AMD "Tahiti LE" Brand Named Radeon HD 7890

A little earlier this week, it was reported that AMD is working on a new Radeon HD 7800 series graphics card based on the company's 28 nm "Tahiti" silicon. According to a new report, the so-called "Tahiti LE" SKU has been brand named Radeon HD 7890. Although clock speeds, core and memory configurations are still under the wraps, the new SKU, according to the report, is being designed to be 15% faster than GeForce GTX 660 on average, while being similarly priced. AMD is gunning for the crucial X'mas shopping season, when apparently, a few cool people gift high-performance graphics cards.

15% faster then the GTX 660? but the 7870 is on par now (12.11 drivers) with the GTX 660 Ti so how much faster is this 7890 over the GTX 660 Ti is the real question?

Also price, i can now pick up a 7870 for as low as $220 so this should be what? $250? AUS $$$

and there it is. We all knew it would be a 7890. I personally think it should be a 7930 because it is tahiti

A weird release as the 7870 and 7950 are close enough as it is

maybe they figured that 7890 sounds better/stronger than 7930, I think so at least

Errrm.. not "on par" according to W1zzard review : http://www.techpowerup.com/reviews/AMD/Catalyst_12.11_Performance/23.html

Trailing 8% @ 1200p, 5% @ 1600p, and 8% @ relative performance.

... so this will have old 7950 performance then?

i think they are aiming at people who gift gifts to themselves :laugh:

Who cares about over all % if its over 10% then ill listen, if its under its just not worth the extra $100 for that few %.

If you look at each gaming benchmark to see the difference in FPS its like 3-5 frames at most, that's nothing, in my eyes thats on par and for $100 less its WAY better then a GTX 660 Ti (and I was considering a 660 Ti as my next upgrade) ;)

The defferance between HD7870 and HD7950 is so small in performance and price, that if HD7890 well be released, it's either HD7870 or HD7950 that gonna simply die and won't sell as much

Here's a guess:
It's named HD 7890 in order to avoid bundling it with all the games that come with the HD 7900 series.

The larger bundle would probably be the only factor making the HD 7950 more appealing.

just to meet market positions, NV does the same so I dont see why everyone is bitching about it.

Radeon fans seems to care when their cards can beat NVIDIA cards with similar amount/close percentage (i.e. 7970 Ghz vs GTX 680, 7950 vs GTX 670 with this 12.11 drivers) :laugh:

Well, I guess double standard FTW!!!

well youre the same way so whats the problem?

Just remember the same company who makes the Radeon Video Cards makes your CPU.

As a matter of fact, I don't care :roll:

Owning CPU or GPU made by X company does not mean I can't say "not so good" things about them :roll:

Just to be fair let me say a bad things about NVIDIA : their new driver (310.33 BETA) suuuuucks for me, crashing on NFSMW and Borderlands 2 (again).

Not me, it all comes down to Price/performance, and i own more Nvidia based computers then i do AMD so im no fan of either company.

When the GTX 660 Ti came out i was going to get two, i had my heart on that from the day i saw the benchmarks, yes the cost at the time was a little more then the 7870 but the price/performance was good enough for me to get the GTX 660 Ti. BUT then AMD dropped the prices on all the HD 7*** series and put out those new drivers I completely changed my mind as the 7870 was the better choice. Glad I waited to be honest.

Thats just how it happened :ohwell:

You can say it that way :laugh: Although the fact that my last 2 Radeon cards (5770 and 5850) burnt and dead made me a bit traumatic LOL.

But hey, brand A, brand B, what's the big deal? As long as it works and keep making money (I work with my PC, FYI).

Did you buy them online or from a retailer because Living where you are im sure quality parts are hard to get.

Ive had owned an Asus mobo in past and worked/replaced several for new customers in the past, I dont blame the chip maker but the board maker itself.

There is a user here who owns a 590 and one of the GPUs burned up, he was trying to figure out how to disable SLI on it but there is no way to do so, when a single GPU burns up on a board like that, expect the working unit to die along with the rest of the PCB

I bought it from a retailer.

Hey, don't be mean LOL.
It's EASY to get a quality parts here. Seriously, you can order GTX 690 or 7970 in the morning and paid it in the afternoon.
Here's one example retailer in my country GPU inventory : http://www.enterkomputer.com/vga.php, or this PSU inventory : http://www.enterkomputer.com/psu.php.
Not so bad, huh? LOL :D

The main problem, though, is always the price. All of you in US, EU, or Australia always talks about rebate and price cuts. Well, in my country you have to wait for a long time before the price cuts applies.

We got Super Flower here :D Not so bad, huh? LOL.

Im not being mean im being honest, I was in Korea and funny enough couldnt get any quality pc parts. When a New product releases its always high on the price- i just know certain countries have tariffs on import parts etc. I heard AUS is pretty slow to get parts in too for retailers. Also it would appear that the retailers dont do price cuts even though the chip makers give an order to slash the prices.

... so this will have old 7950 performance then?

http://img.techpowerup.org/121108/Capture1024.jpg
I think the purpose is clearly to have a product that performs as well or slightly better stock/overclocked at 1080p than 660ti in the 660 price bracket. I also think (as I've said before) this is the place 8850 will sit. The dead obvious spec they need to hit for efficiency/price is 1536sp, 925/5000 and 256-bit, but I believe 660ti was given >150w because they knew amd was going to beat them (with 7870 over 150w and slightly less efficient...8850 under it and more efficient) hence 660ti was carved out to slightly exceed that performance level. A make-shift 7870, if you will, based on a more efficient spec because of the greater resources of gk104, perhaps also influenced by hiking the tdp allowances and placement of 670/680 early on. Point is, this will probably be some take on that carved out of Tahiti and ~185w (just like 660ti)...and we really don't need it. Tahiti was not built for where 1536sp fits. If it's a high-speed product, it needs 6gbps and 256-bit. If it is a power-efficient product, it needs 5gbps/256-bit.

Consider the bw matching/separation game more closely. 7870 needs 4500mhz on a 256-bit bus (hence why you see a lot of 1200/5400 overclocks, given the max 170w tdp one would imagine it was engineered with that realistic overclock in mind). Original 7950 needs 5040mhz on a 256-bit bus at stock...a bad overlap...but the boost version that replaced it (stock 'up to 925mhz boost'...which essentially equates to a 7870 at 1295mhz) would need over 5800mhz at 256-bit. Note the hard locks at 5800mhz for the 7800 series and how 1295mhz/5800 is not exactly common for the process or 5gbps-rated ram, so 7950 boost actually does what the original does not...create market separation within their own stack. This is how products are made these days...A convoluted mathematical nightmare...but even slight mismatching of resources within a price bracket is the difference between an appealing and unappealing all-around product.

I can't help but wonder if this will exist in-part so amd can stop cutting the 7950 price. Since 660ti core efficiency and tdp sits directly between 7870 and 7950, up until now the larger and stronger 7950 has been going almost buck-for-buck with 660ti. Considering gk104 is smaller/less expensive to produce, and both 7870/7950 are probably dangerously close currently to the price they want to launch 8800 series...it would make sense to try to force something into that spot so the next series has at least a little shine on it.

Best amd could do, imho, is give it 384-bit/5gbps and 1.5gb. That should temper the tdp allocation for the ram some-what, and the core could clock to use some of that bw if allowed to scale. In theory, they could stock clock it up to ~1025mhz stock, which would for all intents and purposes be similar-to-faster than 660ti, and would react similar to 2GB buffer without being memory/bw bound.

Hey.. I'm just kidding :p

That's exactly what happened in my country. New stuff is coming early (you can even pre-order) but always high on the price and you must wait for a long time for a price cuts.

Hopefully the price cuts will come here ASAP, it will be good if it happens before Mayan's doomsday. LOL.
