Topic: 7990 revealed..... (Read 6664 times)

The 7990 could very well be a better mining card than the 7970s due to the lower power consumption of the dies. AMD's been harvesting dies for a year now, the power draw of a 7990 is quite a bit lower than two 7970s or a Devil13.

Yep, but in gaming performance is similar to 2x7950 despite having almost the same specs as a 7970 on paper (same shader count, just 50 MHz reduction in core clock). If that translates to mining as well then the lower power consumption isn't much of a gain.

You keep quoting this as if its a fact, yet you've produced no evidence. I have two computers sitting next to me, one with 2x7970, and one with 2x7990. My eyes confirm something which your made up facts do not.

You don't have the Malta 7990s.

Check any review and you'll see it is 15-20% slower than actual 7970 CF, as far as gaming is concerned. A 50 MHz drop in core clock alone wouldn't do that.

HardOCP specifically tried increasing PowerTune to 20% which is the max and that didn't help things either (though this did work on the previously released custom 7990s)

No I don't have Malta 7990s, but clock for clock they are IDENTICAL to the current PC cards, of which I have 2. I can SEE ON MY SCREEN, 7950s v 7990 cores.

Its like me quoting a review taken out of context to try and convince you that you're not really 5'9", you're 5'6".

Mining is considerably less power intensive than gaming (or Furmark), so I would guess power throttling won't be nearly as big an issue. Litecoin mining might be a different case though. Open case thermal throttling shouldn't be that bad either, since that huge open cooler would love to be in free air.

It shouldn't even be a contest at this point, but for some stupid reason 7970s are getting more expensive lately. It's tough to find even vanilla ones in qty for much under $400.

Is the only benefit of a 7990 space/slots? Because 7970s are $400. Am I missing something?

Also, why the hell are 5970s so expensive?

Right. The 7990 is hard to justify at $1k even when you factor in the slot savings. From all reviews I've read it also seems to perform similarly to 2x7950 as well.

If each 7990 is $400, this is $1000 and includes $300 of games, is twice as dense and will hold price better then.....

You won't get $300 for the included games, most of them are old and only worth $5-10. $100 best case.

Seeing as it performs similar to 2x7950 in gaming which only cost around $280-300 each I don't think it will hold its price well. Initially it will just because AMD said stock will be limited.

Crysis 3, Bioshock Infinite, Farcry 3, all old games ofc...

I have both 2x7950 and 2x7990s. They perform like mid range 7970s in terms of overclocking rage [still im UNDERVOLTING]. It helps to actually have some evidence for what you are saying, helps prevent being wrong.

I'm well aware of what I'm saying.

Let me break it down for you.

Crysis = $25
Bioshock = $25
Far Cry 3 = $20
Far Cry 3: Blood Dragon = $10
Hitman: Absolution = $10
Sleeping Dogs = $10
Deus Ex: Human Revolution = $10

Hitman, Sleeping Dogs, Deus Ex are all old and have poor resale value as a result. That's nowhere near the $300 you quoted. You can buy 3x 7950s for the price and get 3 copies of Crysis and BioShock, which will net more return than the other games included with the 7990.

As I said the GAMING performance of the 7990 is similar to 2x-7950 going by the recent round of benchmarks. I do not know if this will be the case for mining -- haven't seen anyone bench the Malta cards under mining conditions. Still, as resale value of a card largely hinges on what gamers will pay for it later on, that's something to consider.

Could get 2-3 7970 for that price?

Imagine the heat coming from case with dual 7990. Shocked
