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

[Erenhardt]

All in all I'd say prices represent performance quite well, except GTX650Ti has to go down a bit.

And that is disappointing. I thought 7790 will put some pressure on existing cards bringing their prices down a little bit.
Imagine if we have this situation for 5 years. If every card released from now on will be priced accordingly to their performance, taking fixed performance/$ ratio, we will end up with GPU prices of $5000 for a card.
That is why I think that new GPUs need to have better performance/$ than existing ones.

It doesn't put direct pressure.
But if enough people stop buying the cheaper cards or the more expensive cards to go with the 7790, soon those cards will stop moving units and have growing stocks.

Then you can be certain there will be price pressure.

Get a 660 Ti and call it a day my friend. gl

 

[Midwayman]

Just to get it out of the way: Ha ha ha yes they actually named it Bonaire. Yes that sounds like boner with a french twist. This card is going to give everyone in the ~$150 market a Bonaire etc etc etc you're very funny and original.

Weird thing is that its a caribbean island. I thought the naming scheme was all south pacific. Bonaire has great shore diving and a not a whole lot else. Part of the ABC islands- Aruba, Bonaire, and Curacao.

pretty decent upgrade option for HD4800/5700/6700 (and GTS250, 450, GTX 260...) owners I think.

I agree. If you have a 5770 / 550Ti or lower tier card, this isn't a bad option. Of course spending $30 more (not including rebates) for a 7850 makes far more sense. But if you value a quiet card with very low power usage and are willing to dial down a setting, then the 7790 wouldn't be the worst purchase. Techpowerup is stating that it's offers the best power consumption-to-performance ration of any modern card. Some people value efficiency.

No AA so you remove most of the memory constraint. I don't really consider 29 AvFPS in BF3 playable though.

 

[Arkadrel]

sometimes it does really good:

Like here:
the 560 has a minimum fps of 17.
the 650 has a minimum fps of 11.

So for a game like Crysis 3, the 7790 crushes the 650 and 560.

Same with F1 2012:

Probably a full product stack refresh outside of Titan, while AMD is stable through 2013 and adds two new 7 series cards to fill in gaps.

I still think the next upcoming GK110 geforce SKU will be the 700 series flagship card. 320-bit memory, 13 SMX's, DP performance cut down, probably the same or very similar clocks as Titan. $649 GTX780 5gb vram, $599 GTX780 2.5gb vram. GK114/204 (whatever GK104 refreshed is called) gets a 5-7% performance bump at the same or slightly lower TDP that it's at now and will start out at $449. That's my guess!

Anyways back on topic, 7790 is a good performer.

 

[Mopetar]

Not a bad card and fills a good niche. Depending on the game, this card has some value. I'm also curious about how well it can overclock, as the Sapphire card can apparently keep it plenty cool, even with the moderate factory overclock.

The core overclocks fine but the limited memory bandwidth keeps the gains down. So far it appears the memory clock is locked.

It is not...

7.0GHz+

 

[Arkadrel]

1765mhz... thats.... 7060mhz on the ram.

Lmao at 113 GB/s memory bandwidth on a 128bit bus.

Thats nothing short of Impressive!
AMD must have put some serious work into the memory bus with this chip.

A 7850 (stock) has 153 GB/s with a 256bit bus.
113 GB/s is ~74% of that, while useing a bus width half of the 7850's.


* found the review, its from:
http://www.techpowerup.com/reviews/Sapphire/HD_7790_Dual-X/29.html

Those are some decent gains.
Its beating the 6970 pretty solidly (card with 176 GB/s memory bandwidth)

17% GPU overclock & 10% memory overclock = 15%+ performance increase.

That seems like a decent enough overclock, for a card that already has so high memory speeds.

**looked at afew other Techpowerup reviews of the 7790,
they all have memory over 1750+ in the overclock part of the reviews.
So it doesnt seem like its just a lucky card type of thing.

Whatever AMD did on the bus side for the new architecture its impressive.

 

[SithSolo1]

It is not...

7.0GHz+

Glad to be proven wrong though I swear I saw a review or two say they couldn't get the memory to budge.


Any thoughs as to whether a PICO PSU would be enough for an Ivy i5(stock or under-volted), mini-itx mobo, 1 ssd, and this 7790? Finding a case to fit it might be an issue but you could make one potent little portable rig if it would run.

PicoPSU-160-XT.

160watts to work with.... dont think it would be safe to run a Ivy i5 + 7790 on that.
If you "underclock" the 7790, and use like a i3-3220 or something, it could probably work.

But why not just get a slightly bigger Case, and a "real sized" PSU?
It would still be portable, and then you could still have a i5 Ivy + overclock ect.

HD8000 middle-end card (HD8850) with 256bit bus will have nice memory bandwidth if they can pull those kind of freqs.
It may be a reason why there is only 128bit bus. They were able to get 2x 64bit controllers to work with 7GHz freq. Having wider 256bit bus means 4 controllers. It was easier to make 2 good quality ones than 4 average?

 

[Arkadrel]

@Erenhardt

I doubt it. I think its a matter of :

increased ram speed = Xa more power use.
increased bus width + slower speed ram = Xb more power use.

compaireing those, and looking at die size differnces ect.
Cost of fast ram + small bus width vs slower cheaper ram + wider bus.

AND....

most importantly, I think its a matter of.... can it be done?

Can it be done? looks like it.

I think its just showing whats possible with GCN 1.1, as people are calling it. It might even have been a test, to see if they could get bus's running at those speeds (for future use). Where the 7790 was a test to see how it would turn out.


A 256bit bus, that has GDDR5 running at 7.0ghz+ would mean you had:
256x1.765 / 8 x 4 = ~225 GB/s memory bandwidth.

A 7970 has about 264 GB/s Memory bandwidth.

Thank you for the suggestion but the Prodigy is one of the largest mini-ITX cases on the market and an order of magnitude larger than what I'm interested in. I was looking at something more along the lines of this: http://www.xtremesystems.org/forums...-in-America)&p=5177118&viewfull=1#post5177118

TPD of an i5 is 77w or less and its 85w for the 7790. Thats 162w. Add another 10w for the mobo, cpu fan, and SSD. Yeah its pushing it but it might be possible as you won't be maxing the CPU and GPU at the same time unless benchmarking. Only thing to really worry about is the power spike on boot up.

Even an undervolted and underclocked i5 will beat an i3 in most programs/games.

Now all I need is the cash to test it.

Edit:
Another option would be this case: http://hardforum.com/showthread.php?t=1750863
Its larger but I could use a full SFX PSU. Then again with a full SFX PSU I could run an i7 with Titan if I had the money.

Sith you are mad and I like it

and jesus this card is mad......hell tempted to pick one of these bad boys to play with on spare system for the kid.....so I can have mine back when he comes over

 

[BeauCharles]

Good card, but I just don't buy 1GB anymore.

 

[Red Hawk]

I bet there will be custom designs with 2 GB, at a bit of a price premium.

 

[VulgarDisplay]

AMD slid their Bonaire into the price gap nicely.

 

[psolord]

That's quite probable, but there are 7850s with 2GB below 200 already and we all know what the 7850s can do. I don't see the point.

 

[GodisanAtheist]

The fact that it took 95 freaking posts for one of these brings a tear to my eye. YOU DUN GROWD UP VC&G. YOU A MAN NOW.

 

[BallaTheFeared]

Probably slot between the 1GB 7850 and 2GB 7850 and totally not be worth it.

Also lol @ the hardware haven review, $400 worth of $130 1080p screens with a $100 grapics card - makes perfect sense me to.
