email to a friendReady for a spell of Monday-morning speculation? Good, 'cause our sources tell us that AMD has a Radeon HD 5890 in the works.
We're told the card will be a single-GPU solution, and judging by the nomenclature, it should become AMD's quickest.
Later this week, the Sunnyvale, California-based semiconductor manufacturer will launch its first next-generation DirectX 11 graphics cards, the ATI Radeon HD 5850 and ATI Radeon HD 5870 - with the latter said to be priced at €319.99.
Speculation suggests that AMD will unleash a dual-GPU variant - the Radeon HD 5870 X2 - shortly after the launch of its 5000-series products, but a time frame for the Radeon HD 5890 remains unknown. Conjecturing somewhat, the card is likely to feature a faster-clocked RV800 GPU and we presume it'll slot in between the Radeon HD 5870 and Radeon HD 5870 X2.
The news should come as no surprise considering that AMD previously usurped its Radeon HD 4870 with the faster-clocked 4890. Nonetheless, a potential Radeon HD 5890 is something to bear in mind for those planning on getting their hands on AMD's soon-to-be-fastest single-GPU solution, the Radeon HD 5870.

They'll probably hold onto the 5890 until they see what the fastest single GPU NVIDIA can produce.
That would be the smart option, no point introducing it now only to be beaten by nvidia two months later.Quote
As with the 4890, power consumption is a big issue, especially when using three of four cards. Word is the 5870 is 170W, so the 90 variant will hopefully be 190W or less.
TDP of 5870 is 188W. 5850 is 170W. Considering 5850 has 10% of it's SIMD and TMUs disabled, and has a 10% less TDP, which may or may not actually be accurate in real power consumption, I'm just assuming something to do with 40nm leakage is requiring voltage to be similar. Not unlike 4770 which was capable of high clocks, but had a very high initial TDP for what it was.
Supporting this, it's been reported 1ghz on the stock cooler is very possible...like 4890...so it would seem 1ghz can be done at less than 225W. I'm assuming of course a 5890 would be clocked so it achieve over 3TF (938mhz), at least the percentage higher 4890 was (13.3%...964mhz), and 1ghz just looks pretty on the box.
That being said, consider these things:
1. The PCB power connectors on 5870 have the solder points and room for an 8-pin connector in place of one 6-pin. The 4890 has this as well, and was used in OC models that were clocked up to 1ghz.
2. 5870 uses 4-phase power (5850 3-phase) with room for one more. 4870 used 3, 4890 used 5.
Does indeed look like history will repeat, in a newly tiered fashion. If I had to guess, it will launch at 5870's price when 5870/5850 settle (~$200/300). There's also the possibility it will launch at a better price to beat it's closest GTX300 rival in price/performance upon their launch. That would be something to see...ATi spoiling an nvidia launch! :embarrassed:
Whatever be the case, I expect whatever the stock clock is on 5890, it will also be on the 32nm XT refresh...or darn close. Seems ATi has found themselves a tick-tock strategy of sorts!
1. Release moderately-clocked and harvested parts on initial process yield (4870/4850...5870/5850)
2. Release parts towards highest feasible clock on matured process yield (5890...or the refined 55nm rv790/4890). OC part with 8-pin connector an idea of 90 part on next-gen.
3. Start again on next process using **70/**90 clocks as baseline clocks.
Damn, guess I'll have to wait until 32nm to see if we have 800/1000/1200mhz parts and that actually happens. Bet it does. That's a pretty smart way to both get to market quickly and complete a product stack, IMHO.Quote
Attempting to extract more money by creating artificial performance boundaries? Sounds like a tech company, alright.Quote

Ohhh.. the irony :) Nicely put!
It is nice to see some kind of naming convention take shape here though.... What is this... the 3rd generation of hardware that roughly uses the same product codes in the roadmap? That must be a first!Quote
