Official HD7770/7750 Reviews Thread

[LOL_Wut_Axel]

As for the HD 7770, we get basically the same situation as with the 5770, which costed more for what was at the beginning slightly lower performance than the 4870. The HD 7770 is priced higher so the remaining 6850 inventory sells out and after it does they'll lower the price to $150 and $140. At its current price, though, it makes no sense.

Product check, placement check, promotion check, price....no-check

3/4 from amd's marketing team, better luck next time.

The whole review was flawed, IMO.

The 5770 was the step down from the 5850 for much of it's early life. Later, the release of the 5830 added a step in-between, but even then the 5770 still had a fairly high performance role to fill.

The 7770 doesn't fit into the same category. There will be an entire 7800 series in-between the flagship 7900 cards and the 7770. The 7770 is now the low end, not the step below the flagship enthusiast cards. It's not the equivalent to the 5770 in any way other than price, IMO. And price will change to meet the demands of the market.

The 7850 or 7870 will be the real replacements for the 5770. They will be the cards that people buy who can't afford the best of the best but want something one or two steps down from the high priced highest tier.

That said, I'm still curious about the 7700 series for a couple reasons. I'm wondering how bitcoin mining performance is, especially mhash per watt, and I am wondering if any manufacturer will make a single slot 7770. If the price drops some and a single slot version is available, it may be a nice choice to make a very dense bitcoin mining box. Not as good as a 7970, but much cheaper and possibly just as efficient.

Given how nicely mining scales with shaders and clock speeds and how the 7970 performs, I would guess that a 7770 at 1GHz would be somewhere in the vicinity of 185MHash/s. It would be interesting to see though, I didn't see a review that tested it.

The only problem is NV has never been an economical company: because of AMD we are going to pay through the nose. Mark my words.

Because of AMD? AMD does not control Nvidia's MSRP. If you're going to bitch about the price of Nvidia's video cards, then lay the blame squarely at the feet of the company actually responsible.

NVIDIA.

 

[Infraction Jack]

I will probably get the 7750.

 

[MrTeal]

Why? It delivers on average the same performance as the HD 6770, consumes a lot less power, is smaller, and costs the same. There's no card from NVIDIA that directly competes with it, either, since the 6770 didn't directly compete with the 550 Ti, which is priced higher and is slightly faster.

They don't cost the same though, at least not yet. You can buy a HD6770 with a game for $100 before a rebate and $80AR, and that's just looking on NE without trying to find a deal. The only HD7750 listed on Amazon so far is $157, but even when they drift down to within $10 of their MSRP in the next few weeks, they'll still be 50% more expensive than an $80AR HD6770.

The HD7750 is going to be an excellent value card once it drops to where it should be, but until it's around the $100 mark after rebates or all the old Juniper cards dry up in the channel, it's going to be at be at best a tradeoff of price for efficiency.

Yep. I agree with you.

This isn't exactly a new development though. From time to time you can still get a 4870 for ~$50 or a GTS 250 for $30. Why lay out a Benjamin for an ~equivalent card when you can spend half as much and get roughly equivalent performance if your PSU is up to the task?

Granted, Cypress has DX11, but you could argue that it isn't really fast enough to take advantage of it. Still, it's a selling point and all the stickers on these new GPUs are just more of the same for 2012.

That hasn't stopped people from buying the shiny stuff instead, I think some folks decide they are going to spend ~$150 or whatever first and buy something that costs about that much.

Because of AMD? AMD does not control Nvidia's MSRP. If you're going to bitch about the price of Nvidia's video cards, then lay the blame squarely at the feet of the company actually responsible.

NVIDIA.

Haha, common sense fail. Come on Creig, since when do companies set their own prices for the things they make? I've got some kool-aid over here for you that will set you nice and straight... /endextremesarcasm

My Liberal Arts education is not failing me here. Some folks need to take an economics class. Supply and demand... A producer picks a spot for them to intersect in order to maximize their profits based on projections and adjust prices to meet reality. If they cannot make a profit they exit the market. Competition is essential to keep monopolistic behavior to a minimum...

Any sane enthusiast should be worried that AMD is going to exit the high end desktop CPU market, not that AMD and Nvidia will be selling $2k GPUs next year. We are lucky that the market is as competitive as it is on the GPU side.

Don't like the current prices? Don't buy them. I am pretty sure this is how modern economic theory works at an individual level.

You may find out that others are willing to pay the premium. I would pay ~$700 for a MacBook pro in a heartbeat. Too many other people are willing to pay more

 

[Crap Daddy]

Can someone find one reason why anybody should buy the 7770 over the 6870, 6850, GTX460 1GB, GTX560?

 

[LoneNinja]

I'm really liking the 7750, it's low power draw will make it an excellent card for upgrading OEM systems, and is great for anyone looking at a low power solution. Once again a little over priced, but not by much.

Like the 7770 too, it's a good replacement to the 6770, I just hate the price. Different reviews seem to be getting different power readings on these things, but given the low power draw and product placement I woudln't expect it to out perform the 6800 cards, AMD just foolishly priced them higher.

It seems to me everyone complains about ATI/AMD pricing with every new generation. 7000 series is overpriced...well so was the 6000 series and 5000 series based on countless forum threads I've read in the past few years. Everyone seems to remember the 4000 series and how it smacked Nvidia around while aggressivly dropping price, sounds like it was done to gain market share and regain customer faith after the 2000/3000 series cards failed. Once the 6000 cards start to dry up from market and Nvidia gets some 28nm parts out, and there is a surplus in the market, we will see price drops and rebates on the entire 7000 series.

No.

The 7750 however looks nice - not requiring external power is a huge deal. But the 7770 is just lackluster unless the price goes down substantially.

My current PSU will handle a 7770 no problem, might not handle a 6850, and much more likely won't handle the 6870. There is your reason!

But seriously I still wouldn't bother to buy one at this price. lol

I agree with this. For low-end OEM systems, this will be a great card to throw in and do some OK gaming. The 7770 is over-priced and garbage at it's current price point though.

Solid Power consumption all-around, but nothing 'earth-shattering'.

 

[Infraction Jack]

I have limited amount of power in my ITX case and the 7750 would work nicely in it.

 

[Rvenger]

7770 = 6790 w/ DX 11.1 and lower power consumption. Might do well to crossfire them if you can snag a good deal.

 

[Stuka87]

The power consumption is awesome. No arguing that. I was expecting more performance. With the 7770 being closer to the 6850. Just priced a bit higher than it should be, but it will drop. Just like the 5770 did not long after its launch.

For those comparing prices of the 7770 to the 6850, you need to compare launch prices, not current prices. The 6850 is far cheaper now than it was when it launched.

But now would be a great time to get a 68x0 before they sell out as I am sure production will stop soon, if it hasn't already.

 

[gladiatorua]

With all this AMD "bashing" it looks like people don't understand that with Nv's Kepler launch months away AMD has enough time to roll out 7xxx series properly. Without cannibalizing sales of last generation cards left on the market. Without repeating last year Llano debacle when demand was much higher then supply. Without typical half-assed release practices we are all already used to.
I'm sure AMD knows more about Kepler than those who spread rumors and acts accordingly.
If you want new generation card RIGHT NOW you have to pay premium. If you don't want to pay premium you have to wait. It's that simple. The prices will fall. And very soon.
But there's always a chance that AMD f*cked up and tries to screw everyone even if in the end it will result in losses. A lot American corporations tend to display such irrational behavior.
But I'm an optimist. And I like AMD and their architectural ideas. Too bad they only work for their GPUs.

 

[blackened23]

Gladiatorua, I think the complaints are centered on the 7770. I like the 7970 too and own a couple of them, but when speaking of the 7770: The performance doesn't match the price, and power savings alone doesn't justify the cost. I like AMD as well, and I root for them because I like rooting for the underdog (in both sports and electronics) However, the 7770 simply doesn't live up to expectations IMHO.

 

[Imouto]

I can't prove this, but I believe the Juniper was artificially priced high (especially at first) for the retail market so OEMs would get the bulk of them. Could be the same stunt here.

Agree with this. Advertising a cheap prebuild/OEM PC with a 7770 that looks pretty expensive would be a great bait.

 

[LOL_Wut_Axel]

Haha, I agree with you. Craziness.

There are plenty of folks who want to play Star Wars on their shiny new Dell/HP/Acer/whatever and the 7750 just became the defacto card for that application IMHO.

The 7770 will come down, it has to. It's tiny die size and small memory buffer means that when the time is right (ie, nvidia is bringing competition) we'll see these cards at ~$75/~$100 like the current 6750/70.

I am excited about the compute power, as others have mentioned. Two 7770s folding away should do well without crushing your power bill, I am hoping for ~10k+ ppd each for F@H, ~7k ppd for the 7750 which is what the 5770 manages with the new OpenCL WU's. As they optimize work for GCN that can only get better

They do have FP too, even if it is slow it is there.

To be clear - I am not really "excited" by this launch, but glad to see things moving forward.

Also, will we hear complaining about IVB not moving the ball forward in regards to performance? There is a strong chance that IVB will be about perf/watt and not absolute performance and adding some features that are not immediately useful.

I wouldn't get too crazy about these cards for folding@home if I were you. Even a GTS 450 will probably be MUCH better for that. Remember that one of the reasons why NVIDIA GPUs do so good at it is that the program is better optimized for CUDA.

The price of the HD 7770 will definitely go down, but only after the remaining stock of HD 6850s is sold, so that's still around two-three months out. By then the price will be lowered to $140-150, and before a year from now we should find the 7770 at $120-130 and the 7750 at $90-100. That's unless NVIDIA comes out very competitive, and if that happens three months from now we could find the 7770 at $120-130. At that price it's very attractive, but as it is now the 7750 is a very good card at $110 considering it has the same performance as the 6770.

 

[quest55720]

Good cards at a bad price especially the 7770. The 7750 will be a really great card once under 100 dollars. Be perfect for upgrading OEM systems for family and friends. Also I would like to see a passively cooled 7750 be a great HTPC card.

 

[blckgrffn]

Even a GTS 450 will probably be MUCH better for that. Remember that one of the reasons why NVIDIA GPUs do so good at it is that the program is better optimized for CUDA.

I don't think this is necessarily true any longer. They have been putting development into OpenCL Work Units. Based on what I have been able to learn on good ol' internet, a GTS 450 that is not clocked to high heaven and sucking the juice is going to turn in ~10k (at best) ppd and eat ~110W (conservative?).

AMD has a legitimate shot at beating that.

I've observed this myself, my 6570 runs ~3300 ppd with OpenCL units where it was doing about 1800 with the old ATI based WU's. A 5770 runs 7k ppd with the new WU's, if I remember correctly.

Obviously, it makes more sense for the F@H folks to focus on OpenCL versus Cuda unless there is a huge performance disparity for some reason.

Err, no.

The HD 7770 is 10% faster than the HD 6790 as it is now. Now, these are new cards on a new architecture, so take into account their performance will improve by a good amount in the next one-two months depending on how aggressive AMD is with their new driver releases. When that happens the 7770 will be only be ~2-3% slower than the 6850 and around 15% faster than the 6790; now that I look at it the HD 6850 is definitely slightly faster today. With new drivers the HD 7750 will be going from a tiny bit slower than the 6770 to a tiny bit faster.

As it stands now the HD 7750 is a direct replacement for the 6770, but the 7770 will only be a direct replacement for the HD 6850 for most people one-two months from now.

We'll have to wait and see what NVIDIA will bring to the market.

Hmm, I guess things have changed very recently then. I remember looking at this recently and looking at how abysmal AMD's GPUs did. My GPU is able to get 12K PPD while a 6990 was only able to muster under 9K.

I guess the next step (and the best step) to bring GPUs to parity that Stanford could make is to eliminate the old ATI WUs altogether, OR leave them for older/slower cards and depending on which graphics card series you have determine whether to give you ATI or OpenCL WUs. The fact that they use GCN should help them in this compute-heavy application, too.

In PPW (points/watt), these could become champions, but only if they use OpenCL WUs in F@h.

EDIT: looked at the link for folding with Tahiti. Now it left me with a big "meh". Stanford needs to optimize, because we're back to square zero since this is the same situation as two-three years ago.

 

[blckgrffn]

Yeah, the current OpenCL WU's are considered beta and are only available via the v7 client. So they could be "re-scored" as well, which we know could either really help or really hurt folding on AMD.

to be honest i don't know what F@H folks do but they seem lazy to patch their AMD client i mean they even still only used 320sp. its crazy, but oh well at least amd card is significantly better at making money (bitcoin).
