Owh yes it will. You dont even know what the impact is of those robs. You dont know what the load is on the 5770 that also has 16 rob's. And offcource AMD whants you to buy the 5850 or 5870 rather then the 5830.Quote:

lower pixel fillrate but 31% higher compute power, 40% more stream processors, 31% higher texture fillrate and 66% higher memory bandwidthQuote:

Somebody care to post the official specs??
I can see this pic, though.... Are those the official specs for the 5830?
Thanks in advance :p:

With Transistor count staying the same as with the 5850, so its cut down and no new chip.
Memory: 5830 = 5850
In return for the cut down you get 75mhz higher gpu clock.

Next Mem Bandwith. HD5850 has 20% less compared to the 5870. With the 5830 its the same as the 5850. So no loss there.
As for the shaders and texture units its the same drop as from 5870 to 5850.
Then the "Major" issue the ROB's they went from 32 to 16. Well i dont think that will give a big performance hit. AMD doubled them with the RV870 because the rest also doubled.
And i dont know the design but i think they grouped the ROPs somehow so they can only disable 16 at a time. But i can be wrong.
But still i think the 16 rops are fast enough to power those 320 extra shaders. You might see a small hit in 8x AA performance but i doubt it will be mind blowing.
Overall the 5830 will be closer to the 5850 in terms of performance compared to the 5770. So you guy's worry to much.
TDP is a absolute maxium. I think it will use less or the same amount of power that the 5850 uses.

Some interesting info:
- Some AIBs will be using HD 5870 PCBs but with revised (budgetary) power distribution sections. This also makes them slightly longer than a HD 5850.
- Cards sent directly from AMD to reviewers use a carbon copy of the HD 5870 PCB + PCB components + heatsink which is likely why the card can clock so high. It may also contribute to the higher power consumption listed in AMD's documents.
- Other board partners are using HD 5770 PCBs
- Every card I have seen has a different cooler
- Price isn't listed as $200. Rather, AMD only lists a price of UNDER $250. That can mean $249 and below which I am guesisng will be dictated by the board partner's component choices.
:down: to all of them...Quote:

Fermi will determine prices this summer.
Thanks Lokinhow, naokaji and Frank M for the answers.
5830 sounds like fail lol whatever seems ati got lazy and greedy again :down:Quote:

the difference here between 5770 and 5830 is 256 bit vs 128 bit. fill rate seems slightly lower then 5770, but textures are higher, 50mhz lower core speed too. Also thought this card was going to have 1280 shaders :/

That's what all of you guys that already have the 5830 in your hands are hinting and that's what I expect from reading the specs.Quote:

Depending how it goes, this can be the perfect card for replacing my "old" 4890. I don't game a lot anymore and for the games I play (Silent Hunter 4 and race sims) the 4890 is hardly breaking a sweat @ 1920x1080 except with 8xAA
5830 seems fail, although I'd like to see what ASUS, Powercolor and XFX have up their sleeves when it comes to it before buying the 5850.
1GHz a la carte and it might be worth looking forward too.
I wouldnt bother with judging or comparing clock speeds on the 5000 series cards. They are all 40nm and most can reach up to 1 Ghz on stock cooling using MSI Afterburner.
I dont think using a 5870 PCB is good, they should at least be shorter than a 5850 since they are lower specified.
My only concern is voltage control. Most of the non-reference designs use a cheap voltage controller without software control, that will make 1Ghz core clock almost impossible.
I love ATi reference designs, including the cooler, I'll chose a HD5830 with any ATi PBC over any non-reference, in most cases cheap, Sapphire or PowerColor design.
The thing is at least in paper its not between 5770 and 5850, but 1/4 up from 5770, and between in price?Quote:

I think it's quite possible AMD might not want this card to become too popular as they might be forced to laser cut large numbers of working chips to fulfill demand. In any case let's see where this card lands before we start dissing it.
The things we know about this card thus far at least make me not regret buying a 5850.
