Note that a GTX460 1gb now comes in two flavours. There's the actual GTX460 1gb with 256bit and 32 ROPs vs the GTX460 (768mb) with 192bit and 24 ROPs.

The 192bit GTX460 isn't as fast as the 256bit GTX460, but they're priced pretty close ($140 vs $150). Be careful when shopping for the GTX460 and purchase the 256bit (used in the review) not the 192bit.


The 7xxx series seems to be close or lead the pack on DX11 with the exception being AvP (but I'd say BF3 results weigh in better because that's what people are actually playing). As the price drops (hopefully due to NVIDIA competition) and we keep shifting toward DX11, I think the 7770 will get better with age.

At least in Sweden the GTX460 is the same price as HD7770, while HD6850 is a little cheaper.
From a price/performance perspective that makes GTX460 only the best option for PhysX and GeForce3D.
- The 6850 is cheaper and use less power.
- The 7770 is same price, but use substantially less power.

It is not "now," it's been like this since these video cards were released. That is why in the graphs, tables, and text we made sure to write "1 GB" after the name of this video card.

I thought the GTX460 was released as two versions with a 1gb 256bit 32 ROP version (GTX460 1gb) and a 768mb 192bit 24 ROP version (GTX460 768mb). Later there was the GTX460 SE (which had less CUDA cores I believe). However, more recently, I've seen GTX460 768mb relabeled as "GTX460 1gb", while retaining the same specs as the original 768mb- the only difference is that they now have 1gb of VRAM instead of 768mb.

While most people who read up on the original 1gb and 768mb would know the difference, the marketing strategy of adding more VRAM and then marketing it as a "1gb" model is pretty tricky. In fact, the only way to differentiate the two on Newegg is by the memory bus. Therefore, I feel that differentiating the two GPUs based on VRAM can now cause confusion.

Notice how easily it could be for someone to confuse the two? (The warning wasn't directed at the article, but to other readers who might not see the difference)

I agree 100% with you, and I hate NVIDIA and AMD when they launch video cards with different specs using the same name. The user reads a review of the beefed-up model, and then buy the cheapest one, which has different performance level. It would be easier if the manufacturer called it something else, right? For instance, calling the 768 MB model as GTX 460 and the 1 GB model as GTX 462 or something like this...
