The HD7790 "Bonaire" New GPU from AMD [Edit: NOW WITH 100% MORE REVIEWS!]

[Arkadrel]

Power efficiency went up alot with the 7790:

http://www.techpowerup.com/reviews/Sapphire/HD_7790_Dual-X/24.html


Its about 17% slower than a 7870 in cysis 2 (1680x1050).
Its above the 6950 and sidelines to the 560ti in this benchmark.

Meanwhile the 7870 uses like 50% more power than the 7790.

Avg power use (cysis 2 bench):
650ti = 66 watts (about 11% slower than 7790, in this bench)
7790 = 69 watts
7870 = 103 watts (about 17% faster in this bench)
6870 = 119 watts (slower than the 7790 in this bench)
6950 = 121 watts (same performance as 7790 in this bench)
560ti = 148 watts (same performance as 7790 in this bench) (more than TWICE the power use)

Its on top of the list of highest Performance-per-watt cards on Techpowerup.

I can't wait to see the 256-bit version of this architecture. The huge memory speeds and good power draw these are getting should mean a card that competes near the HD 7950.

I wonder if AMD is making this and calling this 7000 series to phase out the die harvested parts. This could replace the HD 7850 1 GB which is rumored to be phased out, and eventually they can replace the 7950 with the larger version of this.

I cant wait to see a highend version with these tweaks (384bit bus). 7790 is exactly 1/3 of rumoured 8970 non-oem GPU:

             7790      8970 (3x7790)
shaders:    896          2688
bus w. :   128bits     384bits
rops:        16             48
tmus:       56             168

3x 7790 speed = titan performance

At the prices this card is going for it's a complete rip-off here in the UK. Paying the same money for less performance over a HD 7850 1GB.

Way to go AMD. :thumbsdown:

At least in the USA it is $30-$40 cheaper and falls in line with price/perf.

 

[Olikan]

bonaire have increased the perf/watt so well, that i think that this old table might be possible...

The 7790 load power consumption is very good but the HD 7850 doesn't exactly suck the juice considering it is around 20% faster.

yeah...TDP should go a bit higher, not decrease...:hmm:

but still possible :whiste:

 

[hansmoleman8]

Annnd Bonaire is now irrelevant.

$149 GTX 650 Ti Boost is to Bonaire what GTX 670 was to Tahiti. NVidia totally embarrassed AMD.

The 650 Ti Boost has more raw performance capability than the 12 month old, stable, Pitcairn (7850). It doesn't even make sense on paper. 192 bit memory bus, fewer shaders, fewer ROPs

 

[blastingcap]

7850 is faster on average than gtx 650 Ti Boost, sorry to burst your bubble. 7850 remains a good card and overclock vs overclock the gtx 650 Ti Boost is even less likely to keep up. gtx 650 Ti Boost should still outperform the new 7790 though, stock vs stock or oc vs oc.

It's interesting to see these two positions flip flop .

Tahiti: better performance+lower price
GK104: Uses less power.

650ti Boost: Better performance+same price
Bonaire: Uses less power.

I can't believe people have these superficial discussions. Doesn't anyone care what it's really about?

AMD releases a card to fill the performance gap between 7770 and 7850. nVidia, and everyone else, knew the performance target of bonaire and releases a card that's virtually the same performance as the 7850, knowing it will outperform the 7790. nVidia waited until Bonaire was released to be certain they had their targets correct. If Bonaire was faster or cheaper than they thought it was going to be, they could have reloaded. It wasn't necessary though because AMD was completely transparent on Bonaire before release.

I care because I stupidly bought a 450W Corsair PSU and dont want to have to upgrade my PSU just for a graphics card.

Where have you seen it as the same as 7850??

On ave I've seen it for 120-125; some going into 130ish range; that's on ebuyer - no where have I seen it as the same price as 1gig 7850....

1 gig 7850 cheapest I've seen is 149.99

Close in price yes on some of the OC models; but not the same

My post was made before the GTX650Ti boost was revealed. Now 7790s are being sold for ~£20 less than they were a few days ago.

A few days ago in the UK the 7790 was overpriced and at similar prices to a 1GB 7850 which was a scam. It is now at a much more realistic price point thanks to the 650Ti.

Cost to manufacture. Taking into account the narrower bus and the smaller die, expect that Bonaire can be sold for quite a bit less than 650 Ti Boost can while still making a profit. The launch price of Bonaire is frankly just a bit high. However, looking at the specs, mainly the 160mm² die and the 128-bit bus, the card should cost about the same to make as 5770 did, and that sold for around $100 for most of it's life.

I expect the pricing on Bonaire to fall to a level where 650Ti can't reach it, and then sell a lot.

 

[tincart]

I ended up picking up a 7790 since I was going to get Bioshock Infinite. The $150 price tag for the OC edition was a bit high, but it gets me the $60 game I was going to get anyway, and the 7790 will be a decent upgrade over the 4770 currently sitting in my second system. I do love me some bundle deals.

Bonaire is still not a 75 W card. It needs 6pin PCIE power. Unless they start selling it for $129, there is no reason to not get a $149 1GB 650 Ti Boost. Unless you want Bioshock Infinite of course.

And Bonaire is new custom silicon, not a binned part.

You dont get it.. but performance wise, 650TI goes vs 7790, and 650TI boost vs 7850. Boths vs cards that are on smaller dies, OCs better, and are more efficient. All AMD has to do is to lower their prices and bye bye Nvidia.

price of a hd7790 is 0 usd via bitcoin. just use a calculator to see what I mean.

https://bitclockers.com/calc

so using prices as part your argument is foolish. now if you want to say the nvidia 650 ti boost plays games better that is okay.

it 10 days you would earn 13 bucks.

that is using 250 hash rate

16 cents for a k-watt of power

86 usd for a bitcoin.

I started with 7 mill difficulty and a 20% increase rate


in 30 days you would earn 39 dollars brings price to 110 down from 150. plus you get a game with it.

in 60 days you get back 70 dollars brings price to 80 down from 150.

in 90 days you get back 94 dollars brings price to 56 down from 150.

 

[blastingcap]

Calculators that assume constant difficulty? Lol, difficulty is skyrocketing and there is no guarantee prices will follow suit, in fact, the bubble may burst.

And that is what we are waiting for. But so far we see no action from AMD.

 

[Rvenger]

7790 needs to be at $120 and push the 7750 down to $60 and the 7770 to $80-90.

MY CALC link Has 20% a month built in to it. you can pick more if you want.
so 7,000,000 first 0 to 30 days
8,400,000 30 to 60 days
10,080,000 60 to 90 days.

the card will cost less then 60 bucks after 90 days. so using price against a close nvidia card will make a nvidia lose. Some time soon maybe july or august this will not be true. and then you can use price against amd cards.
