AMD "Oland" Radeon HD 8800 Series SKUs Unveiled

[seronx]

The head scratcher was the comparison between the 7870 and the 8870.

HD 7870 = 1280 * 2 * 1 GHz = 2560 GFlops/2.56 TFlops (as per my original post)- correct?
Yet the graph states 2.25 TFlops

So I was wondering if the 2.25TF calc for the HD 7870 was also a factor in the 3.94 TF for the new card (i.e. 12% lower than theoretical). If the Oland is a 1792 shader part, then whomever put the graph together has trouble multiplying three numbers together it would seem...since 3.94TF is a theoretical number, and therefore the theoretical number for the 7870 is 2.56TF - not 2.25

Probably a typo.
The DP number is correct.

7870 -> 160 FMA GFlops
8870 -> (1792 / 16) * 2 * 1.1 = 246.4 FMA GFlops

good news, but from otherside - is there anything new in gaming world that require/will require something more than one good old hd 5870 to run on ultra @1080? while there will be "newest" consoles with GPUs of XT1800 level... well you get my "optimistic" point of view

Wii U => ~5670
PS4 & XB3 => ~7870/670

 

[dj-electric]

xbox720 is rumored to have the GPU equivalent of the HD6670
PS4 about the same, also AMD based, maybe Fusion/
Both far from HD7870's level anyway.

There is a chance that both M$ and Sony updated the spec when the 28nm GPUs came out.

Playstation 4 has 1120 GCN ALUs
Wii U has 400-480 ALUs

5670 -> 400 ALUs @ .775 MHz @ 40-nm
6670 -> 480 ALUs @ .8 MHz @ 40-nm
Wii U -> 400-480 @ 1.0+ GHz @ 32-nm <-- H2 2012
XBX/PS4 -> 1120-1344 GCN/Kepler @ 1.0+ GHz @ 28-nm <-- H2 2013 - H1 2014

Playstation 4 -> APU monolithic silicon (AMD²)
Xbox 3 -> APU interposer (AMD + Nvidia)

nice nice. good to see new gfx cards coming out soon

It kinda feels like they are competing with NV on how fast they can bring out a new series of cards.
I dont care how often they produce a new set of cards, I just want the new series to be more relevant, not just marketing.
A great example is the 5xxx to 6xxx series, where improvements were only efficiency.

 

[Frick]

Correct, but i was talking about the new games, HD58** series has enough to play atleast 1 more year's future games (Exceptional are there but still)

I still don't get you. You mean it wouldn't work with new games if it's not "supported"? It will work perfectly.

Anyway, does this mean there will be no 76xx cards?

 

[sic_doni]

the new graphic card will be cheaper...faster...and more power efficient

 

[Completely Bonkers]

Just... as... I... was... about... to... put... money... down... for... 660Ti

but this is a Q1.13 launch ... so up to 6 month wait.

 

[hardcore_gamer]

We don't know yet. There is also a possibility for a holiday season launch.

It would be pointless now, they couldn't get them out in enough time before the marketing department said its time for a new series.

There are OEM 7570 and 7670 cards but those are 6570 and 6670 rebags.

 

[nt300]

I am still waiting for the 7990

Jokes aside, I was pretty set on a couple 7970s toxic but if specs are already coming out I guess I'll wait

Looking like the HD 8870 will be faster and cheaper than HD 7970. I wold wait if I were you.

 

[renz496]

^still we don't have any idea when this card will comes out. if you keep playing waiting game you'll never buy anything in the end lol. IMO the best way to get a card is to see the one that will fit your need the most not based on which is the latest one

btw if AMD really did comes out with 8800 series before 8900 series it could mean they get very nice competition from nvidia

 

[Nordic]

I wonder if the 8800 series will have 3gb vram

 

[renz496]

I wonder if the 8800 series will have 3gb vram

most likely the card will come with 2 GB as standard.

 

[Delta6326]

I hope they don't drop the balls (Support) on their HD 5*** series, My HD 5850 is still fast enough and serving in my secondary system.

Don't worry sense they dropped support for the 4*** series I get way better frames for new games.

 

[Casecutter]

It kinda feels like they are competing with NV on how fast they can bring out a new series of cards.

It kind'a appears AMD could care less about Nvidia being so tardy with their mainstream response, and are just sticking to their product development as normal. Though it does seem AMD intends to strike at the Nvidia's soft spot 660/660Ti first and grab the lions share.

I'd love to see it come before Christmas buying season and I believe they could... that would put Nvidia in the corner wearing the pointy hat!

8850 may have:
1536 Cores (@ 2prim per clock) x 975MHz = 2.995200 TFLOPS
-------------------------------x 925MHz = 2.841600 TFLOPS
96 TMU x 975 MHz = 93.6 GT/s
---------x 925MHz = 88.8 GT/s
32 ROP x 975 MHz = 31.2 GP/s
--------x 925 MHz = 21.3 GP/s

8870 may have:
1790-1792~Cores x 1050MHz = 3.759 - 3.763 TFLOPS old 7950@800MHz is at 2.867
112 TMU = 117,6 GT/s
32 ROP = 33,6 GP/s

Wii U => ~5670
PS4 & XB3 => ~7870/670

I'm pretty sure that the Wii U is running a 5770 , I may be wrong though. But that is a big step for Consoles, because XBOX was running the ATI XT series

 

[alwayssts]

I'd just like to point out (not to gloat, but to be rumor-weary) I've been saying these EXACT part would occur (right down to the freaking clock speeds) for like...six months.

It may be true, and obviously I expect it more-or-less to will be, but yeah.

Things to consider:

*Should perform like 7950 and 7970 ghz ed at stock (if not memory constrained), 8850 10% better than 7870 overall.
*Makes a lot more sense priced at 259-269/359-369 (660ti/670), because amd has been shown to really like those approx. prices at launch.
*1792sp would be bandwidth constrained with 6gbps/256-bit at around 900mhz (obviously one can overclock and the gtx600 series shows how far 6ghz ram can go)
*8850 should have one power connector and in theory could hit similar clocks to stock 8870 within 150w, perform similar to 660ti.
*die size sounds exactly what I figured it would be, as does TDP.

The two things that don't compute are the ram/shader setup and the price. Either AMD expects people to understand they will need to overclock the ram, the specs are wrong, or amd is short-sighting themselves (which benefits us).

 

[Hilux SSRG]

I know the pricing [and performance numbers] is not set in stone yet but the 8870 is still priced too high. Don't know what the performance will be like but I wouldn't shell out more than $225-250 for those 8870 levels of performance.

Nice! Hope to see soon in Kaveri APU too...?
