Xotic PC NP9150: Striking Back At Kepler With Radeon HD 7970M

By Thomas Soderstrom
published

We've seen the efficiency of Nvidia's Kepler architecture first-hand on the desktop. But AMD's Radeon HD 7970M pulls off a stellar showing in Xotic PC's Sager NP9150 notebook, reminding everyone that even a Pitcairn-based flagship packs a serious punch.

Benchmark Results: Audio And Video Encoding

The bottlenecks that we mentioned on the previous page should only affect 3D applications that push very low GPU loads. Productivity and content creation applications aren't affected.

The trend in audio and video encoding performance appears to favor Xotic PC’s NP9150 configuration, despite their similar CPUs. We can think of one possible reason for this: Eurocom built its notebook using three 4 GB modules, while Xotic PC used four. It makes most sense to install memory in pairs, since the mainstream-oriented Ivy Bridge architecture has a dual-channel controller.

  • Did the test show any sign of 7970M utilization issue? It is a well known problem reported by many members from Notebookreview forum.

    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.

    BF3 results look fine to me :)

    I find it hard to believe that the 7970M performs a bit too well in Battlefield 3. Even the 7870 and 660ti gets lower fps with the same settings at 1080p.

  • No games on 7970m doesant play fine. Most of them are affected by enduro underutilizaiotn which basicly causes the card to notutilize fully when lowering settings in games. For example , in bf 3 multiplayer( as there is no problem in singleplayer) when you enter a lrger map with 64p on it, youl get around 35 fps maxed but with dips down to 25 fps which is not enought for a fast paced shotter. So when setting are lowered you expect to get better fps right?? thats not the case with 7970m- the fps remains the same but utilization of the card drops down. This also happens in many other games that are sometimes even unplayable. You just cant achieve stable 60 fps no matter what settings- the lower the settings go, the lower the card utilization is. There is a logging thread, and many other threads regarding this issue on notebookreview. Amd adressed that there is a driver coming soon, but for users that have this card form half a year now its taking pretty long..

  • I concur what Mahalsk said. A 7970M in a EM-series Clevo laptop IS NOT A GOOD DEAL for the price they are asking, since the card doesn't work properly. This is the case with all EM-series laptops and all 7970Ms out there. Even the 6900M series of AMD cards are beating 7970M at the moment with the Enduro issue unsolved.

    Check this thread (and the "Sager and Clevo forums") for more details:

    http://forum.notebookreview.com/sager-clevo/682097-7970m-logging-thread-games-utilization-issues-only-post-logs-no-questions-please.html

    , 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.

    Crash I like the new metrics.

    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.
