[The Tech Report] Does the Radeon HD 7950 stumble in Windows 8? - Page 10

post #91 of 452
I wonder why they act like there isn't a tool just to control frame latencies, like RadeonPro. Calculate average fps, reciprocate to find frame latency goal, set and watch the silk smooth game progress.
The skipped frames always miss 5 ms just like Wenckebach av nodal heart block smile.gif Missing 3:2.

I dont care imo. I am not butthurt fanboy. My 7970s are such a good card and they works fine. But if it is a problem amd should know and fix it or whatever. But from my personal experience my cards is smooth. Dunno if someone more sensitive than me can tell a difference thought

To all the Nvidia fans and people that think the HD 7950 is a crappy GPU:

I hope that this review is not right, otherwise outside of bitmining or OpenCL stuff there's no reason to buy midrange AMD GPUs. Maybe GCN & OpenCl will be better supported in the future, but to the layman nobody cares if it is AMD or Nvidia unless they're using CUDA acceleration and PhysX. I don't think anyone can argue that Nvidia's Kepler cards are better in terms of actual hardware. They are crippled memory bus wise, less VRAM, use more power, and they are stock clocked higher (less OCing too).

Nvidia already has CUDA, PhysX, "way it is meant to be played" titles... so this would be a GPU death of AMD unless they can get their drivers to work better.

Side note: The problem with Nvidia having higher fluidity is that AMD stock will just drop lower... which means AMD will be failing at everything.

Right now up to the $300 mark, Nvidia doesn't have a stranglehold. If they can break through to the GTX 660 Ti and GTX 660 (~HD7870 which is plagued by black screens), then AMD is in deep trouble because the only cards less than that are the GTX 650 Ti , GTX 650, and GT640 (and other crappy stuff like GT 630, GT 620, Gt 610).

about performance, TR in past reviews has published graphs with good frametime for AMD last series ... only dual gpu setup was abnormal ... now with single card rolleyes.gif
AMD was caught cheating to get good reviews ...there is no excuse for this way of acting
How were they caught "cheating?"

Also, those graphs aren't proof of anything. The results are within margin of error.

+10% performance -20% efficiency than the original model ... all reviews equipped with decent tools has proved
And yes, leakage goes up as clock speeds increase. This is obvious.

This review suggests otherwise.

Interesting article, maybe their 7950 is defective as mine is near 16ms (20-25ms as "spikes") in BF3 and staying on an average of 14-20ms with my other games (mostly DX9 / 10 titles) according to MSI Afterburner... I hope they did a clean install of the drivers before testing.

My friend have a 660Ti and the two cards seemed equally smooth to our eyes.

Will try to monitor this tough, could be an issue with the drivers.
Is there a way to make log with Afterburner?

In afterburner, go to the monitoring tab and check Log history to file.

I have and HD 7870, and I haven't had a single black screen yet. I'm pretty sure the Cat 12.11 drivers fix that issue.

Seriously, there were people claiming that Nvidia "bought" the review...

I know, wth.

I'm willing to bet Nvidia had no prior knowledge, and TR was just going about their business doing another video card review. ( I know that sounds far fetched and all wink.gif )

Agreed, this way we can rule out that they have a bad card.

Windows 8 vs Windows 7 has been ruled out.

They also need to address and investigate if it's bad drivers.

No matter what, what ever else they do, there will be those who just will not believe or accept their results, or this type of methodology.

I apologize this is not a repost as I was led to believe, reopened.
It might as well be. I am sure it will turn out the same.
