this is the old 7990, not the new 7990 malta..i would not pay $1000 for this as it under-performs the new 7990 maltas.
No, no it doesn't. Identical cores, identical specs. This new one just has way worse cooling and is power limited to 375W. It can NOT mine scrypt.
yes identical tahiti cores, but not same specs. the new one is clocked higher than the old one by at least 25mhz each core.
what sources do you have to say the new one has worse cooling? tomshardware and a few other websites say the new one has much better cooling. it boggles my mind why a new card that came out about a year after the first 7990 would have poorer cooling. So please provide evidence.
Who cares about stock clocks when you're spending $1k :/ We all buy 800-900Mhz 7950s and slap them at 1100.
Full comparison was done here:
https://109.201.133.65/index.php?topic=187328.0Oh dogie, where do I even start? Your thread only states pre 7990 numbers and what you think theoretical new 7990 #s are? If you are gonna do a unbiased and factual review, get numbers for both sets of hardware: In this case 7990 pre malta and 7990 malta (new). You only have real #s for 7990 pre malta and the other numbers are what you theorize / speculate they will be for a new 7990 malta. This creates a huge lack of credibility in my mind.
Its common sense.... I'll state it step by step for you though...
1) The cores are IDENTICAL. Stock clocks are different, but clock for clock identical.
2) Because they are identical, power consumption is going to be VERY close. +/- 15W.
3) Hence, clock for clock these hash identically.
4) The cooling solutions are designed for their TDP. One has a TDP of 375W and one at 525W.
What more do you want? Why would I spend $2k on these shit cards just to prove you wrong?
I'm not the moron who thinks power usage and cooling is the same. 7990 malta uses 375-389watts at full load for both cores total.
The 7990 Malta runs cooler than previous 7990, so again you are wrong.
If a card runs cooler then it will clock even the same core higher simply if the design makes it run cooler. This means that hashrate will be higher. DURR?
Also the cards sell for $900-$1100, not $2000. So again you are wrong.
Finally go look at tomshardware, guru3d and anaandtech for reviews before you go spouting off that you are right.
You give bad advice and information to the community when you just start blowing numbers and misleading information out your ass.
