Dell XPS 15 (L501X): Intel Core i7 840QM/2GB nVidia GT435m Review

Unigine provides an interesting way to test hardware. It can be easily adapted to various projects due to its elaborated software design and flexible toolset. A lot of their customers claim that they have never seen such extremely-effective code, which is so easy to understand.

Heaven Benchmark is a DirectX 11 GPU benchmark based on advanced Unigine engine from Unigine Corp. It reveals the enchanting magic of floating islands with a tiny village hidden in the cloudy skies. Interactive mode provides emerging experience of exploring the intricate world of steampunk.

Efficient and well-architected framework makes Unigine highly scalable:

  • Multiple API (DirectX 9 / DirectX 10 / DirectX 11 / OpenGL) render
  • Cross-platform: MS Windows (XP, Vista, Windows 7) / Linux
  • Full support of 32bit and 64bit systems
  • Multicore CPU support
  • Little / big endian support (ready for game consoles)
  • Powerful C++ API
  • Comprehensive performance profiling system
  • Flexible XML-based data structures

We test at 1080p so that all video cards can be compared throughout our reviews. Obviously driver updates might enhance performance slightly over time, but as a rule, its a useful way for us to present the findings. 1080p is also the native resolution of the screen in our Dell XPS 15 sample.

The nVidia GT435m struggles at these settings with this demanding tessellation heavy engine.

  1. That really is a fucking sweet laptop. even without the bluray and dropping down a CPU, its under a grand. t hat is excellent.

  2. Always great when I get a new Kitguru review alert on Twitter 🙂 awesome review man and that is a hell of a good looking machine. I am not sure im sold on the appearance, that two tone thing looks a bit messy, id prefer it was darker, like the front, but I suppose you arent looking at the underside much. the intel core i7 cpu is great.

  3. Wow that Intel QM CPU blows me away

  4. Well what a great stoke of luck. I was looking at this machine on christmas eve and didnt know if it was going to suck. ill aim for a lower specification than this, but I need a new laptop for 2011 for work, and ill bill it to the company (just need to keep it realistic).

  5. Excellent, I like the skins, some really cool looking ones

  6. njice to see dell reviews here, only thing I will say is that I have had a terrible time with dell batteries failing after 18 months to 2 years time. Not sure if it has been a batch, but google shows quite a few people seeing the same thing.

  7. excellent machine, I just bought an Acer for £500 quid in PCWORLD though :p

  8. Great machine, however, Dell took away the 1080P screen option though! Hopefully dell will have that option back soon, or else the CPU and the GPU will be wasted! (This option is back in other country except for the US)

  9. They actually arent selling the 1080p machine in the UK either? what happened?

  10. I think the 1080p machine is available in parts of europe now, but it might be due to 1080p screen demands and lack of stock. very unusual to pull a system mid range though.

  11. The 1080p option will be back at some stage. Dell said this “We still offer the screen but had to temporarily take it offline as our supplier had to de-commit on certain quantities. It can still be ordered over the phone if one doesn’t mind an extended lead time. “

  12. The 1080p option is back in Canada

  13. Conservative design in my opinion, and it’s even kinda of thick for laptops nowadays.
