They got the wrong memory bandwidth for the R9 280 and 7950 cards... it's 384-bit.

Which is why I'm worried that the 285 won't be able to keep up. Particularly at higher resolutions.

This is a Sapphire Dual-X review, not a reference 280 launch.

The Sapphire Dual-X R9 280 comes overclocked from the factory.

This is simply a last look at the 280, relevant from the perspective that these will probably be discounted on the market for a little while.

As far as performance, we don't believe the 285 will be much faster (possibly even slower), based on specifications.

What I mean is - this is OC 280 vs Stock 760. If you get a OC model of a 760 from Asus, EVGA or Gygabyte or whatever - the margin between 280 and 760 will shrink, turning it into a battle of power an acoustics, since you can get custom 280 and custom 760 for comparably the same price.

P.S Just made a check. In most big on-line retailers in Netherlands, Germany and Belgium, the SAPPHIRE DUAL-X R9 280 3GB GDDR5 OC w. Boost cards are actually more expensive than OCed 760s.

SAPPHIRE DUAL-X R9 280 3GB GDDR5 OC - 270 EUR

ASUS R9280-DC2T-3GD5 - 245 EUR and it is clocked 40 Mhz higher

GIGABYTE GV-N760OC-2GD - 230 EUR and it is clocked 100 Mhz and 120 Mhz more with Boost compared to reference model. That is more than 10% over-clock and it is enough to surpass the OCed 280.

I agree that the 760 reference was a little misleading along with not including the power and temperature measures from the 760 as well.

You can't buy a reference card on Newegg anymore. All the Radeon R9 280's come with custom coolers.

There are still a lot of 760's with reference coolers available, however.

Nevertheless, you guys are probably picking nits and missing the point. The margin of win/lose is so close that it's irrelevant, as I point out in the conclusion page. A random sample of different benchmarked games might show 760 strengths better than the newest titles that we chose for relevancy.

The point is, they're so close it's almost irrelevant which you choose. Pick based on price and your preferred features, or your prevelance for Radeons or GeForces.

As far as power/noise measurements, we'll be digging into that much deeper in an upcoming Radeon review. ;)

I'm curious. Why? There seems to be no advantage to the R9-285 at all except lower draw power. That's it. Who cares about a higher clock on the memory when its gimped by a 256 bit memory bus. Do the numbers.

You can see 176 GB/s memory bandwidth vs 240 from the Tahiti. Both have the same exact number of shader cores and Tahiti also has a slightly higher base clock. Seems to me that Tonga at the same price point has no benefit whatsoever. Don't understand this card.

I understand and acknowledge that. The point I was making is that you ( perhaps inadvertently ) put this 7950 Boost rebrand in the best possible light by using an aftermarket cooled and OC'd version against the stock clocked and cooled competition. But since there are no reference models of the card available , that may have been AMD's aim - to put this rebrand in the best case scenario. But you the reviewers should try and level the playing field.

Honestly it's not a big deal. I understand where you're coming from , it's just my opinion is all :D

I hear you, man.

Like I said, we've got a thorough comparison coming in the near future with more details. This was more of a goodbye to the 280, really, which i believe will be a better option than the 285 unless you *REALLY* want to save power.

That's what I am talking about. To me efficiency is nearly as important as performance assuming a near equal price and close performance. Even 10% less performance at 60 FPS is only 54 FPS something I can't really notice without fraps on.

I would like to see how the new cards are stacking up to the GTX 7 series though. Since the GTX 760's have seemed to have not fallen in price I might think about selling mine off to get something new.

Splendid
you guys can wait and I will enjoy my fully under warranty msi twin frzrs i picked up off of ebay for $125 a piece.

btw i already sent one into MSI and within 10 days it came back fully repaired. my daughter (autistic) opened up my rig and dumped juice on the GPU and MSI still replaced it without conflict or headache (I did clean with 99% alcohol). they have just earned my money for future purchases

The 280 vs 760 price debate is very location sensitive. In Europe, where hardware is much more expensive than US, the GTX 760 is priced a lot more competitively than the 280. Also, I have never seen reference designs for sale with few exceptions and those being high-end cards with pre-order mainly. My comments about the use of a reference design for the 760 is not that I want to boost up nVidia. To be honest I am from the ATI team (it will always be ATI). But my software requirements and specifically prices places nVidia in a rather good position.

Toms, please stop using the photo gallery plugin you currently use. My iPhone cannot handle it. It causes my phone to stress and slow to a crawl and then doesn't even load the photos. Makes these articles unreadable on iphones.

I share your sentiment on the matter. AMD is attempting to lower the power draw of their cards, not through architectural engineering advancements, but by reducing capacities. I'm baffled at this strategy - I see it more like a stratagem.

Offer less performance for the same price but call it a win on efficiency grounds. I'm very curious to see the power draw on this card at stock and OC'd.

Don't expect the 256bit bus to gimp the card. This depends greatly on the gpu's design. Just as the pcie bandwidth can be offset by dedicated video card memory so can memory bandwidth. If the tonga for example has more cache or uses a more efficient memory design. While the 285 will be a fairly powerful card some leaked specs on the Nvidia 880 suggest it will have 4GB's on a 256 bit bus.
