Didn't they try something like that with the original Phenom? or was that simply ACC i'm thinking of.....

Surprised nobody has mentioned the lack of h.264 decompression yet.

That's a pretty big thing to be missing in a card like this, and I think it speaks volumes about what to expect in terms of driver support (the first couple months will be adding features that should have been there in the first place instead of working on performance improvements.)

This is one of those things that has been a big strike against the 7xxx series in my mind. Drivers in general have been an issue for AMD in the past, and that seems to be spilling into the present. It seems like the drivers just plain are not ready for prime time.

Do they have a 7xxx Vista driver yet? Lack of a Vista driver for the flagship card isn't a big deal. But when you consider cards without a 6-pin connector, you are talking about a teenager popping a light gaming card into mom and dad's Dell. It's a different world of expectation in terms of willingness (or ability) to upgrade an OS.

One more thing to consider...
With performance like we've seen with Civ:5 and Batman, wouldn't you expect that developers will start using compute features significantly more now? I mean nVidia and AMD both have hardware that can handle these tasks now.

Tesselation seems like a feature that's relatively easy to add to a console port to improve visual detail over a console version and make a game "PC worthy". That'd be my main reservation in purchasing a 6850 level card now. In the past, the threat of significant compute requirement to high quality features in games was tempered by the existence of the AMD cards that weren't so great at tesselation and compute, but now with both brands capable, I wouldn't be surprised to see the floodgates open.

The 68xx are ALL eol cards. Their prices reflect that. When they were new they had more performance but also higher prices than even the 7770. Your comparing eol prices to brand new prices. Even without performance or whatever involved, brand new stuff is always more expensive than the same item will be a year from now. A year from now the 7770 will be cheaper just like the 68xx cards got cheaper. Same thing that happened when the 5770 was released and the 4870 offering more performance for similar or better prices. Nothing new here...

The 6850 launched at $180, and the 7770 launched at $160. So yes, the 6850 was 12.5% more expensive than the 7770 at launch, but was also 5% faster. In the 16 months since Barts launched, including moving to a new full node and a new arch, there hasn't been more than a 10% increase in perf/$ comparing launch price to launch price. At least when the 6870 launched it was faster than the 5850 and its launch MSRP was also $20 less than the launch MSRP of the 5850. That was even on the same node. The 7770 is a bad value comparing launch to launch, not even taking into account that you can buy an HD6870 today for $155 ($145AR) that thoroughly outperforms the 7770.

7700 series cards up on Newegg, seems like they realize the SP count is a bit blah on the marketing side as the SP count is missing on the details tab (all the other radeons list SP counts afaik). Bottom line though is that AMD shaved some size off the ~$150 parts die size, focusing on profit over offering significant performance improvement over the 6850 which had a launch MSRP just $20 more than this 7770 MSRP.

Edit: Boo, hiss at AMD on the 7770 choices. 7750 seems a well thought out HTPC card. 7770 looks like an OEM card being dangled in the retail waters to try to catch some sucker fish, ahem, I mean customers.

At least the cards are available for MSRP. I don't think an increase over it would have moved much stock.

One other interesting point.... 5770 bandwidth was higher than 7770 bandwidth.

Shouldn't this at least have used memory at 4.8 GHz to match the 5770?

I suppose it will make for easy overclocks, but it seems like stock bandwidth should at least equal 5770 bandwidth.

If they produce some half-height cards these would pair nicely with some of the smaller minITX cases.

Well, I guess I have to amend this. The HD6870 that was at $145AR on NE's site just went out of stock. The new lowest price one is $150 with free shipping. No 7770s OOS yet.

Techreport tested Skyrim with high-res textures and it looks to me the 6850 and thus 6870 handles it better than the 7770. Very playable 1080p performance out of the 6850 in their Skyrim test.

But as for future games, these GCN cards are more capable in terms of tessellation than the 6800 series.
Thinks for the suggestion. I just checked it out and see what you mean. I'll need to check other sites to see if they get different results, but if it holds true then the 6870 is still on the table with the 7850, but the 7770 is definitely out of consideration.

2 years after the 5770 we should be getting the 7770's performance for $100 - $125, and these cards should be labeled 7650 and 7670.

AMD basically rolled all their low end in these two cards. 76X0 wouldn't make sense, because there wouldn't be no 77X0.

If you would change every post mentioning the 7770 to 5770 and every 6850 to 4870, I would swear I'd gone back in time. The price will go down, performance will go up with time, just like with the 5770. Skip 2-3 years ahead, and everyone will be dissapointed, that the 10770(770?) failed to meet the great pref/$ of the 7770

But for now, the 7770 is priced horribly, and the 7750 is priced slighly too high. Pass on both for some 6 months or so.

No, the 7750 is priced almost perfectly. It's the same speed as the HD 6770 and the same price, plus it consumes less power, is smaller, and doesn't require an auxiliary PCIe power connector. AMD's partners will probably find it very easy to make versions that are fanless and half-height, too, making it a perfect card for a gaming HTPC.

But the 7770 doesn't make sense at its current price.

The 5770 had more bandwidth than it could use though. So it would be interesting to see if the 7770 is bandwidth limited or not.

I called both AMD and NV headquarters this morning and asked them to send me the 7970 and 580 respectively for free. Surprisingly, both companies refused. I am now furious and will refuse to buy from either company now or in the future.

I blame them for my budget/finances not allowing for me to spend anything on a GPU, but still feel entitled to the latest and greatest graphics performance.

In short, capitalism sucks.

I bought 4 7970s today because I earn lots of money and demand only the best performance. I don't care if each generation of graphics cards becomes more expensive, obviously those that bought previous enthusiast level products from the last generation have not increased their income necessary to keep up with the new enthusiast line. Peasants. How can you call yourself a PC gamer enthusiast if you don't buy the latest graphics cards with the largest model number irrespective of actual performance?

If you can't justify the price it must be because you are poor or lazy. Or both. There cannot possibly be any other reason.

I know this is post was being sarcastic but you have pretty much nailed it.

Do you whine when you go to a car dealership and the Mercedez-Benz is $70,000? Do you go to the jewelry store and cry about the Rolex watch being $7,000? Do you go to a designer clothes outlet and cry about a suit that costs over $1,000?

Premium products have premium pricing, suck it up.

Price will go down somewhat but not sure about performance. 5770 has not really surpassed 4870 1GB as many people said it would except games had become alot more demanding of VRAM making it the 4870 512MB perform horrendously in TPUs benchmarks. The 6850 and 6870 has not really surpassed the 5850 and 5870 as people predicted either except in tessellation bound benchmarks where they already performed better from day one.

Remember how many people were upset with the 6870? It was Slower than the 5870 that many people expected it to replace. The 7770 is Faster than the 5770/6770 its replacing and close to the original 5770 pricing. The 7770 is considered a sub-par value because the 68xx series exist which and are at EOL prices. If only the 5770/6770 currently existed, which the 7770 is meant to replace, how upset would people be? Of course, while 68xx cards exist at their current prices they are the better buy for absolute performance and I have seen no one say differently. But remember they are eol and will be gone long before the 77xx are eol. No different than the 5770/4870 days.

6850 launch msrp was $20 more than 7770, not a good next gen value imo. Hope Nvidia does better replacing the 550ti.

If or when it his $130 or less than the 7770 will be a worthy next gen card of it's type. At the $160 price we are missing out on 100ish SPs, no way am I going to buy it or recommend it while the 6800 series is being cleared out.

These cards are selling pretty well, I don&#8217;t think 10/20 (£/$) is going to make or break a deal (especially in this price point) if people want new features with lower power on 28nm (HTPC etc.), they will buy it anyway and that is exactly what&#8217;s happening.

A new generation Mercedes model will not suddenly jump up 50%, that absolutely does not happen. You will not see a new generation E320 suddenly be 50% more expensive than it's previous version. Your analogy is beyond ridiculous not to mention completely wrong and only serves to make a point against your own argument.
