U outperforms all of the Haswell-U parts on all of the tests, and the QHD+ model gave a fraction more performance as well in a few tests.

GFXBench 3.0 Manhattan Offscreen 1080p

GFXBench 3.0 T-Rex Offscreen 1080p

GFXBench 3.0 Alpha Blending Offscreen 1080p

GFXBench 3.0 ALU Offscreen 1080p

GFXBench 3.0 Driver Overhead Offscreen 1080p

GFXBench 3.0 Fill Rate Offscreen 1080p

GFXBench 3.0 Render Quality (Medium)

The initial results for the new GPU look pretty good, with the new GPU soundly beating the Haswell-U parts. The HP Stream 11, with just 4 EUs, trails quite far behind. GFXBench is one of our newer benchmark choices for Windows 8, and we will add more data as we get a few more devices to test.

Next, let's look at our gaming benchmarks. Due to the low performance of the integrated GPUs, I just ran our gaming tests at the Value (1366x768 ~Medium) settings.

Bioshock Infinite - Value

GRID 2 - Value

Metro: Last Light - Value

Sleeping Dogs - Value

Tomb Raider - Value

Here we can see once again that the new GPU is certainly stronger, but it is still not quite enough to make any of these games very playable on our Value settings. The Dell XPS 15, with its discrete GPU, carries a huge lead over the integrated GPU offerings. Still, the new Gen8 Graphics with more execution units per processor, as well as a change to the architecture of each execution unit, has made a healthy improvement. The new GPU has only eight EUs per sub-slice now, as compared to ten in Haswell-U, which help in many workloads. Ian has a nice writeup on the changes.

However, our gaming benchmarks are not tested at the lowest possible settings. All of the benchmarks start at 1366x768 with medium settings, so let's drop down another notch.

Gaming Benchmarks - Lowest Settings

By setting the games to their lowest settings, some of them are now playable. We are still a long ways off of the performance of a discrete GPU, but slowly integrated graphics are improving.

Finally, we have a new gaming benchmark to add to our repertoire. Anand first used the DOTA 2 bench for the Surface Pro 3 review and it will be our go-to benchmark for devices like this without a discrete GPU. Our Value setting will be 1366x768 with all options off, low quality shadows, and medium textures. Midrange will be 1600x900 with all options enabled, medium shadows, and medium textures, and Enthusiast will be 1920x1080 with all options maxed out.

DOTA 2 Benchmarks - XPS 13 QHD+

We do not have any other comparison points at the moment, but it is very clear that a game like DOTA 2 is very playable on a device with an integrated GPU. Frame rates, even with good settings, are very reasonable.

So Broadwell has raised the stakes again, but the end result is Intel's Integrated GPU is still not going to let you play AAA titles with good frame rates. Hopefully we can get some good comparisons between Broadwell-U and the AMD APUs in the near future. It will also be interesting to see what happens on the higher wattage Broadwell parts, some of which will contain significantly more EUs.

    Seen quite a few cracked glass screens on touch enabled laptops. Some (including Dell) put a hole near the top of the glass for the microphone. Causes a weakspot near the top of the screen where folks will hold the screen to open it. Not very clever. Be wary of all glass screens. Reply

    I've had a glass-screened laptop for over a year (yoga 11s). My toddler pulled it off the table and onto the hardwood floor. Cracked the corner of the plastic case, but the screen is still intact. Reply

    Just something to be aware of. Anyone with knowledge of structural integrity etc. would avoid putting a hole in a brittle substance near to a point of frequent stress. It seems that laptop manufacturers aren't too clued up on this. The last one I got handed from a customer with a cracked touch screen took three visits from Dell to fix.

    The screens still work its just you have a nicely cracked glass layer on top. Not pretty.

    Pretty solid offering from Dell.

    I like the i5, 8GB, 256GB, QHD+ model but the price is just too high.

    The configuration that interests me is the i5, 8gb ram, 256gb ssd, FHD model which on Dells website is $1099.

    Problem is I can get a Surface Pro 3 i5, 8gb ram, 256gb ssd, QHD model for $1199.

    Dell needs to lower the prices on their models $100-$200.

    No, they don't. The improved battery life (rougly 50-200% better) of the XPS 13 alone makes up the cost difference.

    It's really an apples-to-oranges comparison, though, since tablets and ultrabooks (or laptops in general) have different strengths and weaknesses.

    Add $150 to the surface pro for keyboard. Reply

    Good point. Though $130 not $150. Reply

    Price is not too high. This is a very nice machine, and worth the money, no question.

    I'd have an i5, 8GiB, 256GB, FHD version. Stupid QHD+ eating FIVE hours of battery life, screw that, waste of time.

    The ONLY problem with the aforementioned awesome spec is... the somewhat shitty graphics. If Intel pulls their finger out, or Dell can somehow fit better graphics in the same chassis, everyone else has been utterly schooled.
