GPU Performance

One area where Intel-based notebooks had previously was in the graphics department, and with Intel’s launch of Ice Lake they directly addressed that. Along the way, Intel has also joined AMD in more aggressively demarcating their integrated GPUs based on the price of the processor. Intel always had a small bit of variation in the included GPU, but for the most part, a Core i3, i5, or i7 U-series would generally offer the same 24 Execution Unit GPU configuration. With Ice Lake, the naming scheme now includes the GPU size in the processor name, with G1, G4, and G7 graphics options, meaning lower-priced Core i3 and i5 models will not necessarily be outfitted with the same iGPU as a Core i7.

This comes into play since Dell offers three processor options on the XPS 13, with both the Core i3 and Core i5 variants only offering the G1 graphics. To be clear, even the G1 Generation 11 graphics on Ice Lake are a larger GPU than the previous Gen 9.5 offered, with even the lowliest Core i3 featuring 32 Execution Units, but the full GPU in this laptop is only found if you choose the Core i7 model, which offers the 64 Execution Unit G7 graphics. It makes choosing the processor a bit more complex than it used to be, as it would be on an AMD-based laptop which follows the same mantra.

Dell shipped the XPS 13 review unit with the Core i7-1065G7, and as such this device does feature the full-sized GPU, and as we have seen in other Ice Lake based notebooks, the larger GPU is a significant improvement over previous designs.

In our first synthetic test, the XPS 13 finishes slightly behind other Ice Lake notebooks, but not by a wide margin.

GFXBench

GFXBench 5.0 Aztec Ruins Normal 1080p Offscreen

GFXBench 5.0 Aztec Ruins High 1440p Offscreen

We run the DirectX 12 tests from version 5 of GFXBench, and as expected, the XPS 13 scores right in the same range as expected.

Tomb Raider

Tomb Raider - Value

The original Tomb Raider has been a challenge on integrated GPUs, but with AMD’s Ryzen and Intel’s Ice Lake, the game is finally playable although without any extreme graphics settings enabled. Once again, the XPS 13 slots in right where it is expected.

Rise of the Tomb Raider

Rise of the Tomb Raider - Value

The first sequel to the re-launched Tomb Raider series is much more graphically demanding, and the XPS 13 slides out of the playability window even at the lowest settings we test at.

Strange Brigade

Strange Brigade - Value

Strange Brigade is a game with a wide-range of settings, and can be very playable even on integrated graphics. As seen with Rise of the Tomb Raider though, the XPS 13 is not quite as performant as some of the other Ice Lake notebooks we have tested.

F1 2019

F1 2019 - Value

Codemaster’s F1 simulator did not fare very well on the XPS 13, scoring well under expectations. This game can be very CPU limited as well, so TDP can be a major factor.

Far Cry 5

Far Cry 5 - Value

Like most of the other games, we see that Far Cry 5 is once again below other Ice Lake systems, but even on the best integrated system Far Cry is only barely playable regardless.

GPU Conclusion

Although the XPS 13 was outfitted with the top of the range Core i7-1065G7, with its full 64 Execution Unit GPU, the XPS 13 was not quite able to match some of the other Ice Lake systems we have seen. We will get into that a bit more in the thermals section, but this is likely due to Dell more aggressively clamping the processor to its recommended 15-Watt TDP, where other manufacturers may be more aggressive and allow 20+ Watts. Since the GPU is one area where more thermal headroom is always welcomed, this can have a larger impact than a CPU-bound task.

Otherwise, while the Ice Lake G7 GPU configuration is nothing short of a massive step up from Intel's earlier integrated GPUs, they are also competing with AMD in a field that's normally AMD's strength. So for as fast as the G7 configuration is, it and the XPS 13 end up trailing laptops based on the half-a-generation newer AMD Ryzen 4000 APUs.

    I own a XPS15 which had two main problems. Crappy Wifi chip (swap out for new Intel one, fixed) and bad cooling (can't fix, it is amazing how low my clock speeds went during gaming, buy a Ryzen 4700 Asus laptop and it is almost twice as fast because of thermals and better cooling). Mostly I want an XPS13 with AMD inside and I'll give it another shot. My $3000 XPS15 sits doing nothing, beaten by my $1500 Asus Ryzen 4000 laptop. G15.

    I looked at this, and I am very disappointed with anything soldered, means NON-upgradeable. Also lack of a separate GPU is also a problem. I am happy with my older, 15" MSI with the 7700HQ and GTX 1060. And upgradeable SATA 2.5" / m.2 drives, currently running an Adata SX8200 and a Samsung 850 Evo. I also have 2 SODIMM slots, can add another 16GB in if needed.

    My XPS13 had constant thermal problems that took months to "fix" - when I finally got rid of some Intel management software AND undervolted the CPU. At last the fan stopped cycling up and down just at idle, with the CPU at 70 degC. What a nightmare and so many hours wasted. Now I read in the comments here that undervolting is being disabled in Intel updates!

    I won't even consider another XPS13 unless it's AMD.

    I had this issue with my first-gen Infinity-Edge Broadwell XPS13. That combined with the "contrast boosting" display-dimming feature that couldn't be disabled made it useless for what I bought it for (mobile photo editing). I got rid of it in the end.

    Regarding the battery life & performance. It would be interesting to see how much you lose performance if you're running the laptop without the power cord.

    I have a somewhat bad feeling that the latest generation of laptops have a better battery life than the previous generations mainly because the laptops slow down their CPUs more than they used to.

    If we take Surface Book 2 as an example (not a new laptop but still). The CPU automatically works with lower speeds when it is unplugged. AND it is not possible to get the full speed out from the machine, no matter how you change Windows' power settings.
  • Brett Howse - Friday, July 17, 2020 - link

    That actually sounds like a good basis for an article. Windows 10 has added a lot of power management settings which can adjust the power levels of the CPU with just a slider. Can't promise anything right away but if I have time I'll look into this.

    From what kind of USB-C chargers does this charge from? Does it charge from 9V 2A PD-charger or just complains that charger is not powerful enough? How about some 20V 2A or whatever else there might be?

    Lovely chassis. Not enough to make up for the wrong CPU and the lack of a 1600p screen. I don’t want battery-sucking 4K in a 13” laptop, but I also don’t want to see pixels on my small fonts.

    There is a big problem with these devices.. The focus on thin bezels has had a negative impact on the palm rest area. It's so tiny now that the typing experience isn't very good. I suppose if you don't use it that much - it's bearable. But for heavy keyboarders ... like programmers ... I would recommend the Dell XPS 15 or 16" MacBook Pro instead. They only costs a few dollars more, but deliver a much better experience all around.
  • Spunjji - Friday, July 17, 2020 - link

    The USP of the Dell was always that it's a 13" display in a 12"-sized chassis, so the palm-rest should really be judged as such. There are a few 14"-in-13"-chassis devices out there (LG Gram 14, Matebook D, Swift 5 14) if you need more room.
