Average Performance, Efficiency, And Value
Xotic PC promised us better gaming performance at a lower price compared to its competition. We were the ones to specifically ask for the same CPU and SSD so we could focus on comparing AMD's and Nvidia's current-gen graphics modules. The crew at Xotic PC did (wisely) add a fourth memory module, however, and that change slightly boosts the performance of our encoding and productivity applications.
A huge speed-up in gaming performance will be partially reduced in our efficiency chart, since that measurement uses the average of all benchmarks and power tests.
Since the previous GeForce GTX 675M-equipped configuration set the performance mark that Xotic PC was hoping to beat, we also used it as the basis of our efficiency evaluation. An average performance gain of 11% combines with an average power savings of 6% to give Xotic PC an average efficiency increase of 17%
Priced nearly 8% less than its competition, the NP9150 also generates a huge 21% value lead.
If I recall it is a Enduro related bug causing 7970M to be under utilized in games like BF3, it was quite a big deal in June/July on NotebookReview's Forum, not sure if it is fixed by new drivers.
Check this thread (and the "Sager and Clevo forums") for more details:
, and AVOID 7970M for now. Its been months and no fix from either AMD or Clevo. You do not get what you pay for when bying this configuration.
Makes good sense to me.
You didn't test BF3 multiplayer wwith 64 players? The single player works fine, but the multiplayer suffers from enduro issues. Here are some screenshots taken by me:
18 fps is not fine in my opinion. Also got 8 fps at times in Civ 5. I have a P170EM Clevo with 3610Qm and 7970M. Anandtech also posted an article concerning Enduro, and they weren't aware of Enduro issues either, but when the people from Notebook review informed them about it, they were able to reproduce the issues. They also edited their article to include a mention about the issue.
The issue is real, and affect all AMD 7000M seriers card that are in laptops which have no MUX-cable. This cable allows a user to use only the dedicated GPU instead of the iGPU. When there is no MUX, the image is always forced through the iGPU, and the Enduro technology that is supposed to make this happen is broken. With Alienware's laptops that have MUX, you can force Enduro off and the issue goes away. If you enable Enduro in AW, the issue comes back.
What you get is sudden FPS drops, stuttering, low GPU utilization. It does not affect every game, but I'd still say its present in most games, e.g. witcher 1 & 2, crysis 2, BF3 multiplayer (more evident on certain maps), GTA 4, etc. etc. (the list goes on).
When you try to reduce the graphics level to get better fps, you only get lower GPU utilization and the same fps. Now this is a serious issue to people playing online shooting games and other competitive games.
Notebook review forums have numerous threads about the issue, and we have been following how the situation develops for months now. So far, AMD has been very silent regarding fixes to these Enduro related issues.
Check the comments and the last 'update' part of the article. This card has been out for almost half a year now with broken switching software.
