AMD's New Radeon HD 7950 Tested 120

MojoKid writes "When AMD announced the high-end Radeon HD 7970, a lower cost Radeon HD 7950 based on the same GPU was planned to arrive a few weeks later. The GPU, which is based on AMD's new architecture dubbed Graphics Core Next, is manufactured using TSMC's 28nm process and features a whopping 4.31 billion transistors. In its full configuration, found on the Radeon HD 7970, the Tahiti GPU sports 2,048 stream processors with 128 texture units and 32 ROPs. On the Radeon HD 7950, however, a few segments of the GPU have been disabled, resulting in a total of 1,792 active stream processors, with 112 texture units and 32 ROPs. The Radeon HD 7950 is also clocked somewhat lower at 800MHz, although AMD has claimed the cards are highly overclockable. Performance-wise, though the card isn't AMD's fastest, pricing is more palatable and the new card actually beats NVIDIA's high-end GeForce GTX 580 by just a hair."

    But does it run Linux?

    No, seriously... last time I tried to install Ubuntu with an ATI card (a few months ago), I couldn't get dual monitors to work correctly.

    The restricted drivers exist, but are unstable, awkward and painful. Linux and Nvidia - a bit better in my experience..

    When Kepler comes out expect all these cards to significantly drop in price.

    GCN was a huge cost on AMDs part, and Kepler will be a refinement of Fermi, so Nvidia will aggressively price the 600 series (especially since they won't launch for another 2 months) and make profit on them. And expect AMD to take a loss on the investment but not on the returns from fabrication on the 7900 series (assuming they fab the 7800 and lower cards on their old VLIW architecture like the roadmap from last years aid they would).

    So when Kepler comes out, it will probably be aggressively priced, and AMD will drop prices to match. For now they are exclusively the only maker of "next gen" gpus after 2010s 500 and 6000 series, and Kepler is 2 months away, so AMD is milking it.

    That's why the driver is called 'nvidia' not 'nv'. 'nv' is the incomplete, OSS driver. 'nvidia' is the driver supported by nVidia. At its core, it's the same driver as on Windows.

    There are console first person shooters, and then there are PC first person shooters.

    Try running BF3 on high/ultra in high resolution. My reasonably overclocked GTX 560Ti can just barely handle high in 1080p, ultra utterly murders it with clear jerkiness present in many situations. On the other hand, it eats MW3 for breakfast in pretty much any resolution/quality I could throw at it. You don't need to crank out a "20 km horizon" to overload a modern card.

    And frankly, if a game makes your card render 20km of ground in level of detail that actually affects it, of which you will literally see only a few hundred meters, it's doing it wrong. Badly wrong.

Money is better than poverty, if only for financial reasons.
