Possible AMD Radeon HD 7700 Series Specs Revealed

[Guest]

[citation][nom]festa_freak[/nom]I'm waiting to upgrade my 4870 (which coincidentally is being shipped to visiontek for warranty repair). I want to upgrade to a 7870. It's the perfect performance/price ratio for me. My 4870 was STILL performing very well.[/citation]

Seriously. My 4870x2 still performs at 5870 levels, albeit with no DX11 (probably why, ha) and sticking with my native res of 1680x1050 without AA, the performance is great, even in BF3. I'm waiting until Max Payne 3 is released in March to perhaps get a 7970 or better. Who knows...if your 4870 can't be repaired, they might send you a newer generation card. Here's hoping that's the case, and that Rockstar optimizes their RAGE engine a little better for PC's this time.

Ok. I'll be waiting until May actually, ha.

[citation][nom]memadmax[/nom]WTF AMD????"with performance falling between the HD 6850 and HD 6790"The way I see it, you slowest next gen video card should perform faster than last gen's fastest..... otherwise you make urself look like an ass............[/citation]Troll here often?
[citation][nom]Teholtheflamed[/nom]I didn't troll or make any otherwise anti-AMD comments, and yet I got a bunch of thumbs-down, as if I flamed. Good job, fanbois. My point, was that a 6850 can be purchased from Newegg for less than $150. If the 7770 has a suggested retail price of $150, it seems a little odd, no? That's all.I bought my HD 4850 in July of '09 for $100, 512MB version. I'm just looking for better prices so I can upgrade in my price segment and have it be worth it three years later . . .what is so wrong about that?[/citation]Previous gen hardware is typically cheaper than equal-performing new releases, especially if they include new architecture and are more power/heat efficient. This is quite common, at least until vendors sell down the older stuff. So buy the older stuff and get a better deal now, suck it up and buy the newer gear, or just continue to wait. Either way it doesn't make a lot of sense to whinge about it.

You're not really making a whole lot of sense out of this situation. Typically, performance of newer tech matches the price (or close to it) of what is being replaced regardless of model number. A 7770 will not cost the same as a 6770 when it is released because it will be a more powerful/newer card. The price is about the same as the 6850 because the performance of each card will be about the same. Add in some new features, cost of designing a newer card and/or architecture, some tweaks here and there, then there is the justified marginal price increase. The MSRP of the 7770 is assumed to be around $150, but that is just speculation. We obviously don't know the actual price yet, but MSRP is generally a little higher than actual anyway (especially when rebates kick in).

.......and now we know what the final Wii U GPU will be: the HD 7750

GFlOPS pretty much match what the early overheating dev kits had in them (which was a rumored HD 4850). This card runs a lot cooler with similar performance, less watts and a low price. The new Wii U dev kits could very well be based on something very similar albeit being a custom GPU of course. Nice!

I think AMD needs to try consolidating its lineup to make it far less confusing here. Each new generation now sees a 900, 800, 700, 600, and 500 GPU available retail, with the exact spacing between them rather variable; the only certainty is that there's a solid progression. I think AMD should re-think and work on focusing making each section target a specific audience; 900s for the extreme crowd, 800 for the "bang-for-the-buck" performance crowd, 700/600 for more mainstream/midrange, and 500s for cheap, cool-running cards; perhaps targeting the HTPC crowd. (And of course, 400/300s can remain garbage OEM toss-ins)

The problem I see here is that Tahiti has 32 cores, (2048 SPs) and Pitcairn 24, (1536) yet we suddenly drop down to 10 (640) for Cape Verde. While so-far, cut-down versions of Pitcairn can have as few as 1280 SPs (20 cores) that still leaves us a huge gap: enough that even one or two more cards (a Radeon 7830?) really isn't going to fill it.

That, and I still remain a bit dubious about this information. After all, I still can't help but note that the Cape Verde Islands are very much NORTHERN Atlantic Islands, not SOUTHERN. So what's to say they're guaranteed to be using GCN instead of VLIW4?

If the Wii U is coming out this year, it won't be a 7000-series card. Given the much-lengthier development cycles for complete consoles (since there's multiple components, PLUS the integration of them all) by necessity they have to use more dated components. Otherwise you'd wind up with a sort of "Duke Nukem Forever" issue. A classical example is the PS3 using a G71 when G80-based GeForce 8800s were out and about.

Pretty good stats if that's accurate. They cut 30 watts off the 6670 and added ~20-30% or more performance. Not bad for a 128bit card.

I'm waiting for the 7850 but that's rumored for March.

 

[tomfreak]

is this going to be worth the upgrade for reasonable gain performance while cutting the power consumption over 9800GT?

My old thing 9800GT is still hasnt break yet, it seems still able to run most of the games before 2011 @ decent quality @ 1680x1050 @ 30-40fps.

 

[madjimms]

So it has LESS stream processors than my 5770? my 5770 has 800 shader units (stream processors) & the 7770 only has 640? WTF? it also has less memory bandwidth.....

 

[Kamen_BG]

How can that GPU be made of 1.5 billion transistors if its weaker than the 5770?

 

[alidan]

got to love how me mentioning i want 1.5 or 2gb of ram on the 5770 and not wanting to spend the 3-400$ for a gpu with much gets down voted to nothing... i want to use larger textures in games without causing stability problems.

 

[Pherule]

If the 7750 and 7770 are going to be 128-bit then they will be worthless to me as an upgrade. I expected the 7750 to have 192-bit and hoped the 7770 would have 256-bit.

Guess we'll be waiting for the 7800 series and the GTX600 series to force the 7800 prices down.

 

[mikeangs2004]

Does the 7770 have an external power connector? I would like to see a more powerful card that does not need a power connector.

 

[ismaeljrp]

The 7700 series a a huge letdown if this is true. SMH, they should have done the 7770=6870, 7750=6850... They really need to stop recycling the 4870's performance into hd x7xx series or higher cards. FFS how the hell do you go up 3 generations and still keep that type of performance over ~$125?

 

[ismaeljrp]

I guess I'll just have to wait about a year before I can get 560ti/6950 class performance for ~180.

 

[belardo]

AMD seems to have trouble creating the excitement of the 5000 series...

Understandable... with 95% of the gaming market now on CONSOLES... how many people really need a good gaming card? Spending $500~1000 for graphics cards seems foolish without the titles.

If the HD7750 will offer HD6770 performance but need less than HD6670 power, then I see that in another "how low can you go" rig, probably with an i3-2100T. It won't max new games, but should play them all on "High" very nicely.

 

[kjack]

Are we sure these aren't then specs of the 7670 and 7650? I thought 7770 and 7750 were already semi-confirmed as having 892 and 832 shaders, respectively.

 

[TeraMedia]

Anyone here know if PCIe 2.1 or 3.0 has a slot power rating high enough for the 7770? I know that the rating was suppsoed to have increased at one point, but I don't remember when or how much. Is it still 75W (in which case the described 7750 doesn't need a connector. WOOT!), or is it now 150W (in which case the 7770 doesn't need to use one on new MBs either. WOOOOT!)?

I need something low-power to replace an ailing HD 2600 XT (yeah, it's that old) on an HTPC that supports casual gaming. The shortest 5770 with full slot exhaust just doesn't quite fit. Maybe one of these new models with a redesigned cooler will do the trick.

Would be interesting to know how's 7770 crossfire will scale.

With so low power usage and if they would scale very well then I think this would be perfect card for crossfire.

The architecture is same as with 7970 and 7950, so the scaling should be guite near the same as with those GPUs. For those test where crossfire works, it is guite good, but this is so new that there are many games where scaling is not working at all. It will take time for drivers to mature. It is even more important in sli and crosfire than in single gpu situation.

7670 and 7650 are rebranded old chips. Only 77xx and higher are using the new architechture.

Oh hey, I somehow missed that the 7600 were silently released as OEM rebrands.

It just seems weird that there's going to be a huge gulf between the 7800 and 7700 chips.

Going from 128bit(77xx) to 256bit(78xx) memory interface will do that.

I can't wait until these parts come out, the 6K series they are replacing price's will drop like a rock!
