[techpowerup] leaked Radeon HD 7770 Specifications and benchmark

[Skurge]

N$185 better be price gouging. Cause that's reaching 560Ti territory

 

[blckgrffn]

Don't pretty much all of these cards launch too high in price and adjust down? I mean, they want to milk the higher card numbers for a bit right, since that means they are faster?

It will be interesting to see what happens to stocks of 6850/6870s when this hits as its hard to believe that there will be an incentive to keep them around.

Huzzah on the 5/6770 finally being refreshed. Get this card down to $120 already

Here are some 3dMark11 scores for comparison, benched on an older i7@3.6, which would be essentially identical to an i5-2400: http://www.neoseeker.com/Articles/Hardware/Reviews/Sapphire_HD_6850_VaporX/6.html

Shows the 6850 at about 200 above the 7770, but assuming the latter is getting excellent tess scores, the performance in older games will be way below the 6850, and the performance in tess-based games should be higher.

 

[MrTeal]

If the stock clock is 1GHz, a 300MHz OC might be a little high for many samples. Sure it's a low power part, but the stock clocks are so high that it might be tough to see much OC headroom, kind of like the 6870.

If the leaked listing is true, I'm cautiously optimistic that it will be considerably sub-200. If an MSI dual fan version is coming out at $186 on launch day, prices for a reference version a couple weeks after launch would probably be closer to $150 than $200.

 

[MrTeal]

With a 2500 , the cpu physics tests will elevate the overall scores VS a i5 750, but even in Performance settings, the graphics test is pretty much gpu bound.

Their physics scores are too high for a stock clocked 2500k. These are my results with a 6870.
Intel Core i5-2500K Processor
Processor clock 3691 MHz
________________________________________
Core clock 950 MHz
Memory clock 1050 MHz
___________________________________
3DMark Score P4507
Graphics Score 4230

Even at 4.6GHz I wasn't hitting anywhere near 11500 Physics. Either that or they aren't using stock performance settings.

And this is a 5770 clocked at 1 ghz:

http://3dmark.com/3dm11/1652339

Graphics Score 3015
Physics Score 12379
Combined Score 3018
Graphics Test1 14.69 FPS
Graphics Test2 14.86 FPS
Graphics Test3 17.93 FPS
Graphics Test4 8.77 FPS
Physics Test 39.3 FPS
Combined Test 14.04 FPS

Notice that the 5770 at the same clock is only a hair slower than 7770 in overall score but actually faster in graphics test 1.

And for reference a 5850 clocked at 1ghz (4964 graphics score): http://3dmark.com/3dm11/2012041?show_ads=true&page=/3dm11/2012041?key=g-77F6QIHqy75mfpG9ap2Q

 

[Chiropteran]

Really curious to see how they do at btc mining. Could also be a nicely performing single slot card for those who can't or won't give up 2 slots for a video card.

MSI card $186. http://hexus.net/tech/news/graphics/35161-msi-radeon-hd-7700-series-cards-make-retail-appearance/

I think it's usually the case that new-gen cards sell for a premium over their just-as-fast last-gen parts, even if the last gen card is a higher model (6850 = 7770). Power and temps are almost always an after-thought especially for the target audience for the 7700 series. I'm willing to bet we'll see something similar with the 7870 launch in March where 7870 performance = 6970 performance. The only difference here is that the 7870 is supposed to be $300 where the 6970 is $300 only after rebates right now.

 

[krumme]

This is the perfect mobile chip. And for that the retail desktop users have to pay, because otherwise the capacity goes to HP or Dell

In one year time this card will sell for sub 100usd and still make a healty profit. 128bit bus, and aprox 130mm2!, this can be made very cheap when 28nm prices goes down, and NV brings some competition.

You want cheaper and better performance and dont have to care about thermals and power,- choose 6850.

Clearly the sub 60watt part, 7750 will be priced out of this world, because it will have absolutely no competition in its niche market.

Hopefully AMD will price those cards at the highest possible.

 

[HurleyBird]

I expect that there will be a new driver that is supplied to reviewers when 6770 comes out, upping performance at least a bit.

It seems like GCN still has a lot of performance to be brought out with drivers. Wouldn't be surprised at all if this chip eventually performed closer to a 6870.

Let's not also forget that the card is more power efficient, fully featured, and may be more overclockable.

That said, I do wish AMD would price it's new cards a bit more aggressively.

It really should be a $150 part even for the full chip. Cape Verde is only 10% larger than Turks, and you can find a 1GB GDDR3 6670 for $85 even without a rebate. Power consumption should be similar, so board costs will be about the same as well. Even with the more expensive process, the total cost of a card might only be 10% or so more than a HD6670, with costs getting closer to the 6670 as the process matures.

Given the volume that these cards will see, if AMD doesn't have competition in this space for awhile they should profit handsomely if they can sell them at $150. I hope GK108 is launched in a reasonable timeframe and both of them help push these cards down to $100 where they belong.

 

[WMD]

The MSI twinfrozr GTX 560 OC is $185 with rebate. The Sapphire 6870 is $150 with rebate. I really dont see how this card can ever sell at $186. Sure it will consume less power and perform about 20% better than a 5770. But we already had the 6850 with better performance since October 2010. :\

 

[exar333]

Wonder if they will release a 7750 with essentially the same specs, but at a lower clockspeed. That might be a lot better option, if it is closer to $120 or $130 after ramping-up the clock to 1ghz+, especially if they both hit a similar ceiling.

I recall that starting with the 7k series, AMD are dropping everything below 7750 on desktops, everything lower is serviced by APU's. The performance and TDP makes sense from such standpoint, but the price definetely doesn't.

 

[Crap Daddy]

The problem with these series is not the high price for the top cards (quite understandable until one point) but the fact that all others in line will offer same performance for the same money compared to the 6000 series regardless how they will be called.

 

[Hypertag]

I really do not see how this card will ever match a 6850. 640 Streaming Processors? 16 ROPs? 128-Bit Memory Interface?

All of these are significantly worse than 6850.

 

[notty22]

It will be a big profit maker, the board design looks very simple. Minimal components, low power draw helps this. But they are sand bagging to much imo. 3 years ago, AMD launched the 4770, and it was called the 110 dollar killer gpu.

The stream processors are different to those in the HD6850.
The ROPs could be more efficient.
The memory can't be helped that much except by optimising the GPU to make less memory calls with even better Z-culling etc.

But from the outside it does looks like it will struggle against an HD6850 based on the specs, not that it actually matters.

Performance isn't the important thing. Price/performance is what matters, so hopefully the headline figure is off the mark and it's not a "sub $200" GPU (implying $150~$200), and is a "sub $150" GPU so that price/performance is good, even if absolute performance isn't the best.
If it's slower but cheaper, that's fine.
If it's slower but more expensive, that's a problem.

 

[Vesku]

This listing makes more sense to me than the 640 SP count rumor for 7770. My guess is that is the 7750 SP count. Hope this pre-order info is right, as I just can't see a 640SP GCN card being a worthy ~$150 card even at 1GHz.

[railven]

This card's other features (low power consumption, less heat, newer architecture, yada-yada) has a lot of things to prove if it is barely faster than an HD 6850.

While I don't expect this card to drop below $160 until the 68xx are completely gone, with it's performance deficiency, I'll be recommending HD 68xx to anyone looking for AMD in that price bracket unless the things I stated above really appeal to them.

While GCN is more efficient than VLIW5, I don't think it will match the 6850 with just 640 stream processor. My previous post already showed that at the same clock it is no faster than a 5770 unless heavy tessellation is involved. AMD did not bring anything new besides a new process and higher clocks.

 

[Silverforce11]

While its probably not cheaper than the 6850, it doesn't have to be. It's not meant for users with those cards to upgrade to. It's for users who want that lvl of perf/$ and much less power use when they want to buy a card now. Next gen low-end is what it is, still low-end.

 

[videoclone]

This is a low end card that will beat any intergrated video on the market... thats the whole point.. its the entry level product.. with the 7850 / 7870 being the midrange products... once Nvidia release something to compete just watch the prices come back to down to earth to replace Match the current lineup prices.

$100-$150 > 6670 > 7770
$150-$250> 6870 > 7870
$300-$400 > 6970 > 7970


At the moment because Nvidia have nothing out to compete AMD is doing what any good business would do... Making money on being the king of each price point.

maybe powercolour just has overclocked memory versions... or theyre not shipping at 1125mhz?.
At 1250mhz that should put it ~80 GB/s memory bandwidth.... still doesnt seem like enough.
