The Test

Since the reference GTX 650 Ti Boost is completely identical in build to the reference GTX 660, let’s jump right into our tests.

NVIDIA’s launch drivers for the GTX 650 Ti Boost are the recently released 314.21 driver set, which as an aside we’ve discovered fix Titan’s OpenCL issues and we’ll be following up on that next month. Meanwhile for the rest of our cards we’ll be reusing our data from last week’s 7790 launch, so 314.21 for the other NVIDIA cards, AMD driver 12.101.2 for the 7790, and Catalyst 13.2 B7 for the rest of the AMD cards.

Please note that the GTX 650 Ti Boost NVIDIA is sampling is the 2GB card. We’ll take a look at 1GB cards later once those arrive, since they were a late addition.

On a side note, by the time you’re reading this, this will be the third major GPU article we’ve posted in as many business days, and we still have one more to go tomorrow. So we apologize in advance for not having had the time to run any additional NVIDIA cards besides the 600 series; we’ll get that caught up in Bench once this batch of launches and conferences is over.

    Any specific reason as to why the 1gb wasn't used? Reply

    In addition, the 7790 will have 2gb cards as well so I'm just confused overall. Reply

    Probably because nVidia only sent a 2GB sample. I assume once retail cards are available a 1GB model will be tested too. Reply

    Of course they didn't send the 1GB model. It's absolutely completely positively ridiculous. It has no business existing. Reply

    They say why in the article. I think I'd read it before commenting.

    lol

    I guess I don't see where that's in the article. Can you comment on the paragraph? Reply

    "Please note that the GTX 650 Ti Boost NVIDIA is sampling is the 2GB card. We’ll take a look at 1GB cards later once those arrive, since they were a late addition."

    Second page, very middle.

    From page 2 (clear as day, if you just bothered to read)

    Thanks for clearing that up. I will have to wait to see if the 2gb is a paper launch. Reply

    2GB 650 TiB launches this week. It will be 1G that will come later. Reply
