[FUD] Radeon HD 7970 is around 30 percent faster - Page 5

i think i would be happy with a 10fps increase. i think i could squeeze another 10 out of a nice overclock... thats damn good imo.

I'm expecting at least 20 fps better on Crysis Warhead than HD 6970, and THEN OC it to make it 30fps better. This card, if the information is true, will not get my money; instead it probably will go to a 580.

You have about 6-8months after the AtI release.
6-8 months is nothing.

Judging from the 3D Mark scores there (only ones I could find from a quick search) the 5870 was roughly 30% faster in 3d Mark than the 4890 (which was the highest end single GPU in the ATI line at the time)...and we all know in the real world the 5870 ran circles around it

Feel free to correct me if I'm wrong though

Very useful post.

Compared to Intel's maybe 10% performance gain going from 32nm to 22nm.. 30% looks like a ton. Also, 7970 has 30% gain on SPs (which scale dang good), ~10% clock increase, 384-bit bus vs. 256-bit, almost certainly more ROPs, oh and a new architecture (6000 series added probably less than half of the SI architecture changes).. it'll be over 30% gain. Even the source article says gaming performance is a decent amount more than 30% gain over 6970.

looking at specs alone the 7970 has 33-50% more hardware, and that's without considering any architectural improvements* or clock-rate advantages. (* always possible changes in architecture are for the worse, but that doesn't seem likely) so for news of only 30% faster its a huge disappointment, but at the level of which it becomes very hard to believe. 40% would be believable yet disappointing because that's at the lower end of what we're all hoping for based on hardware specs, I know most of us are hoping for 50+%.

heck, other variables might be resolution and/or CPU bottlenecks

except you can't compare CPUs to GPUs, GPUs are highly parallel so they can benefit far more easily from adding "more cores". This would be more akin to a new intel CPU only being 30% faster in the most heavily threaded apps even though it has 33% more cores, higher IPC, higher clockrate, and 33-50% more cache. It just doesn't add up.

Adding more cores is right up AMD's alley

Nvidia adds more cores too. The thing is, more graphics cores really help gaming performance.

If that's true, then I'm waiting for nVidia.

And when nVidia releases their first round of 28nm high performance you'll only have a few months for AMD 8000 series on a fully matured and likely more optimized 28nm process...

You can always wait for the other guys to release something better, but then your always waiting, and we're all playing...

I kind of like the fact that AMD and nvidia are on a sort of opposite release schedule now... gives us something new more often heh... I just want 6900 series prices to take a drop...

I won't wait much longer once I have used my 6870 for at least a year, if not half a year. I would crossfire it, but I've heard problems about microstuttering so I'm patiently waiting for a single-GPU card that would equal at least crossfire 6870 (6990 preferred).

lawl, just enough time for a new lineup to show up from AMD. I would suggest that, given the wild speculation on the 79xx cards this month, I would take those Keple benches we saw as complete FUD to pull the sparkle out from under AMD.

Everyone is also forgetting the other KEY component to the equation.

If AMD releases a card with sub-30% improvement in performance, but can offer it at a really competitive price against NVidia's hotter, expensive chips, they could make a killing (despite the 'lackluster' improvement over last year's cards). That's where AMD could really shine.

But if these cards offer only modest changes, except with a $550 pricetag, forget it. People will see through that in two seconds.

HD 8000 anyone?

thats how i feel.

Just getting my 6000 card and then 7000 series comes to punch me in t he face smile.gif

Im not sure if those benches are correct, i seen a bench where HD 5000's -> 6000's . . . .
Maybe i should try Nvidia next. . .
