The fact that we're doing this right now, bringing another NVIDIA review to you before the GPU is released, is not a shock to us. You know where most of our information comes from for NVIDIA video cards these days? The same place most of our readers get it from; the internet! Of course we get some information from partners, but even they're quite often kept in the dark.
The one thing I could've told you, though, was the second we got our hands on a GTX 660 Ti, we were going to start testing the card straight away. Even if NVIDIA wanted to work with us on this video card launch, we would've said no. Not because we're trying to be difficult, but because NVIDIA simply don't have enough respect towards us to support us on the high-end models and choose to only come out and play with us on the mid-range and lower ones. This is obvious by the fact we still haven't tested a GTX 690.
We're actually expecting retail versions of the GTX 660 Ti to start coming in, but out of respect to the partners that we like, we will follow the imaginary launch date that doesn't really exist to us. That doesn't stop us from having a play with a video card that came to us literally tonight. That is a video card that arrived with no package, no bundle - just the card and a driver CD. Just like the GTX 670, though, we reviewed this video card from a company's R&D department and while the cooler design is new to us, when the model officially launches, it would be obvious who sent the sample. For that reason we have to refrain from pictures of the video card again. To be honest, though, we feel that people care more about the results than they do the look.
The card we're looking at today carries with it the default clock speeds we'll see on reference clocked GTX 660 Ti based cards and that's what we'll be testing at today. The bottom line is we don't want to bite the hand that feeds us, and for that reason, we don't want to do anything that can give away who sent the card to us. While we're happy for NVIDIA to winge at us, we don't want them winging at the people who give us the ability to do this.
There's not a whole lot we can do today when it comes to showing the card. We will, though, check out the (edited) GPU-Z screenshot and quickly cover the clock speed side of things before we take a closer look at the testbed we're using and the cards we'll be using in our graphs today. Once we've done that it's just straight into the performance side of things.
Quickly, though, before we get into the specifications. It's important to know that here at TweakTown we have no problems respecting NDAs. We've signed more than we can count over the years and followed every one of them as best as possible. Like most websites, we've made the odd mistake when it comes to translating the time to our locale, but content has always been removed when that's happened. What we're doing here today isn't breaking an NDA for the simple reason we don't have one. If you're a website and you have a problem with that, take it up with NVIDIA - don't complain to us about it. What we're doing is essentially breaking "street date". Fortunately 99% of our readership loves that and that's good enough for us. So let's get into the specifications of the GTX 660 Ti.
Looking below we can see the main specifications. Looking at the core you can see we've got a 915MHz clock that is boosted to 980MHz. Looking below you can see we're dealing with 1344 CUDA cores and while not shown, we're on a 28nm GPU.
On the memory side of things we're dealing with 2GB of GDDR5 that comes clocked in at 6008MHz DDR. Looking above you can see that we're sitting on a 192-bit memory bus offering a total of 144.2 GB/s bandwidth.
