AMD Radeon HD 7700 Specifications
  1 / 3    
In the coming week, AMD will release its Radeon HD 7700 series, which aims to increase its competitiveness in the sub-$200 market. The latest specifications exposé reveals AMD's new design strategy: Instead of increasing components such as stream processors and ROPs, which would increase transistor counts, and unnecessarily increase power draw, AMD is counting on a lesser number of better-configured Graphics CoreNext stream processors. While the previous-generation HD 5770/6770 "Juniper" GPU featured VLIW5 stream processors, the new "Cape Verde" GPU, which will go into making up Radeon HD 7770 and 7750, will feature GCN stream processors. Apart from architectural performance improvements, AMD is counting on increased clock speeds to do the trick. The specifications are listed below.

I didn't know they created a website for this /blink.gif' class='bbc_emoticon' alt=':blink:' />
Anyway, I think it's rude of AMD to attack nVidia like that. From what I've read across the Internet, Verdetrol=nVidia ( http://www.legitreviews.com/news/12443/ ). No one plays 3DMark, and the 1 GHz GPU >>> cheapest way to boost performance. Basically, a HD 7770 is an overclocked HD 5770. The funny part is the theoretical single-precision floating point performance: 1280 GFLOPS for HD 7770 versus 1360 GFLOPS for HD 5770. I hope this will be able to stand against some lower end Kepler GPUs. (GTX 640 and GTX 650). I don't think the majority are interested if their graphics card draws 80 W or 110 W, not even for HTPCs. It's not like the HD 7770 is a 7" long card, right? What's truly important, in my opinion, is the performance per watt, and I'm not talking about compute performance. I'm talking about gaming perfomance/watt. I can watch 1080p movies just fine on a HD Graphics 2000, with a TDP around 30 W.

Verdetrol=Nvidia?? how?

I know nvidia has Verde drivers. Perhaps in relation to that?

Core i7 960 @4.14Ghz 180x23 1.3v Liquid cooled

Gigabyte G1. Assassin

EVGA GTX 560 Ti "Maximum Graphics Crysis 2"

Cooler Master HAF-X

Corsair Dominator GT CMT12GX3M3A2000C9 RAM

RMA broke my 580 SLI. Now I have a 7970 and a GTX 580 gathering dust, looking for a buyer.

Indeed, nVidia has Verde drivers. In some languages, Verde means green. And nVidia's logo is green.

AMD's 7770 is a new chip from the ground up. It was designed from the get go to consume very little power while maintaining performance of the previous DX 11 x770 series. If you look at the overall goal of Southern Islands that's obviously the entire point of the lineup. Absolute computational performance crowns aren't all that important anymore; the number bulk purchasers care most about is performance/watt.

You get the same level of performance, but at a lower TDP. That's a start. But I believe most people aren't really concered about TDP, as they are about performance. At least, for the moment it's the only option. If you want fluid 1600p gaming or multi-monitor setup, you need a 150+ W TDP card.
About the whole Imbecilin idea, I seriosly doubt that's something out of nVidia. At least, there's no record of a website created for that and it's a CGI. It wasn's a physical item, anyway.
I have a saying, if you will: nVidia is building GPUs, like AMD does CPUs, and ATi (AMD) builds GPUs, like Intel does CPUs.
nVidia prefers more cores, while AMD prefers more per-core efficiency (VLIW). Yes, I believe nVidia really needs to consider something like that. That explains the lower TDP for AMD cards. If it's not there (physically), it doesn't consume energy.
You know what they say: Real men use real cores! /rolleyes.gif' class='bbc_emoticon' alt=':rolleyes:' /> http://www.techpowerup.com/92485/-Real-Men-Use-Real-Cores-AMD.html
D1llw33d, my friend, don't take this as fanboy-ism towards nVidia, from my side. I just don't like people/companies that like to keep themselves proud.

You have to remember that these are just rumoured specs, it might not be true. I'm also disappointed with the 640 stream processors, the HD5770/6770 had 800 stream processors. Fair enough it does use GCN rather than VLIW5, so it should still be slightly faster. Just last month, this was leaked showing the HD7000 specs. This could be wrong aswell, but at least the HD7770 has more stream processors than the HD5770/6770.

How many GPUs do you buy?

No gamer will buy more than 3-4 mid range GPUs tops whereas the people who buy for OEMs, and IT departments care about power draw, thermal envelopes and performance per watt more than any absolute performance numbers.

From 640 stream processors to 1280 stream processors? Just shows how you shouldn't listen to these rumours and just wait. Although I am liking the HD7750 using less than 75w and therefore not requiring a 6-pin power cable.

Within two months of launch OEMs like powercolor will underclock and/or passively cool a 7770 to get that down to 75w or less as well.
