[zol.com.cn] HD 7870 rumors surface better than 560ti!!

[IonusX]

i got rumor based paperwork out of asia. basically the 7870 will be a supped up hd 6930 tricked out with more ram, a die shrink, among other things. all in all the changes would make it worse than the 6970 but better than a 560ti (384 core)
that leaves the 570, 560ti(448 core) and 6950 as rough performance competitors which is a pretty healthy list.

now take this news with a grain of salt, this info is from a site that oversells as much as its on the ball. thats all folks, rock on!

That's exactly where I expect it to be. Anything less would be disappointing; Anything more would be icing on the cake.

it says rumor

What ljonberg means, is that you have to include the site you have the rumors from, in the topic title. If not, IDC will be along shortly to help you out.

With that out of the way, 560ti performance is too low. I hope 7870 is 6970 speed with factory OC versions, and that it doesnt get referance model launch at all.

i sourced its right there

6970 is ~gtx570 in a lot of games used on benchmarking sites, the 560ti-384 version is close to 570, so if the 7870 is around there then it hits the mark as everyone expected, reaching 6970 speeds. The huge advantage is two-fold, GCN is very good in every game and scales great with OC, something VLIW4 isn't. Secondly, since the 7970 is only ~200W in games, and its much bigger compared to the 7870 die size, i suspect the 7870 is going to be around the ~120W mark.

Getting that much performance for so little power is awesome-sauce no matter how you put it.

 

[Borealis7]

imagine the potential O/C gains on that thing, in relation to the price...oh my!

 

[atticus14]

hopefully 78xx series has the same tessellator engine as its big brother, combined with OC'ing this should be a monster for the price. Really interested in all these cards because of OCing and GCN efficiency, wonder how far down the chart a person can go and still get a good upgrade; im still holding on to my core 216 and its finally gotten to the point where i feel a huge need to upgrade, all the 28nm rumors earlier this year made me play the waiting game.

 

[Crap Daddy]

If it's better than the 560Ti then it's also better than the 6950 leaving the 7890 to replace the 6970 and it's NV equivalent the 570 and the 7950 to battle it out with the 580. Seems plausible.

 

[MrTeal]

I would be terribly disappointed in a 6950 level of performance out of a $299 HD7870 if the leaked pricing is correct. I could just buy a HD6950 today for $210AR, or a 2GB version for $230. Even with the extra OC headroom and cooler running, if the HD7870 launches at the $300 mark and isn't around as fast as a 6970, it will be a poor value.

 

[Arkadrel]

I dont think the 7870 will be less than 6970 performance.

heres why:

7870 (rumored specs):
1408 steam processors
88 texture units
24 RoPs
176 GB/s memory bandwidth


the 7970 is a 2048 steam processor chip, however its around 50% faster than the 6970.

Then we do some educated guessing:

(1408/2048) x 150% (of 6970 performance) = 103% of a 6970.

However it doesnt end there... the 7870 cores are clocked higher than the 7970's by around 3% or so.

103% x 1.03 (3% higher clocks) = ~106% of 6970 performance.

Then add in aditional driver improvments and by the time the cards are out,
you ll probably see the 7870 beat the 6970 by around 10% or so.

First of all, what the heck is an HD6930? Secondly, the HD7870 is going to be a die shrink of HD6970 with slightly higher clock speeds, so it will be faster than a HD6970 by a small amount. If this HD6930 is not a typo and is slower than a HD6970, then you are very much mistaken.

Incorrect. HD7870 is a die shrink of HD6970. HD7850 is a die shrink of HD6950.

HD7870
1536 Stream Processors
96 Texture Units
128 Z/Stencil ROP Units
32 Color ROP Units

HD7850
1408 Stream Processors
88 Texture Units
128 Z/Stencil ROP Units
32 Color ROP Units

Both will have slightly higher clocks than HD6970 and HD6950 so they will be a tiny bit faster out of the box but with far less heat and power consumption so they will overclock a lot better.

^ I think those are the old rumored specs ... AMD would be wise not to re-badge their mainstream GPUs (their bread and butter), even if their die is shrinked

They are. The 7870 will probably end up between the 6950 and 6970.

We have not really seen any links, but we have seen 7770 ES samples being tested about, and they correspond to above hardware.
The 7770 tests right under the 6850.
All this is obviously by design.
Maximize profits.
The 7870 will bench slightly faster than the 6950.
All imho.

That's not true at all, both the 77xx and 78xx series are based on the new GCN architecture.

7870 = get all your 6xxx cards at bargain prices before they run out!

Rebadging something as a lower model number for the next gen, especially with a die shrink, is common practice and has been done for a very long time.

The only problem with rebadging is when it's the exact same card and you don't make any changes, you just increase the model number (and possibly price).

The entire GTX500 lineup is basically a rebadged GTX400 lineup, it's pretty much the same GPU, just with a few tweaks e.g. number of functional units (if that, e.g. GTX460 -> GTX560 non-Ti).
Then there's the 8800 which had a million different numbers, but most of the time they went down.

Even if it was an HD6900 which was die shrunk, calling it an HD7800 is a way of making things obvious in terms of relative performance. It will also be better than the HD6900 because of lower power consumption.

Things like HD5770 -> HD6770 are bad rebadges that don't help when both products are sold alongside each other.

 

[VulgarDisplay]

It has been confirmed for quite some time that 77xx, 78xx, and 79xx are all GCN chips and not rebadges. So expect to see some of the same overclocking potential out of these chips.

lol!

So your q8300 is a "rebadge". The entire SB line line up except the first flagship, The ph2 lineup, athlons, the 6950 is a rebadge, 5850, 6850 and below.....everything except the top skew of any product ever released. The 7950 and all other GCN will be. your logic.

Also, i know of 3 8800gts that are still used daily from the minute they were bought. Add that to the 1 a guy in this forum who still has one and wants to upgrade....thats 4 that never "went down". So there! LOL!

Most of the 8800s and variants are still functioning to this day. You would be amassed at the legs of that killer GPU. There are many ppl here at the ATF still using them.

 

[Lonyo]

My point was that "rebadge" is a meaningless term, and not a negative one, since pretty much everything can be called a rebadge in some way or another.

It's only a problem changing name only if you mislead consumers by doing so, examples being the Geforce 4 MX series and the HD6770.

a rebage is when you take a card, without any changes to it architecturely or physically (say removeing or adding, RoPs,TextureUnits, shaders ect) and name it something differnt than it first appeared as.

Only then is it a rebage.

The 77xx,78xx,79xx, are all new cards and not rebages.
Saying otherwise is incorrect, end of.

For example: Geforce 8800GT, Geforce 9800GT, Geforce 8800GTS-512, Geforce 9800GTX, Geforce 9800GTX+, Geforce GTS 250

For example: Geforce 8800GT, Geforce 9800GT, Geforce 8800GTS-512, Geforce 9800GTX, Geforce 9800GTX+, Geforce GTS 250

Great chip, it was. :thumbsup:
